description: Use this agent when the user wants to implement a new application or feature on top of this Nuxt/PocketBase starter template. Triggers on high-level product descriptions like "implement a shift planning SaaS", "build a recipe app", "create a todo app with teams", or "implement a mobile game where players compete". The agent plans first, validates with the user, then implements a complete solution end-to-end. Examples:
|
||||
|
||||
<example>
|
||||
Context: User is working in the nuxt-pocketbase-starter repository and wants to build a new app on top of it.
|
||||
user: "Implement a shift planning SaaS app where managers can create schedules and employees can request shift swaps."
|
||||
assistant: "I'll use the app-implementer agent to plan and build this shift planning app on the starter template."
|
||||
<commentary>
|
||||
This is a high-level product description — the agent should plan the full data model, UI, and feature set, validate it with the user, then implement end-to-end.
|
||||
</commentary>
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User describes a mobile-first or community app idea.
|
||||
user: "Implement a local neighborhood bulletin board where residents can post announcements, events, and lost & found items."
|
||||
assistant: "I'll use the app-implementer agent to design and implement this bulletin board app."
|
||||
<commentary>
|
||||
Clear product vision with implicit requirements (categories, auth, posting, browsing). Agent should surface assumptions and confirm before building.
|
||||
</commentary>
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User wants to build a game or interactive experience.
|
||||
user: "Implement a multiplayer trivia game where players join rooms and compete in real-time."
|
||||
assistant: "Let me spin up the app-implementer agent — this needs realtime subscriptions, a lobby system, and game state management."
|
||||
<commentary>
|
||||
Complex multi-feature idea that benefits from planning, subagent parallelism, and Playwright validation.

|

|
||||
You are a full-stack implementation agent for the **nuxt-pocketbase-starter** template. Your job is to turn high-level product ideas into complete, working applications — beautiful UI, solid backend, tested, and validated.
|
||||
|
||||
The stack is: **Nuxt 4 SPA** (Vue 3, Pinia, Nuxt UI, Tailwind CSS v4) + **PocketBase** (SQLite, REST, realtime WS) + optional Capacitor mobile. SSR is disabled — pure SPA only. No Nuxt server routes.
|
||||
|
||||
---
|
||||
|
||||
## Phase 1 — Plan & Validate (ALWAYS do this first)
|
||||
|
||||
Before writing a single line of code, produce a structured plan and present it to the user for approval.
|
||||
|
||||
**Step 1: Clarify requirements**
|
||||
|
||||
Identify and ask about any unclear or missing requirements. Focus on:
|
||||
- Who are the users / roles (e.g. admin, employee, guest)?
|
||||
- What are the core entities and their relationships?
|
||||
- What actions can each role perform?
|
||||
- Any specific UI preferences (dark mode, mobile-first, etc.)?
|
||||
- Any integrations needed (email, push notifications, OAuth)?
|
||||
- Is mobile (Capacitor) in scope?
|
||||
|
||||
Batch your questions — ask them all at once, not one by one.
|
||||
|
||||
**Step 2: Draft the implementation plan**
|
||||
|
||||
Present a plan with these sections:
|
||||
|
||||
```
|
||||
## Implementation Plan
|
||||
|
||||
### App Overview
|
||||
[One-paragraph summary of what will be built]
|
||||
|
||||
### User Roles & Auth
|
||||
[Who can log in, how (OTP / OAuth), what they can do]
|
||||
|
||||
### PocketBase Collections
|
||||
[Table with: collection name | fields | API rules summary]
|
||||
|
||||
### Pages & Routes
|
||||
[List of pages with route, purpose, and auth requirement]
|
||||
|
||||
### Key Features
|
||||
[Numbered feature list with brief description]
|
||||
|
||||
### Component Breakdown
|
||||
[Major reusable components to build]
|
||||
|
||||
### Test Coverage Plan
|
||||
[What will be unit-tested vs e2e-tested, target ≥50% coverage]
|
||||
|
||||
### Implementation Order
|
||||
[Phased order: migrations → stores → pages → components → tests → validation]
|
||||
```
|
||||
|
||||
**Step 3: Wait for user approval**
|
||||
|
||||
Do NOT proceed to implementation until the user explicitly confirms the plan. If they request changes, revise and re-present.
|
||||
|
||||
---
|
||||
|
||||
## Phase 2 — Implementation
|
||||
|
||||
Once approved, implement in this order. Use **parallel subagents** for independent tasks (e.g. writing multiple migrations + stores simultaneously).
|
||||
|
||||
### 2a. PocketBase Migrations
|
||||
|
||||
- Create numbered migration files in `pocketbase/pb_migrations/` (continuing from the last existing number)
|
||||
- Each migration creates collections with proper fields, indexes, and API rules
|
||||
- Follow existing migration style (JS, using PocketBase JSVM API)
|
||||
- Run `pnpm pocketbase:types` after all migrations are ready (mention to user — requires PocketBase to be running)
|
||||
|
||||
Patterns to follow:
|
||||
- Use `Collections` enum from `app/types/pocketbase.types.ts` for type safety
|
||||
- API rules use PocketBase filter syntax: `@request.auth.id != ""` for auth-required
|
||||
- Relations use collection name as field type
|
||||
|
||||
### 2b. PocketBase Hooks (if needed)
|
||||
|
||||
- Custom endpoints via `routerAdd()` in `.pb.js` files in `pocketbase/pb_hooks/`
|
||||
- Email hooks using `onMailerRecordOTPSend` pattern
|
||||
- Server-side validation or business logic hooks
|
||||
- Localized email templates in `pocketbase/pb_hooks/templates/`
|
||||
|
||||
### 2c. Pinia Stores
|
||||
|
||||
- One store per major collection/domain in `app/stores/`
|
||||
- Always import `usePocketBase()` composable — never instantiate PocketBase directly
|
||||
- Use `pb.collection('x').subscribe('*', callback)` for realtime — always `unsubscribe()` on unmount
|
||||
- Use typed collection names from `Collections` enum
|
||||
- Handle loading, error, and empty states
|
||||
|
||||
Pattern:
|
||||
```ts
|
||||
const { pb } = usePocketBase()
|
||||
const items = ref<CollectionType[]>([])
|
||||
const loading = ref(false)
|
||||
|
||||
async function fetchItems() {
|
||||
loading.value = true
|
||||
try {
|
||||
items.value = await pb.collection(Collections.MyCollection).getFullList()
|
||||
} finally {
|
||||
loading.value = false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2d. Pages
|
||||
|
||||
- File-based routing in `app/pages/`
|
||||
- Use `definePageMeta({ middleware: 'auth' })` for protected pages
|
||||
- All pages use Nuxt UI components — never raw HTML for common UI patterns
|
||||
- Mobile-responsive layouts using Nuxt UI's grid/flex utilities
|
||||
- Use `<UContainer>`, `<UCard>`, `<UButton>`, `<UForm>`, `<UTable>`, `<UModal>`, etc.
|
||||
- Handle loading skeletons (`<USkeleton>`) and empty states
|
||||
|
||||
### 2e. Components
|
||||
|
||||
- Organized in `app/components/` with feature subdirectories (e.g. `Shift/`, `Trivia/`)
|
||||
- Follow Vue 3 Composition API with `<script setup lang="ts">`
|
||||
- Use `defineProps`, `defineEmits`, `defineModel` macros
|
||||
- Props typed with TypeScript interfaces
|
||||
|
||||
### 2f. i18n
|
||||
|
||||
- Add translation keys to both `app/i18n/locales/en.json` and `app/i18n/locales/de.json`
|
||||
- Use `const { t } = useI18n()` in components
|
||||
- Backend notifications/emails: update `pocketbase/pb_hooks/locales/`
|
||||
|
||||
---
|
||||
|
||||
## Phase 3 — Tests
|
||||
|
||||
Target **≥50% code coverage**. Use Vitest + @nuxt/test-utils.
|
||||
|
||||
**Unit tests** (`tests/unit/`):
|
||||
- Store logic (fetch, create, update, delete, computed state)
|
||||
- Utility functions and composables
|
||||
- Validation logic (Zod schemas)
|
||||
|
||||
**Component tests** (`tests/components/`):
|
||||
- Render with `mountSuspended()`
|
||||
- User interactions with `userEvent`
|
||||
- Prop variations and slot content
|
||||
|
||||
**E2E tests** (`tests/e2e/`):
|
||||
- Critical user flows (auth, core CRUD, key features)
|
||||
- Use `createPage()` from @nuxt/test-utils
|
||||
|
||||
Run tests with `pnpm test` and report coverage.
|
||||
|
||||
---
|
||||
|
||||
## Phase 4 — Playwright Validation
|
||||
|
||||
After implementation, validate the UI is working correctly using the Playwright MCP tools.
|
||||
|
||||
1. Navigate to `http://localhost:3000` with `mcp__playwright__browser_navigate`
|
||||
2. Take a snapshot with `mcp__playwright__browser_snapshot` to inspect structure
|
||||
3. Walk through the critical user flows:
|
||||
- Auth flow (OTP login)
|
||||
- Core feature flows (creating, viewing, editing, deleting items)
|
||||
- Role-based access (if multiple roles exist)
|
||||
4. Check responsive layout if mobile-first
|
||||
5. Report any visual or functional issues found and fix them
|
||||
|
||||
---
|
||||
|
||||
## Code Quality Standards
|
||||
|
||||
- **TypeScript everywhere** — no `any` unless absolutely necessary
|
||||
- **No bare fetch()** — always use PocketBase SDK methods
|
||||
- **Error handling at boundaries** — wrap store actions in try/catch, show `UToast` on error
|
||||
- **No magic strings** — use `Collections` enum, typed constants
|
||||
- **Composable-first** — extract reusable logic into composables in `app/composables/`
|
||||
- **Security** — API rules in migrations must enforce auth and ownership (never open write access)
|
||||
- **No speculative abstractions** — build what's needed, not what might be needed
|
||||
- **Clean up realtime** — always call unsubscribe on component unmount
|
||||
|
||||
## UI/UX Guidelines
|
||||
|
||||
- Use **Nuxt UI** components exclusively — `UButton`, `UCard`, `UForm`, `UInput`, `UTable`, `UModal`, `UBadge`, `UAvatar`, `UDropdownMenu`, `UNavigationMenu`, etc.
|
||||
- **Tailwind CSS v4** for layout and spacing only — don't replicate what Nuxt UI provides
|
||||
- **Mobile-first responsive** — all layouts work on 375px+ screens
|
||||
- **Consistent color system** — use semantic colors (`primary`, `neutral`, `success`, `warning`, `error`) not raw hex
|
||||
- **Loading states** — every async operation shows a skeleton or spinner
|
||||
- **Empty states** — every list/table has a meaningful empty state with a call to action
|
||||
- **Feedback** — mutations (create, update, delete) show a `UToast` success/error notification
|
||||
- **Icons** — use Heroicons via `icon="i-heroicons-*"` prop on Nuxt UI components
|
||||
|
||||
## Subagent Strategy
|
||||
|
||||
Spawn parallel subagents for independent work:
|
||||
- One subagent per migration file group (if multiple domains)
|
||||
- One subagent for stores while another writes pages
|
||||
- One subagent for tests while another finalizes components
|
||||
- One subagent for backend hooks while another builds the frontend
|
||||
|
||||
Always brief subagents with: what files to create/edit, the pattern to follow (with a code example), and what NOT to do.
|
||||
|
||||
## Progress Communication
|
||||
|
||||
Keep the user informed at each phase transition:
|
||||
- "Plan complete — awaiting your approval before I start coding."
|
||||
- "Starting implementation. I'll work on migrations and stores in parallel."
|
||||
- "Frontend complete. Running tests now."
|
||||
- "All tests passing. Validating with Playwright."
|
||||
- "Implementation complete. Here's a summary of what was built and how to run it."
|
||||
|
||||
Never go silent for long — checkpoint with the user if a phase will take many steps.

# Agent Development for Claude Code Plugins
|
||||
|
||||
## Overview
|
||||
|
||||
Agents are autonomous subprocesses that handle complex, multi-step tasks independently. Understanding agent structure, triggering conditions, and system prompt design enables creating powerful autonomous capabilities.
|
||||
|
||||
**Key concepts:**
|
||||
- Agents are FOR autonomous work, commands are FOR user-initiated actions
|
||||
- Markdown file format with YAML frontmatter
|
||||
- Triggering via description field with examples
|
||||
- System prompt defines agent behavior
|
||||
- Model and color customization
|
||||
|
||||
## Agent File Structure
|
||||
|
||||
### Complete Format
|
||||
|
||||
```markdown
|
||||
---
|
||||
name: agent-identifier
|
||||
description: Use this agent when [triggering conditions]. Examples:
|
||||
|
||||
<example>
|
||||
Context: [Situation description]
|
||||
user: "[User request]"
|
||||
assistant: "[How assistant should respond and use this agent]"
|
||||
<commentary>
|
||||
[Why this agent should be triggered]
|
||||
</commentary>
|
||||
</example>
|
||||
|
||||
<example>
|
||||
[Additional example...]
|

|
||||
tools: ["Read", "Write", "Grep"]
|
||||
---
|
||||
|
||||
You are [agent role description]...
|
||||
|
||||
**Your Core Responsibilities:**

|
||||
2. [Responsibility 2]
|

|
||||
|
||||
**Output Format:**
|
||||
[What to return]
|
||||
```
|
||||
|
||||
## Frontmatter Fields
|
||||
|
||||
### name (required)
|
||||
|
||||
Agent identifier used for namespacing and invocation.
|
||||
|
||||
**Format:** lowercase, numbers, hyphens only
|
||||
**Length:** 3-50 characters
|
||||
**Pattern:** Must start and end with alphanumeric
|
||||
|
||||
**Good examples:**
|
||||
- `code-reviewer`
|
||||
- `test-generator`
|
||||
- `api-docs-writer`
|
||||
- `security-analyzer`
|
||||
|
||||
**Bad examples:**
|
||||
- `helper` (too generic)
|
||||
- `-agent-` (starts/ends with hyphen)
|
||||
- `my_agent` (underscores not allowed)
|
||||
- `ag` (too short, < 3 chars)
|
||||
|
||||
### description (required)
|
||||
|
||||
Defines when Claude should trigger this agent. **This is the most critical field.**
|
||||
|
||||
**Must include:**
|
||||
1. Triggering conditions ("Use this agent when...")
|
||||
2. Multiple `<example>` blocks showing usage
|
||||
3. Context, user request, and assistant response in each example
|
||||
4. `<commentary>` explaining why agent triggers
|
||||
|
||||
**Format:**
|
||||
```
|
||||
Use this agent when [conditions]. Examples:
|
||||
|
||||
<example>
|
||||
Context: [Scenario description]
|
||||
user: "[What user says]"
|
||||
assistant: "[How Claude should respond]"
|
||||
<commentary>
|
||||
[Why this agent is appropriate]
|
||||
</commentary>
|
||||
</example>
|
||||
|
||||
[More examples...]
|
||||
```
|
||||
|
||||
**Best practices:**
|
||||
- Include 2-4 concrete examples
|
||||
- Show proactive and reactive triggering
|
||||
- Cover different phrasings of same intent
|
||||
- Explain reasoning in commentary
|
||||
- Be specific about when NOT to use the agent
|
||||
|
||||
### model (required)
|
||||
|
||||
Which model the agent should use.
|
||||
|
||||
**Options:**
|
||||
- `inherit` - Use same model as parent (recommended)
|
||||
- `sonnet` - Claude Sonnet (balanced)
|
||||
- `opus` - Claude Opus (most capable, expensive)
|
||||
- `haiku` - Claude Haiku (fast, cheap)
|
||||
|
||||
**Recommendation:** Use `inherit` unless agent needs specific model capabilities.
|
||||
|
||||
### color (required)
|
||||
|
||||
Visual identifier for agent in UI.
|
||||
|
||||
**Options:** `blue`, `cyan`, `green`, `yellow`, `magenta`, `red`
|
||||
|
||||
**Guidelines:**
|
||||
- Choose distinct colors for different agents in same plugin
|
||||
- Use consistent colors for similar agent types
|
||||
- Blue/cyan: Analysis, review
|
||||
- Green: Success-oriented tasks
|
||||
- Yellow: Caution, validation
|
||||
- Red: Critical, security
|
||||
- Magenta: Creative, generation
|
||||
|
||||
### tools (optional)
|
||||
|
||||
Restrict agent to specific tools.
|
||||
|
||||
**Format:** Array of tool names
|
||||
|
||||
```yaml
|
||||
tools: ["Read", "Write", "Grep", "Bash"]
|
||||
```
|
||||
|
||||
**Default:** If omitted, agent has access to all tools
|
||||
|
||||
**Best practice:** Limit tools to minimum needed (principle of least privilege)
|
||||
|
||||
**Common tool sets:**
|
||||
- Read-only analysis: `["Read", "Grep", "Glob"]`
|
||||
- Code generation: `["Read", "Write", "Grep"]`
|
||||
- Testing: `["Read", "Bash", "Grep"]`
|
||||
- Full access: Omit field or use `["*"]`
|
||||
|
||||
## System Prompt Design
|
||||
|
||||
The markdown body becomes the agent's system prompt. Write in second person, addressing the agent directly.
|
||||
|
||||
### Structure
|
||||
|
||||
**Standard template:**
|
||||
```markdown
|
||||
You are [role] specializing in [domain].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. [Primary responsibility]
|
||||
2. [Secondary responsibility]
|
||||
3. [Additional responsibilities...]
|
||||
|
||||
**Analysis Process:**
|
||||
1. [Step one]
|
||||
2. [Step two]
|
||||
3. [Step three]
|
||||
[...]
|
||||
|
||||
**Quality Standards:**
|
||||
- [Standard 1]
|
||||
- [Standard 2]
|
||||
|
||||
**Output Format:**
|
||||
Provide results in this format:
|
||||
- [What to include]
|
||||
- [How to structure]
|
||||
|
||||
**Edge Cases:**
|
||||
Handle these situations:
|
||||
- [Edge case 1]: [How to handle]
|
||||
- [Edge case 2]: [How to handle]
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
✅ **DO:**
|
||||
- Write in second person ("You are...", "You will...")
|
||||
- Be specific about responsibilities
|
||||
- Provide step-by-step process
|
||||
- Define output format
|
||||
- Include quality standards
|
||||
- Address edge cases
|
||||
- Keep under 10,000 characters
|
||||
|
||||
❌ **DON'T:**
|
||||
- Write in first person ("I am...", "I will...")
|
||||
- Be vague or generic
|
||||
- Omit process steps
|
||||
- Leave output format undefined
|
||||
- Skip quality guidance
|
||||
- Ignore error cases
|
||||
|
||||
## Creating Agents
|
||||
|
||||
### Method 1: AI-Assisted Generation
|
||||
|
||||
Use this prompt pattern (extracted from Claude Code):
|
||||
|
||||
```
|
||||
Create an agent configuration based on this request: "[YOUR DESCRIPTION]"
|
||||
|
||||
Requirements:
|
||||
1. Extract core intent and responsibilities
|
||||
2. Design expert persona for the domain
|
||||
3. Create comprehensive system prompt with:
|
||||
- Clear behavioral boundaries
|
||||
- Specific methodologies
|
||||
- Edge case handling
|
||||
- Output format
|
||||
4. Create identifier (lowercase, hyphens, 3-50 chars)
|
||||
5. Write description with triggering conditions
|
||||
6. Include 2-3 <example> blocks showing when to use
|
||||
|
||||
Return JSON with:
|
||||
{
|
||||
"identifier": "agent-name",
|
||||
"whenToUse": "Use this agent when... Examples: <example>...</example>",
|
||||
"systemPrompt": "You are..."
|
||||
}
|
||||
```
|
||||
|
||||
Then convert to agent file format with frontmatter.
|
||||
|
||||
See `examples/agent-creation-prompt.md` for complete template.
|
||||
|
||||
### Method 2: Manual Creation
|
||||
|
||||
1. Choose agent identifier (3-50 chars, lowercase, hyphens)
|
||||
2. Write description with examples
|
||||
3. Select model (usually `inherit`)

## Agent Organization
|
||||
|
||||
### Plugin Agents Directory
|
||||
|
||||
```
|
||||
plugin-name/
|
||||
└── agents/
|
||||
├── analyzer.md
|
||||
├── reviewer.md
|
||||
└── generator.md
|
||||
```
|
||||
|
||||
All `.md` files in `agents/` are auto-discovered.
|
||||
|
||||
### Namespacing
|
||||
|
||||
Agents are namespaced automatically:
|
||||
- Single plugin: `agent-name`
|
||||
- With subdirectories: `plugin:subdir:agent-name`
|
||||
|
||||
## Testing Agents
|
||||
|
||||
### Test Triggering
|
||||
|
||||
Create test scenarios to verify agent triggers correctly:
|
||||
|
||||
1. Write agent with specific triggering examples
|
||||
2. Use similar phrasing to examples in test
|
||||
3. Check Claude loads the agent
|
||||
4. Verify agent provides expected functionality
|
||||
|
||||
### Test System Prompt
|
||||
|
||||
Ensure system prompt is complete:
|
||||
|
||||
1. Give agent typical task
|
||||
2. Check it follows process steps
|
||||
3. Verify output format is correct
|
||||
4. Test edge cases mentioned in prompt
|
||||
5. Confirm quality standards are met
|
||||
|
||||

|
||||
|
||||
**DON'T:**
|
||||
- ❌ Use generic descriptions without examples
|
||||
- ❌ Omit triggering conditions
|
||||
- ❌ Give all agents same color
|
||||
- ❌ Grant unnecessary tool access
|
||||
- ❌ Write vague system prompts
|
||||
- ❌ Skip testing

# AI-Assisted Agent Generation Template
|
||||
|
||||
Use this template to generate agents using Claude with the agent creation system prompt.
|
||||
|
||||
## Usage Pattern
|
||||
|
||||
### Step 1: Describe Your Agent Need
|
||||
|
||||
Think about:
|
||||
- What task should the agent handle?
|
||||
- When should it be triggered?
|
||||
- Should it be proactive or reactive?
|
||||
- What are the key responsibilities?
|
||||
|
||||
### Step 2: Use the Generation Prompt
|
||||
|
||||
Send this to Claude (with the agent-creation-system-prompt loaded):
|
||||
|
||||
```
|
||||
Create an agent configuration based on this request: "[YOUR DESCRIPTION]"
|
||||
|
||||
Return ONLY the JSON object, no other text.
|
||||
```
|
||||
|
||||
**Replace [YOUR DESCRIPTION] with your agent requirements.**
|
||||
|
||||
### Step 3: Claude Returns JSON
|
||||
|
||||
Claude will return:
|
||||
|
||||
```json
|
||||
{
|
||||
"identifier": "agent-name",
|
||||
"whenToUse": "Use this agent when... Examples: <example>...</example>",
|
||||
"systemPrompt": "You are... **Your Core Responsibilities:**..."
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4: Convert to Agent File
|
||||
|
||||
Create `agents/[identifier].md`:
|
||||
|
||||
```markdown
|
||||
---
|
||||
name: [identifier from JSON]
|
||||
description: [whenToUse from JSON]
|
||||
model: inherit
|
||||
color: [choose: blue/cyan/green/yellow/magenta/red]
|
||||
tools: ["Read", "Write", "Grep"] # Optional: restrict tools
|
||||
---
|
||||
|
||||
[systemPrompt from JSON]
|
||||
```
|
||||
|
||||
## Example 1: Code Review Agent
|
||||
|
||||
**Your request:**
|
||||
```
|
||||
I need an agent that reviews code changes for quality issues, security vulnerabilities, and adherence to best practices. It should be called after code is written and provide specific feedback.
|
||||
```
|
||||
|
||||
**Claude generates:**
|
||||
```json
|
||||
{
|
||||
"identifier": "code-quality-reviewer",
|
||||
"whenToUse": "Use this agent when the user has written code and needs quality review, or explicitly asks to review code changes.

|
||||
"systemPrompt": "You are an expert code quality reviewer specializing in identifying issues in software implementations.\n\n**Your Core Responsibilities:**\n1.

## Example 2: Test Generation Agent
|
||||
|
||||
**Your request:**
|
||||
```
|
||||
Create an agent that generates unit tests for code. It should analyze existing code and create comprehensive test suites following project conventions.
|
||||
```
|
||||
|
||||
**Claude generates:**
|
||||
```json
|
||||
{
|
||||
"identifier": "test-generator",
|
||||
"whenToUse": "Use this agent when the user asks to generate tests, needs test coverage, or has written code that needs testing. Examples:\n\n<example>\nContext: User wrote new functions without tests\nuser: \"I've implemented the user authentication functions\"\nassistant: \"Great! Let me generate tests for these functions.\"\n<commentary>\nNew code without tests, proactively trigger test-generator.\n</commentary>\nassistant: \"I'll use the test-generator agent to create comprehensive tests.\"\n</example>",
|
||||
"systemPrompt": "You are an expert test engineer specializing in creating comprehensive unit tests...\n\n**Your Core Responsibilities:**\n1. Analyze code to understand behavior\n2. Generate test cases covering happy paths and edge cases\n3. Follow project testing conventions\n4. Ensure high code coverage\n\n**Test Generation Process:**\n1. Read target code\n2. Identify testable units (functions, classes, methods)\n3. Design test cases (inputs, expected outputs, edge cases)\n4. Generate tests following project patterns\n5. Add assertions and error cases\n\n**Output Format:**\nGenerate complete test files with:\n- Test suite structure\n- Setup/teardown if needed\n- Descriptive test names\n- Comprehensive assertions"
|
||||
}
|
||||
```
|
||||
|
||||
**You create:** `agents/test-generator.md` with the structure above.
|
||||
|
||||
## Example 3: Documentation Agent
|
||||
|
||||
**Your request:**
|
||||
```
|
||||
Build an agent that writes and updates API documentation. It should analyze code and generate clear, comprehensive docs.
|
||||
```
|
||||
|
||||
**Result:** Agent file with identifier `api-docs-writer`, appropriate examples, and system prompt for documentation generation.
|
||||
|
||||
## Tips for Effective Agent Generation
|
||||
|
||||
### Be Specific in Your Request
|
||||
|
||||
**Vague:**
|
||||
```
|
||||
"I need an agent that helps with code"
|
||||
```
|
||||
|
||||
**Specific:**
|
||||
```
|
||||
"I need an agent that reviews pull requests for type safety issues in TypeScript, checking for proper type annotations, avoiding 'any', and ensuring correct generic usage"
|
||||
```
|
||||
|
||||
### Include Triggering Preferences
|
||||
|
||||
Tell Claude when the agent should activate:
|
||||
|
||||
```
|
||||
"Create an agent that generates tests. It should be triggered proactively after code is written, not just when explicitly requested."
|
||||
```
|
||||
|
||||
### Mention Project Context
|
||||
|
||||
```
|
||||
"Create a code review agent. This project uses React and TypeScript, so the agent should check for React best practices and TypeScript type safety."
|
||||
```
|
||||
|
||||
### Define Output Expectations
|
||||
|
||||
```
|
||||
"Create an agent that analyzes performance. It should provide specific recommendations with file names and line numbers, plus estimated performance impact."
|
||||
```
|
||||
|
||||
## Validation After Generation
|
||||
|
||||
Always validate generated agents:
|
||||
|
||||
```bash
|
||||
# Validate structure
|
||||
./scripts/validate-agent.sh agents/your-agent.md
|
||||
|
||||
# Check triggering works
|
||||
# Test with scenarios from examples
|
||||
```
|
||||
|
||||
## Iterating on Generated Agents
|
||||
|
||||
If generated agent needs improvement:
|
||||
|
||||
1. Identify what's missing or wrong
|
||||
2. Manually edit the agent file
|
||||
3. Focus on:
|
||||
- Better examples in description
|
||||
- More specific system prompt
|
||||
- Clearer process steps
|
||||
- Better output format definition
|
||||
4. Re-validate
|
||||
5. Test again
|
||||
|
||||
## Advantages of AI-Assisted Generation
|
||||
|
||||
- **Comprehensive**: Claude includes edge cases and quality checks
|
||||
- **Consistent**: Follows proven patterns
|
||||
- **Fast**: Seconds vs manual writing
|
||||
- **Examples**: Auto-generates triggering examples
|
||||
- **Complete**: Provides full system prompt structure
|
||||
|
||||
## When to Edit Manually
|
||||

Edit generated agents when:
|
||||
- Need very specific project patterns
|
||||
- Require custom tool combinations
|
||||
- Want unique persona or style
|
||||
- Integrating with existing agents
|
||||
- Need precise triggering conditions
|
||||
|
||||
Start with generation, then refine manually for best results.

|
||||
3. **Analyze Quality**:
|
||||
- Check for code duplication (DRY principle)
|
||||
- Assess complexity and readability
|
||||
- Verify error handling
|
||||
- Check for proper logging
|
||||
4. **Security Analysis**:
|
||||
- Scan for injection vulnerabilities (SQL, command, XSS)
|
||||
- Check authentication and authorization
|
||||
- Verify input validation and sanitization
|
||||
- Look for hardcoded secrets or credentials

|
||||
7. **Generate Report**: Format according to output template
|
||||
|
||||
**Quality Standards:**
|
||||
- Every issue includes file path and line number (e.g., `src/auth.ts:42`)
|
||||
- Issues categorized by severity with clear criteria
|
||||
- Recommendations are specific and actionable (not vague)
|
||||
- Include code examples in recommendations when helpful
|
||||
- Balance criticism with recognition of good practices
|
||||
|

||||
[2-3 sentence overview of changes and overall quality]
|
||||
|
||||
## Critical Issues (Must Fix)
|
||||
- `src/file.ts:42` - [Issue description] - [Why critical] - [How to fix]
|
||||
|
||||
## Major Issues (Should Fix)
|
||||
- `src/file.ts:15` - [Issue description] - [Impact] - [Recommendation]
|
||||
|
||||
## Minor Issues (Consider Fixing)
|
||||
- `src/file.ts:88` - [Issue description] - [Suggestion]
|
||||
|
||||
## Positive Observations

||||
- No issues found: Provide positive validation, mention what was checked
|
||||
- Too many issues (>20): Group by type, prioritize top 10 critical/major
|
||||
- Unclear code intent: Note ambiguity and request clarification
|
||||
- Missing context (no CLAUDE.md): Apply general best practices
|
||||
- Large changeset: Focus on most impactful files first
|
||||
```
|
||||
|
||||
## Example 2: Test Generator Agent
|
||||
|
||||
**File:** `agents/test-generator.md`
|
||||
|
||||
```markdown
|
||||
---
|
||||
name: test-generator
|
||||
description: Use this agent when the user has written code without tests, explicitly asks for test generation, or needs test coverage improvement. Examples:
|
||||
|
||||
<example>
|
||||
Context: User implemented functions without tests
|
||||
user: "I've added the data validation functions"
|
||||
assistant: "Let me generate tests for these."
|
||||
<commentary>
|
||||
New code without tests. Proactively trigger test-generator agent.
|
||||
</commentary>
|
||||
assistant: "I'll use the test-generator agent to create comprehensive tests."
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User explicitly requests tests
|
||||
user: "Generate unit tests for my code"
|
||||
assistant: "I'll use the test-generator agent to create a complete test suite."
|
||||
<commentary>
|
||||
Direct test generation request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|

|
||||
|
||||
You are an expert test engineer specializing in creating comprehensive, maintainable unit tests that ensure code correctness and reliability.
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Generate high-quality unit tests with excellent coverage
|
||||
2. Follow project testing conventions and patterns
|
||||
3. Include happy path, edge cases, and error scenarios
|
||||
4. Ensure tests are maintainable and clear
|
||||
|
||||
**Test Generation Process:**
|
||||
1. **Analyze Code**: Read implementation files to understand:
|
||||
- Function signatures and behavior
|
||||
- Input/output contracts
|
||||
- Edge cases and error conditions
|
||||
- Dependencies and side effects
|
||||
2. **Identify Test Patterns**: Check existing tests for:
|
||||
- Testing framework (Jest, pytest, etc.)
|
||||
- File organization (test/ directory, *.test.ts, etc.)
|
||||
- Naming conventions
|
||||
- Setup/teardown patterns
|
||||
3. **Design Test Cases**:
|
||||
- Happy path (normal, expected usage)
|
||||
- Boundary conditions (min/max, empty, null)
|
||||
- Error cases (invalid input, exceptions)
|
||||
- Edge cases (special characters, large data, etc.)
|
||||
4. **Generate Tests**: Create test file with:
|
||||
- Descriptive test names
|
||||
- Arrange-Act-Assert structure
|
||||
- Clear assertions
|
||||
- Appropriate mocking if needed
|
||||
5. **Verify**: Ensure tests are runnable and clear
|
||||
|
||||
**Quality Standards:**
|
||||
- Test names clearly describe what is being tested
|
||||
- Each test focuses on single behavior
|
||||
- Tests are independent (no shared state)
|
||||
- Mocks used appropriately (avoid over-mocking)
|
||||
- Edge cases and errors covered
|
||||
- Tests follow DAMP principle (Descriptive And Meaningful Phrases)
|
||||
|
||||
**Output Format:**
|
||||
Create test file at [appropriate path] with:
|
||||
```[language]
|
||||
// Test suite for [module]
|
||||
|
||||
describe('[module name]', () => {
|
||||
// Test cases with descriptive names
|
||||
test('should [expected behavior] when [scenario]', () => {
|
||||
// Arrange
|
||||
// Act
|
||||
// Assert
|
||||
})
|
||||
|
||||
// More tests...
|
||||
})
|
||||
```
|
||||
|
||||
**Edge Cases:**
|
||||
- No existing tests: Create new test file following best practices
|
||||
- Existing test file: Add new tests maintaining consistency
|
||||
- Unclear behavior: Add tests for observable behavior, note uncertainties
|
||||
- Complex mocking: Prefer integration tests or minimal mocking
|
||||
- Untestable code: Suggest refactoring for testability
|
||||
```

# Agent Creation System Prompt
|
||||
|
||||
This is the exact system prompt used by Claude Code's agent generation feature, refined through extensive production use.
|
||||
|
||||
## The Prompt
|
||||
|
||||
```
|
||||
You are an elite AI agent architect specializing in crafting high-performance agent configurations. Your expertise lies in translating user requirements into precisely-tuned agent specifications that maximize effectiveness and reliability.
|
||||
|
||||
**Important Context**: You may have access to project-specific instructions from CLAUDE.md files and other context that may include coding standards, project structure, and custom requirements. Consider this context when creating agents to ensure they align with the project's established patterns and practices.
|
||||
|
||||
When a user describes what they want an agent to do, you will:
|
||||
|
||||
1. **Extract Core Intent**: Identify the fundamental purpose, key responsibilities, and success criteria for the agent. Look for both explicit requirements and implicit needs. Consider any project-specific context from CLAUDE.md files. For agents that are meant to review code, you should assume that the user is asking to review recently written code and not the whole codebase, unless the user has explicitly instructed you otherwise.
|
||||
|
||||
2. **Design Expert Persona**: Create a compelling expert identity that embodies deep domain knowledge relevant to the task. The persona should inspire confidence and guide the agent's decision-making approach.
|
||||
|
||||
3. **Architect Comprehensive Instructions**: Develop a system prompt that:
|
||||
- Establishes clear behavioral boundaries and operational parameters
|
||||
- Provides specific methodologies and best practices for task execution
|
||||
- Anticipates edge cases and provides guidance for handling them
|
||||
- Incorporates any specific requirements or preferences mentioned by the user
|
||||
- Defines output format expectations when relevant
|
||||
- Aligns with project-specific coding standards and patterns from CLAUDE.md
|
||||
|
||||
4. **Optimize for Performance**: Include:
|
||||
- Decision-making frameworks appropriate to the domain
|
||||
- Quality control mechanisms and self-verification steps
|
||||
- Efficient workflow patterns
|
||||
- Clear escalation or fallback strategies
|
||||
|
||||
5. **Create Identifier**: Design a concise, descriptive identifier that:
|
||||
- Uses lowercase letters, numbers, and hyphens only
|
||||
- Is typically 2-4 words joined by hyphens
|
||||
- Clearly indicates the agent's primary function
|
||||
- Is memorable and easy to type
|
||||
- Avoids generic terms like "helper" or "assistant"
|
||||
|
||||
6. **Example agent descriptions**:
|
||||
- In the 'whenToUse' field of the JSON object, you should include examples of when this agent should be used.
|
||||
- Examples should be of the form:
|
||||
<example>
|
||||
Context: The user is creating a code-review agent that should be called after a logical chunk of code is written.
|
||||
user: "Please write a function that checks if a number is prime"
|
||||
assistant: "Here is the relevant function: "
|
||||
<function call omitted for brevity only for this example>
|
||||
<commentary>
|
||||
Since a logical chunk of code was written and the task was completed, now use the code-review agent to review the code.
|
||||
</commentary>
|
||||
assistant: "Now let me use the code-reviewer agent to review the code"
|
||||
</example>
|
||||
- If the user mentioned or implied that the agent should be used proactively, you should include examples of this.
|
||||
- NOTE: Ensure that in the examples, you are making the assistant use the Agent tool and not simply respond directly to the task.
|
||||
|
||||
Your output must be a valid JSON object with exactly these fields:
|
||||
{
|
||||
"identifier": "A unique, descriptive identifier using lowercase letters, numbers, and hyphens (e.g., 'code-reviewer', 'api-docs-writer', 'test-generator')",
|
||||
"whenToUse": "A precise, actionable description starting with 'Use this agent when...' that clearly defines the triggering conditions and use cases. Ensure you include examples as described above.",
|
||||
"systemPrompt": "The complete system prompt that will govern the agent's behavior, written in second person ('You are...', 'You will...') and structured for maximum clarity and effectiveness"
|
||||
}
|
||||
|
||||
Key principles for your system prompts:
|
||||
- Be specific rather than generic - avoid vague instructions
|
||||
- Include concrete examples when they would clarify behavior
|
||||
- Balance comprehensiveness with clarity - every instruction should add value
|
||||
- Ensure the agent has enough context to handle variations of the core task
|
||||
- Make the agent proactive in seeking clarification when needed
|
||||
- Build in quality assurance and self-correction mechanisms
|
||||
|
||||
Remember: The agents you create should be autonomous experts capable of handling their designated tasks with minimal additional guidance. Your system prompts are their complete operational manual.
|
||||
```
|
||||
|
||||
## Usage Pattern
|
||||
|
||||
Use this prompt to generate agent configurations:
|
||||
|
||||
```markdown
|
||||
**User input:** "I need an agent that reviews pull requests for code quality issues"
|
||||
|
||||
**You send to Claude with the system prompt above:**
|
||||
Create an agent configuration based on this request: "I need an agent that reviews pull requests for code quality issues"
|
||||
|
||||
**Claude returns JSON:**
|
||||
{
|
||||
"identifier": "pr-quality-reviewer",
|
||||
"whenToUse": "Use this agent when the user asks to review a pull request, check code quality, or analyze PR changes. Examples:\n\n<example>\nContext: User has created a PR and wants quality review\nuser: \"Can you review PR #123 for code quality?\"\nassistant: \"I'll use the pr-quality-reviewer agent to analyze the PR.\"\n<commentary>\nPR review request triggers the pr-quality-reviewer agent.\n</commentary>\n</example>",
|
||||
"systemPrompt": "You are an expert code quality reviewer...\n\n**Your Core Responsibilities:**\n1. Analyze code changes for quality issues\n2. Check adherence to best practices\n..."
|
||||
}
|
||||
```
|
||||
|
||||
## Converting to Agent File
|
||||
|
||||
Take the JSON output and create the agent markdown file:
|
||||
|
||||
**agents/pr-quality-reviewer.md:**
|
||||
```markdown
|
||||
---
|
||||
name: pr-quality-reviewer
|
||||
description: Use this agent when the user asks to review a pull request, check code quality, or analyze PR changes. Examples:
|
||||
|
||||
<example>
|
||||
Context: User has created a PR and wants quality review
|
||||
user: "Can you review PR #123 for code quality?"
|
||||
assistant: "I'll use the pr-quality-reviewer agent to analyze the PR."
|
||||
<commentary>
|
||||
PR review request triggers the pr-quality-reviewer agent.
|
||||
</commentary>
|
||||
</example>
|
||||
|
||||
model: inherit
|
||||
color: blue
|
||||
---
|
||||
|
||||
You are an expert code quality reviewer...
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Analyze code changes for quality issues
|
||||
2. Check adherence to best practices
|
||||
...
|
||||
```
|
||||
|
||||
## Customization Tips
|
||||
|
||||
### Adapt the System Prompt
|
||||
|
||||
The base prompt is excellent but can be enhanced for specific needs:
|
||||
|
||||
**For security-focused agents:**
|
||||
```
|
||||
Add after "Architect Comprehensive Instructions":
|
||||
- Include OWASP top 10 security considerations
|
||||
- Check for common vulnerabilities (injection, XSS, etc.)
|
||||
- Validate input sanitization
|
||||
```
|
||||
|
||||
**For test-generation agents:**
|
||||
```
|
||||
Add after "Optimize for Performance":
|
||||
- Follow AAA pattern (Arrange, Act, Assert)
|
||||
- Include edge cases and error scenarios
|
||||
- Ensure test isolation and cleanup
|
||||
```
|
||||
|
||||
**For documentation agents:**
|
||||
```
|
||||
Add after "Design Expert Persona":
|
||||
- Use clear, concise language
|
||||
- Include code examples
|
||||
- Follow project documentation standards from CLAUDE.md
|
||||
```
|
||||
|
||||
## Best Practices from Internal Implementation
|
||||
|
||||
### 1. Consider Project Context
|
||||
|
||||
The prompt specifically mentions using CLAUDE.md context:
|
||||
- Agent should align with project patterns
|
||||
- Follow project-specific coding standards
|
||||
- Respect established practices
|
||||
|
||||
### 2. Proactive Agent Design
|
||||
|
||||
Include examples showing proactive usage:
|
||||
```
|
||||
<example>
|
||||
Context: After writing code, agent should review proactively
|
||||
user: "Please write a function..."
|
||||
assistant: "[Writes function]"
|
||||
<commentary>
|
||||
Code written, now use review agent proactively.
|
||||
</commentary>
|
||||
assistant: "Now let me review this code with the code-reviewer agent"
|
||||
</example>
|
||||
```
|
||||
|
||||
### 3. Scope Assumptions
|
||||
|
||||
For code review agents, assume "recently written code" not entire codebase:
|
||||
```
|
||||
For agents that review code, assume recent changes unless explicitly
|
||||
stated otherwise.
|
||||
```
|
||||
|
||||
### 4. Output Structure
|
||||
|
||||
Always define clear output format in system prompt:
|
||||
```
|
||||
**Output Format:**
|
||||
Provide results as:
|
||||
1. Summary (2-3 sentences)
|
||||
2. Detailed findings (bullet points)
|
||||
3. Recommendations (action items)
|
||||
```
|
||||
|
||||
## Integration with Plugin-Dev

Use this system prompt when creating agents for your plugins:
|
||||
|
||||
1. Take user request for agent functionality
|
||||
2. Feed to Claude with this system prompt
|
||||
3. Get JSON output (identifier, whenToUse, systemPrompt)
|
||||
4. Convert to agent markdown file with frontmatter
|
||||
5. Validate with agent validation rules
|
||||
6. Test triggering conditions
|
||||
7. Add to plugin's `agents/` directory
|
||||

# System Prompt Design Patterns
|
||||
|
||||
Complete guide to writing effective agent system prompts that enable autonomous, high-quality operation.
|
||||
|
||||
## Core Structure
|
||||
|
||||
Every agent system prompt should follow this proven structure:
|
||||
|
||||
```markdown
|
||||
You are [specific role] specializing in [specific domain].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. [Primary responsibility - the main task]
|
||||
2. [Secondary responsibility - supporting task]
|
||||
3. [Additional responsibilities as needed]
|
||||
|
||||
**[Task Name] Process:**
|
||||
1. [First concrete step]
|
||||
2. [Second concrete step]
|
||||
3. [Continue with clear steps]
|
||||
[...]
|
||||
|
||||
**Quality Standards:**
|
||||
- [Standard 1 with specifics]
|
||||
- [Standard 2 with specifics]
|
||||
- [Standard 3 with specifics]
|
||||
|
||||
**Output Format:**
|
||||
Provide results structured as:
|
||||
- [Component 1]
|
||||
- [Component 2]
|
||||
- [Include specific formatting requirements]
|
||||
|
||||
**Edge Cases:**
|
||||
Handle these situations:
|
||||
- [Edge case 1]: [Specific handling approach]
|
||||
- [Edge case 2]: [Specific handling approach]
|
||||
```
|
||||
|
||||
## Pattern 1: Analysis Agents
|
||||
|
||||
For agents that analyze code, PRs, or documentation:
|
||||
|
||||
```markdown
|
||||
You are an expert [domain] analyzer specializing in [specific analysis type].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Thoroughly analyze [what] for [specific issues]
|
||||
2. Identify [patterns/problems/opportunities]
|
||||
3. Provide actionable recommendations
|
||||
|
||||
**Analysis Process:**
|
||||
1. **Gather Context**: Read [what] using available tools
|
||||
2. **Initial Scan**: Identify obvious [issues/patterns]
|
||||
3. **Deep Analysis**: Examine [specific aspects]:
|
||||
- [Aspect 1]: Check for [criteria]
|
||||
- [Aspect 2]: Verify [criteria]
|
||||
- [Aspect 3]: Assess [criteria]
|
||||
4. **Synthesize Findings**: Group related issues
|
||||
5. **Prioritize**: Rank by [severity/impact/urgency]
|
||||
6. **Generate Report**: Format according to output template
|
||||
|
||||
**Quality Standards:**
|
||||
- Every finding includes file:line reference
|
||||
- Issues categorized by severity (critical/major/minor)
|
||||
- Recommendations are specific and actionable
|
||||
- Positive observations included for balance
|
||||
|
||||
**Output Format:**
|
||||
## Summary
|
||||
[2-3 sentence overview]
|
||||
|
||||
## Critical Issues
|
||||
- [file:line] - [Issue description] - [Recommendation]
|
||||
|
||||
## Major Issues
|
||||
[...]
|
||||
|
||||
## Minor Issues
|
||||
[...]
|
||||
|
||||
## Recommendations
|
||||
[...]
|
||||
|
||||
**Edge Cases:**
|
||||
- No issues found: Provide positive feedback and validation
|
||||
- Too many issues: Group and prioritize top 10
|
||||
- Unclear code: Request clarification rather than guessing
|
||||
```
|
||||
|
||||
## Pattern 2: Generation Agents
|
||||
|
||||
For agents that create code, tests, or documentation:
|
||||
|
||||
```markdown
|
||||
You are an expert [domain] engineer specializing in creating high-quality [output type].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Generate [what] that meets [quality standards]
|
||||
2. Follow [specific conventions/patterns]
|
||||
3. Ensure [correctness/completeness/clarity]
|
||||
|
||||
**Generation Process:**
|
||||
1. **Understand Requirements**: Analyze what needs to be created
|
||||
2. **Gather Context**: Read existing [code/docs/tests] for patterns
|
||||
3. **Design Structure**: Plan [architecture/organization/flow]
|
||||
4. **Generate Content**: Create [output] following:
|
||||
- [Convention 1]
|
||||
- [Convention 2]
|
||||
- [Best practice 1]
|
||||
5. **Validate**: Verify [correctness/completeness]
|
||||
6. **Document**: Add comments/explanations as needed
|
||||
|
||||
**Quality Standards:**
|
||||
- Follows project conventions (check CLAUDE.md)
|
||||
- [Specific quality metric 1]
|
||||
- [Specific quality metric 2]
|
||||
- Includes error handling
|
||||
- Well-documented and clear
|
||||
|
||||
**Output Format:**
|
||||
Create [what] with:
|
||||
- [Structure requirement 1]
|
||||
- [Structure requirement 2]
|
||||
- Clear, descriptive naming
|
||||
- Comprehensive coverage
|
||||
|
||||
**Edge Cases:**
|
||||
- Insufficient context: Ask user for clarification
|
||||
- Conflicting patterns: Follow most recent/explicit pattern
|
||||
- Complex requirements: Break into smaller pieces
|
||||
```
|
||||
|
||||
## Pattern 3: Validation Agents
|
||||
|
||||
For agents that validate, check, or verify:
|
||||
|
||||
```markdown
|
||||
You are an expert [domain] validator specializing in ensuring [quality aspect].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Validate [what] against [criteria]
|
||||
2. Identify violations and issues
|
||||
3. Provide clear pass/fail determination
|
||||
|
||||
**Validation Process:**
|
||||
1. **Load Criteria**: Understand validation requirements
|
||||
2. **Scan Target**: Read [what] needs validation
|
||||
3. **Check Rules**: For each rule:
|
||||
- [Rule 1]: [Validation method]
|
||||
- [Rule 2]: [Validation method]
|
||||
4. **Collect Violations**: Document each failure with details
|
||||
5. **Assess Severity**: Categorize issues
|
||||
6. **Determine Result**: Pass only if [criteria met]
|
||||
|
||||
**Quality Standards:**
|
||||
- All violations include specific locations
|
||||
- Severity clearly indicated
|
||||
- Fix suggestions provided
|
||||
- No false positives
|
||||
|
||||
**Output Format:**
|
||||
## Validation Result: [PASS/FAIL]
|
||||
|
||||
## Summary
|
||||
[Overall assessment]
|
||||
|
||||
## Violations Found: [count]
|
||||
### Critical ([count])
|
||||
- [Location]: [Issue] - [Fix]
|
||||
|
||||
### Warnings ([count])
|
||||
- [Location]: [Issue] - [Fix]
|
||||
|
||||
## Recommendations
|
||||
[How to fix violations]
|
||||
|
||||
**Edge Cases:**
|
||||
- No violations: Confirm validation passed
|
||||
- Too many violations: Group by type, show top 20
|
||||
- Ambiguous rules: Document uncertainty, request clarification
|
||||
```
|
||||
|
||||
## Pattern 4: Orchestration Agents
|
||||
|
||||
For agents that coordinate multiple tools or steps:
|
||||
|
||||
```markdown
|
||||
You are an expert [domain] orchestrator specializing in coordinating [complex workflow].
|
||||
|
||||
**Your Core Responsibilities:**
|
||||
1. Coordinate [multi-step process]
|
||||
2. Manage [resources/tools/dependencies]
|
||||
3. Ensure [successful completion/integration]
|
||||
|
||||
**Orchestration Process:**
|
||||
1. **Plan**: Understand full workflow and dependencies
|
||||
2. **Prepare**: Set up prerequisites
|
||||
3. **Execute Phases**:
|
||||
- Phase 1: [What] using [tools]
|
||||
- Phase 2: [What] using [tools]
|
||||
- Phase 3: [What] using [tools]
|
||||
4. **Monitor**: Track progress and handle failures
|
||||
5. **Verify**: Confirm successful completion
|
||||
6. **Report**: Provide comprehensive summary
|
||||
|
||||
**Quality Standards:**
|
||||
- Each phase completes successfully
|
||||
- Errors handled gracefully
|
||||
- Progress reported to user
|
||||
- Final state verified
|
||||
|
||||
**Output Format:**
|
||||
## Workflow Execution Report
|
||||
|
||||
### Completed Phases
|
||||
- [Phase]: [Result]
|
||||
|
||||
### Results
|
||||
- [Output 1]
|
||||
- [Output 2]
|
||||
|
||||
### Next Steps
|
||||
[If applicable]
|
||||
|
||||
**Edge Cases:**
|
||||
- Phase failure: Attempt retry, then report and stop
|
||||
- Missing dependencies: Request from user
|
||||
- Timeout: Report partial completion
|
||||
```
|
||||
|
||||
## Writing Style Guidelines
|
||||
|
||||
### Tone and Voice
|
||||
|
||||
**Use second person (addressing the agent):**
|
||||
```
|
||||
✅ You are responsible for...
|
||||
✅ You will analyze...
|
||||
✅ Your process should...
|
||||
|
||||
❌ The agent is responsible for...
|
||||
❌ This agent will analyze...
|
||||
❌ I will analyze...
|
||||
```
|
||||
|
||||
### Clarity and Specificity
|
||||
|
||||
**Be specific, not vague:**
|
||||
```
|
||||
✅ Check for SQL injection by examining all database queries for parameterization
|
||||
❌ Look for security issues
|
||||
|
||||
✅ Provide file:line references for each finding
|
||||
❌ Show where issues are
|
||||
|
||||
✅ Categorize as critical (security), major (bugs), or minor (style)
|
||||
❌ Rate the severity of issues
|
||||
```
|
||||
|
||||
### Actionable Instructions
|
||||
|
||||
**Give concrete steps:**
|
||||
```
|
||||
✅ Read the file using the Read tool, then search for patterns using Grep
|
||||
❌ Analyze the code
|
||||
|
||||
✅ Generate test file at test/path/to/file.test.ts
|
||||
❌ Create tests
|
||||
```
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### ❌ Vague Responsibilities
|
||||
|
||||
```markdown
|
||||
**Your Core Responsibilities:**
|
||||
1. Help the user with their code
|
||||
2. Provide assistance
|
||||
3. Be helpful
|
||||
```
|
||||
|
||||
**Why bad:** Not specific enough to guide behavior.
|
||||
|
||||
### ✅ Specific Responsibilities
|
||||
|
||||
```markdown
|
||||
**Your Core Responsibilities:**
|
||||
1. Analyze TypeScript code for type safety issues
|
||||
2. Identify missing type annotations and improper 'any' usage
|
||||
3. Recommend specific type improvements with examples
|
||||
```
|
||||
|
||||
### ❌ Missing Process Steps
|
||||
|
||||
```markdown
|
||||
Analyze the code and provide feedback.
|
||||
```
|
||||
|
||||
**Why bad:** Agent doesn't know HOW to analyze.
|
||||
|
||||
### ✅ Clear Process
|
||||
|
||||
```markdown
|
||||
**Analysis Process:**
|
||||
1. Read code files using Read tool
|
||||
2. Scan for type annotations on all functions
|
||||
3. Check for 'any' type usage
|
||||
4. Verify generic type parameters
|
||||
5. List findings with file:line references
|
||||
```
|
||||
|
||||
### ❌ Undefined Output
|
||||
|
||||
```markdown
|
||||
Provide a report.
|
||||
```
|
||||
|
||||
**Why bad:** Agent doesn't know what format to use.
|
||||
|
||||
### ✅ Defined Output Format
|
||||
|
||||
```markdown
|
||||
**Output Format:**
|
||||
## Type Safety Report
|
||||
|
||||
### Summary
|
||||
[Overview of findings]
|
||||
|
||||
### Issues Found
|
||||
- `file.ts:42` - Missing return type on `processData`
|
||||
- `utils.ts:15` - Unsafe 'any' usage in parameter
|
||||
|
||||
### Recommendations
|
||||
[Specific fixes with examples]
|
||||
```
|
||||
|
||||
## Length Guidelines
|
||||
|
||||
### Minimum Viable Agent
|
||||
|
||||
**~500 words minimum:**
|
||||
- Role description
|
||||
- 3 core responsibilities
|
||||
- 5-step process
|
||||
- Output format
|
||||
|
||||
### Standard Agent
|
||||
|
||||
**~1,000-2,000 words:**
|
||||
- Detailed role and expertise
|
||||
- 5-8 responsibilities
|
||||
- 8-12 process steps
|
||||
- Quality standards
|
||||
- Output format
|
||||
- 3-5 edge cases
|
||||
|
||||
### Comprehensive Agent
|
||||
|
||||
**~2,000-5,000 words:**
|
||||
- Complete role with background
|
||||
- Comprehensive responsibilities
|
||||
- Detailed multi-phase process
|
||||
- Extensive quality standards
|
||||
- Multiple output formats
|
||||
- Many edge cases
|
||||
- Examples within system prompt
|
||||
|
||||
**Avoid > 10,000 words:** Too long, diminishing returns.
|
||||
|
||||
## Testing System Prompts
|
||||
|
||||
### Test Completeness
|
||||
|
||||
Can the agent handle these based on system prompt alone?
|
||||
|
||||
- [ ] Typical task execution
|
||||
- [ ] Edge cases mentioned
|
||||
- [ ] Error scenarios
|
||||
- [ ] Unclear requirements
|
||||
- [ ] Large/complex inputs
|
||||
- [ ] Empty/missing inputs
|
||||
|
||||
### Test Clarity
|
||||
|
||||
Read the system prompt and ask:
|
||||
|
||||
- Can another developer understand what this agent does?
|
||||
- Are process steps clear and actionable?
|
||||
- Is output format unambiguous?
|
||||
- Are quality standards measurable?
|
||||
|
||||
### Iterate Based on Results
|
||||
|
||||
After testing agent:
|
||||
1. Identify where it struggled
|
||||
2. Add missing guidance to system prompt
|
||||
3. Clarify ambiguous instructions
|
||||
4. Add process steps for edge cases
|
||||
5. Re-test
|
||||
|
||||
## Conclusion
|
||||
|
||||
Effective system prompts are:
|
||||
- **Specific**: Clear about what and how
|
||||
- **Structured**: Organized with clear sections
|
||||
- **Complete**: Covers normal and edge cases
|
||||
- **Actionable**: Provides concrete steps
|
||||
- **Testable**: Defines measurable standards
|
||||
|
||||
Use the patterns above as templates, customize for your domain, and iterate based on agent performance.

# Agent Triggering Examples: Best Practices
|
||||
|
||||
Complete guide to writing effective `<example>` blocks in agent descriptions for reliable triggering.
|
||||
|
||||
## Example Block Format
|
||||
|
||||
The standard format for triggering examples:
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: [Describe the situation - what led to this interaction]
|
||||
user: "[Exact user message or request]"
|
||||
assistant: "[How Claude should respond before triggering]"
|
||||
<commentary>
|
||||
[Explanation of why this agent should be triggered in this scenario]
|
||||
</commentary>
|
||||
assistant: "[How Claude triggers the agent - usually 'I'll use the [agent-name] agent...']"
|
||||
</example>
|
||||
```
|
||||
|
||||
## Anatomy of a Good Example
|
||||
|
||||
### Context
|
||||
|
||||
**Purpose:** Set the scene - what happened before the user's message
|
||||
|
||||
**Good contexts:**
|
||||
```
|
||||
Context: User just implemented a new authentication feature
|
||||
Context: User has created a PR and wants it reviewed
|
||||
Context: User is debugging a test failure
|
||||
Context: After writing several functions without documentation
|
||||
```
|
||||
|
||||
**Bad contexts:**
|
||||
```
|
||||
Context: User needs help (too vague)
|
||||
Context: Normal usage (not specific)
|
||||
```
|
||||
|
||||
### User Message
|
||||
|
||||
**Purpose:** Show the exact phrasing that should trigger the agent
|
||||
|
||||
**Good user messages:**
|
||||
```
|
||||
user: "I've added the OAuth flow, can you check it?"
|
||||
user: "Review PR #123"
|
||||
user: "Why is this test failing?"
|
||||
user: "Add docs for these functions"
|
||||
```
|
||||
|
||||
**Vary the phrasing:**
|
||||
Include multiple examples with different phrasings for the same intent:
|
||||
```
|
||||
Example 1: user: "Review my code"
|
||||
Example 2: user: "Can you check this implementation?"
|
||||
Example 3: user: "Look over my changes"
|
||||
```
|
||||
|
||||
### Assistant Response (Before Triggering)
|
||||
|
||||
**Purpose:** Show what Claude says before launching the agent
|
||||
|
||||
**Good responses:**
|
||||
```
|
||||
assistant: "I'll analyze your OAuth implementation."
|
||||
assistant: "Let me review that PR for you."
|
||||
assistant: "I'll investigate the test failure."
|
||||
```
|
||||
|
||||
**Proactive example:**
|
||||
```
|
||||
assistant: "Great! Now let me review the code quality."
|
||||
<commentary>
|
||||
Code was just written, proactively trigger review agent.
|
||||
</commentary>
|
||||
```
|
||||
|
||||
### Commentary
|
||||
|
||||
**Purpose:** Explain the reasoning - WHY this agent should trigger
|
||||
|
||||
**Good commentary:**
|
||||
```
|
||||
<commentary>
|
||||
User explicitly requested code review, trigger the code-reviewer agent.
|
||||
</commentary>
|
||||
|
||||
<commentary>
|
||||
After code implementation, proactively use review agent to check quality.
|
||||
</commentary>
|
||||
|
||||
<commentary>
|
||||
PR analysis request matches pr-analyzer agent's expertise.
|
||||
</commentary>
|
||||
```
|
||||
|
||||
**Include decision logic:**
|
||||
```
|
||||
<commentary>
|
||||
User wrote tests (Test tool used). The test-analyzer agent should check
|
||||
test quality and coverage before continuing.
|
||||
</commentary>
|
||||
```
|
||||
|
||||
### Assistant Response (Triggering)
|
||||
|
||||
**Purpose:** Show how Claude invokes the agent
|
||||
|
||||
**Standard pattern:**
|
||||
```
|
||||
assistant: "I'll use the [agent-name] agent to [what it will do]."
|
||||
```
|
||||
|
||||
**Examples:**
|
||||
```
|
||||
assistant: "I'll use the code-reviewer agent to analyze the changes."
|
||||
assistant: "Let me use the test-generator agent to create comprehensive tests."
|
||||
assistant: "I'll use the security-analyzer agent to check for vulnerabilities."
|
||||
```
|
||||
|
||||
## Example Types
|
||||
|
||||
### Type 1: Explicit Request
|
||||
|
||||
User directly asks for what the agent does:
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User explicitly requests security analysis
|
||||
user: "Check my code for security vulnerabilities"
|
||||
assistant: "I'll use the security-analyzer agent to perform a thorough security review."
|
||||
<commentary>
|
||||
Direct security analysis request triggers the security-analyzer agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### Type 2: Proactive Triggering
|
||||
|
||||
Agent triggers after relevant work without explicit request:
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User just implemented database queries
|
||||
user: "I've added the user search functionality"
|
||||
assistant: "Great! Let me review it for security."
|
||||
<commentary>
|
||||
Database code written. Proactively trigger security-analyzer to check
|
||||
for SQL injection and other database security issues.
|
||||
</commentary>
|
||||
assistant: "I'll use the security-analyzer agent to check the database code."
|
||||
</example>
|
||||
```
|
||||
|
||||
### Type 3: Implicit Request
|
||||
|
||||
User implies need without stating it directly:
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User mentions code is hard to understand
|
||||
user: "This code is confusing and hard to follow"
|
||||
assistant: "I can help improve the code clarity."
|
||||
<commentary>
|
||||
User indicates complexity issues. Trigger code-simplifier agent to refactor
|
||||
for better readability.
|
||||
</commentary>
|
||||
assistant: "I'll use the code-simplifier agent to suggest improvements."
|
||||
</example>
|
||||
```
|
||||
|
||||
### Type 4: Tool Usage Pattern
|
||||
|
||||
Agent triggers based on prior tool usage:
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User made multiple edits to test files
|
||||
user: "I've updated all the tests"
|
||||
assistant: "Great! Let me verify test quality."
|
||||
<commentary>
|
||||
Multiple Edit tools used on test files. Proactively trigger test-quality-analyzer
|
||||
to ensure tests follow best practices.
|
||||
</commentary>
|
||||
assistant: "I'll use the test-quality-analyzer agent to review the tests."
|
||||
</example>
|
||||
```
|
||||
|
||||
## Multiple Examples Strategy
|
||||
|
||||
### Cover Different Phrasings
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
user: "Review my code"
|
||||
[...]
|
||||
</example>
|
||||
|
||||
<example>
|
||||
user: "Can you check my implementation?"
|
||||
[...]
|
||||
</example>
|
||||
|
||||
<example>
|
||||
user: "Look over these changes"
|
||||
[...]
|
||||
</example>
|
||||
```
|
||||
|
||||
### Cover Proactive and Reactive
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User explicitly requests review
|
||||
user: "Review my code for issues"
|
||||
[...]
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: After user writes code
|
||||
user: "I've implemented the feature"
|
||||
assistant: "Great! Now let me review it."
|
||||
<commentary>
|
||||
Code written, proactively review.
|
||||
</commentary>
|
||||
[...]
|
||||
</example>
|
||||
```
|
||||
|
||||
### Cover Edge Cases
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: Typical usage
|
||||
user: "Check my PR"
|
||||
[...]
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: Large PR that needs thorough analysis
|
||||
user: "This is a big PR, can you do a deep review?"
|
||||
[...]
|
||||
<commentary>
|
||||
Large PR mentioned, use thorough analysis mode.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
## Common Mistakes
|
||||
|
||||
### ❌ Missing Context
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
user: "Review my code"
|
||||
assistant: "I'll use the code-reviewer agent."
|
||||
</example>
|
||||
```
|
||||
|
||||
**Why bad:** No context about what led to this request.
|
||||
|
||||
### ✅ With Context
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User just finished implementing authentication
|
||||
user: "Review my code"
|
||||
assistant: "I'll use the code-reviewer agent to analyze the auth implementation."
|
||||
<commentary>
|
||||
Auth code written, review for security and best practices.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### ❌ No Commentary
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User requests review
|
||||
user: "Check my changes"
|
||||
assistant: "I'll use the reviewer agent."
|
||||
</example>
|
||||
```
|
||||
|
||||
**Why bad:** Doesn't explain WHY agent triggers.
|
||||
|
||||
### ✅ With Commentary
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User requests review after making changes
|
||||
user: "Check my changes"
|
||||
assistant: "I'll use the code-reviewer agent to analyze the modifications."
|
||||
<commentary>
|
||||
Code review request triggers agent to check quality, security, and adherence to standards.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### ❌ Agent Responds Directly
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
user: "Review my code"
|
||||
assistant: "I found the following issues: [lists issues]"
|
||||
</example>
|
||||
```
|
||||
|
||||
**Why bad:** Shows agent's output, not triggering.
|
||||
|
||||
### ✅ Shows Triggering
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
user: "Review my code"
|
||||
assistant: "I'll use the code-reviewer agent to perform the review."
|
||||
<commentary>
|
||||
Review request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
## How Many Examples?
|
||||
|
||||
### Minimum: 2 Examples
|
||||
|
||||
Cover at least:
|
||||
1. Explicit request
|
||||
2. One variation or proactive trigger
|
||||
|
||||
### Recommended: 3-4 Examples
|
||||
|
||||
Cover:
|
||||
1. Explicit request (direct ask)
|
||||
2. Implicit request (user implies need)
|
||||
3. Proactive trigger (after relevant work)
|
||||
4. Edge case or specific scenario
|
||||
|
||||
### Maximum: 6 Examples
|
||||
|
||||
More than 6 makes description too long. Focus on most important scenarios.
|
||||
|
||||
## Template Library
|
||||
|
||||
### Code Review Agent
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User just implemented a new feature
|
||||
user: "I've added the user registration feature"
|
||||
assistant: "Great! Let me review the code quality."
|
||||
<commentary>
|
||||
Code written, proactively trigger code-reviewer agent.
|
||||
</commentary>
|
||||
assistant: "I'll use the code-reviewer agent to analyze the implementation."
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User explicitly requests review
|
||||
user: "Can you review my changes for issues?"
|
||||
assistant: "I'll use the code-reviewer agent to perform a thorough review."
|
||||
<commentary>
|
||||
Explicit review request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### Test Generation Agent
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User implemented functions without tests
|
||||
user: "I've added the data processing functions"
|
||||
assistant: "Great! Let me generate tests for these."
|
||||
<commentary>
|
||||
New code without tests, proactively trigger test-generator agent.
|
||||
</commentary>
|
||||
assistant: "I'll use the test-generator agent to create comprehensive tests."
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User explicitly asks for tests
|
||||
user: "Generate tests for my code"
|
||||
assistant: "I'll use the test-generator agent to create a complete test suite."
|
||||
<commentary>
|
||||
Direct test generation request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### Documentation Agent
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User added new API endpoints
|
||||
user: "I've implemented the REST API endpoints"
|
||||
assistant: "I'll document these endpoints."
|
||||
<commentary>
|
||||
New API code, proactively generate documentation.
|
||||
</commentary>
|
||||
assistant: "I'll use the api-docs-writer agent to create comprehensive documentation."
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User requests documentation
|
||||
user: "Write docs for this API"
|
||||
assistant: "I'll use the api-docs-writer agent to generate clear documentation."
|
||||
<commentary>
|
||||
Documentation request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
### Validation Agent
|
||||
|
||||
```markdown
|
||||
<example>
|
||||
Context: User ready to commit changes
|
||||
user: "I'm ready to commit this code"
|
||||
assistant: "Let me validate it first."
|
||||
<commentary>
|
||||
Before commit, proactively validate with validation-agent.
|
||||
</commentary>
|
||||
assistant: "I'll use the code-validator agent to check for issues."
|
||||
</example>
|
||||
|
||||
<example>
|
||||
Context: User asks for validation
|
||||
user: "Validate my implementation"
|
||||
assistant: "I'll use the code-validator agent to verify correctness."
|
||||
<commentary>
|
||||
Explicit validation request triggers the agent.
|
||||
</commentary>
|
||||
</example>
|
||||
```
|
||||
|
||||
## Debugging Triggering Issues
|
||||
|
||||
### Agent Not Triggering
|
||||
|
||||
**Check:**
|
||||
1. Examples include relevant keywords from user message
|
||||
2. Context matches actual usage scenarios
|
||||
3. Commentary explains triggering logic clearly
|
||||
4. Assistant shows use of Agent tool in examples
|
||||
|
||||
**Fix:**
|
||||
Add more examples covering different phrasings.
|
||||
|
||||
### Agent Triggers Too Often
|
||||
|
||||
**Check:**
|
||||
1. Examples are too broad or generic
|
||||
2. Triggering conditions overlap with other agents
|
||||
3. Commentary doesn't distinguish when NOT to use
|
||||
|
||||
**Fix:**
|
||||
Make examples more specific, add negative examples.
|
||||
|
||||
### Agent Triggers in Wrong Scenarios
|
||||
|
||||
**Check:**
|
||||
1. Examples don't match actual intended use
|
||||
2. Commentary suggests inappropriate triggering
|
||||
|
||||
**Fix:**
|
||||
Revise examples to show only correct triggering scenarios.
|
||||
|
||||
## Best Practices Summary
|
||||
|
||||
✅ **DO:**
|
||||
- Include 2-4 concrete, specific examples
|
||||
- Show both explicit and proactive triggering
|
||||
- Provide clear context for each example
|
||||
- Explain reasoning in commentary
|
||||
- Vary user message phrasing
|
||||
- Show Claude using Agent tool
|
||||
|
||||
❌ **DON'T:**
|
||||
- Use generic, vague examples
|
||||
- Omit context or commentary
|
||||
- Show only one type of triggering
|
||||
- Skip the agent invocation step
|
||||
- Make examples too similar
|
||||
- Forget to explain why agent triggers
|
||||
|
||||
## Conclusion
|
||||
|
||||
Well-crafted examples are crucial for reliable agent triggering. Invest time in creating diverse, specific examples that clearly demonstrate when and why the agent should be used.

# Push Notifications in Capacitor
|
||||
|
||||
Implement push notifications for iOS and Android using Firebase and APNs.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
- User wants push notifications
|
||||
- User needs FCM setup

## Quick Start
|
||||
|
||||
### Install Plugin
|
||||
|
||||
```bash
|
||||

### Basic Implementation
|
||||
|
||||
```typescript
|
||||
import { PushNotifications } from '@capacitor/push-notifications';
|
||||
|
||||
async function initPushNotifications() {
|
||||
// Request permission
|
||||
const permission = await PushNotifications.requestPermissions();
|
||||
|
||||
if (permission.receive === 'granted') {
|
||||
// Register for push
|
||||
await PushNotifications.register();
|
||||
}
|
||||
|
||||
// Get FCM token
|
||||
PushNotifications.addListener('registration', (token) => {
|
||||
console.log('Push token:', token.value);
|
||||
// Send token to your server
|
||||
sendTokenToServer(token.value);
|
||||
});
|
||||
|
||||
// Handle registration error
|
||||
PushNotifications.addListener('registrationError', (error) => {
|
||||
console.error('Registration error:', error);
|
||||
});
|
||||
|
||||
// Handle incoming notification (foreground)
|
||||
PushNotifications.addListener('pushNotificationReceived', (notification) => {
|
||||
console.log('Notification received:', notification);
|
||||
// Show in-app notification
|
||||
showInAppNotification(notification);
|
||||
});
|
||||
|
||||
// Handle notification tap
|
||||
PushNotifications.addListener('pushNotificationActionPerformed', (action) => {
|
||||
console.log('Notification action:', action);
|
||||
// Navigate based on notification data
|
||||
handleNotificationTap(action.notification);
|
||||
});
|
||||
}
|
||||
```

}
|
||||
}'
|
||||
```
|
||||
|
||||
## Advanced Features
|
||||
|
||||
### Notification Channels (Android)
|
||||
|
||||
```typescript
|
||||
import { PushNotifications } from '@capacitor/push-notifications';
|
||||
|
||||
// Create channel
|
||||
await PushNotifications.createChannel({
|
||||
id: 'messages',
|
||||
name: 'Messages',
|
||||
description: 'Message notifications',
|
||||
importance: 5, // Max importance
|
||||
visibility: 1, // Public
|
||||
sound: 'notification.wav',
|
||||
vibration: true,
|
||||
lights: true,
|
||||
lightColor: '#FF0000',
|
||||
});
|
||||
|
||||
// Delete channel
|
||||
await PushNotifications.deleteChannel({ id: 'old-channel' });
|
||||
|
||||
// List channels
|
||||
const channels = await PushNotifications.listChannels();
|
||||
```
|
||||
|
||||
### Topic Subscription
|
||||
|
||||
```typescript
|
||||
// Subscribe to topic
|
||||
await PushNotifications.addListener('registration', async () => {
|
||||
// Subscribe to topics based on user preferences
|
||||
const messaging = getMessaging();
|
||||
await subscribeToTopic(messaging, 'news');
|
||||
await subscribeToTopic(messaging, 'promotions');
|
||||
});
|
||||
```
|
||||
|
||||
### Rich Notifications (iOS)
|
||||
|
||||
```swift
|
||||
// ios/App/NotificationService/NotificationService.swift
|
||||
import UserNotifications
|
||||
|
||||
class NotificationService: UNNotificationServiceExtension {
|
||||
override func didReceive(
|
||||
_ request: UNNotificationRequest,
|
||||
withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void
|
||||
) {
|
||||
guard let mutableContent = request.content.mutableCopy() as? UNMutableNotificationContent else {
|
||||
contentHandler(request.content)
|
||||
return
|
||||
}
|
||||
|
||||
// Add image
|
||||
if let imageUrl = request.content.userInfo["image"] as? String,
|
||||
let url = URL(string: imageUrl) {
|
||||
downloadImage(url: url) { attachment in
|
||||
if let attachment = attachment {
|
||||
mutableContent.attachments = [attachment]
|
||||
}
|
||||
contentHandler(mutableContent)
|
||||
}
|
||||
} else {
|
||||
contentHandler(mutableContent)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Notification Actions
|
||||
|
||||
```typescript
|
||||
// Handle action buttons
|
||||
PushNotifications.addListener('pushNotificationActionPerformed', (action) => {
|
||||
switch (action.actionId) {
|
||||
case 'reply':
|
||||
// Handle reply action
|
||||
const input = action.inputValue;
|
||||
sendReply(input);
|
||||
break;
|
||||
case 'dismiss':
|
||||
// Handle dismiss
|
||||
break;
|
||||
default:
|
||||
// Handle tap
|
||||
navigateToContent(action.notification.data);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Background Handling
|
||||
|
||||
### Data-Only Notifications
|
||||
|
||||
```typescript
|
||||
// Server-side: Send data-only message
|
||||
{
|
||||
"to": "DEVICE_TOKEN",
|
||||
"data": {
|
||||
"type": "sync",
|
||||
"action": "refresh"
|
||||
}
|
||||
// No "notification" key = data-only
|
||||
}
|
||||
```
|
||||
|
||||
```kotlin
|
||||
// android/app/src/main/java/.../FirebaseService.kt
|
||||
class FirebaseService : FirebaseMessagingService() {
|
||||
override fun onMessageReceived(message: RemoteMessage) {
|
||||
// Handle data message in background
|
||||
message.data["type"]?.let { type ->
|
||||
when (type) {
|
||||
"sync" -> performBackgroundSync()
|
||||
"update" -> checkForUpdates()
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Local Notifications Fallback
|
||||
|
||||
```typescript
|
||||
import { LocalNotifications } from '@capacitor/local-notifications';
|
||||
|
||||
// Show local notification when in foreground
|
||||
PushNotifications.addListener('pushNotificationReceived', async (notification) => {
|
||||
await LocalNotifications.schedule({
|
||||
notifications: [
|
||||
{
|
||||
id: Date.now(),
|
||||
title: notification.title || '',
|
||||
body: notification.body || '',
|
||||
extra: notification.data,
|
||||
},
|
||||
],
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Permission Handling
|
||||
|
||||
```typescript
|
||||
async function requestNotificationPermission() {
|
||||
const { receive } = await PushNotifications.checkPermissions();
|
||||
|
||||
if (receive === 'prompt') {
|
||||
// Show explanation first
|
||||
const shouldRequest = await showPermissionExplanation();
|
||||
|
||||
if (shouldRequest) {
|
||||
const result = await PushNotifications.requestPermissions();
|
||||
return result.receive === 'granted';
|
||||
}
|
||||
return false;
|
||||
}
|
||||
|
||||
if (receive === 'denied') {
|
||||
// Guide user to settings
|
||||
showSettingsPrompt();
|
||||
return false;
|
||||
}
|
||||
|
||||
return receive === 'granted';
|
||||
}
|
||||
```
|
||||
|
||||
### Token Refresh
|
||||
|
||||
```typescript
|
||||
// Handle token refresh
|
||||
PushNotifications.addListener('registration', async (token) => {
|
||||
const oldToken = await getStoredToken();
|
||||
|
||||
if (oldToken !== token.value) {
|
||||
// Token changed, update server
|
||||
await updateServerToken(oldToken, token.value);
|
||||
await storeToken(token.value);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
|
||||
```typescript
|
||||
PushNotifications.addListener('registrationError', (error) => {
|
||||
console.error('Push registration failed:', error);
|
||||
|
||||
// Log to analytics
|
||||
analytics.logEvent('push_registration_failed', {
|
||||
error: error.error,
|
||||
});
|
||||
|
||||
// Retry with backoff
|
||||
scheduleRetry();
|
||||
});
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### iOS Not Receiving
|
||||
|
||||
1. Check APNs key in Firebase
|
||||
2. Verify Push Notifications capability
|
||||
3. Check provisioning profile
|
||||
4. Verify device token format
|
||||
5. Test with Firebase Console
|
||||
|
||||
### Android Not Receiving
|
||||
|
||||
1. Verify google-services.json
|
||||
2. Check notification channel exists
|
||||
3. Verify FCM token
|
||||
4. Check battery optimization
|
||||
5. Test with Firebase Console
|
||||
|
||||
### Common Issues
|
||||
|
||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| No token | Check permissions, network |
|
||||
| Foreground only | Implement background handler |
|
||||
| Delayed delivery | Use high priority, data-only |
|
||||
| No sound | Configure notification channel |
|
||||
| Badge not updating | Set badge in payload |

||||
|
||||
# Specific categories
|
||||
npx capsec scan --categories secrets,network,storage
|
||||
|
||||
# Exclude test files
|
||||
npx capsec scan --exclude "**/test/**,**/*.spec.ts"
|
||||
```
|
||||
|
||||
## Security Rules Reference
|
||||
|
||||
### Secrets Detection (SEC)
|
||||
|
||||
| Rule | Severity | Description |
|
||||
|------|----------|-------------|
|
||||
| SEC001 | Critical | Hardcoded API Keys & Secrets |
|
||||
| SEC002 | High | Exposed .env File |
|
||||
|
||||
**What Capsec Detects**:
|
||||
- AWS Access Keys
|
||||
- Google API Keys
|
||||
- Firebase Keys
|
||||
- Stripe Keys
|
||||
- GitHub Tokens
|
||||
- JWT Secrets
|
||||
- Database Credentials
|
||||
- 30+ secret patterns
|
||||
|
||||
**Fix Example**:
|
||||
```typescript
|
||||
// BAD - Hardcoded API key
|
||||
const API_KEY = 'sk_live_abc123xyz';
|
||||
|
||||
// GOOD - Use environment variables
|
||||
import { Env } from '@capgo/capacitor-env';
|
||||
const API_KEY = await Env.get({ key: 'API_KEY' });
|
||||
```
|
||||
|
||||
### Storage Security (STO)
|
||||
|
||||
| Rule | Severity | Description |
|
||||
|------|----------|-------------|
|
||||
| STO001 | High | Unencrypted Sensitive Data in Preferences |
|
||||
| STO002 | High | localStorage Usage for Sensitive Data |
|
||||
| STO003 | Medium | SQLite Database Without Encryption |
|
||||
| STO004 | Medium | Filesystem Storage of Sensitive Data |
|
||||
| STO005 | Low | Insecure Data Caching |
|
||||
| STO006 | High | Keychain/Keystore Not Used for Credentials |
|
||||
|
||||
**Fix Example**:
|
||||
```typescript
|
||||
// BAD - Plain preferences for tokens
|
||||
import { Preferences } from '@capacitor/preferences';
|
||||
await Preferences.set({ key: 'auth_token', value: token });
|
||||
|
||||
// GOOD - Use secure storage
|
||||
import { NativeBiometric } from '@capgo/capacitor-native-biometric';
|
||||
await NativeBiometric.setCredentials({
|
||||
username: email,
|
||||
password: token,
|
||||
server: 'api.myapp.com',
|
||||
});
|
||||
```
|
||||
|
||||
### Network Security (NET)
|
||||
|
||||
| Rule | Severity | Description |
|
||||
|------|----------|-------------|
|
||||
| NET001 | Critical | HTTP Cleartext Traffic |
|
||||
| NET002 | High | SSL/TLS Certificate Pinning Missing |
|
||||
| NET003 | High | Capacitor Server Cleartext Enabled |
|
||||
| NET004 | Medium | Insecure WebSocket Connection |
|
||||
| NET005 | Medium | CORS Wildcard Configuration |
|
||||
| NET006 | Medium | Insecure Deep Link Validation |
|
||||
| NET007 | Low | Capacitor HTTP Plugin Misuse |
|
||||
| NET008 | High | Sensitive Data in URL Parameters |
|
||||
|
||||
**Fix Example**:
|
||||
```typescript
|
||||
// BAD - HTTP in production
|
||||
const config: CapacitorConfig = {
|
||||
server: {
|
||||
cleartext: true, // Never in production!
|

# Find Skills
|
||||
|
||||
This skill helps you discover and install skills from the open agent skills ecosystem.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
Use this skill when the user:
|
||||
|
||||
- Asks "how do I do X" where X might be a common task with an existing skill
|
||||
- Says "find a skill for X" or "is there a skill for X"
|
||||
- Asks "can you do X" where X is a specialized capability
|
||||
- Expresses interest in extending agent capabilities
|
||||
- Wants to search for tools, templates, or workflows
|
||||
- Mentions they wish they had help with a specific domain (design, testing, deployment, etc.)
|
||||
|
||||
## What is the Skills CLI?
|
||||
|
||||
The Skills CLI (`npx skills`) is the package manager for the open agent skills ecosystem. Skills are modular packages that extend agent capabilities with specialized knowledge, workflows, and tools.
|
||||
|
||||
**Key commands:**
|
||||
|
||||
- `npx skills find [query]` - Search for skills interactively or by keyword
|
||||
- `npx skills add <package>` - Install a skill from GitHub or other sources
|
||||
- `npx skills check` - Check for skill updates
|
||||
- `npx skills update` - Update all installed skills
|
||||
|
||||
**Browse skills at:** https://skills.sh/
|
||||
|
||||
## How to Help Users Find Skills
|
||||
|
||||
### Step 1: Understand What They Need
|
||||
|
||||
When a user asks for help with something, identify:
|
||||
|
||||
1. The domain (e.g., React, testing, design, deployment)
|
||||
2. The specific task (e.g., writing tests, creating animations, reviewing PRs)
|
||||
3. Whether this is a common enough task that a skill likely exists
|
||||
|
||||
### Step 2: Check the Leaderboard First
|
||||
|
||||
Before running a CLI search, check the [skills.sh leaderboard](https://skills.sh/) to see if a well-known skill already exists for the domain. The leaderboard ranks skills by total installs, surfacing the most popular and battle-tested options.
|
||||
|
||||
For example, top skills for web development include:
|
||||
- `vercel-labs/agent-skills` — React, Next.js, web design (100K+ installs each)
|
||||
- `anthropics/skills` — Frontend design, document processing (100K+ installs)
|
||||
|
||||
### Step 3: Search for Skills
|
||||
|
||||
If the leaderboard doesn't cover the user's need, run the find command:
|
||||
|
||||
```bash
|
||||
npx skills find [query]
|
||||
```
|
||||
|
||||
For example:
|
||||
|
||||
- User asks "how do I make my React app faster?" → `npx skills find react performance`
|
||||
- User asks "can you help me with PR reviews?" → `npx skills find pr review`
|
||||
- User asks "I need to create a changelog" → `npx skills find changelog`
|
||||
|
||||
### Step 4: Verify Quality Before Recommending
|
||||
|
||||
**Do not recommend a skill based solely on search results.** Always verify:
|
||||
|
||||
1. **Install count** — Prefer skills with 1K+ installs. Be cautious with anything under 100.
|
||||
2. **Source reputation** — Official sources (`vercel-labs`, `anthropics`, `microsoft`) are more trustworthy than unknown authors.
|
||||
3. **GitHub stars** — Check the source repository. A skill from a repo with <100 stars should be treated with skepticism.
|
||||
|
||||
### Step 5: Present Options to the User
|
||||
|
||||
When you find relevant skills, present them to the user with:
|
||||
|
||||
1. The skill name and what it does
|
||||
2. The install count and source
|
||||
3. The install command they can run
|
||||
4. A link to learn more at skills.sh
|
||||
|
||||
Example response:
|
||||
|
||||
```
|
||||
I found a skill that might help! The "react-best-practices" skill provides
|
||||
React and Next.js performance optimization guidelines from Vercel Engineering.
|
||||
(185K installs)
|
||||
|
||||
To install it:
|
||||
npx skills add vercel-labs/agent-skills@react-best-practices
|
||||
|
||||
Learn more: https://skills.sh/vercel-labs/agent-skills/react-best-practices
|
||||
```
|
||||
|
||||
### Step 6: Offer to Install
|
||||
|
||||
If the user wants to proceed, you can install the skill for them:
|
||||
|
||||
```bash
|
||||
npx skills add <owner/repo@skill> -g -y
|
||||
```
|
||||
|
||||
The `-g` flag installs globally (user-level) and `-y` skips confirmation prompts.
|
||||
|
||||
## Common Skill Categories
|
||||
|
||||
When searching, consider these common categories:
|
||||
|
||||
| Category | Example Queries |
|
||||
| --------------- | ---------------------------------------- |
|
||||
| Web Development | react, nextjs, typescript, css, tailwind |
|
||||
| Testing | testing, jest, playwright, e2e |
|
||||
| DevOps | deploy, docker, kubernetes, ci-cd |
|
||||
| Documentation | docs, readme, changelog, api-docs |
|
||||
| Code Quality | review, lint, refactor, best-practices |
|
||||
| Design | ui, ux, design-system, accessibility |
|
||||
| Productivity | workflow, automation, git |
|
||||
|
||||
## Tips for Effective Searches
|
||||
|
||||
1. **Use specific keywords**: "react testing" is better than just "testing"
|
||||
2. **Try alternative terms**: If "deploy" doesn't work, try "deployment" or "ci-cd"
|
||||
3. **Check popular sources**: Many skills come from `vercel-labs/agent-skills` or `ComposioHQ/awesome-claude-skills`
|
||||
|
||||
## When No Skills Are Found
|
||||
|
||||
If no relevant skills exist:
|
||||
|
||||
1. Acknowledge that no existing skill was found
|
||||
2. Offer to help with the task directly using your general capabilities
|
||||
3. Suggest the user could create their own skill with `npx skills init`
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
I searched for skills related to "xyz" but didn't find any matches.
|
||||
I can still help you with this task directly! Would you like me to proceed?
|
||||
|
||||
If this is something you do often, you could create your own skill:
|
||||
npx skills init my-xyz-skill
|
||||
```

# End-to-End Testing with Playwright Test Runner
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
pnpm add -D @playwright/test @nuxt/test-utils
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
```ts
|
||||
// playwright.config.ts
|
||||
import { fileURLToPath } from 'node:url'
|
||||
import { defineConfig, devices } from '@playwright/test'
|
||||
import type { ConfigOptions } from '@nuxt/test-utils/playwright'
|
||||
|
||||
export default defineConfig<ConfigOptions>({
|
||||
use: {
|
||||
nuxt: {
|
||||
rootDir: fileURLToPath(new URL('.', import.meta.url)),
|
||||
},
|
||||
},
|
||||
// ...
|
||||
})
|
||||
```
|
||||
|
||||
## Writing Tests
|
||||
|
||||
Import `expect` and `test` from `@nuxt/test-utils/playwright` (not from `@playwright/test`):
|
||||
|
||||
```ts
|
||||
// tests/example.test.ts
|
||||
import { expect, test } from '@nuxt/test-utils/playwright'
|
||||
|
||||
test('test', async ({ page, goto }) => {
|
||||
await goto('/', { waitUntil: 'hydration' })
|
||||
await expect(page.getByRole('heading')).toHaveText('Welcome to Playwright!')
|
||||
})
|
||||
```
|
||||
|
||||
The `goto` helper is Nuxt-aware and supports `waitUntil: 'hydration'`.
|
||||
|
||||
## Per-File Nuxt Configuration
|
||||
|
||||
Override Nuxt config directly in a test file:
|
||||
|
||||
```ts
|
||||
import { fileURLToPath } from 'node:url'
|
||||
import { expect, test } from '@nuxt/test-utils/playwright'
|
||||
|
||||
test.use({
|
||||
nuxt: {
|
||||
rootDir: fileURLToPath(new URL('..', import.meta.url)),
|
||||
},
|
||||
})
|
||||
|
||||
test('test', async ({ page, goto }) => {
|
||||
await goto('/', { waitUntil: 'hydration' })
|
||||
await expect(page.getByRole('heading')).toHaveText('Welcome to Playwright!')
|
||||
})
|
||||
```

# End-to-End Testing with Vitest
|
||||
|
||||
## Setup
|
||||
|
||||
In each `describe` block, call `setup()` before tests to initialize the Nuxt test environment:
|
||||
|
||||
```ts
|
||||
import { describe, test } from 'vitest'
|
||||
import { $fetch, setup } from '@nuxt/test-utils/e2e'
|
||||
|
||||
describe('My test', async () => {
|
||||
await setup({
|
||||
// test context options
|
||||
})
|
||||
|
||||
test('my test', () => {
|
||||
// ...
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
`setup` performs tasks in `beforeAll`, `beforeEach`, `afterEach`, and `afterAll`.
|
||||
|
||||
## Setup Options
|
||||
|
||||
### Nuxt Config
|
||||
- `rootDir`: Path to Nuxt app directory (default: `'.'`)
|
||||
- `configFile`: Configuration file name (default: `'nuxt.config'`)
|
||||
|
||||
### Timings
|
||||
- `setupTimeout`: Time in ms for setup to complete (default: `120000`, `240000` on Windows)
|
||||
- `teardownTimeout`: Time in ms for teardown (default: `30000`)
|
||||
|
||||
### Features
|
||||
- `build`: Run a separate build step (default: `true`, `false` if browser/server disabled or host provided)
|
||||
- `server`: Launch a server for requests (default: `true`, `false` if host provided)
|
||||
- `port`: Fixed test server port (default: `undefined`, auto-assigned)
|
||||
- `host`: URL to test against instead of building a new server (useful for testing deployed apps)
|
||||
- `browser`: Launch a Playwright browser instance (default: `false`)
|
||||
- `browserOptions`:
|
||||
- `type`: `'chromium'` | `'firefox'` | `'webkit'`
|
||||
- `launch`: Playwright launch options
|
||||
- `runner`: Test runner (`'vitest'` | `'jest'` | `'cucumber'`, default: `'vitest'`)
|
||||
|
||||
## API Helpers
|
||||
|
||||
### `$fetch(url)`
|
||||
|
||||
Get the HTML of a server-rendered page:
|
||||
|
||||
```ts
|
||||
import { $fetch } from '@nuxt/test-utils/e2e'
|
||||
|
||||
const html = await $fetch('/')
|
||||
```
|
||||
|
||||
### `fetch(url)`
|
||||
|
||||
Get the full response:
|
||||
|
||||
```ts
|
||||
import { fetch } from '@nuxt/test-utils/e2e'
|
||||
|
||||
const res = await fetch('/')
|
||||
const { body, headers } = res
|
||||
```
|
||||
|
||||
### `url(path)`
|
||||
|
||||
Get the full URL including the test server port:
|
||||
|
||||
```ts
|
||||
import { url } from '@nuxt/test-utils/e2e'
|
||||
|
||||
const pageUrl = url('/page')
|
||||
// 'http://localhost:6840/page'
|
||||
```
|
||||
|
||||
### `createPage(url)`
|
||||
|
||||
Create a Playwright browser page (requires `browser: true` in setup):
|
||||
|
||||
```ts
|
||||
import { createPage } from '@nuxt/test-utils/e2e'
|
||||
|
||||
const page = await createPage('/page')
|
||||
// Full Playwright Page API available
|
||||
```
|
||||
|
||||
## Target Host Example
|
||||
|
||||
Test against a running server instead of building:
|
||||
|
||||
```ts
|
||||
import { createPage, setup } from '@nuxt/test-utils/e2e'
|
||||
import { describe, expect, it } from 'vitest'
|
||||
|
||||
describe('login page', async () => {
|
||||
await setup({
|
||||
host: 'http://localhost:8787',
|
||||
})
|
||||
|
||||
it('displays the email and password fields', async () => {
|
||||
const page = await createPage('/login')
|
||||
expect(await page.getByTestId('email').isVisible()).toBe(true)
|
||||
expect(await page.getByTestId('password').isVisible()).toBe(true)
|
||||
})
|
||||
})
|
||||
```

# Installation & Configuration
|
||||
|
||||
## Dependencies
|
||||
|
||||
```bash
|
||||
pnpm add -D @nuxt/test-utils vitest @vue/test-utils happy-dom playwright-core
|
||||
```
|
||||
|
||||
## Nuxt Config
|
||||
|
||||
Add the test utils module for Vitest integration in DevTools (optional):
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
modules: [
|
||||
'@nuxt/test-utils/module',
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
## Vitest Config (Project-Based Setup)
|
||||
|
||||
Use Vitest projects for fine-grained control over which tests run in which environment:
|
||||
|
||||
```ts
|
||||
// vitest.config.ts
|
||||
import { defineConfig } from 'vitest/config'
|
||||
import { defineVitestProject } from '@nuxt/test-utils/config'
|
||||
|
||||
export default defineConfig({
|
||||
test: {
|
||||
projects: [
|
||||
{
|
||||
test: {
|
||||
name: 'unit',
|
||||
include: ['test/unit/*.{test,spec}.ts'],
|
||||
environment: 'node',
|
||||
},
|
||||
},
|
||||
{
|
||||
test: {
|
||||
name: 'e2e',
|
||||
include: ['test/e2e/*.{test,spec}.ts'],
|
||||
environment: 'node',
|
||||
},
|
||||
},
|
||||
await defineVitestProject({
|
||||
test: {
|
||||
name: 'nuxt',
|
||||
include: ['test/nuxt/*.{test,spec}.ts'],
|
||||
environment: 'nuxt',
|
||||
},
|
||||
}),
|
||||
],
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
**Important:** Requires `"type": "module"` in `package.json`, or rename to `vitest.config.m{ts,js}`.
|
||||
|
||||
## Alternative: Simple Setup
|
||||
|
||||
If all tests should run in the Nuxt environment:
|
||||
|
||||
```ts
|
||||
// vitest.config.ts
|
||||
import { defineVitestConfig } from '@nuxt/test-utils/config'
|
||||
|
||||
export default defineVitestConfig({
|
||||
test: {
|
||||
environment: 'nuxt',
|
||||
// environmentOptions: {
|
||||
// nuxt: {
|
||||
// domEnvironment: 'happy-dom', // 'happy-dom' (default) or 'jsdom'
|
||||
// overrides: {
|
||||
// // other Nuxt config
|
||||
// }
|
||||
// }
|
||||
// }
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Opt out of the Nuxt environment per test file with a comment:
|
||||
|
||||
```ts
|
||||
// @vitest-environment node
|
||||
import { test } from 'vitest'
|
||||
|
||||
test('my test', () => {
|
||||
// runs without Nuxt environment
|
||||
})
|
||||
```
|
||||
|
||||
## Recommended Test Directory Structure
|
||||
|
||||
```
|
||||
test/
|
||||
├── e2e/ # End-to-end tests (node environment)
|
||||
│ └── ssr.test.ts
|
||||
├── nuxt/ # Tests needing Nuxt runtime (nuxt environment)
|
||||
│ ├── components.test.ts
|
||||
│ └── composables.test.ts
|
||||
└── unit/ # Pure unit tests (node environment)
|
||||
└── utils.test.ts
|
||||
```
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
npx vitest
|
||||
|
||||
# Run only unit tests
|
||||
npx vitest --project unit
|
||||
|
||||
# Run only Nuxt tests
|
||||
npx vitest --project nuxt
|
||||
|
||||
# Run tests in watch mode
|
||||
npx vitest --watch
|
||||
```
|
||||
|
||||
## Environment Variables
|
||||
|
||||
Use a `.env.test` file for test-specific environment variables.
|
||||
|
||||
## TypeScript Support
|
||||
|
||||
Test files in `test/nuxt/` and `tests/nuxt/` are automatically included in the Nuxt app TypeScript context, so they recognize `~/`, `@/`, `#imports` aliases and auto-imports.
|
||||
|
||||
To add other directories to the Nuxt TypeScript context:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
typescript: {
|
||||
tsConfig: {
|
||||
include: [
|
||||
// relative to generated .nuxt/tsconfig.json
|
||||
'../test/other-nuxt-context/**/*',
|
||||
],
|
||||
},
|
||||
},
|
||||
})
|
||||

# Test Helpers
|
||||
|
||||
All helpers are imported from `@nuxt/test-utils/runtime`.
|
||||
|
||||
## `mountSuspended`
|
||||
|
||||
Mounts any Vue component within the Nuxt environment, allowing async setup and access to plugin injections. Wraps `@vue/test-utils` `mount` under the hood.
|
||||
|
||||
```ts
|
||||
import { mountSuspended } from '@nuxt/test-utils/runtime'
|
||||
import { SomeComponent } from '#components'
|
||||
|
||||
it('can mount some component', async () => {
|
||||
const component = await mountSuspended(SomeComponent)
|
||||
expect(component.text()).toMatchInlineSnapshot('"This is an auto-imported component"')
|
||||
})
|
||||
```
|
||||
|
||||
Mount with a route:
|
||||
|
||||
```ts
|
||||
import { mountSuspended } from '@nuxt/test-utils/runtime'
|
||||
import App from '~/app.vue'
|
||||
|
||||
it('can mount an app', async () => {
|
||||
const component = await mountSuspended(App, { route: '/test' })
|
||||
expect(component.html()).toMatchInlineSnapshot(`
|
||||
"<div>This is an auto-imported component</div>
|
||||
<div> I am a global component </div>
|
||||
<div>/</div>
|
||||
<a href="/test"> Test link </a>"
|
||||
`)
|
||||
})
|
||||
```
|
||||
|
||||
**Options:** Accepts all `@vue/test-utils` mount options plus:
|
||||
- `route`: initial route string, or `false` to skip initial route change (default: `/`)
|
||||
|
||||
## `renderSuspended`
|
||||
|
||||
Renders a component using `@testing-library/vue` within the Nuxt environment. Requires `@testing-library/vue` as a dependency.
|
||||
|
||||
```ts
|
||||
import { renderSuspended } from '@nuxt/test-utils/runtime'
|
||||
import { SomeComponent } from '#components'
|
||||
import { screen } from '@testing-library/vue'
|
||||
|
||||
it('can render some component', async () => {
|
||||
await renderSuspended(SomeComponent)
|
||||
expect(screen.getByText('This is an auto-imported component')).toBeDefined()
|
||||
})
|
||||
```
|
||||
|
||||
The component is rendered inside `<div id="test-wrapper"></div>`.
|
||||
|
||||
**Options:** Accepts all `@testing-library/vue` render options plus:
|
||||
- `route`: initial route string, or `false` to skip initial route change (default: `/`)
|
||||
|
||||
## `mockNuxtImport`
|
||||
|
||||
Mocks Nuxt auto-imported functions. This is a macro that transforms to `vi.mock` (hoisted).
|
||||
|
||||
**Can only be used once per mocked import per test file.**
|
||||
|
||||
```ts
|
||||
import { mockNuxtImport } from '@nuxt/test-utils/runtime'
|
||||
|
||||
mockNuxtImport('useState', () => {
|
||||
return () => {
|
||||
return { value: 'mocked storage' }
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### With type safety and original implementation
|
||||
|
||||
```ts
|
||||
import { mockNuxtImport } from '@nuxt/test-utils/runtime'
|
||||
|
||||
mockNuxtImport<typeof useState>('useState', (original) => {
|
||||
return (...args) => {
|
||||
return { ...original('some-key'), value: 'mocked state' }
|
||||
}
|
||||
})
|
||||
|
||||
// Or pass the function directly
|
||||
mockNuxtImport(useState, (original) => {
|
||||
return (...args) => {
|
||||
return { ...original('some-key'), value: 'mocked state' }
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Different implementations per test
|
||||
|
||||
Use `vi.hoisted` to create mutable mocks:
|
||||
|
||||
```ts
|
||||
import { vi } from 'vitest'
|
||||
import { mockNuxtImport } from '@nuxt/test-utils/runtime'
|
||||
|
||||
const { useStateMock } = vi.hoisted(() => {
|
||||
return {
|
||||
useStateMock: vi.fn(() => {
|
||||
return { value: 'mocked storage' }
|
||||
}),
|
||||
}
|
||||
})
|
||||
|
||||
mockNuxtImport('useState', () => {
|
||||
return useStateMock
|
||||
})
|
||||
|
||||
// In a test:
|
||||
useStateMock.mockImplementation(() => {
|
||||
return { value: 'something else' }
|
||||
})
|
||||
```
|
||||
|
||||
### Alternative: per-test mocking with vi.fn
|
||||
|
||||
```ts
|
||||
import { beforeEach, vi } from 'vitest'
|
||||
import { mockNuxtImport } from '@nuxt/test-utils/runtime'
|
||||
|
||||
mockNuxtImport(useRoute, original => vi.fn(original))
|
||||
|
||||
beforeEach(() => {
|
||||
vi.resetAllMocks()
|
||||
})
|
||||
|
||||
// In a test:
|
||||
const useRouteOriginal = vi.mocked(useRoute).getMockImplementation()!
|
||||
vi.mocked(useRoute).mockImplementation(
|
||||
(...args) => ({ ...useRouteOriginal(...args), path: '/mocked' }),
|
||||
)
|
||||
```
|
||||
|
||||
## `mockComponent`
|
||||
|
||||
Mocks a Nuxt component by PascalCase name or relative path.
|
||||
|
||||
```ts
|
||||
import { mockComponent } from '@nuxt/test-utils/runtime'
|
||||
|
||||
// By component name
|
||||
mockComponent('MyComponent', {
|
||||
props: {
|
||||
value: String,
|
||||
},
|
||||
setup(props) {
|
||||
// ...
|
||||
},
|
||||
})
|
||||
|
||||
// By path with factory function
|
||||
mockComponent('~/components/my-component.vue', () => {
|
||||
return defineComponent({
|
||||
setup(props) {
|
||||
// ...
|
||||
},
|
||||
})
|
||||
})
|
||||
|
||||
// Redirect to a mock SFC
|
||||
mockComponent('MyComponent', () => import('./MockComponent.vue'))
|
||||
```
|
||||
|
||||
**Note:** Cannot reference local variables in the factory function (hoisted). Import dependencies inside the factory:
|
||||
|
||||
```ts
|
||||
mockComponent('MyComponent', async () => {
|
||||
const { ref, h } = await import('vue')
|
||||
|
||||
return defineComponent({
|
||||
setup(props) {
|
||||
const counter = ref(0)
|
||||
return () => h('div', null, counter.value)
|
||||
},
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## `registerEndpoint`
|
||||
|
||||
Creates a mock Nitro endpoint that returns test data.
|
||||
|
||||
```ts
|
||||
import { registerEndpoint } from '@nuxt/test-utils/runtime'
|
||||
|
||||
// Simple GET endpoint
|
||||
registerEndpoint('/test/', () => ({
|
||||
test: 'test-field',
|
||||
}))
|
||||
|
||||
// With specific HTTP method
|
||||
registerEndpoint('/test/', {
|
||||
method: 'POST',
|
||||
handler: () => ({ test: 'test-field' }),
|
||||
})
|
||||
```
|
||||
|
||||
Options object properties:
|
||||
- `handler`: event handler function
|
||||
- `method`: (optional) HTTP method to match (e.g., 'GET', 'POST')
|
||||
- `once`: (optional) if true, handler is removed after first matching request

# Built-In Mocks
|
||||
|
||||
`@nuxt/test-utils` provides built-in mocks for browser APIs in the DOM test environment.
|
||||
|
||||
## `intersectionObserver`
|
||||
|
||||
- **Default:** `true`
|
||||
- Creates a dummy class without any functionality for the IntersectionObserver API.
|
||||
|
||||
## `indexedDB`
|
||||
|
||||
- **Default:** `false`
|
||||
- Uses [`fake-indexeddb`](https://github.com/dumbmatter/fakeIndexedDB) to create a functional mock of the IndexedDB API.
|
||||
|
||||
## Configuration
|
||||
|
||||
```ts
|
||||
// vitest.config.ts
|
||||
import { defineVitestConfig } from '@nuxt/test-utils/config'
|
||||
|
||||
export default defineVitestConfig({
|
||||
test: {
|
||||
environmentOptions: {
|

nuxt: {

mock: {

intersectionObserver: true,

indexedDb: true,
|
||||
},

# Nuxt Runtime Environment
|
||||
|
||||
## Overview
|
||||
|
||||
The Nuxt test environment initializes a global Nuxt app before tests run, including plugins and `app.vue`. This gives tests access to auto-imports, composables, and injections.
|
||||
|
||||
Tests run in `happy-dom` (default) or `jsdom`. Be careful not to mutate global state, or reset it afterwards.
|
||||
|
||||
## Environment Separation
|
||||
|
||||
- **`test/unit/`** — Node environment, fast, no Nuxt runtime. For pure logic, utilities, helpers.
|
||||
- **`test/nuxt/`** — Nuxt environment, has access to auto-imports, composables, plugins. For components and composables that depend on Nuxt.
|
||||
- **`test/e2e/`** — Node environment, launches a full Nuxt server. For end-to-end testing.
|
||||
|
||||
**Important:** `@nuxt/test-utils/runtime` and `@nuxt/test-utils/e2e` cannot be used in the same file — they need different environments.
|
||||
|
||||
## Naming Convention for Mixed Setups
|
||||
|
||||
If using the simple (non-project) config, separate by file extension:
|
||||
|
||||
- `app.nuxt.spec.ts` — runs in Nuxt environment (uses `@nuxt/test-utils/runtime`)
|
||||
- `app.e2e.spec.ts` — runs in Node environment (uses `@nuxt/test-utils/e2e`)
|
||||
|
||||
Or use per-file environment comments:
|
||||
|
||||
```ts
|
||||
// @vitest-environment nuxt
|
||||
```
|
||||
|
||||
## Environment Options
|
||||
|
||||
Configure in `vitest.config.ts`:
|
||||
|
||||
```ts
|
||||
import { defineVitestConfig } from '@nuxt/test-utils/config'
|
||||
|
||||
export default defineVitestConfig({
|
||||
test: {
|
||||
environmentOptions: {
|
||||
nuxt: {
|
||||
domEnvironment: 'happy-dom', // or 'jsdom'
|
||||
overrides: {
|
||||
// Nuxt config overrides for testing
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
})
|
||||
```

# Nuxt UI
|
||||
|
||||
Vue component library built on [Reka UI](https://reka-ui.com/) + [Tailwind CSS](https://tailwindcss.com/) + [Tailwind Variants](https://www.tailwind-variants.org/). Works with Nuxt, Vue (Vite), Laravel (Inertia), and AdonisJS (Inertia).
|
||||
|
||||
## Installation
|
||||
|
||||
### Nuxt
|
||||
|
||||
```bash
|
||||
pnpm add @nuxt/ui tailwindcss
|
||||
```
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
modules: ['@nuxt/ui'],
|
||||
css: ['~/assets/css/main.css']
|
||||
})
|
||||
```
|
||||
|
||||
```css
|
||||
/* app/assets/css/main.css */
|
||||
@import "tailwindcss";
|
||||
@import "@nuxt/ui";
|
||||
```
|
||||
|
||||
```vue
|
||||
<!-- app.vue -->
|
||||
<template>
|
||||
<UApp>
|
||||
<NuxtPage />
|
||||
</UApp>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Vue (Vite)
|
||||
|
||||
```bash
|
||||
pnpm add @nuxt/ui tailwindcss
|
||||
```
|
||||
|
||||
```ts
|
||||
// vite.config.ts
|
||||
import { defineConfig } from 'vite'
|
||||
import vue from '@vitejs/plugin-vue'
|
||||
import ui from '@nuxt/ui/vite'
|
||||
|
||||
export default defineConfig({
|
||||
plugins: [
|
||||
vue(),
|
||||
ui()
|
||||
]
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// src/main.ts
|
||||
import './assets/main.css'
|
||||
import { createApp } from 'vue'
|
||||
import { createRouter, createWebHistory } from 'vue-router'
|
||||
import ui from '@nuxt/ui/vue-plugin'
|
||||
import App from './App.vue'
|
||||
|
||||
const app = createApp(App)
|
||||
|
||||
const router = createRouter({
|
||||
routes: [],
|
||||
history: createWebHistory()
|
||||
})
|
||||
|
||||
app.use(router)
|
||||
app.use(ui)
|
||||
app.mount('#app')
|
||||
```
|
||||
|
||||
```css
|
||||
/* assets/main.css */
|
||||
@import "tailwindcss";
|
||||
@import "@nuxt/ui";
|
||||
```
|
||||
|
||||
```vue
|
||||
<!-- src/App.vue -->
|
||||
<template>
|
||||
<UApp>
|
||||
<RouterView />
|
||||
</UApp>
|
||||
</template>
|
||||
```
|
||||
|
||||
> **Vue**: Add `class="isolate"` to your root `<div id="app">` in `index.html`.
|
||||
|
||||
> **Vue + Inertia**: Use `ui({ router: 'inertia' })` in `vite.config.ts`.
|
||||
|
||||
### UApp
|
||||
|
||||
Wrapping your app in `UApp` is **required** — it provides global config for toasts, tooltips, and programmatic overlays. It also accepts a `locale` prop for i18n (see [composables reference](references/composables.md)).
|
||||
|
||||
## Icons
|
||||
|
||||
Nuxt UI uses [Iconify](https://iconify.design/) for 200,000+ icons. In Nuxt, `@nuxt/icon` is auto-registered. In Vue, icons work out of the box via the Vite plugin.
|
||||
|
||||
### Naming convention
|
||||
|
||||
Icons use the format `i-{collection}-{name}`:
|
||||
|
||||
```vue
|
||||
<UIcon name="i-lucide-sun" class="size-5" />
|
||||
<UButton icon="i-lucide-plus" label="Add" />
|
||||
<UAlert icon="i-lucide-info" title="Heads up" />
|
||||
```
|
||||
|
||||
> Browse all icons at [icones.js.org](https://icones.js.org). The `lucide` collection is used throughout Nuxt UI defaults.
|
||||
|
||||
### Install icon collections locally
|
||||
|
||||
```bash
|
||||
pnpm i @iconify-json/lucide
|
||||
pnpm i @iconify-json/simple-icons
|
||||
```
|
||||
|
||||
### Custom local collections (Nuxt)
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
icon: {
|
||||
customCollections: [{
|
||||
prefix: 'custom',
|
||||
dir: './app/assets/icons'
|
||||
}]
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
```vue
|
||||
<UIcon name="i-custom-my-icon" />
|
||||
```
|
||||
|
||||
## Theming & Branding
|
||||
|
||||
Nuxt UI ships with a default look. The goal is to adapt it to your brand so every app looks unique.
|
||||
|
||||
**Always use semantic utilities** (`text-default`, `bg-elevated`, `border-muted`), never raw Tailwind palette colors. See [references/theming.md](references/theming.md) for the full list.
|
||||
|
||||
### Colors
|
||||
|
||||
7 semantic colors (`primary`, `secondary`, `success`, `info`, `warning`, `error`, `neutral`) configurable at runtime:
|
||||
|
||||
```ts
|
||||
// Nuxt — app.config.ts
|
||||
export default defineAppConfig({
|
||||
ui: { colors: { primary: 'indigo', neutral: 'zinc' } }
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// Vue — vite.config.ts
|
||||
import { defineConfig } from 'vite'
|
||||
import vue from '@vitejs/plugin-vue'
|
||||
import ui from '@nuxt/ui/vite'
|
||||
|
||||
export default defineConfig({
|
||||
plugins: [
|
||||
vue(),
|
||||
ui({
|
||||
ui: { colors: { primary: 'indigo', neutral: 'zinc' } }
|
||||
})
|
||||
]
|
||||
})
|
||||
```
|
||||
|
||||
### Customizing components
|
||||
|
||||
**Override priority** (highest wins): `ui` prop / `class` prop > global config > theme defaults.
|
||||
|
||||
The `ui` prop overrides a component's **slots** after variants are computed — it wins over everything:
|
||||
|
||||
```vue
|
||||
<UButton :ui="{ base: 'rounded-none', trailingIcon: 'size-3 rotate-90' }" />
|
||||
<UCard :ui="{ header: 'bg-muted', body: 'p-8' }" />
|
||||
```
|
||||
|
||||
**Read the generated theme file** to find slot names for any component:
|
||||
|
||||
- **Nuxt**: `.nuxt/ui/<component>.ts`
|
||||
- **Vue**: `node_modules/.nuxt-ui/ui/<component>.ts`
|
||||
|
||||
> For CSS variables, custom colors, global config, compound variants, and a **full brand customization playbook**, see [references/theming.md](references/theming.md)
|
||||
|
||||
## Composables
|
||||
|
||||
```ts
|
||||
// Notifications
|
||||
const toast = useToast()
|
||||
toast.add({ title: 'Saved', color: 'success', icon: 'i-lucide-check' })
|
||||
|
||||
// Programmatic overlays
|
||||
const overlay = useOverlay()
|
||||
const modal = overlay.create(MyModal)
|
||||
const { result } = modal.open({ title: 'Confirm' })
|
||||
await result
|
||||
|
||||
// Keyboard shortcuts
|
||||
defineShortcuts({
|
||||
meta_k: () => openSearch(),
|
||||
escape: () => close()
|
||||
})
|
||||
```
|
||||
|
||||
> For full composable reference, see [references/composables.md](references/composables.md)
|
||||
|
||||
## Form validation
|
||||
|
||||
Uses Standard Schema — works with Zod, Valibot, Yup, or Joi.
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import { z } from 'zod'
|
||||
|
||||
const schema = z.object({
|
||||
email: z.string().email('Invalid email'),
|
||||
password: z.string().min(8, 'Min 8 characters')
|
||||
})
|
||||
|
||||
type Schema = z.output<typeof schema>
|
||||
const state = reactive<Partial<Schema>>({ email: '', password: '' })
|
||||
|
||||
function onSubmit() {
|
||||
// UForm validates before emitting @submit — state is valid here
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<UForm :schema="schema" :state="state" @submit="onSubmit">
|
||||
<UFormField name="email" label="Email" required>
|
||||
<UInput v-model="state.email" type="email" />
|
||||
</UFormField>
|
||||
|
||||
<UFormField name="password" label="Password" required>
|
||||
<UInput v-model="state.password" type="password" />
|
||||
</UFormField>
|
||||
|
||||
<UButton type="submit">Sign in</UButton>
|
||||
</UForm>
|
||||
</template>
|
||||
```
|
||||
|
||||
> For all form components and validation patterns, see [references/components.md](references/components.md#form)
|
||||
|
||||
## Overlays
|
||||
|
||||
```vue
|
||||
<!-- Modal -->
|
||||
<UModal v-model:open="isOpen" title="Edit" description="Edit your profile">
|
||||
<template #body>Content</template>
|
||||
<template #footer>
|
||||
<UButton variant="ghost" @click="isOpen = false">Cancel</UButton>
|
||||
<UButton @click="save">Save</UButton>
|
||||
</template>
|
||||
</UModal>
|
||||
|
||||
<!-- Slideover (side panel) -->
|
||||
<USlideover v-model:open="isOpen" title="Settings" side="right">
|
||||
<template #body>Content</template>
|
||||
</USlideover>
|
||||
|
||||
<!-- Dropdown menu (flat array) -->
|
||||
<UDropdownMenu :items="[
|
||||
{ label: 'Edit', icon: 'i-lucide-pencil' },
|
||||
{ type: 'separator' },
|
||||
{ label: 'Delete', icon: 'i-lucide-trash', color: 'error' }
|
||||
]">
|
||||
<UButton icon="i-lucide-ellipsis-vertical" variant="ghost" />
|
||||
</UDropdownMenu>
|
||||
|
||||
<!-- Dropdown menu (nested array — groups with automatic separators) -->
|
||||
<UDropdownMenu :items="[
|
||||
[{ label: 'Edit', icon: 'i-lucide-pencil' }, { label: 'Duplicate', icon: 'i-lucide-copy' }],
|
||||
[{ label: 'Delete', icon: 'i-lucide-trash', color: 'error' }]
|
||||
]">
|
||||
<UButton icon="i-lucide-ellipsis-vertical" variant="ghost" />
|
||||
</UDropdownMenu>
|
||||
```

|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import { z } from 'zod'
|
||||
|
||||
const schema = z.object({
|
||||
email: z.string().email('Invalid email'),
|
||||
password: z.string().min(8, 'Min 8 characters')
|
||||
})
|
||||
|
||||
type Schema = z.output<typeof schema>
|
||||
const state = reactive<Partial<Schema>>({ email: '', password: '' })
|
||||
const form = ref()
|
||||
|
||||
async function onSubmit() {
|
||||
await form.value.validate()
|
||||
}
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<UForm ref="form" :schema="schema" :state="state" @submit="onSubmit">
|
||||
<UFormField name="email" label="Email" required>
|
||||
<UInput v-model="state.email" type="email" />
|
||||
</UFormField>
|
||||
|
||||
<UFormField name="password" label="Password" required>
|
||||
<UInput v-model="state.password" type="password" />
|
||||
</UFormField>
|
||||
|
||||
<UButton type="submit">Submit</UButton>
|
||||
</UForm>
|
||||
</template>
|
||||
```
|
||||
|
||||
With Valibot:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import * as v from 'valibot'
|
||||
|
||||
const schema = v.object({
|
||||
email: v.pipe(v.string(), v.email('Invalid email')),
|
||||
password: v.pipe(v.string(), v.minLength(8, 'Min 8 characters'))
|
||||
})
|
||||
</script>
|
||||
```

||||
|
||||

# Theming
|
||||
|
||||
## Semantic colors
|
||||
|
||||
| Color | Default | Purpose |
|
||||
|---|---|---|
|
||||
| `primary` | green | CTAs, active states, brand |
|
||||
| `secondary` | blue | Secondary actions |
|
||||
| `success` | green | Success messages |
|
||||
| `info` | blue | Informational |
|
||||
| `warning` | yellow | Warnings |
|
||||
| `error` | red | Errors, destructive actions |
|
||||
| `neutral` | slate | Text, borders, disabled |
|
||||
|
||||
## Configuring colors
|
||||
|
||||
```ts
|
||||
// Nuxt — app.config.ts
|
||||
export default defineAppConfig({
|
||||
ui: {
|
||||
colors: {
|
||||
primary: 'indigo',
|
||||
secondary: 'violet',
|
||||
success: 'emerald',
|
||||
error: 'rose',
|
||||
neutral: 'zinc'
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// Vue — vite.config.ts
|
||||
ui({
|
||||
ui: {
|
||||
colors: { primary: 'indigo', secondary: 'violet', neutral: 'zinc' }
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
You can only use colors that exist in your theme — either [Tailwind's default colors](https://tailwindcss.com/docs/colors) or custom colors defined with `@theme`.
|
||||
|
||||
## Adding custom colors
|
||||
|
||||
1. Define all 11 shades in CSS:
|
||||
|
||||
```css
|
||||
/* assets/css/main.css */
|
||||
@theme static {
|
||||
--color-brand-50: #fef2f2;
|
||||
--color-brand-100: #fee2e2;
|
||||
--color-brand-200: #fecaca;
|
||||
--color-brand-300: #fca5a5;
|
||||
--color-brand-400: #f87171;
|
||||
--color-brand-500: #ef4444;
|
||||
--color-brand-600: #dc2626;
|
||||
--color-brand-700: #b91c1c;
|
||||
--color-brand-800: #991b1b;
|
||||
--color-brand-900: #7f1d1d;
|
||||
--color-brand-950: #450a0a;
|
||||
}
|
||||
```
|
||||
|
||||
2. Assign it as a semantic color value: `ui: { colors: { primary: 'brand' } }`
|
||||
|
||||
You can only use colors that have all shades defined — either from Tailwind's defaults or custom `@theme` definitions.
|
||||
|
||||
### Extending with new semantic color names
|
||||
|
||||
If you need a new semantic color beyond the defaults (e.g., `tertiary`), register it in `theme.colors`:
|
||||
|
||||
```ts
|
||||
// Nuxt — nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
ui: {
|
||||
theme: {
|
||||
colors: ['primary', 'secondary', 'tertiary', 'info', 'success', 'warning', 'error']
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// Vue — vite.config.ts
|
||||
ui({
|
||||
theme: {
|
||||
colors: ['primary', 'secondary', 'tertiary', 'info', 'success', 'warning', 'error']
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
Then assign it: `ui: { colors: { tertiary: 'indigo' } }` and use it via the `color` prop: `<UButton color="tertiary">`.
|
||||
|
||||
## CSS utilities
|
||||
|
||||
### Text
|
||||
|
||||
| Class | Use | Light value | Dark value |
|
||||
|---|---|---|---|
|
||||
| `text-default` | Body text | `neutral-700` | `neutral-200` |
|
||||
| `text-muted` | Secondary text | `neutral-500` | `neutral-400` |
|
||||
| `text-dimmed` | Placeholders, hints | `neutral-400` | `neutral-500` |
|
||||
| `text-toned` | Subtitles | `neutral-600` | `neutral-300` |
|
||||
| `text-highlighted` | Headings, emphasis | `neutral-900` | `white` |
|
||||
| `text-inverted` | On dark/light backgrounds | `white` | `neutral-900` |
|
||||
|
||||
### Background
|
||||
|
||||
| Class | Use | Light value | Dark value |
|
||||
|---|---|---|---|
|
||||
| `bg-default` | Page background | `white` | `neutral-900` |
|
||||
| `bg-muted` | Subtle sections | `neutral-50` | `neutral-800` |
|
||||
| `bg-elevated` | Cards, modals | `neutral-100` | `neutral-800` |
|
||||
| `bg-accented` | Hover states | `neutral-200` | `neutral-700` |
|
||||
| `bg-inverted` | Inverted sections | `neutral-900` | `white` |
|
||||
|
||||
### Border
|
||||
|
||||
| Class | Use | Light value | Dark value |
|
||||
|---|---|---|---|
|
||||
| `border-default` | Default borders | `neutral-200` | `neutral-800` |
|
||||
| `border-muted` | Subtle borders | `neutral-200` | `neutral-700` |
|
||||
| `border-accented` | Emphasized borders | `neutral-300` | `neutral-700` |
|
||||
| `border-inverted` | Inverted borders | `neutral-900` | `white` |
|
||||
|
||||
### Semantic color utilities
|
||||
|
||||
Each semantic color (`primary`, `secondary`, `success`, `info`, `warning`, `error`) is available as a Tailwind utility: `text-primary`, `bg-primary`, `border-primary`, `ring-primary`, etc.
|
||||
|
||||
They resolve to shade **500** in light mode and shade **400** in dark mode (via `--ui-<color>` CSS variables). This is generated at runtime by the colors plugin — you don't need to write dark-mode variants manually.
|
||||
|
||||
To adjust which shade is used, override `--ui-primary` (or any semantic color) in your `main.css`:
|
||||
|
||||
```css
|
||||
:root { --ui-primary: var(--ui-color-primary-600); }
|
||||
.dark { --ui-primary: var(--ui-color-primary-300); }
|
||||
```
|
||||
|
||||
### CSS variables
|
||||
|
||||
All customizable in `main.css`:
|
||||
|
||||
```css
|
||||
:root {
|
||||
--ui-radius: 0.25rem; /* base radius for all components */
|
||||
--ui-container: 80rem; /* UContainer max-width */
|
||||
--ui-header-height: 4rem; /* UHeader height */
|
||||
--ui-primary: var(--ui-color-primary-500); /* adjust shade used */
|
||||
}
|
||||
|
||||
.dark {
|
||||
--ui-primary: var(--ui-color-primary-400);
|
||||
}
|
||||
```
|
||||
|
||||
### Solid colors (black/white)
|
||||
|
||||
```css
|
||||
:root { --ui-primary: black; }
|
||||
.dark { --ui-primary: white; }
|
||||
```
|
||||
|
||||
## Component theme customization
|
||||
|
||||
### How it works
|
||||
|
||||
Components are styled with [Tailwind Variants](https://www.tailwind-variants.org/). The theme defines:
|
||||
|
||||
- **`slots`** — named style targets (e.g., `root`, `base`, `label`, `leadingIcon`)
|
||||
- **`variants`** — styles applied based on props (e.g., `color`, `variant`, `size`)
|
||||
- **`compoundVariants`** — styles for specific prop combinations (e.g., `color: 'primary'` + `variant: 'outline'`)
|
||||
- **`defaultVariants`** — default prop values when none are specified
|
||||
|
||||
### Override priority
|
||||
|
||||
**`ui` prop / `class` prop > global config > theme defaults**
|
||||
|
||||
The `ui` prop overrides slots **after** variants are computed. If the `size: 'md'` variant applies `size-5` to `trailingIcon`, and you set `:ui="{ trailingIcon: 'size-3' }"`, the `size-3` wins.
|
||||
|
||||
Tailwind Variants uses [tailwind-merge](https://github.com/dcastil/tailwind-merge) under the hood so conflicting classes are resolved automatically.
|
||||
|
||||
### Understanding the generated theme
|
||||
|
||||
Every component's full resolved theme is generated at build time. Always read this file before customizing a component — it shows exactly what classes are applied where.
|
||||
|
||||
- **Nuxt**: `.nuxt/ui/<component>.ts`
|
||||
- **Vue**: `node_modules/.nuxt-ui/ui/<component>.ts`
|
||||
|
||||
For example, the card theme:
|
||||
|
||||
```ts
|
||||
{
|
||||
slots: {
|
||||
root: "rounded-lg overflow-hidden",
|
||||
header: "p-4 sm:px-6",
|
||||
body: "p-4 sm:p-6",
|
||||
footer: "p-4 sm:px-6"
|
||||
},
|
||||
variants: {
|
||||
variant: {
|
||||
outline: { root: "bg-default ring ring-default divide-y divide-default" },
|
||||
soft: { root: "bg-elevated/50 divide-y divide-default" }
|
||||
}
|
||||
},
|
||||
defaultVariants: { variant: "outline" }
|
||||
}
|
||||
```
|
||||
|
||||
### Global config
|
||||
|
||||
Override the theme for all instances of a component:
|
||||
|
||||
```ts
|
||||
// Nuxt — app.config.ts
|
||||
export default defineAppConfig({
|
||||
ui: {
|
||||
button: {
|
||||
slots: {
|
||||
base: 'font-bold rounded-full'
|
||||
},
|
||||
variants: {
|
||||
size: {
|
||||
md: { leadingIcon: 'size-4' }
|
||||
}
|
||||
},
|
||||
compoundVariants: [{
|
||||
color: 'neutral',
|
||||
variant: 'outline',
|
||||
class: { base: 'ring-2' }
|
||||
}],
|
||||
defaultVariants: {
|
||||
color: 'neutral',
|
||||
variant: 'outline'
|
||||
}
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// Vue — vite.config.ts
|
||||
ui({
|
||||
ui: {
|
||||
button: {
|
||||
slots: { base: 'font-bold rounded-full' },
|
||||
defaultVariants: { color: 'neutral', variant: 'outline' }
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Per-instance (`ui` prop)
|
||||
|
||||
Overrides slots after variant computation:
|
||||
|
||||
```vue
|
||||
<UButton :ui="{ base: 'font-mono', trailingIcon: 'size-3 rotate-90' }" />
|
||||
<UCard :ui="{ root: 'shadow-xl', body: 'p-8' }" />
|
||||
```
|
||||
|
||||
### Per-instance (`class` prop)
|
||||
|
||||
Overrides the `root` or `base` slot:
|
||||
|
||||
```vue
|
||||
<UButton class="rounded-none">Square</UButton>
|
||||
```
|
||||
|
||||
Components without slots (e.g., `UContainer`, `USkeleton`, `UMain`) only have the `class` prop.
|
||||
|
||||
### Theme structure patterns
|
||||
|
||||
**Slots-based** (most components — `slots` is an object in the generated theme):
|
||||
|
||||
```ts
|
||||
// global config
|
||||
ui: {
|
||||
button: {
|
||||
slots: { base: 'font-bold' }
|
||||
}
|
||||
}
|
||||
// per instance
|
||||
<UButton :ui="{ base: 'font-bold' }" />
|
||||
```
|
||||
|
||||
**Flat base** (`base` is a top-level string in the generated theme):
|
||||
|
||||
```ts
|
||||
// global config
|
||||
ui: {
|
||||
container: {
|
||||
base: 'max-w-lg'
|
||||
}
|
||||
}
|
||||
// per instance — class prop only
|
||||
<UContainer class="max-w-lg" />
|
||||
```
|
||||
|
||||
Always check the generated theme file to see which pattern applies.
|
||||
|
||||
## Dark mode
|
||||
|
||||
```ts
|
||||
const colorMode = useColorMode()
|
||||
colorMode.preference = 'dark' // 'light', 'dark', 'system'
|
||||
```
|
||||
|
||||
```vue
|
||||
<UColorModeButton /> <!-- Toggle -->
|
||||
<UColorModeSelect /> <!-- Dropdown -->
|
||||
```
|
||||
|
||||
## Fonts
|
||||
|
||||
```css
|
||||
/* assets/css/main.css */
|
||||
@theme {
|
||||
--font-sans: 'Public Sans', system-ui, sans-serif;
|
||||
--font-mono: 'JetBrains Mono', monospace;
|
||||
}
|
||||
```
|
||||
|
||||
In Nuxt, fonts defined with `@theme` are automatically loaded by the `@nuxt/fonts` module.
|
||||
|
||||
## Brand customization playbook
|
||||
|
||||
Follow these steps to fully rebrand Nuxt UI (e.g., "make a Ghibli theme", "match our corporate brand"):
|
||||
|
||||
### Step 1 — Define the color palette
|
||||
|
||||
Pick colors that match the brand. Map them to semantic roles:
|
||||
|
||||
```ts
|
||||
// app.config.ts (Nuxt) or vite.config.ts (Vue)
|
||||
ui: {
|
||||
colors: {
|
||||
primary: 'emerald', // brand accent
|
||||
secondary: 'amber', // secondary accent
|
||||
success: 'green',
|
||||
info: 'sky',
|
||||
warning: 'orange',
|
||||
error: 'rose',
|
||||
neutral: 'stone' // affects all text, borders, backgrounds
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
If no Tailwind default color fits, define custom shades in CSS (see [Adding custom colors](#adding-custom-colors)):
|
||||
|
||||
```css
|
||||
@theme static {
|
||||
--color-forest-50: #f0fdf4;
|
||||
/* ... all 11 shades (50–950) ... */
|
||||
--color-forest-950: #052e16;
|
||||
}
|
||||
```
|
||||
|
||||
Then use it: `primary: 'forest'`.
|
||||
|
||||
### Step 2 — Set fonts
|
||||
|
||||
```css
|
||||
/* assets/css/main.css */
|
||||
@theme {
|
||||
--font-sans: 'Quicksand', system-ui, sans-serif;
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3 — Adjust CSS variables
|
||||
|
||||
```css
|
||||
:root {
|
||||
--ui-radius: 0.75rem; /* rounder = softer/playful, smaller = sharper/corporate */
|
||||
--ui-primary: var(--ui-color-primary-600); /* adjust which shade is used */
|
||||
}
|
||||
|
||||
.dark {
|
||||
--ui-primary: var(--ui-color-primary-400);
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4 — Override key components globally
|
||||
|
||||
Read the generated theme files to find slot names, then apply global overrides:
|
||||
|
||||
```ts
|
||||
// app.config.ts (Nuxt) or vite.config.ts (Vue)
|
||||
ui: {
|
||||
// ... colors from Step 1
|
||||
button: {
|
||||
slots: {
|
||||
base: 'rounded-full font-semibold'
|
||||
},
|
||||
defaultVariants: {
|
||||
variant: 'soft'
|
||||
}
|
||||
},
|
||||
card: {
|
||||
slots: {
|
||||
root: 'rounded-2xl shadow-lg'
|
||||
}
|
||||
},
|
||||
badge: {
|
||||
slots: {
|
||||
base: 'rounded-full'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
> **Tip**: Read `.nuxt/ui/button.ts` (Nuxt) or `node_modules/.nuxt-ui/ui/button.ts` (Vue) to see all available slots and variants before overriding.
|
||||
|
||||
### Step 5 — Verify dark mode
|
||||
|
||||
Check that both modes look correct. Adjust `--ui-primary` shade per mode and test contrast. Use `useColorMode()` to toggle during development.
|
||||
|
||||
### Quick checklist
|
||||
|
||||
| Step | What to change | Where |
|
||||
|---|---|---|
|
||||
| Colors | `primary`, `secondary`, `neutral` | `app.config.ts` / `vite.config.ts` |
|
||||
| Custom palette | 11 shades per color | `main.css` (`@theme static`) |
|
||||
| Fonts | `--font-sans`, `--font-mono` | `main.css` (`@theme`) |
|
||||
| Radius | `--ui-radius` | `main.css` (`:root`) |
|
||||
| Primary shade | `--ui-primary` | `main.css` (`:root` + `.dark`) |
|
||||
| Component shapes | Global slot overrides | `app.config.ts` / `vite.config.ts` |
|
||||
| Dark mode | Verify contrast, adjust variables | `main.css` (`.dark`) |

# Lifecycle Hooks
|
||||
|
||||
Nuxt provides hooks to tap into the build process, application lifecycle, and server runtime.
|
||||
|
||||
## Build-time Hooks (Nuxt)
|
||||
|
||||
Used in `nuxt.config.ts` or modules:
|
||||
|
||||
### In nuxt.config.ts
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
hooks: {
|
||||
'build:before': () => {
|
||||
console.log('Build starting...')
|
||||
},
|
||||
'pages:extend': (pages) => {
|
||||
// Add custom pages
|
||||
pages.push({
|
||||
name: 'custom',
|
||||
path: '/custom',
|
||||
file: '~/pages/custom.vue',
|
||||
})
|
||||
},
|
||||
'components:dirs': (dirs) => {
|
||||
// Add component directories
|
||||
dirs.push({ path: '~/extra-components' })
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### In Modules
|
||||
|
||||
```ts
|
||||
// modules/my-module.ts
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
nuxt.hook('ready', async (nuxt) => {
|
||||
console.log('Nuxt is ready')
|
||||
})
|
||||
|
||||
nuxt.hook('close', async (nuxt) => {
|
||||
console.log('Nuxt is closing')
|
||||
})
|
||||
|
||||
nuxt.hook('modules:done', () => {
|
||||
console.log('All modules loaded')
|
||||
})
|
||||
},
|
||||
})
|
||||
```

|
||||
|
||||
### In Plugins
|
||||
|
||||
```ts
|
||||
// plugins/lifecycle.ts
|
||||
export default defineNuxtPlugin((nuxtApp) => {
|
||||
nuxtApp.hook('app:created', (vueApp) => {
|
||||
console.log('Vue app created')
|
||||
})
|
||||

nitroApp.hooks.hook('render:response', (response, { event }) => {
|
||||
console.log('Sending response:', response.statusCode)
|
||||
})
|
||||
|
||||
// Before request
|
||||
nitroApp.hooks.hook('request', (event) => {
|
||||
console.log('Request:', event.path)
|
||||
})
|
||||
|
||||
// After response
|
||||
nitroApp.hooks.hook('afterResponse', (event) => {

## Custom Hooks
|
||||
|
||||
### Define Custom Hook Types
|
||||
|
||||
```ts
|
||||
// types/hooks.d.ts
|
||||
import type { HookResult } from '@nuxt/schema'
|
||||
|
||||
declare module '#app' {
|
||||
interface RuntimeNuxtHooks {
|
||||
'my-app:event': (data: MyEventData) => HookResult
|
||||
}
|
||||
}
|
||||
|
||||
declare module '@nuxt/schema' {
|
||||
interface NuxtHooks {
|
||||
'my-module:init': () => HookResult
|
||||
}
|
||||
}
|
||||
|
||||
declare module 'nitropack/types' {
|
||||
interface NitroRuntimeHooks {
|
||||
'my-server:event': (data: any) => void
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Call Custom Hooks
|
||||
|
||||
```ts
|
||||
// In a plugin
|
||||
export default defineNuxtPlugin((nuxtApp) => {
|
||||
// Call custom hook
|
||||
nuxtApp.callHook('my-app:event', { type: 'custom' })
|
||||
})
|
||||
|
||||
// In a module
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
nuxt.callHook('my-module:init')
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## useRuntimeHook
|
||||
|
||||
Call hooks at runtime from components:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Register a callback for a runtime hook
|
||||
useRuntimeHook('app:error', (error) => {
|
||||
console.error('App error:', error)
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Hook Examples
|
||||
|
||||
### Page View Tracking
|
||||
|
||||
```ts
|
||||
// plugins/analytics.client.ts
|
||||
export default defineNuxtPlugin((nuxtApp) => {
|
||||
nuxtApp.hook('page:finish', () => {
|
||||
const route = useRoute()
|
||||
analytics.track('pageview', {
|
||||
path: route.path,
|
||||
title: document.title,
|
||||
})
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
### Performance Monitoring
|
||||
|
||||
```ts
|
||||
// plugins/performance.client.ts
|
||||
export default defineNuxtPlugin((nuxtApp) => {
|
||||
let navigationStart: number
|
||||
|
||||
nuxtApp.hook('page:start', () => {
|
||||
navigationStart = performance.now()
|
||||
})
|
||||
|
||||
nuxtApp.hook('page:finish', () => {
|
||||
const duration = performance.now() - navigationStart
|
||||
console.log(`Navigation took ${duration}ms`)
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
### Inject HTML
|
||||
|
||||
```ts
|
||||
// server/plugins/inject.ts
|
||||
export default defineNitroPlugin((nitroApp) => {
|

description: Extending Nuxt applications with layers for code sharing and reusability
|

|
||||
|
||||
# Nuxt Layers
|
||||
|
||||
Layers allow sharing and reusing partial Nuxt applications across projects. They can include components, composables, pages, layouts, and configuration.
|
||||
|
||||
## Using Layers
|
||||
|
||||
### From npm Package
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
extends: [
|
||||
'@my-org/base-layer',
|
||||
'@nuxtjs/ui-layer',
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
### From Git Repository
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
extends: [
|
||||
'github:username/repo',
|
||||
'github:username/repo/base', // Subdirectory
|
||||
'github:username/repo#v1.0', // Specific tag
|
||||
'github:username/repo#dev', // Branch
|
||||
'gitlab:username/repo',
|
||||
'bitbucket:username/repo',
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
### From Local Directory
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
extends: [
|
||||
'../base-layer',
|
||||
'./layers/shared',
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
### Auto-scanned Layers
|
||||
|
||||
Place in `layers/` directory for automatic discovery:
|
||||
|
||||
```
|
||||
my-app/
|
||||
├── layers/
|
||||
│ ├── base/
|
||||
│ │ └── nuxt.config.ts
|
||||
│ └── ui/
|
||||
│ └── nuxt.config.ts
|
||||
└── nuxt.config.ts
|
||||
```
|
||||
|
||||
## Creating a Layer
|
||||
|
||||
Minimal layer structure:
|
||||
|
||||
```
|
||||
my-layer/
|
||||
├── nuxt.config.ts # Required
|
||||
├── app/
|
||||
│ ├── components/ # Auto-merged
|
||||
│ ├── composables/ # Auto-merged
|
||||
│ ├── layouts/ # Auto-merged
|
||||
│ ├── middleware/ # Auto-merged
|
||||
│ ├── pages/ # Auto-merged
|
||||
│ ├── plugins/ # Auto-merged
|
||||
│ └── app.config.ts # Merged
|
||||
├── server/ # Auto-merged
|
||||
└── package.json
|
||||
```
|
||||
|
||||
### Layer nuxt.config.ts
|
||||
|
||||
```ts
|
||||
// my-layer/nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
// Layer configuration
|
||||
app: {
|
||||
head: {
|
||||
title: 'My Layer App',
|
||||
},
|
||||
},
|
||||
// Shared modules
|
||||
modules: ['@nuxt/ui'],
|
||||
})
|
||||
```
|
||||
|
||||
### Layer Components
|
||||
|
||||
```vue
|
||||
<!-- my-layer/app/components/BaseButton.vue -->
|
||||
<template>
|
||||
<button class="base-btn">
|
||||
<slot />
|
||||
</button>
|
||||
</template>
|
||||
```
|
||||
|
||||
Use in consuming project:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<BaseButton>Click me</BaseButton>
|
||||
</template>
|
||||
```
|
||||
|
||||
### Layer Composables
|
||||
|
||||
```ts
|
||||
// my-layer/app/composables/useTheme.ts
|
||||
export function useTheme() {
|
||||
const isDark = useState('theme-dark', () => false)
|
||||
const toggle = () => isDark.value = !isDark.value
|
||||
return { isDark, toggle }
|
||||
}
|
||||
```
|
||||
|
||||
## Layer Priority
|
||||
|
||||
Override order (highest to lowest):
|
||||
1. Your project files
|
||||
2. Auto-scanned layers (alphabetically, Z > A)
|
||||
3. `extends` array (first > last)
|
||||
|
||||
Control order with prefixes:
|
||||
|
||||
```
|
||||
layers/
|
||||
├── 1.base/ # Lower priority
|
||||
└── 2.theme/ # Higher priority
|
||||
```
|
||||
|
||||
## Layer Aliases
|
||||
|
||||
Access layer files:
|
||||
|
||||
```ts
|
||||
// Auto-scanned layers get aliases
|
||||
import Component from '#layers/base/components/Component.vue'
|
||||
```
|
||||
|
||||
Named aliases:
|
||||
|
||||
```ts
|
||||
// my-layer/nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
$meta: {
|
||||
name: 'my-layer',
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// In consuming project
|
||||
import { something } from '#layers/my-layer/utils'
|
||||
```
|
||||
|
||||
## Publishing Layers
|
||||
|
||||
### As npm Package
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "my-nuxt-layer",
|
||||
"version": "1.0.0",
|
||||
"type": "module",
|
||||
"main": "./nuxt.config.ts",
|
||||
"dependencies": {
|
||||
"@nuxt/ui": "^2.0.0"
|
||||
},
|
||||
"devDependencies": {
|
||||
"nuxt": "^3.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Private Layers
|
||||
|
||||
For private git repos:
|
||||
|
||||
```bash
|
||||
export GIGET_AUTH=<github-token>
|
||||
```
|
||||
|
||||
## Layer Best Practices
|
||||
|
||||
### Use Resolved Paths
|
||||
|
||||
```ts
|
||||
// my-layer/nuxt.config.ts
|
||||
import { fileURLToPath } from 'node:url'
|
||||
import { dirname, join } from 'node:path'
|
||||
|
||||
const currentDir = dirname(fileURLToPath(import.meta.url))
|
||||
|
||||
export default defineNuxtConfig({
|
||||
css: [
|
||||
join(currentDir, './assets/main.css'),
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
### Install Dependencies
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
extends: [
|
||||
['github:user/layer', { install: true }],
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
### Disable Layer Modules
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
extends: ['./base-layer'],
|
||||
// Disable modules from layer
|
||||
image: false, // Disables @nuxt/image
|
||||
pinia: false, // Disables @pinia/nuxt
|
||||
})
|
||||
```
|
||||
|
||||
## Starter Template
|
||||
|
||||
Create a new layer:
|
||||
|
||||
```bash
|
||||
npx nuxi init --template layer my-layer
|
||||
```
|
||||
|
||||
## Example: Theme Layer
|
||||
|
||||
```

|
||||
})
|
||||
|
||||
// consuming-app/app/app.config.ts
|
||||
export default defineAppConfig({
|
||||
theme: {
|
||||
primaryColor: '#ff0000', // Override
|
||||
},
|
||||
})
|

# Module Authoring
|
||||
|
||||
This guide covers creating publishable Nuxt modules with proper structure, type safety, and best practices.
|
||||
|
||||
## Module Structure
|
||||
|
||||
Recommended structure for a publishable module:
|
||||
|
||||
```
|
||||
my-nuxt-module/
|
||||
├── src/
|
||||
│ ├── module.ts # Module entry
|
||||
│ └── runtime/
|
||||
│ ├── components/ # Vue components
|
||||
│ ├── composables/ # Composables
|
||||
│ ├── plugins/ # Nuxt plugins
|
||||
│ └── server/ # Server handlers
|
||||
├── playground/ # Development app
|
||||
├── package.json
|
||||
└── tsconfig.json
|
||||
```
|
||||
|
||||
## Module Definition
|
||||
|
||||
### Basic Module with Type-safe Options
|
||||
|
||||
```ts
|
||||
// src/module.ts
|
||||
import { defineNuxtModule, createResolver, addPlugin, addComponent, addImports } from '@nuxt/kit'
|
||||
|
||||
export interface ModuleOptions {
|
||||
prefix?: string
|
||||
apiKey: string
|
||||
enabled?: boolean
|
||||
}
|
||||
|
||||
export default defineNuxtModule<ModuleOptions>({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
configKey: 'myModule',
|
||||
compatibility: {
|
||||
nuxt: '>=3.0.0',
|
||||
},
|
||||
},
|
||||
defaults: {
|
||||
prefix: 'My',
|
||||
enabled: true,
|
||||
},
|
||||
setup(options, nuxt) {
|
||||
if (!options.enabled) return
|
||||
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Module setup logic here
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Using `.with()` for Strict Type Inference
|
||||
|
||||
When you need TypeScript to infer that default values are always present:
|
||||
|
||||
```ts
|
||||
import { defineNuxtModule } from '@nuxt/kit'
|
||||
|
||||
interface ModuleOptions {
|
||||
apiKey: string
|
||||
baseURL: string
|
||||
timeout?: number
|
||||
}
|
||||
|
||||
export default defineNuxtModule<ModuleOptions>().with({
|
||||
meta: {
|
||||
name: '@nuxtjs/my-api',
|
||||
configKey: 'myApi',
|
||||
},
|
||||
defaults: {
|
||||
baseURL: 'https://api.example.com',
|
||||
timeout: 5000,
|
||||
},
|
||||
setup(resolvedOptions, nuxt) {
|
||||
// resolvedOptions.baseURL is guaranteed to be string (not undefined)
|
||||
// resolvedOptions.timeout is guaranteed to be number (not undefined)
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Adding Runtime Assets
|
||||
|
||||
### Components
|
||||
|
||||
```ts
|
||||
import { addComponent, addComponentsDir, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Single component
|
||||
addComponent({
|
||||
name: 'MyButton',
|
||||
filePath: resolve('./runtime/components/MyButton.vue'),
|
||||
})
|
||||
|
||||
// Component directory with prefix
|
||||
addComponentsDir({
|
||||
path: resolve('./runtime/components'),
|
||||
prefix: 'My',
|
||||
pathPrefix: false,
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Composables and Auto-imports
|
||||
|
||||
```ts
|
||||
import { addImports, addImportsDir, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Single import
|
||||
addImports({
|
||||
name: 'useMyUtil',
|
||||
from: resolve('./runtime/composables/useMyUtil'),
|
||||
})
|
||||
|
||||
// Directory of composables
|
||||
addImportsDir(resolve('./runtime/composables'))
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Plugins
|
||||
|
||||
```ts
|
||||
import { addPlugin, addPluginTemplate, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup(options) {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Static plugin file
|
||||
addPlugin({
|
||||
src: resolve('./runtime/plugins/myPlugin'),
|
||||
mode: 'client', // 'client', 'server', or 'all'
|
||||
})
|
||||
|
||||
// Dynamic plugin with generated code
|
||||
addPluginTemplate({
|
||||
filename: 'my-module-plugin.mjs',
|
||||
getContents: () => `
|
||||
import { defineNuxtPlugin } from '#app/nuxt'
|
||||
|
||||
export default defineNuxtPlugin({
|
||||
name: 'my-module',
|
||||
setup() {
|
||||
const config = ${JSON.stringify(options)}
|
||||
// Plugin logic
|
||||
}
|
||||
})`,
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Server Extensions
|
||||
|
||||
### Server Handlers
|
||||
|
||||
```ts
|
||||
import { addServerHandler, addServerScanDir, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Single handler
|
||||
addServerHandler({
|
||||
route: '/api/my-endpoint',
|
||||
handler: resolve('./runtime/server/api/my-endpoint'),
|
||||
})
|
||||
|
||||
// Scan entire server directory (api/, routes/, middleware/, utils/)
|
||||
addServerScanDir(resolve('./runtime/server'))
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Server Composables
|
||||
|
||||
```ts
|
||||
import { addServerImports, addServerImportsDir, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Single server import
|
||||
addServerImports({
|
||||
name: 'useServerUtil',
|
||||
from: resolve('./runtime/server/utils/useServerUtil'),
|
||||
})
|
||||
|
||||
// Server composables directory
|
||||
addServerImportsDir(resolve('./runtime/server/composables'))
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Nitro Plugin
|
||||
|
||||
```ts
|
||||
import { addServerPlugin, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
addServerPlugin(resolve('./runtime/server/plugin'))
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// runtime/server/plugin.ts
|
||||
import { defineNitroPlugin } from 'nitropack/runtime'
|
||||
|
||||
export default defineNitroPlugin((nitroApp) => {
|
||||
nitroApp.hooks.hook('request', (event) => {
|
||||
console.log('Request:', event.path)
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## Templates and Virtual Files
|
||||
|
||||
### Generate Virtual Files
|
||||
|
||||
```ts
|
||||
import { addTemplate, addTypeTemplate, addServerTemplate, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Client/build virtual file (accessible via #build/my-config.mjs)
|
||||
addTemplate({
|
||||
filename: 'my-config.mjs',
|
||||
getContents: () => `export default ${JSON.stringify(options)}`,
|
||||
})
|
||||
|
||||
// Type declarations
|
||||
addTypeTemplate({
|
||||
filename: 'types/my-module.d.ts',
|
||||
getContents: () => `
|
||||
declare module '#my-module' {
|
||||
export interface Config {
|
||||
apiKey: string
|
||||
}
|
||||
}`,
|
||||
})
|
||||
|
||||
// Nitro virtual file (accessible in server routes)
|
||||
addServerTemplate({
|
||||
filename: '#my-module/config.mjs',
|
||||
getContents: () => `export const config = ${JSON.stringify(options)}`,
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Access Virtual Files
|
||||
|
||||
```ts
|
||||
// In runtime plugin
|
||||
// @ts-expect-error - virtual file
|
||||
import config from '#build/my-config.mjs'
|
||||
|
||||
// In server routes
|
||||
import { config } from '#my-module/config.js'
|
||||
```
|
||||
|
||||
## Extending Pages and Routes
|
||||
|
||||
```ts
|
||||
import { extendPages, extendRouteRules, addRouteMiddleware, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Add pages
|
||||
extendPages((pages) => {
|
||||
pages.push({
|
||||
name: 'my-page',
|
||||
path: '/my-route',
|
||||
file: resolve('./runtime/pages/MyPage.vue'),
|
||||
})
|
||||
})
|
||||
|
||||
// Add route rules (caching, redirects, etc.)
|
||||
extendRouteRules('/api/**', {
|
||||
cache: { maxAge: 60 },
|
||||
})
|
||||
|
||||
// Add middleware
|
||||
addRouteMiddleware({
|
||||
name: 'my-middleware',
|
||||
path: resolve('./runtime/middleware/myMiddleware'),
|
||||
global: true,
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Module Dependencies
|
||||
|
||||
Declare dependencies on other modules with version constraints:
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
},
|
||||
moduleDependencies: {
|
||||
'@nuxtjs/tailwindcss': {
|
||||
version: '>=6.0.0',
|
||||
// Set defaults (user can override)
|
||||
defaults: {
|
||||
exposeConfig: true,
|
||||
},
|
||||
// Force specific options
|
||||
overrides: {
|
||||
viewer: false,
|
||||
},
|
||||
},
|
||||
'@nuxtjs/i18n': {
|
||||
optional: true, // Won't fail if not installed
|
||||
defaults: {
|
||||
defaultLocale: 'en',
|
||||
},
|
||||
},
|
||||
},
|
||||
setup() {
|
||||
// Dependencies are guaranteed to be set up before this runs
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Dynamic Dependencies
|
||||
|
||||
```ts
|
||||
moduleDependencies(nuxt) {
|
||||
const deps: Record<string, any> = {
|
||||
'@nuxtjs/tailwindcss': { version: '>=6.0.0' },
|
||||
}
|
||||
|
||||
if (nuxt.options.ssr) {
|
||||
deps['@nuxtjs/html-validator'] = { optional: true }
|
||||
}
|
||||
|
||||
return deps
|
||||
}
|
||||
```
|
||||
|
||||
## Lifecycle Hooks
|
||||
|
||||
Requires `meta.name` and `meta.version`:
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
version: '1.2.0',
|
||||
},
|
||||
onInstall(nuxt) {
|
||||
// First-time setup
|
||||
console.log('Module installed for the first time')
|
||||
},
|
||||
onUpgrade(nuxt, options, previousVersion) {
|
||||
// Version upgrade migrations
|
||||
console.log(`Upgrading from ${previousVersion}`)
|
||||
},
|
||||
setup(options, nuxt) {
|
||||
// Regular setup runs every build
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Extending Configuration
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
// Add CSS
|
||||
nuxt.options.css.push('my-module/styles.css')
|
||||
|
||||
// Add runtime config
|
||||
nuxt.options.runtimeConfig.public.myModule = {
|
||||
apiUrl: options.apiUrl,
|
||||
}
|
||||
|
||||
// Extend Vite config
|
||||
nuxt.options.vite.optimizeDeps ||= {}
|
||||
nuxt.options.vite.optimizeDeps.include ||= []
|
||||
nuxt.options.vite.optimizeDeps.include.push('some-package')
|
||||
|
||||
// Add build transpile
|
||||
nuxt.options.build.transpile.push('my-package')
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Using Hooks
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
// Declarative hooks
|
||||
hooks: {
|
||||
'components:dirs': (dirs) => {
|
||||
dirs.push({ path: '~/extra' })
|
||||
},
|
||||
},
|
||||
|
||||
setup(options, nuxt) {
|
||||
// Programmatic hooks
|
||||
nuxt.hook('pages:extend', (pages) => {
|
||||
// Modify pages
|
||||
})
|
||||
|
||||
nuxt.hook('imports:extend', (imports) => {
|
||||
imports.push({ name: 'myHelper', from: 'my-package' })
|
||||
})
|
||||
|
||||
nuxt.hook('nitro:config', (config) => {
|
||||
// Modify Nitro config
|
||||
})
|
||||
|
||||
nuxt.hook('vite:extendConfig', (config) => {
|
||||
// Modify Vite config
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Path Resolution
|
||||
|
||||
```ts
|
||||
import { createResolver, resolvePath, findPath } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
async setup(options, nuxt) {
|
||||
// Resolver relative to module
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
const pluginPath = resolve('./runtime/plugin')
|
||||
|
||||
// Resolve with extensions and aliases
|
||||
const entrypoint = await resolvePath('@some/package')
|
||||
|
||||
// Find first existing file
|
||||
const configPath = await findPath([
|
||||
resolve('./config.ts'),
|
||||
resolve('./config.js'),
|
||||
])
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Module Package.json
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "my-nuxt-module",
|
||||
"version": "1.0.0",
|
||||
"type": "module",
|
||||
"exports": {
|
||||
".": {
|
||||
"import": "./dist/module.mjs",
|
||||
"require": "./dist/module.cjs"
|
||||
}
|
||||
},
|
||||
"main": "./dist/module.cjs",
|
||||
"module": "./dist/module.mjs",
|
||||
"types": "./dist/types.d.ts",
|
||||
"files": ["dist"],
|
||||
"scripts": {
|
||||
"dev": "nuxi dev playground",
|
||||
"build": "nuxt-module-build build",
|
||||
"prepare": "nuxt-module-build build --stub"
|
||||
},
|
||||
"dependencies": {
|
||||
"@nuxt/kit": "^3.0.0"
|
||||
},
|
||||
"devDependencies": {
|
||||
"@nuxt/module-builder": "latest",
|
||||
"nuxt": "^3.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Disabling Modules
|
||||
|
||||
Users can disable a module via config key:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
// Disable entirely
|
||||
myModule: false,
|
||||
|
||||
// Or with options
|
||||
myModule: {
|
||||
enabled: false,
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Development Workflow
|
||||
|
||||
1. **Create module**: `npx nuxi init -t module my-module`
|
||||
2. **Develop**: `npm run dev` (runs playground)
|
||||
3. **Build**: `npm run build`
|
||||
4. **Test**: `npm run test`
|
||||
|
||||
## Best Practices
|
||||
|
||||
- Use `createResolver(import.meta.url)` for all path resolution
|
||||
- Prefix components to avoid naming conflicts
|
||||
- Make options type-safe with `ModuleOptions` interface
|
||||
- Use `moduleDependencies` instead of `installModule`
|
||||
- Provide sensible defaults for all options
|
||||
- Add compatibility requirements in `meta.compatibility`
|
||||
- Use virtual files for dynamic configuration
|
||||
- Separate client/server plugins appropriately

# Data Fetching Best Practices
|
||||
|
||||
Effective data fetching patterns for SSR-friendly, performant Nuxt applications.
|
||||
|
||||
## Choose the Right Tool
|
||||
|
||||
| Scenario | Use |
|
||||
|----------|-----|
|
||||
| Component initial data | `useFetch` or `useAsyncData` |
|
||||
| User interactions (clicks, forms) | `$fetch` |
|
||||
| Third-party SDK/API | `useAsyncData` with custom function |
|
||||
| Multiple parallel requests | `useAsyncData` with `Promise.all` |
|
||||
|
||||
## Await vs Non-Await Usage
|
||||
|
||||
The `await` keyword controls whether data fetching **blocks navigation**:
|
||||
|
||||
### With `await` - Blocking Navigation
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Navigation waits until data is fetched (uses Vue Suspense)
|
||||
const { data } = await useFetch('/api/posts')
|
||||
// data.value is available immediately after this line
|
||||
</script>
|
||||
```
|
||||
|
||||
- **Server**: Fetches data and includes it in the payload
|
||||
- **Client hydration**: Uses payload data, no re-fetch
|
||||
- **Client navigation**: Blocks until data is ready
|
||||
|
||||
### Without `await` - Non-Blocking (Lazy)
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Navigation proceeds immediately, data fetches in background
|
||||
const { data, status } = useFetch('/api/posts', { lazy: true })
|
||||
// data.value may be undefined initially - check status!
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div v-if="status === 'pending'">Loading...</div>
|
||||
<div v-else>{{ data }}</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
Equivalent to using `useLazyFetch`:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, status } = useLazyFetch('/api/posts')
|
||||
</script>
|
||||
```
|
||||
|
||||
### When to Use Each
|
||||
|
||||
| Pattern | Use Case |
|
||||
|---------|----------|
|
||||
| `await useFetch()` | Critical data needed for SEO/initial render |
|
||||
| `useFetch({ lazy: true })` | Non-critical data, better perceived performance |
|
||||
| `await useLazyFetch()` | Same as lazy, await only ensures initialization |
|
||||
|
||||
## Avoid Double Fetching
|
||||
|
||||
### ❌ Wrong: Using $fetch Alone in Setup
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// This fetches TWICE: once on server, once on client
|
||||
const data = await $fetch('/api/posts')
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Correct: Use useFetch
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Fetches on server, hydrates on client (no double fetch)
|
||||
const { data } = await useFetch('/api/posts')
|
||||
</script>
|
||||
```
|
||||
|
||||
## Use Explicit Cache Keys
|
||||
|
||||
### ❌ Avoid: Auto-generated Keys
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Key is auto-generated from file/line - can cause issues
|
||||
const { data } = await useAsyncData(() => fetchPosts())
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Better: Explicit Keys
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Explicit key for predictable caching
|
||||
const { data } = await useAsyncData(
|
||||
'posts',
|
||||
() => fetchPosts(),
|
||||
)
|
||||
|
||||
// Dynamic keys for parameterized data
|
||||
const route = useRoute()
|
||||
const { data: post } = await useAsyncData(
|
||||
`post-${route.params.id}`,
|
||||
() => fetchPost(route.params.id),
|
||||
)
|
||||
</script>
|
||||
```
|
||||
|
||||
## Handle Loading States Properly
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, status, error } = await useFetch('/api/posts')
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div v-if="status === 'pending'">
|
||||
<SkeletonLoader />
|
||||
</div>
|
||||
<div v-else-if="error">
|
||||
<ErrorMessage :error="error" />
|
||||
</div>
|
||||
<div v-else>
|
||||
<PostList :posts="data" />
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Use Lazy Fetching for Non-critical Data
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const id = useRoute().params.id
|
||||
|
||||
// Critical data - blocks navigation
|
||||
const { data: post } = await useFetch(`/api/posts/${id}`)
|
||||
|
||||
// Non-critical data - doesn't block navigation
|
||||
const { data: comments, status } = useFetch(`/api/posts/${id}/comments`, {
|
||||
lazy: true,
|
||||
})
|
||||
|
||||
// Or use useLazyFetch
|
||||
const { data: related } = useLazyFetch(`/api/posts/${id}/related`)
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<article>
|
||||
<h1>{{ post?.title }}</h1>
|
||||
<p>{{ post?.content }}</p>
|
||||
</article>
|
||||
|
||||
<section v-if="status === 'pending'">Loading comments...</section>
|
||||
<CommentList v-else :comments="comments" />
|
||||
</template>
|
||||
```
|
||||
|
||||
## Minimize Payload Size
|
||||
|
||||
### Use `pick` for Simple Filtering
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data } = await useFetch('/api/users', {
|
||||
// Only include these fields in payload
|
||||
pick: ['id', 'name', 'avatar'],
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Use `transform` for Complex Transformations
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data } = await useFetch('/api/posts', {
|
||||
transform: (posts) => {
|
||||
return posts.map(post => ({
|
||||
id: post.id,
|
||||
title: post.title,
|
||||
excerpt: post.content.slice(0, 100),
|
||||
date: new Date(post.createdAt).toLocaleDateString(),
|
||||
}))
|
||||
},
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Parallel Fetching
|
||||
|
||||
### Fetch Independent Data with useAsyncData
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data } = await useAsyncData(
|
||||
'dashboard',
|
||||
async (_nuxtApp, { signal }) => {
|
||||
const [user, posts, stats] = await Promise.all([
|
||||
$fetch('/api/user', { signal }),
|
||||
$fetch('/api/posts', { signal }),
|
||||
$fetch('/api/stats', { signal }),
|
||||
])
|
||||
return { user, posts, stats }
|
||||
},
|
||||
)
|
||||
</script>
|
||||
```
|
||||
|
||||
### Multiple useFetch Calls
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// These run in parallel automatically
|
||||
const [{ data: user }, { data: posts }] = await Promise.all([
|
||||
useFetch('/api/user'),
|
||||
useFetch('/api/posts'),
|
||||
])
|
||||
</script>
|
||||
```
|
||||
|
||||
## Efficient Refresh Patterns
|
||||
|
||||
### Watch Reactive Dependencies
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const page = ref(1)
|
||||
const category = ref('all')
|
||||
|
||||
const { data } = await useFetch('/api/posts', {
|
||||
query: { page, category },
|
||||
// Auto-refresh when these change
|
||||
watch: [page, category],
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Manual Refresh
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, refresh, status } = await useFetch('/api/posts')
|
||||
|
||||
async function refreshPosts() {
|
||||
await refresh()
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
### Conditional Fetching
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const userId = ref<string | null>(null)
|
||||
|
||||
const { data, execute } = useFetch(() => `/api/users/${userId.value}`, {
|
||||
immediate: false, // Don't fetch until userId is set
|
||||
})
|
||||
|
||||
// Later, when userId is available
|
||||
function loadUser(id: string) {
|
||||
userId.value = id
|
||||
execute()
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
## Server-only Fetching
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Only fetch on server, skip on client navigation
|
||||
const { data } = await useFetch('/api/static-content', {
|
||||
server: true,
|
||||
lazy: true,
|
||||
getCachedData: (key, nuxtApp) => nuxtApp.payload.data[key],
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, error, refresh } = await useFetch('/api/posts')
|
||||
|
||||
// Watch for errors if need event-like handling
|
||||
watch(error, (err) => {
|
||||
if (err) {
|
||||
console.error('Fetch failed:', err)
|
||||
// Show toast, redirect, etc.
|
||||
}
|
||||
}, { immediate: true })
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div v-if="error">
|
||||
<p>Failed to load: {{ error.message }}</p>
|
||||
<button @click="refresh()">Retry</button>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Shared Data Across Components
|
||||
|
||||
```vue
|
||||
<!-- ComponentA.vue -->
|
||||
<script setup lang="ts">
|
||||
const { data } = await useFetch('/api/user', { key: 'current-user' })
|
||||
</script>
|
||||
|
||||
<!-- ComponentB.vue -->
|
||||
<script setup lang="ts">
|
||||
// Access cached data without refetching
|
||||
const { data: user } = useNuxtData('current-user')
|
||||
|
||||
// Or refresh it
|
||||
const { refresh } = await useFetch('/api/user', { key: 'current-user' })
|
||||
</script>
|
||||
```
|
||||
|
||||
## Avoid useAsyncData for Side Effects
|
||||
|
||||
### ❌ Wrong: Side Effects in useAsyncData
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Don't trigger Pinia actions or side effects
|
||||
await useAsyncData(() => store.fetchUser()) // Can cause issues
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Correct: Use callOnce for Side Effects
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
await callOnce(async () => {
|
||||
await store.fetchUser()
|
||||
})
|
||||
</script>
|
||||
```

# SSR Best Practices
|
||||
|
||||
Patterns for avoiding common SSR pitfalls: context leaks, hydration mismatches, and composable errors.
|
||||
|
||||
## The "Nuxt Instance Unavailable" Error
|
||||
|
||||
This error occurs when calling Nuxt composables outside the proper context.
|
||||
|
||||
### ❌ Wrong: Composable Outside Setup
|
||||
|
||||
```ts
|
||||
// composables/bad.ts
|
||||
// Called at module level - no Nuxt context!
|
||||
const config = useRuntimeConfig()
|
||||
|
||||
export function useMyComposable() {
|
||||
return config.public.apiBase
|
||||
}
|
||||
```
|
||||
|
||||
### ✅ Correct: Composable Inside Function
|
||||
|
||||
```ts
|
||||
// composables/good.ts
|
||||
export function useMyComposable() {
|
||||
// Called inside the composable - has context
|
||||
const config = useRuntimeConfig()
|
||||
return config.public.apiBase
|
||||
}
|
||||
```
|
||||
|
||||
### Valid Contexts for Composables
|
||||
|
||||
Nuxt composables work in:
|
||||
- `<script setup>` blocks
|
||||
- `setup()` function
|
||||
- `defineNuxtPlugin()` callbacks
|
||||
- `defineNuxtRouteMiddleware()` callbacks
|
||||
|
||||
```ts
|
||||
// ✅ Plugin
|
||||
export default defineNuxtPlugin(() => {
|
||||
const config = useRuntimeConfig() // Works
|
||||
})
|
||||
|
||||
// ✅ Middleware
|
||||
export default defineNuxtRouteMiddleware(() => {
|
||||
const route = useRoute() // Works
|
||||
})
|
||||
```
|
||||
|
||||
## Avoid State Leaks Between Requests
|
||||
|
||||
### ❌ Wrong: Module-level State
|
||||
|
||||
```ts
|
||||
// composables/bad.ts
|
||||
// This state is SHARED between all requests on server!
|
||||
const globalState = ref({ user: null })
|
||||
|
||||
export function useUser() {
|
||||
return globalState
|
||||
}
|
||||
```
|
||||
|
||||
### ✅ Correct: Use useState
|
||||
|
||||
```ts
|
||||
// composables/good.ts
|
||||
export function useUser() {
|
||||
// useState creates request-isolated state
|
||||
return useState('user', () => ({ user: null }))
|
||||
}
|
||||
```
|
||||
|
||||
### Why This Matters
|
||||
|
||||
On the server, module-level state persists across requests, causing:
|
||||
- Data leaking between users
|
||||
- Security vulnerabilities
|
||||
- Memory leaks
|
||||
|
||||
## Hydration Mismatch Prevention
|
||||
|
||||
Hydration mismatches occur when server HTML differs from client render.
|
||||
|
||||
### ❌ Wrong: Browser APIs in Setup
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
// localStorage doesn't exist on server!
|
||||
const theme = localStorage.getItem('theme') || 'light'
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Correct: Use SSR-safe Alternatives
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
// useCookie works on both server and client
|
||||
const theme = useCookie('theme', { default: () => 'light' })
|
||||
</script>
|
||||
```
|
||||
|
||||
### ❌ Wrong: Random/Time-based Values
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div>{{ Math.random() }}</div>
|
||||
<div>{{ new Date().toLocaleTimeString() }}</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### ✅ Correct: Use useState for Consistency
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
// Value is generated once on server, hydrated on client
|
||||
const randomValue = useState('random', () => Math.random())
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>{{ randomValue }}</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### ❌ Wrong: Conditional Rendering on Client State
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- window doesn't exist on server -->
|
||||
<div v-if="window?.innerWidth > 768">Desktop</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### ✅ Correct: Use CSS or ClientOnly
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- CSS media queries work on both -->
|
||||
<div class="hidden md:block">Desktop</div>
|
||||
<div class="md:hidden">Mobile</div>
|
||||
|
||||
<!-- Or use ClientOnly for JS-dependent rendering -->
|
||||
<ClientOnly>
|
||||
<ResponsiveComponent />
|
||||
<template #fallback>Loading...</template>
|
||||
</ClientOnly>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Browser-only Code
|
||||
|
||||
### Use `import.meta.client`
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
if (import.meta.client) {
|
||||
// Only runs in browser
|
||||
window.addEventListener('scroll', handleScroll)
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
### Use `onMounted` for DOM Access
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
const el = ref<HTMLElement>()
|
||||
|
||||
onMounted(() => {
|
||||
// Safe - only runs on client after hydration
|
||||
el.value?.focus()
|
||||
initThirdPartyLib()
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Dynamic Imports for Browser Libraries
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
onMounted(async () => {
|
||||
const { Chart } = await import('chart.js')
|
||||
new Chart(canvas.value, config)
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Server-only Code
|
||||
|
||||
### Use `import.meta.server`
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
if (import.meta.server) {
|
||||
// Only runs on server
|
||||
const secrets = useRuntimeConfig().apiSecret
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
### Server Components
|
||||
|
||||
```vue
|
||||
<!-- components/ServerData.server.vue -->
|
||||
<script setup>
|
||||
// This entire component only runs on server
|
||||
const data = await fetchSensitiveData()
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>{{ data }}</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Async Composable Patterns
|
||||
|
||||
### ❌ Wrong: Await Before Composable
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
await someAsyncOperation()
|
||||
const route = useRoute() // May fail - context lost after await
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Correct: Get Context First
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
// Get all composables before any await
|
||||
const route = useRoute()
|
||||
const config = useRuntimeConfig()
|
||||
|
||||
await someAsyncOperation()
|
||||
// Now safe to use route and config
|
||||
</script>
|
||||
```
|
||||
|
||||
## Plugin Best Practices
|
||||
|
||||
### Client-only Plugins
|
||||
|
||||
```ts
|
||||
// plugins/analytics.client.ts
|
||||
export default defineNuxtPlugin(() => {
|
||||
// Only runs on client
|
||||
initAnalytics()
|
||||
})
|
||||
```
|
||||
|
||||
### Server-only Plugins
|
||||
|
||||
```ts
|
||||
// plugins/server-init.server.ts
|
||||
export default defineNuxtPlugin(() => {
|
||||
// Only runs on server
|
||||
initServerConnections()
|
||||
})
|
||||
```
|
||||
|
||||
### Provide/Inject Pattern
|
||||
|
||||
```ts
|
||||
// plugins/api.ts
|
||||
export default defineNuxtPlugin(() => {
|
||||
const api = createApiClient()
|
||||
|
||||
return {
|
||||
provide: {
|
||||
api,
|
||||
},
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
const { $api } = useNuxtApp()
|
||||
const data = await $api.get('/users')
|
||||
</script>
|
||||
```
|
||||
|
||||
## Third-party Library Integration
|
||||
|
||||
### ❌ Wrong: Import at Top Level
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
import SomeLibrary from 'browser-only-lib' // Breaks SSR
|
||||
</script>
|
||||
```
|
||||
|
||||
### ✅ Correct: Dynamic Import
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
let library: typeof import('browser-only-lib')
|
||||
|
||||
onMounted(async () => {
|
||||
library = await import('browser-only-lib')
|
||||
library.init()
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Use ClientOnly Component
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<ClientOnly>
|
||||
<BrowserOnlyComponent />
|
||||
<template #fallback>
|
||||
<div class="skeleton">Loading...</div>
|
||||
</template>
|
||||
</ClientOnly>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Debugging SSR Issues
|
||||
|
||||
### Check Rendering Context
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
console.log('Server:', import.meta.server)
|
||||
console.log('Client:', import.meta.client)
|
||||
</script>

### Use Nuxt DevTools
|
||||
|
||||
DevTools shows payload data and hydration state.
|
||||
|
||||

## Building
|
||||
|
||||
### Production Build
|
||||
|
||||
```bash
|
||||
# Build for production
|
||||
npx nuxt build
|
||||
|
||||
# Build with prerendering
|
||||
npx nuxt build --prerender
|
||||
|
||||
# Build with specific preset
|
||||
npx nuxt build --preset node-server
|
||||
npx nuxt build --preset cloudflare-pages
|
||||
npx nuxt build --preset vercel
|
||||
|
||||
# Build with environment
|
||||
npx nuxt build --envName staging
|
||||
```
|
||||
|
||||
Output is created in `.output/` directory.
|
||||
|
||||
### Static Generation
|
||||
|
||||
```bash
|
||||
# Generate static site (prerenders all routes)
|
||||
npx nuxt generate
|
||||
```
|
||||
|
||||
Equivalent to `nuxt build --prerender`. Creates static HTML files for deployment to static hosting.
|
||||
|
||||
### Preview Production Build
|
||||
|
||||
```bash
|
||||
# Preview after build
|
||||

||||
|
||||
# Custom port
|
||||
npx nuxt preview --port 4000
|
||||
```
|
||||
|
||||
## Utilities
|
||||
|
||||
### Prepare (Type Generation)
|
||||
|
||||
```bash
|
||||
# Generate TypeScript types and .nuxt directory
|
||||
npx nuxt prepare
|
||||
```
|
||||
|
||||
Run after cloning or when types are missing.
|
||||
|
||||
### Type Check
|
||||
|
||||
```bash
|
||||
# Run TypeScript type checking
|
||||
npx nuxt typecheck
|
||||
```
|
||||
|
||||
### Analyze Bundle
|
||||
|
||||
```bash
|
||||
# Analyze production bundle
|
||||
npx nuxt analyze
|
||||
```
|
||||
|
||||
Opens visual bundle analyzer.
|
||||
|
||||
### Cleanup
|
||||
|
||||
```bash
|
||||
# Remove generated files (.nuxt, .output, node_modules/.cache)
|
||||
npx nuxt cleanup
|
||||
```
|
||||
|
||||
### Info
|
||||
|
||||
```bash
|
||||
# Show environment info (useful for bug reports)
|
||||
npx nuxt info
|
||||
```
|
||||
|
||||
### Upgrade
|
||||
|
||||
```bash
|
||||
# Upgrade Nuxt to latest version
|
||||
npx nuxt upgrade
|
||||
|
||||
# Upgrade to nightly release
|
||||
npx nuxt upgrade --nightly
|
||||
```
|
||||
|
||||
## Module Commands
|
||||
|
||||
### Add Module
|
||||
|
||||
```bash
|
||||
# Add a Nuxt module
|
||||
npx nuxt module add @nuxt/ui
|
||||
npx nuxt module add @nuxt/image
|
||||
```
|
||||
|
||||
Installs and adds to `nuxt.config.ts`.
|
||||
|
||||
### Build Module (for module authors)
|
||||
|
||||
```bash
|
||||
# Build a Nuxt module
|
||||
npx nuxt build-module
|
||||
```
|
||||
|
||||
## DevTools
|
||||
|
||||
```bash
|
||||
# Enable DevTools globally
|
||||
npx nuxt devtools enable
|
||||
|
||||
# Disable DevTools
|
||||
npx nuxt devtools disable
|
||||
```
|
||||
|
||||
## Common Workflows
|
||||
|
||||
### Development
|
||||
|
||||
```bash
|
||||
# Install dependencies and start dev
|
||||
pnpm install
|
||||
pnpm dev # or npx nuxt dev
|
||||
```
|
||||
|
||||
### Production Deployment
|
||||
|
||||
```bash
|
||||
# Build and preview locally
|
||||
pnpm build
|
||||
pnpm preview
|
||||
|
||||
# Or for static hosting
|
||||
pnpm generate
|
||||
```
|
||||
|
||||
### After Cloning
|
||||
|
||||
```bash
|
||||
# Install deps and prepare types
|
||||
pnpm install
|
||||
npx nuxt prepare
|
||||
```
|
||||
|
||||
## Environment-specific Builds
|
||||
|
||||
```bash
|
||||
# Development build
|
||||
npx nuxt build --envName development
|
||||
|
||||
# Staging build
|
||||
npx nuxt build --envName staging
|
||||
|
||||
# Production build (default)
|
||||
npx nuxt build --envName production
|
||||
```
|
||||
|
||||
Corresponds to `$development`, `$env.staging`, `$production` in `nuxt.config.ts`.
|
||||
|
||||
## Layer Extension
|
||||
|
||||
```bash
|
||||
# Dev with additional layer
|
||||
npx nuxt dev --extends ./base-layer
|
||||
|
||||
# Build with layer
|
||||
npx nuxt build --extends ./base-layer
|
||||
```

# Nuxt Configuration
|
||||
|
||||
Nuxt uses configuration files to customize application behavior. The main configuration options are `nuxt.config.ts` for build-time settings and `app.config.ts` for runtime settings.
|
||||
|
||||
## nuxt.config.ts
|
||||
|
||||
The main configuration file at the root of your project:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
// Configuration options
|
||||
devtools: { enabled: true },
|
||||
modules: ['@nuxt/ui'],
|
||||
})
|
||||
```
|
||||
|
||||
### Environment Overrides
|
||||
|
||||
Configure environment-specific settings:
|
||||
|
||||
```ts
|
||||
export default defineNuxtConfig({
|
||||
$production: {
|
||||
routeRules: {
|
||||
'/**': { isr: true },
|
||||
},
|
||||
},
|
||||
$development: {
|
||||
// Development-specific config
|
||||
},
|
||||
$env: {
|
||||
staging: {
|
||||
// Staging environment config
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Use `--envName` flag to select environment: `nuxt build --envName staging`
|
||||
|
||||
## Runtime Config
|
||||
|
||||
For values that need to be overridden via environment variables:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
runtimeConfig: {
|
||||
// Server-only keys
|
||||
apiSecret: '123',
|
||||
// Keys within public are exposed to client
|
||||
public: {
|
||||
apiBase: '/api',
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Override with environment variables:
|
||||
|
||||
```ini
|
||||
# .env
|
||||
NUXT_API_SECRET=api_secret_token
|
||||
NUXT_PUBLIC_API_BASE=https://api.example.com
|
||||
```
|
||||
|
||||
Access in components/composables:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const config = useRuntimeConfig()
|
||||
// Server: config.apiSecret, config.public.apiBase
|
||||
// Client: config.public.apiBase only
|
||||
</script>
|
||||
```
|
||||
|
||||
## App Config
|
||||
|
||||
For public tokens determined at build time (not overridable via env vars):
|
||||
|
||||
```ts
|
||||
// app/app.config.ts
|
||||
export default defineAppConfig({
|
||||
title: 'Hello Nuxt',
|
||||
theme: {
|
||||
dark: true,
|
||||
colors: {
|
||||
primary: '#ff0000',
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Access in components:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const appConfig = useAppConfig()
|
||||
</script>
|
||||
```
|
||||
|
||||
## runtimeConfig vs app.config
|
||||
|
||||
| Feature | runtimeConfig | app.config |
|
||||
|---------|--------------|------------|
|
||||
| Client-side | Hydrated | Bundled |
|
||||
| Environment variables | Yes | No |
|
||||
| Reactive | Yes | Yes |
|
||||
| Hot module replacement | No | Yes |
|
||||
| Non-primitive JS types | No | Yes |
|
||||
|
||||
**Use runtimeConfig** for secrets and values that change per environment.
|
||||
**Use app.config** for public tokens, theme settings, and non-sensitive config.
|
||||
|
||||
## External Tool Configuration
|
||||
|
||||
Nuxt uses `nuxt.config.ts` as single source of truth. Configure external tools within it:
|
||||
|
||||
```ts
|
||||
export default defineNuxtConfig({
|
||||
// Nitro configuration
|
||||
nitro: {
|
||||
// nitro options
|
||||
},
|
||||
// Vite configuration
|
||||
vite: {
|
||||
// vite options
|
||||
vue: {
|
||||
// @vitejs/plugin-vue options
|
||||
},
|
||||
},
|
||||
// PostCSS configuration
|
||||
postcss: {
|
||||
// postcss options
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Vue Configuration
|
||||
|
||||
Enable Vue experimental features:
|
||||
|
||||
```ts
|
||||
export default defineNuxtConfig({
|
||||
vue: {
|
||||
propsDestructure: true,
|
||||
},
|
||||
})
|
||||
```

|

# Data Fetching
|
||||
|
||||
Nuxt provides composables for SSR-friendly data fetching that prevent double-fetching and handle hydration.
|
||||
|
||||
## Overview
|
||||
|
||||
- `$fetch` - Basic fetch utility (use for client-side events)
|
||||
- `useFetch` - SSR-safe wrapper around $fetch (use for component data)
|
||||
- `useAsyncData` - SSR-safe wrapper for any async function
|
||||
|
||||
## useFetch
|
||||
|
||||
Primary composable for fetching data in components:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, status, error, refresh, clear } = await useFetch('/api/posts')
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div v-if="status === 'pending'">Loading...</div>
|
||||
<div v-else-if="error">Error: {{ error.message }}</div>
|
||||
<div v-else>
|
||||
<article v-for="post in data" :key="post.id">
|
||||
{{ post.title }}
|
||||
</article>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### With Options
|
||||
|
||||
```ts
|
||||
const { data } = await useFetch('/api/posts', {
|
||||
// Query parameters
|
||||
query: { page: 1, limit: 10 },
|
||||
// Request body (for POST/PUT)
|
||||
body: { title: 'New Post' },
|
||||
// HTTP method
|
||||
method: 'POST',
|
||||
// Only pick specific fields
|
||||
pick: ['id', 'title'],
|
||||
// Transform response
|
||||
transform: (posts) => posts.map(p => ({ ...p, slug: slugify(p.title) })),
|
||||
// Custom key for caching
|
||||
key: 'posts-list',
|
||||
// Don't fetch on server
|
||||
server: false,
|
||||
// Don't block navigation
|
||||
lazy: true,
|
||||
// Don't fetch immediately
|
||||
immediate: false,
|
||||
// Default value
|
||||
default: () => [],
|
||||
})
|
||||
```
|
||||
|
||||
### Reactive Parameters
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const page = ref(1)
|
||||
const { data } = await useFetch('/api/posts', {
|
||||
query: { page }, // Automatically refetches when page changes
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Computed URL
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const id = ref(1)
|
||||
const { data } = await useFetch(() => `/api/posts/${id.value}`)
|
||||
// Refetches when id changes
|
||||
</script>
|
||||
```
|
||||
|
||||
## useAsyncData
|
||||
|
||||
For wrapping any async function:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data, error } = await useAsyncData('user', () => {
|
||||
return myCustomFetch('/user/profile')
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Multiple Requests
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const { data } = await useAsyncData('cart', async () => {
|
||||
const [coupons, offers] = await Promise.all([
|
||||
$fetch('/api/coupons'),
|
||||
$fetch('/api/offers'),
|
||||
])
|
||||
return { coupons, offers }
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## $fetch
|
||||
|
||||
For client-side events (form submissions, button clicks):
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
async function submitForm() {
|
||||
const result = await $fetch('/api/submit', {
|
||||
method: 'POST',
|
||||
body: { name: 'John' },
|
||||
})
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
**Important**: Don't use `$fetch` alone in setup for initial data - it will fetch twice (server + client). Use `useFetch` or `useAsyncData` instead.
|
||||
|
||||
## Return Values
|
||||
|
||||
All composables return:
|
||||
|
||||
| Property | Type | Description |
|
||||
|----------|------|-------------|
|
||||
| `data` | `Ref<T>` | Fetched data |
|
||||
| `error` | `Ref<Error>` | Error if request failed |
|
||||
| `status` | `Ref<'idle' \| 'pending' \| 'success' \| 'error'>` | Request status |
|
||||
| `refresh` | `() => Promise` | Refetch data |
|
||||
| `execute` | `() => Promise` | Alias for refresh |
|
||||
| `clear` | `() => void` | Reset data and error |
|
||||
|
||||
## Lazy Fetching
|
||||
|
||||
Don't block navigation:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Using lazy option
|
||||
const { data, status } = await useFetch('/api/posts', { lazy: true })
|
||||
|
||||
// Or use lazy variants
|
||||
const { data, status } = await useLazyFetch('/api/posts')
|
||||
const { data, status } = await useLazyAsyncData('key', fetchFn)
|
||||
</script>
|
||||
```
|
||||
|
||||
## Refresh & Watch
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const category = ref('tech')
|
||||
|
||||
const { data, refresh } = await useFetch('/api/posts', {
|
||||
query: { category },
|
||||
// Auto-refresh when category changes
|
||||
watch: [category],
|
||||
})
|
||||
|
||||
// Manual refresh
|
||||
const refreshData = () => refresh()
|
||||
</script>
|
||||
```
|
||||
|
||||
## Caching
|
||||
|
||||
Data is cached by key. Share data across components:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// In component A
|
||||
const { data } = await useFetch('/api/user', { key: 'current-user' })
|
||||
|
||||
// In component B - uses cached data
|
||||
const { data } = useNuxtData('current-user')
|
||||
</script>
|
||||
```
|
||||
|
||||
Refresh cached data globally:
|
||||
|
||||
```ts
|
||||
// Refresh specific key
|
||||
await refreshNuxtData('current-user')
|
||||
|
||||
// Refresh all data
|
||||
await refreshNuxtData()
|
||||
|
||||
// Clear cached data
|
||||
clearNuxtData('current-user')
|
||||
```
|
||||
|
||||
## Interceptors
|
||||
|
||||
```ts
|
||||
const { data } = await useFetch('/api/auth', {
|
||||
onRequest({ options }) {
|
||||
options.headers.set('Authorization', `Bearer ${token}`)
|
||||
},
|
||||
onRequestError({ error }) {
|
||||
console.error('Request failed:', error)
|
||||
},
|
||||
onResponse({ response }) {
|
||||
// Process response
|
||||
},
|
||||
onResponseError({ response }) {
|
||||
if (response.status === 401) {
|
||||
navigateTo('/login')
|
||||
}
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Passing Headers (SSR)
|
||||
|
||||
`useFetch` automatically proxies cookies/headers from client to server. For `$fetch`:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const headers = useRequestHeaders(['cookie'])
|
||||
const data = await $fetch('/api/user', { headers })
|
||||
</script>
|
||||
```

|
||||
|
||||
# Deployment
|
||||
|
||||
Nuxt is platform-agnostic thanks to [Nitro](https://nitro.build), its server engine. You can deploy to almost any platform with minimal configuration—Node.js servers, static hosting, serverless functions, or edge networks.
|
||||
|
||||
> **Full list of supported platforms:** https://nitro.build/deploy
|
||||
|
||||
## Deployment Modes
|
||||
|
||||
### Node.js Server
|
||||
|
||||
```bash
|
||||
# Build for Node.js
|
||||
nuxt build
|
||||
|
||||
# Run production server
|
||||
node .output/server/index.mjs
|
||||
```
|
||||
|
||||
Environment variables:
|
||||
- `PORT` or `NITRO_PORT` (default: 3000)
|
||||
- `HOST` or `NITRO_HOST` (default: 0.0.0.0)
|
||||
|
||||
### Static Generation
|
||||
|
||||
```bash
|
||||
# Generate static site
|
||||
nuxt generate
|
||||
```
|
||||
|
||||
Output in `.output/public/` - deploy to any static host.
|
||||
|
||||
### Preset Configuration
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
nitro: {
|
||||
preset: 'vercel', // or 'netlify', 'cloudflare-pages', etc.
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Or via environment variable:
|
||||
|
||||
```bash
|
||||
NITRO_PRESET=vercel nuxt build
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

# Directory Structure
|
||||
|
||||
Nuxt uses conventions-based directory structure. Understanding it is key to effective development.
|
||||
|
||||
## Standard Project Structure
|
||||
|
||||
```
|
||||

|
||||
|
||||
## Key Directories
|
||||
|
||||
### `app/` Directory
|
||||
|
||||
Contains all application code. Can also be at root level (without `app/` folder).
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts - customize source directory
|
||||
export default defineNuxtConfig({
|
||||
srcDir: 'src/', // Change from 'app/' to 'src/'
|
||||
})
|
||||
```
|
||||
|
||||
### `app/components/`
|
||||
|
||||
Vue components auto-imported by name:
|
||||
|
||||
```
|
||||
components/
|
||||
├── Button.vue → <Button />
|
||||
├── Card.vue → <Card />
|
||||
├── base/
|
||||
│ └── Button.vue → <BaseButton />
|
||||
├── ui/
|
||||
│ ├── Input.vue → <UiInput />
|
||||
│ └── Modal.vue → <UiModal />
|
||||
└── TheHeader.vue → <TheHeader />
|
||||
```
|
||||
|
||||
**Lazy loading**: Prefix with `Lazy` for dynamic import:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<LazyHeavyChart v-if="showChart" />
|
||||
</template>
|
||||
```
|
||||
|
||||
**Client/Server only**:
|
||||
|
||||
```
|
||||
components/
|
||||
├── Comments.client.vue → Only rendered on client
|
||||
└── ServerData.server.vue → Only rendered on server
|
||||
```
|
||||
|
||||
### `app/composables/`
|
||||
|
||||
Vue composables auto-imported (top-level files only):
|
||||
|
||||
```
|
||||
composables/
|
||||
├── useAuth.ts → useAuth()
|
||||
├── useFoo.ts → useFoo()
|
||||
└── nested/
|
||||
└── utils.ts → NOT auto-imported
|
||||
```
|
||||
|
||||
Re-export nested composables:
|
||||
|
||||
```ts
|
||||
// composables/index.ts
|
||||
export { useHelper } from './nested/utils'
|
||||
```
|
||||
|
||||
### `app/pages/`

||||
pages/
|
||||
├── index.vue → /

||||
├── [[optional]].vue → /:optional? (optional param)
|
||||
└── (marketing)/ → Route group (not in URL)
|
||||

# Nuxt Modules
|
||||
|
||||
Modules extend Nuxt's core functionality. They run at build time and can add components, composables, plugins, and configuration.
|
||||
|
||||
## Using Modules
|
||||
|
||||
Install and add to `nuxt.config.ts`:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
modules: [
|
||||
// npm package
|
||||
'@nuxt/ui',
|
||||
// Local module
|
||||
'./modules/my-module',
|
||||
// Inline module
|
||||
(options, nuxt) => {
|
||||
console.log('Inline module')
|
||||
},
|
||||
// With options
|
||||
['@nuxt/image', { provider: 'cloudinary' }],
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
## Creating Modules
|
||||
|
||||
### Basic Module
|
||||
|
||||
```ts
|
||||
// modules/my-module.ts
|
||||
export default defineNuxtModule({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
configKey: 'myModule',
|
||||
},
|
||||
defaults: {
|
||||
enabled: true,
|
||||
},
|
||||
setup(options, nuxt) {
|
||||
if (!options.enabled) return
|
||||
|
||||
console.log('My module is running!')
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Adding Components
|
||||
|
||||
```ts
|
||||
// modules/ui/index.ts
|
||||
import { addComponent, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Add single component
|
||||
addComponent({
|
||||
name: 'MyButton',
|
||||
filePath: resolve('./runtime/components/MyButton.vue'),
|
||||
})
|
||||
|
||||
// Add components directory
|
||||
addComponentsDir({
|
||||
path: resolve('./runtime/components'),
|
||||
prefix: 'My',
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Adding Composables
|
||||
|
||||
```ts
|
||||
// modules/utils/index.ts
|
||||
import { addImports, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
// Add auto-imported composable
|
||||
addImports({
|
||||
name: 'useMyUtil',
|
||||
from: resolve('./runtime/composables/useMyUtil'),
|
||||
})
|
||||
|
||||
// Add directory for auto-imports
|
||||
addImportsDir(resolve('./runtime/composables'))
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Adding Plugins
|
||||
|
||||
```ts
|
||||
// modules/analytics/index.ts
|
||||
import { addPlugin, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
addPlugin({
|
||||
src: resolve('./runtime/plugin'),
|
||||
mode: 'client', // 'client', 'server', or 'all'
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Plugin file:
|
||||
|
||||
```ts
|
||||
// modules/analytics/runtime/plugin.ts
|
||||
export default defineNuxtPlugin((nuxtApp) => {
|
||||
nuxtApp.hook('page:finish', () => {
|
||||
console.log('Page loaded')
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
### Adding Server Routes
|
||||
|
||||
```ts
|
||||
// modules/api/index.ts
|
||||
import { addServerHandler, createResolver } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const { resolve } = createResolver(import.meta.url)
|
||||
|
||||
addServerHandler({
|
||||
route: '/api/my-endpoint',
|
||||
handler: resolve('./runtime/server/api/my-endpoint'),
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Extending Config
|
||||
|
||||
```ts
|
||||
// modules/config/index.ts
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
// Add CSS
|
||||
nuxt.options.css.push('my-module/styles.css')
|
||||
|
||||
// Add runtime config
|
||||
nuxt.options.runtimeConfig.public.myModule = {
|
||||
apiUrl: options.apiUrl,
|
||||
}
|
||||
|
||||
// Extend Vite config
|
||||
nuxt.options.vite.optimizeDeps ||= {}
|
||||
nuxt.options.vite.optimizeDeps.include ||= []
|
||||
nuxt.options.vite.optimizeDeps.include.push('some-package')
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Module Hooks
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
setup(options, nuxt) {
|
||||
// Build-time hooks
|
||||
nuxt.hook('modules:done', () => {
|
||||
console.log('All modules loaded')
|
||||
})
|
||||
|
||||
nuxt.hook('components:dirs', (dirs) => {
|
||||
dirs.push({ path: '~/extra-components' })
|
||||
})
|
||||
|
||||
nuxt.hook('pages:extend', (pages) => {
|
||||
pages.push({
|
||||
name: 'custom-page',
|
||||
path: '/custom',
|
||||
file: resolve('./runtime/pages/custom.vue'),
|
||||
})
|
||||
})
|
||||
|
||||
nuxt.hook('imports:extend', (imports) => {
|
||||
imports.push({ name: 'myHelper', from: 'my-package' })
|
||||
})
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Module Options
|
||||
|
||||
Type-safe options with defaults:
|
||||
|
||||
```ts
|
||||
export interface ModuleOptions {
|
||||
apiKey: string
|
||||
enabled?: boolean
|
||||
prefix?: string
|
||||
}
|
||||
|
||||
export default defineNuxtModule<ModuleOptions>({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
configKey: 'myModule',
|
||||
},
|
||||
defaults: {
|
||||
enabled: true,
|
||||
prefix: 'My',
|
||||
},
|
||||
setup(options, nuxt) {
|
||||
// options is typed as ModuleOptions
|
||||
if (!options.apiKey) {
|
||||
console.warn('API key not provided')
|
||||
}
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Usage:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
modules: ['my-module'],
|
||||
myModule: {
|
||||
apiKey: 'xxx',
|
||||
prefix: 'Custom',
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Local Modules
|
||||
|
||||
Place in `modules/` directory:
|
||||
|
||||
```
|
||||
modules/
|
||||
├── my-module/
|
||||
│ ├── index.ts
|
||||
│ └── runtime/
|
||||
│ ├── components/
|
||||
│ ├── composables/
|
||||
│ └── plugin.ts
|
||||
```
|
||||
|
||||
Auto-registered or manually added:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
modules: [
|
||||
'~/modules/my-module', // Explicit
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
## Module Dependencies
|
||||
|
||||
```ts
|
||||
export default defineNuxtModule({
|
||||
meta: {
|
||||
name: 'my-module',
|
||||
},
|
||||
moduleDependencies: {
|
||||
'@nuxt/image': {
|
||||
version: '>=1.0.0',
|
||||
defaults: {
|
||||
provider: 'ipx',
|
||||
},
|
||||
},
|
||||
},
|
||||
setup() {
|
||||
// @nuxt/image is guaranteed to be installed
|
||||
},
|
||||
})
|
||||
```

# Routing
|
||||
|
||||
Nuxt uses file-system routing based on vue-router. Files in `app/pages/` automatically create routes.
|
||||
|
||||
## Basic Routing
|
||||
|
||||
```
|
||||
pages/
|
||||
├── index.vue → /
|
||||
├── about.vue → /about
|
||||
└── posts/
|
||||
├── index.vue → /posts
|
||||
└── [id].vue → /posts/:id
|
||||
```
|
||||
|
||||
## Dynamic Routes
|
||||
|
||||
Use brackets for dynamic segments:
|
||||
|
||||
```
|
||||
pages/
|
||||
├── users/
|
||||
│ └── [id].vue → /users/:id
|
||||
├── posts/
|
||||
│ └── [...slug].vue → /posts/* (catch-all)
|
||||
└── [[optional]].vue → /:optional? (optional param)
|
||||
```
|
||||
|
||||
Access route parameters:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const route = useRoute()
|
||||
// /posts/123 → route.params.id = '123'
|
||||
console.log(route.params.id)
|
||||
</script>
|
||||
```
|
||||
|
||||
## Navigation
|
||||
|
||||
### NuxtLink Component
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<nav>
|
||||
<NuxtLink to="/">Home</NuxtLink>
|
||||
<NuxtLink to="/about">About</NuxtLink>
|
||||
<NuxtLink :to="{ name: 'posts-id', params: { id: 1 } }">Post 1</NuxtLink>
|
||||
</nav>
|
||||
</template>
|
||||
```
|
||||
|
||||
NuxtLink automatically prefetches linked pages when they enter the viewport.
|
||||
|
||||
### Programmatic Navigation
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const router = useRouter()
|
||||
|
||||
function goToPost(id: number) {
|
||||
navigateTo(`/posts/${id}`)
|
||||
// or
|
||||
router.push({ name: 'posts-id', params: { id } })
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
## Route Middleware
|
||||
|
||||
### Named Middleware
|
||||
|
||||
```ts
|
||||
// middleware/auth.ts
|
||||
export default defineNuxtRouteMiddleware((to, from) => {
|
||||
const isAuthenticated = false // Your auth logic
|
||||
|
||||
if (!isAuthenticated) {
|
||||
return navigateTo('/login')
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
Apply to pages:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
definePageMeta({
|
||||
middleware: 'auth',
|
||||
// or multiple: middleware: ['auth', 'admin']
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
### Global Middleware
|
||||
|
||||
Name files with `.global` suffix:
|
||||
|
||||
```ts
|
||||
// middleware/logging.global.ts
|
||||
export default defineNuxtRouteMiddleware((to, from) => {
|
||||
console.log('Navigating to:', to.path)
|
||||
})
|
||||
```
|
||||
|
||||
### Inline Middleware
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
definePageMeta({
|
||||
middleware: [
|
||||
function (to, from) {
|
||||
// Inline middleware logic
|
||||
},
|
||||
],
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Page Meta
|
||||
|
||||
Configure page-level options:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
definePageMeta({
|
||||
title: 'My Page',
|
||||
layout: 'custom',
|
||||
middleware: 'auth',
|
||||
validate: (route) => {
|
||||
// Return false for 404, or object with status/statusText
|
||||
return /^\d+$/.test(route.params.id as string)
|
||||
},
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Route Validation
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
definePageMeta({
|
||||
validate: (route) => {
|
||||
// Must return boolean or object with status
|
||||
return typeof route.params.id === 'string' && /^\d+$/.test(route.params.id)
|
||||
},
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Layouts
|
||||
|
||||
Define layouts in `app/layouts/`:
|
||||
|
||||
```vue
|
||||
<!-- layouts/default.vue -->
|
||||
<template>
|
||||
<div>
|
||||
<header>Header</header>
|
||||
<slot />
|
||||
<footer>Footer</footer>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
```vue
|
||||
<!-- layouts/admin.vue -->
|
||||
<template>
|
||||
<div class="admin">
|
||||
<AdminSidebar />
|
||||
<main>
|
||||
<slot />
|
||||
</main>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
Use in pages:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
definePageMeta({
|
||||
layout: 'admin',
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
Dynamic layout:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const layout = ref('default')
|
||||
|
||||
function enableAdmin() {
|
||||
setPageLayout('admin')
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
## Navigation Hooks
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
onBeforeRouteLeave((to, from) => {
|
||||
// Confirm before leaving
|
||||
const answer = window.confirm('Leave?')
|
||||
if (!answer) return false
|
||||
})
|
||||
|
||||
onBeforeRouteUpdate((to, from) => {
|
||||
// Called when route changes but component is reused
|
||||
})
|
||||
</script>
|
||||
```

# Components Auto-imports
|
||||
|
||||
Nuxt automatically imports Vue components from `app/components/` directory.
|
||||
|
||||
## Basic Auto-imports
|
||||
|
||||
```
|
||||
components/
|
||||
├── Button.vue → <Button />
|
||||
├── Card.vue → <Card />
|
||||
└── AppHeader.vue → <AppHeader />
|
||||
```
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- No imports needed -->
|
||||
<AppHeader />
|
||||
<Card>
|
||||
<Button>Click me</Button>
|
||||
</Card>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Naming Conventions
|
||||
|
||||
### Nested Directory Names
|
||||
|
||||
Component names include directory path:
|
||||
|
||||
```
|
||||
components/
|
||||
├── base/
|
||||
│ └── Button.vue → <BaseButton />
|
||||
├── form/
|
||||
│ ├── Input.vue → <FormInput />
|
||||
│ └── Select.vue → <FormSelect />
|
||||
└── ui/
|
||||
└── modal/
|
||||
└── Dialog.vue → <UiModalDialog />
|
||||
```
|
||||
|
||||
### Disable Path Prefix
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
components: [
|
||||
{
|
||||
path: '~/components',
|
||||
pathPrefix: false, // Use filename only
|
||||
},
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
With `pathPrefix: false`:
|
||||
```
|
||||
components/base/Button.vue → <Button />
|
||||
```
|
||||
|
||||
## Lazy Loading
|
||||
|
||||
Prefix with `Lazy` for dynamic imports:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const showChart = ref(false)
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<!-- Component code loaded only when rendered -->
|
||||
<LazyHeavyChart v-if="showChart" />
|
||||
<button @click="showChart = true">Show Chart</button>
|
||||
</template>
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Reduces initial bundle size
|
||||
- Code-splits component into separate chunk
|
||||
- Loads on-demand
|
||||
|
||||
## Lazy Hydration Strategies
|
||||
|
||||
Control when lazy components become interactive:
|
||||
|
||||
### `hydrate-on-visible`
|
||||
|
||||
Hydrate when component enters viewport:
|
||||
|
||||
```vue
|

|
||||
|

|
||||
|
||||
### `hydrate-never`
|
||||
|
||||

<script setup>
|
||||
function onChartReady() {
|
||||
console.log('Chart is now interactive')
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
## Client/Server Components
|
||||
|
||||
### Client-only (`.client.vue`)
|
||||
|
||||
```
|
||||
components/
|
||||
└── BrowserChart.client.vue
|
||||
```
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- Only rendered in browser -->
|
||||
<BrowserChart />
|
||||
</template>
|
||||
```
|
||||
|
||||
### Server-only (`.server.vue`)
|
||||
|
||||
```
|
||||
components/
|
||||
└── ServerMarkdown.server.vue
|
||||
```
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- Rendered on server, not hydrated -->
|
||||
<ServerMarkdown :content="markdown" />
|
||||
</template>
|
||||
```
|
||||
|
||||
Requires experimental flag:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
experimental: {
|
||||
componentIslands: true,
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Paired Components
|
||||
|
||||
```
|
||||
components/
|
||||
├── Comments.client.vue # Browser version
|
||||
└── Comments.server.vue # SSR version
|
||||
```
|
||||
|
||||
Server version renders during SSR, client version takes over after hydration.
|
||||
|
||||
## Dynamic Components
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import { SomeComponent } from '#components'
|
||||
|
||||
const dynamicComponent = resolveComponent('MyButton')
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<component :is="dynamicComponent" />
|
||||
<component :is="SomeComponent" />
|
||||
</template>
|
||||
```
|
||||
|
||||
## Direct Imports
|
||||
|
||||
Bypass auto-imports when needed:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import { LazyMountainsList, NuxtLink } from '#components'
|
||||
</script>
|
||||
```
|
||||
|
||||
## Custom Directories
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
components: [
|
||||
{ path: '~/components/ui', prefix: 'Ui' },
|
||||
{ path: '~/components/forms', prefix: 'Form' },
|
||||
'~/components', // Default, should come last
|
||||
],
|
||||
})
|
||||
```
|
||||
|
||||
## Global Components
|
||||
|
||||
Register globally (creates async chunks):
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
components: {
|
||||
global: true,
|
||||
dirs: ['~/components'],
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Or use `.global.vue` suffix:
|
||||
|
||||
```
|
||||
components/
|
||||
└── Icon.global.vue → Available globally
|
||||
```
|
||||
|
||||
## Disabling Component Auto-imports
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
components: {
|
||||
dirs: [], // Disable auto-imports
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Library Authors
|
||||
|
||||
Register components from npm package:
|
||||
|
||||
```ts
|
||||
// my-ui-lib/nuxt.ts
|
||||
import { addComponentsDir, createResolver, defineNuxtModule } from '@nuxt/kit'
|
||||
|
||||
export default defineNuxtModule({
|
||||
setup() {
|
||||
const resolver = createResolver(import.meta.url)
|
||||
|
||||
addComponentsDir({
|
||||
path: resolver.resolve('./components'),
|
||||
prefix: 'MyUi',
|
||||
})
|
||||
},
|
||||
})
|
||||
```

# Built-in Components
|
||||
|
||||
Nuxt provides several built-in components for common functionality.
|
||||
|
||||
## NuxtLink
|
||||
|
||||
Optimized link component with prefetching:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- Basic usage -->
|
||||
<NuxtLink to="/about">About</NuxtLink>
|
||||
|
||||
<!-- With route object -->
|
||||
<NuxtLink :to="{ name: 'posts-id', params: { id: 1 } }">Post 1</NuxtLink>
|
||||
|
||||
<!-- External link (opens in new tab) -->
|
||||
<NuxtLink to="https://nuxt.com" external>Nuxt</NuxtLink>
|
||||
|
||||
<!-- Disable prefetching -->
|
||||
<NuxtLink to="/heavy-page" :prefetch="false">Heavy Page</NuxtLink>
|
||||
|
||||
<!-- Replace history instead of push -->
|
||||
<NuxtLink to="/page" replace>Replace</NuxtLink>
|
||||
|
||||
<!-- Custom active class -->
|
||||
<NuxtLink
|
||||
to="/dashboard"
|
||||
active-class="text-primary"
|
||||
exact-active-class="font-bold"
|
||||
>
|
||||
Dashboard
|
||||
</NuxtLink>
|
||||
</template>
|
||||
```
|
||||
|
||||
## NuxtPage
|
||||
|
||||
Renders the current page component (used in layouts):
|
||||
|
||||
```vue
|
||||
<!-- app/app.vue -->
|
||||
<template>
|
||||
<NuxtLayout>
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
```
|
||||
|
||||
With page transitions:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtPage :transition="{ name: 'fade', mode: 'out-in' }" />
|
||||
</template>
|
||||
```
|
||||
|
||||
Pass props to page:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtPage :page-key="route.fullPath" :foobar="123" />
|
||||
</template>
|
||||
```
|
||||
|
||||
## NuxtLayout
|
||||
|
||||
Controls layout rendering:
|
||||
|
||||
```vue
|
||||
<!-- app/app.vue -->
|
||||
<template>
|
||||
<NuxtLayout>
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
```
|
||||
|
||||
Dynamic layout:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtLayout :name="layout">
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
|
||||
<script setup>
|
||||
const layout = computed(() => isAdmin ? 'admin' : 'default')
|
||||
</script>
|
||||
```
|
||||
|
||||
Layout with transitions:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtLayout :transition="{ name: 'slide', mode: 'out-in' }">
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
```
|
||||
|
||||
## NuxtLoadingIndicator
|
||||
|
||||

|
||||
|
||||
```vue
|
||||
<!-- app/app.vue -->

|
||||
color="repeating-linear-gradient(to right, #00dc82 0%, #34cdfe 50%, #0047e1 100%)"
|
||||
:height="3"
|
||||

||||
:throttle="200"
|
||||
/>
|
||||
<NuxtLayout>
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
```
|
||||
|
||||
## NuxtErrorBoundary
|
||||
|
||||
Catch and handle errors in child components:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtErrorBoundary @error="handleError">
|
||||
<ComponentThatMightFail />
|
||||
|
||||
<template #error="{ error, clearError }">
|
||||
<div class="error">
|
||||
<p>Something went wrong: {{ error.message }}</p>
|
||||
<button @click="clearError">Try again</button>
|
||||
</div>
|
||||
</template>
|
||||
</NuxtErrorBoundary>
|
||||
</template>
|
||||
|
||||
<script setup>
|
||||
function handleError(error) {
|
||||

```
|
||||
|

Render content only on client-side:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<ClientOnly>
|
||||
<!-- Browser-only component -->
|
||||
<BrowserOnlyChart :data="chartData" />
|
||||
|
||||
<template #fallback>
|
||||
<p>Loading chart...</p>
|
||||
</template>
|
||||
</ClientOnly>
|
||||
</template>
|
||||
```
|
||||
|
||||
## DevOnly
|
||||
|
||||
Render content only in development:
|
||||
|

## NuxtIsland
|
||||
|
||||
Server components (experimental):
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<NuxtIsland name="HeavyComponent" :props="{ data: complexData }" />
|
||||
</template>
|
||||
```
|
||||
|
||||
## NuxtImg and NuxtPicture
|
||||
|
||||
Optimized images (requires `@nuxt/image` module):
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<!-- Basic optimized image -->
|
||||
<NuxtImg src="/images/hero.jpg" width="800" height="600" />
|
||||
|
||||
<!-- Responsive with srcset -->
|
||||
<NuxtImg
|
||||
src="/images/hero.jpg"
|
||||
sizes="sm:100vw md:50vw lg:400px"
|
||||
:modifiers="{ format: 'webp' }"
|
||||
/>
|
||||
|
||||
<!-- Art direction with picture -->
|
||||
<NuxtPicture
|
||||
src="/images/hero.jpg"
|
||||
:img-attrs="{ alt: 'Hero image' }"
|
||||
/>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Teleport
|
||||
|
||||
Render content outside component tree:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<button @click="showModal = true">Open Modal</button>
|
||||
|

<div v-if="showModal" class="modal">
|
||||
<p>Modal content</p>
|
||||
<button @click="showModal = false">Close</button>
|
||||
</div>
|
||||
</Teleport>
|
||||
</template>
|
||||
```
|
||||
|
||||
For SSR, use `<ClientOnly>` with Teleport:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<ClientOnly>
|
||||
<Teleport to="#teleports">
|
||||
<Modal />

||||
```
|
||||
|
||||
## NuxtRouteAnnouncer

<NuxtRouteAnnouncer />
|
||||
<NuxtLayout>
|
||||
<NuxtPage />
|
||||
</NuxtLayout>
|
||||
</template>
|
||||
```

# Composables Auto-imports
|
||||
|
||||
Nuxt automatically imports Vue APIs, Nuxt composables, and your custom composables/utilities.
|
||||
|
||||
## Built-in Auto-imports
|
||||
|
||||
### Vue APIs
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// No imports needed - all auto-imported
|
||||
const count = ref(0)
|
||||
const doubled = computed(() => count.value * 2)
|
||||
|
||||
watch(count, (newVal) => {
|
||||
console.log('Count changed:', newVal)
|
||||
})
|
||||
|
||||
onMounted(() => {
|
||||
console.log('Component mounted')
|
||||
})
|
||||
|
||||
// Lifecycle hooks
|
||||
onBeforeMount(() => {})
|
||||
onUnmounted(() => {})
|
||||
onBeforeUnmount(() => {})
|
||||
|
||||
// Reactivity
|
||||
const state = reactive({ name: 'John' })
|
||||
const shallow = shallowRef({ deep: 'object' })
|
||||
</script>
|
||||
```
|
||||
|
||||
### Nuxt Composables
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// All auto-imported
|
||||
const route = useRoute()
|
||||
const router = useRouter()
|
||||
const config = useRuntimeConfig()
|
||||
const appConfig = useAppConfig()
|
||||
const nuxtApp = useNuxtApp()
|
||||
|
||||
// Data fetching
|
||||
const { data } = await useFetch('/api/data')
|
||||
const { data: asyncData } = await useAsyncData('key', () => fetchData())
|
||||
|
||||
// State
|
||||
const state = useState('key', () => 'initial')
|
||||
const cookie = useCookie('token')
|
||||
|
||||
// Head/SEO
|
||||
useHead({ title: 'My Page' })
|
||||
useSeoMeta({ description: 'Page description' })
|
||||
|
||||
// Request helpers (SSR)
|
||||
const headers = useRequestHeaders()
|
||||
const event = useRequestEvent()
|
||||
const url = useRequestURL()
|
||||
</script>
|
||||
```
|
||||
|
||||
## Custom Composables (`app/composables/`)
|
||||
|
||||
### Creating Composables
|
||||
|
||||
```ts
|
||||
// composables/useCounter.ts
|
||||
export function useCounter(initial = 0) {
|
||||
const count = ref(initial)
|
||||
const increment = () => count.value++
|
||||
const decrement = () => count.value--
|
||||
return { count, increment, decrement }
|
||||
}
|
||||
```
|
||||
|
||||
```ts
|
||||
// composables/useAuth.ts
|
||||
export function useAuth() {
|
||||
const user = useState<User | null>('user', () => null)
|
||||
const isLoggedIn = computed(() => !!user.value)
|
||||
|
||||
async function login(credentials: Credentials) {
|
||||
user.value = await $fetch('/api/auth/login', {
|
||||
method: 'POST',
|
||||
body: credentials,
|
||||
})
|
||||
}
|
||||
|
||||
async function logout() {
|
||||
await $fetch('/api/auth/logout', { method: 'POST' })
|
||||
user.value = null
|
||||
}
|
||||
|
||||
return { user, isLoggedIn, login, logout }
|
||||
}
|
||||
```
|
||||
|
||||
### Using Composables
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Auto-imported - no import statement needed
|
||||
const { count, increment } = useCounter(10)
|
||||
const { user, isLoggedIn, login } = useAuth()
|
||||
</script>
|
||||
```
|
||||
|
||||
### File Scanning Rules
|
||||
|
||||
Only top-level files are scanned:
|
||||
|
||||
```
|
||||
composables/
|
||||
├── useAuth.ts → useAuth() ✓
|
||||
├── useCounter.ts → useCounter() ✓
|
||||
├── index.ts → exports ✓
|
||||
└── nested/
|
||||
└── helper.ts → NOT auto-imported ✗
|
||||
```
|
||||
|
||||
Re-export nested composables:
|
||||
|
||||
```ts
|
||||
// composables/index.ts
|
||||
export { useHelper } from './nested/helper'
|
||||
```
|
||||
|
||||
Or configure scanning:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
imports: {
|
||||
dirs: [
|
||||
'composables',
|
||||
'composables/**', // Scan all nested
|
||||
],
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Utilities (`app/utils/`)
|
||||
|
||||
```ts
|
||||
// utils/format.ts
|
||||
export function formatDate(date: Date) {
|
||||
return date.toLocaleDateString()
|
||||
}
|
||||
|
||||
export function formatCurrency(amount: number) {
|
||||
return new Intl.NumberFormat('en-US', {
|
||||
style: 'currency',
|
||||
currency: 'USD',
|
||||
}).format(amount)
|
||||
}
|
||||
```
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Auto-imported
|
||||
const date = formatDate(new Date())
|
||||
const price = formatCurrency(99.99)
|
||||
</script>
|
||||
```
|
||||
|
||||
## Server Utils (`server/utils/`)
|
||||
|
||||
```ts
|
||||
// server/utils/db.ts
|
||||
export function useDb() {
|
||||
return createDbConnection()
|
||||
}
|
||||
|
||||
// server/utils/auth.ts
|
||||
export function verifyToken(token: string) {
|
||||
return jwt.verify(token, process.env.JWT_SECRET)
|
||||
}
|
||||
```
|
||||
|
||||
```ts
|
||||
// server/api/users.ts
|
||||
export default defineEventHandler(() => {
|
||||
const db = useDb() // Auto-imported
|
||||
return db.query('SELECT * FROM users')
|
||||
})
|
||||
```
|
||||
|
||||
## Third-party Package Imports
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
imports: {
|
||||
presets: [
|
||||
{
|
||||
from: 'vue-i18n',
|
||||
imports: ['useI18n'],
|
||||
},
|
||||
{
|
||||
from: 'date-fns',
|
||||
imports: ['format', 'parseISO', 'differenceInDays'],
|
||||
},
|
||||
{
|
||||
from: '@vueuse/core',
|
||||
imports: ['useMouse', 'useWindowSize'],
|
||||
},
|
||||
],
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
## Explicit Imports
|
||||
|
||||
Use `#imports` alias when needed:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
import { ref, computed, useFetch } from '#imports'
|
||||
</script>
|
||||
```
|
||||
|
||||
## Composable Context Rules
|
||||
|
||||
Nuxt composables must be called in valid context:
|
||||
|
||||
```ts
|
||||
// ❌ Wrong - module level
|
||||
const config = useRuntimeConfig()
|
||||
|
||||
export function useMyComposable() {}
|
||||
```
|
||||
|
||||
```ts
|
||||
// ✅ Correct - inside function
|
||||
export function useMyComposable() {
|
||||
const config = useRuntimeConfig()
|
||||
return { apiBase: config.public.apiBase }
|
||||
}
|
||||
```
|
||||
|
||||
**Valid contexts:**
|
||||
- `<script setup>` block
|
||||
- `setup()` function
|
||||
- `defineNuxtPlugin()` callback
|
||||
- `defineNuxtRouteMiddleware()` callback
|
||||
|
||||
## Disabling Auto-imports
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
// Disable all auto-imports
|
||||
imports: {
|
||||
autoImport: false,
|
||||
},
|
||||
|
||||
// Or disable only directory scanning (keep Vue/Nuxt imports)
|
||||
imports: {
|
||||
scan: false,
|
||||
},
|
||||
})
|
||||
```

# Server Routes
|
||||
|
||||
Nuxt includes Nitro server engine for building full-stack applications with API routes and server middleware.
|
||||
|
||||
## API Routes
|
||||
|
||||
Create files in `server/api/` directory:
|
||||
|
||||
```ts
|
||||
// server/api/hello.ts
|
||||
export default defineEventHandler((event) => {
|
||||
return { message: 'Hello World' }
|
||||
})
|
||||
```
|
||||
|
||||
Access at `/api/hello`.
|
||||
|
||||
### HTTP Methods
|
||||
|
||||
```ts
|
||||
// server/api/users.get.ts - GET /api/users
|
||||
export default defineEventHandler(() => {
|
||||
return getUsers()
|
||||
})
|
||||
|
||||
// server/api/users.post.ts - POST /api/users
|
||||
export default defineEventHandler(async (event) => {
|
||||
const body = await readBody(event)
|
||||
return createUser(body)
|
||||
})
|
||||
|
||||
// server/api/users/[id].put.ts - PUT /api/users/:id
|
||||
export default defineEventHandler(async (event) => {
|
||||
const id = getRouterParam(event, 'id')
|
||||
const body = await readBody(event)
|
||||
return updateUser(id, body)
|
||||
})
|
||||
|
||||
// server/api/users/[id].delete.ts - DELETE /api/users/:id
|
||||
export default defineEventHandler((event) => {
|
||||
const id = getRouterParam(event, 'id')
|
||||
return deleteUser(id)
|
||||
})
|
||||
```
|
||||
|
||||
### Route Parameters
|
||||
|
||||
```ts
|
||||
// server/api/posts/[id].ts
|
||||
export default defineEventHandler((event) => {
|
||||
const id = getRouterParam(event, 'id')
|
||||
return getPost(id)
|
||||
})
|
||||
|
||||
// Catch-all: server/api/[...path].ts
|
||||
export default defineEventHandler((event) => {
|
||||
const path = getRouterParam(event, 'path')
|
||||
return { path }
|
||||
})
|
||||
```
|
||||
|
||||
### Query Parameters
|
||||
|
||||
```ts
|
||||
// server/api/search.ts
|
||||
// GET /api/search?q=nuxt&page=1
|
||||
export default defineEventHandler((event) => {
|
||||
const query = getQuery(event)
|
||||
// { q: 'nuxt', page: '1' }
|
||||
return search(query.q, Number(query.page))
|
||||
})
|
||||
```
|
||||
|
||||
### Request Body
|
||||
|
||||
```ts
|
||||
// server/api/submit.post.ts
|
||||
export default defineEventHandler(async (event) => {
|
||||
const body = await readBody(event)
|
||||
// Validate and process body
|
||||
return { success: true, data: body }
|
||||
})
|
||||
```
|
||||
|
||||
### Headers and Cookies
|
||||
|
||||
```ts
|
||||
// server/api/auth.ts
|
||||
export default defineEventHandler((event) => {
|
||||
// Read headers
|
||||
const auth = getHeader(event, 'authorization')
|
||||
|
||||
// Read cookies
|
||||
const cookies = parseCookies(event)
|
||||
const token = getCookie(event, 'token')
|
||||
|
||||
// Set headers
|
||||
setHeader(event, 'X-Custom-Header', 'value')
|
||||
|
||||
// Set cookies
|
||||
setCookie(event, 'token', 'new-token', {
|
||||
httpOnly: true,
|
||||
secure: true,
|
||||
maxAge: 60 * 60 * 24, // 1 day
|
||||
})
|
||||
|
||||
return { authenticated: !!token }
|
||||
})
|
||||
```
|
||||
|
||||
## Server Middleware
|
||||
|
||||
Runs on every request before routes:
|
||||
|
||||
```ts
|
||||
// server/middleware/auth.ts
|
||||
export default defineEventHandler((event) => {
|
||||
const token = getCookie(event, 'token')
|
||||
|
||||
// Attach data to event context
|
||||
event.context.user = token ? verifyToken(token) : null
|
||||
})
|
||||
|
||||
// server/middleware/log.ts
|
||||
export default defineEventHandler((event) => {
|
||||
console.log(`${event.method} ${event.path}`)
|
||||
})
|
||||
```
|
||||
|
||||
Access context in routes:
|
||||
|
||||
```ts
|
||||
// server/api/profile.ts
|
||||
export default defineEventHandler((event) => {
|
||||
const user = event.context.user
|
||||
if (!user) {
|
||||
throw createError({ statusCode: 401, message: 'Unauthorized' })
|
||||
}
|
||||
return user
|
||||
})
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
```ts
|
||||
// server/api/users/[id].ts
|
||||
export default defineEventHandler((event) => {
|
||||
const id = getRouterParam(event, 'id')
|
||||
const user = findUser(id)
|
||||
|
||||
if (!user) {
|
||||
throw createError({
|
||||
statusCode: 404,
|
||||
statusMessage: 'User not found',
|
||||
})
|
||||
}
|
||||
|
||||
return user
|
||||
})
|
||||
```
|
||||
|
||||
## Server Utils
|
||||
|
||||
Auto-imported in `server/utils/`:
|
||||
|
||||
```ts
|
||||
// server/utils/db.ts
|
||||
export function useDb() {
|
||||
return createDbConnection()
|
||||
}
|
||||
```
|
||||
|
||||
```ts
|
||||
// server/api/users.ts
|
||||
export default defineEventHandler(() => {
|
||||
const db = useDb() // Auto-imported
|
||||
return db.query('SELECT * FROM users')
|
||||
})
|
||||
```
|
||||
|
||||
## Server Plugins
|
||||
|
||||
Run once when server starts:
|
||||
|
||||
```ts
|
||||
// server/plugins/db.ts
|
||||
export default defineNitroPlugin((nitroApp) => {
|
||||
// Initialize database connection
|
||||
const db = createDbConnection()
|
||||
|
||||
// Add to context
|
||||
nitroApp.hooks.hook('request', (event) => {
|
||||
event.context.db = db
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## Streaming Responses
|
||||
|
||||
```ts
|
||||
// server/api/stream.ts
|
||||
export default defineEventHandler((event) => {
|
||||
setHeader(event, 'Content-Type', 'text/event-stream')
|
||||
setHeader(event, 'Cache-Control', 'no-cache')
|
||||
setHeader(event, 'Connection', 'keep-alive')
|
||||
|
||||
const stream = new ReadableStream({
|
||||
async start(controller) {
|
||||
for (let i = 0; i < 10; i++) {
|
||||
controller.enqueue(`data: ${JSON.stringify({ count: i })}\n\n`)
|
||||
await new Promise(r => setTimeout(r, 1000))
|
||||
}
|
||||
controller.close()
|
||||
},
|
||||
})
|
||||
|
||||
return stream
|
||||
})
|
||||
```
|
||||
|
||||
## Server Storage
|
||||
|
||||
Key-value storage with multiple drivers:
|
||||
|
||||
```ts
|
||||
// server/api/cache.ts
|
||||
export default defineEventHandler(async (event) => {
|
||||
const storage = useStorage()
|
||||
|
||||
// Set value
|
||||
await storage.setItem('key', { data: 'value' })
|
||||
|
||||
// Get value
|
||||
const data = await storage.getItem('key')
|
||||
|
||||
return data
|
||||
})
|
||||
```
|
||||
|
||||
Configure storage drivers in `nuxt.config.ts`:
|
||||
|
||||
```ts
|
||||
export default defineNuxtConfig({
|
||||
nitro: {
|
||||
storage: {
|
||||
redis: {
|
||||
driver: 'redis',
|
||||
url: 'redis://localhost:6379',
|
||||
},
|
||||
},
|
||||
},
|
||||
})
|
||||
```

|
||||
|
||||
# State Management
|
||||
|
||||
Nuxt provides `useState` for SSR-friendly reactive state that persists across components.
|
||||
|
||||
## useState
|
||||
|
||||
SSR-safe replacement for `ref` that shares state across components:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// State is shared by key 'counter' across all components
|
||||
const counter = useState('counter', () => 0)
|
||||
</script>
|
||||
|
||||
<template>
|
||||
<div>
|
||||
Counter: {{ counter }}
|
||||
<button @click="counter++">+</button>
|
||||
<button @click="counter--">-</button>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Creating Shared State
|
||||
|
||||
Define reusable state composables:
|
||||
|
||||
```ts
|
||||
// composables/useUser.ts
|
||||
export function useUser() {
|
||||
return useState<User | null>('user', () => null)
|
||||
}
|
||||
|
||||
export function useLocale() {
|
||||
return useState('locale', () => 'en')
|
||||
}
|
||||
```
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
// Same state instance everywhere
|
||||
const user = useUser()
|
||||
const locale = useLocale()
|
||||
</script>
|
||||
```
|
||||
|
||||
## Initializing State
|
||||
|
||||
Use `callOnce` to initialize state with async data:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const config = useState('site-config')
|
||||
|
||||
await callOnce(async () => {
|
||||
config.value = await $fetch('/api/config')
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### ❌ Don't Define State Outside Setup
|
||||
|
||||
```ts
|
||||
// ❌ Wrong - causes memory leaks and shared state across requests
|
||||
export const globalState = ref({ user: null })
|
||||
```
|
||||
|
||||
### ✅ Use useState Instead
|
||||
|
||||
```ts
|
||||
// ✅ Correct - SSR-safe
|
||||
export const useGlobalState = () => useState('global', () => ({ user: null }))
|
||||
```
|
||||
|
||||
## Clearing State
|
||||
|
||||
```ts
|
||||
// Clear specific state
|
||||
clearNuxtState('counter')
|
||||
|
||||
// Clear multiple states
|
||||
clearNuxtState(['counter', 'user'])
|
||||
|
||||
// Clear all state (use with caution)
|
||||
clearNuxtState()
|
||||
```
|
||||
|
||||
## With Pinia
|
||||
|
||||
For complex state management, use Pinia:
|
||||
|
||||
```bash
|
||||
npx nuxi module add pinia
|
||||
```
|
||||
|
||||
```ts
|
||||
// stores/counter.ts
|
||||
export const useCounterStore = defineStore('counter', {
|
||||
state: () => ({
|
||||
count: 0,
|
||||
}),
|
||||
actions: {
|
||||
increment() {
|
||||
this.count++
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
```ts
|
||||
// stores/user.ts (Composition API style)
|
||||
export const useUserStore = defineStore('user', () => {
|
||||
const user = ref<User | null>(null)
|
||||
const isLoggedIn = computed(() => !!user.value)
|
||||
|
||||
async function login(credentials: Credentials) {
|
||||
user.value = await $fetch('/api/login', {
|
||||
method: 'POST',
|
||||
body: credentials,
|
||||
})
|
||||
}
|
||||
|
||||
return { user, isLoggedIn, login }
|
||||
})
|
||||
```
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
const counterStore = useCounterStore()
|
||||
const userStore = useUserStore()
|
||||
|
||||
// Initialize store data once
|
||||
await callOnce(async () => {
|
||||
await userStore.fetchUser()
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Advanced: Locale Example
|
||||
|
||||
```ts
|
||||
// composables/useLocale.ts
|
||||
export function useLocale() {
|
||||
return useState('locale', () => useDefaultLocale().value)
|
||||
}
|
||||
|
||||
export function useDefaultLocale(fallback = 'en-US') {
|
||||
const locale = ref(fallback)
|
||||
|
||||
if (import.meta.server) {
|
||||
const reqLocale = useRequestHeaders()['accept-language']?.split(',')[0]
|
||||
if (reqLocale) locale.value = reqLocale
|
||||
}
|
||||
else if (import.meta.client) {
|
||||
const navLang = navigator.language
|
||||
if (navLang) locale.value = navLang
|
||||
}
|
||||
|
||||
return locale
|
||||
}
|
||||
```
|
||||
|
||||
## State Serialization
|
||||
|
||||
`useState` values are serialized to JSON. Avoid:
|
||||
|
||||
- Functions
|
||||
- Classes
|
||||
- Symbols
|
||||
- Circular references
|
||||
|
||||
```ts
|
||||
// ❌ Won't work
|
||||
useState('fn', () => () => console.log('hi'))
|
||||
useState('instance', () => new MyClass())
|
||||
|
||||
// ✅ Works
|
||||
useState('data', () => ({ name: 'John', age: 30 }))
|
||||
useState('items', () => ['a', 'b', 'c'])
|
||||
```
|

# Rendering Modes
|
||||
|
||||
Nuxt supports multiple rendering modes: universal (SSR), client-side (CSR), and hybrid rendering.
|
||||
|
||||
## Universal Rendering (Default)
|
||||
|
||||
Server renders HTML, then hydrates on client:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts - this is the default
|
||||
export default defineNuxtConfig({
|
||||
ssr: true,
|
||||
})
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Fast initial page load (HTML is ready)
|
||||
- SEO-friendly (content is in HTML)
|
||||
- Works without JavaScript initially
|
||||
|
||||
**How it works:**
|
||||
1. Server executes Vue code, generates HTML
|
||||
2. Browser displays HTML immediately
|
||||
3. JavaScript loads and hydrates the page
|
||||
4. Page becomes fully interactive
|
||||
|
||||
## Client-Side Rendering
|
||||
|
||||
Render entirely in the browser:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
ssr: false,
|
||||
})
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Simpler development (no SSR constraints)
|
||||
- Cheaper hosting (static files only)
|
||||
- Works offline
|
||||
|
||||
**Use cases:**
|
||||
- Admin dashboards
|
||||
- SaaS applications
|
||||
- Apps behind authentication
|
||||
|
||||
### SPA Loading Template
|
||||
|
||||
Provide loading UI while app hydrates:
|
||||
|
||||
```html
|
||||
<!-- app/spa-loading-template.html -->
|
||||
<div class="loading">
|
||||
<div class="spinner"></div>
|
||||
<p>Loading...</p>
|
||||
</div>
|
||||
|
||||
<style>
|
||||
.loading {
|
||||
display: flex;
|
||||
flex-direction: column;
|
||||
align-items: center;
|
||||
justify-content: center;
|
||||
height: 100vh;
|
||||
}
|
||||
.spinner {
|
||||
width: 40px;
|
||||
height: 40px;
|
||||
border: 4px solid #f3f3f3;
|
||||
border-top: 4px solid #00dc82;
|
||||
border-radius: 50%;
|
||||
animation: spin 1s linear infinite;
|
||||
}
|
||||
@keyframes spin {
|
||||
to { transform: rotate(360deg); }
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
## Hybrid Rendering
|
||||
|
||||
Mix rendering modes per route using route rules:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
routeRules: {
|
||||
// Static pages - prerendered at build
|
||||
'/': { prerender: true },
|
||||
'/about': { prerender: true },
|
||||
|
||||
// ISR - regenerate in background
|
||||
'/blog/**': { isr: 3600 }, // Cache for 1 hour
|
||||
'/products/**': { swr: true }, // Stale-while-revalidate
|
||||
|
||||
// Client-only rendering
|
||||
'/admin/**': { ssr: false },
|
||||
'/dashboard/**': { ssr: false },
|
||||
|
||||
// Server-rendered (default)
|
||||
'/api/**': { cors: true },
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Route Rules Reference
|
||||
|
||||
| Rule | Description |
|
||||
|------|-------------|
|
||||
| `prerender: true` | Pre-render at build time |
|
||||
| `ssr: false` | Client-side only |
|
||||
| `swr: number \| true` | Stale-while-revalidate caching |
|
||||
| `isr: number \| true` | Incremental static regeneration |
|
||||
| `cache: { maxAge: number }` | Cache with TTL |
|
||||
| `redirect: string` | Redirect to another path |
|
||||
| `cors: true` | Add CORS headers |
|
||||
| `headers: object` | Custom response headers |
|
||||
|
||||
### Inline Route Rules
|
||||
|
||||
Define per-page:
|
||||
|
||||
```vue
|
||||
<script setup lang="ts">
|
||||
defineRouteRules({
|
||||
prerender: true,
|
||||
})
|
||||
</script>
|
||||
```
|
||||
|
||||
## Prerendering
|
||||
|
||||
Generate static HTML at build time:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
// Prerender specific routes
|
||||
routeRules: {
|
||||
'/': { prerender: true },
|
||||
'/about': { prerender: true },
|
||||
'/posts/*': { prerender: true },
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Or use `nuxt generate`:
|
||||
|
||||
```bash
|
||||
nuxt generate
|
||||
```
|
||||
|
||||
### Programmatic Prerendering
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
hooks: {
|
||||
'prerender:routes'({ routes }) {
|
||||
// Add dynamic routes
|
||||
const posts = await fetchPostSlugs()
|
||||
for (const slug of posts) {
|
||||
routes.add(`/posts/${slug}`)
|
||||
}
|
||||
},
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Or in pages:
|
||||
|
||||
```ts
|
||||
// server/api/posts.ts or a plugin
|
||||
prerenderRoutes(['/posts/1', '/posts/2', '/posts/3'])
|
||||
```
|
||||
|
||||
## Edge-Side Rendering
|
||||
|
||||
Render at CDN edge servers:
|
||||
|
||||
```ts
|
||||
// nuxt.config.ts
|
||||
export default defineNuxtConfig({
|
||||
nitro: {
|
||||
preset: 'cloudflare-pages', // or 'vercel-edge', 'netlify-edge'
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
Supported platforms:
|
||||
- Cloudflare Pages/Workers
|
||||
- Vercel Edge Functions
|
||||
- Netlify Edge Functions
|
||||
|
||||
## Conditional Rendering
|
||||
|
||||
Use `import.meta.server` and `import.meta.client`:
|
||||
|
||||
```vue
|
||||
<script setup>
|
||||
if (import.meta.server) {
|
||||
// Server-only code
|
||||
console.log('Running on server')
|
||||
}
|
||||
|
||||
if (import.meta.client) {
|
||||
// Client-only code
|
||||
console.log('Running in browser')
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
For components:
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<ClientOnly>
|
||||
<BrowserOnlyComponent />
|
||||
<template #fallback>
|
||||
<p>Loading...</p>
|
||||
</template>
|
||||
</ClientOnly>
|
||||
</template>
|
||||
```

# Test Generation with Playwright MCP
|
||||
|
||||
Your goal is to generate a Playwright test based on the provided scenario after completing all prescribed steps.
|
||||
|
||||
## Specific Instructions
|
||||
|
||||
- You are given a scenario, and you need to generate a playwright test for it. If the user does not provide a scenario, you will ask them to provide one.
|
||||
- DO NOT generate test code prematurely or based solely on the scenario without completing all prescribed steps.
|
||||
- DO run steps one by one using the tools provided by the Playwright MCP.
|
||||
- Only after all steps are completed, emit a Playwright TypeScript test that uses `@playwright/test` based on message history
|
||||
- Save generated test file in the tests directory
|
||||
- Execute the test file and iterate until the test passes

pnpm is a fast, disk space efficient package manager. It uses a content-addressable store to deduplicate packages across all projects on a machine, saving significant disk space. pnpm enforces strict dependency resolution by default, preventing phantom dependencies. Configuration should preferably be placed in `pnpm-workspace.yaml` for pnpm-specific settings.
|
||||
|
||||
**Important:** When working with pnpm projects, agents should check for `pnpm-workspace.yaml` and `.npmrc` files to understand workspace structure and configuration. Always use `--frozen-lockfile` in CI environments.

# pnpm CI/CD Setup
|
||||
|
||||
Best practices for using pnpm in CI/CD environments for fast, reliable builds.
|
||||
|
||||
## GitHub Actions
|
||||
|
||||
### Basic Setup
|
||||
|
||||
```yaml
|
||||
name: CI
|
||||
|
||||
on: [push, pull_request]
|
||||
|
||||
jobs:
|
||||
build:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
|
||||
- uses: pnpm/action-setup@v4
|
||||
with:
|
||||
version: 9
|
||||
|
||||
- uses: actions/setup-node@v4
|
||||
with:
|
||||
node-version: 20
|
||||
cache: 'pnpm'
|
||||
|
||||
- run: pnpm install --frozen-lockfile
|
||||
- run: pnpm test
|
||||
- run: pnpm build
|
||||
```
|
||||
|
||||
### With Store Caching
|
||||
|
||||
For larger projects, cache the pnpm store:
|
||||
|
||||
```yaml
|
||||
- uses: pnpm/action-setup@v4
|
||||
with:
|
||||
version: 9
|
||||
|
||||
- name: Get pnpm store directory
|
||||
shell: bash
|
||||
run: |
|
||||
echo "STORE_PATH=$(pnpm store path --silent)" >> $GITHUB_ENV
|
||||
|
||||
- uses: actions/cache@v4
|
||||
name: Setup pnpm cache
|
||||
with:
|
||||
path: ${{ env.STORE_PATH }}
|
||||
key: ${{ runner.os }}-pnpm-store-${{ hashFiles('**/pnpm-lock.yaml') }}
|
||||
restore-keys: |
|
||||
${{ runner.os }}-pnpm-store-
|
||||
|
||||
- run: pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
### Matrix Testing
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
test:
|
||||
runs-on: ${{ matrix.os }}
|
||||
strategy:
|
||||
matrix:
|
||||
os: [ubuntu-latest, windows-latest, macos-latest]
|
||||
node: [18, 20, 22]
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
- uses: pnpm/action-setup@v4
|
||||
- uses: actions/setup-node@v4
|
||||
with:
|
||||
node-version: ${{ matrix.node }}
|
||||
cache: 'pnpm'
|
||||
- run: pnpm install --frozen-lockfile
|
||||
- run: pnpm test
|
||||
```
|
||||
|
||||
## GitLab CI
|
||||
|
||||
```yaml
|
||||
image: node:20
|
||||
|
||||
stages:
|
||||
- install
|
||||
- test
|
||||
- build
|
||||
|
||||
variables:
|
||||
PNPM_HOME: /root/.local/share/pnpm
|
||||
PATH: $PNPM_HOME:$PATH
|
||||
|
||||
before_script:
|
||||
- corepack enable
|
||||
- corepack prepare pnpm@latest --activate
|
||||
|
||||
cache:
|
||||
key: ${CI_COMMIT_REF_SLUG}
|
||||
paths:
|
||||
- .pnpm-store
|
||||
|
||||
install:
|
||||
stage: install
|
||||
script:
|
||||
- pnpm config set store-dir .pnpm-store
|
||||
- pnpm install --frozen-lockfile
|
||||
|
||||
test:
|
||||
stage: test
|
||||
script:
|
||||
- pnpm test
|
||||
|
||||
build:
|
||||
stage: build
|
||||
script:
|
||||
- pnpm build
|
||||
```
|
||||
|
||||
## Docker
|
||||
|
||||
### Multi-Stage Build
|
||||
|
||||
```dockerfile
|
||||
# Build stage
|
||||
FROM node:20-slim AS builder
|
||||
|
||||
# Enable corepack for pnpm
|
||||
RUN corepack enable
|
||||
|
||||
WORKDIR /app
|
||||
|
||||
# Copy package files first for layer caching
|
||||
COPY package.json pnpm-lock.yaml pnpm-workspace.yaml ./
|
||||
COPY packages/*/package.json ./packages/
|
||||
|
||||
# Install dependencies
|
||||
RUN pnpm install --frozen-lockfile
|
||||
|
||||
# Copy source and build
|
||||
COPY . .
|
||||
RUN pnpm build
|
||||
|
||||
# Production stage
|
||||
FROM node:20-slim AS runner
|
||||
|
||||
RUN corepack enable
|
||||
WORKDIR /app
|
||||
|
||||
COPY --from=builder /app/dist ./dist
|
||||
COPY --from=builder /app/package.json ./
|
||||
COPY --from=builder /app/pnpm-lock.yaml ./
|
||||
|
||||
# Production install
|
||||
RUN pnpm install --frozen-lockfile --prod
|
||||
|
||||
CMD ["node", "dist/index.js"]
|
||||
```
|
||||
|
||||
### Optimized for Monorepos
|
||||
|
||||
```dockerfile
|
||||
FROM node:20-slim AS builder
|
||||
RUN corepack enable
|
||||
WORKDIR /app
|
||||
|
||||
# Copy workspace config
|
||||
COPY pnpm-lock.yaml pnpm-workspace.yaml ./
|
||||
|
||||
# Copy all package.json files maintaining structure
|
||||
COPY packages/core/package.json ./packages/core/
|
||||
COPY packages/api/package.json ./packages/api/
|
||||
|
||||
# Install all dependencies
|
||||
RUN pnpm install --frozen-lockfile
|
||||
|
||||
# Copy source
|
||||
COPY . .
|
||||
|
||||
# Build specific package
|
||||
RUN pnpm --filter @myorg/api build
|
||||
```
|
||||
|
||||
## Key CI Flags
|
||||
|
||||
### --frozen-lockfile
|
||||
|
||||
**Always use in CI.** Fails if `pnpm-lock.yaml` needs updates:
|
||||
|
||||
```bash
|
||||
pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
### --prefer-offline
|
||||
|
||||
Use cached packages when available:
|
||||
|
||||
```bash
|
||||
pnpm install --frozen-lockfile --prefer-offline
|
||||
```
|
||||
|
||||
### --ignore-scripts
|
||||
|
||||
Skip lifecycle scripts for faster installs (use cautiously):
|
||||
|
||||
```bash
|
||||
pnpm install --frozen-lockfile --ignore-scripts
|
||||
```
|
||||
|
||||
## Corepack Integration
|
||||
|
||||
Use Corepack to manage pnpm version:
|
||||
|
||||
```json
|
||||
// package.json
|
||||
{
|
||||
"packageManager": "pnpm@9.0.0"
|
||||
}
|
||||
```
|
||||
|
||||
```yaml
|
||||
# GitHub Actions
|
||||
- run: corepack enable
|
||||
- run: pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
## Monorepo CI Strategies
|
||||
|
||||
### Build Changed Packages Only
|
||||
|
||||
```yaml
|
||||
- name: Build changed packages
|
||||
run: |
|
||||
pnpm --filter "...[origin/main]" build
|
||||
```
|
||||
|
||||
### Parallel Jobs per Package
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
detect-changes:
|
||||
runs-on: ubuntu-latest
|
||||
outputs:
|
||||
packages: ${{ steps.changes.outputs.packages }}
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
with:
|
||||
fetch-depth: 0
|
||||
- id: changes
|
||||
run: |
|
||||
echo "packages=$(pnpm --filter '...[origin/main]' list --json | jq -c '[.[].name]')" >> $GITHUB_OUTPUT
|
||||
|
||||
test:
|
||||
needs: detect-changes
|
||||
if: needs.detect-changes.outputs.packages != '[]'
|
||||
runs-on: ubuntu-latest
|
||||
strategy:
|
||||
matrix:
|
||||
package: ${{ fromJson(needs.detect-changes.outputs.packages) }}
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
- uses: pnpm/action-setup@v4
|
||||
- run: pnpm install --frozen-lockfile
|
||||
- run: pnpm --filter ${{ matrix.package }} test
|
||||
```
|
||||
|
||||
## Best Practices Summary
|
||||
|
||||
1. **Always use `--frozen-lockfile`** in CI
|
||||
2. **Cache the pnpm store** for faster installs
|
||||
3. **Use Corepack** for consistent pnpm versions
|
||||
4. **Specify `packageManager`** in package.json
|
||||
5. **Use `--filter`** in monorepos to build only what changed
|
||||
6. **Multi-stage Docker builds** for smaller images

# Migration to pnpm
|
||||
|
||||
Guide for migrating existing projects from npm or Yarn to pnpm.
|
||||
|
||||
## Quick Migration
|
||||
|
||||
### From npm
|
||||
|
||||
```bash
|
||||
# Remove npm lockfile and node_modules
|
||||
rm -rf node_modules package-lock.json
|
||||
|
||||
# Install with pnpm
|
||||
pnpm install
|
||||
```
|
||||
|
||||
### From Yarn
|
||||
|
||||
```bash
|
||||
# Remove yarn lockfile and node_modules
|
||||
rm -rf node_modules yarn.lock
|
||||
|
||||
# Install with pnpm
|
||||
pnpm install
|
||||
```
|
||||
|
||||
### Import Existing Lockfile
|
||||
|
||||
pnpm can import existing lockfiles:
|
||||
|
||||
```bash
|
||||
# Import from npm or yarn lockfile
|
||||
pnpm import
|
||||
|
||||
# This creates pnpm-lock.yaml from:
|
||||
# - package-lock.json (npm)
|
||||
# - yarn.lock (yarn)
|
||||
# - npm-shrinkwrap.json (npm)
|
||||
```
|
||||
|
||||
## Handling Common Issues
|
||||
|
||||
### Phantom Dependencies
|
||||
|
||||
pnpm is strict about dependencies. If code imports a package not in `package.json`, it will fail.
|
||||
|
||||
**Problem:**
|
||||
```js
|
||||
// Works with npm (hoisted), fails with pnpm
|
||||
import lodash from 'lodash' // Not in dependencies, installed by another package
|
||||
```
|
||||
|
||||
**Solution:** Add missing dependencies explicitly:
|
||||
```bash
|
||||
pnpm add lodash
|
||||
```
|
||||
|
||||
### Missing Peer Dependencies
|
||||
|
||||
pnpm reports peer dependency issues by default.
|
||||
|
||||
**Option 1:** Let pnpm auto-install:
|
||||
```ini
|
||||
# .npmrc (default in pnpm v8+)
|
||||
auto-install-peers=true
|
||||
```
|
||||
|
||||
**Option 2:** Install manually:
|
||||
```bash
|
||||
pnpm add react react-dom
|
||||
```
|
||||
|
||||
**Option 3:** Suppress warnings if acceptable:
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"ignoreMissing": ["react"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Symlink Issues
|
||||
|
||||
Some tools don't work with symlinks. Use hoisted mode:
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
node-linker=hoisted
|
||||
```
|
||||
|
||||
Or hoist specific packages:
|
||||
|
||||
```ini
|
||||
public-hoist-pattern[]=*eslint*
|
||||
public-hoist-pattern[]=*babel*
|
||||
```
|
||||
|
||||
### Native Module Rebuilds
|
||||
|
||||
If native modules fail, try:
|
||||
|
||||
```bash
|
||||
# Rebuild all native modules
|
||||
pnpm rebuild
|
||||
|
||||
# Or reinstall
|
||||
rm -rf node_modules
|
||||
pnpm install
|
||||
```
|
||||
|
||||
## Monorepo Migration
|
||||
|
||||
### From npm Workspaces
|
||||
|
||||
1. Create `pnpm-workspace.yaml`:
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
```
|
||||
|
||||
2. Update internal dependencies to use workspace protocol:
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"@myorg/utils": "workspace:^"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3. Install:
|
||||
```bash
|
||||
rm -rf node_modules packages/*/node_modules package-lock.json
|
||||
pnpm install
|
||||
```
|
||||
|
||||
### From Yarn Workspaces
|
||||
|
||||
1. Remove Yarn-specific files:
|
||||
```bash
|
||||
rm yarn.lock .yarnrc.yml
|
||||
rm -rf .yarn
|
||||
```
|
||||
|
||||
2. Create `pnpm-workspace.yaml` matching `workspaces` in package.json:
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
```
|
||||
|
||||
3. Update `package.json` - remove Yarn workspace config if not needed:
|
||||
```json
|
||||
{
|
||||
// Remove "workspaces" field (optional, pnpm uses pnpm-workspace.yaml)
|
||||
}
|
||||
```
|
||||
|
||||
4. Convert workspace references:
|
||||
```json
|
||||
// From Yarn
|
||||
"@myorg/utils": "*"
|
||||
|
||||
// To pnpm
|
||||
"@myorg/utils": "workspace:*"
|
||||
```
|
||||
|
||||
### From Lerna
|
||||
|
||||
pnpm can replace Lerna for most use cases:
|
||||
|
||||
```bash
|
||||
# Lerna: run script in all packages
|
||||
lerna run build
|
||||
|
||||
# pnpm equivalent
|
||||
pnpm -r run build
|
||||
|
||||
# Lerna: run in specific package
|
||||
lerna run build --scope=@myorg/app
|
||||
|
||||
# pnpm equivalent
|
||||
pnpm --filter @myorg/app run build
|
||||
|
||||
# Lerna: publish
|
||||
lerna publish
|
||||
|
||||
# pnpm: use changesets instead
|
||||
pnpm add -Dw @changesets/cli
|
||||
pnpm changeset
|
||||
pnpm changeset version
|
||||
pnpm publish -r
|
||||
```
|
||||
|
||||
## Configuration Migration
|
||||
|
||||
### .npmrc Settings
|
||||
|
||||
Most npm/Yarn settings work in pnpm's `.npmrc`:
|
||||
|
||||
```ini
|
||||
# Registry settings (same as npm)
|
||||
registry=https://registry.npmjs.org/
|
||||
@myorg:registry=https://npm.myorg.com/
|
||||
|
||||
# Auth tokens (same as npm)
|
||||
//registry.npmjs.org/:_authToken=${NPM_TOKEN}
|
||||
|
||||
# pnpm-specific additions
|
||||
auto-install-peers=true
|
||||
strict-peer-dependencies=false
|
||||
```
|
||||
|
||||
### Scripts Migration
|
||||
|
||||
Most scripts work unchanged. Update pnpm-specific patterns:
|
||||
|
||||
```json
|
||||
{
|
||||
"scripts": {
|
||||
// npm: recursive scripts
|
||||
"build:all": "npm run build --workspaces",
|
||||
// pnpm: use -r flag
|
||||
"build:all": "pnpm -r run build",
|
||||
|
||||
// npm: run in specific workspace
|
||||
"dev:app": "npm run dev -w packages/app",
|
||||
// pnpm: use --filter
|
||||
"dev:app": "pnpm --filter @myorg/app run dev"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## CI/CD Migration
|
||||
|
||||
Update CI configuration:
|
||||
|
||||
```yaml
|
||||
# Before (npm)
|
||||
- run: npm ci
|
||||
|
||||
# After (pnpm)
|
||||
- uses: pnpm/action-setup@v4
|
||||
- run: pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
Add to `package.json` for Corepack:
|
||||
```json
|
||||
{
|
||||
"packageManager": "pnpm@9.0.0"
|
||||
}
|
||||
```
|
||||
|
||||
## Gradual Migration
|
||||
|
||||
For large projects, migrate gradually:
|
||||
|
||||
1. **Start with CI**: Use pnpm in CI, keep npm/yarn locally
|
||||
2. **Add pnpm-lock.yaml**: Run `pnpm import` to create lockfile
|
||||
3. **Test thoroughly**: Ensure builds work with pnpm
|
||||
4. **Update documentation**: Update README, CONTRIBUTING
|
||||
5. **Remove old files**: Delete old lockfiles after team adoption
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If migration causes issues:
|
||||
|
||||
```bash
|
||||
# Remove pnpm files
|
||||
rm -rf node_modules pnpm-lock.yaml pnpm-workspace.yaml
|
||||
|
||||
# Restore npm
|
||||
npm install
|
||||
|
||||
# Or restore Yarn
|
||||
yarn install
|
||||
```
|
||||
|
||||
Keep old lockfile in git history for easy rollback.

# pnpm Performance Optimization
|
||||
|
||||
pnpm is fast by default, but these optimizations can make it even faster.
|
||||
|
||||
## Install Optimizations
|
||||
|
||||
### Use Frozen Lockfile
|
||||
|
||||
Skip resolution when lockfile exists:
|
||||
|
||||
```bash
|
||||
pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
This is faster because pnpm skips the resolution phase entirely.
|
||||
|
||||
### Prefer Offline Mode
|
||||
|
||||
Use cached packages when available:
|
||||
|
||||
```bash
|
||||
pnpm install --prefer-offline
|
||||
```
|
||||
|
||||
Or configure globally:
|
||||
```ini
|
||||
# .npmrc
|
||||
prefer-offline=true
|
||||
```
|
||||
|
||||
### Skip Optional Dependencies
|
||||
|
||||
If you don't need optional deps:
|
||||
|
||||
```bash
|
||||
pnpm install --no-optional
|
||||
```
|
||||
|
||||
### Skip Scripts
|
||||
|
||||
For CI or when scripts aren't needed:
|
||||
|
||||
```bash
|
||||
pnpm install --ignore-scripts
|
||||
```
|
||||
|
||||
**Caution:** Some packages require postinstall scripts to work correctly.
|
||||
|
||||
### Only Build Specific Dependencies
|
||||
|
||||
Only run build scripts for specific packages:
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
onlyBuiltDependencies[]=esbuild
|
||||
onlyBuiltDependencies[]=sharp
|
||||
onlyBuiltDependencies[]=@swc/core
|
||||
```
|
||||
|
||||
Or skip builds entirely for deps that don't need them:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"neverBuiltDependencies": ["fsevents", "cpu-features"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Store Optimizations
|
||||
|
||||
### Side Effects Cache
|
||||
|
||||
Cache native module build results:
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
side-effects-cache=true
|
||||
```
|
||||
|
||||
This caches the results of postinstall scripts, speeding up subsequent installs.
|
||||
|
||||
### Shared Store
|
||||
|
||||
Use a single store for all projects (default behavior):
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
store-dir=~/.pnpm-store
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Packages downloaded once for all projects
|
||||
- Hard links save disk space
|
||||
- Faster installs from cache
|
||||
|
||||
### Store Maintenance
|
||||
|
||||
Periodically clean unused packages:
|
||||
|
||||
```bash
|
||||
# Remove unreferenced packages
|
||||
pnpm store prune
|
||||
|
||||
# Check store integrity
|
||||
pnpm store status
|
||||
```
|
||||
|
||||
## Workspace Optimizations
|
||||
|
||||
### Parallel Execution
|
||||
|
||||
Run workspace scripts in parallel:
|
||||
|
||||
```bash
|
||||
pnpm -r --parallel run build
|
||||
```
|
||||
|
||||
Control concurrency:
|
||||
```ini
|
||||
# .npmrc
|
||||
workspace-concurrency=8
|
||||
```
|
||||
|
||||
### Stream Output
|
||||
|
||||
See output in real-time:
|
||||
|
||||
```bash
|
||||
pnpm -r --stream run build
|
||||
```
|
||||
|
||||
### Filter to Changed Packages
|
||||
|
||||
Only build what changed:
|
||||
|
||||
```bash
|
||||
# Build packages changed since main branch
|
||||
pnpm --filter "...[origin/main]" run build
|
||||
```
|
||||
|
||||
### Topological Order
|
||||
|
||||
Build dependencies before dependents:
|
||||
|
||||
```bash
|
||||
pnpm -r run build
|
||||
# Automatically runs in topological order
|
||||
```
|
||||
|
||||
For explicit sequential builds:
|
||||
```bash
|
||||
pnpm -r --workspace-concurrency=1 run build
|
||||
```
|
||||
|
||||
## Network Optimizations
|
||||
|
||||
### Configure Registry
|
||||
|
||||
Use closest/fastest registry:
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
registry=https://registry.npmmirror.com/
|
||||
```
|
||||
|
||||
### HTTP Settings
|
||||
|
||||
Tune network settings:
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
fetch-retries=3
|
||||
fetch-retry-mintimeout=10000
|
||||
fetch-retry-maxtimeout=60000
|
||||
network-concurrency=16
|
||||
```
|
||||
|
||||
### Proxy Configuration
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
proxy=http://proxy.company.com:8080
|
||||
https-proxy=http://proxy.company.com:8080
|
||||
```
|
||||
|
||||
## Lockfile Optimization
|
||||
|
||||
### Single Lockfile (Monorepos)
|
||||
|
||||
Use shared lockfile for all packages (default):
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
shared-workspace-lockfile=true
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Single source of truth
|
||||
- Faster resolution
|
||||
- Consistent versions across workspace
|
||||
|
||||
### Lockfile-only Mode
|
||||
|
||||
Only update lockfile without installing:
|
||||
|
||||
```bash
|
||||
pnpm install --lockfile-only
|
||||
```
|
||||
|
||||
## Benchmarking
|
||||
|
||||
### Compare Install Times
|
||||
|
||||
```bash
|
||||
# Clean install
|
||||
rm -rf node_modules pnpm-lock.yaml
|
||||
time pnpm install
|
||||
|
||||
# Cached install (with lockfile)
|
||||
rm -rf node_modules
|
||||
time pnpm install --frozen-lockfile
|
||||
|
||||
# With store cache
|
||||
time pnpm install --frozen-lockfile --prefer-offline
|
||||
```
|
||||
|
||||
### Profile Resolution
|
||||
|
||||
Debug slow installs:
|
||||
|
||||
```bash
|
||||
# Verbose logging
|
||||
pnpm install --reporter=append-only
|
||||
|
||||
# Debug mode
|
||||
DEBUG=pnpm:* pnpm install
|
||||
```
|
||||
|
||||
## Configuration Summary
|
||||
|
||||
Optimized `.npmrc` for performance:
|
||||
|
||||
```ini
|
||||
# Install behavior
|
||||
prefer-offline=true
|
||||
auto-install-peers=true
|
||||
|
||||
# Build optimization
|
||||
side-effects-cache=true
|
||||
# Only build what's necessary
|
||||
onlyBuiltDependencies[]=esbuild
|
||||
onlyBuiltDependencies[]=@swc/core
|
||||
|
||||
# Network
|
||||
fetch-retries=3
|
||||
network-concurrency=16
|
||||
|
||||
# Workspace
|
||||
workspace-concurrency=4
|
||||
```
|
||||
|
||||

# pnpm CLI Commands
|
||||
|
||||
pnpm provides a comprehensive CLI for package management with commands similar to npm/yarn but with unique features.
|
||||
|
||||
## Installation Commands
|
||||
|
||||
### Install all dependencies
|
||||
```bash
|
||||
pnpm install
|
||||
# or
|
||||
pnpm i
|
||||
```
|
||||
|
||||
### Add a dependency
|
||||
```bash
|
||||
# Production dependency
|
||||
pnpm add <pkg>
|
||||
|
||||
# Dev dependency
|
||||
pnpm add -D <pkg>
|
||||
pnpm add --save-dev <pkg>
|
||||
|
||||
# Optional dependency
|
||||
pnpm add -O <pkg>
|
||||
|
||||
# Global package
|
||||
pnpm add -g <pkg>
|
||||
|
||||
# Specific version
|
||||
pnpm add <pkg>@<version>
|
||||
pnpm add <pkg>@next
|
||||
pnpm add <pkg>@^1.0.0
|
||||
```
|
||||
|
||||
### Remove a dependency
|
||||
```bash
|
||||
pnpm remove <pkg>
|
||||
pnpm rm <pkg>
|
||||
pnpm uninstall <pkg>
|
||||
pnpm un <pkg>
|
||||
```
|
||||
|
||||
### Update dependencies
|
||||
```bash
|
||||
# Update all
|
||||
pnpm update
|
||||
pnpm up
|
||||
|
||||
# Update specific package
|
||||
pnpm update <pkg>
|
||||
|
||||
# Update to latest (ignore semver)
|
||||
pnpm update --latest
|
||||
pnpm up -L
|
||||
|
||||
# Interactive update
|
||||
pnpm update --interactive
|
||||
pnpm up -i
|
||||
```
|
||||
|
||||
## Script Commands
|
||||
|
||||
### Run scripts
|
||||
```bash
|
||||
pnpm run <script>
|
||||
# or shorthand
|
||||
pnpm <script>
|
||||
|
||||
# Pass arguments to script
|
||||
pnpm run build -- --watch
|
||||
|
||||
# Run script if exists (no error if missing)
|
||||
pnpm run --if-present build
|
||||
```
|
||||
|
||||
### Execute binaries
|
||||
```bash
|
||||
# Run local binary
|
||||
pnpm exec <command>
|
||||
|
||||
# Example
|
||||
pnpm exec eslint .
|
||||
```
|
||||
|
||||
### dlx - Run without installing
|
||||
```bash
|
||||
# Like npx but for pnpm
|
||||
pnpm dlx <pkg>
|
||||
|
||||
# Examples
|
||||
pnpm dlx create-vite my-app
|
||||
pnpm dlx degit user/repo my-project
|
||||
```
|
||||
|
||||
## Workspace Commands
|
||||
|
||||
### Run in all packages
|
||||
```bash
|
||||
# Run script in all workspace packages
|
||||
pnpm -r run <script>
|
||||
pnpm --recursive run <script>
|
||||
|
||||
# Run in specific packages
|
||||
pnpm --filter <pattern> run <script>
|
||||
|
||||
# Examples
|
||||
pnpm --filter "./packages/**" run build
|
||||
pnpm --filter "!./packages/internal/**" run test
|
||||
pnpm --filter "@myorg/*" run lint
|
||||
```
|
||||
|
||||
### Filter patterns

||||
pnpm --filter <pkg-name> <command>
|
||||
pnpm --filter "@scope/pkg" build
|
||||
|
||||
# By directory
|
||||
pnpm --filter "./packages/core" test
|
||||
|
||||
# Dependencies of a package
|
||||
pnpm --filter "...@scope/app" build
|
||||
|
||||
# Dependents of a package
|
||||
pnpm --filter "@scope/core..." test
|
||||
|
||||
# Changed packages since commit/branch
|
||||
pnpm --filter "...[origin/main]" build
|
||||
```
|
||||
|
||||
## Other Useful Commands
|
||||
|
||||
### Link packages

||||
# Use linked package
|
||||
pnpm link --global <pkg>
|
||||
```
|
||||
|
||||
### Patch packages
|
||||
```bash
|
||||
# Create patch for a package
|
||||
pnpm patch <pkg>@<version>
|
||||
|
||||
# After editing, commit the patch
|
||||
pnpm patch-commit <path>
|
||||
|
||||
# Remove a patch
|
||||
pnpm patch-remove <pkg>
|
||||
```
|
||||
|
||||
### Store management

# pnpm Configuration
|
||||
|
||||
pnpm uses two main configuration files: `pnpm-workspace.yaml` for workspace and pnpm-specific settings, and `.npmrc` for npm-compatible and pnpm-specific settings.
|
||||
|
||||
## pnpm-workspace.yaml
|
||||
|
||||
The recommended location for pnpm-specific configurations. Place at project root.
|
||||
|
||||
```yaml
|
||||
# Define workspace packages
|
||||
packages:
|
||||
- 'packages/*'
|
||||
- 'apps/*'
|
||||
- '!**/test/**' # Exclude pattern
|
||||
|
||||
# Catalog for shared dependency versions
|
||||
catalog:
|
||||
react: ^18.2.0
|
||||
typescript: ~5.3.0
|
||||
|
||||
# Named catalogs for different dependency groups
|
||||
catalogs:
|
||||
react17:
|
||||
react: ^17.0.2
|

|
||||
|
||||
# pnpm settings (alternative to .npmrc)
|
||||
settings:
|
||||
auto-install-peers: true
|
||||
strict-peer-dependencies: false
|
||||
link-workspace-packages: true
|
||||
prefer-workspace-packages: true
|
||||
shared-workspace-lockfile: true
|
||||
```
|
||||
|
||||
## .npmrc Settings
|
||||
|
||||
pnpm reads settings from `.npmrc` files. Create at project root or user home.
|
||||
|
||||
### Common pnpm Settings
|
||||
|
||||
```ini
|
||||
# Automatically install peer dependencies
|
||||
auto-install-peers=true
|
||||
|
||||
# Fail on peer dependency issues
|
||||
strict-peer-dependencies=false
|
||||
|
||||
# Hoist patterns for dependencies
|
||||
public-hoist-pattern[]=*types*
|
||||
public-hoist-pattern[]=*eslint*
|
||||
shamefully-hoist=false
|
||||
|
||||
# Store location
|
||||
store-dir=~/.pnpm-store
|
||||
|
||||
# Virtual store location
|
||||
virtual-store-dir=node_modules/.pnpm
|
||||
|
||||
# Lockfile settings
|
||||
lockfile=true
|
||||
prefer-frozen-lockfile=true
|
||||
|
||||
# Side effects cache (speeds up rebuilds)
|
||||
side-effects-cache=true
|
||||
|
||||
# Registry settings
|
||||
registry=https://registry.npmjs.org/
|
||||
@myorg:registry=https://npm.myorg.com/
|
||||
```
|
||||
|
||||
### Workspace Settings
|
||||
|
||||
```ini
|
||||
# Link workspace packages
|
||||
link-workspace-packages=true
|
||||
|
||||
# Prefer workspace packages over registry
|
||||
prefer-workspace-packages=true
|
||||
|
||||
# Single lockfile for all packages
|
||||
shared-workspace-lockfile=true
|
||||
|
||||
# Save prefix for workspace dependencies
|
||||
save-workspace-protocol=rolling
|
||||
```
|
||||
|
||||
### Node.js Settings
|
||||
|
||||
```ini
|
||||
# Use specific Node.js version
|
||||
use-node-version=20.10.0
|
||||
|
||||
# Node.js version file
|
||||
node-version-file=.nvmrc
|
||||
|
||||
# Manage Node.js versions
|
||||
manage-package-manager-versions=true
|
||||
```
|
||||
|
||||
### Security Settings
|
||||
|
||||
```ini
|
||||
# Ignore specific scripts
|
||||
ignore-scripts=false
|
||||
|
||||
# Allow specific build scripts
|
||||
onlyBuiltDependencies[]=esbuild
|
||||
onlyBuiltDependencies[]=sharp
|
||||
|
||||
# Package extensions for missing peer deps
|
||||
package-extensions[foo@1].peerDependencies.bar=*
|
||||
```
|
||||
|
||||
## Configuration Hierarchy
|
||||
|
||||
Settings are read in order (later overrides earlier):
|
||||
|
||||
1. `/etc/npmrc` - Global config
|
||||
2. `~/.npmrc` - User config
|
||||
3. `<project>/.npmrc` - Project config
|
||||
4. Environment variables: `npm_config_<key>=<value>`
|
||||
5. `pnpm-workspace.yaml` settings field
|
||||
|
||||
## Environment Variables
|
||||
|
||||
```bash
|
||||
# Set config via env
|
||||
npm_config_registry=https://registry.npmjs.org/
|
||||
|
||||
# pnpm-specific env vars
|
||||
PNPM_HOME=~/.local/share/pnpm
|
||||
```
|
||||
|
||||
## Package.json Fields
|
||||
|
||||
pnpm reads specific fields from `package.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"overrides": {
|
||||
"lodash": "^4.17.21"
|
||||
},
|
||||
"peerDependencyRules": {
|
||||
"ignoreMissing": ["@babel/*"],
|
||||
"allowedVersions": {
|
||||
"react": "17 || 18"
|
||||
}
|
||||
},
|
||||
"neverBuiltDependencies": ["fsevents"],
|
||||
"onlyBuiltDependencies": ["esbuild"],
|
||||
"allowedDeprecatedVersions": {
|
||||
"request": "*"
|
||||
},
|
||||
"patchedDependencies": {
|
||||
"express@4.18.2": "patches/express@4.18.2.patch"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Key Differences from npm/yarn
|
||||
|
||||
1. **Strict by default**: No phantom dependencies
|
||||
2. **Workspace protocol**: `workspace:*` for local packages
|
||||
3. **Catalogs**: Centralized version management
|
||||
4. **Content-addressable store**: Shared across projects

# pnpm Store
|
||||
|
||||
pnpm uses a content-addressable store to save disk space and speed up installations. All packages are stored once globally and hard-linked to project `node_modules`.
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Global Store**: Packages are downloaded once to a central store
|
||||
2. **Hard Links**: Projects link to store instead of copying files
|
||||
3. **Content-Addressable**: Files are stored by content hash, deduplicating identical files
|
||||
|
||||
### Storage Layout
|
||||
|
||||
```
|
||||
~/.pnpm-store/ # Global store (default location)
|
||||
└── v3/
|
||||
└── files/
|
||||
└── <hash>/ # Files stored by content hash
|
||||
|
||||
project/
|
||||
└── node_modules/
|
||||
├── .pnpm/ # Virtual store (hard links to global store)
|
||||
│ ├── lodash@4.17.21/
|
||||
│ │ └── node_modules/
|
||||
│ │ └── lodash/
|
||||
│ └── express@4.18.2/
|
||||
│ └── node_modules/
|
||||
│ ├── express/
|
||||
│ └── <deps>/ # Flat structure for dependencies
|
||||
├── lodash -> .pnpm/lodash@4.17.21/node_modules/lodash
|
||||
└── express -> .pnpm/express@4.18.2/node_modules/express
|
||||
```
|
||||
|
||||
## Store Commands
|
||||
|
||||
```bash
|
||||
# Show store location
|
||||
pnpm store path
|
||||
|
||||
# Remove unreferenced packages
|
||||
pnpm store prune
|
||||
|
||||
# Check store integrity
|
||||
pnpm store status
|
||||
|
||||
# Add package to store without installing
|
||||
pnpm store add <pkg>
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Store Location
|
||||
|
||||
```ini
|
||||
# .npmrc
|
||||
store-dir=~/.pnpm-store
|
||||
|
||||
# Or use environment variable
|
||||
PNPM_HOME=~/.local/share/pnpm
|
||||
```
|
||||
|
||||
### Virtual Store
|
||||
|
||||
The virtual store (`.pnpm` in `node_modules`) contains symlinks to the global store:
|
||||
|
||||
```ini
|
||||
# Customize virtual store location
|
||||
virtual-store-dir=node_modules/.pnpm
|
||||
|
||||
# Alternative flat layout
|
||||
node-linker=hoisted
|
||||
```
|
||||
|
||||
## Disk Space Benefits
|
||||
|
||||
pnpm saves significant disk space:
|
||||
|
||||
- **Deduplication**: Same package version stored once across all projects
|
||||
- **Content deduplication**: Identical files across different packages stored once
|
||||
- **Hard links**: No copying, just linking
|
||||
|
||||
### Check disk usage
|
||||
|
||||
```bash
|
||||
# Compare actual vs apparent size
|
||||
du -sh node_modules # Apparent size
|
||||
du -sh --apparent-size node_modules # With hard links counted
|
||||
```
|
||||
|
||||
## Node Linker Modes
|
||||
|
||||
Configure how `node_modules` is structured:
|
||||
|
||||
```ini
|
||||
# Default: Symlinked structure (recommended)
|
||||
node-linker=isolated
|
||||
|
||||
# Flat node_modules (npm-like, for compatibility)
|
||||
node-linker=hoisted
|
||||
|
||||
# PnP mode (experimental, like Yarn PnP)
|
||||
node-linker=pnp
|
||||
```
|
||||
|
||||
### Isolated Mode (Default)
|
||||
|
||||
- Strict dependency resolution
|
||||
- No phantom dependencies
|
||||
- Packages can only access declared dependencies
|
||||
|
||||
### Hoisted Mode
|
||||
|
||||
- Flat `node_modules` like npm
|
||||
- For compatibility with tools that don't support symlinks
|
||||
- Loses strictness benefits
|
||||
|
||||
## Side Effects Cache
|
||||
|
||||
Cache build outputs for native modules:
|
||||
|
||||
```ini
|
||||
# Enable side effects caching
|
||||
side-effects-cache=true
|
||||
|
||||
# Store side effects in project (instead of global store)
|
||||
side-effects-cache-readonly=true
|
||||
```
|
||||
|
||||
## Shared Store Across Machines
|
||||
|
||||
For CI/CD, you can share the store:
|
||||
|
||||
```yaml
|
||||
# GitHub Actions example
|
||||
- uses: pnpm/action-setup@v4
|
||||
with:
|
||||
run_install: false
|
||||
|
||||
- name: Get pnpm store directory
|
||||
shell: bash
|
||||
run: echo "STORE_PATH=$(pnpm store path --silent)" >> $GITHUB_ENV
|
||||
|
||||
- uses: actions/cache@v4
|
||||
with:
|
||||
path: ${{ env.STORE_PATH }}
|
||||
key: ${{ runner.os }}-pnpm-store-${{ hashFiles('**/pnpm-lock.yaml') }}
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Store corruption
|
||||
```bash
|
||||
# Verify and fix store
|
||||
pnpm store status
|
||||
pnpm store prune
|
||||
```
|
||||
|
||||
### Hard link issues (network drives, Docker)
|
||||
```ini
|
||||
# Use copying instead of hard links
|
||||
package-import-method=copy
|
||||
```
|
||||
|
||||
### Permission issues
|
||||
```bash
|
||||
# Fix store permissions
|
||||
chmod -R u+w ~/.pnpm-store
|
||||
```

## Setting Up Workspaces
|
||||
|
||||
Create `pnpm-workspace.yaml` at the repository root:
|
||||
|
||||
```yaml
|
||||
packages:
|
||||
# Include all packages in packages/ directory
|
||||
- 'packages/*'
|
||||
# Include all apps
|
||||
- 'apps/*'
|
||||
# Include nested packages
|
||||
- 'tools/*/packages/*'
|
||||
# Exclude test directories
|
||||
- '!**/test/**'
|
||||
```
|
||||
|
||||
## Workspace Protocol
|
||||
|
||||
Use `workspace:` protocol to reference local packages:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"@myorg/utils": "workspace:*",
|
||||
"@myorg/core": "workspace:^",
|
||||
"@myorg/types": "workspace:~"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Protocol Variants
|
||||
|
||||
| Protocol | Behavior | Published As |
|
||||
|----------|----------|--------------|
|
||||
| `workspace:*` | Any version | Actual version (e.g., `1.2.3`) |
|
||||
| `workspace:^` | Compatible version | `^1.2.3` |
|
||||
| `workspace:~` | Patch version | `~1.2.3` |
|
||||
| `workspace:^1.0.0` | Semver range | `^1.0.0` |
|
||||
|
||||
## Filtering Packages
|
||||
|
||||
Run commands on specific packages using `--filter`:
|
||||
|
||||
```bash
|
||||
# By package name
|
||||
pnpm --filter @myorg/app build
|
||||
pnpm -F @myorg/app build
|
||||
|
||||
# By directory path
|
||||
pnpm --filter "./packages/core" test
|
||||
|
||||
# Glob patterns
|
||||
pnpm --filter "@myorg/*" lint
|
||||
pnpm --filter "!@myorg/internal-*" publish
|
||||
|
||||
# All packages
|
||||
pnpm -r build
|
||||
pnpm --recursive build
|
||||
```
|
||||
|
||||
### Dependency-based Filtering
|
||||
|
||||
```bash
|
||||
# Package and all its dependencies
|
||||
pnpm --filter "...@myorg/app" build
|
||||
|
||||
# Package and all its dependents
|
||||
pnpm --filter "@myorg/core..." test
|
||||
|
||||
# Both directions
|
||||
pnpm --filter "...@myorg/shared..." build
|
||||
|
||||
# Changed since git ref
|
||||
pnpm --filter "...[origin/main]" test
|
||||
pnpm --filter "[HEAD~5]" lint
|
||||
```
|
||||
|
||||
## Workspace Commands
|
||||
|
||||
### Install dependencies
|
||||
```bash
|
||||
# Install all workspace packages
|
||||
pnpm install
|
||||
|
||||
# Add dependency to specific package
|
||||
pnpm --filter @myorg/app add lodash
|
||||
|
||||
# Add workspace dependency
|
||||
pnpm --filter @myorg/app add @myorg/utils
|
||||
```
|
||||
|
||||
### Run scripts
|
||||
```bash
|
||||
# Run in all packages with that script
|
||||
pnpm -r run build
|
||||
|
||||
# Run in topological order (dependencies first)
|
||||
pnpm -r --workspace-concurrency=1 run build
|
||||
|
||||
# Run in parallel
|
||||
pnpm -r --parallel run test
|
||||
|
||||
# Stream output
|
||||
pnpm -r --stream run dev
|
||||
```
|
||||
|
||||
### Execute commands
|
||||
```bash
|
||||
# Run command in all packages
|
||||
pnpm -r exec pwd
|
||||
|
||||
# Run in specific packages
|
||||
pnpm --filter "./packages/**" exec rm -rf dist
|
||||
```
|
||||
|
||||
## Workspace Settings
|
||||
|
||||
Configure in `.npmrc` or `pnpm-workspace.yaml`:
|
||||
|
||||
```ini
|
||||
# Link workspace packages automatically
|
||||
link-workspace-packages=true
|
||||
|
||||
# Prefer workspace packages over registry
|
||||
prefer-workspace-packages=true
|
||||
|
||||
# Single lockfile (recommended)
|
||||
shared-workspace-lockfile=true
|
||||
|
||||
# Workspace protocol handling
|
||||
save-workspace-protocol=rolling
|
||||
|
||||
# Concurrent workspace scripts
|
||||
workspace-concurrency=4
|
||||
```
|
||||
|
||||
## Publishing Workspaces
|
||||
|
||||
When publishing, `workspace:` protocols are converted:
|
||||
|
||||
```json
|
||||
// Before publish
|
||||
{
|
||||
"dependencies": {
|
||||
"@myorg/utils": "workspace:^"
|
||||
}
|
||||
}
|
||||
|
||||
// After publish
|
||||
{
|
||||
"dependencies": {
|
||||
"@myorg/utils": "^1.2.3"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Use `--no-git-checks` for publishing from CI:
|
||||
```bash
|
||||
pnpm publish -r --no-git-checks
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use workspace protocol** for internal dependencies
|
||||
2. **Enable `link-workspace-packages`** for automatic linking
|
||||
3. **Use shared lockfile** for consistency
|
||||
4. **Filter by dependencies** when building to ensure correct order
|
||||
5. **Use catalogs** for shared external dependency versions
|
||||
|
||||

|
||||
# pnpm Aliases
|
||||
|
||||
pnpm supports package aliases using the `npm:` protocol. This lets you install packages under different names, use multiple versions of the same package, or substitute packages.
|
||||
|
||||
## Basic Syntax
|
||||
|
||||
```bash
|
||||
pnpm add <alias>@npm:<package>@<version>
|
||||
```
|
||||
|
||||
In `package.json`:
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"<alias>": "npm:<package>@<version>"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Use Cases
|
||||
|
||||
### Multiple Versions of Same Package
|
||||
|
||||
Install different versions side by side:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"lodash3": "npm:lodash@3",
|
||||
"lodash4": "npm:lodash@4"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Usage:
|
||||
```js
|
||||
import lodash3 from 'lodash3'
|
||||
import lodash4 from 'lodash4'
|
||||
```
|
||||
|
||||
### Replace Package with Fork
|
||||
|
||||
Substitute a package with a fork or alternative:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"original-pkg": "npm:my-fork@^1.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
All imports of `original-pkg` will resolve to `my-fork`.
|
||||
|
||||
### Replace Deprecated Package
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"request": "npm:@cypress/request@^3.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Scoped to Unscoped (or vice versa)
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"vue": "npm:@anthropic/vue@^3.0.0",
|
||||
"@myorg/utils": "npm:lodash@^4.17.21"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## CLI Usage
|
||||
|
||||
### Add with alias
|
||||
|
||||
```bash
|
||||
# Add lodash under alias
|
||||
pnpm add lodash4@npm:lodash@4
|
||||
|
||||
# Add fork as original name
|
||||
pnpm add request@npm:@cypress/request
|
||||
```
|
||||
|
||||
### Add multiple versions
|
||||
|
||||
```bash
|
||||
pnpm add react17@npm:react@17 react18@npm:react@18
|
||||
```
|
||||
|
||||
## With TypeScript
|
||||
|
||||
For type resolution with aliases, you may need to configure TypeScript:
|
||||
|
||||
```json
|
||||
// tsconfig.json
|
||||
{
|
||||
"compilerOptions": {
|
||||
"paths": {
|
||||
"lodash3": ["node_modules/lodash3"],
|
||||
"lodash4": ["node_modules/lodash4"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or use `@types` packages with aliases:
|
||||
|
||||
```json
|
||||
{
|
||||
"devDependencies": {
|
||||
"@types/lodash3": "npm:@types/lodash@3",
|
||||
"@types/lodash4": "npm:@types/lodash@4"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Combined with Overrides
|
||||
|
||||
Force all transitive dependencies to use an alias:
|
||||
|
||||
```yaml
|
||||
# pnpm-workspace.yaml
|
||||
overrides:
|
||||
"underscore": "npm:lodash@^4.17.21"
|
||||
```
|
||||
|
||||
This replaces all `underscore` imports (including in dependencies) with lodash.
|
||||
|
||||
## Git and Local Aliases
|
||||
|
||||
Aliases work with any valid pnpm specifier:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"my-fork": "npm:user/repo#commit",
|
||||
"local-pkg": "file:../local-package"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Clear naming**: Use descriptive alias names that indicate purpose
|
||||
```json
|
||||
"lodash-legacy": "npm:lodash@3"
|
||||
"lodash-modern": "npm:lodash@4"
|
||||
```
|
||||
|
||||
2. **Document aliases**: Add comments or documentation explaining why aliases exist
|
||||
|
||||
3. **Prefer overrides for global replacement**: If you want to replace a package everywhere, use overrides instead of aliases
|
||||
|
||||
4. **Test thoroughly**: Aliased packages may have subtle differences in behavior

# pnpm Catalogs
|
||||
|
||||
Catalogs provide a centralized way to manage dependency versions across a workspace. Define versions once, use everywhere.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
Define a catalog in `pnpm-workspace.yaml`:
|
||||
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
|
||||
catalog:
|
||||
react: ^18.2.0
|
||||
react-dom: ^18.2.0
|
||||
typescript: ~5.3.0
|
||||
vite: ^5.0.0
|
||||
```
|
||||
|
||||
Reference in `package.json` with `catalog:`:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "catalog:",
|
||||
"react-dom": "catalog:"
|
||||
},
|
||||
"devDependencies": {
|
||||
"typescript": "catalog:",
|
||||
"vite": "catalog:"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Named Catalogs
|
||||
|
||||
Create multiple catalogs for different scenarios:
|
||||
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
|
||||
# Default catalog
|
||||
catalog:
|
||||
lodash: ^4.17.21
|
||||
|
||||
# Named catalogs
|
||||
catalogs:
|
||||
react17:
|
||||
react: ^17.0.2
|
||||
react-dom: ^17.0.2
|
||||
|
||||
react18:
|
||||
react: ^18.2.0
|
||||
react-dom: ^18.2.0
|
||||
|
||||
testing:
|
||||
vitest: ^1.0.0
|
||||
"@testing-library/react": ^14.0.0
|
||||
```
|
||||
|
||||
Reference named catalogs:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "catalog:react18",
|
||||
"react-dom": "catalog:react18"
|
||||
},
|
||||
"devDependencies": {
|
||||
"vitest": "catalog:testing"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **Single source of truth**: Update version in one place
|
||||
2. **Consistency**: All packages use the same version
|
||||
3. **Easy upgrades**: Change version once, affects entire workspace
|
||||
4. **Type-safe**: TypeScript support in pnpm-workspace.yaml
|
||||
|
||||
## Catalog vs Overrides
|
||||
|
||||
| Feature | Catalogs | Overrides |
|
||||
|---------|----------|-----------|
|
||||
| Purpose | Define versions for direct dependencies | Force versions for any dependency |
|
||||
| Scope | Direct dependencies only | All dependencies (including transitive) |
|
||||
| Usage | `"pkg": "catalog:"` | Applied automatically |
|
||||
| Opt-in | Explicit per package.json | Global to workspace |
|
||||
|
||||
## Publishing with Catalogs
|
||||
|
||||
When publishing, `catalog:` references are replaced with actual versions:
|
||||
|
||||
```json
|
||||
// Before publish (source)
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "catalog:"
|
||||
}
|
||||
}
|
||||
|
||||
// After publish (published package)
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "^18.2.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Migration from Overrides
|
||||
|
||||
If you're using overrides for version consistency:
|
||||
|
||||
```yaml
|
||||
# Before (using overrides)
|
||||
overrides:
|
||||
react: ^18.2.0
|
||||
react-dom: ^18.2.0
|
||||
```
|
||||
|
||||
Migrate to catalogs for cleaner dependency management:
|
||||
|
||||
```yaml
|
||||
# After (using catalogs)
|
||||
catalog:
|
||||
react: ^18.2.0
|
||||
react-dom: ^18.2.0
|
||||
```
|
||||
|
||||
Then update package.json files to use `catalog:`.
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use default catalog** for commonly shared dependencies
|
||||
2. **Use named catalogs** for version variants (e.g., different React versions)
|
||||
3. **Keep catalog minimal** - only include shared dependencies
|
||||
4. **Combine with workspace protocol** for internal packages
|
||||
|
||||
```yaml
|
||||
catalog:
|
||||
# External shared dependencies
|
||||
lodash: ^4.17.21
|
||||
zod: ^3.22.0
|
||||
|
||||
# Internal packages use workspace: protocol instead
|
||||
# "dependencies": { "@myorg/utils": "workspace:^" }
|
||||
```

# pnpm Hooks
|
||||
|
||||
pnpm provides hooks via `.pnpmfile.cjs` to customize how packages are resolved and their metadata is processed.
|
||||
|
||||
## Setup
|
||||
|
||||
Create `.pnpmfile.cjs` at workspace root:
|
||||
|
||||
```js
|
||||
// .pnpmfile.cjs
|
||||
function readPackage(pkg, context) {
|
||||
// Modify package metadata
|
||||
return pkg
|
||||
}
|
||||
|
||||
function afterAllResolved(lockfile, context) {
|
||||
// Modify lockfile
|
||||
return lockfile
|
||||
}
|
||||
|
||||
module.exports = {
|
||||
hooks: {
|
||||
readPackage,
|
||||
afterAllResolved
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## readPackage Hook
|
||||
|
||||
Called for every package before resolution. Use to modify dependencies, add missing peer deps, or fix broken packages.
|
||||
|
||||
### Add Missing Peer Dependency
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
if (pkg.name === 'some-broken-package') {
|
||||
pkg.peerDependencies = {
|
||||
...pkg.peerDependencies,
|
||||
react: '*'
|
||||
}
|
||||
context.log(`Added react peer dep to ${pkg.name}`)
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Override Dependency Version
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Fix all lodash versions
|
||||
if (pkg.dependencies?.lodash) {
|
||||
pkg.dependencies.lodash = '^4.17.21'
|
||||
}
|
||||
if (pkg.devDependencies?.lodash) {
|
||||
pkg.devDependencies.lodash = '^4.17.21'
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Remove Unwanted Dependency
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Remove optional dependency that causes issues
|
||||
if (pkg.optionalDependencies?.fsevents) {
|
||||
delete pkg.optionalDependencies.fsevents
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Replace Package
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Replace deprecated package
|
||||
if (pkg.dependencies?.['old-package']) {
|
||||
pkg.dependencies['new-package'] = pkg.dependencies['old-package']
|
||||
delete pkg.dependencies['old-package']
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Fix Broken Package
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Fix incorrect exports field
|
||||
if (pkg.name === 'broken-esm-package') {
|
||||
pkg.exports = {
|
||||
'.': {
|
||||
import: './dist/index.mjs',
|
||||
require: './dist/index.cjs'
|
||||
}
|
||||
}
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
## afterAllResolved Hook
|
||||
|
||||
Called after the lockfile is generated. Use for post-resolution modifications.
|
||||
|
||||
```js
|
||||
function afterAllResolved(lockfile, context) {
|
||||
// Log all resolved packages
|
||||
context.log(`Resolved ${Object.keys(lockfile.packages || {}).length} packages`)
|
||||
|
||||
// Modify lockfile if needed
|
||||
return lockfile
|
||||
}
|
||||
```
|
||||
|
||||
## Context Object
|
||||
|
||||
The `context` object provides utilities:
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Log messages
|
||||
context.log('Processing package...')
|
||||
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
## Use with TypeScript
|
||||
|
||||
For type hints, use JSDoc:
|
||||
|
||||
```js
|
||||
// .pnpmfile.cjs
|
||||
|
||||
/**
|
||||
* @param {import('type-fest').PackageJson} pkg
|
||||
* @param {{ log: (msg: string) => void }} context
|
||||
* @returns {import('type-fest').PackageJson}
|
||||
*/
|
||||
function readPackage(pkg, context) {
|
||||
return pkg
|
||||
}
|
||||
|
||||
module.exports = {
|
||||
hooks: {
|
||||
readPackage
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Conditional by Package Name
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
switch (pkg.name) {
|
||||
case 'package-a':
|
||||
pkg.dependencies.foo = '^2.0.0'
|
||||
break
|
||||
case 'package-b':
|
||||
delete pkg.optionalDependencies.bar
|
||||
break
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Apply to All Packages
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
// Remove all optional fsevents
|
||||
if (pkg.optionalDependencies) {
|
||||
delete pkg.optionalDependencies.fsevents
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
### Debug Resolution
|
||||
|
||||
```js
|
||||
function readPackage(pkg, context) {
|
||||
if (process.env.DEBUG_PNPM) {
|
||||
context.log(`${pkg.name}@${pkg.version}`)
|
||||
context.log(` deps: ${Object.keys(pkg.dependencies || {}).join(', ')}`)
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
```
|
||||
|
||||
## Hooks vs Overrides
|
||||
|
||||
| Feature | Hooks (.pnpmfile.cjs) | Overrides |
|
||||
|---------|----------------------|-----------|
|
||||
| Complexity | Can use JavaScript logic | Declarative only |
|
||||
| Scope | Any package metadata | Version only |
|
||||
| Use case | Complex fixes, conditional logic | Simple version pins |
|
||||
|
||||
**Prefer overrides** for simple version fixes. **Use hooks** when you need:
|
||||
- Conditional logic
|
||||
- Non-version modifications (exports, peer deps)
|
||||
- Logging/debugging
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Hook not running
|
||||
|
||||
1. Ensure file is named `.pnpmfile.cjs` (not `.js`)
|
||||
2. Check file is at workspace root
|
||||
3. Run `pnpm install` to trigger hooks
|
||||
|
||||
### Debug hooks
|
||||
|
||||
```bash
|
||||
# See hook logs
|
||||
pnpm install --reporter=append-only
|
||||
```

|
||||
# pnpm Overrides
|
||||
|
||||
Overrides let you force specific versions of packages, including transitive dependencies. Useful for fixing security vulnerabilities or compatibility issues.
|
||||
|
||||
## Basic Syntax
|
||||
|
||||
Define overrides in `pnpm-workspace.yaml` (recommended) or `package.json`:
|
||||
|
||||
### In pnpm-workspace.yaml (Recommended)
|
||||
|
||||
```yaml
|
||||
packages:
|
||||
- 'packages/*'
|
||||
|
||||
overrides:
|
||||
# Override all versions of a package
|
||||
lodash: ^4.17.21
|
||||
|
||||
# Override specific version range
|
||||
"foo@^1.0.0": ^1.2.3
|
||||
|
||||
# Override nested dependency
|
||||
"express>cookie": ^0.6.0
|
||||
|
||||
# Override to different package
|
||||
"underscore": "npm:lodash@^4.17.21"
|
||||
```
|
||||
|
||||
### In package.json
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"overrides": {
|
||||
"lodash": "^4.17.21",
|
||||
"foo@^1.0.0": "^1.2.3",
|
||||
"bar@^2.0.0>qux": "^1.0.0"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Override Patterns
|
||||
|
||||
### Override all instances
|
||||
```yaml
|
||||
overrides:
|
||||
lodash: ^4.17.21
|
||||
```
|
||||
Forces all lodash installations to use ^4.17.21.
|
||||
|
||||
### Override specific parent version
|
||||
```yaml
|
||||
overrides:
|
||||
"foo@^1.0.0": ^1.2.3
|
||||
```
|
||||
Only override foo when the requested version matches ^1.0.0.
|
||||
|
||||
### Override nested dependency
|
||||
```yaml
|
||||
overrides:
|
||||
"express>cookie": ^0.6.0
|
||||
"foo@1.x>bar@^2.0.0>qux": ^1.0.0
|
||||
```
|
||||
Override cookie only when it's a dependency of express.
|
||||
|
||||
### Replace with different package
|
||||
```yaml
|
||||
overrides:
|
||||
# Replace underscore with lodash
|
||||
"underscore": "npm:lodash@^4.17.21"
|
||||
|
||||
# Use local file
|
||||
"some-pkg": "file:./local-pkg"
|
||||
|
||||
# Use git
|
||||
"some-pkg": "github:user/repo#commit"
|
||||
```
|
||||
|
||||
### Remove a dependency
|
||||
```yaml
|
||||
overrides:
|
||||
"unwanted-pkg": "-"
|
||||
```
|
||||
The `-` removes the package entirely.
|
||||
|
||||
## Common Use Cases
|
||||
|
||||
### Security Fix
|
||||
|
||||
Force patched version of vulnerable package:
|
||||
|
||||
```yaml
|
||||
overrides:
|
||||
# Fix CVE in transitive dependency
|
||||
"minimist": "^1.2.6"
|
||||
"json5": "^2.2.3"
|
||||
```
|
||||
|
||||
### Deduplicate Dependencies
|
||||
|
||||
Force single version when multiple are installed:
|
||||
|
||||
```yaml
|
||||
overrides:
|
||||
"react": "^18.2.0"
|
||||
"react-dom": "^18.2.0"
|
||||
```
|
||||
|
||||
### Fix Peer Dependency Issues
|
||||
|
||||
```yaml
|
||||
overrides:
|
||||
"@types/react": "^18.2.0"
|
||||
```
|
||||
|
||||
### Replace Deprecated Package
|
||||
|
||||
```yaml
|
||||
overrides:
|
||||
"request": "npm:@cypress/request@^3.0.0"
|
||||
```
|
||||
|
||||
## Hooks Alternative
|
||||
|
||||
For more complex scenarios, use `.pnpmfile.cjs`:
|
||||
|
||||
```js
|
||||
// .pnpmfile.cjs
|
||||
function readPackage(pkg, context) {
|
||||
// Override dependency version
|
||||
if (pkg.dependencies?.lodash) {
|
||||
pkg.dependencies.lodash = '^4.17.21'
|
||||
}
|
||||
|
||||
// Add missing peer dependency
|
||||
if (pkg.name === 'some-package') {
|
||||
pkg.peerDependencies = {
|
||||
...pkg.peerDependencies,
|
||||
react: '*'
|
||||
}
|
||||
}
|
||||
|
||||
return pkg
|
||||
}
|
||||
|
||||
module.exports = {
|
||||
hooks: {
|
||||
readPackage
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Overrides vs Catalogs
|
||||
|
||||
| Feature | Overrides | Catalogs |
|
||||
|---------|-----------|----------|
|
||||
| Affects | All dependencies (including transitive) | Direct dependencies only |
|
||||
| Usage | Automatic | Explicit `catalog:` reference |
|
||||
| Purpose | Force versions, fix issues | Version management |
|
||||
| Granularity | Can target specific parents | Package-wide only |
|
||||
|
||||
## Debugging
|
||||
|
||||
Check which version is resolved:
|
||||
|
||||
```bash
|
||||
# See resolved versions
|
||||
pnpm why lodash
|
||||
|
||||
# List all versions
|
||||
pnpm list lodash --depth=Infinity
|
||||
```

description: Patch third-party packages directly with customized fixes

|

# pnpm Patches
|
||||
|
||||
pnpm's patching feature lets you modify third-party packages directly. Useful for applying fixes before upstream releases or customizing package behavior.
|
||||
|
||||
## Creating a Patch
|
||||
|
||||
### Step 1: Initialize Patch
|
||||
|
||||
```bash
|
||||
pnpm patch <pkg>@<version>
|
||||
|
||||
# Example
|
||||
pnpm patch express@4.18.2
|
||||
```
|
||||
|
||||
This creates a temporary directory with the package source and outputs the path:
|
||||
|
||||
```
|
||||
You can now edit the following folder: /tmp/abc123...
|
||||
```
|
||||
|
||||
### Step 2: Edit Files
|
||||
|
||||
Navigate to the temporary directory and make your changes:
|
||||
|
||||
```bash
|
||||
cd /tmp/abc123...
|
||||
# Edit files as needed
|
||||
```
|
||||
|
||||
### Step 3: Commit Patch
|
||||
|
||||
```bash
|
||||
pnpm patch-commit <path-from-step-1>
|
||||
|
||||
# Example
|
||||
pnpm patch-commit /tmp/abc123...
|
||||
```
|
||||
|
||||
This creates a `.patch` file in `patches/` and updates `package.json`:
|
||||
|
||||
```
|
||||
patches/
|
||||
└── express@4.18.2.patch
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"patchedDependencies": {
|
||||
"express@4.18.2": "patches/express@4.18.2.patch"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Patch File Format
|
||||
|
||||
Patches use standard unified diff format:
|
||||
|
||||
```diff
|
||||
diff --git a/lib/router/index.js b/lib/router/index.js
|
||||
index abc123..def456 100644
|
||||
--- a/lib/router/index.js
|
||||
+++ b/lib/router/index.js
|
||||
@@ -100,6 +100,7 @@ function createRouter() {
|
||||
// Original code
|
||||
- const timeout = 30000;
|
||||
+ const timeout = 60000; // Extended timeout
|
||||
return router;
|
||||
}
|
||||
```
|
||||
|
||||
## Managing Patches
|
||||
|
||||
### List Patched Packages
|
||||
|
||||
```bash
|
||||
pnpm list --depth=0
|
||||
# Shows (patched) marker for patched packages
|
||||
```
|
||||
|
||||
### Update a Patch
|
||||
|
||||
```bash
|
||||
# Edit existing patch
|
||||
pnpm patch express@4.18.2
|
||||
|
||||
# After editing
|
||||
pnpm patch-commit <path>
|
||||
```
|
||||
|
||||
### Remove a Patch
|
||||
|
||||
```bash
|
||||
pnpm patch-remove <pkg>@<version>
|
||||
|
||||
# Example
|
||||
pnpm patch-remove express@4.18.2
|
||||
```
|
||||
|
||||
Or manually:
|
||||
1. Delete the patch file from `patches/`
|
||||
2. Remove entry from `patchedDependencies` in `package.json`
|
||||
3. Run `pnpm install`
|
||||
|
||||
## Patch Configuration
|
||||
|
||||
### Custom Patches Directory
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"patchedDependencies": {
|
||||
"express@4.18.2": "custom-patches/my-express-fix.patch"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Multiple Packages
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"patchedDependencies": {
|
||||
"express@4.18.2": "patches/express@4.18.2.patch",
|
||||
"lodash@4.17.21": "patches/lodash@4.17.21.patch",
|
||||
"@types/node@20.10.0": "patches/@types__node@20.10.0.patch"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Workspaces
|
||||
|
||||
Patches are shared across the workspace. Define in the root `package.json`:
|
||||
|
||||
```json
|
||||
// Root package.json
|
||||
{
|
||||
"pnpm": {
|
||||
"patchedDependencies": {
|
||||
"express@4.18.2": "patches/express@4.18.2.patch"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
All workspace packages using `express@4.18.2` will have the patch applied.
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Version specificity**: Patches are tied to exact versions. Update patches when upgrading dependencies.
|
||||
|
||||
2. **Document patches**: Add comments explaining why the patch exists:
|
||||
```bash
|
||||
# In patches/README.md
|
||||
## express@4.18.2.patch
|
||||
Fixes timeout issue. PR pending: https://github.com/expressjs/express/pull/1234
|
||||
```
|
||||
|
||||
3. **Minimize patches**: Keep patches small and focused. Large patches are hard to maintain.
|
||||
|
||||
4. **Track upstream**: Note upstream issues/PRs so you can remove patches when fixed.
|
||||
|
||||
5. **Test patches**: Ensure patched code works correctly in your use case.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Patch fails to apply
|
||||
|
||||
```
|
||||
ERR_PNPM_PATCH_FAILED Cannot apply patch
|
||||
```
|
||||
|
||||
The package version changed. Recreate the patch:
|
||||
```bash
|
||||
pnpm patch-remove express@4.18.2
|
||||
pnpm patch express@4.18.2
|
||||
# Reapply changes
|
||||
pnpm patch-commit <path>
|
||||
```
|
||||
|
||||
### Patch not applied
|
||||
|
||||
Ensure:
|
||||
1. Version in `patchedDependencies` matches installed version exactly
|
||||
2. Run `pnpm install` after adding patch configuration

description: Handling peer dependencies with auto-install and resolution rules

---
|
||||
|
||||
# pnpm Peer Dependencies
|
||||
|
||||
pnpm has strict peer dependency handling by default. It provides configuration options to control how peer dependencies are resolved and reported.
|
||||
|
||||
## Auto-Install Peer Dependencies
|
||||
|
||||
By default, pnpm automatically installs peer dependencies:
|
||||
|
||||
```ini
|
||||
# .npmrc (default is true since pnpm v8)
|
||||
auto-install-peers=true
|
||||
```
|
||||
|
||||
When enabled, pnpm automatically adds missing peer dependencies based on the best matching version.
|
||||
|
||||
## Strict Peer Dependencies
|
||||
|
||||
Control whether peer dependency issues cause errors:
|
||||
|
||||
```ini
|
||||
# Fail on peer dependency issues (default: false)
|
||||
strict-peer-dependencies=true
|
||||
```
|
||||
|
||||
When strict, pnpm will fail if:
|
||||
- Peer dependency is missing
|
||||
- Installed version doesn't match required range
|
||||
|
||||
## Peer Dependency Rules
|
||||
|
||||
Configure peer dependency behavior in `package.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"ignoreMissing": ["@babel/*", "eslint"],
|
||||
"allowedVersions": {
|
||||
"react": "17 || 18"
|
||||
},
|
||||
"allowAny": ["@types/*"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### ignoreMissing
|
||||
|
||||
Suppress warnings for missing peer dependencies:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"ignoreMissing": [
|
||||
"@babel/*",
|
||||
"eslint",
|
||||
"webpack"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Use patterns:
|
||||
- `"react"` - exact package name
|
||||
- `"@babel/*"` - all packages in scope
|
||||
- `"*"` - all packages (not recommended)
|
||||
|
||||
### allowedVersions
|
||||
|
||||
Allow specific versions that would otherwise cause warnings:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"allowedVersions": {
|
||||
"react": "17 || 18",
|
||||
"webpack": "4 || 5",
|
||||
"@types/react": "*"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### allowAny
|
||||
|
||||
Allow any version for specified peer dependencies:
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"allowAny": ["@types/*", "eslint"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Adding Peer Dependencies via Hooks
|
||||
|
||||
Use `.pnpmfile.cjs` to add missing peer dependencies:
|
||||
|
||||
```js
|
||||
// .pnpmfile.cjs
|
||||
function readPackage(pkg, context) {
|
||||
// Add missing peer dependency
|
||||
if (pkg.name === 'problematic-package') {
|
||||
pkg.peerDependencies = {
|
||||
...pkg.peerDependencies,
|
||||
react: '*'
|
||||
}
|
||||
}
|
||||
return pkg
|
||||
}
|
||||
|
||||
module.exports = {
|
||||
hooks: {
|
||||
readPackage
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Peer Dependencies in Workspaces
|
||||
|
||||
Workspace packages can satisfy peer dependencies:
|
||||
|
||||
```json
|
||||
// packages/app/package.json
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "^18.2.0",
|
||||
"@myorg/components": "workspace:^"
|
||||
}
|
||||
}
|
||||
|
||||
// packages/components/package.json
|
||||
{
|
||||
"peerDependencies": {
|
||||
"react": "^17.0.0 || ^18.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The workspace `app` provides `react` which satisfies `components`' peer dependency.
|
||||
|
||||
## Common Scenarios
|
||||
|
||||
### Monorepo with Shared React
|
||||
|
||||
```yaml
|
||||
# pnpm-workspace.yaml
|
||||
catalog:
|
||||
react: ^18.2.0
|
||||
react-dom: ^18.2.0
|
||||
```
|
||||
|
||||
```json
|
||||
// packages/ui/package.json
|
||||
{
|
||||
"peerDependencies": {
|
||||
"react": "^18.0.0",
|
||||
"react-dom": "^18.0.0"
|
||||
}
|
||||
}
|
||||
|
||||
// apps/web/package.json
|
||||
{
|
||||
"dependencies": {
|
||||
"react": "catalog:",
|
||||
"react-dom": "catalog:",
|
||||
"@myorg/ui": "workspace:^"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Suppress ESLint Plugin Warnings
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"ignoreMissing": [
|
||||
"eslint",
|
||||
"@typescript-eslint/parser"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Allow Multiple Major Versions
|
||||
|
||||
```json
|
||||
{
|
||||
"pnpm": {
|
||||
"peerDependencyRules": {
|
||||
"allowedVersions": {
|
||||
"webpack": "4 || 5",
|
||||
"postcss": "7 || 8"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Debugging Peer Dependencies
|
||||
|
||||
```bash
|
||||
# See why a package is installed
|
||||
pnpm why <package>
|
||||
|
||||
# List all peer dependency warnings
|
||||
pnpm install --reporter=append-only 2>&1 | grep -i peer
|
||||
|
||||
# Check dependency tree
|
||||
pnpm list --depth=Infinity
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Enable auto-install-peers** for convenience (default in pnpm v8+)
|
||||
|
||||
2. **Use peerDependencyRules** instead of ignoring all warnings
|
||||
|
||||
3. **Document suppressed warnings** explaining why they're safe
|
||||
|
||||
4. **Keep peer deps ranges wide** in libraries:
|
||||
```json
|
||||
{
|
||||
"peerDependencies": {
|
||||
"react": "^17.0.0 || ^18.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
5. **Test with different peer versions** if you support multiple majors

|
||||
|
||||
## Quick Reference
|
||||
|
||||
### Collection Design (CRITICAL)
|
||||
- **coll-field-types**: Use appropriate field types (json for objects, select for enums)
|
||||
- **coll-auth-vs-base**: Extend auth collection for users, base for non-auth data
|
||||
- **coll-relations**: Use relation fields, not manual ID strings
|
||||
- **coll-indexes**: Create indexes on frequently filtered/sorted fields
|
||||
- **coll-view-collections**: Use views for complex aggregations
|
||||
- **coll-geopoint**: Store coordinates as json field with lat/lng
|
||||
|
||||
### API Rules (CRITICAL)
|
||||
- **rules-basics**: Always set API rules; empty = public access
|
||||
- **rules-filter-syntax**: Use @request.auth, @collection, @now in rules
|
||||
- **rules-request-context**: Access request data via @request.body, @request.query; `@request.context` values: `default`/`oauth2`/`otp`/`password`/`realtime`/`protectedFile`
|
||||
- **rules-cross-collection**: Use @collection.name.field for cross-collection checks
|
||||
- **rules-locked-vs-open**: Start locked, open selectively
|
||||
- **rules-strftime**: Use `strftime('%Y-%m-%d', created)` for date arithmetic (v0.36+)
|
||||
|
||||
### Authentication (CRITICAL)
|
||||
- **auth-password**: Use authWithPassword for email/password login
|
||||
- **auth-oauth2**: Configure OAuth2 providers via Admin UI
|
||||
- **auth-otp**: Two-step `requestOTP` → `authWithOTP`; rate-limit requestOTP and never leak email existence
|
||||
- **auth-token-management**: Store tokens securely, refresh before expiry
|
||||
- **auth-mfa**: Enable MFA for sensitive applications
|
||||
- **auth-impersonation**: Use impersonation for admin actions on behalf of users
|
||||
|
||||
### SDK Usage (HIGH)
|
||||
- **sdk-initialization**: Initialize client once, reuse instance
|
||||
- **sdk-auth-store**: Use AsyncAuthStore for React Native/SSR
|
||||
- **sdk-error-handling**: Catch ClientResponseError, check status codes
|
||||
- **sdk-auto-cancellation**: Disable auto-cancel for concurrent requests
|
||||
- **sdk-filter-binding**: Use filter binding to prevent injection
|
||||
|
||||
### Query Performance (HIGH)
|
||||
- **query-expand**: Expand relations to avoid N+1 queries
|
||||
- **query-field-selection**: Select only needed fields
|
||||
- **query-pagination**: Use cursor pagination for large datasets
|
||||
- **query-batch-operations**: Batch creates/updates when possible
|
||||
|
||||
### Realtime (MEDIUM)
|
||||
- **realtime-subscribe**: Subscribe to specific records or collections
|
||||
- **realtime-events**: Handle create, update, delete events separately
|
||||
- **realtime-auth**: Realtime respects API rules automatically
|
||||
- **realtime-reconnection**: Implement reconnection logic
|
||||
|
||||
### File Handling (MEDIUM)
|
||||
- **file-upload**: Use FormData for uploads, set proper content types
|
||||
- **file-serving**: Use pb.files.getURL() for file URLs
|
||||
- **file-validation**: Validate file types and sizes server-side
|
||||
|
||||
### Deployment (MEDIUM)
|
||||
- **deploy-backup**: Schedule regular backups of pb_data
|
||||
- **deploy-configuration**: Use environment variables for config
|
||||
- **deploy-reverse-proxy**: Put behind nginx/caddy in production
|
||||
- **deploy-sqlite-considerations**: Optimize SQLite for production workloads
|
||||
- **deploy-rate-limiting**: Enable the built-in rate limiter (fixed-window as of v0.36.7); front with Nginx/Caddy for defense in depth
|
||||
- **deploy-scaling**: Raise `ulimit -n` for realtime, set `GOMEMLIMIT`, enable settings encryption
|
||||
|
||||
### Server-Side Extending (HIGH)
|
||||
- **ext-go-setup**: Use `app.OnServe()` to register routes; use `e.App` inside hooks, not the parent-scope app
|
||||
- **ext-js-setup**: Drop `*.pb.js` in `pb_hooks/`; add `/// <reference path="../pb_data/types.d.ts" />`
|
||||
- **ext-hooks-chain**: Always call `e.Next()`/`e.next()`; use `Bind` with an Id for later `Unbind`
|
||||
- **ext-hooks-record-vs-request**: Use `OnRecordEnrich` to shape responses (incl. realtime); `OnRecordRequest` for HTTP-only
|
||||
- **ext-routing-custom**: Namespace routes under `/api/{yourapp}/`; attach `RequireAuth()` middleware
|
||||
- **ext-transactions**: Use the scoped `txApp` inside `RunInTransaction`; never capture the outer `app`
|
||||
- **ext-filter-binding-server**: Bind user input with `{:name}` + `dbx.Params` in `FindFirstRecordByFilter` / `FindRecordsByFilter`
|
||||
- **ext-filesystem**: `defer fs.Close()` on every `NewFilesystem()` / `NewBackupsFilesystem()` handle
|
||||
- **ext-cron-jobs**: Register with `app.Cron().MustAdd(id, expr, fn)` / `cronAdd()`; stable ids, no `__pb*__` prefix
|
||||
- **ext-go-migrations**: Versioned `.go` files under `migrations/`; `Automigrate: osutils.IsProbablyGoRun()`
|
||||
- **ext-js-migrations**: `pb_migrations/<unix>_*.js` with `migrate(upFn, downFn)`; auto-discovered by filename
|
||||
- **ext-mailer**: Resolve sender from `app.Settings().Meta` at send-time; never ship `no-reply@example.com`; create the mail client per send
|
||||
- **ext-settings**: Read via `app.Settings()` at call time; set `PB_ENCRYPTION` (32 chars) to encrypt `_params` at rest
|
||||
- **ext-testing**: `tests.NewTestApp(testDataDir)` + `tests.ApiScenario`; `defer app.Cleanup()`, assert `ExpectedEvents`
|
||||
- **ext-compose-request-flow**: Composite walkthrough showing which app instance is active at each layer (route → tx → hook → enrich)
|
||||
- **ext-go-custom-sqlite**: Only use `DBConnect` when you need FTS5/ICU; `DBConnect` is called twice (data.db + auxiliary.db)
|
||||
- **ext-jsvm-scope**: Variables outside handlers are undefined at runtime — load shared config via `require()` inside the handler
|
||||
- **ext-jsvm-modules**: Only CJS (`require()`) works in goja; bundle ESM first; avoid mutable module state
|
||||

# API Rules & Security
|
||||
|
||||
**Impact: CRITICAL**
|
||||
|
||||
Access control rules, filter expressions, request context usage, and security patterns. Critical for protecting data and enforcing authorization.
|
||||
|
||||
---
|
||||
|
||||
## 1. Understand API Rule Types and Defaults
|
||||
|
||||
**Impact: CRITICAL (Prevents unauthorized access, data leaks, and security vulnerabilities)**
|
||||
|
||||
PocketBase uses five collection-level rules to control access. Understanding the difference between locked (null), open (""), and expression rules is critical for security.
|
||||
|
||||
**Incorrect (leaving rules open unintentionally):**
|
||||
|
||||
```javascript
|
||||
// Collection with overly permissive rules
|
||||
const collection = {
|
||||
name: 'messages',
|
||||
listRule: '', // Anyone can list all messages!
|
||||
viewRule: '', // Anyone can view any message!
|
||||
createRule: '', // Anyone can create messages!
|
||||
updateRule: '', // Anyone can update any message!
|
||||
deleteRule: '' // Anyone can delete any message!
|
||||
};
|
||||
// Complete security bypass - all data exposed
|
||||
```
|
||||
|
||||
**Correct (explicit, restrictive rules):**
|
||||
|
||||
```javascript
|
||||
// Collection with proper access control
|
||||
const collection = {
|
||||
name: 'messages',
|
||||
// null = locked, only superusers can access
|
||||
listRule: null, // Default: locked to superusers
|
||||
|
||||
// '' (empty string) = open to everyone (use sparingly)
|
||||
viewRule: '@request.auth.id != ""', // Any authenticated user
|
||||
|
||||
// Expression = conditional access
|
||||
createRule: '@request.auth.id != ""', // Must be logged in
|
||||
updateRule: 'author = @request.auth.id', // Only author
|
||||
deleteRule: 'author = @request.auth.id' // Only author
|
||||
};
|
||||
```
|
||||
|
||||
**Rule types explained:**
|
||||
|
||||
| Rule Value | Meaning | Use Case |
|
||||
|------------|---------|----------|
|
||||
| `null` | Locked (superusers only) | Admin-only data, system tables |
|
||||
| `''` (empty string) | Open to everyone | Public content, no auth required |
|
||||
| `'expression'` | Conditional access | Most common - check auth, ownership |
|
||||
|
||||
**Common patterns:**
|
||||
|
||||
```javascript
|
||||
// Public read, authenticated write (enforce ownership on create)
|
||||
listRule: '',
|
||||
viewRule: '',
|
||||
createRule: '@request.auth.id != "" && @request.body.author = @request.auth.id',
|
||||
updateRule: 'author = @request.auth.id',
|
||||
deleteRule: 'author = @request.auth.id'
|
||||
|
||||
// Private to owner only
|
||||
listRule: 'owner = @request.auth.id',
|
||||
viewRule: 'owner = @request.auth.id',
|
||||
createRule: '@request.auth.id != ""',
|
||||
updateRule: 'owner = @request.auth.id',
|
||||
deleteRule: 'owner = @request.auth.id'
|
||||
|
||||
// Read-only public data
|
||||
listRule: '',
|
||||
viewRule: '',
|
||||
createRule: null,
|
||||
updateRule: null,
|
||||
deleteRule: null
|
||||
```
|
||||
|
||||
**Error responses by rule type:**
|
||||
- List rule fail: 200 with empty items
|
||||
- View/Update/Delete fail: 404 (hides existence)
|
||||
- Create fail: 400
|
||||
- Locked rule violation: 403
|
||||
|
||||
Reference: [PocketBase API Rules](https://pocketbase.io/docs/api-rules-and-filters/)
|
||||
|
||||
## 2. Use @collection for Cross-Collection Lookups
|
||||
|
||||
**Impact: HIGH (Enables complex authorization without denormalization)**
|
||||
|
||||
The `@collection` reference allows rules to query other collections, enabling complex authorization patterns like role-based access, team membership, and resource permissions.
|
||||
|
||||
**Incorrect (denormalizing data for access control):**
|
||||
|
||||
```javascript
|
||||
// Duplicating team membership in every resource
|
||||
const documentsSchema = [
|
||||
{ name: 'title', type: 'text' },
|
||||
{ name: 'team', type: 'relation' },
|
||||
// Duplicated member list for access control - gets out of sync!
|
||||
{ name: 'allowedUsers', type: 'relation', options: { maxSelect: 999 } }
|
||||
];
|
||||
|
||||
// Rule checks duplicated data
|
||||
listRule: 'allowedUsers ?= @request.auth.id'
|
||||
// Problem: must update allowedUsers whenever team membership changes
|
||||
```
|
||||
|
||||
**Correct (using @collection lookup):**
|
||||
|
||||
```javascript
|
||||
// Clean schema - no duplication
|
||||
const documentsSchema = [
|
||||
{ name: 'title', type: 'text' },
|
||||
{ name: 'team', type: 'relation', options: { collectionId: 'teams' } }
|
||||
];
|
||||
|
||||
// Check team membership via @collection lookup
|
||||
listRule: '@collection.team_members.user ?= @request.auth.id && @collection.team_members.team ?= team'
|
||||
|
||||
// Alternative: check if user is in team's members array
|
||||
listRule: 'team.members ?= @request.auth.id'
|
||||
|
||||
// Role-based access via separate roles collection
|
||||
listRule: '@collection.user_roles.user = @request.auth.id && @collection.user_roles.role = "admin"'
|
||||
```
|
||||
|
||||
**Common patterns:**
|
||||
|
||||
```javascript
|
||||
// Team-based access
|
||||
// teams: { name, members (relation to users) }
|
||||
// documents: { title, team (relation to teams) }
|
||||
viewRule: 'team.members ?= @request.auth.id'
|
||||
|
||||
// Organization hierarchy
|
||||
// orgs: { name }
|
||||
// org_members: { org, user, role }
|
||||
// projects: { name, org }
|
||||
listRule: '@collection.org_members.org = org && @collection.org_members.user = @request.auth.id'
|
||||
|
||||
// Permission-based access
|
||||
// permissions: { resource, user, level }
|
||||
updateRule: '@collection.permissions.resource = id && @collection.permissions.user = @request.auth.id && @collection.permissions.level = "write"'
|
||||
|
||||
// Using aliases for complex queries
|
||||
listRule: '@collection.memberships:m.user = @request.auth.id && @collection.memberships:m.team = team'
|
||||
```
|
||||
|
||||
**Performance considerations:**
|
||||
- Cross-collection lookups add query complexity
|
||||
- Ensure referenced fields are indexed
|
||||
- Consider caching for frequently accessed permissions
|
||||
- Test performance with realistic data volumes
|
||||
|
||||

|
||||
|
||||
## 3. Master Filter Expression Syntax
|
||||
|
||||
**Impact: CRITICAL (Enables complex access control and efficient querying)**
|
||||
|
||||
PocketBase filter expressions use a specific syntax for both API rules and client-side queries. Understanding operators and composition is essential.
|
||||
|
||||
**Incorrect (invalid filter syntax):**
|
||||
|
||||
```javascript
|
||||
// Wrong operator syntax
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'status == "published"' // Wrong: == instead of =
|
||||
});
|
||||
|
||||
// Missing quotes around strings
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'status = published' // Wrong: unquoted string
|
||||
});
|
||||
|
||||
// Wrong boolean logic
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'status = "published" AND featured = true' // Wrong: AND instead of &&
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (proper filter syntax):**
|
||||
|
||||
```javascript
|
||||
// Equality and comparison operators
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'status = "published"' // Equals
|
||||
});
|
||||
filter: 'views != 0' // Not equals
|
||||
filter: 'views > 100' // Greater than
|
||||
filter: 'views >= 100' // Greater or equal
|
||||
filter: 'price < 50.00' // Less than
|
||||
filter: 'created <= "2024-01-01 00:00:00"' // Less or equal
|
||||
|
||||
// String operators
|
||||
filter: 'title ~ "hello"' // Contains (case-insensitive)
|
||||
filter: 'title !~ "spam"' // Does not contain
|
||||
|
||||
// Logical operators
|
||||
filter: 'status = "published" && featured = true' // AND
|
||||
filter: 'category = "news" || category = "blog"' // OR
|
||||
filter: '(status = "draft" || status = "review") && author = "abc"' // Grouping
|
||||
|
||||
// Array/multi-value operators (for select, relation fields)
|
||||
filter: 'tags ?= "featured"' // Any tag equals "featured"
|
||||
filter: 'tags ?~ "tech"' // Any tag contains "tech"
|
||||
|
||||
// Null checks
|
||||
filter: 'deletedAt = null' // Is null
|
||||
filter: 'avatar != null' // Is not null
|
||||
|
||||
// Date comparisons
|
||||
filter: 'created > "2024-01-01 00:00:00"'
|
||||
filter: 'created >= @now' // Current timestamp
|
||||
filter: 'expires < @today' // Start of today (UTC)
|
||||
```
|
||||
|
||||
**Available operators:**
|
||||
|
||||
| Operator | Description |
|
||||
|----------|-------------|
|
||||
| `=` | Equal |
|
||||
| `!=` | Not equal |
|
||||
| `>` `>=` `<` `<=` | Comparison |
|
||||
| `~` | Contains (LIKE %value%) |
|
||||
| `!~` | Does not contain |
|
||||
| `?=` `?!=` `?>` `?~` | Any element matches |
|
||||
| `&&` | AND |
|
||||
| `\|\|` | OR |
|
||||
| `()` | Grouping |
|
||||
|
||||
**Date macros:**
|
||||
- `@now` - Current UTC datetime
|
||||
- `@today` - Start of today UTC
|
||||
- `@month` - Start of current month UTC
|
||||
- `@year` - Start of current year UTC
|
||||
|
||||
**Filter functions:**
|
||||
- `strftime(fmt, datetime)` - Format/extract datetime parts (v0.36+). E.g. `strftime('%Y-%m', created) = "2026-03"`. See `rules-strftime.md` for the full format specifier list.
|
||||
- `length(field)` - Element count of a multi-value field (file, relation, select). E.g. `length(tags) > 0`.
|
||||
- `each(field, expr)` - Iterate a multi-value field: `each(tags, ? ~ "urgent")`.
|
||||
- `issetIf(field, val)` - Conditional presence check for complex rules.
|
||||

||||

|
||||
|
||||
## 4. Default to Locked Rules, Open Explicitly
|
||||
|
||||
**Impact: CRITICAL (Defense in depth, prevents accidental data exposure)**
|
||||
|
||||
New collections should start with locked (null) rules and explicitly open only what's needed. This prevents accidental data exposure and follows the principle of least privilege.
|
||||
|
||||
**Incorrect (starting with open rules):**
|
||||
|
||||
```javascript
|
||||
// Dangerous: copying rules from examples without thinking
|
||||
const collection = {
|
||||
name: 'user_settings',
|
||||
listRule: '', // Open - leaks all user settings!
|
||||
viewRule: '', // Open - anyone can view any setting
|
||||
createRule: '', // Open - no auth required
|
||||
updateRule: '', // Open - anyone can modify!
|
||||
deleteRule: '' // Open - anyone can delete!
|
||||
};
|
||||
|
||||
// Also dangerous: using auth check when ownership needed
|
||||
const collection = {
|
||||
name: 'private_notes',
|
||||
listRule: '@request.auth.id != ""', // Any logged-in user sees ALL notes
|
||||
viewRule: '@request.auth.id != ""',
|
||||
updateRule: '@request.auth.id != ""', // Any user can edit ANY note!
|
||||
};
|
||||
```
|
||||
|
||||
**Correct (locked by default, explicitly opened):**
|
||||
|
||||
```javascript
|
||||
// Step 1: Start locked
|
||||
const collection = {
|
||||
name: 'user_settings',
|
||||
listRule: null, // Locked - superusers only
|
||||
viewRule: null,
|
||||
createRule: null,
|
||||
updateRule: null,
|
||||
deleteRule: null
|
||||
};
|
||||
|
||||
// Step 2: Open only what's needed with proper checks
|
||||
const collection = {
|
||||
name: 'user_settings',
|
||||
// Users can only see their own settings
|
||||
listRule: 'user = @request.auth.id',
|
||||
viewRule: 'user = @request.auth.id',
|
||||
// Users can only create settings for themselves
|
||||
createRule: '@request.auth.id != "" && @request.body.user = @request.auth.id',
|
||||
// Users can only update their own settings
|
||||
updateRule: 'user = @request.auth.id',
|
||||
// Prevent deletion or restrict to owner
|
||||
deleteRule: 'user = @request.auth.id'
|
||||
};
|
||||
|
||||
// For truly public data, document why it's open
|
||||
const collection = {
|
||||
name: 'public_announcements',
|
||||
// Intentionally public - these are site-wide announcements
|
||||
listRule: '',
|
||||
viewRule: '',
|
||||
// Only admins can manage (using custom "role" field on auth collection)
|
||||
// IMPORTANT: Prevent role self-assignment in the users collection updateRule:
|
||||
// updateRule: 'id = @request.auth.id && @request.body.role:isset = false'
|
||||
createRule: '@request.auth.role = "admin"',
|
||||
updateRule: '@request.auth.role = "admin"',
|
||||
deleteRule: '@request.auth.role = "admin"'
|
||||
};
|
||||
```
|
||||
|
||||
**Rule development workflow:**
|
||||
|
||||
1. **Start locked** - All rules `null`
|
||||
2. **Identify access needs** - Who needs what access?
|
||||
3. **Write minimal rules** - Open only required operations
|
||||
4. **Test thoroughly** - Verify both allowed and denied cases
|
||||
5. **Document decisions** - Comment why rules are set as they are
|
||||
|
||||
**Security checklist:**
|
||||
- [ ] No empty string rules without justification
|
||||
- [ ] Ownership checks on personal data
|
||||
- [ ] Auth checks on write operations
|
||||
- [ ] Admin-only rules for sensitive operations
|
||||
- [ ] Tested with different user contexts
|
||||
|
||||
Reference: [PocketBase API Rules](https://pocketbase.io/docs/api-rules-and-filters/)
|
||||
|
||||
## 5. Use @request Context in API Rules
|
||||
|
||||
**Impact: CRITICAL (Enables dynamic, user-aware access control)**
|
||||
|
||||
The `@request` object provides access to the current request context including authenticated user, request body, query parameters, and headers. Use it to build dynamic access rules.
|
||||
|
||||
**Incorrect (hardcoded or missing auth checks):**
|
||||
|
||||
```javascript
|
||||
// No authentication check
|
||||
const collection = {
|
||||
listRule: '', // Anyone can see everything
|
||||
createRule: '' // Anyone can create
|
||||
};
|
||||
|
||||
// Hardcoded user ID (never do this)
|
||||
const collection = {
|
||||
listRule: 'owner = "specific_user_id"' // Only one user can access
|
||||
};
|
||||
```
|
||||
|
||||
**Correct (using @request context):**
|
||||
|
||||
```javascript
|
||||
// Check if user is authenticated
|
||||
createRule: '@request.auth.id != ""'
|
||||
|
||||
// Check ownership via auth record
|
||||
listRule: 'owner = @request.auth.id'
|
||||
viewRule: 'owner = @request.auth.id'
|
||||
updateRule: 'owner = @request.auth.id'
|
||||
deleteRule: 'owner = @request.auth.id'
|
||||
|
||||
// Access auth record fields
|
||||
// IMPORTANT: If using custom role fields, ensure update rules prevent
|
||||
// users from modifying their own role: @request.body.role:isset = false
|
||||
listRule: '@request.auth.role = "admin"'
|
||||
listRule: '@request.auth.verified = true'
|
||||
|
||||
// Validate request body on create/update
|
||||
createRule: '@request.auth.id != "" && @request.body.owner = @request.auth.id'
|
||||
|
||||
// Prevent changing certain fields
|
||||
updateRule: 'owner = @request.auth.id && @request.body.owner:isset = false'
|
||||
|
||||
// WARNING: Query parameters are user-controlled and should NOT be used
|
||||
// for authorization decisions. Use them only for optional filtering behavior
|
||||
// where the fallback is equally safe.
|
||||
// listRule: '@request.query.publicOnly = "true" || owner = @request.auth.id'
|
||||
// The above is UNSAFE - users can bypass ownership by adding ?publicOnly=true
|
||||
// Instead, use separate endpoints or server-side logic for public vs. private views.
|
||||
listRule: 'owner = @request.auth.id || public = true' // Use a record field, not query param
|
||||
|
||||
// Access nested auth relations
|
||||
listRule: 'team.members ?= @request.auth.id'
|
||||
```
|
||||
|
||||
**Available @request fields:**
|
||||
|
||||
| Field | Description |
|
||||
|-------|-------------|
|
||||
| `@request.auth.id` | Authenticated user's ID (empty string if not authenticated) |
|
||||
| `@request.auth.*` | Any field from auth record (role, verified, email, etc.) |
|
||||
| `@request.body.*` | Request body fields (create/update only) |
|
||||
| `@request.query.*` | URL query parameters |
|
||||
| `@request.headers.*` | Request headers |
|
||||
| `@request.method` | HTTP method (GET, POST, etc.) |
|
||||
| `@request.context` | Request context: `default`, `oauth2`, `otp`, `password`, `realtime`, `protectedFile` |
|
||||
|
||||
**Body field modifiers:**
|
||||
|
||||
```javascript
|
||||
// Check if field is being set
|
||||
updateRule: '@request.body.status:isset = false' // Can't change status
|
||||
|
||||
// Check if field changed from current value
|
||||
updateRule: '@request.body.owner:changed = false' // Can't change owner
|
||||
|
||||
// Get length of array/string
|
||||
createRule: '@request.body.tags:length <= 5' // Max 5 tags
|
||||
```

## 6. Use strftime() for Date Arithmetic in Filter Expressions
|

|

**Impact: MEDIUM (strftime() (added in v0.36) replaces brittle string prefix comparisons on datetime fields)**
|
||||
|
||||
PocketBase v0.36 added the `strftime()` function to the filter expression grammar. It maps directly to SQLite's [strftime](https://sqlite.org/lang_datefunc.html) and is the correct way to bucket, compare, or extract parts of a datetime field. Before v0.36 people worked around this with `~` (substring) matches against the ISO string; those workarounds are fragile (they break at midnight UTC, ignore timezones, and can't handle ranges).
|
||||
|
||||
**Incorrect (substring match on the ISO datetime string):**
|
||||
|
||||
```javascript
|
||||
// ❌ "matches anything whose ISO string contains 2026-04-08" - breaks as soon
|
||||
// as your DB stores sub-second precision or you cross a month boundary
|
||||
const todayPrefix = new Date().toISOString().slice(0, 10);
|
||||
const results = await pb.collection("orders").getList(1, 50, {
|
||||
filter: `created ~ "${todayPrefix}"`, // ❌
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (strftime with named format specifiers):**
|
||||
|
||||
```javascript
|
||||
// "all orders created today (UTC)"
|
||||
const results = await pb.collection("orders").getList(1, 50, {
|
||||
filter: `strftime('%Y-%m-%d', created) = strftime('%Y-%m-%d', @now)`,
|
||||
});
|
||||
|
||||
// "all orders from March 2026"
|
||||
await pb.collection("orders").getList(1, 50, {
|
||||
filter: `strftime('%Y-%m', created) = "2026-03"`,
|
||||
});
|
||||
|
||||
// "orders created this hour"
|
||||
await pb.collection("orders").getList(1, 50, {
|
||||
filter: `strftime('%Y-%m-%d %H', created) = strftime('%Y-%m-%d %H', @now)`,
|
||||
});
|
||||
```
|
||||
|
||||
```javascript
|
||||
// Same function is available inside API rules:
|
||||
// collection "orders" - List rule:
|
||||
// @request.auth.id != "" &&
|
||||
// user = @request.auth.id &&
|
||||
// strftime('%Y-%m-%d', created) = strftime('%Y-%m-%d', @now)
|
||||
```
|
||||
|
||||
**Common format specifiers:**
|
||||
|
||||
| Specifier | Meaning |
|
||||
|---|---|
|
||||
| `%Y` | 4-digit year |
|
||||
| `%m` | month (01-12) |
|
||||
| `%d` | day of month (01-31) |
|
||||
| `%H` | hour (00-23) |
|
||||
| `%M` | minute (00-59) |
|
||||
| `%S` | second (00-59) |
|
||||
| `%W` | ISO week (00-53) |
|
||||
| `%j` | day of year (001-366) |
|
||||
| `%w` | day of week (0=Sunday) |
|
||||
|
||||
**Other filter functions worth knowing:**
|
||||
|
||||
| Function | Use |
|
||||
|---|---|
|
||||
| `strftime(fmt, datetime)` | Format/extract datetime parts (v0.36+) |
|
||||
| `length(field)` | Count elements in a multi-value field (file, relation, select) |
|
||||
| `each(field, expr)` | Iterate over multi-value fields: `each(tags, ? ~ "urgent")` |
|
||||
| `issetIf(field, val)` | Conditional presence check used in complex rules |

# Authentication
|
||||
|
||||
**Impact: CRITICAL**
|
||||
|
||||
Password authentication, OAuth2 integration, token management, MFA setup, and auth collection configuration.
|
||||
|
||||
---
|
||||
|
||||
## 1. Use Impersonation for Admin Operations
|
||||
|
||||
**Impact: MEDIUM (Safe admin access to user data without password sharing)**
|
||||
|
||||
Impersonation allows superusers to generate tokens for other users, enabling admin support tasks and API key functionality without sharing passwords.
|
||||
|
||||
**Incorrect (sharing credentials or bypassing auth):**
|
||||
|
||||
```javascript
|
||||
// Bad: sharing user passwords for support
|
||||
async function helpUser(userId, userPassword) {
|
||||
await pb.collection('users').authWithPassword(userEmail, userPassword);
|
||||
// Support team knows user's password!
|
||||
}
|
||||
|
||||
// Bad: directly modifying records without proper context
|
||||
async function fixUserData(userId) {
|
||||
// Bypasses user's perspective and rules
|
||||
await pb.collection('posts').update(postId, { fixed: true });
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using impersonation):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
// Admin client with superuser auth (use environment variables, never hardcode)
|
||||
const adminPb = new PocketBase(process.env.PB_URL);
|
||||
await adminPb.collection('_superusers').authWithPassword(
|
||||
process.env.PB_SUPERUSER_EMAIL,
|
||||
process.env.PB_SUPERUSER_PASSWORD
|
||||
);
|
||||
|
||||
async function impersonateUser(userId) {
|
||||
// Generate impersonation token (non-renewable)
|
||||
const impersonatedClient = await adminPb
|
||||
.collection('users')
|
||||
.impersonate(userId, 3600); // 1 hour duration
|
||||
|
||||
// impersonatedClient has user's auth context
|
||||
console.log('Acting as:', impersonatedClient.authStore.record.email);
|
||||
|
||||
// Operations use user's permissions
|
||||
const userPosts = await impersonatedClient.collection('posts').getList();
|
||||
|
||||
return impersonatedClient;
|
||||
}
|
||||
|
||||
// Use case: Admin viewing user's data
|
||||
async function adminViewUserPosts(userId) {
|
||||
const userClient = await impersonateUser(userId);
|
||||
|
||||
// See exactly what the user sees (respects API rules)
|
||||
const posts = await userClient.collection('posts').getList();
|
||||
|
||||
return posts;
|
||||
}
|
||||
|
||||
// Use case: API keys for server-to-server communication
|
||||
async function createApiKey(serviceUserId) {
|
||||
// Create a service impersonation token (use short durations, rotate regularly)
|
||||
const serviceClient = await adminPb
|
||||
.collection('service_accounts')
|
||||
.impersonate(serviceUserId, 86400); // 24 hours max, rotate via scheduled task
|
||||
|
||||
// Return token for service to use
|
||||
return serviceClient.authStore.token;
|
||||
}
|
||||
|
||||
// Using API key token in another service
|
||||
async function useApiKey(apiToken) {
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Manually set the token
|
||||
pb.authStore.save(apiToken, null);
|
||||
|
||||
// Now requests use the service account's permissions
|
||||
const data = await pb.collection('data').getList();
|
||||
return data;
|
||||
}
|
||||
```
|
||||
|
||||
**Important considerations:**
|
||||
|
||||
```javascript
|
||||
// Impersonation tokens are non-renewable
|
||||
const client = await adminPb.collection('users').impersonate(userId, 3600);
|
||||
|
||||
// This will fail - can't refresh impersonation tokens
|
||||
try {
|
||||
await client.collection('users').authRefresh();
|
||||
} catch (error) {
|
||||
// Expected: impersonation tokens can't be refreshed
|
||||
}
|
||||
|
||||
// For continuous access, generate new token when needed
|
||||
async function getImpersonatedClient(userId) {
|
||||
// Check if existing token is still valid
|
||||
if (cachedClient?.authStore.isValid) {
|
||||
return cachedClient;
|
||||
}
|
||||
|
||||
// Generate fresh token
|
||||
return await adminPb.collection('users').impersonate(userId, 3600);
|
||||
}
|
||||
```
|
||||
|
||||
**Security best practices:**
|
||||
- Use short durations for support tasks
|
||||
- Log all impersonation events
|
||||
- Restrict impersonation to specific admin roles
|
||||
- Never expose impersonation capability in client code
|
||||
- Use dedicated service accounts for API keys

|
||||
|
||||
## 2. Implement Multi-Factor Authentication
|
||||
|
||||
**Impact: HIGH (Additional security layer for sensitive applications)**
|
||||
|
||||
MFA requires users to authenticate with two different methods. PocketBase supports OTP (One-Time Password) via email as the second factor.
|
||||
|
||||
**Incorrect (single-factor only for sensitive apps):**
|
||||
|
||||
```javascript
|
||||
// Insufficient for sensitive applications
|
||||
async function login(email, password) {
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
// User immediately has full access - no second factor
|
||||
return authData;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (MFA flow with OTP):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
async function loginWithMFA(email, password) {
|
||||
try {
|
||||
// First factor: password
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
|
||||
// If MFA not required, auth succeeds immediately
|
||||
return { success: true, authData };
|
||||
|
||||
} catch (error) {
|
||||
// MFA required - returns 401 with mfaId
|
||||
if (error.status === 401 && error.response?.mfaId) {
|
||||
return {
|
||||
success: false,
|
||||
mfaRequired: true,
|
||||
mfaId: error.response.mfaId
|
||||
};
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
async function requestOTP(email) {
|
||||
// Request OTP to be sent via email
|
||||
const result = await pb.collection('users').requestOTP(email);
|
||||
|
||||
// Returns otpId - needed to verify the OTP
|
||||
// Note: Returns otpId even if email doesn't exist (prevents enumeration)
|
||||
return result.otpId;
|
||||
}
|
||||
|
||||
async function completeMFAWithOTP(mfaId, otpId, otpCode) {
|
||||
try {
|
||||
// Second factor: OTP verification
|
||||
const authData = await pb.collection('users').authWithOTP(
|
||||
otpId,
|
||||
otpCode,
|
||||
{ mfaId } // Include mfaId from first factor
|
||||
);
|
||||
|
||||
return { success: true, authData };
|
||||
} catch (error) {
|
||||
if (error.status === 400) {
|
||||
throw new Error('Invalid or expired code');
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Complete flow example
|
||||
async function fullMFAFlow(email, password, otpCode = null) {
|
||||
// Step 1: Password authentication
|
||||
const step1 = await loginWithMFA(email, password);
|
||||
|
||||
if (step1.success) {
|
||||
return step1.authData; // MFA not required
|
||||
}
|
||||
|
||||
if (step1.mfaRequired) {
|
||||
// Step 2: Request OTP
|
||||
const otpId = await requestOTP(email);
|
||||
|
||||
// Step 3: UI prompts user for OTP code...
|
||||
// (In real app, wait for user input)
|
||||
|
||||
if (otpCode) {
|
||||
// Step 4: Complete MFA
|
||||
const step2 = await completeMFAWithOTP(step1.mfaId, otpId, otpCode);
|
||||
return step2.authData;
|
||||
}
|
||||
|
||||
return { pendingMFA: true, mfaId: step1.mfaId, otpId };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Configure MFA (Admin UI or API):**
|
||||
|
||||
```javascript
|
||||
// Enable MFA on auth collection (superuser only)
|
||||
await pb.collections.update('users', {
|
||||
mfa: {
|
||||
enabled: true,
|
||||
duration: 1800, // MFA session duration (30 min)
|
||||
rule: '' // When to require MFA (empty = always for all users)
|
||||
// rule: '@request.auth.role = "admin"' // Only for admins
|
||||
},
|
||||
otp: {
|
||||
enabled: true,
|
||||
duration: 300, // OTP validity (5 min)
|
||||
length: 6, // OTP code length
|
||||
emailTemplate: {
|
||||
subject: 'Your verification code',
|
||||
body: 'Your code is: {OTP}'
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**MFA best practices:**
|
||||
- Always enable for admin accounts
|
||||
- Consider making MFA optional for regular users
|
||||
- Use short OTP durations (5-10 minutes)
|
||||
- Implement rate limiting on OTP requests
|
||||
- Log MFA events for security auditing

|
||||
|
||||
## 3. Integrate OAuth2 Providers Correctly
|
||||
|
||||
**Impact: CRITICAL (Secure third-party authentication with proper flow handling)**
|
||||
|
||||
OAuth2 integration should use the all-in-one method for simplicity and security. Manual code exchange should only be used when necessary (e.g., mobile apps with deep links).
|
||||
|
||||
**Incorrect (manual implementation without SDK):**
|
||||
|
||||
```javascript
|
||||
// Don't manually handle OAuth flow
|
||||
async function loginWithGoogle() {
|
||||
// Redirect user to Google manually
|
||||
window.location.href = 'https://accounts.google.com/oauth/authorize?...';
|
||||
}
|
||||
|
||||
// Manual callback handling
|
||||
async function handleCallback(code) {
|
||||
// Exchange code manually - error prone!
|
||||
const response = await fetch('/api/auth/callback', {
|
||||
method: 'POST',
|
||||
body: JSON.stringify({ code })
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using SDK's all-in-one method):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// All-in-one OAuth2 (recommended for web apps)
|
||||
async function loginWithOAuth2(providerName) {
|
||||
try {
|
||||
const authData = await pb.collection('users').authWithOAuth2({
|
||||
provider: providerName, // 'google', 'github', 'microsoft', etc.
|
||||
// Optional: create new user data if not exists
|
||||
createData: {
|
||||
emailVisibility: true,
|
||||
name: '' // Will be populated from OAuth provider
|
||||
}
|
||||
});
|
||||
|
||||
console.log('Logged in via', providerName);
|
||||
console.log('User:', authData.record.email);
|
||||
console.log('Is new user:', authData.meta?.isNew);
|
||||
|
||||
return authData;
|
||||
} catch (error) {
|
||||
if (error.isAbort) {
|
||||
console.log('OAuth popup was closed');
|
||||
return null;
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
document.getElementById('google-btn').onclick = () => loginWithOAuth2('google');
|
||||
document.getElementById('github-btn').onclick = () => loginWithOAuth2('github');
|
||||
```
|
||||
|
||||
**Manual code exchange (for React Native / deep links):**
|
||||
|
||||
```javascript
|
||||
// Only use when all-in-one isn't possible
|
||||
async function loginWithOAuth2Manual() {
|
||||
// Get auth methods - PocketBase provides state and codeVerifier
|
||||
const authMethods = await pb.collection('users').listAuthMethods();
|
||||
const provider = authMethods.oauth2.providers.find(p => p.name === 'google');
|
||||
|
||||
// Store the provider's state and codeVerifier for callback verification
|
||||
// PocketBase generates these for you - don't create your own
|
||||
sessionStorage.setItem('oauth_state', provider.state);
|
||||
sessionStorage.setItem('oauth_code_verifier', provider.codeVerifier);
|
||||
|
||||
// Build the OAuth URL using provider.authURL + redirect
|
||||
const redirectUrl = window.location.origin + '/oauth-callback';
|
||||
const authUrl = provider.authURL + encodeURIComponent(redirectUrl);
|
||||
|
||||
// Redirect to OAuth provider
|
||||
window.location.href = authUrl;
|
||||
}
|
||||
|
||||
// In your callback handler (e.g., /oauth-callback page):
|
||||
async function handleOAuth2Callback() {
|
||||
const params = new URLSearchParams(window.location.search);
|
||||
|
||||
// CSRF protection: verify state matches
|
||||
if (params.get('state') !== sessionStorage.getItem('oauth_state')) {
|
||||
throw new Error('State mismatch - potential CSRF attack');
|
||||
}
|
||||
|
||||
const code = params.get('code');
|
||||
const codeVerifier = sessionStorage.getItem('oauth_code_verifier');
|
||||
const redirectUrl = window.location.origin + '/oauth-callback';
|
||||
|
||||
// Exchange code for auth token
|
||||
const authData = await pb.collection('users').authWithOAuth2Code(
|
||||
'google',
|
||||
code,
|
||||
codeVerifier,
|
||||
redirectUrl,
|
||||
{ emailVisibility: true }
|
||||
);
|
||||
|
||||
// Clean up
|
||||
sessionStorage.removeItem('oauth_state');
|
||||
sessionStorage.removeItem('oauth_code_verifier');
|
||||
|
||||
return authData;
|
||||
}
|
||||
```
|
||||
|
||||
**Configure OAuth2 provider (Admin UI or API):**
|
||||
|
||||
```javascript
|
||||
// Via API (superuser only) - usually done in Admin UI
|
||||
// IMPORTANT: Never hardcode client secrets. Use environment variables.
|
||||
await pb.collections.update('users', {
|
||||
oauth2: {
|
||||
enabled: true,
|
||||
providers: [{
|
||||
name: 'google',
|
||||
clientId: process.env.GOOGLE_CLIENT_ID,
|
||||
clientSecret: process.env.GOOGLE_CLIENT_SECRET
|
||||
}],
|
||||
mappedFields: {
|
||||
avatarURL: 'avatar' // Map OAuth field to collection field
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
Reference: [PocketBase OAuth2](https://pocketbase.io/docs/authentication/#oauth2-authentication)
|
||||
|
||||
## 4. Use authWithOTP for Email One-Time Codes, Rate-Limit requestOTP
|
||||
|
||||
**Impact: HIGH (OTP endpoints are unauthenticated; unthrottled requestOTP enables email bombing and enumeration)**
|
||||
|
||||
Auth collections can enable **OTP login** from the admin UI (Collection → Options → "Enable OTP"). The client flow is two steps: `requestOTP(email)` returns an `otpId`, then `authWithOTP(otpId, code)` exchanges the id + code for an auth token. Two things trip people up: (1) the OTP response is **the same whether the email exists or not** - do not break that by leaking a distinct error; (2) `requestOTP` sends an email, so **it must be rate-limited** or an attacker can use it to spam any address.
|
||||
|
||||
**Incorrect (leaks existence, custom requestOTP with no rate limit):**
|
||||
|
||||
```javascript
|
||||
// ❌ Client-side existence check - ignore the 404 and expose it to the user
|
||||
try {
|
||||
await pb.collection("users").getFirstListItem(`email="${email}"`);
|
||||
} catch (e) {
|
||||
alert("No account with that email"); // ❌ account enumeration
|
||||
return;
|
||||
}
|
||||
|
||||
// ❌ Ad-hoc route with no rate limit - attacker hammers this to spam mailboxes
|
||||
routerAdd("POST", "/api/myapp/otp", (e) => {
|
||||
const body = e.requestInfo().body;
|
||||
const user = $app.findAuthRecordByEmail("users", body.email);
|
||||
// send custom email...
|
||||
return e.json(200, { ok: true });
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (use the built-in flow, step 1 always returns an otpId):**
|
||||
|
||||
```javascript
|
||||
// Step 1: request the code. Always returns { otpId } - even if the email
|
||||
// does not exist, PocketBase returns a synthetic id so enumeration is
|
||||
// impossible. Treat every response as success from the UI perspective.
|
||||
const { otpId } = await pb.collection("users").requestOTP("user@example.com");
|
||||
|
||||
// Step 2: exchange otpId + the 8-digit code the user typed
|
||||
const authData = await pb.collection("users").authWithOTP(
|
||||
otpId,
|
||||
"12345678",
|
||||
);
|
||||
// pb.authStore is now populated
|
||||
```
|
||||
|
||||
```go
|
||||
// Go side - rate-limit and log if you wrap your own endpoint
|
||||
app.OnRecordRequestOTPRequest("users").BindFunc(func(e *core.RecordRequestOTPRequestEvent) error {
|
||||
// e.Collection, e.Record (may be nil - synthetic id path),
|
||||
// e.Email (always present), e.Password (unused for OTP)
|
||||
e.App.Logger().Info("otp requested",
|
||||
"email", e.Email,
|
||||
"ip", e.RequestInfo.Headers["x_forwarded_for"])
|
||||
return e.Next() // REQUIRED
|
||||
})
|
||||
```
|
||||
|
||||
**Rules:**
|
||||
- `requestOTP` **always returns 200 with an otpId**, even for non-existent emails - preserve that by never adding a pre-check or a different error path.
|
||||
- Enable the built-in rate limiter (see `deploy-rate-limiting.md`) and raise the cost for the `*:requestOTP` label. Without this, an attacker can email-bomb arbitrary users.
|
||||
- The OTP code is 8 digits by default, with a 3-minute TTL. Do not extend the TTL - short windows are the whole point.
|
||||
- `authWithOTP` consumes the code; a successful call invalidates the `otpId`. Always show a generic "invalid or expired code" on failure.
|
||||
- If you want OTP **without a password**, set the collection's `Password` option to off and `OTP` on. If both are enabled, users can use either.
|
||||
- OTP emails are sent via the configured SMTP server. In dev, point SMTP at Mailpit or a console logger before testing - do **not** ship with the default "no-reply@example.com" sender.

## 5. Implement Secure Password Authentication
|
||||
|
||||
**Impact: CRITICAL (Secure user login with proper error handling and token management)**
|
||||
|
||||
Password authentication should include proper error handling, avoid exposing whether emails exist, and correctly manage the auth store.
|
||||
|
||||
**Incorrect (exposing information and poor error handling):**
|
||||
|
||||
```javascript
|
||||
// Dangerous: exposes whether email exists
|
||||
async function login(email, password) {
|
||||
const user = await pb.collection('users').getFirstListItem(`email = "${email}"`);
|
||||
if (!user) {
|
||||
throw new Error('Email not found'); // Reveals email doesn't exist
|
||||
}
|
||||
|
||||
// Manual password check - never do this!
|
||||
if (user.password !== password) {
|
||||
throw new Error('Wrong password'); // Reveals password is wrong
|
||||
}
|
||||
|
||||
return user;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (secure authentication):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
async function login(email, password) {
|
||||
try {
|
||||
// authWithPassword handles hashing and returns token
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
|
||||
// Token is automatically stored in pb.authStore
|
||||
console.log('Logged in as:', authData.record.email);
|
||||
console.log('Token valid:', pb.authStore.isValid);
|
||||
|
||||
return authData;
|
||||
} catch (error) {
|
||||
// Generic error message - don't reveal if email exists
|
||||
if (error.status === 400) {
|
||||
throw new Error('Invalid email or password');
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Check if user is authenticated
|
||||
function isAuthenticated() {
|
||||
return pb.authStore.isValid;
|
||||
}
|
||||
|
||||
// Get current user
|
||||
function getCurrentUser() {
|
||||
return pb.authStore.record;
|
||||
}
|
||||
|
||||
// Logout
|
||||
function logout() {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
|
||||
// Listen for auth changes
|
||||
pb.authStore.onChange((token, record) => {
|
||||
console.log('Auth state changed:', record?.email || 'logged out');
|
||||
}, true); // true = fire immediately with current state
|
||||
```
|
||||
|
||||
**Auth collection configuration for password auth:**
|
||||
|
||||
```javascript
|
||||
// When creating auth collection via API (superuser only)
|
||||
await pb.collections.create({
|
||||
name: 'users',
|
||||
type: 'auth',
|
||||
fields: [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'avatar', type: 'file', options: { maxSelect: 1 } }
|
||||
],
|
||||
passwordAuth: {
|
||||
enabled: true,
|
||||
identityFields: ['email', 'username'] // Fields that can be used to login
|
||||
},
|
||||
// Require minimum password length
|
||||
// (configured in Admin UI under collection options)
|
||||
});
|
||||
```
|
||||
|
||||
**Security considerations:**
|
||||
- Never store passwords in plain text
|
||||
- Use generic error messages
|
||||
- Implement rate limiting on your server
|
||||
- Consider adding MFA for sensitive applications
|
||||

||||

|
||||
|
||||
## 6. Manage Auth Tokens Properly
|
||||
|
||||
**Impact: CRITICAL (Prevents unauthorized access, handles token expiration gracefully)**
|
||||
|
||||
Auth tokens should be refreshed before expiration, validated on critical operations, and properly cleared on logout. The SDK's authStore handles most of this automatically.
|
||||
|
||||
**Incorrect (ignoring token expiration):**
|
||||
|
||||
```javascript
|
||||
// Bad: never checking token validity
|
||||
async function fetchUserData() {
|
||||
// Token might be expired!
|
||||
const records = await pb.collection('posts').getList();
|
||||
return records;
|
||||
}
|
||||
|
||||
// Bad: manually managing tokens
|
||||
let authToken = localStorage.getItem('token');
|
||||
fetch('/api/posts', {
|
||||
headers: { 'Authorization': authToken } // Token might be invalid
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (proper token management):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Check token validity before operations
|
||||
async function fetchSecureData() {
|
||||
// authStore.isValid is a client-side check only (JWT expiry parsing).
|
||||
// Always verify server-side with authRefresh() for critical operations.
|
||||
if (!pb.authStore.isValid) {
|
||||
throw new Error('Please log in');
|
||||
}
|
||||
|
||||
return pb.collection('posts').getList();
|
||||
}
|
||||
|
||||
// Refresh token periodically or before expiration
|
||||
async function refreshAuthIfNeeded() {
|
||||
if (!pb.authStore.isValid) {
|
||||
return false;
|
||||
}
|
||||
|
||||
try {
|
||||
// Verifies current token and returns fresh one
|
||||
await pb.collection('users').authRefresh();
|
||||
console.log('Token refreshed');
|
||||
return true;
|
||||
} catch (error) {
|
||||
// Token invalid - user needs to re-authenticate
|
||||
pb.authStore.clear();
|
||||
return false;
|
||||
}
|
||||
}
|
||||
|
||||
// Auto-refresh on app initialization
|
||||
async function initializeAuth() {
|
||||
if (pb.authStore.token) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Listen for auth changes and handle expiration
|
||||
pb.authStore.onChange((token, record) => {
|
||||
if (!token) {
|
||||
// User logged out or token cleared
|
||||
redirectToLogin();
|
||||
}
|
||||
});
|
||||
|
||||
// Setup periodic refresh (e.g., every 10 minutes)
|
||||
setInterval(async () => {
|
||||
if (pb.authStore.isValid) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
}, 10 * 60 * 1000);
|
||||
```
|
||||
|
||||
**SSR / Server-side token handling:**
|
||||
|
||||
```javascript
|
||||
// Server-side: create fresh client per request
|
||||
export async function handleRequest(request) {
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Load auth from cookie
|
||||
pb.authStore.loadFromCookie(request.headers.get('cookie') || '');
|
||||
|
||||
// Validate and refresh
|
||||
if (pb.authStore.isValid) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
|
||||
// ... handle request ...
|
||||
|
||||
// Send updated cookie with secure options
|
||||
const response = new Response();
|
||||
response.headers.set('set-cookie', pb.authStore.exportToCookie({
|
||||
httpOnly: true, // Prevent XSS access to auth token
|
||||
secure: true, // HTTPS only
|
||||
sameSite: 'Lax', // CSRF protection
|
||||
}));
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
**Token configuration (Admin UI or migration):**
|
||||
|
||||
```javascript
|
||||
// Configure token durations (superuser only)
|
||||
await pb.collections.update('users', {
|
||||
authToken: {
|
||||
duration: 1209600 // 14 days in seconds
|
||||
},
|
||||
verificationToken: {
|
||||
duration: 604800 // 7 days
|
||||
}
|
||||
});

# Collection Design
|
||||
|
||||
**Impact: CRITICAL**
|
||||
|
||||
Schema design, field types, relations, indexes, and collection type selection. Foundation for application architecture and long-term maintainability.
|
||||
|
||||
---
|
||||
|
||||
## 1. Use Auth Collections for User Accounts
|
||||
|
||||
**Impact: CRITICAL (Built-in authentication, password hashing, OAuth2 support)**
|
||||
|
||||
Auth collections provide built-in authentication features including secure password hashing, email verification, OAuth2 support, and token management. Using base collections for users requires reimplementing these security-critical features.
|
||||
|
||||
**Incorrect (using base collection for users):**
|
||||
|
||||
```javascript
|
||||
// Base collection loses all auth features
|
||||
const usersCollection = {
|
||||
name: 'users',
|
||||
type: 'base', // Wrong! No auth capabilities
|
||||
schema: [
|
||||
{ name: 'email', type: 'email' },
|
||||
{ name: 'password', type: 'text' }, // Stored in plain text!
|
||||
{ name: 'name', type: 'text' }
|
||||
]
|
||||
};
|
||||
|
||||
// Manual login implementation - insecure
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
`email = "${email}" && password = "${password}"` // SQL injection risk!
|
||||
);
|
||||
```
|
||||
|
||||
**Correct (using auth collection):**
|
||||
|
||||
```javascript
|
||||
// Auth collection with built-in security
|
||||
const usersCollection = {
|
||||
name: 'users',
|
||||
type: 'auth', // Enables authentication features
|
||||
schema: [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'avatar', type: 'file', options: { maxSelect: 1 } }
|
||||
],
|
||||
options: {
|
||||
allowEmailAuth: true,
|
||||
allowOAuth2Auth: true,
|
||||
requireEmail: true,
|
||||
minPasswordLength: 8
|
||||
}
|
||||
};
|
||||
|
||||
// Secure authentication with password hashing
|
||||
const authData = await pb.collection('users').authWithPassword(
|
||||
'user@example.com',
|
||||
'securePassword123'
|
||||
);
|
||||
|
||||
// Token automatically stored in authStore
|
||||
// NOTE: Never log tokens in production - shown here for illustration only
|
||||
console.log('Authenticated as:', pb.authStore.record.id);
|
||||
```
|
||||
|
||||
**When to use each type:**
|
||||
- **Auth collection**: User accounts, admin accounts, any entity that needs to log in
|
||||
- **Base collection**: Regular data like posts, products, orders, comments
|
||||
- **View collection**: Read-only aggregations or complex queries
|
||||
|
||||
Reference: [PocketBase Auth Collections](https://pocketbase.io/docs/collections/#auth-collection)
|
||||
|
||||
## 2. Choose Appropriate Field Types for Your Data
|
||||
|
||||
**Impact: CRITICAL (Prevents data corruption, improves query performance, reduces storage)**
|
||||
|
||||
Selecting the wrong field type leads to data validation issues, wasted storage, and poor query performance. PocketBase provides specialized field types that enforce constraints at the database level.
|
||||
|
||||
**Incorrect (using text for everything):**
|
||||
|
||||
```javascript
|
||||
// Using plain text fields for structured data
|
||||
const collection = {
|
||||
name: 'products',
|
||||
schema: [
|
||||
{ name: 'price', type: 'text' }, // Should be number
|
||||
{ name: 'email', type: 'text' }, // Should be email
|
||||
{ name: 'website', type: 'text' }, // Should be url
|
||||
{ name: 'active', type: 'text' }, // Should be bool
|
||||
{ name: 'tags', type: 'text' }, // Should be select or json
|
||||
{ name: 'created', type: 'text' } // Should be autodate
|
||||
]
|
||||
};
|
||||
// No validation, inconsistent data, manual parsing required
|
||||
```
|
||||
|
||||
**Correct (using appropriate field types):**
|
||||
|
||||
```javascript
|
||||
// Using specialized field types with proper validation
|
||||
const collection = {
|
||||
name: 'products',
|
||||
type: 'base',
|
||||
schema: [
|
||||
{ name: 'price', type: 'number', options: { min: 0 } },
|
||||
{ name: 'email', type: 'email' },
|
||||
{ name: 'website', type: 'url' },
|
||||
{ name: 'active', type: 'bool' },
|
||||
{ name: 'tags', type: 'select', options: {
|
||||
maxSelect: 5,
|
||||
values: ['electronics', 'clothing', 'food', 'other']
|
||||
}},
|
||||
{ name: 'metadata', type: 'json' }
|
||||
// created/updated are automatic system fields
|
||||
]
|
||||
};
|
||||
// Built-in validation, proper indexing, type-safe queries
|
||||
```
|
||||
|
||||
**Available field types:**
|
||||
- `text` - Plain text with optional min/max length, regex pattern
|
||||
- `number` - Integer or decimal with optional min/max
|
||||
- `bool` - True/false values
|
||||
- `email` - Email with format validation
|
||||
- `url` - URL with format validation
|
||||
- `date` - Date/datetime values
|
||||
- `autodate` - Auto-set on create/update
|
||||
- `select` - Single or multi-select from predefined values
|
||||
- `json` - Arbitrary JSON data
|
||||
- `file` - File attachments
|
||||
- `relation` - References to other collections
|
||||
- `editor` - Rich text HTML content
|
||||
|
||||
Reference: [PocketBase Collections](https://pocketbase.io/docs/collections/)
|
||||
|
||||
## 3. Use GeoPoint Fields for Location Data
|
||||
|
||||
**Impact: MEDIUM (Built-in geographic queries, distance calculations)**
|
||||
|
||||
PocketBase provides a dedicated GeoPoint field type for storing geographic coordinates with built-in distance query support via `geoDistance()`.
|
||||
|
||||
**Incorrect (storing coordinates as separate fields):**
|
||||
|
||||
```javascript
|
||||
// Separate lat/lon fields - no built-in distance queries
|
||||
const placesSchema = [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'latitude', type: 'number' },
|
||||
{ name: 'longitude', type: 'number' }
|
||||
];
|
||||
|
||||
// Manual distance calculation - complex and slow
|
||||
async function findNearby(lat, lon, maxKm) {
|
||||
const places = await pb.collection('places').getFullList();
|
||||
|
||||
// Calculate distance for every record client-side
|
||||
return places.filter(place => {
|
||||
const dist = haversine(lat, lon, place.latitude, place.longitude);
|
||||
return dist <= maxKm;
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using GeoPoint field):**
|
||||
|
||||
```javascript
|
||||
// GeoPoint field stores coordinates as { lon, lat } object
|
||||
const placesSchema = [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'location', type: 'geopoint' }
|
||||
];
|
||||
|
||||
// Creating a record with GeoPoint
|
||||
await pb.collection('places').create({
|
||||
name: 'Coffee Shop',
|
||||
location: { lon: -73.9857, lat: 40.7484 } // Note: lon first!
|
||||
});
|
||||
|
||||
// Or using "lon,lat" string format
|
||||
await pb.collection('places').create({
|
||||
name: 'Restaurant',
|
||||
location: '-73.9857,40.7484' // String format also works
|
||||
});
|
||||
|
||||
// Query nearby locations using geoDistance()
|
||||
async function findNearby(lon, lat, maxKm) {
|
||||
// geoDistance returns distance in kilometers
|
||||
const places = await pb.collection('places').getList(1, 50, {
|
||||
filter: pb.filter(
|
||||
'geoDistance(location, {:point}) <= {:maxKm}',
|
||||
{
|
||||
point: { lon, lat },
|
||||
maxKm: maxKm
|
||||
}
|
||||
),
|
||||
sort: pb.filter('geoDistance(location, {:point})', { point: { lon, lat } })
|
||||
});
|
||||
|
||||
return places;
|
||||
}
|
||||
|
||||
// Find places within 5km of Times Square
|
||||
const nearbyPlaces = await findNearby(-73.9857, 40.7580, 5);
|
||||
|
||||
// Use in API rules for location-based access
|
||||
// listRule: geoDistance(location, @request.query.point) <= 10
|
||||
```
|
||||
|
||||
**geoDistance() function:**
|
||||
|
||||
```javascript
|
||||
// Syntax: geoDistance(geopointField, referencePoint)
|
||||
// Returns: distance in kilometers
|
||||
|
||||
// In filter expressions
|
||||
filter: 'geoDistance(location, "-73.9857,40.7484") <= 5'
|
||||
|
||||
// With parameter binding (recommended)
|
||||
filter: pb.filter('geoDistance(location, {:center}) <= {:radius}', {
|
||||
center: { lon: -73.9857, lat: 40.7484 },
|
||||
radius: 5
|
||||
})
|
||||
|
||||
// Sorting by distance
|
||||
sort: 'geoDistance(location, "-73.9857,40.7484")' // Closest first
|
||||
sort: '-geoDistance(location, "-73.9857,40.7484")' // Farthest first
|
||||
```
|
||||
|
||||
**GeoPoint data format:**
|
||||
|
||||
```javascript
|
||||
// Object format (recommended)
|
||||
{ lon: -73.9857, lat: 40.7484 }
|
||||
|
||||
// String format
|
||||
"-73.9857,40.7484" // "lon,lat" order
|
||||
|
||||
// Important: longitude comes FIRST (GeoJSON convention)
|
||||
```
|
||||
|
||||
**Use cases:**
|
||||
- Store-locator / find nearby
|
||||
- Delivery radius validation
|
||||
- Geofencing in API rules
|
||||
- Location-based search results
|
||||
|
||||
**Limitations:**
|
||||
- Spherical Earth calculation (accurate to ~0.3%)
|
||||
- No polygon/area containment queries
|
||||
- Single point per field (use multiple fields for routes)
|
||||

|
||||
## 4. Create Indexes for Frequently Filtered Fields
|
||||
|
||||
**Impact: CRITICAL (10-100x faster queries on large collections)**
|
||||
|
||||
PocketBase uses SQLite which benefits significantly from proper indexing. Queries filtering or sorting on unindexed fields perform full table scans.
|
||||
|
||||
**Incorrect (no indexes on filtered fields):**
|
||||
|
||||
```javascript
|
||||
// Querying without indexes
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'author = "user123" && status = "published"',
|
||||
sort: '-publishedAt'
|
||||
});
|
||||
// Full table scan on large collections - very slow
|
||||
|
||||
// API rules also query without indexes
|
||||
// listRule: "author = @request.auth.id"
|
||||
// Every list request scans entire table
|
||||
```
|
||||
|
||||
**Correct (indexed fields):**
|
||||
|
||||
```javascript
|
||||
// Create collection with indexes via Admin UI or migration
|
||||
// In PocketBase Admin: Collection > Indexes > Add Index
|
||||
|
||||
// Common index patterns:
|
||||
// 1. Single field index for equality filters
|
||||
// CREATE INDEX idx_posts_author ON posts(author)
|
||||
|
||||
// 2. Composite index for multiple filters
|
||||
// CREATE INDEX idx_posts_author_status ON posts(author, status)
|
||||
|
||||
// 3. Index with sort field
|
||||
// CREATE INDEX idx_posts_status_published ON posts(status, publishedAt DESC)
|
||||
|
||||
// Queries now use indexes
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'author = "user123" && status = "published"',
|
||||
sort: '-publishedAt'
|
||||
});
|
||||
// Index scan - fast even with millions of records
|
||||
|
||||
// For unique constraints (e.g., slug)
|
||||
// CREATE UNIQUE INDEX idx_posts_slug ON posts(slug)
|
||||
```
|
||||
|
||||
**Index recommendations:**
|
||||
- Fields used in `filter` expressions
|
||||
- Fields used in `sort` parameters
|
||||
- Fields used in API rules (`listRule`, `viewRule`, etc.)
|
||||
- Relation fields (automatically indexed)
|
||||
- Unique fields like slugs or codes
|
||||
|
||||
**Index considerations for SQLite:**
|
||||
- Composite indexes work left-to-right (order matters)
|
||||
- Too many indexes slow down writes
|
||||
- Use `EXPLAIN QUERY PLAN` in SQL to verify index usage
|
||||
- Partial indexes for filtered subsets
|
||||
|
||||
```sql
|
||||
-- Check if index is used
|
||||
EXPLAIN QUERY PLAN
|
||||
SELECT * FROM posts WHERE author = 'user123' AND status = 'published';
|
||||
-- Should show "USING INDEX" not "SCAN"
|
||||
```

||||
## 5. Configure Relations with Proper Cascade Options
|
||||
|
||||
**Impact: CRITICAL (Maintains referential integrity, prevents orphaned records, controls deletion behavior)**
|
||||
|
||||
Relation fields connect collections together. Proper cascade configuration ensures data integrity when referenced records are deleted.
|
||||
|
||||
**Incorrect (default cascade behavior not considered):**
|
||||
|
||||
```javascript
|
||||
// Relation without considering deletion behavior
|
||||
const ordersSchema = [
|
||||
{ name: 'customer', type: 'relation', options: {
|
||||
collectionId: 'customers_collection_id',
|
||||
maxSelect: 1
|
||||
// No cascade options specified - defaults may cause issues
|
||||
}},
|
||||
{ name: 'products', type: 'relation', options: {
|
||||
collectionId: 'products_collection_id'
|
||||
// Multiple products, no cascade handling
|
||||
}}
|
||||
];
|
||||
|
||||
// Deleting a customer may fail or orphan orders
|
||||
await pb.collection('customers').delete(customerId);
|
||||
// Error: record is referenced by other records
|
||||
```
|
||||
|
||||
**Correct (explicit cascade configuration):**
|
||||
|
||||
```javascript
|
||||
// Carefully configured relations
|
||||
const ordersSchema = [
|
||||
{
|
||||
name: 'customer',
|
||||
type: 'relation',
|
||||
required: true,
|
||||
options: {
|
||||
collectionId: 'customers_collection_id',
|
||||
maxSelect: 1,
|
||||
cascadeDelete: false // Prevent accidental mass deletion
|
||||
}
|
||||
},
|
||||
{
|
||||
name: 'products',
|
||||
type: 'relation',
|
||||
options: {
|
||||
collectionId: 'products_collection_id',
|
||||
maxSelect: 99,
|
||||
cascadeDelete: false
|
||||
}
|
||||
}
|
||||
];
|
||||
|
||||
// For dependent data like comments - cascade delete makes sense
|
||||
const commentsSchema = [
|
||||
{
|
||||
name: 'post',
|
||||
type: 'relation',
|
||||
options: {
|
||||
collectionId: 'posts_collection_id',
|
||||
maxSelect: 1,
|
||||
cascadeDelete: true // Delete comments when post is deleted
|
||||
}
|
||||
}
|
||||
];
|
||||
// NOTE: For audit logs, avoid cascadeDelete - logs should be retained
|
||||
// for compliance/forensics even after the referenced user is deleted.
|
||||
// Use cascadeDelete: false and handle user deletion separately.
|
||||
|
||||
// Handle deletion manually when cascade is false
|
||||
try {
|
||||
await pb.collection('customers').delete(customerId);
|
||||
} catch (e) {
|
||||
if (e.status === 400) {
|
||||
// Customer has orders - handle appropriately
|
||||
// Option 1: Soft delete (set 'deleted' flag)
|
||||
// Option 2: Reassign orders
|
||||
// Option 3: Delete orders first
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Cascade options:**
|
||||
- `cascadeDelete: true` - Delete referencing records when referenced record is deleted
|
||||
- `cascadeDelete: false` - Block deletion if references exist (default for required relations)
|
||||
|
||||
**Best practices:**
|
||||
- Use `cascadeDelete: true` for dependent data (comments on posts, logs for users)
|
||||
- Use `cascadeDelete: false` for important data (orders, transactions)
|
||||
- Consider soft deletes for audit trails
|
||||
- Document your cascade strategy
|
||||

|
||||
|
||||
## 6. Use View Collections for Complex Read-Only Queries
|
||||
|
||||
**Impact: HIGH (Simplifies complex queries, improves maintainability, enables aggregations)**
|
||||
|
||||
View collections execute custom SQL queries and expose results through the standard API. They're ideal for aggregations, joins, and computed fields without duplicating logic across your application.
|
||||
|
||||
**Incorrect (computing aggregations client-side):**
|
||||
|
||||
```javascript
|
||||
// Fetching all records to compute stats client-side
|
||||
const orders = await pb.collection('orders').getFullList();
|
||||
const products = await pb.collection('products').getFullList();
|
||||
|
||||
// Expensive client-side computation
|
||||
const stats = orders.reduce((acc, order) => {
|
||||
const product = products.find(p => p.id === order.product);
|
||||
acc.totalRevenue += order.quantity * product.price;
|
||||
acc.orderCount++;
|
||||
return acc;
|
||||
}, { totalRevenue: 0, orderCount: 0 });
|
||||
// Fetches all data, slow, memory-intensive
|
||||
```
|
||||
|
||||
**Correct (using view collection):**
|
||||
|
||||
```javascript
|
||||
// Create a view collection in PocketBase Admin UI or via API
|
||||
// View SQL:
|
||||
// SELECT
|
||||
// p.id,
|
||||
// p.name,
|
||||
// COUNT(o.id) as order_count,
|
||||
// SUM(o.quantity) as total_sold,
|
||||
// SUM(o.quantity * p.price) as revenue
|
||||
// FROM products p
|
||||
// LEFT JOIN orders o ON o.product = p.id
|
||||
// GROUP BY p.id
|
||||
|
||||
// Simple, efficient query
|
||||
const productStats = await pb.collection('product_stats').getList(1, 20, {
|
||||
sort: '-revenue'
|
||||
});
|
||||
|
||||
// Each record has computed fields
|
||||
productStats.items.forEach(stat => {
|
||||
console.log(`${stat.name}: ${stat.order_count} orders, $${stat.revenue}`);
|
||||
});
|
||||
```
|
||||
|
||||
**View collection use cases:**
|
||||
- Aggregations (COUNT, SUM, AVG)
|
||||
- Joining data from multiple collections
|
||||
- Computed/derived fields
|
||||
- Denormalized read models
|
||||
- Dashboard statistics
|
||||
|
||||
**Limitations:**
|
||||
- Read-only (no create/update/delete)
|
||||
- Must return `id` column
|
||||
- No realtime subscriptions
|
||||
- API rules still apply for access control

# File Handling
|
||||
|
||||
**Impact: MEDIUM**
|
||||
|
||||
File uploads, URL generation, thumbnail creation, and validation patterns.
|
||||
|
||||
---
|
||||
|
||||
## 1. Generate File URLs Correctly
|
||||
|
||||
**Impact: MEDIUM (Proper URLs with thumbnails and access control)**
|
||||
|
||||
Use the SDK's `getURL` method to generate proper file URLs with thumbnail support and access tokens for protected files.
|
||||
|
||||
**Incorrect (manually constructing URLs):**
|
||||
|
||||
```javascript
|
||||
// Hardcoded URL construction - brittle
|
||||
const imageUrl = `http://localhost:8090/api/files/${record.collectionId}/${record.id}/${record.image}`;
|
||||
|
||||
// Missing token for protected files
|
||||
const privateUrl = pb.files.getURL(record, record.document);
|
||||
// Returns URL but file access denied if protected!
|
||||
|
||||
// Wrong thumbnail syntax
|
||||
const thumb = `${imageUrl}?thumb=100x100`; // Wrong format
|
||||
```
|
||||
|
||||
**Correct (using SDK methods):**
|
||||
|
||||
```javascript
|
||||
// Basic file URL
|
||||
const imageUrl = pb.files.getURL(record, record.image);
|
||||
// Returns: http://host/api/files/COLLECTION/RECORD_ID/filename.jpg
|
||||
|
||||
// With thumbnail (for images only)
|
||||
const thumbUrl = pb.files.getURL(record, record.image, {
|
||||
thumb: '100x100' // Width x Height
|
||||
});
|
||||
|
||||
// Thumbnail options
|
||||
const thumbs = {
|
||||
square: pb.files.getURL(record, record.image, { thumb: '100x100' }),
|
||||
fit: pb.files.getURL(record, record.image, { thumb: '100x0' }), // Fit width
|
||||
fitHeight: pb.files.getURL(record, record.image, { thumb: '0x100' }), // Fit height
|
||||
crop: pb.files.getURL(record, record.image, { thumb: '100x100t' }), // Top crop
|
||||
cropBottom: pb.files.getURL(record, record.image, { thumb: '100x100b' }), // Bottom
|
||||
force: pb.files.getURL(record, record.image, { thumb: '100x100f' }), // Force exact
|
||||
};
|
||||
|
||||
// Protected files (require auth)
|
||||
async function getProtectedFileUrl(record, filename) {
|
||||
// Get file access token (valid for limited time)
|
||||
const token = await pb.files.getToken();
|
||||
|
||||
// Include token in URL
|
||||
return pb.files.getURL(record, filename, { token });
|
||||
}
|
||||
|
||||
// Example with protected document
|
||||
async function downloadDocument(record) {
|
||||
const token = await pb.files.getToken();
|
||||
const url = pb.files.getURL(record, record.document, { token });
|
||||
|
||||
// Token is appended: ...?token=xxx
|
||||
window.open(url, '_blank');
|
||||
}
|
||||
```
|
||||
|
||||
**React component example:**
|
||||
|
||||
```jsx
|
||||
function UserAvatar({ user, size = 50 }) {
|
||||
if (!user.avatar) {
|
||||
return <DefaultAvatar size={size} />;
|
||||
}
|
||||
|
||||
const avatarUrl = pb.files.getURL(user, user.avatar, {
|
||||
thumb: `${size}x${size}`
|
||||
});
|
||||
|
||||
return (
|
||||
<img
|
||||
src={avatarUrl}
|
||||
alt={user.name}
|
||||
width={size}
|
||||
height={size}
|
||||
loading="lazy"
|
||||
/>
|
||||
);
|
||||
}
|
||||
|
||||
function ImageGallery({ record }) {
|
||||
// Record has multiple images
|
||||
const images = record.images || [];
|
||||
|
||||
return (
|
||||
<div className="gallery">
|
||||
{images.map((filename, index) => (
|
||||
<img
|
||||
key={filename}
|
||||
src={pb.files.getURL(record, filename, { thumb: '200x200' })}
|
||||
onClick={() => openFullSize(record, filename)}
|
||||
loading="lazy"
|
||||
/>
|
||||
))}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
function openFullSize(record, filename) {
|
||||
const fullUrl = pb.files.getURL(record, filename);
|
||||
window.open(fullUrl, '_blank');
|
||||
}
|
||||
```
|
||||
|
||||
**Handling file URLs in lists:**
|
||||
|
||||
```javascript
|
||||
// Efficiently generate URLs for list of records
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
expand: 'author'
|
||||
});
|
||||
|
||||
const postsWithUrls = posts.items.map(post => ({
|
||||
...post,
|
||||
thumbnailUrl: post.image
|
||||
? pb.files.getURL(post, post.image, { thumb: '300x200' })
|
||||
: null,
|
||||
authorAvatarUrl: post.expand?.author?.avatar
|
||||
? pb.files.getURL(post.expand.author, post.expand.author.avatar, { thumb: '40x40' })
|
||||
: null
|
||||
}));
|
||||
```
|
||||
|
||||
**Thumbnail format reference:**
|
||||
|
||||
| Format | Description |
|
||||
|--------|-------------|
|
||||
| `WxH` | Fit within dimensions |
|
||||
| `Wx0` | Fit width, auto height |
|
||||
| `0xH` | Auto width, fit height |
|
||||
| `WxHt` | Crop from top |
|
||||
| `WxHb` | Crop from bottom |
|
||||
| `WxHf` | Force exact dimensions |
|
||||
|
||||
**Performance and caching:**
|
||||
|
||||
```javascript
|
||||
// File URLs are effectively immutable (randomized filenames on upload).
|
||||
// This makes them ideal for aggressive caching.
|
||||
|
||||
// Configure Cache-Control via reverse proxy (Nginx/Caddy):
|
||||
// location /api/files/ { add_header Cache-Control "public, immutable, max-age=86400"; }
|
||||
|
||||
// Thumbnails are generated on first request and cached by PocketBase.
|
||||
// Pre-generate expected thumb sizes after upload to avoid cold-start latency:
|
||||
async function uploadWithThumbs(record, file) {
|
||||
const updated = await pb.collection('posts').update(record.id, { image: file });
|
||||
|
||||
// Pre-warm thumbnail cache by requesting expected sizes
|
||||
const sizes = ['100x100', '300x200', '800x600'];
|
||||
await Promise.all(sizes.map(size =>
|
||||
fetch(pb.files.getURL(updated, updated.image, { thumb: size }))
|
||||
));
|
||||
|
||||
return updated;
|
||||
}
|
||||
```
|
||||
|
||||
**S3 file serving optimization:**
|
||||
|
||||
When using S3 storage, PocketBase proxies all file requests through the server. For better performance with public files, serve directly from your S3 CDN:
|
||||
|
||||
```javascript
|
||||
// Default: All file requests proxy through PocketBase
|
||||
const url = pb.files.getURL(record, record.image);
|
||||
// -> https://myapp.com/api/files/COLLECTION/ID/filename.jpg (proxied)
|
||||
|
||||
// For public files with S3 + CDN, construct CDN URL directly:
|
||||
const cdnBase = 'https://cdn.myapp.com'; // Your S3 CDN domain
|
||||
const cdnUrl = `${cdnBase}/${record.collectionId}/${record.id}/${record.image}`;
|
||||
// Bypasses PocketBase, served directly from CDN edge
|
||||
|
||||
// NOTE: This only works for public files (no access token needed).
|
||||
// Protected files must go through PocketBase for token validation.
|
||||
```
|
||||
|
||||
Reference: [PocketBase Files](https://pocketbase.io/docs/files-handling/)
|
||||
|
||||
> **Note (JS SDK v0.26.7):** `pb.files.getURL()` now serializes query parameters the same way as the fetch methods — passing `null` or `undefined` as a query param value is silently skipped from the generated URL, so you no longer need to guard optional params before passing them to `getURL()`.
|
||||
|
||||
## 2. Upload Files Correctly
|
||||
|
||||
**Impact: MEDIUM (Reliable uploads with progress tracking and validation)**
|
||||
|
||||
File uploads can use plain objects or FormData. Handle large files properly with progress tracking and appropriate error handling.
|
||||
|
||||
**Incorrect (naive file upload):**
|
||||
|
||||
```javascript
|
||||
// Missing error handling
|
||||
async function uploadFile(file) {
|
||||
await pb.collection('documents').create({
|
||||
title: file.name,
|
||||
file: file
|
||||
});
|
||||
// No error handling, no progress feedback
|
||||
}
|
||||
|
||||
// Uploading without validation
|
||||
async function uploadAvatar(file) {
|
||||
await pb.collection('users').update(userId, {
|
||||
avatar: file // No size/type check - might fail server-side
|
||||
});
|
||||
}
|
||||
|
||||
// Base64 upload (inefficient)
|
||||
async function uploadImage(base64) {
|
||||
await pb.collection('images').create({
|
||||
image: base64 // Wrong! PocketBase expects File/Blob
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (proper file uploads):**
|
||||
|
||||
```javascript
|
||||
// Basic upload with object (auto-converts to FormData)
|
||||
async function uploadDocument(file, metadata) {
|
||||
try {
|
||||
const record = await pb.collection('documents').create({
|
||||
title: metadata.title,
|
||||
description: metadata.description,
|
||||
file: file // File object from input
|
||||
});
|
||||
return record;
|
||||
} catch (error) {
|
||||
if (error.response?.data?.file) {
|
||||
throw new Error(`File error: ${error.response.data.file.message}`);
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Upload multiple files
|
||||
async function uploadGallery(files, albumId) {
|
||||
const record = await pb.collection('albums').update(albumId, {
|
||||
images: files // Array of File objects
|
||||
});
|
||||
return record;
|
||||
}
|
||||
|
||||
// FormData for more control
|
||||
async function uploadWithProgress(file, onProgress) {
|
||||
const formData = new FormData();
|
||||
formData.append('title', file.name);
|
||||
formData.append('file', file);
|
||||
|
||||
// Using fetch directly for progress (SDK doesn't expose progress)
|
||||
return new Promise((resolve, reject) => {
|
||||
const xhr = new XMLHttpRequest();
|
||||
|
||||
xhr.upload.addEventListener('progress', (e) => {
|
||||
if (e.lengthComputable) {
|
||||
onProgress(Math.round((e.loaded / e.total) * 100));
|
||||
}
|
||||
});
|
||||
|
||||
xhr.addEventListener('load', () => {
|
||||
if (xhr.status >= 200 && xhr.status < 300) {
|
||||
resolve(JSON.parse(xhr.responseText));
|
||||
} else {
|
||||
reject(new Error(`Upload failed: ${xhr.status}`));
|
||||
}
|
||||
});
|
||||
|
||||
xhr.addEventListener('error', () => reject(new Error('Upload failed')));
|
||||
|
||||
xhr.open('POST', `${pb.baseURL}/api/collections/documents/records`);
|
||||
xhr.setRequestHeader('Authorization', pb.authStore.token);
|
||||
xhr.send(formData);
|
||||
});
|
||||
}
|
||||
|
||||
// Client-side validation before upload
|
||||
function validateFile(file, options = {}) {
|
||||
const {
|
||||
maxSize = 10 * 1024 * 1024, // 10MB default
|
||||
allowedTypes = ['image/jpeg', 'image/png', 'image/gif', 'application/pdf'],
|
||||
maxNameLength = 100
|
||||
} = options;
|
||||
|
||||
const errors = [];
|
||||
|
||||

|
||||
## 3. Validate File Uploads
|
||||
|
||||
**Impact: MEDIUM (Prevents invalid uploads, improves security and UX)**
|
||||
|
||||
Validate files on both client and server side. Client validation improves UX; server validation (via collection settings) enforces security.
|
||||
|
||||
**Incorrect (no validation):**
|
||||
|
||||
```javascript
|
||||
// Accepting any file without checks
|
||||
async function uploadFile(file) {
|
||||
return pb.collection('uploads').create({ file });
|
||||
// Could upload 1GB executable!
|
||||
}
|
||||
|
||||
// Only checking extension (easily bypassed)
|
||||
function validateFile(file) {
|
||||
const ext = file.name.split('.').pop();
|
||||
return ['jpg', 'png'].includes(ext);
|
||||
// User can rename virus.exe to virus.jpg
|
||||
}
|
||||
|
||||
// Client-only validation (can be bypassed)
|
||||
async function uploadAvatar(file) {
|
||||
if (file.size > 1024 * 1024) {
|
||||
throw new Error('Too large');
|
||||
}
|
||||
// Attacker can bypass this with dev tools
|
||||
return pb.collection('users').update(userId, { avatar: file });
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (comprehensive validation):**
|
||||
|
||||
```javascript
|
||||
// 1. Configure server-side validation in collection settings
|
||||
// In Admin UI or via API:
|

# Production & Deployment
|
||||
|
||||
**Impact: LOW-MEDIUM**
|
||||
|
||||
Backup strategies, configuration management, reverse proxy setup, and SQLite optimization.
|
||||
|
||||
---
|
||||
|
||||
## 1. Implement Proper Backup Strategies
|
||||
|
||||
**Impact: LOW-MEDIUM (Prevents data loss, enables disaster recovery)**
|
||||
|
||||
Regular backups are essential for production deployments. PocketBase provides built-in backup functionality and supports external S3 storage.
|
||||
|
||||
**Incorrect (no backup strategy):**
|
||||
|
||||
```javascript
|
||||
// No backups at all - disaster waiting to happen
|
||||
// Just running: ./pocketbase serve
|
||||
|
||||
// Manual file copy while server running - can corrupt data
|
||||
// cp pb_data/data.db backup/
|
||||
|
||||
// Only backing up database, missing files
|
||||
// sqlite3 pb_data/data.db ".backup backup.db"
|
||||
```
|
||||
|
||||
**Correct (comprehensive backup strategy):**
|
||||
|
||||
```javascript
|
||||
// 1. Using PocketBase Admin API for backups
|
||||
const adminPb = new PocketBase('http://127.0.0.1:8090');
|
||||
await adminPb.collection('_superusers').authWithPassword(admin, password);
|
||||
|
||||
// Create backup (includes database and files)
|
||||
async function createBackup(name = '') {
|
||||
const backup = await adminPb.backups.create(name);
|
||||
console.log('Backup created:', backup.key);
|
||||
return backup;
|
||||
}
|
||||
|
||||
// List available backups
|
||||
async function listBackups() {
|
||||
const backups = await adminPb.backups.getFullList();
|
||||
backups.forEach(b => {
|
||||
console.log(`${b.key} - ${b.size} bytes - ${b.modified}`);
|
||||
});
|
||||
return backups;
|
||||
}
|
||||
|
||||
// Download backup
|
||||
async function downloadBackup(key) {
|
||||
const token = await adminPb.files.getToken();
|
||||
const url = adminPb.backups.getDownloadURL(token, key);
|
||||
// url can be used to download the backup file
|
||||
return url;
|
||||
}
|
||||
|
||||
// Restore from backup (CAUTION: overwrites current data!)
|
||||
async function restoreBackup(key) {
|
||||
await adminPb.backups.restore(key);
|
||||
console.log('Restore initiated - server will restart');
|
||||
}
|
||||
|
||||
// Delete old backups
|
||||
async function cleanupOldBackups(keepCount = 7) {
|
||||
const backups = await adminPb.backups.getFullList();
|
||||
|
||||
// Sort by date, keep newest
|
||||
const sorted = backups.sort((a, b) =>
|
||||
new Date(b.modified) - new Date(a.modified)
|
||||
);
|
||||
|
||||
const toDelete = sorted.slice(keepCount);
|
||||
for (const backup of toDelete) {
|
||||
await adminPb.backups.delete(backup.key);
|
||||
console.log('Deleted old backup:', backup.key);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Automated backup script (cron job):**
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# backup.sh - Run daily via cron
|
||||
|
||||
POCKETBASE_URL="http://127.0.0.1:8090"
|
||||
ADMIN_EMAIL="admin@example.com"
|
||||
ADMIN_PASSWORD="your-secure-password"
|
||||
BACKUP_DIR="/path/to/backups"
|
||||
KEEP_DAYS=7
|
||||
|
||||
# Create timestamp
|
||||
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
|
||||
|
||||
# Create backup via API
|
||||
curl -X POST "${POCKETBASE_URL}/api/backups" \
|
||||
-H "Authorization: $(curl -s -X POST "${POCKETBASE_URL}/api/collections/_superusers/auth-with-password" \
|
||||
-d "identity=${ADMIN_EMAIL}&password=${ADMIN_PASSWORD}" | jq -r '.token')" \
|
||||
-d "name=backup_${TIMESTAMP}"
|
||||
|
||||
# Clean old local backups
|
||||
find "${BACKUP_DIR}" -name "*.zip" -mtime +${KEEP_DAYS} -delete
|
||||
|
||||
echo "Backup completed: backup_${TIMESTAMP}"
|
||||
```
|
||||
|
||||
**Configure S3 for backup storage:**
|
||||
|
||||
```javascript
|
||||
// In Admin UI: Settings > Backups > S3
|
||||
// Or via API:
|
||||
await adminPb.settings.update({
|
||||
backups: {
|
||||
s3: {
|
||||
enabled: true,
|
||||
bucket: 'my-pocketbase-backups',
|
||||
region: 'us-east-1',
|
||||
endpoint: 's3.amazonaws.com',
|
||||
accessKey: process.env.AWS_ACCESS_KEY,
|
||||
secret: process.env.AWS_SECRET_KEY
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**Backup best practices:**
|
||||
|
||||
| Aspect | Recommendation |
|
||||
|--------|---------------|
|
||||
| Frequency | Daily minimum, hourly for critical apps |
|
||||
| Retention | 7-30 days of daily backups |
|
||||
| Storage | Off-site (S3, separate server) |
|
||||
| Testing | Monthly restore tests |
|
||||
| Monitoring | Alert on backup failures |
|
||||
|
||||
**Pre-backup checklist:**
|
||||
- [ ] S3 or external storage configured
|
||||
- [ ] Automated schedule set up
|
||||
- [ ] Retention policy defined
|
||||
- [ ] Restore procedure documented
|
||||
- [ ] Restore tested successfully
|
||||

|
||||
|
||||
## 2. Configure Production Settings Properly
|
||||
|
||||
**Impact: LOW-MEDIUM (Secure and optimized production environment)**
|
||||
|
||||
Production deployments require proper configuration of URLs, secrets, SMTP, and security settings.
|
||||
|
||||
**Incorrect (development defaults in production):**
|
||||
|
||||
```bash
|
||||
# Running with defaults - insecure!
|
||||
./pocketbase serve
|
||||
|
||||
# Hardcoded secrets
|
||||
./pocketbase serve --encryptionEnv="mySecretKey123"
|
||||
|
||||
# Wrong origin for CORS
|
||||
# Leaving http://localhost:8090 as allowed origin
|
||||
```
|
||||
|
||||
**Correct (production configuration):**
|
||||
|
||||
```bash
|
||||
# Production startup with essential flags
|
||||
./pocketbase serve \
|
||||
--http="0.0.0.0:8090" \
|
||||
--origins="https://myapp.com,https://www.myapp.com" \
|
||||
--encryptionEnv="PB_ENCRYPTION_KEY"
|
||||
|
||||
# Using environment variables
|
||||
export PB_ENCRYPTION_KEY="your-32-char-encryption-key-here"
|
||||
export SMTP_HOST="smtp.sendgrid.net"
|
||||
export SMTP_PORT="587"
|
||||
export SMTP_USER="apikey"
|
||||
export SMTP_PASS="your-sendgrid-api-key"
|
||||
|
||||
./pocketbase serve --http="0.0.0.0:8090"
|
||||
```
|
||||
|
||||
**Configure SMTP for emails:**
|
||||
|
||||
```javascript
|
||||
// Via Admin UI or API
|
||||
await adminPb.settings.update({
|
||||
smtp: {
|
||||
enabled: true,
|
||||
host: process.env.SMTP_HOST,
|
||||
port: parseInt(process.env.SMTP_PORT),
|
||||
username: process.env.SMTP_USER,
|
||||
password: process.env.SMTP_PASS,
|
||||
tls: true
|
||||
},
|
||||
meta: {
|
||||
appName: 'My App',
|
||||
appURL: 'https://myapp.com',
|
||||
senderName: 'My App',
|
||||
senderAddress: 'noreply@myapp.com'
|
||||
}
|
||||
});
|
||||
|
||||
// Test email configuration
|
||||
await adminPb.settings.testEmail('users', 'test@example.com', 'verification');
|
||||
```
|
||||
|
||||
**Configure S3 for file storage:**
|
||||
|
||||
```javascript
|
||||
// Move file storage to S3 for scalability
|
||||
await adminPb.settings.update({
|
||||
s3: {
|
||||
enabled: true,
|
||||
bucket: 'my-app-files',
|
||||
region: 'us-east-1',
|
||||
endpoint: 's3.amazonaws.com',
|
||||
accessKey: process.env.AWS_ACCESS_KEY,
|
||||
secret: process.env.AWS_SECRET_KEY,
|
||||
forcePathStyle: false
|
||||
}
|
||||
});
|
||||
|
||||
// Test S3 connection
|
||||
await adminPb.settings.testS3('storage');
|
||||
```
|
||||
|
||||

```
|
||||
|

**Production checklist:**
|
||||
|
||||
- [ ] HTTPS enabled (via reverse proxy)
|
||||
- [ ] Strong encryption key set

## 3. Enable Rate Limiting for API Protection
|
||||
|
||||
**Impact: MEDIUM (Prevents abuse, brute-force attacks, and DoS)**
|
||||
|
||||
PocketBase v0.23+ includes built-in rate limiting. Enable it to protect against brute-force attacks, API abuse, and excessive resource consumption.
|
||||
|
||||
> **v0.36.7 behavioral change:** the built-in limiter switched from a sliding-window to a **fixed-window** strategy. This is cheaper and more predictable, but it means a client can send `2 * maxRequests` in quick succession if they straddle the window boundary. Size your limits with that worst case in mind, and put Nginx/Caddy rate limiting in front of PocketBase for defense in depth (see examples below).
|
||||
|
||||
**Incorrect (no rate limiting):**
|
||||
|
||||
```bash
|
||||
# Running without rate limiting
|
||||
./pocketbase serve
|
||||
|
||||
# Vulnerable to:
|
||||
# - Brute-force password attacks
|
||||
# - API abuse and scraping
|
||||
# - DoS from excessive requests
|
||||
# - Account enumeration attempts
|
||||
```
|
||||
|
||||
**Correct (enable rate limiting):**
|
||||
|
||||
```bash
|
||||
# Enable via command line flag
|
||||
./pocketbase serve --rateLimiter=true
|
||||
|
||||
# Or configure specific limits (requests per second per IP)
|
||||
./pocketbase serve --rateLimiter=true --rateLimiterRPS=10
|
||||
```
|
||||
|
||||
**Configure via Admin Dashboard:**
|
||||
|
||||
Navigate to Settings > Rate Limiter:
|
||||
- **Enable rate limiter**: Toggle on
|
||||
- **Max requests/second**: Default 10, adjust based on needs
|
||||
- **Exempt endpoints**: Optionally whitelist certain paths
|
||||
|
||||
**Configure programmatically (Go/JS hooks):**
|
||||
|
||||
```javascript
|
||||
// In pb_hooks/rate_limit.pb.js
|
||||
routerAdd("GET", "/api/public/*", (e) => {
|
||||
// Custom rate limit for specific endpoints
|
||||
}, $apis.rateLimit(100, "10s")); // 100 requests per 10 seconds
|
||||
|
||||
// Stricter limit for auth endpoints
|
||||
routerAdd("POST", "/api/collections/users/auth-*", (e) => {
|
||||
// Auth endpoints need stricter limits
|
||||
}, $apis.rateLimit(5, "1m")); // 5 attempts per minute
|
||||
```
|
||||
|
||||
**Rate limiting with reverse proxy (additional layer):**
|
||||
|
||||
```nginx
|
||||
# Nginx rate limiting (defense in depth)
|
||||
http {
|
||||
# Define rate limit zones
|
||||
limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;
|
||||
limit_req_zone $binary_remote_addr zone=auth:10m rate=1r/s;
|
||||
|
||||
server {
|
||||
# General API rate limit
|
||||
location /api/ {
|
||||
limit_req zone=api burst=20 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
|
||||
# Strict limit for auth endpoints
|
||||
location /api/collections/users/auth {
|
||||
limit_req zone=auth burst=5 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
|
||||
# Stricter limit for superuser auth
|
||||
location /api/collections/_superusers/auth {
|
||||
limit_req zone=auth burst=3 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```caddyfile
|
||||
# Caddy with rate limiting plugin
|
||||
myapp.com {
|
||||
rate_limit {
|
||||
zone api {
|
||||
key {remote_host}
|
||||
events 100
|
||||
window 10s
|
||||
}
|
||||
zone auth {
|
||||
key {remote_host}
|
||||
events 5
|
||||
window 1m
|
||||
}
|
||||
}
|
||||
|
||||
@auth path /api/collections/*/auth*
|
||||
handle @auth {
|
||||
rate_limit { zone auth }
|
||||
reverse_proxy 127.0.0.1:8090
|
||||
}
|
||||
|
||||
handle {
|
||||
rate_limit { zone api }
|
||||
reverse_proxy 127.0.0.1:8090
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Handle rate limit errors in client:**
|
||||
|
||||
```javascript
|
||||
async function makeRequest(fn, retries = 0, maxRetries = 3) {
|
||||
try {
|
||||
return await fn();
|
||||
} catch (error) {
|
||||
if (error.status === 429 && retries < maxRetries) {
|
||||
// Rate limited - wait and retry with limit
|
||||
const retryAfter = error.response?.retryAfter || 60;
|
||||
console.log(`Rate limited. Retry ${retries + 1}/${maxRetries} after ${retryAfter}s`);
|
||||
|
||||
// Show user-friendly message
|
||||
showMessage('Too many requests. Please wait a moment.');
|
||||
|
||||
await sleep(retryAfter * 1000);
|
||||
return makeRequest(fn, retries + 1, maxRetries);
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
const result = await makeRequest(() =>
|
||||
pb.collection('posts').getList(1, 20)
|
||||
);
|
||||
```
|
||||
|
||||
**Recommended limits by endpoint type:**
|
||||
|
||||
| Endpoint Type | Suggested Limit | Reason |
|
||||
|--------------|-----------------|--------|
|
||||
| Auth endpoints | 5-10/min | Prevent brute-force |
|
||||
| Password reset | 3/hour | Prevent enumeration |
|
||||
| Record creation | 30/min | Prevent spam |
|
||||
| General API | 60-100/min | Normal usage |
|
||||
| Public read | 100-200/min | Higher for reads |
|
||||
| File uploads | 10/min | Resource-intensive |
|
||||
|
||||
**Monitoring rate limit hits:**
|
||||
|
||||
```javascript
|
||||
// Check PocketBase logs for rate limit events
|
||||
// Or set up alerting in your monitoring system
|
||||
|
||||
// Client-side tracking
|
||||
pb.afterSend = function(response, data) {
|
||||
if (response.status === 429) {
|
||||
trackEvent('rate_limit_hit', {
|
||||
endpoint: response.url,
|
||||
timestamp: new Date()
|
||||
});
|
||||
}
|
||||
return data;
|
||||
};
|
||||
```

|
||||
|
||||
## 4. Configure Reverse Proxy Correctly
|
||||
|
||||
**Impact: LOW-MEDIUM (HTTPS, caching, rate limiting, and security headers)**
|
||||
|
||||
Use a reverse proxy (Nginx, Caddy) for HTTPS termination, caching, rate limiting, and security headers.
|
||||
|
||||
**Incorrect (exposing PocketBase directly):**
|
||||
|
||||
```bash
|
||||
# Direct exposure - no HTTPS, no rate limiting
|
||||
./pocketbase serve --http="0.0.0.0:8090"
|
||||
|
||||
# Port forwarding without proxy
|
||||
iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8090
|
||||
# Still no HTTPS!
|
||||
```
|
||||
|
||||
**Correct (Caddy - simplest option):**
|
||||
|
||||
```caddyfile
|
||||
# /etc/caddy/Caddyfile
|
||||
myapp.com {
|
||||
# Automatic HTTPS via Let's Encrypt
|
||||
reverse_proxy 127.0.0.1:8090 {
|
||||
# Required for SSE/Realtime
|
||||
flush_interval -1
|
||||
}
|
||||
|
||||
# Security headers
|
||||
header {
|
||||
X-Content-Type-Options "nosniff"
|
||||
X-Frame-Options "DENY"
|
||||
Strict-Transport-Security "max-age=63072000; includeSubDomains; preload"
|
||||
Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'"
|
||||
Referrer-Policy "strict-origin-when-cross-origin"
|
||||
-Server
|
||||
}
|
||||
|
||||
# Restrict admin UI to internal/VPN networks
|
||||
# @admin path /_/*
|
||||
# handle @admin {
|
||||
# @blocked not remote_ip 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16
|
||||
# respond @blocked 403
|
||||
# reverse_proxy 127.0.0.1:8090
|
||||
# }
|
||||
|
||||
# Rate limiting (requires caddy-ratelimit plugin)
|
||||
# Install: xcaddy build --with github.com/mholt/caddy-ratelimit
|
||||
# Without this plugin, use PocketBase's built-in rate limiter (--rateLimiter=true)
|
||||
# rate_limit {
|
||||
# zone api {
|
||||
# key {remote_host}
|
||||
# events 100
|
||||
# window 1m
|
||||
# }
|
||||
# }
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (Nginx configuration):**
|
||||
|
||||
```nginx
|
||||
# /etc/nginx/sites-available/pocketbase
|
||||
|
||||
# Rate limit zones must be defined in http context (e.g., /etc/nginx/nginx.conf)
|
||||
# limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;

## 5. Tune OS and Runtime for PocketBase Scale
|
||||
|
||||
**Impact: MEDIUM (Prevents file descriptor exhaustion, OOM kills, and exposes secure config for production deployments)**
|
||||
|
||||
Three low-effort OS/runtime knobs have outsized impact on production stability: open-file limits for realtime connections, Go memory limits for constrained hosts, and settings encryption for shared or externally-backed infrastructure. None of these are set automatically.
|
||||
|
||||
**Incorrect (default OS limits, no memory governor, plain-text settings):**
|
||||
|
||||
```bash
|
||||
# Start without raising the file descriptor limit
|
||||
/root/pb/pocketbase serve yourdomain.com
|
||||
# → "Too many open files" once concurrent realtime connections exceed ~1024
|
||||
|
||||
# Start in a container that has a 512 MB RAM cap without GOMEMLIMIT
|
||||
docker run -m 512m pocketbase serve ...
|
||||
# → OOM kill during large file upload because Go GC doesn't respect cgroup limits
|
||||
|
||||
# Store SMTP password and S3 secret as plain JSON in pb_data/data.db
|
||||
pocketbase serve # no --encryptionEnv
|
||||
# → Anyone who obtains the database backup can read all credentials
|
||||
```
|
||||
|
||||
**Correct:**
|
||||
|
||||
```bash
|
||||
# 1. Raise the open-file limit before starting (Linux/macOS)
|
||||
# Check current limit first:
|
||||
ulimit -a | grep "open files"
|
||||
# Temporarily raise to 4096 for the current session:
|
||||
ulimit -n 4096
|
||||
/root/pb/pocketbase serve yourdomain.com
|
||||
|
||||
# Or persist it via systemd (recommended for production):
|
||||
# /lib/systemd/system/pocketbase.service
|
||||
# [Service]
|
||||
# LimitNOFILE = 4096
|
||||
# ...
|
||||
|
||||
# 2. Cap Go's soft memory target on memory-constrained hosts
|
||||
# (instructs the GC to be more aggressive before the kernel OOM-kills the process)
|
||||
GOMEMLIMIT=512MiB /root/pb/pocketbase serve yourdomain.com
|
||||
|
||||
# 3. Encrypt application settings at rest
|
||||
# Generate a random 32-character key once:
|
||||
export PB_ENCRYPTION_KEY="z76NX9WWiB05UmQGxw367B6zM39T11fF"
|
||||
# Start with the env-var name (not the value) as the flag argument:
|
||||
pocketbase serve --encryptionEnv=PB_ENCRYPTION_KEY
|
||||
```
|
||||
|
||||
**Docker deployment pattern (v0.36.8):**
|
||||
|
||||
```dockerfile
|
||||
FROM alpine:latest
|
||||
ARG PB_VERSION=0.36.8
|
||||
|
||||
RUN apk add --no-cache unzip ca-certificates
|
||||
|
||||
ADD https://github.com/pocketbase/pocketbase/releases/download/v${PB_VERSION}/pocketbase_${PB_VERSION}_linux_amd64.zip /tmp/pb.zip
|
||||
RUN unzip /tmp/pb.zip -d /pb/
|
||||
|
||||
# Uncomment to bundle pre-written migrations or hooks:
|
||||
# COPY ./pb_migrations /pb/pb_migrations
|
||||
# COPY ./pb_hooks /pb/pb_hooks
|
||||
|
||||
EXPOSE 8080
|
||||
|
||||
# Mount a volume at /pb/pb_data to persist data across container restarts
|
||||
CMD ["/pb/pocketbase", "serve", "--http=0.0.0.0:8080"]
|
||||
```
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
services:
|
||||
pocketbase:
|
||||
build: .
|
||||
ports:
|
||||
- "8080:8080"
|
||||
volumes:
|
||||
- pb_data:/pb/pb_data
|
||||
environment:
|
||||
GOMEMLIMIT: "512MiB"
|
||||
PB_ENCRYPTION_KEY: "${PB_ENCRYPTION_KEY}"
|
||||

|
||||
volumes:
|
||||
pb_data:
|
||||
```
|
||||
|
||||
**Quick-reference checklist:**
|
||||
|
||||
| Concern | Fix |
|
||||
|---------|-----|
|
||||
| `Too many open files` errors | `ulimit -n 4096` (or `LimitNOFILE=4096` in systemd) |
|
||||
| OOM kill on constrained host | `GOMEMLIMIT=512MiB` env var |
|
||||
| Credentials visible in DB backup | `--encryptionEnv=YOUR_VAR` with a 32-char random key |
|
||||
| Persistent data in Docker | Mount volume at `/pb/pb_data` |

## 6. Optimize SQLite for Production
|
||||
|
||||
**Impact: LOW-MEDIUM (Better performance and reliability for SQLite database)**
|
||||
|
||||
PocketBase uses SQLite with optimized defaults. Understanding its characteristics helps optimize performance and avoid common pitfalls. PocketBase uses two separate databases: `data.db` (application data) and `auxiliary.db` (logs and ephemeral data), which reduces write contention.
|
||||
|
||||
**Incorrect (ignoring SQLite characteristics):**
|
||||
|
||||
```javascript
|
||||
// Heavy concurrent writes - SQLite bottleneck
|
||||
async function bulkInsert(items) {
|
||||
// Parallel writes cause lock contention
|
||||
await Promise.all(items.map(item =>
|
||||
pb.collection('items').create(item)
|
||||
));
|
||||
}
|
||||
|
||||
// Not using transactions for batch operations
|
||||
async function updateMany(items) {
|
||||
for (const item of items) {
|
||||
await pb.collection('items').update(item.id, item);
|
||||
}
|
||||
// Each write is a separate transaction - slow!
|
||||
}
|
||||
|
||||
// Large text fields without consideration
|
||||
const schema = [{
|
||||
name: 'content',
|
||||
type: 'text' // Could be megabytes - affects all queries
|
||||
}];
|
||||
```
|
||||
|
||||
**Correct (SQLite-optimized patterns):**
|
||||
|
||||
```javascript
|
||||
// Use batch operations for multiple writes
|
||||
async function bulkInsert(items) {
|
||||
const batch = pb.createBatch();
|
||||
items.forEach(item => {
|
||||
batch.collection('items').create(item);
|
||||
});
|
||||
await batch.send(); // Single transaction, much faster
|
||||
}
|
||||
|
||||
// Batch updates
|
||||
async function updateMany(items) {
|
||||
const batch = pb.createBatch();
|
||||
items.forEach(item => {
|
||||
batch.collection('items').update(item.id, item);
|
||||
});
|
||||
await batch.send();
|
||||
}
|
||||
|
||||
// For very large batches, chunk them
|
||||
async function bulkInsertLarge(items, chunkSize = 100) {
|
||||
for (let i = 0; i < items.length; i += chunkSize) {
|
||||
const chunk = items.slice(i, i + chunkSize);
|
||||
const batch = pb.createBatch();
|
||||
chunk.forEach(item => batch.collection('items').create(item));
|
||||
await batch.send();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Schema considerations:**
|
||||
|
||||
```javascript
|
||||
// Separate large content into dedicated collection
|
||||
const postsSchema = [
|
||||
{ name: 'title', type: 'text' },
|
||||
{ name: 'summary', type: 'text', options: { maxLength: 500 } },
|
||||
{ name: 'author', type: 'relation' }
|
||||
// Content in separate collection
|
||||
];
|
||||
|
||||
const postContentsSchema = [
|
||||
{ name: 'post', type: 'relation', required: true },
|
||||
{ name: 'content', type: 'editor' } // Large HTML content
|
||||
];
|
||||
|
||||
// Fetch content only when needed
|
||||
async function getPostList() {
|
||||
return pb.collection('posts').getList(1, 20); // Fast, no content
|
||||
}
|
||||
|
||||
async function getPostWithContent(id) {
|
||||
const post = await pb.collection('posts').getOne(id);
|
||||
const content = await pb.collection('post_contents').getFirstListItem(
|
||||
pb.filter('post = {:id}', { id })
|
||||
);
|
||||
return { ...post, content: content.content };
|
||||
}
|
||||
```
|
||||
|
||||
**PocketBase default PRAGMA settings:**
|
||||
|
||||
PocketBase already configures optimal SQLite settings. You do not need to set these manually unless using a custom SQLite driver:
|
||||
|
||||
```sql
|
||||
PRAGMA busy_timeout = 10000; -- Wait 10s for locks instead of failing immediately
|
||||
PRAGMA journal_mode = WAL; -- Write-Ahead Logging: concurrent reads during writes
|
||||
PRAGMA journal_size_limit = 200000000; -- Limit WAL file to ~200MB
|
||||
PRAGMA synchronous = NORMAL; -- Balanced durability/performance (safe with WAL)
|
||||
PRAGMA foreign_keys = ON; -- Enforce relation integrity
|
||||
PRAGMA temp_store = MEMORY; -- Temp tables in memory (faster sorts/joins)
|
||||
PRAGMA cache_size = -32000; -- 32MB page cache
|
||||
```
|
||||
|
||||
WAL mode is the most impactful setting -- it allows multiple concurrent readers while a single writer is active, which is critical for PocketBase's concurrent API request handling.
|
||||
|
||||
**Index optimization:**
|
||||
|
||||
```sql
|
||||
-- Create indexes for commonly filtered/sorted fields
|
||||
CREATE INDEX idx_posts_author ON posts(author);
|
||||
CREATE INDEX idx_posts_created ON posts(created DESC);
|
||||
CREATE INDEX idx_posts_status_created ON posts(status, created DESC);
|
||||
|
||||
-- Verify indexes are being used
|
||||
EXPLAIN QUERY PLAN
|
||||
SELECT * FROM posts WHERE author = 'xxx' ORDER BY created DESC;
|
||||
-- Should show: "USING INDEX idx_posts_author"
|
||||
```
|
||||
|
||||
**SQLite limitations and workarounds:**
|
||||
|
||||
| Limitation | Workaround |
|
||||
|------------|------------|
|
||||
| Single writer | Use batch operations, queue writes |
|
||||
| No full-text by default | Use view collections with FTS5 |
|
||||
| File-based | SSD storage, avoid network mounts |
|
||||
| Memory for large queries | Pagination, limit result sizes |
|
||||
|
||||
**Performance monitoring:**
|
||||
|
||||
```javascript
|
||||
// Monitor slow queries via hooks (requires custom PocketBase build)
|
||||
// Or use SQLite's built-in profiling
|
||||
|
||||
// From sqlite3 CLI:
|
||||
// .timer on
|
||||
// SELECT * FROM posts WHERE author = 'xxx';
|
||||
// Run Time: real 0.003 user 0.002 sys 0.001
|
||||
|
||||
// Check database size
|
||||
// ls -lh pb_data/data.db
|
||||
|
||||
// Vacuum to reclaim space after deletes
|
||||
// sqlite3 pb_data/data.db "VACUUM;"
|
||||
```
|
||||
|
||||
**When to consider alternatives:**
|
||||
|
||||
Consider migrating from single PocketBase if:
|
||||
- Write throughput consistently > 1000/sec needed
|
||||
- Database size > 100GB
|
||||
- Complex transactions across tables
|
||||
- Multi-region deployment required
|
||||
|
||||
**Custom SQLite driver (advanced):**
|
||||
|
||||
PocketBase supports custom SQLite drivers via `DBConnect`. The CGO driver (`mattn/go-sqlite3`) can offer better performance for some workloads and enables extensions like ICU and FTS5. This requires a custom PocketBase build:
|
||||
|
||||
```go
|
||||
// main.go (custom PocketBase build with CGO driver)
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/pocketbase/dbx"
|
||||
"github.com/pocketbase/pocketbase"
|
||||
_ "github.com/mattn/go-sqlite3" // CGO SQLite driver
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := pocketbase.NewWithConfig(pocketbase.Config{
|
||||
// Called twice: once for data.db, once for auxiliary.db
|
||||
DBConnect: func(dbPath string) (*dbx.DB, error) {
|
||||
return dbx.Open("sqlite3", dbPath)
|
||||
},
|
||||
})
|
||||
|
||||
if err := app.Start(); err != nil {
|
||||
panic(err)
|
||||
}
|
||||
}
|
||||
// Build with: CGO_ENABLED=1 go build
|
||||
```
|
||||
|
||||
Note: CGO requires C compiler toolchain and cannot be cross-compiled as easily as pure Go.
|
||||
|
||||
**Scaling options:**
|
||||
1. **Read replicas**: Litestream for SQLite replication
|
||||
2. **Sharding**: Multiple PocketBase instances by tenant/feature
|
||||
3. **Caching**: Redis/Memcached for read-heavy loads
|
||||
4. **Alternative backend**: If requirements exceed SQLite, evaluate PostgreSQL-based frameworks

# Query Performance
|
||||
|
||||
**Impact: HIGH**
|
||||
|
||||
Pagination strategies, relation expansion, field selection, batch operations, and N+1 query prevention.
|
||||
|
||||
---
|
||||
|
||||
## 1. Use Back-Relations for Inverse Lookups
|
||||
|
||||
**Impact: HIGH (Fetch related records without separate queries)**
|
||||
|
||||
Back-relations allow you to expand records that reference the current record, enabling inverse lookups in a single request. Use the `collectionName_via_fieldName` syntax.
|
||||
|
||||
**Incorrect (manual inverse lookup):**
|
||||
|
||||
```javascript
|
||||
// Fetching a user, then their posts separately
|
||||
async function getUserWithPosts(userId) {
|
||||
const user = await pb.collection('users').getOne(userId);
|
||||
|
||||
// Extra request for posts
|
||||
const posts = await pb.collection('posts').getList(1, 100, {
|
||||
filter: pb.filter('author = {:userId}', { userId })
|
||||
});
|
||||
|
||||
return { ...user, posts: posts.items };
|
||||
}
|
||||
// 2 API calls
|
||||
|
||||
// Fetching a post, then its comments
|
||||
async function getPostWithComments(postId) {
|
||||
const post = await pb.collection('posts').getOne(postId);
|
||||
const comments = await pb.collection('comments').getFullList({
|
||||
filter: pb.filter('post = {:postId}', { postId }),
|
||||
expand: 'author'
|
||||
});
|
||||
|
||||
return { ...post, comments };
|
||||
}
|
||||
// 2 API calls
|
||||
```
|
||||
|
||||
**Correct (using back-relation expand):**
|
||||
|
||||
```javascript
|
||||
// Expand posts that reference this user
|
||||
// posts collection has: author (relation to users)
|
||||
async function getUserWithPosts(userId) {
|
||||
const user = await pb.collection('users').getOne(userId, {
|
||||
expand: 'posts_via_author' // collectionName_via_fieldName
|
||||
});
|
||||
|
||||
console.log('User:', user.name);
|
||||
console.log('Posts:', user.expand?.posts_via_author);
|
||||
return user;
|
||||
}
|
||||
// 1 API call!
|
||||
|
||||
// Expand comments that reference this post
|
||||
// comments collection has: post (relation to posts)
|
||||
async function getPostWithComments(postId) {
|
||||
const post = await pb.collection('posts').getOne(postId, {
|
||||
expand: 'comments_via_post,comments_via_post.author'
|
||||
});
|
||||
|
||||
const comments = post.expand?.comments_via_post || [];
|
||||
comments.forEach(comment => {
|
||||
console.log(`${comment.expand?.author?.name}: ${comment.content}`);
|
||||
});
|
||||
|
||||
return post;
|
||||
}
|
||||
// 1 API call with nested expansion!
|
||||
|
||||
// Multiple back-relations
|
||||
async function getUserWithAllContent(userId) {
|
||||
const user = await pb.collection('users').getOne(userId, {
|
||||
expand: 'posts_via_author,comments_via_author,likes_via_user'
|
||||
});
|
||||
|
||||
return {
|
||||
user,
|
||||
posts: user.expand?.posts_via_author || [],
|
||||
comments: user.expand?.comments_via_author || [],
|
||||
likes: user.expand?.likes_via_user || []
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
**Back-relation syntax:**
|
||||
|
||||
```
|
||||
{referencing_collection}_via_{relation_field}
|
||||
|
||||
Examples:
|
||||
- posts_via_author -> posts where author = current record
|
||||
- comments_via_post -> comments where post = current record
|
||||
- order_items_via_order -> order_items where order = current record
|
||||
- team_members_via_team -> team_members where team = current record
|
||||
```
|
||||
|
||||
**Nested back-relations:**
|
||||
|
||||
```javascript
|
||||
// Get user with posts and each post's comments
|
||||
const user = await pb.collection('users').getOne(userId, {
|
||||
expand: 'posts_via_author.comments_via_post'
|
||||
});
|
||||
|
||||
// Access nested data
|
||||
const posts = user.expand?.posts_via_author || [];
|
||||
posts.forEach(post => {
|
||||
console.log('Post:', post.title);
|
||||
const comments = post.expand?.comments_via_post || [];
|
||||
comments.forEach(c => console.log(' Comment:', c.content));
|
||||
});
|
||||
```
|
||||
|
||||
**Important considerations:**
|
||||
|
||||
```javascript
|
||||
// Back-relations always return arrays, even if the relation field
|
||||
// is marked as single (maxSelect: 1)
|
||||
|
||||
// Limited to 1000 records per back-relation
|
||||
// For more, use separate paginated query
|
||||
const user = await pb.collection('users').getOne(userId, {
|
||||
expand: 'posts_via_author'
|
||||
});
|
||||
// If user has 1500 posts, only first 1000 are included
|
||||
|
||||
// For large datasets, use paginated approach
|
||||
async function getUserPostsPaginated(userId, page = 1) {
|
||||
return pb.collection('posts').getList(page, 50, {
|
||||
filter: pb.filter('author = {:userId}', { userId }),
|
||||
sort: '-created'
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Use in list queries:**
|
||||
|
||||
```javascript
|
||||
// Get all users with their post counts
|
||||
// (Use view collection for actual counts)
|
||||
const users = await pb.collection('users').getList(1, 20, {
|
||||
expand: 'posts_via_author'
|
||||
});
|
||||
|
||||
users.items.forEach(user => {
|
||||
const postCount = user.expand?.posts_via_author?.length || 0;
|
||||
console.log(`${user.name}: ${postCount} posts`);
|
||||
});
|
||||
```
|
||||
|
||||
**When to use back-relations vs separate queries:**
|
||||
|
||||
| Scenario | Approach |
|
||||
|----------|----------|
|
||||
| < 1000 related records | Back-relation expand |
|
||||
| Need pagination | Separate query with filter |
|
||||
| Need sorting/filtering | Separate query |
|
||||
| Just need count | View collection |
|
||||
| Display in list | Back-relation (if small) |
|
||||
|
||||
Reference: [PocketBase Back-Relations](https://pocketbase.io/docs/working-with-relations/#back-relation-expand)
|
||||
|
||||
## 2. Use Batch Operations for Multiple Writes
|
||||
|
||||
**Impact: HIGH (Atomic transactions, 10x fewer API calls, consistent state)**
|
||||
|
||||
Batch operations combine multiple create/update/delete operations into a single atomic transaction. This ensures consistency and dramatically reduces API calls.
|
||||
|
||||
**Incorrect (individual requests):**
|
||||
|
||||
```javascript
|
||||
// Creating multiple records individually
|
||||
async function createOrderWithItems(order, items) {
|
||||
// If any fails, partial data remains!
|
||||
const createdOrder = await pb.collection('orders').create(order);
|
||||
|
||||
for (const item of items) {
|
||||
await pb.collection('order_items').create({
|
||||
...item,
|
||||
order: createdOrder.id
|
||||
});
|
||||
}
|
||||
// 1 + N API calls, not atomic
|
||||
}
|
||||
|
||||
// Updating multiple records
|
||||
async function updatePrices(products) {
|
||||
for (const product of products) {
|
||||
await pb.collection('products').update(product.id, {
|
||||
price: product.newPrice
|
||||
});
|
||||
}
|
||||
// N API calls, some might fail leaving inconsistent state
|
||||
}
|
||||
|
||||
// Mixed operations
|
||||
async function transferFunds(fromId, toId, amount) {
|
||||
// NOT ATOMIC - can leave invalid state!
|
||||
await pb.collection('accounts').update(fromId, { 'balance-': amount });
|
||||
// If this fails, money disappears!
|
||||
await pb.collection('accounts').update(toId, { 'balance+': amount });
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using batch operations):**
|
||||
|
||||
```javascript
|
||||
// Atomic batch create
|
||||
async function createOrderWithItems(order, items) {
|
||||
const batch = pb.createBatch();
|
||||
|
||||
// Pre-generate order ID so items can reference it in the same batch
|
||||
// PocketBase accepts custom IDs (15-char alphanumeric)
|
||||
const orderId = crypto.randomUUID().replaceAll('-', '').slice(0, 15);
|
||||
|
||||
// Queue order creation with known ID
|
||||
batch.collection('orders').create({ ...order, id: orderId });
|
||||
|
||||
// Queue all items referencing the pre-generated order ID
|
||||
items.forEach(item => {
|
||||
batch.collection('order_items').create({
|
||||
...item,
|
||||
order: orderId
|
||||
});
|
||||
});
|
||||
|
||||
// Execute atomically
|
||||
const results = await batch.send();
|
||||
// All succeed or all fail together
|
||||
|
||||
return {
|
||||
order: results[0],
|
||||
items: results.slice(1)
|
||||
};
|
||||
}
|
||||
|
||||
// Batch updates
|
||||
async function updatePrices(products) {
|
||||
const batch = pb.createBatch();
|
||||
|
||||
products.forEach(product => {
|
||||
batch.collection('products').update(product.id, {
|
||||
price: product.newPrice
|
||||
});
|
||||
});
|
||||
|
||||
const results = await batch.send();
|
||||
// 1 API call, atomic
|
||||
return results;
|
||||
}
|
||||
|
||||
// Batch upsert (create or update)
|
||||
async function syncProducts(products) {
|
||||
const batch = pb.createBatch();
|
||||
|
||||
products.forEach(product => {
|
||||
batch.collection('products').upsert({
|
||||
id: product.sku, // Use SKU as ID for upsert matching
|
||||
name: product.name,
|
||||
price: product.price,
|
||||
stock: product.stock
|
||||
});
|
||||
});
|
||||
|
||||
return batch.send();
|
||||
}
|
||||
|
||||
// Mixed operations in transaction
|
||||
// NOTE: Batch operations respect API rules per-operation, but ensure your
|
||||
// business logic validates inputs (e.g., sufficient balance) server-side
|
||||
// via hooks or API rules to prevent unauthorized transfers.
|
||||
async function transferFunds(fromId, toId, amount) {
|
||||
const batch = pb.createBatch();
|
||||
|
||||
batch.collection('accounts').update(fromId, { 'balance-': amount });
|
||||
batch.collection('accounts').update(toId, { 'balance+': amount });
|
||||
|
||||
// Create audit record
|
||||
batch.collection('transfers').create({
|
||||
from: fromId,
|
||||
to: toId,
|
||||
amount,
|
||||
timestamp: new Date()
|
||||
});
|
||||
|
||||
// All three operations atomic
|
||||
const [fromAccount, toAccount, transfer] = await batch.send();
|
||||
return { fromAccount, toAccount, transfer };
|
||||
}
|
||||
|
||||
// Batch delete
|
||||
async function deletePostWithComments(postId) {
|
||||
// First get comment IDs
|
||||
const comments = await pb.collection('comments').getFullList({
|
||||
filter: pb.filter('post = {:postId}', { postId }),
|
||||
fields: 'id'
|
||||
});
|
||||
|
||||
const batch = pb.createBatch();
|
||||
|
||||
// Queue all deletions
|
||||
comments.forEach(comment => {
|
||||
batch.collection('comments').delete(comment.id);
|
||||
});
|
||||
batch.collection('posts').delete(postId);
|
||||
|
||||
await batch.send();
|
||||
// Post and all comments deleted atomically
|
||||
}
|
||||
```
|
||||
|
||||
**Batch operation limits:**
|
||||
- **Must be enabled first** in Dashboard > Settings > Application (disabled by default; returns 403 otherwise)
|
||||
- Operations execute in a single database transaction
|
||||
- All succeed or all rollback
|
||||
- Respects API rules for each operation
|
||||
- Configurable limits: `maxRequests`, `timeout`, and `maxBodySize` (set in Dashboard)
|
||||
- **Avoid large file uploads** in batches over slow networks -- they block the entire transaction
|
||||
- Avoid custom hooks that call slow external APIs within batch operations
|
||||
|
||||
**When to use batch:**
|
||||
|
||||
| Scenario | Use Batch? |
|
||||
|----------|-----------|
|
||||
| Creating parent + children | Yes |
|
||||
| Bulk import/update | Yes |
|
||||
| Financial transactions | Yes |
|
||||
| Single record operations | No |
|
||||
| Independent operations | Optional |
|
||||

||||

|
||||
|
||||
## 3. Expand Relations Efficiently
|
||||
|
||||
**Impact: HIGH (Eliminates N+1 queries, reduces API calls by 90%+)**
|
||||
|
||||
Use the `expand` parameter to fetch related records in a single request. This eliminates N+1 query problems and dramatically reduces API calls.
|
||||
|
||||
**Incorrect (N+1 queries):**
|
||||
|
||||
```javascript
|
||||
// Fetching posts then authors separately - N+1 problem
|
||||
async function getPostsWithAuthors() {
|
||||
const posts = await pb.collection('posts').getList(1, 20);
|
||||
|
||||
// N additional requests for N posts!
|

return posts;
|

}
|

// 21 API calls for 20 posts!
|

|

// Even worse with multiple relations
|

**Correct (using expand):**
|
||||
|
||||
```javascript
|
||||
// Single request with expanded relations
|
||||
async function getPostsWithAuthors() {
|
||||
const posts = await pb.collection('posts').getList(1, 20, {

// Access expanded data
|

posts.items.forEach(post => {
|
||||
console.log('Author:', post.expand?.author?.name);
|
||||
});
|
||||
|
||||
return posts;
|
||||
}
|
||||
// 1 API call!
|
||||
|
||||
// Multiple relations
|
||||
async function getPostsWithAll() {
|
||||
const posts = await pb.collection('posts').getList(1, 20, {

expand: 'author,category,tags'

|

});
|

}
|

// Still just 1 API call!
|
||||
|
||||
// Nested expansion (up to 6 levels)
|
||||
async function getPostsWithNestedData() {
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
expand: 'author.profile,category.parent,comments_via_post.author'
|
||||
});
|
||||
|
||||
posts.items.forEach(post => {
|
||||
// Nested relations
|
||||
console.log('Author profile:', post.expand?.author?.expand?.profile);
|
||||
console.log('Parent category:', post.expand?.category?.expand?.parent);
|
||||
|
||||
// Back-relations (comments that reference this post)
|
||||
console.log('Comments:', post.expand?.['comments_via_post']);
|
||||
});
|
||||
}
|
||||
|
||||
// Back-relation expansion
|
||||
// If comments collection has a 'post' relation field pointing to posts
|
||||
async function getPostWithComments(postId) {
|
||||
const post = await pb.collection('posts').getOne(postId, {
|
||||
expand: 'comments_via_post,comments_via_post.author'
|
||||
});
|
||||
|
||||
// Access comments that reference this post
|
||||
const comments = post.expand?.['comments_via_post'] || [];
|
||||
comments.forEach(comment => {
|
||||
console.log(`${comment.expand?.author?.name}: ${comment.text}`);
|
||||
});
|
||||
|
||||
return post;
|
||||
}
|
||||
```
|
||||
|
||||
**Expand syntax:**
|
||||
|
||||
| Syntax | Description |
|
||||
|--------|-------------|
|
||||
| `expand: 'author'` | Single relation |
|
||||
| `expand: 'author,tags'` | Multiple relations |
|
||||
| `expand: 'author.profile'` | Nested relation (2 levels) |
|
||||
| `expand: 'comments_via_post'` | Back-relation (records pointing to this) |
|
||||
|
||||
**Handling optional expand data:**
|
||||
|
||||
```javascript
|
||||
// Always use optional chaining - expand may be undefined
|
||||
const authorName = post.expand?.author?.name || 'Unknown';
|
||||
|
||||
// Type-safe access with TypeScript
|
||||
interface Post {
|
||||
id: string;
|
||||
title: string;
|
||||
author: string; // Relation ID
|
||||
expand?: {
|
||||
author?: User;
|
||||
};
|
||||
}
|
||||
|
||||
const posts = await pb.collection('posts').getList<Post>(1, 20, {
|
||||
expand: 'author'
|
||||
});
|
||||
```
|
||||
|
||||
**Limitations:**
|
||||
- Maximum 6 levels of nesting
|
||||
- Respects API rules on expanded collections
|
||||
- Large expansions may impact performance

## 4. Select Only Required Fields
|
||||
|
||||
**Impact: MEDIUM (Reduces payload size, improves response time)**
|
||||
|
||||
Use the `fields` parameter to request only the data you need. This reduces bandwidth and can improve query performance, especially with large text or file fields.
|
||||
|
||||
**Incorrect (fetching everything):**
|
||||
|
||||
```javascript
|
||||
// Fetching all fields when only a few are needed
|
||||
const posts = await pb.collection('posts').getList(1, 20);
|
||||
// Returns: id, title, content (10KB), thumbnail, author, tags, created, updated...
|
||||
|
||||
// Only displaying titles in a list
|
||||
posts.items.forEach(post => {
|
||||
renderListItem(post.title); // Only using title!
|
||||
});
|
||||
// Wasted bandwidth on content, thumbnail URLs, etc.
|
||||
|
||||
// Fetching user data with large profile fields
|
||||
const users = await pb.collection('users').getFullList();
|
||||
// Includes: avatar (file), bio (text), settings (json)...
|
||||
// When you only need names for a dropdown
|
||||
```
|
||||
|
||||
**Correct (selecting specific fields):**
|
||||
|
||||
```javascript
|
||||
// Select only needed fields
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
fields: 'id,title,created'
|
||||
});
|
||||
// Returns only: { id, title, created }
|
||||
|
||||
// For a dropdown/autocomplete
|
||||
const users = await pb.collection('users').getFullList({
|
||||
fields: 'id,name,avatar'
|
||||
});
|
||||
|
||||
// Include expanded relation fields
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
expand: 'author',
|
||||
fields: 'id,title,expand.author.name,expand.author.avatar'
|
||||
});
|
||||
// Returns: { id, title, expand: { author: { name, avatar } } }
|
||||
|
||||
// Wildcard for all direct fields, specific for expand
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
expand: 'author,category',
|
||||
fields: '*,expand.author.name,expand.category.name'
|
||||
});
|
||||
// All post fields + only name from expanded relations
|
||||
```
|
||||
|
||||
**Using excerpt modifier:**
|
||||
|
||||
```javascript
|
||||
// Get truncated text content
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
fields: 'id,title,content:excerpt(200,true)'
|
||||
});
|
||||
// content is truncated to 200 chars with "..." appended
|
||||
|
||||
// Multiple excerpts
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
fields: 'id,title:excerpt(50),content:excerpt(150,true)'
|
||||
});
|
||||
|
||||
// Excerpt syntax: field:excerpt(maxLength, withEllipsis?)
|
||||
// - maxLength: maximum characters
|
||||
// - withEllipsis: append "..." if truncated (default: false)
|
||||
```
|
||||
|
||||
**Common field selection patterns:**
|
||||
|
||||
```javascript
|
||||
// List view - minimal data
|
||||
const listFields = 'id,title,thumbnail,author,created';
|
||||
|
||||
// Card view - slightly more
|
||||
const cardFields = 'id,title,content:excerpt(200,true),thumbnail,author,created';
|
||||
|
||||
// Detail view - most fields
|
||||
const detailFields = '*,expand.author.name,expand.author.avatar';
|
||||
|
||||
// Autocomplete - just id and display text
|
||||
const autocompleteFields = 'id,name';
|
||||
|
||||
// Table export - specific columns
|
||||
const exportFields = 'id,email,name,created,status';
|
||||
|
||||
// Usage
|
||||
async function getPostsList() {
|
||||
return pb.collection('posts').getList(1, 20, {
|
||||
fields: listFields,
|
||||
expand: 'author'
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Performance impact:**
|
||||
|
||||
| Field Type | Impact of Selecting |
|
||||
|------------|-------------------|
|
||||
| text/editor | High (can be large) |
|
||||
| file | Medium (URLs generated) |
|
||||
| json | Medium (can be large) |
|
||||
| relation | Low (just IDs) |
|
||||
| number/bool | Low |
|
||||
|
||||
**Note:** Field selection happens after data is fetched from database, so it primarily saves bandwidth, not database queries. For database-level optimization, ensure proper indexes.

|
||||
## 5. Use getFirstListItem for Single Record Lookups
|
||||
|
||||
**Impact: MEDIUM (Cleaner code, automatic error handling for not found)**
|
||||
|
||||
Use `getFirstListItem()` when you need to find a single record by a field value other than ID. It's cleaner than `getList()` with limit 1 and provides proper error handling.
|
||||
|
||||
**Incorrect (manual single-record lookup):**
|
||||
|
||||
```javascript
|
||||
// Using getList with limit 1 - verbose
|
||||
async function findUserByEmail(email) {
|
||||
const result = await pb.collection('users').getList(1, 1, {
|
||||
filter: pb.filter('email = {:email}', { email })
|
||||
});
|
||||
|
||||
if (result.items.length === 0) {
|
||||
throw new Error('User not found');
|
||||
}
|
||||
|
||||
return result.items[0];
|
||||
}
|
||||
|
||||
// Using getFullList then filtering - wasteful
|
||||
async function findUserByUsername(username) {
|
||||
const users = await pb.collection('users').getFullList({
|
||||
filter: pb.filter('username = {:username}', { username })
|
||||
});
|
||||
return users[0]; // Might be undefined!
|
||||
}
|
||||
|
||||
// Fetching by ID when you have a different identifier
|
||||
async function findProductBySku(sku) {
|
||||
// Wrong: getOne expects the record ID
|
||||
const product = await pb.collection('products').getOne(sku); // Fails!
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using getFirstListItem):**
|
||||
|
||||
```javascript
|
||||
// Clean single-record lookup by any field
|
||||
async function findUserByEmail(email) {
|
||||
try {
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
pb.filter('email = {:email}', { email })
|
||||
);
|
||||
return user;
|
||||
} catch (error) {
|
||||
if (error.status === 404) {
|
||||
return null; // Not found
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Lookup by unique field
|
||||
async function findProductBySku(sku) {
|
||||
return pb.collection('products').getFirstListItem(
|
||||
pb.filter('sku = {:sku}', { sku })
|
||||
);
|
||||
}
|
||||
|
||||
// Lookup with expand
|
||||
async function findOrderByNumber(orderNumber) {
|
||||
return pb.collection('orders').getFirstListItem(
|
||||
pb.filter('orderNumber = {:num}', { num: orderNumber }),
|
||||
{ expand: 'customer,items' }
|
||||
);
|
||||
}
|
||||
|
||||
// Complex filter conditions
|
||||
async function findActiveSubscription(userId) {
|
||||
return pb.collection('subscriptions').getFirstListItem(
|
||||
pb.filter(
|
||||
'user = {:userId} && status = "active" && expiresAt > @now',
|
||||
{ userId }
|
||||
)
|
||||
);
|
||||
}
|
||||
|
||||
// With field selection
|
||||
async function getUserIdByEmail(email) {
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
pb.filter('email = {:email}', { email }),
|
||||
{ fields: 'id' }
|
||||
);
|
||||
return user.id;
|
||||
}
|
||||
```
|
||||
|
||||
**Comparison with getOne:**
|
||||
|
||||
```javascript
|
||||
// getOne - fetch by record ID
|
||||
const post = await pb.collection('posts').getOne('abc123');
|
||||
|
||||
// getFirstListItem - fetch by any filter (use pb.filter for safe binding)
|
||||
const post = await pb.collection('posts').getFirstListItem(
|
||||
pb.filter('slug = {:slug}', { slug: 'hello-world' })
|
||||
);
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
pb.filter('username = {:name}', { name: 'john' })
|
||||
);
|
||||
const order = await pb.collection('orders').getFirstListItem(
|
||||
pb.filter('orderNumber = {:num}', { num: 12345 })
|
||||
);
|
||||
```
|
||||
|
||||
**Error handling:**
|
||||
|
||||
```javascript
|
||||
// getFirstListItem throws 404 if no match found
|
||||
try {
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
pb.filter('email = {:email}', { email })
|
||||
);
|
||||
return user;
|
||||
} catch (error) {
|
||||
if (error.status === 404) {
|
||||
// No matching record - handle appropriately
|
||||
return null;
|
||||
}
|
||||
// Other error (network, auth, etc.)
|
||||
throw error;
|
||||
}
|
||||
|
||||
// Wrapper function for optional lookup
|
||||
async function findFirst(collection, filter, options = {}) {
|
||||
try {
|
||||
return await pb.collection(collection).getFirstListItem(filter, options);
|
||||
} catch (error) {
|
||||
if (error.status === 404) return null;
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
const user = await findFirst('users', pb.filter('email = {:e}', { e: email }));
|
||||
if (!user) {
|
||||
console.log('User not found');
|
||||
}
|
||||
```
|
||||
|
||||
**When to use each method:**
|
||||
|
||||
| Method | Use When |
|
||||
|--------|----------|
|
||||
| `getOne(id)` | You have the record ID |
|
||||
| `getFirstListItem(filter)` | Finding by unique field (email, slug, sku) |
|
||||
| `getList(1, 1, { filter })` | Need pagination metadata |
|
||||
| `getFullList({ filter })` | Expecting multiple results |

|
||||
## 6. Prevent N+1 Query Problems
|
||||
|
||||
**Impact: HIGH (Reduces API calls from N+1 to 1-2, dramatically faster page loads)**
|
||||
|
||||
N+1 queries occur when you fetch a list of records, then make additional requests for each record's related data. This pattern causes severe performance issues at scale.
|
||||
|
||||
**Incorrect (N+1 patterns):**
|
||||
|
||||
```javascript
|
||||
// Classic N+1: fetching related data in a loop
|
||||
async function getPostsWithDetails() {
|
||||
const posts = await pb.collection('posts').getList(1, 20); // 1 query
|
||||
|
||||
for (const post of posts.items) {
|
||||
// N additional queries!
|
||||
post.author = await pb.collection('users').getOne(post.author);
|
||||
post.category = await pb.collection('categories').getOne(post.category);
|
||||
}
|
||||
// Total: 1 + 20 + 20 = 41 queries for 20 posts
|
||||
}
|
||||
|
||||
// N+1 with Promise.all (faster but still N+1)
|
||||
async function getPostsParallel() {
|
||||
const posts = await pb.collection('posts').getList(1, 20);
|
||||
|
||||
await Promise.all(posts.items.map(async post => {
|
||||
post.author = await pb.collection('users').getOne(post.author);
|
||||
}));
|
||||
// Still 21 API calls, just parallel
|
||||
}
|
||||
|
||||
// Hidden N+1 in rendering
|
||||
function PostList({ posts }) {
|
||||
return posts.map(post => (
|
||||
<PostCard
|
||||
post={post}
|
||||
author={useAuthor(post.author)} // Each triggers a fetch!
|
||||
/>
|
||||
));
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (eliminate N+1):**
|
||||
|
||||
```javascript
|
||||
// Solution 1: Use expand for relations
|
||||
async function getPostsWithDetails() {
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
expand: 'author,category,tags'
|
||||
});
|
||||
|
||||
// All data in one request
|
||||
posts.items.forEach(post => {
|
||||
console.log(post.expand?.author?.name);
|
||||
console.log(post.expand?.category?.name);
|
||||
});
|
||||
// Total: 1 query
|
||||
}
|
||||
|
||||
// Solution 2: Batch fetch related records
|
||||
async function getPostsWithAuthorsBatch() {
|
||||
const posts = await pb.collection('posts').getList(1, 20);
|
||||
|
||||
// Collect unique author IDs
|
||||
const authorIds = [...new Set(posts.items.map(p => p.author))];
|
||||
|
||||
// Single query for all authors (use pb.filter for safe binding)
|
||||
const filter = authorIds.map(id => pb.filter('id = {:id}', { id })).join(' || ');
|
||||
const authors = await pb.collection('users').getList(1, authorIds.length, {
|
||||
filter
|
||||
});
|
||||
|
||||
// Create lookup map
|
||||
const authorMap = Object.fromEntries(
|
||||
authors.items.map(a => [a.id, a])
|
||||
);
|
||||
|
||||
// Attach to posts
|
||||
posts.items.forEach(post => {
|
||||
post.authorData = authorMap[post.author];
|
||||
});
|
||||
// Total: 2 queries regardless of post count
|
||||
}
|
||||
|
||||
// Solution 3: Use view collection for complex joins
|
||||
// Create a view that joins posts with authors:
|
||||
// SELECT p.*, u.name as author_name, u.avatar as author_avatar
|
||||
// FROM posts p LEFT JOIN users u ON p.author = u.id
|
||||
|
||||
async function getPostsFromView() {
|
||||
const posts = await pb.collection('posts_with_authors').getList(1, 20);
|
||||
// Single query, data already joined
|
||||
}
|
||||
|
||||
// Solution 4: Back-relations with expand
|
||||
async function getUserWithPosts(userId) {
|
||||
const user = await pb.collection('users').getOne(userId, {
|
||||
expand: 'posts_via_author' // All posts by this user
|
||||
});
|
||||
|
||||
console.log('Posts by user:', user.expand?.posts_via_author);
|
||||
// 1 query gets user + all their posts
|
||||
}
|
||||
```
|
||||
|
||||
**Detecting N+1 in your code:**
|
||||
|
||||
```javascript
|
||||
// Add request logging to detect N+1
|
||||
let requestCount = 0;
|
||||
pb.beforeSend = (url, options) => {
|
||||
requestCount++;
|
||||
console.log(`Request #${requestCount}: ${options.method} ${url}`);
|
||||
return { url, options };
|
||||
};
|
||||
|
||||
// Monitor during development
|
||||
async function loadPage() {
|
||||
requestCount = 0;
|
||||
await loadAllData();
|
||||
console.log(`Total requests: ${requestCount}`);
|
||||
// If this is >> number of records, you have N+1
|
||||
}
|
||||
```
|
||||
|
||||
**Prevention checklist:**
|
||||
- [ ] Always use `expand` for displaying related data
|
||||
- [ ] Never fetch related records in loops
|
||||
- [ ] Batch fetch when expand isn't available
|
||||
- [ ] Consider view collections for complex joins
|
||||
- [ ] Monitor request counts during development

## 7. Use Efficient Pagination Strategies
|
||||
|
||||
**Impact: HIGH (10-100x faster list queries on large collections)**
|
||||
|
||||
Pagination impacts performance significantly. Use `skipTotal` for large datasets, cursor-based pagination for infinite scroll, and appropriate page sizes.
|
||||
|
||||
**Incorrect (inefficient pagination):**
|
||||
|
||||
```javascript
|
||||
// Fetching all records - memory and performance disaster
|
||||
const allPosts = await pb.collection('posts').getFullList();
|
||||
// Downloads entire table, crashes on large datasets
|
||||
|
||||
// Default pagination without skipTotal
|
||||
const posts = await pb.collection('posts').getList(100, 20);
|
||||
// COUNT(*) runs on every request - slow on large tables
|
||||
|
||||
// Using offset for infinite scroll
|
||||
async function loadMore(page) {
|
||||
// As page increases, offset queries get slower
|
||||
return pb.collection('posts').getList(page, 20);
|
||||
// Page 1000: skips 19,980 rows before returning 20
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (optimized pagination):**
|
||||
|
||||
```javascript
|
||||
// Use skipTotal for better performance on large collections
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
skipTotal: true, // Skip COUNT(*) query
|
||||
sort: '-created'
|
||||
});
|
||||
// Returns items without totalItems/totalPages (faster)
|
||||
|
||||
// Cursor-based pagination for infinite scroll
|
||||
async function loadMorePosts(lastCreated = null) {
|
||||
const filter = lastCreated
|
||||
? pb.filter('created < {:cursor}', { cursor: lastCreated })
|
||||
: '';
|
||||
|
||||
const result = await pb.collection('posts').getList(1, 20, {
|
||||
filter,
|
||||
sort: '-created',
|
||||
skipTotal: true
|
||||
});
|
||||
|
||||
// Next cursor is the last item's created date
|
||||
const nextCursor = result.items.length > 0
|
||||
? result.items[result.items.length - 1].created
|
||||
: null;
|
||||
|
||||
return { items: result.items, nextCursor };
|
||||
}
|
||||
|
||||
// Usage for infinite scroll
|
||||
let cursor = null;
|
||||
async function loadNextPage() {
|
||||
const { items, nextCursor } = await loadMorePosts(cursor);
|
||||
cursor = nextCursor;
|
||||
appendToList(items);
|
||||
}
|
||||
|
||||
// Batched fetching when you need all records
|
||||
async function getAllPostsEfficiently() {
|
||||
const allPosts = [];
|
||||
let page = 1;
|
||||
const perPage = 1000; // Larger batches = fewer requests (max 1000 per API limit)
|
||||
|
||||
while (true) {
|
||||
const result = await pb.collection('posts').getList(page, perPage, {
|
||||
skipTotal: true
|
||||
});
|
||||
|
||||
allPosts.push(...result.items);
|
||||
|
||||
if (result.items.length < perPage) {
|
||||
break; // No more records
|
||||
}
|
||||
page++;
|
||||
}
|
||||
|
||||
return allPosts;
|
||||
}
|
||||
|
||||
// Or use getFullList with batch option
|
||||
const allPosts = await pb.collection('posts').getFullList({
|
||||
batch: 1000, // Records per request (default 1000 since JS SDK v0.26.6; max 1000)
|
||||
sort: '-created'
|
||||
});
|
||||
```
|
||||
|
||||
**Choose the right approach:**
|
||||
|
||||
| Use Case | Approach |
|
||||
|----------|----------|
|
||||
| Standard list with page numbers | `getList()` with page/perPage |
|
||||
| Large dataset, no total needed | `getList()` with `skipTotal: true` |
|
||||
| Infinite scroll | Cursor-based with `skipTotal: true` |
|
||||
| Export all data | `getFullList()` with batch size |
|
||||
| First N records only | `getList(1, N, { skipTotal: true })` |
|
||||
|
||||
**Performance tips:**
|
||||
- Use `skipTotal: true` unless you need page count
|
||||
- Keep `perPage` reasonable (20-100 for UI, up to 1000 for batch exports)
|
||||
- Index fields used in sort and filter
|
||||
- Cursor pagination scales better than offset

# Realtime
|
||||
|
||||
**Impact: MEDIUM**
|
||||
|
||||
SSE subscriptions, event handling, connection management, and authentication with realtime.
|
||||
|
||||
---
|
||||
|
||||
## 1. Authenticate Realtime Connections
|
||||
|
||||
**Impact: MEDIUM (Secure subscriptions respecting API rules)**
|
||||
|
||||
Realtime subscriptions respect collection API rules. Ensure the connection is authenticated before subscribing to protected data.
|
||||
|
||||
**Incorrect (subscribing without auth context):**
|
||||
|
||||
```javascript
|
||||
// Subscribing before authentication
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// This will fail or return no data if collection requires auth
|
||||
pb.collection('private_messages').subscribe('*', (e) => {
|
||||
// Won't receive events - not authenticated!
|
||||
console.log(e.record);
|
||||
});
|
||||
|
||||
// Later user logs in, but subscription doesn't update
|
||||
await pb.collection('users').authWithPassword(email, password);
|
||||
// Existing subscription still unauthenticated!
|
||||
```
|
||||
|
||||
**Correct (authenticated subscriptions):**
|
||||
|
||||
```javascript
|
||||
// Subscribe after authentication
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
async function initRealtime() {
|
||||
// First authenticate
|
||||
await pb.collection('users').authWithPassword(email, password);
|
||||
|
||||
// Now subscribe - will use auth context
|
||||
pb.collection('private_messages').subscribe('*', (e) => {
|
||||
// Receives events for messages user can access
|
||||
console.log('New message:', e.record);
|
||||
});
|
||||
}
|
||||
|
||||
// Re-subscribe after auth changes
|
||||
function useAuthenticatedRealtime() {
|
||||
const [messages, setMessages] = useState([]);
|
||||
const unsubRef = useRef(null);
|
||||
|
||||
// Watch auth changes
|
||||
useEffect(() => {
|
||||
const removeListener = pb.authStore.onChange((token, record) => {
|
||||
// Unsubscribe old connection
|
||||
if (unsubRef.current) {
|
||||
unsubRef.current();
|
||||
unsubRef.current = null;
|
||||
}
|
||||
|
||||
// Re-subscribe with new auth context if logged in
|
||||
if (record) {
|
||||
setupSubscription();
|
||||
} else {
|
||||
setMessages([]);
|
||||
}
|
||||
}, true);
|
||||
|
||||
return () => {
|
||||
removeListener();
|
||||
if (unsubRef.current) unsubRef.current();
|
||||
};
|
||||
}, []);
|
||||
|
||||
async function setupSubscription() {
|
||||
unsubRef.current = await pb.collection('private_messages').subscribe('*', (e) => {
|
||||
handleMessage(e);
|
||||
});
|
||||
}
|
||||
}
|
||||
|
||||
// Handle auth token refresh with realtime
|
||||
pb.realtime.subscribe('PB_CONNECT', async (e) => {
|
||||
console.log('Realtime connected');
|
||||
|
||||
// Verify auth is still valid
|
||||
if (pb.authStore.isValid) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
// Redirect to login
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**API rules apply to subscriptions:**
|
||||
|
||||
```javascript
|
||||
// Collection rule: listRule: 'owner = @request.auth.id'
|
||||
|
||||
// User A subscribed
|
||||
await pb.collection('users').authWithPassword('a@test.com', 'password');
|
||||
pb.collection('notes').subscribe('*', handler);
|
||||
// Only receives events for notes where owner = User A
|
||||
|
||||
// Events from other users' notes are filtered out automatically
|
||||
```
|
||||
|
||||
**Subscription authorization flow:**
|
||||
|
||||
1. SSE connection established (no auth check)
|
||||
2. First subscription triggers authorization
|
||||
3. Auth token from `pb.authStore` is used
|
||||
4. Collection rules evaluated for each event
|
||||
5. Only matching events sent to client
|
||||
|
||||
**Handling auth expiration:**
|
||||
|
||||
```javascript
|
||||
// Setup disconnect handler
|
||||
pb.realtime.onDisconnect = (subscriptions) => {
|
||||
console.log('Disconnected, had subscriptions:', subscriptions);
|
||||
|
||||
// Check if auth expired
|
||||
if (!pb.authStore.isValid) {
|
||||
// Token expired - need to re-authenticate
|
||||
redirectToLogin();
|
||||
return;
|
||||
}
|
||||
|
||||
// Connection issue - realtime will auto-reconnect
|
||||
// Re-subscribe after reconnection
|
||||
pb.realtime.subscribe('PB_CONNECT', () => {
|
||||
resubscribeAll(subscriptions);
|
||||
});
|
||||
};
|
||||
|
||||
function resubscribeAll(subscriptions) {
|
||||
subscriptions.forEach(sub => {
|
||||
const [collection, topic] = sub.split('/');
|
||||
pb.collection(collection).subscribe(topic, handlers[sub]);
|
||||
});
|
||||
}
|
||||
```

|
||||
|
||||
## 2. Handle Realtime Events Properly
|
||||
|
||||
**Impact: MEDIUM (Consistent UI state, proper optimistic updates)**
|
||||
|
||||
Realtime events should update local state correctly, handle edge cases, and maintain UI consistency.
|
||||
|
||||
**Incorrect (naive event handling):**
|
||||
|
||||
```javascript
|
||||
// Blindly appending creates - may add duplicates
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
if (e.action === 'create') {
|
||||
posts.push(e.record); // Might already exist from optimistic update!
|
||||
}
|
||||
});
|
||||
|
||||
// Not handling own actions
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
// User creates post -> optimistic update
|
||||
// Realtime event arrives -> duplicate!
|
||||
setPosts(prev => [...prev, e.record]);
|
||||
});
|
||||
|
||||
// Missing action types
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
if (e.action === 'create') handleCreate(e);
|
||||
// Ignoring update and delete!
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (robust event handling):**
|
||||
|
||||
```javascript
|
||||
// Handle all action types with deduplication
|
||||
function useRealtimePosts() {
|
||||
const [posts, setPosts] = useState([]);
|
||||
const pendingCreates = useRef(new Set());
|
||||
|
||||
useEffect(() => {
|
||||
loadPosts();
|
||||
|
||||
const unsub = pb.collection('posts').subscribe('*', (e) => {
|
||||
switch (e.action) {
|
||||
case 'create':
|
||||
// Skip if we created it (optimistic update already applied)
|
||||
if (pendingCreates.current.has(e.record.id)) {
|
||||
pendingCreates.current.delete(e.record.id);
|
||||
return;
|
||||
}
|
||||
setPosts(prev => {
|
||||
// Deduplicate - might already exist
|
||||
if (prev.some(p => p.id === e.record.id)) return prev;
|
||||
return [e.record, ...prev];
|
||||
});
|

break;
|

break;
|

}
|
||||
});
|

const optimisticPost = { ...data, id: tempId };
|
||||
setPosts(prev => [optimisticPost, ...prev]);
|
||||
|
||||
try {
|
||||
const created = await pb.collection('posts').create(data);
|
||||
// Mark as pending so realtime event is ignored
|
||||
pendingCreates.current.add(created.id);
|
||||
// Replace optimistic with real
|
||||
setPosts(prev => prev.map(p =>
|
||||
p.id === tempId ? created : p
|
||||
));
|
||||
return created;
|
||||
} catch (error) {
|
||||
// Rollback optimistic update
|
||||
setPosts(prev => prev.filter(p => p.id !== tempId));
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
return { posts, createPost };
|
||||
}
|
||||
|
||||
// Batched updates for high-frequency changes
|
||||
function useRealtimeWithBatching() {
|
||||
const [posts, setPosts] = useState([]);
|
||||
const pendingUpdates = useRef([]);
|

const flushTimeout = useRef(null);
|

useEffect(() => {
|

const unsub = pb.collection('posts').subscribe('*', (e) => {
|
||||
pendingUpdates.current.push(e);
|
||||
|
||||
// Batch updates every 100ms
|
||||
if (!flushTimeout.current) {
|
||||
flushTimeout.current = setTimeout(() => {

}, 100);
|

next = next.filter(p => p.id !== e.record.id);
|
||||
}
|
||||
}
|
||||
return next;
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Filtering events:**
|
||||
|
||||
```javascript
|
||||
// Only handle events matching certain criteria
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
// Only published posts
|
||||
if (e.record.status !== 'published') return;
|
||||
|
||||
// Only posts by current user
|
||||
if (e.record.author !== pb.authStore.record?.id) return;
|
||||
|
||||
handleEvent(e);
|
||||
});
|
||||
|
||||
// Subscribe with expand to get related data
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
// Note: expand data is included in realtime events
|
||||
// if the subscription options include expand
|
||||
console.log(e.record.expand?.author?.name);
|
||||
}, { expand: 'author' });
|

```

|
||||
## 3. Handle Realtime Connection Issues
|
||||
|
||||
**Impact: MEDIUM (Reliable realtime even with network interruptions)**
|
||||
|
||||
Realtime connections can disconnect due to network issues or server restarts. Implement proper reconnection handling and state synchronization.
|
||||
|
||||
**Incorrect (ignoring connection issues):**
|
||||
|
||||
```javascript
|
||||
// No reconnection handling - stale data after disconnect
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
updateUI(e.record);
|
||||
});
|
||||
// If connection drops, UI shows stale data indefinitely
|
||||
|
||||
// Assuming connection is always stable
|
||||
function PostList() {
|
||||
useEffect(() => {
|
||||
pb.collection('posts').subscribe('*', handleChange);
|
||||
}, []);
|
||||
// No awareness of connection state
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (robust connection handling):**
|
||||
|
||||
```javascript
|
||||
// Monitor connection state
|
||||
function useRealtimeConnection() {
|
||||
const [connected, setConnected] = useState(false);
|
||||
const [lastSync, setLastSync] = useState(null);
|
||||
|
||||
useEffect(() => {
|
||||
// Track connection state
|
||||
const unsubConnect = pb.realtime.subscribe('PB_CONNECT', (e) => {
|
||||
console.log('Connected, client ID:', e.clientId);
|
||||
setConnected(true);
|
||||
|
||||
// Re-sync data after reconnection
|
||||
if (lastSync) {
|
||||
syncMissedUpdates(lastSync);
|
||||
}
|
||||
setLastSync(new Date());
|

async function syncMissedUpdates(since) {
|
||||
// Fetch records modified since last sync
|
||||
const updatedPosts = await pb.collection('posts').getList(1, 100, {
|

this.maxReconnectDelay
|

);

// Notify subscribers of missed updates
|
||||
const handler = this.subscriptions.get(collection);
|
||||
if (handler) {
|
||||
updates.items.forEach(record => {
|
||||
handler({ action: 'update', record });
|
||||
});
|

}
|
||||
|

this.lastSyncTimes.set(collection, new Date());
|
||||
} catch (error) {
|
||||
console.error(`Failed to sync ${collection}:`, error);
|

}
|

}
|

async subscribe(collection, handler) {
|

|
||||
|
||||
return this.pb.collection(collection).subscribe('*', (e) => {

|
||||
} catch {
|
||||
this.pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
|
||||
for (const [collection, handler] of this.subscriptions) {
|
||||
this.pb.collection(collection).subscribe('*', handler);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
const realtime = new RealtimeManager(pb);
|
||||
await realtime.subscribe('posts', handlePostChange);
|
||||
```
|
||||
|
||||
**Connection timeout handling:**
|
||||
|
||||
```javascript
|
||||
// Server sends disconnect after 5 min of no messages
|
||||
// SDK auto-reconnects, but you can handle it explicitly
|
||||
|
||||
let lastHeartbeat = Date.now();
|
||||
|
||||
pb.realtime.subscribe('PB_CONNECT', () => {
|
||||
lastHeartbeat = Date.now();
|
||||
});
|
||||
|
||||
// Check for stale connection
|
||||
setInterval(() => {
|
||||
if (Date.now() - lastHeartbeat > 6 * 60 * 1000) {
|
||||
console.log('Connection may be stale, refreshing...');
|
||||
pb.realtime.unsubscribe();
|
||||
resubscribeAll();
|
||||
}
|
||||
}, 60000);
|
||||
```

|
||||
## 4. Implement Realtime Subscriptions Correctly
|
||||
|
||||
**Impact: MEDIUM (Live updates without polling, reduced server load)**
|
||||
|
||||
PocketBase uses Server-Sent Events (SSE) for realtime updates. Proper subscription management prevents memory leaks and ensures reliable event delivery.
|
||||
|
||||
**Incorrect (memory leaks and poor management):**
|
||||
|
||||
```javascript
|
||||
// Missing unsubscribe - memory leak!
|
||||
function PostList() {
|
||||
useEffect(() => {
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
updatePosts(e);
|
||||
});
|
||||
// No cleanup - subscription persists forever!
|
||||
}, []);
|
||||
}
|
||||
|
||||
// Subscribing multiple times
|
||||
function loadPosts() {
|
||||
// Called on every render - creates duplicate subscriptions!
|
||||
pb.collection('posts').subscribe('*', handleChange);
|
||||
}
|
||||
|
||||
// Not handling reconnection
|
||||
pb.collection('posts').subscribe('*', (e) => {
|
||||
// Assumes connection is always stable
|
||||
updateUI(e);
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (proper subscription management):**
|
||||
|
||||
```javascript
|
||||
// React example with cleanup
|
||||
function PostList() {
|
||||
const [posts, setPosts] = useState([]);
|
||||
|
||||
useEffect(() => {
|
||||
// Initial load
|
||||
loadPosts();
|
||||
|
||||
// Subscribe to changes
|
||||
const unsubscribe = pb.collection('posts').subscribe('*', (e) => {
|
||||
if (e.action === 'create') {
|
||||
setPosts(prev => [e.record, ...prev]);
|
||||
} else if (e.action === 'update') {
|
||||
setPosts(prev => prev.map(p =>
|
||||
p.id === e.record.id ? e.record : p
|
||||
));
|
||||
} else if (e.action === 'delete') {
|
||||
setPosts(prev => prev.filter(p => p.id !== e.record.id));
|
||||
}
|
||||
});
|
||||
|
||||
// Cleanup on unmount
|
||||
return () => {
|
||||
unsubscribe();
|
||||
};
|
||||
}, []);
|
||||
|
||||
async function loadPosts() {
|
||||
const result = await pb.collection('posts').getList(1, 50);
|
||||
setPosts(result.items);
|
||||
}
|
||||
|
||||
return <PostListUI posts={posts} />;
|
||||
}
|
||||
|
||||
// Subscribe to specific record
|
||||
async function watchPost(postId) {
|
||||
return pb.collection('posts').subscribe(postId, (e) => {
|
||||
console.log('Post changed:', e.action, e.record);
|
||||
});
|
||||
}
|
||||
|
||||
// Subscribe to collection changes
|
||||
async function watchAllPosts() {
|
||||
return pb.collection('posts').subscribe('*', (e) => {
|
||||
console.log(`Post ${e.action}:`, e.record.title);
|
||||
});
|
||||
}
|
||||
|
||||
// Handle connection events
|
||||
pb.realtime.subscribe('PB_CONNECT', (e) => {
|
||||
console.log('Realtime connected, client ID:', e.clientId);
|
||||
// Re-sync data after reconnection
|
||||
refreshData();
|
||||
});
|
||||
|
||||
// Vanilla JS with proper cleanup
|
||||
class PostManager {
|
||||
unsubscribes = [];
|
||||
|
||||
async init() {
|
||||
this.unsubscribes.push(
|
||||
await pb.collection('posts').subscribe('*', this.handlePostChange)
|
||||
);
|
||||
this.unsubscribes.push(
|
||||
await pb.collection('comments').subscribe('*', this.handleCommentChange)
|
||||
);
|
||||
}
|
||||
|
||||
destroy() {
|
||||
this.unsubscribes.forEach(unsub => unsub());
|
||||
this.unsubscribes = [];
|
||||
}
|
||||
|
||||
handlePostChange = (e) => { /* ... */ };
|
||||
handleCommentChange = (e) => { /* ... */ };
|
||||
}
|
||||
```
|
||||
|
||||
**Subscription event structure:**
|
||||
|
||||
```javascript
|
||||
pb.collection('posts').subscribe('*', (event) => {
|
||||
event.action; // 'create' | 'update' | 'delete'
|
||||
event.record; // The affected record
|
||||
});
|
||||
|
||||
// Full event type
|
||||
interface RealtimeEvent {
|
||||
action: 'create' | 'update' | 'delete';
|
||||
record: RecordModel;
|
||||
}
|
||||
```
|
||||
|
||||
**Unsubscribe patterns:**
|
||||
|
||||
```javascript
|
||||
// Unsubscribe from specific callback
|
||||
const unsub = await pb.collection('posts').subscribe('*', callback);
|
||||
unsub(); // Remove this specific subscription
|
||||
|
||||
// Unsubscribe from all subscriptions on a topic
|
||||
pb.collection('posts').unsubscribe('*'); // All collection subs
|
||||
pb.collection('posts').unsubscribe('RECORD_ID'); // Specific record
|
||||
|
||||
// Unsubscribe from all collection subscriptions
|
||||
pb.collection('posts').unsubscribe();
|
||||
|
||||
// Unsubscribe from everything
|
||||
pb.realtime.unsubscribe();
|
||||
```
|
||||
|
||||
**Performance considerations:**
|
||||
|
||||
```javascript
|
||||
// Prefer specific record subscriptions over collection-wide when possible.
|
||||
// subscribe('*') checks ListRule for every connected client on each change.
|
||||
// subscribe(recordId) checks ViewRule -- fewer records to evaluate.
|
||||
|
||||
// For high-traffic collections, subscribe to specific records:
|
||||
await pb.collection('orders').subscribe(orderId, handleOrderUpdate);
|
||||
// Instead of: pb.collection('orders').subscribe('*', handleAllOrders);
|
||||
|
||||
// Use subscription options to reduce payload size (SDK v0.21+):
|
||||
await pb.collection('posts').subscribe('*', handleChange, {
|
||||
fields: 'id,title,updated', // Only receive specific fields
|
||||
expand: 'author', // Include expanded relations
|
||||
filter: 'status = "published"' // Only receive matching records
|
||||
});
|
||||
```
|
||||
|
||||
**Subscription scope guidelines:**
|
||||
|
||||
| Scenario | Recommended Scope |
|
||||
|----------|-------------------|
|
||||
| Watching a specific document | `subscribe(recordId)` |
|
||||
| Chat room messages | `subscribe('*')` with filter for room |
|
||||
| User notifications | `subscribe('*')` with filter for user |
|
||||
| Admin dashboard | `subscribe('*')` (need to see all) |
|
||||
| High-frequency data (IoT) | `subscribe(recordId)` per device |

title: Use Impersonation for Admin Operations
|
||||
impact: MEDIUM
|
||||
impactDescription: Safe admin access to user data without password sharing
|
||||
tags: authentication, admin, impersonation, superuser
|

---
|
||||
|
||||
## Use Impersonation for Admin Operations
|
||||
|
||||
Impersonation allows superusers to generate tokens for other users, enabling admin support tasks and API key functionality without sharing passwords.
|
||||
|
||||
**Incorrect (sharing credentials or bypassing auth):**
|
||||
|
||||
```javascript
|
||||
// Bad: sharing user passwords for support
|
||||
async function helpUser(userId, userPassword) {
|
||||
await pb.collection('users').authWithPassword(userEmail, userPassword);
|
||||
// Support team knows user's password!
|
||||
}
|
||||
|
||||
// Bad: directly modifying records without proper context
|
||||
async function fixUserData(userId) {
|
||||
// Bypasses user's perspective and rules
|
||||
await pb.collection('posts').update(postId, { fixed: true });
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using impersonation):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
// Admin client with superuser auth (use environment variables, never hardcode)
|
||||
const adminPb = new PocketBase(process.env.PB_URL);
|
||||
await adminPb.collection('_superusers').authWithPassword(
|
||||
process.env.PB_SUPERUSER_EMAIL,
|
||||
process.env.PB_SUPERUSER_PASSWORD
|
||||
);
|
||||
|
||||
async function impersonateUser(userId) {
|
||||
// Generate impersonation token (non-renewable)
|
||||
const impersonatedClient = await adminPb
|
||||
.collection('users')
|
||||
.impersonate(userId, 3600); // 1 hour duration
|
||||
|
||||
// impersonatedClient has user's auth context
|
||||
console.log('Acting as:', impersonatedClient.authStore.record.email);
|
||||
|
||||
// Operations use user's permissions
|
||||
const userPosts = await impersonatedClient.collection('posts').getList();
|
||||
|
||||
return impersonatedClient;
|
||||
}
|
||||
|
||||
// Use case: Admin viewing user's data
|
||||
async function adminViewUserPosts(userId) {
|
||||
const userClient = await impersonateUser(userId);
|
||||
|
||||
// See exactly what the user sees (respects API rules)
|
||||
const posts = await userClient.collection('posts').getList();
|
||||
|
||||
return posts;
|
||||
}
|
||||
|
||||
// Use case: API keys for server-to-server communication
|
||||
async function createApiKey(serviceUserId) {
|
||||
// Create a service impersonation token (use short durations, rotate regularly)
|
||||
const serviceClient = await adminPb
|
||||
.collection('service_accounts')
|
||||
.impersonate(serviceUserId, 86400); // 24 hours max, rotate via scheduled task
|
||||
|
||||
// Return token for service to use
|
||||
return serviceClient.authStore.token;
|
||||
}
|
||||
|
||||
// Using API key token in another service
|
||||
async function useApiKey(apiToken) {
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Manually set the token
|
||||
pb.authStore.save(apiToken, null);
|
||||
|
||||
// Now requests use the service account's permissions
|
||||
const data = await pb.collection('data').getList();
|
||||
return data;
|
||||
}
|
||||
```
|
||||
|
||||
**Important considerations:**
|
||||
|
||||
```javascript
|
||||
// Impersonation tokens are non-renewable
|
||||
const client = await adminPb.collection('users').impersonate(userId, 3600);
|
||||
|
||||
// This will fail - can't refresh impersonation tokens
|
||||
try {
|
||||
await client.collection('users').authRefresh();
|
||||
} catch (error) {
|
||||
// Expected: impersonation tokens can't be refreshed
|
||||
}
|
||||
|
||||
// For continuous access, generate new token when needed
|
||||
async function getImpersonatedClient(userId) {
|
||||
// Check if existing token is still valid
|
||||
if (cachedClient?.authStore.isValid) {
|
||||
return cachedClient;
|
||||
}
|
||||
|
||||
// Generate fresh token
|
||||
return await adminPb.collection('users').impersonate(userId, 3600);
|
||||
}
|
||||
```
|
||||
|
||||
**Security best practices:**
|
||||
- Use short durations for support tasks
|
||||
- Log all impersonation events
|
||||
- Restrict impersonation to specific admin roles
|
||||
- Never expose impersonation capability in client code
|
||||
- Use dedicated service accounts for API keys

title: Implement Multi-Factor Authentication

impactDescription: Additional security layer for sensitive applications
|
||||
tags: authentication, mfa, security, 2fa, otp
|
||||
---
|
||||
|
||||
## Implement Multi-Factor Authentication
|
||||
|
||||
MFA requires users to authenticate with two different methods. PocketBase supports OTP (One-Time Password) via email as the second factor.
|
||||
|
||||
**Incorrect (single-factor only for sensitive apps):**
|
||||
|
||||
```javascript
|
||||
// Insufficient for sensitive applications
|
||||
async function login(email, password) {
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
// User immediately has full access - no second factor
|
||||
return authData;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (MFA flow with OTP):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
async function loginWithMFA(email, password) {
|
||||
try {
|
||||
// First factor: password
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
|
||||
// If MFA not required, auth succeeds immediately
|
||||
return { success: true, authData };
|
||||
|
||||
} catch (error) {
|
||||
// MFA required - returns 401 with mfaId
|
||||
if (error.status === 401 && error.response?.mfaId) {
|
||||
return {
|
||||
success: false,
|
||||
mfaRequired: true,
|
||||
mfaId: error.response.mfaId
|
||||
};
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
async function requestOTP(email) {
|
||||
// Request OTP to be sent via email
|
||||
const result = await pb.collection('users').requestOTP(email);
|
||||
|
||||
// Returns otpId - needed to verify the OTP
|
||||
// Note: Returns otpId even if email doesn't exist (prevents enumeration)
|
||||
return result.otpId;
|
||||
}
|
||||
|
||||
async function completeMFAWithOTP(mfaId, otpId, otpCode) {
|
||||
try {
|
||||
// Second factor: OTP verification
|
||||
const authData = await pb.collection('users').authWithOTP(
|
||||
otpId,
|
||||
otpCode,
|
||||
{ mfaId } // Include mfaId from first factor
|
||||
);
|
||||
|
||||
return { success: true, authData };
|
||||
} catch (error) {
|
||||
if (error.status === 400) {
|
||||
throw new Error('Invalid or expired code');
|
||||
}
|
||||
throw error;
|
||||
}
|
||||

async function fullMFAFlow(email, password, otpCode = null) {

|
||||
const step1 = await loginWithMFA(email, password);
|
||||
|
||||

||||
|
||||
return { pendingMFA: true, mfaId: step1.mfaId, otpId };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Configure MFA (Admin UI or API):**
|
||||
|
||||
```javascript
|
||||
// Enable MFA on auth collection (superuser only)
|
||||
await pb.collections.update('users', {
|
||||
mfa: {
|
||||
enabled: true,
|
||||
duration: 1800, // MFA session duration (30 min)
|
||||
rule: '' // When to require MFA (empty = always for all users)
|
||||
// rule: '@request.auth.role = "admin"' // Only for admins
|
||||
},
|
||||
otp: {
|
||||
enabled: true,
|
||||
duration: 300, // OTP validity (5 min)
|
||||
length: 6, // OTP code length
|
||||
emailTemplate: {
|
||||
subject: 'Your verification code',
|
||||
body: 'Your code is: {OTP}'
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**MFA best practices:**
|
||||
- Always enable for admin accounts
|
||||
- Consider making MFA optional for regular users
|
||||
- Use short OTP durations (5-10 minutes)
|
||||
- Implement rate limiting on OTP requests
|
||||
- Log MFA events for security auditing

|

## Integrate OAuth2 Providers Correctly
|
||||
|
||||
OAuth2 integration should use the all-in-one method for simplicity and security. Manual code exchange should only be used when necessary (e.g., mobile apps with deep links).
|
||||
|
||||
**Incorrect (manual implementation without SDK):**
|
||||
|
||||
```javascript
|
||||
// Don't manually handle OAuth flow
|
||||
async function loginWithGoogle() {
|
||||
// Redirect user to Google manually
|
||||
window.location.href = 'https://accounts.google.com/oauth/authorize?...';
|
||||
}
|
||||
|
||||
// Manual callback handling
|
||||
async function handleCallback(code) {
|
||||
// Exchange code manually - error prone!
|
||||
const response = await fetch('/api/auth/callback', {
|
||||
method: 'POST',
|
||||
body: JSON.stringify({ code })
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using SDK's all-in-one method):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// All-in-one OAuth2 (recommended for web apps)
|
||||
async function loginWithOAuth2(providerName) {
|
||||
try {
|
||||
const authData = await pb.collection('users').authWithOAuth2({
|
||||
provider: providerName, // 'google', 'github', 'microsoft', etc.
|
||||
// Optional: create new user data if not exists
|
||||
createData: {
|
||||
emailVisibility: true,
|
||||
name: '' // Will be populated from OAuth provider
|
||||
}
|
||||
});
|
||||
|
||||
console.log('Logged in via', providerName);
|
||||
console.log('User:', authData.record.email);
|
||||
console.log('Is new user:', authData.meta?.isNew);
|
||||
|
||||
return authData;
|
||||
} catch (error) {
|
||||
if (error.isAbort) {
|
||||
console.log('OAuth popup was closed');
|
||||
return null;
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
document.getElementById('google-btn').onclick = () => loginWithOAuth2('google');
|
||||
document.getElementById('github-btn').onclick = () => loginWithOAuth2('github');
|
||||
```
|
||||
|
||||
**Manual code exchange (for React Native / deep links):**
|
||||
|
||||
```javascript
|
||||
// Only use when all-in-one isn't possible
|
||||
async function loginWithOAuth2Manual() {
|
||||
// Get auth methods - PocketBase provides state and codeVerifier
|
||||
const authMethods = await pb.collection('users').listAuthMethods();
|
||||
const provider = authMethods.oauth2.providers.find(p => p.name === 'google');
|
||||
|
||||
// Store the provider's state and codeVerifier for callback verification
|
||||
// PocketBase generates these for you - don't create your own
|
||||
sessionStorage.setItem('oauth_state', provider.state);
|
||||
sessionStorage.setItem('oauth_code_verifier', provider.codeVerifier);
|
||||
|
||||
// Build the OAuth URL using provider.authURL + redirect
|
||||
const redirectUrl = window.location.origin + '/oauth-callback';
|
||||
const authUrl = provider.authURL + encodeURIComponent(redirectUrl);
|
||||
|
||||
// Redirect to OAuth provider
|
||||
window.location.href = authUrl;
|
||||
}
|
||||
|
||||
// In your callback handler (e.g., /oauth-callback page):
|
||||
async function handleOAuth2Callback() {
|
||||
const params = new URLSearchParams(window.location.search);
|
||||
|
||||
// CSRF protection: verify state matches
|
||||
if (params.get('state') !== sessionStorage.getItem('oauth_state')) {
|
||||
throw new Error('State mismatch - potential CSRF attack');
|
||||
}
|
||||
|
||||
const code = params.get('code');
|
||||
const codeVerifier = sessionStorage.getItem('oauth_code_verifier');
|
||||
const redirectUrl = window.location.origin + '/oauth-callback';
|
||||
|
||||
// Exchange code for auth token
|
||||
const authData = await pb.collection('users').authWithOAuth2Code(
|
||||
'google',
|
||||
code,
|
||||
codeVerifier,
|
||||
redirectUrl,
|
||||
{ emailVisibility: true }
|
||||
);
|
||||
|
||||
// Clean up
|
||||
sessionStorage.removeItem('oauth_state');
|
||||
sessionStorage.removeItem('oauth_code_verifier');
|
||||
|
||||
return authData;
|
||||
}
|
||||
```
|
||||
|
||||
**Configure OAuth2 provider (Admin UI or API):**
|
||||
|
||||
```javascript
|
||||
// Via API (superuser only) - usually done in Admin UI
|
||||
// IMPORTANT: Never hardcode client secrets. Use environment variables.
|
||||
await pb.collections.update('users', {
|
||||
oauth2: {
|
||||
enabled: true,
|
||||
providers: [{
|
||||
name: 'google',
|
||||
clientId: process.env.GOOGLE_CLIENT_ID,
|
||||
clientSecret: process.env.GOOGLE_CLIENT_SECRET
|
||||
}],
|
||||
mappedFields: {
|
||||
avatarURL: 'avatar' // Map OAuth field to collection field
|

}
|
||||
}
|
||||
});
|

title: Use authWithOTP for Email One-Time Codes, Rate-Limit requestOTP
|
||||
impact: HIGH
|

impactDescription: OTP endpoints are unauthenticated; unthrottled requestOTP enables email bombing and enumeration

|
||||
|
||||
## Use authWithOTP for Email One-Time Codes, Rate-Limit requestOTP
|
||||
|
||||
Auth collections can enable **OTP login** from the admin UI (Collection → Options → "Enable OTP"). The client flow is two steps: `requestOTP(email)` returns an `otpId`, then `authWithOTP(otpId, code)` exchanges the id + code for an auth token. Two things trip people up: (1) the OTP response is **the same whether the email exists or not** - do not break that by leaking a distinct error; (2) `requestOTP` sends an email, so **it must be rate-limited** or an attacker can use it to spam any address.
|
||||
|
||||
**Incorrect (leaks existence, custom requestOTP with no rate limit):**
|
||||
|
||||
```javascript
|
||||
// ❌ Client-side existence check - ignore the 404 and expose it to the user
|
||||
try {
|
||||
await pb.collection("users").getFirstListItem(`email="${email}"`);
|
||||
} catch (e) {
|
||||
alert("No account with that email"); // ❌ account enumeration
|
||||
return;
|
||||
}
|
||||
|
||||
// ❌ Ad-hoc route with no rate limit - attacker hammers this to spam mailboxes
|
||||
routerAdd("POST", "/api/myapp/otp", (e) => {
|
||||
const body = e.requestInfo().body;
|
||||
const user = $app.findAuthRecordByEmail("users", body.email);
|
||||
// send custom email...
|
||||
return e.json(200, { ok: true });
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (use the built-in flow, step 1 always returns an otpId):**
|
||||
|
||||
```javascript
|
||||
// Step 1: request the code. Always returns { otpId } - even if the email
|
||||
// does not exist, PocketBase returns a synthetic id so enumeration is
|
||||
// impossible. Treat every response as success from the UI perspective.
|
||||
const { otpId } = await pb.collection("users").requestOTP("user@example.com");
|
||||
|
||||
// Step 2: exchange otpId + the 8-digit code the user typed
|
||||
const authData = await pb.collection("users").authWithOTP(
|
||||
otpId,
|
||||
"12345678",
|
||||
);
|
||||
// pb.authStore is now populated
|
||||
```
|
||||
|
||||
```go
|
||||
// Go side - rate-limit and log if you wrap your own endpoint
|
||||
app.OnRecordRequestOTPRequest("users").BindFunc(func(e *core.RecordRequestOTPRequestEvent) error {
|
||||
// e.Collection, e.Record (may be nil - synthetic id path),
|
||||
// e.Email (always present), e.Password (unused for OTP)
|
||||
e.App.Logger().Info("otp requested",
|
||||
"email", e.Email,
|
||||
"ip", e.RequestInfo.Headers["x_forwarded_for"])
|
||||
return e.Next() // REQUIRED
|
||||
})
|
||||
```
|
||||
|
||||
**Rules:**
|
||||
- `requestOTP` **always returns 200 with an otpId**, even for non-existent emails - preserve that by never adding a pre-check or a different error path.
|
||||
- Enable the built-in rate limiter (see `deploy-rate-limiting.md`) and raise the cost for the `*:requestOTP` label. Without this, an attacker can email-bomb arbitrary users.
|
||||
- The OTP code is 8 digits by default, with a 3-minute TTL. Do not extend the TTL - short windows are the whole point.
|
||||
- `authWithOTP` consumes the code; a successful call invalidates the `otpId`. Always show a generic "invalid or expired code" on failure.
|
||||
- If you want OTP **without a password**, set the collection's `Password` option to off and `OTP` on. If both are enabled, users can use either.
|
||||
- OTP emails are sent via the configured SMTP server. In dev, point SMTP at Mailpit or a console logger before testing - do **not** ship with the default "no-reply@example.com" sender.

|

|
||||
## Implement Secure Password Authentication
|
||||
|
||||
Password authentication should include proper error handling, avoid exposing whether emails exist, and correctly manage the auth store.
|
||||
|
||||
**Incorrect (exposing information and poor error handling):**
|
||||
|
||||
```javascript
|
||||
// Dangerous: exposes whether email exists
|
||||
async function login(email, password) {
|
||||
const user = await pb.collection('users').getFirstListItem(`email = "${email}"`);
|
||||
if (!user) {
|
||||
throw new Error('Email not found'); // Reveals email doesn't exist
|
||||
}
|
||||
|
||||
// Manual password check - never do this!
|
||||
if (user.password !== password) {
|
||||
throw new Error('Wrong password'); // Reveals password is wrong
|
||||
}
|
||||
|
||||
return user;
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (secure authentication):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
async function login(email, password) {
|
||||
try {
|
||||
// authWithPassword handles hashing and returns token
|
||||
const authData = await pb.collection('users').authWithPassword(email, password);
|
||||
|
||||
// Token is automatically stored in pb.authStore
|
||||
console.log('Logged in as:', authData.record.email);
|
||||
console.log('Token valid:', pb.authStore.isValid);
|
||||
|
||||
return authData;
|
||||
} catch (error) {
|
||||
// Generic error message - don't reveal if email exists
|
||||
if (error.status === 400) {
|
||||
throw new Error('Invalid email or password');
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Check if user is authenticated
|
||||
function isAuthenticated() {
|
||||
return pb.authStore.isValid;
|
||||
}
|
||||
|
||||
// Get current user
|
||||
function getCurrentUser() {
|
||||
return pb.authStore.record;
|
||||
}
|
||||
|
||||
// Logout
|
||||
function logout() {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
|
||||
// Listen for auth changes
|
||||
pb.authStore.onChange((token, record) => {
|
||||
console.log('Auth state changed:', record?.email || 'logged out');
|
||||
}, true); // true = fire immediately with current state
|
||||
```
|
||||
|
||||
**Auth collection configuration for password auth:**
|
||||
|
||||
```javascript
|
||||
// When creating auth collection via API (superuser only)
|
||||
await pb.collections.create({
|
||||
name: 'users',
|
||||
type: 'auth',
|
||||
fields: [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'avatar', type: 'file', options: { maxSelect: 1 } }
|
||||
],
|
||||
passwordAuth: {
|
||||
enabled: true,
|
||||
identityFields: ['email', 'username'] // Fields that can be used to login
|
||||
},
|
||||
// Require minimum password length
|
||||
// (configured in Admin UI under collection options)
|
||||
});
|
||||
```
|
||||
|
||||
**Security considerations:**
|
||||
- Never store passwords in plain text
|
||||
- Use generic error messages
|
||||
- Implement rate limiting on your server
|
||||
- Consider adding MFA for sensitive applications

|

|

## Manage Auth Tokens Properly
|
||||
|
||||
Auth tokens should be refreshed before expiration, validated on critical operations, and properly cleared on logout. The SDK's authStore handles most of this automatically.
|
||||
|
||||
**Incorrect (ignoring token expiration):**
|
||||
|
||||
```javascript
|
||||
// Bad: never checking token validity
|
||||
async function fetchUserData() {
|
||||
// Token might be expired!
|
||||
const records = await pb.collection('posts').getList();
|
||||
return records;
|
||||
}
|
||||
|
||||
// Bad: manually managing tokens
|
||||
let authToken = localStorage.getItem('token');
|
||||
fetch('/api/posts', {
|
||||
headers: { 'Authorization': authToken } // Token might be invalid
|
||||
});
|
||||
```
|
||||
|
||||
**Correct (proper token management):**
|
||||
|
||||
```javascript
|
||||
import PocketBase from 'pocketbase';
|
||||
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Check token validity before operations
|
||||
async function fetchSecureData() {
|
||||
// authStore.isValid is a client-side check only (JWT expiry parsing).
|
||||
// Always verify server-side with authRefresh() for critical operations.
|
||||
if (!pb.authStore.isValid) {
|
||||
throw new Error('Please log in');
|
||||
}
|
||||
|
||||
return pb.collection('posts').getList();
|
||||
}
|
||||
|
||||
// Refresh token periodically or before expiration
|
||||
async function refreshAuthIfNeeded() {
|
||||
if (!pb.authStore.isValid) {
|
||||
return false;
|
||||
}
|
||||
|

try {
|
||||
// Verifies current token and returns fresh one
|
||||
await pb.collection('users').authRefresh();
|
||||
console.log('Token refreshed');
|
||||
return true;
|
||||
} catch (error) {
|
||||
// Token invalid - user needs to re-authenticate
|
||||
pb.authStore.clear();
|
||||
return false;
|
||||
}
|
||||
}
|
||||
|
||||
// Auto-refresh on app initialization
|
||||
async function initializeAuth() {
|
||||
if (pb.authStore.token) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Listen for auth changes and handle expiration
|
||||
pb.authStore.onChange((token, record) => {
|
||||
if (!token) {
|
||||
// User logged out or token cleared
|
||||
redirectToLogin();
|
||||
}
|
||||
});
|
||||
|
||||
// Setup periodic refresh (e.g., every 10 minutes)
|
||||
setInterval(async () => {
|
||||
if (pb.authStore.isValid) {
|
||||
try {
|

await pb.collection('users').authRefresh();
|
||||
} catch {

pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
}, 10 * 60 * 1000);
|
||||
```
|
||||
|
||||
**SSR / Server-side token handling:**
|
||||
|
||||
```javascript
|
||||
// Server-side: create fresh client per request
|
||||
export async function handleRequest(request) {
|
||||
const pb = new PocketBase('http://127.0.0.1:8090');
|
||||
|
||||
// Load auth from cookie
|
||||
pb.authStore.loadFromCookie(request.headers.get('cookie') || '');
|
||||
|
||||
// Validate and refresh
|
||||
if (pb.authStore.isValid) {
|
||||
try {
|
||||
await pb.collection('users').authRefresh();
|
||||
} catch {
|
||||
pb.authStore.clear();
|
||||
}
|
||||
}
|
||||
|
||||
// ... handle request ...
|
||||
|
||||
// Send updated cookie with secure options
|
||||
const response = new Response();
|
||||
response.headers.set('set-cookie', pb.authStore.exportToCookie({
|
||||
httpOnly: true, // Prevent XSS access to auth token

|

sameSite: 'Lax', // CSRF protection
|

## Use Auth Collections for User Accounts
|
||||
|
||||
Auth collections provide built-in authentication features including secure password hashing, email verification, OAuth2 support, and token management. Using base collections for users requires reimplementing these security-critical features.
|
||||
|
||||
**Incorrect (using base collection for users):**
|
||||
|
||||
```javascript
|
||||
// Base collection loses all auth features
|
||||
const usersCollection = {
|
||||
name: 'users',
|
||||
type: 'base', // Wrong! No auth capabilities
|
||||
schema: [
|
||||
{ name: 'email', type: 'email' },
|
||||
{ name: 'password', type: 'text' }, // Stored in plain text!
|
||||
{ name: 'name', type: 'text' }
|
||||
]
|
||||
};
|
||||
|
||||
// Manual login implementation - insecure
|
||||
const user = await pb.collection('users').getFirstListItem(
|
||||
`email = "${email}" && password = "${password}"` // SQL injection risk!
|
||||
);
|
||||
```
|
||||
|
||||
**Correct (using auth collection):**
|
||||
|
||||
```javascript
|
||||
// Auth collection with built-in security
|
||||
const usersCollection = {
|
||||
name: 'users',
|
||||
type: 'auth', // Enables authentication features
|
||||
schema: [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'avatar', type: 'file', options: { maxSelect: 1 } }
|
||||
],
|
||||
options: {
|
||||
allowEmailAuth: true,
|
||||
allowOAuth2Auth: true,
|
||||
requireEmail: true,
|
||||
minPasswordLength: 8
|
||||
}
|
||||
};
|
||||
|
||||
// Secure authentication with password hashing
|
||||
const authData = await pb.collection('users').authWithPassword(
|
||||
'user@example.com',
|
||||
'securePassword123'
|
||||
);
|
||||
|
||||
// Token automatically stored in authStore
|
||||
// NOTE: Never log tokens in production - shown here for illustration only
|
||||
console.log('Authenticated as:', pb.authStore.record.id);
|
||||
```
|
||||
|
||||
**When to use each type:**
|
||||
- **Auth collection**: User accounts, admin accounts, any entity that needs to log in
|
||||
- **Base collection**: Regular data like posts, products, orders, comments
|
||||
- **View collection**: Read-only aggregations or complex queries

## Choose Appropriate Field Types for Your Data
|
||||
|
||||
Selecting the wrong field type leads to data validation issues, wasted storage, and poor query performance. PocketBase provides specialized field types that enforce constraints at the database level.
|
||||
|
||||
**Incorrect (using text for everything):**
|
||||
|
||||
```javascript
|
||||
// Using plain text fields for structured data
|
||||
const collection = {
|
||||
name: 'products',
|
||||
schema: [
|
||||
{ name: 'price', type: 'text' }, // Should be number
|
||||
{ name: 'email', type: 'text' }, // Should be email
|
||||
{ name: 'website', type: 'text' }, // Should be url
|
||||
{ name: 'active', type: 'text' }, // Should be bool
|
||||
{ name: 'tags', type: 'text' }, // Should be select or json
|
||||
{ name: 'created', type: 'text' } // Should be autodate
|
||||
]
|
||||
};
|
||||
// No validation, inconsistent data, manual parsing required
|
||||
```
|
||||
|
||||
**Correct (using appropriate field types):**
|
||||
|
||||
```javascript
|
||||
// Using specialized field types with proper validation
|
||||
const collection = {
|
||||
name: 'products',
|
||||
type: 'base',
|
||||
schema: [
|
||||
{ name: 'price', type: 'number', options: { min: 0 } },
|
||||
{ name: 'email', type: 'email' },
|
||||
{ name: 'website', type: 'url' },
|
||||
{ name: 'active', type: 'bool' },
|
||||
{ name: 'tags', type: 'select', options: {
|
||||
maxSelect: 5,
|
||||
values: ['electronics', 'clothing', 'food', 'other']
|
||||
}},
|
||||
{ name: 'metadata', type: 'json' }
|
||||
// created/updated are automatic system fields
|
||||
]
|
||||
};
|
||||
// Built-in validation, proper indexing, type-safe queries
|
||||
```
|
||||
|
||||
**Available field types:**
|
||||
- `text` - Plain text with optional min/max length, regex pattern
|
||||
- `number` - Integer or decimal with optional min/max
|
||||
- `bool` - True/false values
|
||||
- `email` - Email with format validation
|
||||
- `url` - URL with format validation
|
||||
- `date` - Date/datetime values
|
||||
- `autodate` - Auto-set on create/update
|
||||
- `select` - Single or multi-select from predefined values
|
||||
- `json` - Arbitrary JSON data
|
||||
- `file` - File attachments
|
||||
- `relation` - References to other collections
|
||||
- `editor` - Rich text HTML content

## Use GeoPoint Fields for Location Data
|
||||
|
||||
PocketBase provides a dedicated GeoPoint field type for storing geographic coordinates with built-in distance query support via `geoDistance()`.
|
||||
|
||||
**Incorrect (storing coordinates as separate fields):**
|
||||
|
||||
```javascript
|
||||
// Separate lat/lon fields - no built-in distance queries
|
||||
const placesSchema = [
|
||||
{ name: 'name', type: 'text' },
|
||||
{ name: 'latitude', type: 'number' },
|
||||
{ name: 'longitude', type: 'number' }
|

];
|
||||
|
||||
// Manual distance calculation - complex and slow
|
||||
async function findNearby(lat, lon, maxKm) {
|
||||
const places = await pb.collection('places').getFullList();
|
||||
|
||||
// Calculate distance for every record client-side
|
||||
return places.filter(place => {
|
||||
const dist = haversine(lat, lon, place.latitude, place.longitude);
|
||||
return dist <= maxKm;
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (using GeoPoint field):**
|
||||
|
||||
```javascript
|
||||
// GeoPoint field stores coordinates as { lon, lat } object
|
||||
const placesSchema = [
|

|

await pb.collection('places').create({

|
||||
const nearbyPlaces = await findNearby(-73.9857, 40.7580, 5);
|
||||
|
||||
// Use in API rules for location-based access
|
||||
// listRule: geoDistance(location, @request.query.point) <= 10
|
||||
```
|
||||
|
||||
**geoDistance() function:**
|
||||
|
||||
```javascript
|
||||
// Syntax: geoDistance(geopointField, referencePoint)
|
||||
// Returns: distance in kilometers
|
||||
|
||||
// In filter expressions
|
||||
filter: 'geoDistance(location, "-73.9857,40.7484") <= 5'
|

// With parameter binding (recommended)
|
||||
filter: pb.filter('geoDistance(location, {:center}) <= {:radius}', {
|

center: { lon: -73.9857, lat: 40.7484 },
|

radius: 5
|
||||
})
|
||||
|
||||
// Sorting by distance
|
||||
sort: 'geoDistance(location, "-73.9857,40.7484")' // Closest first
|
||||
sort: '-geoDistance(location, "-73.9857,40.7484")' // Farthest first
|
||||
```
|
||||
|
||||
**GeoPoint data format:**
|
||||
|
||||
```javascript
|
||||
// Object format (recommended)
|
||||
{ lon: -73.9857, lat: 40.7484 }
|
||||
|
||||
// String format
|
||||
"-73.9857,40.7484" // "lon,lat" order
|
||||
|
||||
// Important: longitude comes FIRST (GeoJSON convention)
|
||||
```
|
||||
|
||||
**Use cases:**
|
||||
- Store-locator / find nearby
|
||||
- Delivery radius validation
|
||||
- Geofencing in API rules
|
||||
- Location-based search results
|
||||
|
||||
**Limitations:**
|
||||
- Spherical Earth calculation (accurate to ~0.3%)
|
||||
- No polygon/area containment queries
|
||||
- Single point per field (use multiple fields for routes)

## Create Indexes for Frequently Filtered Fields
|
||||
|
||||
PocketBase uses SQLite which benefits significantly from proper indexing. Queries filtering or sorting on unindexed fields perform full table scans.
|
||||
|
||||
**Incorrect (no indexes on filtered fields):**
|
||||
|
||||
```javascript
|
||||
// Querying without indexes
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'author = "user123" && status = "published"',
|
||||
sort: '-publishedAt'
|
||||
});
|
||||
// Full table scan on large collections - very slow
|
||||
|
||||
// API rules also query without indexes
|
||||
// listRule: "author = @request.auth.id"
|
||||
// Every list request scans entire table
|
||||
```
|
||||
|
||||
**Correct (indexed fields):**
|
||||
|
||||
```javascript
|
||||
// Create collection with indexes via Admin UI or migration
|
||||
// In PocketBase Admin: Collection > Indexes > Add Index
|
||||
|
||||
// Common index patterns:
|
||||
// 1. Single field index for equality filters
|
||||
// CREATE INDEX idx_posts_author ON posts(author)
|
||||
|
||||
// 2. Composite index for multiple filters
|
||||
// CREATE INDEX idx_posts_author_status ON posts(author, status)
|
||||
|
||||
// 3. Index with sort field
|
||||
// CREATE INDEX idx_posts_status_published ON posts(status, publishedAt DESC)
|
||||
|
||||
// Queries now use indexes
|
||||
const posts = await pb.collection('posts').getList(1, 20, {
|
||||
filter: 'author = "user123" && status = "published"',
|
||||
sort: '-publishedAt'
|
||||
});
|
||||
// Index scan - fast even with millions of records
|
||||
|
||||
// For unique constraints (e.g., slug)
|
||||
// CREATE UNIQUE INDEX idx_posts_slug ON posts(slug)
|
||||
```
|
||||
|
||||
**Index recommendations:**
|
||||
- Fields used in `filter` expressions
|
||||
- Fields used in `sort` parameters
|
||||
- Fields used in API rules (`listRule`, `viewRule`, etc.)
|
||||
- Relation fields (automatically indexed)
|
||||
- Unique fields like slugs or codes
|
||||
|
||||
**Index considerations for SQLite:**
|
||||
- Composite indexes work left-to-right (order matters)
|
||||
- Too many indexes slow down writes
|
||||
- Use `EXPLAIN QUERY PLAN` in SQL to verify index usage
|
||||
- Partial indexes for filtered subsets
|
||||
|
||||
```sql
|
||||
-- Check if index is used
|
||||
EXPLAIN QUERY PLAN
|
||||
SELECT * FROM posts WHERE author = 'user123' AND status = 'published';
|
||||
-- Should show "USING INDEX" not "SCAN"
|
||||

## Configure Relations with Proper Cascade Options
|
||||
|
||||
Relation fields connect collections together. Proper cascade configuration ensures data integrity when referenced records are deleted.
|
||||
|
||||
**Incorrect (default cascade behavior not considered):**
|
||||
|
||||
```javascript
|
||||
// Relation without considering deletion behavior
|
||||
const ordersSchema = [
|
||||
{ name: 'customer', type: 'relation', options: {
|
||||
collectionId: 'customers_collection_id',
|
||||
maxSelect: 1
|
||||
// No cascade options specified - defaults may cause issues
|
||||
}},
|
||||
{ name: 'products', type: 'relation', options: {
|
||||
collectionId: 'products_collection_id'
|
||||
// Multiple products, no cascade handling
|
||||
}}
|
||||
];
|
||||
|
||||
// Deleting a customer may fail or orphan orders
|
||||
await pb.collection('customers').delete(customerId);
|
||||
// Error: record is referenced by other records
|
||||
```
|
||||
|
||||
**Correct (explicit cascade configuration):**
|
||||
|
||||
```javascript
|
||||
// Carefully configured relations
|
||||
const ordersSchema = [
|
||||
{
|
||||

|
||||
type: 'relation',
|
||||
options: {
|
||||
collectionId: 'products_collection_id',
|
||||
maxSelect: 99,
|
||||
cascadeDelete: false
|
||||
}
|
||||
}
|
||||
];
|
||||
|
||||
// For dependent data like comments - cascade delete makes sense
|
||||
const commentsSchema = [
|
||||
{
|
||||
name: 'post',
|
||||
type: 'relation',
|
||||
options: {
|
||||
collectionId: 'posts_collection_id',
|
||||
maxSelect: 1,
|
||||
cascadeDelete: true // Delete comments when post is deleted
|
||||
}
|
||||
}
|
||||
];
|
||||
// NOTE: For audit logs, avoid cascadeDelete - logs should be retained
|
||||
// for compliance/forensics even after the referenced user is deleted.
|
||||
// Use cascadeDelete: false and handle user deletion separately.
|
||||
|
||||
// Handle deletion manually when cascade is false
|
||||
try {
|
||||
await pb.collection('customers').delete(customerId);
|
||||
} catch (e) {
|
||||
if (e.status === 400) {
|
||||
// Customer has orders - handle appropriately
|
||||
// Option 1: Soft delete (set 'deleted' flag)
|
||||
// Option 2: Reassign orders
|
||||
// Option 3: Delete orders first
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Cascade options:**
|
||||
- `cascadeDelete: true` - Delete referencing records when referenced record is deleted
|
||||
- `cascadeDelete: false` - Block deletion if references exist (default for required relations)
|
||||
|
||||
**Best practices:**
|
||||
- Use `cascadeDelete: true` for dependent data (comments on posts, logs for users)
|
||||
- Use `cascadeDelete: false` for important data (orders, transactions)
|
||||
- Consider soft deletes for audit trails
|
||||
- Document your cascade strategy

|

## Use View Collections for Complex Read-Only Queries
|
||||
|
||||
View collections execute custom SQL queries and expose results through the standard API. They're ideal for aggregations, joins, and computed fields without duplicating logic across your application.
|
||||
|
||||
**Incorrect (computing aggregations client-side):**
|
||||
|
||||
```javascript
|
||||
// Fetching all records to compute stats client-side
|
||||
const orders = await pb.collection('orders').getFullList();
|
||||
const products = await pb.collection('products').getFullList();
|
||||
|
||||
// Expensive client-side computation
|
||||
const stats = orders.reduce((acc, order) => {
|
||||
const product = products.find(p => p.id === order.product);
|
||||
acc.totalRevenue += order.quantity * product.price;
|
||||
acc.orderCount++;
|
||||
return acc;
|
||||
}, { totalRevenue: 0, orderCount: 0 });
|
||||
// Fetches all data, slow, memory-intensive
|
||||
```
|
||||
|
||||
**Correct (using view collection):**
|
||||
|
||||
```javascript
|
||||
// Create a view collection in PocketBase Admin UI or via API
|
||||
// View SQL:
|
||||
// SELECT
|
||||
// p.id,
|
||||
// p.name,
|
||||
// COUNT(o.id) as order_count,
|
||||
// SUM(o.quantity) as total_sold,
|
||||
// SUM(o.quantity * p.price) as revenue
|
||||
// FROM products p
|
||||
// LEFT JOIN orders o ON o.product = p.id
|
||||
// GROUP BY p.id
|
||||
|
||||
// Simple, efficient query
|
||||
const productStats = await pb.collection('product_stats').getList(1, 20, {
|
||||
sort: '-revenue'
|
||||
});
|
||||
|
||||
// Each record has computed fields
|
||||
productStats.items.forEach(stat => {
|
||||
console.log(`${stat.name}: ${stat.order_count} orders, $${stat.revenue}`);
|
||||
});
|
||||
```
|
||||
|
||||
**View collection use cases:**
|
||||
- Aggregations (COUNT, SUM, AVG)
|
||||
- Joining data from multiple collections
|
||||
- Computed/derived fields
|
||||
- Denormalized read models
|
||||
- Dashboard statistics
|
||||
|
||||
**Limitations:**
|
||||
- Read-only (no create/update/delete)
|
||||
- Must return `id` column
|
||||
- No realtime subscriptions
|
||||
- API rules still apply for access control

## Implement Proper Backup Strategies
|
||||
|
||||
Regular backups are essential for production deployments. PocketBase provides built-in backup functionality and supports external S3 storage.
|
||||
|
||||
**Incorrect (no backup strategy):**
|
||||
|
||||
```javascript
|
||||
// No backups at all - disaster waiting to happen
|
||||
// Just running: ./pocketbase serve
|
||||
|
||||
// Manual file copy while server running - can corrupt data
|
||||
// cp pb_data/data.db backup/
|
||||
|
||||
// Only backing up database, missing files
|
||||
// sqlite3 pb_data/data.db ".backup backup.db"
|
||||
```
|
||||
|
||||
**Correct (comprehensive backup strategy):**
|
||||
|
||||
```javascript
|
||||
// 1. Using PocketBase Admin API for backups
|
||||
const adminPb = new PocketBase('http://127.0.0.1:8090');
|
||||
await adminPb.collection('_superusers').authWithPassword(admin, password);
|
||||
|
||||
// Create backup (includes database and files)
|
||||
async function createBackup(name = '') {
|
||||
const backup = await adminPb.backups.create(name);
|
||||
console.log('Backup created:', backup.key);
|
||||
return backup;
|
||||
}
|
||||
|
||||
// List available backups
|
||||
async function listBackups() {
|
||||
const backups = await adminPb.backups.getFullList();
|
||||
backups.forEach(b => {
|
||||
console.log(`${b.key} - ${b.size} bytes - ${b.modified}`);
|
||||
});
|
||||
return backups;
|
||||
}
|
||||
|
||||
// Download backup
|
||||
async function downloadBackup(key) {
|
||||
const token = await adminPb.files.getToken();
|
||||
const url = adminPb.backups.getDownloadURL(token, key);
|
||||
// url can be used to download the backup file
|
||||
return url;
|
||||
}
|
||||
|
||||
// Restore from backup (CAUTION: overwrites current data!)
|
||||
async function restoreBackup(key) {
|
||||
await adminPb.backups.restore(key);
|
||||
console.log('Restore initiated - server will restart');
|
||||
}
|
||||
|
||||
// Delete old backups
|
||||
async function cleanupOldBackups(keepCount = 7) {
|
||||
const backups = await adminPb.backups.getFullList();
|
||||
|
||||
// Sort by date, keep newest
|
||||
const sorted = backups.sort((a, b) =>
|
||||
new Date(b.modified) - new Date(a.modified)
|
||||
);
|
||||
|
||||
const toDelete = sorted.slice(keepCount);
|
||||
for (const backup of toDelete) {
|
||||
await adminPb.backups.delete(backup.key);
|
||||
console.log('Deleted old backup:', backup.key);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Automated backup script (cron job):**
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# backup.sh - Run daily via cron
|
||||
|
||||
POCKETBASE_URL="http://127.0.0.1:8090"
|
||||
ADMIN_EMAIL="admin@example.com"
|
||||
ADMIN_PASSWORD="your-secure-password"
|
||||
BACKUP_DIR="/path/to/backups"
|
||||
KEEP_DAYS=7
|
||||
|
||||
# Create timestamp
|
||||
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
|
||||
|
||||
# Create backup via API
|
||||
curl -X POST "${POCKETBASE_URL}/api/backups" \
|
||||
-H "Authorization: $(curl -s -X POST "${POCKETBASE_URL}/api/collections/_superusers/auth-with-password" \
|
||||
-d "identity=${ADMIN_EMAIL}&password=${ADMIN_PASSWORD}" | jq -r '.token')" \
|
||||
-d "name=backup_${TIMESTAMP}"
|
||||
|
||||
# Clean old local backups
|
||||
find "${BACKUP_DIR}" -name "*.zip" -mtime +${KEEP_DAYS} -delete
|
||||
|
||||
echo "Backup completed: backup_${TIMESTAMP}"
|
||||
```
|
||||
|
||||
**Configure S3 for backup storage:**
|
||||
|
||||
```javascript
|
||||
// In Admin UI: Settings > Backups > S3
|
||||
// Or via API:
|
||||
await adminPb.settings.update({
|
||||
backups: {
|
||||
s3: {
|
||||
enabled: true,
|
||||
bucket: 'my-pocketbase-backups',
|
||||
region: 'us-east-1',
|
||||
endpoint: 's3.amazonaws.com',
|
||||
accessKey: process.env.AWS_ACCESS_KEY,
|
||||
secret: process.env.AWS_SECRET_KEY
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**Backup best practices:**
|
||||
|
||||
| Aspect | Recommendation |
|
||||
|--------|---------------|
|
||||
| Frequency | Daily minimum, hourly for critical apps |
|
||||
| Retention | 7-30 days of daily backups |
|
||||
| Storage | Off-site (S3, separate server) |
|
||||
| Testing | Monthly restore tests |
|
||||
| Monitoring | Alert on backup failures |
|
||||
|
||||
**Pre-backup checklist:**
|
||||
- [ ] S3 or external storage configured
|
||||
- [ ] Automated schedule set up
|
||||
- [ ] Retention policy defined
|
||||
- [ ] Restore procedure documented
|
||||
- [ ] Restore tested successfully

|

## Configure Production Settings Properly
|
||||
|
||||
Production deployments require proper configuration of URLs, secrets, SMTP, and security settings.
|
||||
|
||||
**Incorrect (development defaults in production):**
|
||||
|
||||
```bash
|
||||
# Running with defaults - insecure!
|
||||
./pocketbase serve
|
||||
|
||||
# Hardcoded secrets
|
||||
./pocketbase serve --encryptionEnv="mySecretKey123"
|
||||
|
||||
# Wrong origin for CORS
|
||||
# Leaving http://localhost:8090 as allowed origin
|
||||
```
|
||||
|
||||
**Correct (production configuration):**
|
||||
|
||||
```bash
|
||||
# Production startup with essential flags
|
||||
./pocketbase serve \
|
||||
--http="0.0.0.0:8090" \
|
||||
--origins="https://myapp.com,https://www.myapp.com" \
|
||||
--encryptionEnv="PB_ENCRYPTION_KEY"
|
||||
|
||||
# Using environment variables
|
||||
export PB_ENCRYPTION_KEY="your-32-char-encryption-key-here"
|
||||
export SMTP_HOST="smtp.sendgrid.net"
|
||||
export SMTP_PORT="587"
|
||||
export SMTP_USER="apikey"
|
||||
export SMTP_PASS="your-sendgrid-api-key"
|
||||
|
||||
./pocketbase serve --http="0.0.0.0:8090"
|
||||
```
|
||||
|
||||
**Configure SMTP for emails:**
|
||||
|
||||
```javascript
|
||||
// Via Admin UI or API
|
||||
await adminPb.settings.update({
|
||||
smtp: {
|
||||
enabled: true,
|
||||
host: process.env.SMTP_HOST,
|
||||
port: parseInt(process.env.SMTP_PORT),
|
||||
username: process.env.SMTP_USER,
|
||||
password: process.env.SMTP_PASS,
|
||||
tls: true
|
||||
},
|
||||
meta: {
|
||||
appName: 'My App',
|
||||
appURL: 'https://myapp.com',
|
||||
senderName: 'My App',
|
||||
senderAddress: 'noreply@myapp.com'
|
||||
}
|
||||
});
|
||||
|
||||
// Test email configuration
|
||||
await adminPb.settings.testEmail('users', 'test@example.com', 'verification');
|
||||
```
|
||||
|
||||
**Configure S3 for file storage:**
|
||||
|
||||
```javascript
|
||||
// Move file storage to S3 for scalability
|
||||
await adminPb.settings.update({
|
||||
s3: {
|
||||
enabled: true,
|
||||
bucket: 'my-app-files',
|
||||
region: 'us-east-1',
|
||||
endpoint: 's3.amazonaws.com',
|
||||
accessKey: process.env.AWS_ACCESS_KEY,
|
||||
secret: process.env.AWS_SECRET_KEY,
|
||||
forcePathStyle: false
|
||||
}
|
||||
});
|
||||
|
||||
// Test S3 connection
|
||||
await adminPb.settings.testS3('storage');
|
||||
```
|
||||
|
||||

# Ensure .env is in .gitignore
|
||||
echo ".env" >> .gitignore
|
||||
```
|
||||
|
||||
**Production checklist:**
|
||||
|
||||
- [ ] HTTPS enabled (via reverse proxy)
|
||||
- [ ] Strong encryption key set
|
||||
- [ ] CORS origins configured
|
||||

title: Enable Rate Limiting for API Protection
|

impact: MEDIUM
|

impactDescription: Prevents abuse, brute-force attacks, and DoS
|
||||
tags: production, security, rate-limiting, abuse-prevention

|
||||
|
||||
## Enable Rate Limiting for API Protection
|
||||
|
||||
PocketBase v0.23+ includes built-in rate limiting. Enable it to protect against brute-force attacks, API abuse, and excessive resource consumption.
|
||||
|
||||
> **v0.36.7 behavioral change:** the built-in limiter switched from a sliding-window to a **fixed-window** strategy. This is cheaper and more predictable, but it means a client can send `2 * maxRequests` in quick succession if they straddle the window boundary. Size your limits with that worst case in mind, and put Nginx/Caddy rate limiting in front of PocketBase for defense in depth (see examples below).
|
||||
|
||||
**Incorrect (no rate limiting):**
|
||||
|
||||
```bash
|
||||
# Running without rate limiting
|
||||
./pocketbase serve
|
||||
|
||||
# Vulnerable to:
|
||||
# - Brute-force password attacks
|
||||
# - API abuse and scraping
|
||||
# - DoS from excessive requests
|
||||
# - Account enumeration attempts
|
||||
```
|
||||
|
||||
**Correct (enable rate limiting):**
|
||||
|
||||
```bash
|
||||
# Enable via command line flag
|
||||
./pocketbase serve --rateLimiter=true
|
||||
|
||||
# Or configure specific limits (requests per second per IP)
|
||||
./pocketbase serve --rateLimiter=true --rateLimiterRPS=10
|
||||
```
|
||||
|
||||
**Configure via Admin Dashboard:**
|
||||
|
||||
Navigate to Settings > Rate Limiter:
|
||||
- **Enable rate limiter**: Toggle on
|
||||
- **Max requests/second**: Default 10, adjust based on needs
|
||||
- **Exempt endpoints**: Optionally whitelist certain paths
|
||||
|
||||
**Configure programmatically (Go/JS hooks):**
|
||||
|
||||
```javascript
|
||||
// In pb_hooks/rate_limit.pb.js
|
||||
routerAdd("GET", "/api/public/*", (e) => {
|
||||
// Custom rate limit for specific endpoints
|
||||
}, $apis.rateLimit(100, "10s")); // 100 requests per 10 seconds
|
||||
|
||||
// Stricter limit for auth endpoints
|
||||
routerAdd("POST", "/api/collections/users/auth-*", (e) => {
|
||||
// Auth endpoints need stricter limits
|
||||
}, $apis.rateLimit(5, "1m")); // 5 attempts per minute
|
||||
```
|
||||
|
||||
**Rate limiting with reverse proxy (additional layer):**
|
||||
|
||||
```nginx
|
||||
# Nginx rate limiting (defense in depth)
|
||||
http {
|
||||
# Define rate limit zones
|
||||
limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;
|
||||
limit_req_zone $binary_remote_addr zone=auth:10m rate=1r/s;
|
||||
|
||||
server {
|
||||
# General API rate limit
|
||||
location /api/ {
|
||||
limit_req zone=api burst=20 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
|
||||
# Strict limit for auth endpoints
|
||||
location /api/collections/users/auth {
|
||||
limit_req zone=auth burst=5 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
|
||||
# Stricter limit for superuser auth
|
||||
location /api/collections/_superusers/auth {
|
||||
limit_req zone=auth burst=3 nodelay;
|
||||
proxy_pass http://pocketbase;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```caddyfile
|
||||
# Caddy with rate limiting plugin
|
||||
myapp.com {
|
||||
rate_limit {
|
||||
zone api {
|
||||

|
||||

|
||||
window 10s
|
||||
}
|
||||
zone auth {
|
||||
key {remote_host}
|
||||
events 5
|
||||
window 1m
|
||||
}
|
||||
}
|
||||
|
||||
@auth path /api/collections/*/auth*
|
||||
handle @auth {
|
||||
rate_limit { zone auth }
|
||||
reverse_proxy 127.0.0.1:8090
|
||||
}
|
||||
|
||||
handle {
|
||||
rate_limit { zone api }
|
||||
reverse_proxy 127.0.0.1:8090
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Handle rate limit errors in client:**
|
||||
|
||||
```javascript
|
||||
async function makeRequest(fn, retries = 0, maxRetries = 3) {
|
||||
try {
|
||||
return await fn();
|
||||
} catch (error) {
|
||||
if (error.status === 429 && retries < maxRetries) {
|
||||
// Rate limited - wait and retry with limit
|
||||
const retryAfter = error.response?.retryAfter || 60;
|
||||
console.log(`Rate limited. Retry ${retries + 1}/${maxRetries} after ${retryAfter}s`);
|
||||
|
||||
// Show user-friendly message
|
||||
showMessage('Too many requests. Please wait a moment.');
|
||||
|
||||
await sleep(retryAfter * 1000);
|
||||
return makeRequest(fn, retries + 1, maxRetries);
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
const result = await makeRequest(() =>
|
||||
pb.collection('posts').getList(1, 20)
|
||||
);
|
||||
```
|
||||
|
||||
**Recommended limits by endpoint type:**
|
||||
|
||||
| Endpoint Type | Suggested Limit | Reason |
|
||||
|--------------|-----------------|--------|
|
||||
| Auth endpoints | 5-10/min | Prevent brute-force |
|
||||
| Password reset | 3/hour | Prevent enumeration |
|
||||
| Record creation | 30/min | Prevent spam |
|
||||
| General API | 60-100/min | Normal usage |
|
||||
| Public read | 100-200/min | Higher for reads |
|
||||
| File uploads | 10/min | Resource-intensive |
|
||||
|
||||
**Monitoring rate limit hits:**
|
||||
|
||||
```javascript
|
||||
// Check PocketBase logs for rate limit events
|
||||
// Or set up alerting in your monitoring system
|
||||
|
||||
// Client-side tracking
|
||||
pb.afterSend = function(response, data) {
|
||||
if (response.status === 429) {
|
||||
trackEvent('rate_limit_hit', {
|
||||
endpoint: response.url,
|
||||
timestamp: new Date()
|
||||
});
|
||||
}
|
||||
return data;
|
||||
};

|

|

## Configure Reverse Proxy Correctly
|
||||
|
||||
Use a reverse proxy (Nginx, Caddy) for HTTPS termination, caching, rate limiting, and security headers.
|
||||
|
||||
**Incorrect (exposing PocketBase directly):**
|
||||
|
||||
```bash
|
||||
# Direct exposure - no HTTPS, no rate limiting
|
||||
./pocketbase serve --http="0.0.0.0:8090"
|
||||
|
||||
# Port forwarding without proxy
|
||||
iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8090
|
||||
# Still no HTTPS!
|
||||
```
|
||||
|
||||
**Correct (Caddy - simplest option):**
|
||||
|
||||
```caddyfile
|
||||
# /etc/caddy/Caddyfile
|
||||
myapp.com {
|
||||
# Automatic HTTPS via Let's Encrypt
|
||||
reverse_proxy 127.0.0.1:8090 {
|
||||
# Required for SSE/Realtime
|
||||
flush_interval -1
|
||||
}
|
||||
|
||||
# Security headers
|
||||
header {
|
||||
X-Content-Type-Options "nosniff"
|
||||
X-Frame-Options "DENY"
|
||||
Strict-Transport-Security "max-age=63072000; includeSubDomains; preload"
|
||||
Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'"

|
||||
|
||||
## Tune OS and Runtime for PocketBase Scale
|
||||
|
||||
Three low-effort OS/runtime knobs have outsized impact on production stability: open-file limits for realtime connections, Go memory limits for constrained hosts, and settings encryption for shared or externally-backed infrastructure. None of these are set automatically.
|
||||
|
||||
**Incorrect (default OS limits, no memory governor, plain-text settings):**
|
||||
|
||||
```bash
|
||||
# Start without raising the file descriptor limit
|
||||
/root/pb/pocketbase serve yourdomain.com
|
||||
# → "Too many open files" once concurrent realtime connections exceed ~1024
|
||||
|
||||
# Start in a container that has a 512 MB RAM cap without GOMEMLIMIT
|
||||
docker run -m 512m pocketbase serve ...
|
||||
# → OOM kill during large file upload because Go GC doesn't respect cgroup limits
|
||||
|
||||
# Store SMTP password and S3 secret as plain JSON in pb_data/data.db
|
||||
pocketbase serve # no --encryptionEnv
|
||||
# → Anyone who obtains the database backup can read all credentials
|
||||
```
|
||||
|
||||
**Correct:**
|
||||
|
||||
```bash
|
||||
# 1. Raise the open-file limit before starting (Linux/macOS)
|
||||
# Check current limit first:
|
||||
ulimit -a | grep "open files"
|
||||
# Temporarily raise to 4096 for the current session:
|
||||
ulimit -n 4096
|
||||
/root/pb/pocketbase serve yourdomain.com
|
||||
|
||||
# Or persist it via systemd (recommended for production):
|
||||
# /lib/systemd/system/pocketbase.service
|
||||
# [Service]
|
||||
# LimitNOFILE = 4096
|
||||
# ...
|
||||
|
||||
# 2. Cap Go's soft memory target on memory-constrained hosts
|
||||
# (instructs the GC to be more aggressive before the kernel OOM-kills the process)
|
||||
GOMEMLIMIT=512MiB /root/pb/pocketbase serve yourdomain.com
|
||||
|
||||
# 3. Encrypt application settings at rest
|
||||
# Generate a random 32-character key once:
|
||||
export PB_ENCRYPTION_KEY="z76NX9WWiB05UmQGxw367B6zM39T11fF"
|
||||
# Start with the env-var name (not the value) as the flag argument:
|
||||
pocketbase serve --encryptionEnv=PB_ENCRYPTION_KEY
|
||||
```
|
||||
|
||||
**Docker deployment pattern (v0.36.8):**
|
||||
|
||||
```dockerfile
|
||||
FROM alpine:latest
|
||||
ARG PB_VERSION=0.36.8
|
||||
|
||||
RUN apk add --no-cache unzip ca-certificates
|
||||
|
||||
ADD https://github.com/pocketbase/pocketbase/releases/download/v${PB_VERSION}/pocketbase_${PB_VERSION}_linux_amd64.zip /tmp/pb.zip
|
||||
RUN unzip /tmp/pb.zip -d /pb/
|
||||
|
||||
# Uncomment to bundle pre-written migrations or hooks:
|
||||
# COPY ./pb_migrations /pb/pb_migrations
|
||||
# COPY ./pb_hooks /pb/pb_hooks
|
||||
|
||||
EXPOSE 8080
|
||||
|
||||
# Mount a volume at /pb/pb_data to persist data across container restarts
|
||||
CMD ["/pb/pocketbase", "serve", "--http=0.0.0.0:8080"]
|
||||
```
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
services:
|
||||

|
||||
volumes:
|
||||
pb_data:
|
||||
```
|
||||
|
||||
**Quick-reference checklist:**
|
||||
|
||||
| Concern | Fix |
|
||||
|---------|-----|
|
||||
| `Too many open files` errors | `ulimit -n 4096` (or `LimitNOFILE=4096` in systemd) |
|
||||
| OOM kill on constrained host | `GOMEMLIMIT=512MiB` env var |
|

title: Optimize SQLite for Production
|
||||
impact: LOW-MEDIUM
|
||||
impactDescription: Better performance and reliability for SQLite database
|
||||
tags: production, sqlite, database, performance

|
||||
## Optimize SQLite for Production
|
||||
|
||||
PocketBase uses SQLite with optimized defaults. Understanding its characteristics helps optimize performance and avoid common pitfalls. PocketBase uses two separate databases: `data.db` (application data) and `auxiliary.db` (logs and ephemeral data), which reduces write contention.
|
||||
|
||||
**Incorrect (ignoring SQLite characteristics):**
|
||||
|
||||
```javascript
|
||||
// Heavy concurrent writes - SQLite bottleneck
|
||||
async function bulkInsert(items) {
|
||||
// Parallel writes cause lock contention
|
||||
await Promise.all(items.map(item =>
|
||||
pb.collection('items').create(item)
|
||||
));
|
||||
}
|
||||
|
||||
// Not using transactions for batch operations
|
||||
async function updateMany(items) {
|
||||
for (const item of items) {
|
||||
await pb.collection('items').update(item.id, item);
|
||||
}
|
||||
// Each write is a separate transaction - slow!
|
||||
}
|
||||
|
||||
// Large text fields without consideration
|
||||
const schema = [{
|
||||
name: 'content',
|
||||
type: 'text' // Could be megabytes - affects all queries
|
||||
}];
|
||||
```
|
||||
|
||||
**Correct (SQLite-optimized patterns):**
|
||||
|
||||
```javascript
|
||||
// Use batch operations for multiple writes
|
||||
async function bulkInsert(items) {
|
||||
const batch = pb.createBatch();
|
||||
items.forEach(item => {
|
||||
batch.collection('items').create(item);
|
||||
});
|
||||
await batch.send(); // Single transaction, much faster
|
||||
}
|
||||
|
||||
// Batch updates
|
||||
async function updateMany(items) {
|
||||
const batch = pb.createBatch();
|
||||
items.forEach(item => {
|
||||
batch.collection('items').update(item.id, item);
|
||||
});
|
||||
await batch.send();
|
||||
}
|
||||
|
||||
// For very large batches, chunk them
|
||||
async function bulkInsertLarge(items, chunkSize = 100) {
|
||||
for (let i = 0; i < items.length; i += chunkSize) {
|
||||
const chunk = items.slice(i, i + chunkSize);
|
||||
const batch = pb.createBatch();
|
||||
chunk.forEach(item => batch.collection('items').create(item));
|
||||
await batch.send();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Schema considerations:**
|
||||
|
||||
```javascript
|
||||
// Separate large content into dedicated collection
|
||||
const postsSchema = [
|
||||
{ name: 'title', type: 'text' },
|
||||
{ name: 'summary', type: 'text', options: { maxLength: 500 } },
|
||||
{ name: 'author', type: 'relation' }
|
||||
// Content in separate collection
|
||||
];
|
||||
|
||||
const postContentsSchema = [
|
||||
{ name: 'post', type: 'relation', required: true },
|
||||
{ name: 'content', type: 'editor' } // Large HTML content
|
||||
];
|
||||
|
||||
// Fetch content only when needed
|
||||
async function getPostList() {
|
||||
return pb.collection('posts').getList(1, 20); // Fast, no content
|
||||
}
|
||||
|
||||
async function getPostWithContent(id) {
|
||||
const post = await pb.collection('posts').getOne(id);
|
||||
const content = await pb.collection('post_contents').getFirstListItem(
|
||||
pb.filter('post = {:id}', { id })
|
||||
);
|
||||
return { ...post, content: content.content };
|
||||
}
|
||||
```
|
||||
|
||||
**PocketBase default PRAGMA settings:**
|
||||
|
||||
PocketBase already configures optimal SQLite settings. You do not need to set these manually unless using a custom SQLite driver:
|
||||
|
||||
```sql
|
||||
PRAGMA busy_timeout = 10000; -- Wait 10s for locks instead of failing immediately
|
||||
PRAGMA journal_mode = WAL; -- Write-Ahead Logging: concurrent reads during writes
|
||||
PRAGMA journal_size_limit = 200000000; -- Limit WAL file to ~200MB
|
||||
PRAGMA synchronous = NORMAL; -- Balanced durability/performance (safe with WAL)
|
||||
PRAGMA foreign_keys = ON; -- Enforce relation integrity
|
||||
PRAGMA temp_store = MEMORY; -- Temp tables in memory (faster sorts/joins)
|
||||
PRAGMA cache_size = -32000; -- 32MB page cache
|
||||
```
|
||||
|
||||
WAL mode is the most impactful setting -- it allows multiple concurrent readers while a single writer is active, which is critical for PocketBase's concurrent API request handling.
|
||||
|
||||
**Index optimization:**
|
||||
|
||||
```sql
|
||||
-- Create indexes for commonly filtered/sorted fields
|
||||
CREATE INDEX idx_posts_author ON posts(author);
|
||||
CREATE INDEX idx_posts_created ON posts(created DESC);
|
||||
CREATE INDEX idx_posts_status_created ON posts(status, created DESC);
|
||||
|
||||
-- Verify indexes are being used
|
||||
EXPLAIN QUERY PLAN
|
||||
SELECT * FROM posts WHERE author = 'xxx' ORDER BY created DESC;
|
||||
-- Should show: "USING INDEX idx_posts_author"
|
||||
```
|
||||
|
||||
**SQLite limitations and workarounds:**
|
||||
|
||||
| Limitation | Workaround |
|
||||
|------------|------------|
|
||||
| Single writer | Use batch operations, queue writes |
|
||||
| No full-text by default | Use view collections with FTS5 |
|
||||
| File-based | SSD storage, avoid network mounts |
|
||||
| Memory for large queries | Pagination, limit result sizes |
|
||||
|
||||
**Performance monitoring:**
|
||||
|
||||
```javascript
|
||||
// Monitor slow queries via hooks (requires custom PocketBase build)
|
||||
// Or use SQLite's built-in profiling
|
||||
|
||||
// From sqlite3 CLI:
|
||||
// .timer on
|
||||
// SELECT * FROM posts WHERE author = 'xxx';
|
||||
// Run Time: real 0.003 user 0.002 sys 0.001
|
||||
|
||||
// Check database size
|
||||
// ls -lh pb_data/data.db
|
||||
|
||||
// Vacuum to reclaim space after deletes
|
||||
// sqlite3 pb_data/data.db "VACUUM;"
|
||||
```
|
||||
|
||||
**When to consider alternatives:**
|
||||
|
||||
Consider migrating from single PocketBase if:
|
||||
- Write throughput consistently > 1000/sec needed
|
||||
- Database size > 100GB
|
||||
- Complex transactions across tables
|
||||
- Multi-region deployment required
|
||||
|
||||
**Custom SQLite driver (advanced):**
|
||||
|
||||
PocketBase supports custom SQLite drivers via `DBConnect`. The CGO driver (`mattn/go-sqlite3`) can offer better performance for some workloads and enables extensions like ICU and FTS5. This requires a custom PocketBase build:
|
||||
|
||||
```go
|
||||
// main.go (custom PocketBase build with CGO driver)
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/pocketbase/dbx"
|
||||
"github.com/pocketbase/pocketbase"
|
||||
_ "github.com/mattn/go-sqlite3" // CGO SQLite driver
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := pocketbase.NewWithConfig(pocketbase.Config{
|
||||
// Called twice: once for data.db, once for auxiliary.db
|
||||
DBConnect: func(dbPath string) (*dbx.DB, error) {
|
||||
return dbx.Open("sqlite3", dbPath)
|
||||
},
|
||||
})
|
||||
|
||||
if err := app.Start(); err != nil {
|
||||
panic(err)
|
||||
}
|
||||
}
|
||||
// Build with: CGO_ENABLED=1 go build
|
||||
```
|
||||
|
||||
Note: CGO requires C compiler toolchain and cannot be cross-compiled as easily as pure Go.
|
||||
|
||||
**Scaling options:**
|
||||
1. **Read replicas**: Litestream for SQLite replication
|
||||
2. **Sharding**: Multiple PocketBase instances by tenant/feature
|
||||
3. **Caching**: Redis/Memcached for read-heavy loads
|
||||
4. **Alternative backend**: If requirements exceed SQLite, evaluate PostgreSQL-based frameworks

title: Compose Hooks, Transactions, Routing, and Enrich in One Request Flow

## Compose Hooks, Transactions, Routing, and Enrich in One Request Flow
|
||||
|
||||
The atomic rules (`ext-hooks-chain`, `ext-transactions`, `ext-routing-custom`, `ext-hooks-record-vs-request`, `ext-filesystem`, `ext-filter-binding-server`) each teach a single trap. Real extending code touches **all of them in the same handler**. This rule walks through one complete request flow and annotates **which app instance is active at each layer** - the single most common source of extending bugs is reaching for the wrong one.
|
||||
|
||||
### The flow
|
||||

```
|
||||
|
||||
### The cheat sheet: "which app am I holding?"
|
||||
|
||||
| Where you are | Use | Why |
|
||||
|---|---|---|
|
||||
| Top of a route handler (`func(e *core.RequestEvent)`) | `e.App` | Framework's top-level app; same object the server started with |
|
||||
| Inside `RunInTransaction(func(txApp) { ... })` | `txApp` **only** | Capturing the outer app deadlocks on the SQLite writer lock |
|
||||
| Inside a record hook fired from a `Save` inside a tx | `e.App` | The framework has already rebound `e.App` to `txApp` for you |
|
||||
| Inside a record hook fired from a non-tx `Save` | `e.App` | Same identifier, same rules, just points to the top-level app |
|
||||
| Inside `OnRecordEnrich` | `e.App` | Runs during response serialization, **after** the tx has committed |
|
||||
| Inside a `app.Cron()` callback | captured `app` / `se.App` | Cron has no per-run scoped app; wrap in `RunInTransaction` if you need atomicity |
|
||||
| Inside a migration function | the `app` argument | `m.Register(func(app core.App) error { ... })` - already transactional |
|
||||
|
||||
### Error propagation in the chain
|
||||
|
||||
- `return err` inside `RunInTransaction` → **rolls back everything**, including any audit records written by hooks that fired from nested `Save` calls.
|
||||
- `return err` from a hook handler → propagates back through the `Save` call → propagates out of the tx closure → rolls back.
|
||||
- **Not** calling `e.Next()` in a hook → the chain is broken **silently**. The framework's own post-save work (realtime broadcast, enrich pass, activity log) is skipped but no error is reported.
|
||||
- A panic inside the tx closure is recovered by PocketBase, the tx rolls back, and the panic is converted to a 500 response.
|
||||
- A panic inside a cron callback is recovered and logged - it does **not** take down the process.
|
||||
|
||||
### When NOT to compose this much
|
||||
|
||||
This example is realistic but also the ceiling of what should live in a single handler. If you find yourself stacking six concerns in one route, consider splitting the logic into a service function that takes `txApp` as a parameter and is called by the route. The same function is then reusable from cron jobs, migrations, and tests.

|
||||
## Schedule Recurring Jobs with the Builtin Cron Scheduler
|
||||
|
||||
PocketBase includes a cron scheduler that starts automatically with `serve`. Register jobs before calling `app.Start()` (Go) or at the top level of a `pb_hooks` file (JSVM). Each job runs in its own goroutine and receives a standard cron expression.
|
||||
|
||||
**Incorrect (external timer, blocking hook, replacing system jobs):**
|
||||
|
||||
```go
|
||||
// ❌ Using a raw Go timer instead of the app cron – misses lifecycle management
|
||||
go func() {
|
||||
for range time.Tick(2 * time.Minute) {
|
||||
log.Println("cleanup")
|
||||
}
|
||||
}()
|
||||
|
||||
// ❌ Blocking inside a hook instead of scheduling
|
||||
app.OnServe().BindFunc(func(se *core.ServeEvent) error {
|
||||
for {
|
||||
time.Sleep(2 * time.Minute)
|
||||
log.Println("cleanup") // ❌ blocks the hook and never returns se.Next()
|
||||
}
|
||||
})
|
||||
|
||||
// ❌ Removing all cron jobs wipes PocketBase's own log-cleanup and auto-backup jobs
|
||||
app.Cron().RemoveAll()
|
||||
```
|
||||
|
||||
```javascript
|
||||
// ❌ JSVM: using setTimeout – not supported in the embedded goja engine
|
||||
setTimeout(() => console.log("run"), 120_000); // ReferenceError
|
||||
```
|
||||
|
||||
**Correct – Go:**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
|
||||
"github.com/pocketbase/pocketbase"
|
||||
"github.com/pocketbase/pocketbase/core"
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := pocketbase.New()
|
||||
|
||||
// Register before app.Start() so the scheduler knows about the job at launch.
|
||||
// MustAdd panics on an invalid cron expression (use Add if you prefer an error return).
|
||||
app.Cron().MustAdd("cleanup-drafts", "0 3 * * *", func() {
|
||||
// Runs every day at 03:00 UTC in its own goroutine.
|
||||
// Use app directly here (not e.App) because this is not inside a hook.
|
||||
records, err := app.FindAllRecords("posts",
|
||||
core.FilterData("status = 'draft' && created < {:cutoff}"),
|
||||
)
|
||||
if err != nil {
|
||||
app.Logger().Error("cron cleanup-drafts", "err", err)
|
||||
return
|
||||
}
|
||||
for _, r := range records {
|
||||
if err := app.Delete(r); err != nil {
|
||||
app.Logger().Error("cron delete", "id", r.Id, "err", err)
|
||||
}
|
||||
}
|
||||
})
|
||||
|
||||
// Remove a job by ID (e.g. during a feature flag toggle)
|
||||
// app.Cron().Remove("cleanup-drafts")
|
||||
|
||||
if err := app.Start(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Correct – JSVM:**
|
||||
|
||||
```javascript
|
||||
// pb_hooks/crons.pb.js
|
||||
/// <reference path="../pb_data/types.d.ts" />
|
||||
|
||||
// Top-level cronAdd() registers the job at hook-load time.
|
||||
// The handler runs in its own goroutine and has access to $app.
|
||||
cronAdd("notify-unpublished", "*/30 * * * *", () => {
|
||||
// Runs every 30 minutes
|
||||
const records = $app.findAllRecords("posts",
|
||||
$dbx.hashExp({ status: "draft" })
|
||||
);
|
||||
console.log(`Found ${records.length} unpublished posts`);
|
||||
});
|
||||
|
||||
// Remove a registered job by ID (useful in tests or feature toggles)
|
||||
// cronRemove("notify-unpublished");
|
||||
```
|
||||
|
||||
**Cron expression reference:**
|
||||
|
||||
```
|
||||
┌─── minute (0 - 59)
|
||||
│ ┌── hour (0 - 23)
|
||||
│ │ ┌─ day-of-month (1 - 31)
|
||||
│ │ │ ┌ month (1 - 12)
|
||||
│ │ │ │ ┌ day-of-week (0 - 6, Sunday = 0)
|
||||
│ │ │ │ │
|
||||
* * * * *
|
||||
|
||||
Examples:
|
||||
*/2 * * * * every 2 minutes
|
||||
0 3 * * * daily at 03:00
|
||||
0 0 * * 0 weekly on Sunday midnight
|
||||
@hourly macro equivalent to 0 * * * *
|
||||
```
|
||||
|
||||
**Key rules:**
|
||||
- System jobs use the `__pb*__` ID prefix (e.g. `__pbLogsCleanup__`). Never call `RemoveAll()` or use that prefix for your own jobs.
|
||||
- All registered cron jobs are visible and can be manually triggered from _Dashboard > Settings > Crons_.
|
||||
- JSVM handlers have access to `$app` but **not** to outer-scope variables (see JSVM scope rule).
|
||||
- Go jobs can use `app` directly (not `e.App`) because they run outside the hook/transaction context.

title: Always Close the Filesystem Handle Returned by NewFilesystem
|
||||
impact: HIGH
|
||||
impactDescription: Leaked filesystem clients keep S3 connections and file descriptors open until the process exits
|
||||
tags: filesystem, extending, files, s3, NewFilesystem, close
|
||||
---
|
||||
|
||||
## Always Close the Filesystem Handle Returned by NewFilesystem
|
||||
|
||||
`app.NewFilesystem()` (Go) and `$app.newFilesystem()` (JS) return a filesystem client backed by either the local disk or S3, depending on the app settings. **The caller owns the handle** and must close it - there is no finalizer and no automatic pooling. Leaking handles leaks TCP connections to S3 and file descriptors on disk, and eventually the server will stop accepting uploads.
|
||||
|
||||
PocketBase also ships a second client: `app.NewBackupsFilesystem()` for the backups bucket/directory, with the same ownership rules.
|
||||
|
||||
**Incorrect (no close, raw bytes buffered in memory):**
|
||||
|
||||
```go
|
||||
// ❌ Forgets to close fs - connection leaks
|
||||
func downloadAvatar(app core.App, key string) ([]byte, error) {
|
||||
fs, err := app.NewFilesystem()
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
// ❌ no defer fs.Close()
|
||||
|
||||
// ❌ GetFile loads the whole file into a reader; reading it all into a
|
||||
// byte slice defeats streaming for large files
|
||||
r, err := fs.GetFile(key)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
defer r.Close()
|
||||
return io.ReadAll(r)
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (defer Close, stream to the HTTP response):**
|
||||
|
||||
```go
|
||||
func serveAvatar(app core.App, key string) echo.HandlerFunc {
|
||||
return func(e *core.RequestEvent) error {
|
||||
fs, err := app.NewFilesystem()
|
||||
if err != nil {
|
||||
return e.InternalServerError("filesystem init failed", err)
|
||||
}
|
||||
defer fs.Close() // REQUIRED
|
||||
|
||||
// Serve directly from the filesystem - handles ranges, content-type,
|
||||
// and the X-Accel-Redirect / X-Sendfile headers when available
|
||||
return fs.Serve(e.Response, e.Request, key, "avatar.jpg")
|
||||
}
|
||||
}
|
||||
|
||||
// Uploading a local file to the PocketBase-managed filesystem
|
||||
func importAvatar(app core.App, record *core.Record, path string) error {
|
||||
f, err := filesystem.NewFileFromPath(path)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
record.Set("avatar", f) // assignment + app.Save() persist it
|
||||
return app.Save(record)
|
||||
}
|
||||
```
|
||||
|
||||
```javascript
|
||||
// JSVM - file factories live on the $filesystem global
|
||||
const file1 = $filesystem.fileFromPath("/tmp/import.jpg");
|
||||
const file2 = $filesystem.fileFromBytes(new Uint8Array([0xff, 0xd8]), "logo.jpg");
|
||||
const file3 = $filesystem.fileFromURL("https://example.com/a.jpg");
|
||||
|
||||
// Assigning to a record field triggers upload on save
|
||||
record.set("avatar", file1);
|
||||
$app.save(record);
|
||||
|
||||
// Low-level client - MUST be closed
|
||||
const fs = $app.newFilesystem();
|
||||
try {
|
||||
const list = fs.list("thumbs/");
|
||||
for (const obj of list) {
|
||||
console.log(obj.key, obj.size);
|
||||
}
|
||||
} finally {
|
||||
fs.close(); // REQUIRED
|
||||
}
|
||||
```
|
||||
|
||||
**Rules:**
|
||||
- `defer fs.Close()` **immediately** after a successful `NewFilesystem()` / `NewBackupsFilesystem()` call (Go). In JS, wrap in `try { ... } finally { fs.close() }`.
|
||||
- Prefer the high-level record-field API (`record.Set("field", file)` + `app.Save`) over direct `fs.Upload` calls - it handles thumbs regeneration, orphan cleanup, and hook integration.
|
||||
- File factory functions (`filesystem.NewFileFromPath`, `NewFileFromBytes`, `NewFileFromURL` / JS `$filesystem.fileFromPath|Bytes|URL`) capture their input; they do not stream until save.
|
||||
- `fileFromURL` performs an HTTP GET and loads the body into memory - not appropriate for large files.
|
||||
- Do not share a single long-lived `fs` across unrelated requests; the object is cheap to create per request.

title: Bind User Input in Server-Side Filters with {:placeholder} Params
|
||||
impact: CRITICAL
|
||||
impactDescription: String-concatenating user input into filter expressions is a direct injection vulnerability
|

tags: extending, filter, injection, security, FindRecordsByFilter, dbx
|

---
|
||||
|
||||
## Bind User Input in Server-Side Filters with {:placeholder} Params
|
||||
|
||||
Server-side helpers like `FindFirstRecordByFilter`, `FindRecordsByFilter`, and `dbx.NewExp` accept a filter string that supports `{:name}` placeholders. **Never** concatenate user input into the filter - PocketBase's filter parser has its own syntax that is sensitive to quoting, and concatenation allows an attacker to alter the query (same class of bug as SQL injection).
|
||||
|
||||
**Incorrect (string interpolation - filter injection):**
|
||||
|
||||
```go
|
||||
// ❌ attacker sets email to: x' || 1=1 || email='
|
||||
// resulting filter bypasses the intended match entirely
|
||||
email := e.Request.URL.Query().Get("email")
|
||||
record, err := app.FindFirstRecordByFilter(
|
||||
"users",
|
||||
"email = '"+email+"' && verified = true", // ❌
|
||||
)
|
||||
```
|
||||
|
||||
```javascript
|
||||
// JSVM - same class of bug
|
||||
const email = e.request.url.query().get("email");
|
||||
const record = $app.findFirstRecordByFilter(
|
||||
"users",
|
||||
`email = '${email}' && verified = true`, // ❌
|
||||
);
|
||||
```
|
||||
|
||||
**Correct (named placeholders + params map):**
|
||||
|
||||
```go
|
||||
import "github.com/pocketbase/dbx"
|
||||
|

|

```
|

|
||||
```javascript
|

// JSVM - second argument after the filter is the params object
|
||||
const record = $app.findFirstRecordByFilter(
|
||||
"users",
|
||||
"email = {:email} && verified = true",
|
||||
{ email: email },
|
||||
);

const recs = $app.findRecordsByFilter(
|

"posts",
|

"author = {:author} && status = {:status}",
|
||||
"-created", 20, 0,
|
||||
{ author: e.auth.id, status: "published" },
|
||||
);
|
||||
```
|
||||
|
||||
**Rules:**
|
||||
- Placeholder syntax is `{:name}` inside the filter string, and the value is supplied via `dbx.Params{"name": value}` (Go) or a plain object (JS).
|
||||
- The same applies to `dbx.NewExp("LOWER(email) = {:email}", dbx.Params{"email": email})` when writing raw `dbx` expressions.
|
||||
- Passing a `types.DateTime` / `DateTime` value binds it correctly - do not stringify dates manually.
|
||||
- `nil` / `null` binds as SQL NULL; use `field = null` or `field != null` in the filter expression.
|
||||
- The filter grammar is the same as used by collection API rules - consult [Filter Syntax](https://pocketbase.io/docs/api-rules-and-filters/#filters) for operators.

title: Use DBConnect Only When You Need a Custom SQLite Driver

|
||||
## Use DBConnect Only When You Need a Custom SQLite Driver
|
||||
|
||||
PocketBase ships with the **pure-Go** `modernc.org/sqlite` driver (no CGO required). Only reach for a custom driver when you specifically need SQLite extensions like ICU, FTS5, or spatialite that the default driver doesn't expose. `DBConnect` is called **twice** — once for `pb_data/data.db` and once for `pb_data/auxiliary.db` — so driver registration and PRAGMAs must be idempotent.
|
||||
|
||||
**Incorrect (unnecessary custom driver, mismatched builder, CGO without justification):**
|
||||
|
||||
```go
|
||||
// ❌ Adding a CGO dependency with no need for extensions
|
||||
import _ "github.com/mattn/go-sqlite3"
|
||||
|
||||
func main() {
|
||||
app := pocketbase.NewWithConfig(pocketbase.Config{
|
||||
DBConnect: func(dbPath string) (*dbx.DB, error) {
|
||||
// ❌ "sqlite3" builder name used but "pb_sqlite3" driver was registered —
|
||||
// or vice versa — causing "unknown driver" / broken query generation
|
||||
return dbx.Open("sqlite3", dbPath)
|
||||
},
|
||||
})
|
||||
if err := app.Start(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Correct (mattn/go-sqlite3 with CGO — proper PRAGMA init hook and builder map entry):**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|

"database/sql"

|
||||
|

func init() {
|
||||
// Use a unique driver name to avoid conflicts with other packages.
|
||||
// sql.Register panics if called twice with the same name, so put it in init().

||||
sql.Register("pb_sqlite3", &sqlite3.SQLiteDriver{
|
||||

|
||||
return err
|

},
|

})
|
||||
// Mirror the sqlite3 query builder so PocketBase generates correct SQL
|
||||
dbx.BuilderFuncMap["pb_sqlite3"] = dbx.BuilderFuncMap["sqlite3"]
|
||||
}
|
||||
|

func main() {
|

app := pocketbase.NewWithConfig(pocketbase.Config{
|

}
|

```
|

|

**Conditional custom driver with default fallback:**
|
||||
|
||||
```go
|
||||
app := pocketbase.NewWithConfig(pocketbase.Config{
|
||||
DBConnect: func(dbPath string) (*dbx.DB, error) {
|
||||
// Use custom driver only for the main data file; fall back for auxiliary
|
||||
if strings.HasSuffix(dbPath, "data.db") {
|
||||
return dbx.Open("pb_sqlite3", dbPath)
|
||||
}
|
||||
return core.DefaultDBConnect(dbPath)
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
**Decision guide:**
|
||||
|
||||
| Need | Driver |
|
||||
|------|--------|
|
||||
| Default (no extensions) | Built-in `modernc.org/sqlite` — no `DBConnect` config needed |
|
||||
| FTS5, ICU, spatialite | `mattn/go-sqlite3` (CGO) or `ncruces/go-sqlite3` (WASM, no CGO) |
|
||||
| Reduce binary size | `go build -tags no_default_driver` to exclude the default driver (~4 MB saved) |
|
||||
| Conditional fallback | Call `core.DefaultDBConnect(dbPath)` inside your `DBConnect` function |

title: Version Your Schema with Go Migrations

|

## Version Your Schema with Go Migrations
|
||||
|
||||
PocketBase ships with a `migratecmd` plugin that generates versioned `.go` migration files, applies them automatically on `serve`, and lets you roll back with `migrate down`. Because the files are compiled into your binary, no extra migration tool is needed.
|
||||
|
||||
**Incorrect (one-off SQL or dashboard changes in production):**
|
||||
|
||||
```go
|
||||
// ❌ Running raw SQL directly at startup without a migration file –
|
||||
// the change is applied every restart and has no rollback path.
|
||||
app.OnServe().BindFunc(func(se *core.ServeEvent) error {
|
||||
_, err := app.DB().NewQuery(
|
||||
"ALTER TABLE posts ADD COLUMN summary TEXT DEFAULT ''",
|
||||
).Execute()
|
||||
return err
|
||||
})
|
||||
|
||||
// ❌ Forgetting to import the migrations package means
|
||||
// registered migrations are never executed.
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/pocketbase/pocketbase"
|
||||
"github.com/pocketbase/pocketbase/plugins/migratecmd"
|
||||
// _ "myapp/migrations" ← omitted: migrations never run
|
||||
)
|
||||
```
|
||||
|
||||
**Correct (register migratecmd, import migrations package):**
|
||||
|
||||
```go
|
||||
// main.go
|
||||
package main
|
||||
|
||||
import (
|
||||
"log"
|
||||
"os"
|
||||
|
||||
"github.com/pocketbase/pocketbase"
|
||||
"github.com/pocketbase/pocketbase/plugins/migratecmd"
|
||||
"github.com/pocketbase/pocketbase/tools/osutils"
|
||||
|
||||
// Import side-effects only; this registers all init() migrations.
|
||||
_ "myapp/migrations"
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := pocketbase.New()
|
||||
|
||||
migratecmd.MustRegister(app, app.RootCmd, migratecmd.Config{
|
||||
// Automigrate generates a new .go file whenever you make
|
||||
// collection changes in the Dashboard (dev-only).
|
||||
Automigrate: osutils.IsProbablyGoRun(),
|
||||
})
|
||||
|
||||
if err := app.Start(); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Create and write a migration:**
|
||||
|
||||
```bash
|
||||
# Create a blank migration file in ./migrations/
|
||||
go run . migrate create "add_summary_to_posts"
|
||||
```
|
||||
|
||||
```go
|
||||
// migrations/1687801090_add_summary_to_posts.go
|
||||
package migrations
|
||||
|
||||
import (
|
||||
"github.com/pocketbase/pocketbase/core"
|
||||
m "github.com/pocketbase/pocketbase/migrations"
|
||||
)
|
||||
|
||||
func init() {
|
||||
m.Register(func(app core.App) error {
|
||||
// app is a transactional App instance – safe to use directly.
|
||||
collection, err := app.FindCollectionByNameOrId("posts")
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
collection.Fields.Add(&core.TextField{
|
||||
Name: "summary",
|
||||
Required: false,
|
||||
})
|
||||
|
||||
return app.Save(collection)
|
||||
}, func(app core.App) error {
|
||||
// Optional rollback
|
||||
collection, err := app.FindCollectionByNameOrId("posts")
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
collection.Fields.RemoveByName("summary")
|
||||
return app.Save(collection)
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
**Snapshot all collections (useful for a fresh repo):**
|
||||
|
||||
```bash
|
||||
# Generates a migration file that recreates your current schema from scratch.
|
||||
go run . migrate collections
|
||||
```
|
||||
|
||||
**Clean up dev migration history:**
|
||||
|
||||
```bash
|
||||
# Remove _migrations table entries that have no matching .go file.
|
||||
# Run after squashing or deleting intermediate dev migration files.
|
||||
go run . migrate history-sync
|
||||
```
|
||||
|
||||
**Apply / roll back manually:**
|
||||
|
||||
```bash
|
||||
go run . migrate up # apply all unapplied migrations
|
||||
go run . migrate down 1 # revert the last applied migration
|
||||
```
|
||||
|
||||
**Key details:**
|
||||
- Migration functions receive a **transactional** `core.App` – treat it as the database source of truth. Never use the outer `app` variable inside migration callbacks.
|
||||
- New unapplied migrations run automatically on every `serve` start – no manual step in production.
|
||||
- `Automigrate: osutils.IsProbablyGoRun()` limits auto-generation to `go run` (development) and prevents accidental file creation in production binaries.
|
||||
- Prefer the collection API (`app.Save(collection)`) over raw SQL `ALTER TABLE` so PocketBase's internal schema cache stays consistent.
|
||||
- Commit all generated `.go` files to version control; do **not** commit `pb_data/`.
