**Welcome to the skills folder!** This is where all 179+ specialized AI skills live.
|
||||
|
||||
## 📂 目录结构
|
||||
## 🤔 What Are Skills?
|
||||
|
||||
Skills are specialized instruction sets that teach AI assistants how to handle specific tasks. Think of them as expert knowledge modules that your AI can load on-demand.
|
||||
|
||||
**Simple analogy:** Just like you might consult different experts (a designer, a security expert, a marketer), skills let your AI become an expert in different areas when you need them.
|
||||

|
||||
|
||||
## How to Use Skills
|
||||
|
||||
### Step 1: Make sure skills are installed
|
||||
Skills should be in your `.agent/skills/` directory (or `.claude/skills/`, `.gemini/skills/`, etc.)
|
||||
|
||||
### Step 2: Invoke a skill in your AI chat
|
||||
Use the `@` symbol followed by the skill name:
|
||||
|
||||
```
|
||||
@brainstorming help me design a todo app
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```
|
||||
@stripe-integration add payment processing to my app
|
||||
```
|
||||
|
||||
### Step 3: The AI becomes an expert
|
||||
The AI loads that skill's knowledge and helps you with specialized expertise!

# Agent Memory Skill
|
||||
|
||||
This skill provides a persistent, searchable memory bank that automatically syncs with project documentation. It runs as an MCP server to allow reading/writing/searching of long-term memories.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Node.js (v18+)
|
||||
|
||||
## Setup
|
||||
|
||||
1. **Clone the Repository**:
|
||||
Clone the `agentMemory` project into your agent's workspace or a parallel directory:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/webzler/agentMemory.git .agent/skills/agent-memory
|
||||
```
|
||||
|
||||
2. **Install Dependencies**:
|
||||
|
||||
```bash
|
||||
cd .agent/skills/agent-memory
|
||||
npm install
|
||||
npm run compile
|
||||
```
|
||||
|
||||
3. **Start the MCP Server**:
|
||||
Use the helper script to activate the memory bank for your current project:
|
||||
|
||||
```bash
|
||||
npm run start-server <project_id> <absolute_path_to_target_workspace>
|
||||
```
|
||||
|
||||
_Example for current directory:_
|
||||
|
||||
```bash
|

# API Documentation Generator
|
||||
|
||||
## Overview
|
||||
|
||||
Automatically generate clear, comprehensive API documentation from your codebase. This skill helps you create professional documentation that includes endpoint descriptions, request/response examples, authentication details, error handling, and usage guidelines.
|
||||
|
||||
Perfect for REST APIs, GraphQL APIs, and WebSocket APIs.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
- Use when you need to document a new API
|
||||
- Use when updating existing API documentation
|
||||
- Use when your API lacks clear documentation
|
||||
- Use when onboarding new developers to your API
|
||||
- Use when preparing API documentation for external users
|
||||
- Use when creating OpenAPI/Swagger specifications
|
||||
|
||||
## How It Works
|
||||
|
||||
### Step 1: Analyze the API Structure
|
||||
|
||||
First, I'll examine your API codebase to understand:
|
||||
- Available endpoints and routes
|
||||
- HTTP methods (GET, POST, PUT, DELETE, etc.)
|
||||
- Request parameters and body structure
|
||||
- Response formats and status codes
|
||||
- Authentication and authorization requirements
|
||||
- Error handling patterns
|
||||
|
||||
### Step 2: Generate Endpoint Documentation
|
||||
|
||||
For each endpoint, I'll create documentation including:
|
||||
|
||||
**Endpoint Details:**
|
||||
- HTTP method and URL path
|
||||
- Brief description of what it does
|
||||
- Authentication requirements
|
||||
- Rate limiting information (if applicable)
|
||||
|
||||
**Request Specification:**
|
||||
- Path parameters
|
||||
- Query parameters
|
||||
- Request headers
|
||||
- Request body schema (with types and validation rules)
|
||||
|
||||
**Response Specification:**
|
||||
- Success response (status code + body structure)
|
||||
- Error responses (all possible error codes)
|
||||
- Response headers
|
||||
|
||||
**Code Examples:**
|
||||
- cURL command
|
||||
- JavaScript/TypeScript (fetch/axios)
|
||||
- Python (requests)
|
||||
- Other languages as needed
|
||||
|
||||
### Step 3: Add Usage Guidelines
|
||||
|
||||
I'll include:
|
||||
- Getting started guide
|
||||
- Authentication setup
|
||||
- Common use cases
|
||||
- Best practices
|
||||
- Rate limiting details
|
||||
- Pagination patterns
|
||||
- Filtering and sorting options
|
||||
|
||||
### Step 4: Document Error Handling
|
||||
|
||||
Clear error documentation including:
|
||||
- All possible error codes
|
||||
- Error message formats
|
||||
- Troubleshooting guide
|
||||
- Common error scenarios and solutions
|
||||
|
||||
### Step 5: Create Interactive Examples
|
||||
|
||||
Where possible, I'll provide:
|
||||
- Postman collection
|
||||
- OpenAPI/Swagger specification
|
||||
- Interactive code examples
|
||||
- Sample responses
|
||||

|
||||
|
||||
### Example 3: Authentication Documentation
|
||||
|
||||
```markdown
|
||||
## Authentication
|
||||
|
||||
All API requests require authentication using Bearer tokens.
|
||||
|
||||
### Getting a Token
|
||||
|
||||
**Endpoint:** `POST /api/v1/auth/login`
|
||||
|
||||
**Request:**
|
||||
\`\`\`json
|
||||
{
|
||||
"email": "user@example.com",
|
||||
"password": "your-password"
|
||||
}
|
||||
\`\`\`
|
||||
|
||||
**Response:**
|
||||
\`\`\`json
|
||||
{
|
||||
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
|
||||
"expiresIn": 3600,
|
||||
"refreshToken": "refresh_token_here"
|
||||
}
|
||||
\`\`\`
|
||||
|
||||
### Using the Token
|
||||
|
||||
Include the token in the Authorization header:
|
||||
|
||||
\`\`\`
|
||||
Authorization: Bearer YOUR_TOKEN
|
||||
\`\`\`
|
||||
|
||||
### Token Expiration
|
||||
|
||||
Tokens expire after 1 hour. Use the refresh token to get a new access token:
|
||||
|
||||
**Endpoint:** `POST /api/v1/auth/refresh`
|
||||
|
||||
**Request:**
|
||||
\`\`\`json
|
||||
{
|
||||
"refreshToken": "refresh_token_here"
|
||||
}
|
||||
\`\`\`
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### ✅ Do This
|
||||
|
||||
- **Be Consistent** - Use the same format for all endpoints
|
||||
- **Include Examples** - Provide working code examples in multiple languages
|
||||
- **Document Errors** - List all possible error codes and their meanings
|
||||
- **Show Real Data** - Use realistic example data, not "foo" and "bar"
|
||||
- **Explain Parameters** - Describe what each parameter does and its constraints
|
||||
- **Version Your API** - Include version numbers in URLs (/api/v1/)
|
||||
- **Add Timestamps** - Show when documentation was last updated
|
||||
- **Link Related Endpoints** - Help users discover related functionality
|
||||
- **Include Rate Limits** - Document any rate limiting policies
|
||||
- **Provide Postman Collection** - Make it easy to test your API
|
||||
|
||||
### ❌ Don't Do This
|
||||
|
||||
- **Don't Skip Error Cases** - Users need to know what can go wrong
|
||||
- **Don't Use Vague Descriptions** - "Gets data" is not helpful
|
||||
- **Don't Forget Authentication** - Always document auth requirements
|
||||
- **Don't Ignore Edge Cases** - Document pagination, filtering, sorting
|
||||
- **Don't Leave Examples Broken** - Test all code examples
|
||||
- **Don't Use Outdated Info** - Keep documentation in sync with code
|
||||
- **Don't Overcomplicate** - Keep it simple and scannable
|
||||
- **Don't Forget Response Headers** - Document important headers
|
||||
|
||||

|
||||
**Solution:**
|
||||
- Generate docs from code comments/annotations
|
||||
- Use tools like Swagger/OpenAPI
|
||||
- Add API tests that validate documentation
|
||||
- Review docs with every API change
|
||||
|
||||
### Problem: Missing Error Documentation
|
||||
**Symptoms:** Users don't know how to handle errors, support tickets increase
|
||||
**Solution:**
|
||||
- Document every possible error code
|
||||
- Provide clear error messages
|
||||
- Include troubleshooting steps
|
||||
- Show example error responses
|
||||
|
||||

||||
**Symptoms:** Users can't get started, frustration increases
|
||||
**Solution:**
|
||||
- Test every code example
|
||||
- Use real, working endpoints
|
||||
- Include complete examples (not fragments)
|
||||
- Provide a sandbox environment
|
||||
|
||||
### Problem: Unclear Parameter Requirements
|
||||
**Symptoms:** Users send invalid requests, validation errors
|
||||
**Solution:**
|
||||
- Mark required vs optional clearly
|
||||
- Document data types and formats
|
||||
- Show validation rules
|
||||
- Provide example values
|
||||
|
||||
## Tools and Formats
|
||||
|
||||

||||
Generate interactive documentation:
|
||||
```yaml
|
||||
openapi: 3.0.0
|
||||
info:
|
||||
title: My API
|
||||
version: 1.0.0
|
||||
paths:
|
||||
/users:
|
||||
post:
|
||||
summary: Create a new user
|
||||

# Backend Development Patterns
|
||||
|
||||
Backend architecture patterns and best practices for scalable server-side applications.
|
||||
|
||||
## API Design Patterns
|
||||
|
||||
### RESTful API Structure
|
||||
|
||||
```typescript
|
||||
// ✅ Resource-based URLs
|
||||
GET /api/markets # List resources
|
||||
GET /api/markets/:id # Get single resource
|
||||
POST /api/markets # Create resource
|
||||
PUT /api/markets/:id # Replace resource
|
||||
PATCH /api/markets/:id # Update resource
|
||||
DELETE /api/markets/:id # Delete resource
|
||||
|
||||
// ✅ Query parameters for filtering, sorting, pagination
|
||||
GET /api/markets?status=active&sort=volume&limit=20&offset=0
|
||||
```
|
||||
|
||||
### Repository Pattern
|
||||
|
||||
```typescript
|
||||
// Abstract data access logic
|
||||
interface MarketRepository {
|
||||
findAll(filters?: MarketFilters): Promise<Market[]>
|
||||
findById(id: string): Promise<Market | null>
|
||||
create(data: CreateMarketDto): Promise<Market>
|
||||
update(id: string, data: UpdateMarketDto): Promise<Market>
|
||||
delete(id: string): Promise<void>
|
||||
}
|
||||
|
||||
class SupabaseMarketRepository implements MarketRepository {
|
||||
async findAll(filters?: MarketFilters): Promise<Market[]> {
|
||||
let query = supabase.from('markets').select('*')
|
||||
|
||||
if (filters?.status) {
|
||||
query = query.eq('status', filters.status)
|
||||
}
|
||||
|
||||
if (filters?.limit) {
|
||||
query = query.limit(filters.limit)
|
||||
}
|
||||
|
||||
const { data, error } = await query
|
||||
|
||||
if (error) throw new Error(error.message)
|
||||
return data
|
||||
}
|
||||
|
||||
// Other methods...
|
||||
}
|
||||
```
|
||||
|
||||
### Service Layer Pattern
|
||||
|
||||
```typescript
|
||||
// Business logic separated from data access
|
||||
class MarketService {
|
||||
constructor(private marketRepo: MarketRepository) {}
|
||||
|
||||
async searchMarkets(query: string, limit: number = 10): Promise<Market[]> {
|
||||
// Business logic
|
||||
const embedding = await generateEmbedding(query)
|
||||
const results = await this.vectorSearch(embedding, limit)
|
||||
|
||||
// Fetch full data
|
||||
const markets = await this.marketRepo.findByIds(results.map(r => r.id))
|
||||
|
||||
// Sort by similarity
|
||||
return markets.sort((a, b) => {
|
||||
const scoreA = results.find(r => r.id === a.id)?.score || 0
|
||||
const scoreB = results.find(r => r.id === b.id)?.score || 0
|
||||
return scoreA - scoreB
|
||||
})
|
||||
}
|
||||
|
||||
private async vectorSearch(embedding: number[], limit: number) {
|
||||
// Vector search implementation
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Middleware Pattern
|
||||
|
||||
```typescript
|
||||
// Request/response processing pipeline
|
||||
export function withAuth(handler: NextApiHandler): NextApiHandler {
|
||||
return async (req, res) => {
|
||||
const token = req.headers.authorization?.replace('Bearer ', '')
|
||||
|
||||
if (!token) {
|
||||
return res.status(401).json({ error: 'Unauthorized' })
|
||||
}
|
||||
|
||||
try {
|
||||
const user = await verifyToken(token)
|
||||
req.user = user
|
||||
return handler(req, res)
|
||||
} catch (error) {
|
||||
return res.status(401).json({ error: 'Invalid token' })
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
export default withAuth(async (req, res) => {
|
||||
// Handler has access to req.user
|
||||
})
|
||||
```
|
||||
|
||||
## Database Patterns
|
||||
|
||||
### Query Optimization
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Select only needed columns
|
||||
const { data } = await supabase
|
||||
.from('markets')
|
||||
.select('id, name, status, volume')
|
||||
.eq('status', 'active')
|
||||
.order('volume', { ascending: false })
|
||||
.limit(10)
|
||||
|
||||
// ❌ BAD: Select everything
|
||||
const { data } = await supabase
|
||||
.from('markets')
|
||||
.select('*')
|
||||
```
|
||||
|
||||
### N+1 Query Prevention
|
||||
|
||||
```typescript
|
||||
// ❌ BAD: N+1 query problem
|
||||
const markets = await getMarkets()
|
||||
for (const market of markets) {
|
||||
market.creator = await getUser(market.creator_id) // N queries
|
||||
}
|
||||
|
||||
// ✅ GOOD: Batch fetch
|
||||
const markets = await getMarkets()
|
||||
const creatorIds = markets.map(m => m.creator_id)
|
||||
const creators = await getUsers(creatorIds) // 1 query
|
||||
const creatorMap = new Map(creators.map(c => [c.id, c]))
|
||||
|
||||
markets.forEach(market => {
|
||||
market.creator = creatorMap.get(market.creator_id)
|
||||
})
|
||||
```
|
||||
|
||||
### Transaction Pattern
|
||||
|
||||
```typescript
|
||||
async function createMarketWithPosition(
|
||||
marketData: CreateMarketDto,
|
||||
positionData: CreatePositionDto
|
||||
) {
|
||||
// Use Supabase transaction
|
||||
const { data, error } = await supabase.rpc('create_market_with_position', {
|
||||
market_data: marketData,
|
||||
position_data: positionData
|
||||
})
|
||||
|
||||
if (error) throw new Error('Transaction failed')
|
||||
return data
|
||||
}
|
||||
|
||||
// SQL function in Supabase
|
||||
CREATE OR REPLACE FUNCTION create_market_with_position(
|
||||
market_data jsonb,
|
||||
position_data jsonb
|
||||
)
|
||||
RETURNS jsonb
|
||||
LANGUAGE plpgsql
|
||||
AS $$
|
||||
BEGIN
|
||||
-- Start transaction automatically
|
||||
INSERT INTO markets VALUES (market_data);
|
||||
INSERT INTO positions VALUES (position_data);
|
||||
RETURN jsonb_build_object('success', true);
|
||||
EXCEPTION
|
||||
WHEN OTHERS THEN
|
||||
-- Rollback happens automatically
|
||||
RETURN jsonb_build_object('success', false, 'error', SQLERRM);
|
||||
END;
|
||||
$$;
|
||||
```
|
||||
|
||||
## Caching Strategies
|
||||
|
||||
### Redis Caching Layer
|
||||
|
||||
```typescript
|
||||
class CachedMarketRepository implements MarketRepository {
|
||||
constructor(
|
||||
private baseRepo: MarketRepository,
|
||||
private redis: RedisClient
|
||||
) {}
|
||||
|
||||
async findById(id: string): Promise<Market | null> {
|
||||
// Check cache first
|
||||
const cached = await this.redis.get(`market:${id}`)
|
||||
|
||||
if (cached) {
|
||||
return JSON.parse(cached)
|
||||
}
|
||||
|
||||
// Cache miss - fetch from database
|
||||
const market = await this.baseRepo.findById(id)
|
||||
|
||||
if (market) {
|
||||
// Cache for 5 minutes
|
||||
await this.redis.setex(`market:${id}`, 300, JSON.stringify(market))
|
||||
}
|
||||
|
||||
return market
|
||||
}
|
||||
|
||||
async invalidateCache(id: string): Promise<void> {
|
||||
await this.redis.del(`market:${id}`)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Cache-Aside Pattern
|
||||
|
||||
```typescript
|
||||
async function getMarketWithCache(id: string): Promise<Market> {
|
||||
const cacheKey = `market:${id}`
|
||||
|
||||
// Try cache
|
||||
const cached = await redis.get(cacheKey)
|
||||
if (cached) return JSON.parse(cached)
|
||||
|
||||
// Cache miss - fetch from DB
|
||||
const market = await db.markets.findUnique({ where: { id } })
|
||||
|
||||
if (!market) throw new Error('Market not found')
|
||||
|
||||
// Update cache
|
||||
await redis.setex(cacheKey, 300, JSON.stringify(market))
|
||||
|
||||
return market
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling Patterns
|
||||
|
||||
### Centralized Error Handler
|
||||
|
||||
```typescript
|
||||
class ApiError extends Error {
|
||||
constructor(
|
||||
public statusCode: number,
|
||||
public message: string,
|
||||
public isOperational = true
|
||||
) {
|
||||
super(message)
|
||||
Object.setPrototypeOf(this, ApiError.prototype)
|
||||
}
|
||||
}
|
||||
|
||||
export function errorHandler(error: unknown, req: Request): Response {
|
||||
if (error instanceof ApiError) {
|
||||
return NextResponse.json({
|
||||
success: false,
|
||||
error: error.message
|
||||
}, { status: error.statusCode })
|
||||
}
|
||||
|
||||
if (error instanceof z.ZodError) {
|
||||
return NextResponse.json({
|
||||
success: false,
|
||||
error: 'Validation failed',
|
||||
details: error.errors
|
||||
}, { status: 400 })
|
||||
}
|
||||
|
||||
// Log unexpected errors
|
||||
console.error('Unexpected error:', error)
|
||||
|
||||
return NextResponse.json({
|
||||
success: false,
|
||||
error: 'Internal server error'
|
||||
}, { status: 500 })
|
||||
}
|
||||
|
||||
// Usage
|
||||
export async function GET(request: Request) {
|
||||
try {
|
||||
const data = await fetchData()
|
||||
return NextResponse.json({ success: true, data })
|
||||
} catch (error) {
|
||||
return errorHandler(error, request)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Retry with Exponential Backoff
|
||||
|
||||
```typescript
|
||||
async function fetchWithRetry<T>(
|
||||
fn: () => Promise<T>,
|
||||
maxRetries = 3
|
||||
): Promise<T> {
|
||||
let lastError: Error
|
||||
|
||||
for (let i = 0; i < maxRetries; i++) {
|
||||
try {
|
||||
return await fn()
|
||||
} catch (error) {
|
||||
lastError = error as Error
|
||||
|
||||
if (i < maxRetries - 1) {
|
||||
// Exponential backoff: 1s, 2s, 4s
|
||||
const delay = Math.pow(2, i) * 1000
|
||||
await new Promise(resolve => setTimeout(resolve, delay))
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
throw lastError!
|
||||
}
|
||||
|
||||
// Usage
|
||||
const data = await fetchWithRetry(() => fetchFromAPI())
|
||||
```
|
||||
|
||||
## Authentication & Authorization
|
||||
|
||||
### JWT Token Validation
|
||||
|
||||
```typescript
|
||||
import jwt from 'jsonwebtoken'
|
||||
|
||||
interface JWTPayload {
|
||||
userId: string
|
||||
email: string
|
||||
role: 'admin' | 'user'
|
||||
}
|
||||
|
||||
export function verifyToken(token: string): JWTPayload {
|
||||
try {
|
||||
const payload = jwt.verify(token, process.env.JWT_SECRET!) as JWTPayload
|
||||
return payload
|
||||
} catch (error) {
|
||||
throw new ApiError(401, 'Invalid token')
|
||||
}
|
||||
}
|
||||
|
||||
export async function requireAuth(request: Request) {
|
||||
const token = request.headers.get('authorization')?.replace('Bearer ', '')
|
||||
|
||||
if (!token) {
|
||||
throw new ApiError(401, 'Missing authorization token')
|
||||
}
|
||||
|
||||
return verifyToken(token)
|
||||
}
|
||||
|
||||
// Usage in API route
|
||||
export async function GET(request: Request) {
|
||||
const user = await requireAuth(request)
|
||||
|
||||
const data = await getDataForUser(user.userId)
|
||||
|
||||
return NextResponse.json({ success: true, data })
|
||||
}
|
||||
```
|
||||
|
||||
### Role-Based Access Control
|
||||
|
||||
```typescript
|
||||
type Permission = 'read' | 'write' | 'delete' | 'admin'
|
||||
|
||||
interface User {
|
||||
id: string
|
||||
role: 'admin' | 'moderator' | 'user'
|
||||
}
|
||||
|
||||
const rolePermissions: Record<User['role'], Permission[]> = {
|
||||
admin: ['read', 'write', 'delete', 'admin'],
|
||||
moderator: ['read', 'write', 'delete'],
|
||||
user: ['read', 'write']
|
||||
}
|
||||
|
||||
export function hasPermission(user: User, permission: Permission): boolean {
|
||||
return rolePermissions[user.role].includes(permission)
|
||||
}
|
||||
|
||||
export function requirePermission(permission: Permission) {
|
||||
return async (request: Request) => {
|
||||
const user = await requireAuth(request)
|
||||
|
||||
if (!hasPermission(user, permission)) {
|
||||
throw new ApiError(403, 'Insufficient permissions')
|
||||
}
|
||||
|
||||
return user
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
export const DELETE = requirePermission('delete')(async (request: Request) => {
|
||||
// Handler with permission check
|
||||
})
|
||||
```
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
### Simple In-Memory Rate Limiter
|
||||
|
||||
```typescript
|
||||
class RateLimiter {
|
||||
private requests = new Map<string, number[]>()
|
||||
|
||||
async checkLimit(
|
||||
identifier: string,
|
||||
maxRequests: number,
|
||||
windowMs: number
|
||||
): Promise<boolean> {
|
||||
const now = Date.now()
|
||||
const requests = this.requests.get(identifier) || []
|
||||
|
||||
// Remove old requests outside window
|
||||
const recentRequests = requests.filter(time => now - time < windowMs)
|
||||
|
||||
if (recentRequests.length >= maxRequests) {
|
||||
return false // Rate limit exceeded
|
||||
}
|
||||
|
||||
// Add current request
|
||||
recentRequests.push(now)
|
||||
this.requests.set(identifier, recentRequests)
|
||||
|
||||
return true
|
||||
}
|
||||
}
|
||||
|
||||
const limiter = new RateLimiter()
|
||||
|
||||
export async function GET(request: Request) {
|
||||
const ip = request.headers.get('x-forwarded-for') || 'unknown'
|
||||
|
||||
const allowed = await limiter.checkLimit(ip, 100, 60000) // 100 req/min
|
||||
|
||||
if (!allowed) {
|
||||
return NextResponse.json({
|
||||
error: 'Rate limit exceeded'
|
||||
}, { status: 429 })
|
||||
}
|
||||
|
||||
// Continue with request
|
||||
}
|
||||
```
|
||||
|
||||
## Background Jobs & Queues
|
||||
|
||||
### Simple Queue Pattern
|
||||
|
||||
```typescript
|
||||
class JobQueue<T> {
|
||||
private queue: T[] = []
|
||||
private processing = false
|
||||
|
||||
async add(job: T): Promise<void> {
|
||||
this.queue.push(job)
|
||||
|
||||
if (!this.processing) {
|
||||
this.process()
|
||||
}
|
||||
}
|
||||
|
||||
private async process(): Promise<void> {
|
||||
this.processing = true
|
||||
|
||||
while (this.queue.length > 0) {
|
||||
const job = this.queue.shift()!
|
||||
|
||||
try {
|
||||
await this.execute(job)
|
||||
} catch (error) {
|
||||
console.error('Job failed:', error)
|
||||
}
|
||||
}
|
||||
|
||||
this.processing = false
|
||||
}
|
||||
|
||||
private async execute(job: T): Promise<void> {
|
||||
// Job execution logic
|
||||
}
|
||||
}
|
||||
|
||||
// Usage for indexing markets
|
||||
interface IndexJob {
|
||||
marketId: string
|
||||
}
|
||||
|
||||
const indexQueue = new JobQueue<IndexJob>()
|
||||
|
||||
export async function POST(request: Request) {
|
||||
const { marketId } = await request.json()
|
||||
|
||||
// Add to queue instead of blocking
|
||||
await indexQueue.add({ marketId })
|
||||
|
||||
return NextResponse.json({ success: true, message: 'Job queued' })
|
||||
}
|
||||
```
|
||||
|
||||
## Logging & Monitoring
|
||||
|
||||
### Structured Logging
|
||||
|
||||
```typescript
|
||||
interface LogContext {
|
||||
userId?: string
|
||||
requestId?: string
|
||||
method?: string
|
||||
path?: string
|
||||
[key: string]: unknown
|
||||
}
|
||||
|
||||
class Logger {
|
||||
log(level: 'info' | 'warn' | 'error', message: string, context?: LogContext) {
|
||||
const entry = {
|
||||
timestamp: new Date().toISOString(),
|
||||
level,
|
||||
message,
|
||||
...context
|
||||
}
|
||||
|
||||
console.log(JSON.stringify(entry))
|
||||
}
|
||||
|
||||
info(message: string, context?: LogContext) {
|
||||
this.log('info', message, context)
|
||||
}
|
||||
|
||||
warn(message: string, context?: LogContext) {
|
||||
this.log('warn', message, context)
|
||||
}
|
||||
|
||||
error(message: string, error: Error, context?: LogContext) {
|
||||
this.log('error', message, {
|
||||
...context,
|
||||
error: error.message,
|
||||
stack: error.stack
|
||||
})
|
||||
}
|
||||
}
|
||||
|
||||
const logger = new Logger()
|
||||
|
||||
// Usage
|
||||
export async function GET(request: Request) {
|
||||
const requestId = crypto.randomUUID()
|
||||
|
||||
logger.info('Fetching markets', {
|
||||
requestId,
|
||||
method: 'GET',
|
||||
path: '/api/markets'
|
||||
})
|
||||
|
||||
try {
|
||||
const markets = await fetchMarkets()
|
||||
return NextResponse.json({ success: true, data: markets })
|
||||
} catch (error) {
|
||||
logger.error('Failed to fetch markets', error as Error, { requestId })
|
||||
return NextResponse.json({ error: 'Internal error' }, { status: 500 })
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Remember**: Backend patterns enable scalable, maintainable server-side applications. Choose patterns that fit your complexity level.

# ClickHouse Analytics Patterns
|
||||
|
||||
ClickHouse-specific patterns for high-performance analytics and data engineering.
|
||||
|
||||
## Overview
|
||||
|
||||
ClickHouse is a column-oriented database management system (DBMS) for online analytical processing (OLAP). It's optimized for fast analytical queries on large datasets.
|
||||
|
||||
**Key Features:**
|
||||
- Column-oriented storage
|
||||
- Data compression
|
||||
- Parallel query execution
|
||||
- Distributed queries
|
||||
- Real-time analytics
|
||||
|
||||
## Table Design Patterns
|
||||
|
||||
### MergeTree Engine (Most Common)
|
||||
|
||||
```sql
|
||||
CREATE TABLE markets_analytics (
|
||||
date Date,
|
||||
market_id String,
|
||||
market_name String,
|
||||
volume UInt64,
|
||||
trades UInt32,
|
||||
unique_traders UInt32,
|
||||
avg_trade_size Float64,
|
||||
created_at DateTime
|
||||
) ENGINE = MergeTree()
|
||||
PARTITION BY toYYYYMM(date)
|
||||
ORDER BY (date, market_id)
|
||||
SETTINGS index_granularity = 8192;
|
||||
```
|
||||
|
||||
### ReplacingMergeTree (Deduplication)
|
||||
|
||||
```sql
|
||||
-- For data that may have duplicates (e.g., from multiple sources)
|
||||
CREATE TABLE user_events (
|
||||
event_id String,
|
||||
user_id String,
|
||||
event_type String,
|
||||
timestamp DateTime,
|
||||
properties String
|
||||
) ENGINE = ReplacingMergeTree()
|
||||
PARTITION BY toYYYYMM(timestamp)
|
||||
ORDER BY (user_id, event_id, timestamp)
|
||||
PRIMARY KEY (user_id, event_id);
|
||||
```
|
||||
|
||||
### AggregatingMergeTree (Pre-aggregation)
|
||||
|
||||
```sql
|
||||
-- For maintaining aggregated metrics
|
||||
CREATE TABLE market_stats_hourly (
|
||||
hour DateTime,
|
||||
market_id String,
|
||||
total_volume AggregateFunction(sum, UInt64),
|
||||
total_trades AggregateFunction(count, UInt32),
|
||||
unique_users AggregateFunction(uniq, String)
|
||||
) ENGINE = AggregatingMergeTree()
|
||||
PARTITION BY toYYYYMM(hour)
|
||||
ORDER BY (hour, market_id);
|
||||
|
||||
-- Query aggregated data
|
||||
SELECT
|
||||
hour,
|
||||
market_id,
|
||||
sumMerge(total_volume) AS volume,
|
||||
countMerge(total_trades) AS trades,
|
||||
uniqMerge(unique_users) AS users
|
||||
FROM market_stats_hourly
|
||||
WHERE hour >= toStartOfHour(now() - INTERVAL 24 HOUR)
|
||||
GROUP BY hour, market_id
|
||||
ORDER BY hour DESC;
|
||||
```
|
||||
|
||||
## Query Optimization Patterns
|
||||
|
||||
### Efficient Filtering
|
||||
|
||||
```sql
|
||||
-- ✅ GOOD: Use indexed columns first
|
||||
SELECT *
|
||||
FROM markets_analytics
|
||||
WHERE date >= '2025-01-01'
|
||||
AND market_id = 'market-123'
|
||||
AND volume > 1000
|
||||
ORDER BY date DESC
|
||||
LIMIT 100;
|
||||
|
||||
-- ❌ BAD: Filter on non-indexed columns first
|
||||
SELECT *
|
||||
FROM markets_analytics
|
||||
WHERE volume > 1000
|
||||
AND market_name LIKE '%election%'
|
||||
AND date >= '2025-01-01';
|
||||
```
|
||||
|
||||
### Aggregations
|
||||
|
||||
```sql
|
||||
-- ✅ GOOD: Use ClickHouse-specific aggregation functions
|
||||
SELECT
|
||||
toStartOfDay(created_at) AS day,
|
||||
market_id,
|
||||
sum(volume) AS total_volume,
|
||||
count() AS total_trades,
|
||||
uniq(trader_id) AS unique_traders,
|
||||
avg(trade_size) AS avg_size
|
||||
FROM trades
|
||||
WHERE created_at >= today() - INTERVAL 7 DAY
|
||||
GROUP BY day, market_id
|
||||
ORDER BY day DESC, total_volume DESC;
|
||||
|
||||
-- ✅ Use quantile for percentiles (more efficient than percentile)
|
||||
SELECT
|
||||
quantile(0.50)(trade_size) AS median,
|
||||
quantile(0.95)(trade_size) AS p95,
|
||||
quantile(0.99)(trade_size) AS p99
|
||||
FROM trades
|
||||
WHERE created_at >= now() - INTERVAL 1 HOUR;
|
||||
```
|
||||
|
||||
### Window Functions
|
||||
|
||||
```sql
|
||||
-- Calculate running totals
|
||||
SELECT
|
||||
date,
|
||||
market_id,
|
||||
volume,
|
||||
sum(volume) OVER (
|
||||
PARTITION BY market_id
|
||||
ORDER BY date
|
||||
ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
|
||||
) AS cumulative_volume
|
||||
FROM markets_analytics
|
||||
WHERE date >= today() - INTERVAL 30 DAY
|
||||
ORDER BY market_id, date;
|
||||
```
|
||||
|
||||
## Data Insertion Patterns
|
||||
|
||||
### Bulk Insert (Recommended)
|
||||
|
||||
```typescript
|
||||
import { ClickHouse } from 'clickhouse'
|
||||
|
||||
const clickhouse = new ClickHouse({
|
||||
url: process.env.CLICKHOUSE_URL,
|
||||
port: 8123,
|
||||
basicAuth: {
|
||||
username: process.env.CLICKHOUSE_USER,
|
||||
password: process.env.CLICKHOUSE_PASSWORD
|
||||
}
|
||||
})
|
||||
|
||||
// ✅ Batch insert (efficient)
|
||||
async function bulkInsertTrades(trades: Trade[]) {
|
||||
const values = trades.map(trade => `(
|
||||
'${trade.id}',
|
||||
'${trade.market_id}',
|
||||
'${trade.user_id}',
|
||||
${trade.amount},
|
||||
'${trade.timestamp.toISOString()}'
|
||||
)`).join(',')
|
||||
|
||||
await clickhouse.query(`
|
||||
INSERT INTO trades (id, market_id, user_id, amount, timestamp)
|
||||
VALUES ${values}
|
||||
`).toPromise()
|
||||
}
|
||||
|
||||
// ❌ Individual inserts (slow)
|
||||
async function insertTrade(trade: Trade) {
|
||||
// Don't do this in a loop!
|
||||
await clickhouse.query(`
|
||||
INSERT INTO trades VALUES ('${trade.id}', ...)
|
||||
`).toPromise()
|
||||
}
|
||||
```
|
||||
|
||||
### Streaming Insert
|
||||
|
||||
```typescript
|
||||
// For continuous data ingestion
|
||||
import { createWriteStream } from 'fs'
|
||||
import { pipeline } from 'stream/promises'
|
||||
|
||||
async function streamInserts() {
|
||||
const stream = clickhouse.insert('trades').stream()
|
||||
|
||||
for await (const batch of dataSource) {
|
||||
stream.write(batch)
|
||||
}
|
||||
|
||||
await stream.end()
|
||||
}
|
||||
```
|
||||
|
||||
## Materialized Views
|
||||
|
||||
### Real-time Aggregations
|
||||
|
||||
```sql
|
||||
-- Create materialized view for hourly stats
|
||||
CREATE MATERIALIZED VIEW market_stats_hourly_mv
|
||||
TO market_stats_hourly
|
||||
AS SELECT
|
||||
toStartOfHour(timestamp) AS hour,
|
||||
market_id,
|
||||
sumState(amount) AS total_volume,
|
||||
countState() AS total_trades,
|
||||
uniqState(user_id) AS unique_users
|
||||
FROM trades
|
||||
GROUP BY hour, market_id;
|
||||
|
||||
-- Query the materialized view
|
||||
SELECT
|
||||
hour,
|
||||
market_id,
|
||||
sumMerge(total_volume) AS volume,
|
||||
countMerge(total_trades) AS trades,
|
||||
uniqMerge(unique_users) AS users
|
||||
FROM market_stats_hourly
|
||||
WHERE hour >= now() - INTERVAL 24 HOUR
|
||||
GROUP BY hour, market_id;
|
||||
```
|
||||
|
||||
## Performance Monitoring
|
||||
|
||||
### Query Performance
|
||||
|
||||
```sql
|
||||
-- Check slow queries
|
||||
SELECT
|
||||
query_id,
|
||||
user,
|
||||
query,
|
||||
query_duration_ms,
|
||||
read_rows,
|
||||
read_bytes,
|
||||
memory_usage
|
||||
FROM system.query_log
|
||||
WHERE type = 'QueryFinish'
|
||||
AND query_duration_ms > 1000
|
||||
AND event_time >= now() - INTERVAL 1 HOUR
|
||||
ORDER BY query_duration_ms DESC
|
||||
LIMIT 10;
|
||||
```
|
||||
|
||||
### Table Statistics
|
||||
|
||||
```sql
|
||||
-- Check table sizes
|
||||
SELECT
|
||||
database,
|
||||
table,
|
||||
formatReadableSize(sum(bytes)) AS size,
|
||||
sum(rows) AS rows,
|
||||
max(modification_time) AS latest_modification
|
||||
FROM system.parts
|
||||
WHERE active
|
||||
GROUP BY database, table
|
||||
ORDER BY sum(bytes) DESC;
|
||||
```
|
||||
|
||||
## Common Analytics Queries
|
||||
|
||||
### Time Series Analysis
|
||||
|
||||
```sql
|
||||
-- Daily active users
|
||||
SELECT
|
||||
toDate(timestamp) AS date,
|
||||
uniq(user_id) AS daily_active_users
|
||||
FROM events
|
||||
WHERE timestamp >= today() - INTERVAL 30 DAY
|
||||
GROUP BY date
|
||||
ORDER BY date;
|
||||
|
||||
-- Retention analysis
|
||||
SELECT
|
||||
signup_date,
|
||||
countIf(days_since_signup = 0) AS day_0,
|
||||
countIf(days_since_signup = 1) AS day_1,
|
||||
countIf(days_since_signup = 7) AS day_7,
|
||||
countIf(days_since_signup = 30) AS day_30
|
||||
FROM (
|
||||
SELECT
|
||||
user_id,
|
||||
min(toDate(timestamp)) AS signup_date,
|
||||
toDate(timestamp) AS activity_date,
|
||||
dateDiff('day', signup_date, activity_date) AS days_since_signup
|
||||
FROM events
|
||||
GROUP BY user_id, activity_date
|
||||
)
|
||||
GROUP BY signup_date
|
||||
ORDER BY signup_date DESC;
|
||||
```
|
||||
|
||||
### Funnel Analysis
|
||||
|
||||
```sql
|
||||
-- Conversion funnel
|
||||
SELECT
|
||||
countIf(step = 'viewed_market') AS viewed,
|
||||
countIf(step = 'clicked_trade') AS clicked,
|
||||
countIf(step = 'completed_trade') AS completed,
|
||||
round(clicked / viewed * 100, 2) AS view_to_click_rate,
|
||||
round(completed / clicked * 100, 2) AS click_to_completion_rate
|
||||
FROM (
|
||||
SELECT
|
||||
user_id,
|
||||
session_id,
|
||||
event_type AS step
|
||||
FROM events
|
||||
WHERE event_date = today()
|
||||
)
|
||||
GROUP BY session_id;
|
||||
```
|
||||
|
||||
### Cohort Analysis
|
||||
|
||||
```sql
|
||||
-- User cohorts by signup month
|
||||
SELECT
|
||||
toStartOfMonth(signup_date) AS cohort,
|
||||
toStartOfMonth(activity_date) AS month,
|
||||
dateDiff('month', cohort, month) AS months_since_signup,
|
||||
count(DISTINCT user_id) AS active_users
|
||||
FROM (
|
||||
SELECT
|
||||
user_id,
|
||||
min(toDate(timestamp)) OVER (PARTITION BY user_id) AS signup_date,
|
||||
toDate(timestamp) AS activity_date
|
||||
FROM events
|
||||
)
|
||||
GROUP BY cohort, month, months_since_signup
|
||||
ORDER BY cohort, months_since_signup;
|
||||
```
|
||||
|
||||
## Data Pipeline Patterns
|
||||
|
||||
### ETL Pattern
|
||||
|
||||
```typescript
|
||||
// Extract, Transform, Load
|
||||
async function etlPipeline() {
|
||||
// 1. Extract from source
|
||||
const rawData = await extractFromPostgres()
|
||||
|
||||
// 2. Transform
|
||||
const transformed = rawData.map(row => ({
|
||||
date: new Date(row.created_at).toISOString().split('T')[0],
|
||||
market_id: row.market_slug,
|
||||
volume: parseFloat(row.total_volume),
|
||||
trades: parseInt(row.trade_count)
|
||||
}))
|
||||
|
||||
// 3. Load to ClickHouse
|
||||
await bulkInsertToClickHouse(transformed)
|
||||
}
|
||||
|
||||
// Run periodically
|
||||
setInterval(etlPipeline, 60 * 60 * 1000) // Every hour
|
||||
```
|
||||
|
||||
### Change Data Capture (CDC)
|
||||
|
||||
```typescript
|
||||
// Listen to PostgreSQL changes and sync to ClickHouse
|
||||
import { Client } from 'pg'
|
||||
|
||||
const pgClient = new Client({ connectionString: process.env.DATABASE_URL })
|
||||
|
||||
pgClient.query('LISTEN market_updates')
|
||||
|
||||
pgClient.on('notification', async (msg) => {
|
||||
const update = JSON.parse(msg.payload)
|
||||
|
||||
await clickhouse.insert('market_updates', [
|
||||
{
|
||||
market_id: update.id,
|
||||
event_type: update.operation, // INSERT, UPDATE, DELETE
|
||||
timestamp: new Date(),
|
||||
data: JSON.stringify(update.new_data)
|
||||
}
|
||||
])
|
||||
})
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Partitioning Strategy
|
||||
- Partition by time (usually month or day)
|
||||
- Avoid too many partitions (performance impact)
|
||||
- Use DATE type for partition key
|
||||
|
||||
### 2. Ordering Key
|
||||
- Put most frequently filtered columns first
|
||||
- Consider cardinality (high cardinality first)
|
||||
- Order impacts compression
|
||||
|
||||
### 3. Data Types
|
||||
- Use smallest appropriate type (UInt32 vs UInt64)
|
||||
- Use LowCardinality for repeated strings
|
||||
- Use Enum for categorical data
|
||||
|
||||
### 4. Avoid
|
||||
- SELECT * (specify columns)
|
||||
- FINAL (merge data before query instead)
|
||||
- Too many JOINs (denormalize for analytics)
|
||||
- Small frequent inserts (batch instead)
|
||||
|
||||
### 5. Monitoring
|
||||
- Track query performance
|
||||
- Monitor disk usage
|
||||
- Check merge operations
|
||||
- Review slow query log
|
||||
|
||||
**Remember**: ClickHouse excels at analytical workloads. Design tables for your query patterns, batch inserts, and leverage materialized views for real-time aggregations.

# Coding Standards & Best Practices
|
||||
|
||||
Universal coding standards applicable across all projects.
|
||||
|
||||
## Code Quality Principles
|
||||
|
||||
### 1. Readability First
|
||||
- Code is read more than written
|
||||
- Clear variable and function names
|
||||
- Self-documenting code preferred over comments
|
||||
- Consistent formatting
|
||||
|
||||
### 2. KISS (Keep It Simple, Stupid)
|
||||
- Simplest solution that works
|
||||
- Avoid over-engineering
|
||||
- No premature optimization
|
||||
- Easy to understand > clever code
|
||||
|
||||
### 3. DRY (Don't Repeat Yourself)
|
||||
- Extract common logic into functions
|
||||
- Create reusable components
|
||||
- Share utilities across modules
|
||||
- Avoid copy-paste programming
|
||||
|
||||
### 4. YAGNI (You Aren't Gonna Need It)
|
||||
- Don't build features before they're needed
|
||||
- Avoid speculative generality
|
||||
- Add complexity only when required
|
||||
- Start simple, refactor when needed
|
||||
|
||||
## TypeScript/JavaScript Standards
|
||||
|
||||
### Variable Naming
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Descriptive names
|
||||
const marketSearchQuery = 'election'
|
||||
const isUserAuthenticated = true
|
||||
const totalRevenue = 1000
|
||||
|
||||
// ❌ BAD: Unclear names
|
||||
const q = 'election'
|
||||
const flag = true
|
||||
const x = 1000
|
||||
```
|
||||
|
||||
### Function Naming
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Verb-noun pattern
|
||||
async function fetchMarketData(marketId: string) { }
|
||||
function calculateSimilarity(a: number[], b: number[]) { }
|
||||
function isValidEmail(email: string): boolean { }
|
||||
|
||||
// ❌ BAD: Unclear or noun-only
|
||||
async function market(id: string) { }
|
||||
function similarity(a, b) { }
|
||||
function email(e) { }
|
||||
```
|
||||
|
||||
### Immutability Pattern (CRITICAL)
|
||||
|
||||
```typescript
|
||||
// ✅ ALWAYS use spread operator
|
||||
const updatedUser = {
|
||||
...user,
|
||||
name: 'New Name'
|
||||
}
|
||||
|
||||
const updatedArray = [...items, newItem]
|
||||
|
||||
// ❌ NEVER mutate directly
|
||||
user.name = 'New Name' // BAD
|
||||
items.push(newItem) // BAD
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Comprehensive error handling
|
||||
async function fetchData(url: string) {
|
||||
try {
|
||||
const response = await fetch(url)
|
||||
|
||||
if (!response.ok) {
|
||||
throw new Error(`HTTP ${response.status}: ${response.statusText}`)
|
||||
}
|
||||
|
||||
return await response.json()
|
||||
} catch (error) {
|
||||
console.error('Fetch failed:', error)
|
||||
throw new Error('Failed to fetch data')
|
||||
}
|
||||
}
|
||||
|
||||
// ❌ BAD: No error handling
|
||||
async function fetchData(url) {
|
||||
const response = await fetch(url)
|
||||
return response.json()
|
||||
}
|
||||
```
|
||||
|
||||
### Async/Await Best Practices
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Parallel execution when possible
|
||||
const [users, markets, stats] = await Promise.all([
|
||||
fetchUsers(),
|
||||
fetchMarkets(),
|
||||
fetchStats()
|
||||
])
|
||||
|
||||
// ❌ BAD: Sequential when unnecessary
|
||||
const users = await fetchUsers()
|
||||
const markets = await fetchMarkets()
|
||||
const stats = await fetchStats()
|
||||
```
|
||||
|
||||
### Type Safety
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Proper types
|
||||
interface Market {
|
||||
id: string
|
||||
name: string
|
||||
status: 'active' | 'resolved' | 'closed'
|
||||
created_at: Date
|
||||
}
|
||||
|
||||
function getMarket(id: string): Promise<Market> {
|
||||
// Implementation
|
||||
}
|
||||
|
||||
// ❌ BAD: Using 'any'
|
||||
function getMarket(id: any): Promise<any> {
|
||||
// Implementation
|
||||
}
|
||||
```
|
||||
|
||||
## React Best Practices
|
||||
|
||||
### Component Structure
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Functional component with types
|
||||
interface ButtonProps {
|
||||
children: React.ReactNode
|
||||
onClick: () => void
|
||||
disabled?: boolean
|
||||
variant?: 'primary' | 'secondary'
|
||||
}
|
||||
|
||||
export function Button({
|
||||
children,
|
||||
onClick,
|
||||
disabled = false,
|
||||
variant = 'primary'
|
||||
}: ButtonProps) {
|
||||
return (
|
||||
<button
|
||||
onClick={onClick}
|
||||
disabled={disabled}
|
||||
className={`btn btn-${variant}`}
|
||||
>
|
||||
{children}
|
||||
</button>
|
||||
)
|
||||
}
|
||||
|
||||
// ❌ BAD: No types, unclear structure
|
||||
export function Button(props) {
|
||||
return <button onClick={props.onClick}>{props.children}</button>
|
||||
}
|
||||
```
|
||||
|
||||
### Custom Hooks
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Reusable custom hook
|
||||
export function useDebounce<T>(value: T, delay: number): T {
|
||||
const [debouncedValue, setDebouncedValue] = useState<T>(value)
|
||||
|
||||
useEffect(() => {
|
||||
const handler = setTimeout(() => {
|
||||
setDebouncedValue(value)
|
||||
}, delay)
|
||||
|
||||
return () => clearTimeout(handler)
|
||||
}, [value, delay])
|
||||
|
||||
return debouncedValue
|
||||
}
|
||||
|
||||
// Usage
|
||||
const debouncedQuery = useDebounce(searchQuery, 500)
|
||||
```
|
||||
|
||||
### State Management
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Proper state updates
|
||||
const [count, setCount] = useState(0)
|
||||
|
||||
// Functional update for state based on previous state
|
||||
setCount(prev => prev + 1)
|
||||
|
||||
// ❌ BAD: Direct state reference
|
||||
setCount(count + 1) // Can be stale in async scenarios
|
||||
```
|
||||
|
||||
### Conditional Rendering
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Clear conditional rendering
|
||||
{isLoading && <Spinner />}
|
||||
{error && <ErrorMessage error={error} />}
|
||||
{data && <DataDisplay data={data} />}
|
||||
|
||||
// ❌ BAD: Ternary hell
|
||||
{isLoading ? <Spinner /> : error ? <ErrorMessage error={error} /> : data ? <DataDisplay data={data} /> : null}
|
||||
```
|
||||
|
||||
## API Design Standards
|
||||
|
||||
### REST API Conventions
|
||||
|
||||
```
|
||||
GET /api/markets # List all markets
|
||||
GET /api/markets/:id # Get specific market
|
||||
POST /api/markets # Create new market
|
||||
PUT /api/markets/:id # Update market (full)
|
||||
PATCH /api/markets/:id # Update market (partial)
|
||||
DELETE /api/markets/:id # Delete market
|
||||
|
||||
# Query parameters for filtering
|
||||
GET /api/markets?status=active&limit=10&offset=0
|
||||
```
|
||||
|
||||
### Response Format
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Consistent response structure
|
||||
interface ApiResponse<T> {
|
||||
success: boolean
|
||||
data?: T
|
||||
error?: string
|
||||
meta?: {
|
||||
total: number
|
||||
page: number
|
||||
limit: number
|
||||
}
|
||||
}
|
||||
|
||||
// Success response
|
||||
return NextResponse.json({
|
||||
success: true,
|
||||
data: markets,
|
||||
meta: { total: 100, page: 1, limit: 10 }
|
||||
})
|
||||
|
||||
// Error response
|
||||
return NextResponse.json({
|
||||
success: false,
|
||||
error: 'Invalid request'
|
||||
}, { status: 400 })
|
||||
```
|
||||
|
||||
### Input Validation
|
||||
|
||||
```typescript
|
||||
import { z } from 'zod'
|
||||
|
||||
// ✅ GOOD: Schema validation
|
||||
const CreateMarketSchema = z.object({
|
||||
name: z.string().min(1).max(200),
|
||||
description: z.string().min(1).max(2000),
|
||||
endDate: z.string().datetime(),
|
||||
categories: z.array(z.string()).min(1)
|
||||
})
|
||||
|
||||
export async function POST(request: Request) {
|
||||
const body = await request.json()
|
||||
|
||||
try {
|
||||
const validated = CreateMarketSchema.parse(body)
|
||||
// Proceed with validated data
|
||||
} catch (error) {
|
||||
if (error instanceof z.ZodError) {
|
||||
return NextResponse.json({
|
||||
success: false,
|
||||
error: 'Validation failed',
|
||||
details: error.errors
|
||||
}, { status: 400 })
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## File Organization
|
||||
|
||||

```
|
||||
|
||||
## Comments & Documentation
|
||||
|
||||
### When to Comment
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Explain WHY, not WHAT
|
||||
// Use exponential backoff to avoid overwhelming the API during outages
|
||||
const delay = Math.min(1000 * Math.pow(2, retryCount), 30000)
|
||||
|
||||
// Deliberately using mutation here for performance with large arrays
|
||||
items.push(newItem)
|
||||
|
||||
// ❌ BAD: Stating the obvious
|
||||
// Increment counter by 1
|
||||
count++
|
||||
|
||||
// Set name to user's name
|
||||
name = user.name
|
||||
```
|
||||
|
||||
### JSDoc for Public APIs
|
||||
|
||||
```typescript
|
||||
/**
|
||||
* Searches markets using semantic similarity.
|
||||
*
|
||||
* @param query - Natural language search query
|
||||
* @param limit - Maximum number of results (default: 10)
|
||||
* @returns Array of markets sorted by similarity score
|
||||
* @throws {Error} If OpenAI API fails or Redis unavailable
|
||||
*
|
||||
* @example
|
||||
* ```typescript
|
||||
* const results = await searchMarkets('election', 5)
|
||||
* console.log(results[0].name) // "Trump vs Biden"
|
||||
* ```
|
||||
*/
|
||||
export async function searchMarkets(
|
||||
query: string,
|
||||
limit: number = 10
|
||||
): Promise<Market[]> {
|
||||
// Implementation
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Best Practices
|
||||
|
||||
### Memoization
|
||||
|
||||
```typescript
|
||||
import { useMemo, useCallback } from 'react'
|
||||
|
||||
// ✅ GOOD: Memoize expensive computations
|
||||
const sortedMarkets = useMemo(() => {
|
||||
return markets.sort((a, b) => b.volume - a.volume)
|
||||
}, [markets])
|
||||
|
||||
// ✅ GOOD: Memoize callbacks
|
||||
const handleSearch = useCallback((query: string) => {
|
||||
setSearchQuery(query)
|
||||
}, [])
|
||||
```
|
||||
|
||||
### Lazy Loading
|
||||
|
||||
```typescript
|
||||
import { lazy, Suspense } from 'react'
|
||||
|
||||
// ✅ GOOD: Lazy load heavy components
|
||||
const HeavyChart = lazy(() => import('./HeavyChart'))
|
||||
|
||||
export function Dashboard() {
|
||||
return (
|
||||
<Suspense fallback={<Spinner />}>
|
||||
<HeavyChart />
|
||||
</Suspense>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
### Database Queries
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Select only needed columns
|
||||
const { data } = await supabase
|
||||
.from('markets')
|
||||
.select('id, name, status')
|
||||
.limit(10)
|
||||
|
||||
// ❌ BAD: Select everything
|
||||
const { data } = await supabase
|
||||
.from('markets')
|
||||
.select('*')
|
||||
```
|
||||
|
||||
## Testing Standards
|
||||
|
||||
### Test Structure (AAA Pattern)
|
||||
|
||||
```typescript
|
||||
test('calculates similarity correctly', () => {
|
||||
// Arrange
|
||||
const vector1 = [1, 0, 0]
|
||||
const vector2 = [0, 1, 0]
|
||||
|
||||
// Act
|
||||
const similarity = calculateCosineSimilarity(vector1, vector2)
|
||||
|
||||
// Assert
|
||||
expect(similarity).toBe(0)
|
||||
})
|
||||
```
|
||||
|
||||
### Test Naming
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Descriptive test names
|
||||
test('returns empty array when no markets match query', () => { })
|
||||
test('throws error when OpenAI API key is missing', () => { })
|
||||
test('falls back to substring search when Redis unavailable', () => { })
|
||||
|
||||
// ❌ BAD: Vague test names
|
||||
test('works', () => { })
|
||||
test('test search', () => { })
|
||||
```
|
||||
|
||||
## Code Smell Detection
|
||||
|
||||
Watch for these anti-patterns:
|
||||
|
||||
### 1. Long Functions
|
||||
```typescript
|
||||
// ❌ BAD: Function > 50 lines
|
||||
function processMarketData() {
|
||||
// 100 lines of code
|
||||
}
|
||||
|
||||
// ✅ GOOD: Split into smaller functions
|
||||
function processMarketData() {
|
||||
const validated = validateData()
|
||||
const transformed = transformData(validated)
|
||||
return saveData(transformed)
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Deep Nesting
|
||||
```typescript
|
||||
// ❌ BAD: 5+ levels of nesting
|
||||
if (user) {
|
||||
if (user.isAdmin) {
|
||||
if (market) {
|
||||
if (market.isActive) {
|
||||
if (hasPermission) {
|
||||
// Do something
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
// ✅ GOOD: Early returns
|
||||
if (!user) return
|
||||
if (!user.isAdmin) return
|
||||
if (!market) return
|
||||
if (!market.isActive) return
|
||||
if (!hasPermission) return
|
||||
|
||||
// Do something
|
||||
```
|
||||
|
||||
### 3. Magic Numbers
|
||||
```typescript
|
||||
// ❌ BAD: Unexplained numbers
|
||||
if (retryCount > 3) { }
|
||||
setTimeout(callback, 500)
|
||||
|
||||
// ✅ GOOD: Named constants
|
||||
const MAX_RETRIES = 3
|
||||
const DEBOUNCE_DELAY_MS = 500
|
||||
|
||||
if (retryCount > MAX_RETRIES) { }
|
||||
setTimeout(callback, DEBOUNCE_DELAY_MS)
|
||||
```
|
||||
|
||||
**Remember**: Code quality is not negotiable. Clear, maintainable code enables rapid development and confident refactoring.

# Frontend Development Patterns
|
||||
|
||||
Modern frontend patterns for React, Next.js, and performant user interfaces.
|
||||
|
||||
## Component Patterns
|
||||
|
||||
### Composition Over Inheritance
|
||||
|
||||
```typescript
|
||||
// ✅ GOOD: Component composition
|
||||
interface CardProps {
|
||||
children: React.ReactNode
|
||||
variant?: 'default' | 'outlined'
|
||||
}
|
||||
|
||||
export function Card({ children, variant = 'default' }: CardProps) {
|
||||
return <div className={`card card-${variant}`}>{children}</div>
|
||||
}
|
||||
|
||||
export function CardHeader({ children }: { children: React.ReactNode }) {
|
||||
return <div className="card-header">{children}</div>
|
||||
}
|
||||
|
||||
export function CardBody({ children }: { children: React.ReactNode }) {
|
||||
return <div className="card-body">{children}</div>
|
||||
}
|
||||
|
||||
// Usage
|
||||
<Card>
|
||||
<CardHeader>Title</CardHeader>
|
||||
<CardBody>Content</CardBody>
|
||||
</Card>
|
||||
```
|
||||
|
||||
### Compound Components
|
||||
|
||||
```typescript
|
||||
interface TabsContextValue {
|
||||
activeTab: string
|
||||
setActiveTab: (tab: string) => void
|
||||
}
|
||||
|
||||
const TabsContext = createContext<TabsContextValue | undefined>(undefined)
|
||||
|
||||
export function Tabs({ children, defaultTab }: {
|
||||
children: React.ReactNode
|
||||
defaultTab: string
|
||||
}) {
|
||||
const [activeTab, setActiveTab] = useState(defaultTab)
|
||||
|
||||
return (
|
||||
<TabsContext.Provider value={{ activeTab, setActiveTab }}>
|
||||
{children}
|
||||
</TabsContext.Provider>
|
||||
)
|
||||
}
|
||||
|
||||
export function TabList({ children }: { children: React.ReactNode }) {
|
||||
return <div className="tab-list">{children}</div>
|
||||
}
|
||||
|
||||
export function Tab({ id, children }: { id: string, children: React.ReactNode }) {
|
||||
const context = useContext(TabsContext)
|
||||
if (!context) throw new Error('Tab must be used within Tabs')
|
||||
|
||||
return (
|
||||
<button
|
||||
className={context.activeTab === id ? 'active' : ''}
|
||||
onClick={() => context.setActiveTab(id)}
|
||||
>
|
||||
{children}
|
||||
</button>
|
||||
)
|
||||
}
|
||||
|
||||
// Usage
|
||||
<Tabs defaultTab="overview">
|
||||
<TabList>
|
||||
<Tab id="overview">Overview</Tab>
|
||||
<Tab id="details">Details</Tab>
|
||||
</TabList>
|
||||
</Tabs>
|
||||
```
|
||||
|
||||
### Render Props Pattern
|
||||
|
||||
```typescript
|
||||
interface DataLoaderProps<T> {
|
||||
url: string
|
||||
children: (data: T | null, loading: boolean, error: Error | null) => React.ReactNode
|
||||
}
|
||||
|
||||
export function DataLoader<T>({ url, children }: DataLoaderProps<T>) {
|
||||
const [data, setData] = useState<T | null>(null)
|
||||
const [loading, setLoading] = useState(true)
|
||||
const [error, setError] = useState<Error | null>(null)
|
||||
|
||||
useEffect(() => {
|
||||
fetch(url)
|
||||
.then(res => res.json())
|
||||
.then(setData)
|
||||
.catch(setError)
|
||||
.finally(() => setLoading(false))
|
||||
}, [url])
|
||||
|
||||
return <>{children(data, loading, error)}</>
|
||||
}
|
||||
|
||||
// Usage
|
||||
<DataLoader<Market[]> url="/api/markets">
|
||||
{(markets, loading, error) => {
|
||||
if (loading) return <Spinner />
|
||||
if (error) return <Error error={error} />
|
||||
return <MarketList markets={markets!} />
|
||||
}}
|
||||
</DataLoader>
|
||||
```
|
||||
|
||||
## Custom Hooks Patterns
|
||||
|
||||
### State Management Hook
|
||||
|
||||
```typescript
|
||||
export function useToggle(initialValue = false): [boolean, () => void] {
|
||||
const [value, setValue] = useState(initialValue)
|
||||
|
||||
const toggle = useCallback(() => {
|
||||
setValue(v => !v)
|
||||
}, [])
|
||||
|
||||
return [value, toggle]
|
||||
}
|
||||
|
||||
// Usage
|
||||
const [isOpen, toggleOpen] = useToggle()
|
||||
```
|
||||
|
||||
### Async Data Fetching Hook
|
||||
|
||||
```typescript
|
||||
interface UseQueryOptions<T> {
|
||||
onSuccess?: (data: T) => void
|
||||
onError?: (error: Error) => void
|
||||
enabled?: boolean
|
||||
}
|
||||
|
||||
export function useQuery<T>(
|
||||
key: string,
|
||||
fetcher: () => Promise<T>,
|
||||
options?: UseQueryOptions<T>
|
||||
) {
|
||||
const [data, setData] = useState<T | null>(null)
|
||||
const [error, setError] = useState<Error | null>(null)
|
||||
const [loading, setLoading] = useState(false)
|
||||
|
||||
const refetch = useCallback(async () => {
|
||||
setLoading(true)
|
||||
setError(null)
|
||||
|
||||
try {
|
||||
const result = await fetcher()
|
||||
setData(result)
|
||||
options?.onSuccess?.(result)
|
||||
} catch (err) {
|
||||
const error = err as Error
|
||||
setError(error)
|
||||
options?.onError?.(error)
|
||||
} finally {
|
||||
setLoading(false)
|
||||
}
|
||||
}, [fetcher, options])
|
||||
|
||||
useEffect(() => {
|
||||
if (options?.enabled !== false) {
|
||||
refetch()
|
||||
}
|
||||
}, [key, refetch, options?.enabled])
|
||||
|
||||
return { data, error, loading, refetch }
|
||||
}
|
||||
|
||||
// Usage
|
||||
const { data: markets, loading, error, refetch } = useQuery(
|
||||
'markets',
|
||||
() => fetch('/api/markets').then(r => r.json()),
|
||||
{
|
||||
onSuccess: data => console.log('Fetched', data.length, 'markets'),
|
||||
onError: err => console.error('Failed:', err)
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### Debounce Hook
|
||||
|
||||
```typescript
|
||||
export function useDebounce<T>(value: T, delay: number): T {
|
||||
const [debouncedValue, setDebouncedValue] = useState<T>(value)
|
||||
|
||||
useEffect(() => {
|
||||
const handler = setTimeout(() => {
|
||||
setDebouncedValue(value)
|
||||
}, delay)
|
||||
|
||||
return () => clearTimeout(handler)
|
||||
}, [value, delay])
|
||||
|
||||
return debouncedValue
|
||||
}
|
||||
|
||||
// Usage
|
||||
const [searchQuery, setSearchQuery] = useState('')
|
||||
const debouncedQuery = useDebounce(searchQuery, 500)
|
||||
|
||||
useEffect(() => {
|
||||
if (debouncedQuery) {
|
||||
performSearch(debouncedQuery)
|
||||
}
|
||||
}, [debouncedQuery])
|
||||
```
|
||||
|
||||
## State Management Patterns
|
||||
|
||||
### Context + Reducer Pattern
|
||||
|
||||
```typescript
|
||||
interface State {
|
||||
markets: Market[]
|
||||
selectedMarket: Market | null
|
||||
loading: boolean
|
||||
}
|
||||
|
||||
type Action =
|
||||
| { type: 'SET_MARKETS'; payload: Market[] }
|
||||
| { type: 'SELECT_MARKET'; payload: Market }
|
||||
| { type: 'SET_LOADING'; payload: boolean }
|
||||
|
||||
function reducer(state: State, action: Action): State {
|
||||
switch (action.type) {
|
||||
case 'SET_MARKETS':
|
||||
return { ...state, markets: action.payload }
|
||||
case 'SELECT_MARKET':
|
||||
return { ...state, selectedMarket: action.payload }
|
||||
case 'SET_LOADING':
|
||||
return { ...state, loading: action.payload }
|
||||
default:
|
||||
return state
|
||||
}
|
||||
}
|
||||
|
||||
const MarketContext = createContext<{
|
||||
state: State
|
||||
dispatch: Dispatch<Action>
|
||||
} | undefined>(undefined)
|
||||
|
||||
export function MarketProvider({ children }: { children: React.ReactNode }) {
|
||||
const [state, dispatch] = useReducer(reducer, {
|
||||
markets: [],
|
||||
selectedMarket: null,
|
||||
loading: false
|
||||
})
|
||||
|
||||
return (
|
||||
<MarketContext.Provider value={{ state, dispatch }}>
|
||||
{children}
|
||||
</MarketContext.Provider>
|
||||
)
|
||||
}
|
||||
|
||||
export function useMarkets() {
|
||||
const context = useContext(MarketContext)
|
||||
if (!context) throw new Error('useMarkets must be used within MarketProvider')
|
||||
return context
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Memoization
|
||||
|
||||
```typescript
|
||||
// ✅ useMemo for expensive computations
|
||||
const sortedMarkets = useMemo(() => {
|
||||
return markets.sort((a, b) => b.volume - a.volume)
|
||||
}, [markets])
|
||||
|
||||
// ✅ useCallback for functions passed to children
|
||||
const handleSearch = useCallback((query: string) => {
|
||||
setSearchQuery(query)
|
||||
}, [])
|
||||
|
||||
// ✅ React.memo for pure components
|
||||
export const MarketCard = React.memo<MarketCardProps>(({ market }) => {
|
||||
return (
|
||||
<div className="market-card">
|
||||
<h3>{market.name}</h3>
|
||||
<p>{market.description}</p>
|
||||
</div>
|
||||
)
|
||||
})
|
||||
```
|
||||
|
||||
### Code Splitting & Lazy Loading
|
||||
|
||||
```typescript
|
||||
import { lazy, Suspense } from 'react'
|
||||
|
||||
// ✅ Lazy load heavy components
|
||||
const HeavyChart = lazy(() => import('./HeavyChart'))
|
||||
const ThreeJsBackground = lazy(() => import('./ThreeJsBackground'))
|
||||
|
||||
export function Dashboard() {
|
||||
return (
|
||||
<div>
|
||||
<Suspense fallback={<ChartSkeleton />}>
|
||||
<HeavyChart data={data} />
|
||||
</Suspense>
|
||||
|
||||
<Suspense fallback={null}>
|
||||
<ThreeJsBackground />
|
||||
</Suspense>
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
### Virtualization for Long Lists
|
||||
|
||||
```typescript
|
||||
import { useVirtualizer } from '@tanstack/react-virtual'
|
||||
|
||||
export function VirtualMarketList({ markets }: { markets: Market[] }) {
|
||||
const parentRef = useRef<HTMLDivElement>(null)
|
||||
|
||||
const virtualizer = useVirtualizer({
|
||||
count: markets.length,
|
||||
getScrollElement: () => parentRef.current,
|
||||
estimateSize: () => 100, // Estimated row height
|
||||
overscan: 5 // Extra items to render
|
||||
})
|
||||
|
||||
return (
|
||||
<div ref={parentRef} style={{ height: '600px', overflow: 'auto' }}>
|
||||
<div
|
||||
style={{
|
||||
height: `${virtualizer.getTotalSize()}px`,
|
||||
position: 'relative'
|
||||
}}
|
||||
>
|
||||
{virtualizer.getVirtualItems().map(virtualRow => (
|
||||
<div
|
||||
key={virtualRow.index}
|
||||
style={{
|
||||
position: 'absolute',
|
||||
top: 0,
|
||||
left: 0,
|
||||
width: '100%',
|
||||
height: `${virtualRow.size}px`,
|
||||
transform: `translateY(${virtualRow.start}px)`
|
||||
}}
|
||||
>
|
||||
<MarketCard market={markets[virtualRow.index]} />
|
||||
</div>
|
||||
))}
|
||||
</div>
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
## Form Handling Patterns
|
||||
|
||||
### Controlled Form with Validation
|
||||
|
||||
```typescript
|
||||
interface FormData {
|
||||
name: string
|
||||
description: string
|
||||
endDate: string
|
||||
}
|
||||
|
||||
interface FormErrors {
|
||||
name?: string
|
||||
description?: string
|
||||
endDate?: string
|
||||
}
|
||||
|
||||
export function CreateMarketForm() {
|
||||
const [formData, setFormData] = useState<FormData>({
|
||||
name: '',
|
||||
description: '',
|
||||
endDate: ''
|
||||
})
|
||||
|
||||
const [errors, setErrors] = useState<FormErrors>({})
|
||||
|
||||
const validate = (): boolean => {
|
||||
const newErrors: FormErrors = {}
|
||||
|
||||
if (!formData.name.trim()) {
|
||||
newErrors.name = 'Name is required'
|
||||
} else if (formData.name.length > 200) {
|
||||
newErrors.name = 'Name must be under 200 characters'
|
||||
}
|
||||
|
||||
if (!formData.description.trim()) {
|
||||
newErrors.description = 'Description is required'
|
||||
}
|
||||
|
||||
if (!formData.endDate) {
|
||||
newErrors.endDate = 'End date is required'
|
||||
}
|
||||
|
||||
setErrors(newErrors)
|
||||
return Object.keys(newErrors).length === 0
|
||||
}
|
||||
|
||||
const handleSubmit = async (e: React.FormEvent) => {
|
||||
e.preventDefault()
|
||||
|
||||
if (!validate()) return
|
||||
|
||||
try {
|
||||
await createMarket(formData)
|
||||
// Success handling
|
||||
} catch (error) {
|
||||
// Error handling
|
||||
}
|
||||
}
|
||||
|
||||
return (
|
||||
<form onSubmit={handleSubmit}>
|
||||
<input
|
||||
value={formData.name}
|
||||
onChange={e => setFormData(prev => ({ ...prev, name: e.target.value }))}
|
||||
placeholder="Market name"
|
||||
/>
|
||||
{errors.name && <span className="error">{errors.name}</span>}
|
||||
|
||||
{/* Other fields */}
|
||||
|
||||
<button type="submit">Create Market</button>
|
||||
</form>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
## Error Boundary Pattern
|
||||
|
||||
```typescript
|
||||
interface ErrorBoundaryState {
|
||||
hasError: boolean
|
||||
error: Error | null
|
||||
}
|
||||
|
||||
export class ErrorBoundary extends React.Component<
|
||||
{ children: React.ReactNode },
|
||||
ErrorBoundaryState
|
||||
> {
|
||||
state: ErrorBoundaryState = {
|
||||
hasError: false,
|
||||
error: null
|
||||
}
|
||||
|
||||
static getDerivedStateFromError(error: Error): ErrorBoundaryState {
|
||||
return { hasError: true, error }
|
||||
}
|
||||
|
||||
componentDidCatch(error: Error, errorInfo: React.ErrorInfo) {
|
||||
console.error('Error boundary caught:', error, errorInfo)
|
||||
}
|
||||
|
||||
render() {
|
||||
if (this.state.hasError) {
|
||||
return (
|
||||
<div className="error-fallback">
|
||||
<h2>Something went wrong</h2>
|
||||
<p>{this.state.error?.message}</p>
|
||||
<button onClick={() => this.setState({ hasError: false })}>
|
||||
Try again
|
||||
</button>
|
||||
</div>
|
||||
)
|
||||
}
|
||||
|
||||
return this.props.children
|
||||
}
|
||||
}
|
||||
|
||||
// Usage
|
||||
<ErrorBoundary>
|
||||
<App />
|
||||
</ErrorBoundary>
|
||||
```
|
||||
|
||||
## Animation Patterns
|
||||
|
||||
### Framer Motion Animations
|
||||
|
||||
```typescript
|
||||
import { motion, AnimatePresence } from 'framer-motion'
|
||||
|
||||
// ✅ List animations
|
||||
export function AnimatedMarketList({ markets }: { markets: Market[] }) {
|
||||
return (
|
||||
<AnimatePresence>
|
||||
{markets.map(market => (
|
||||
<motion.div
|
||||
key={market.id}
|
||||
initial={{ opacity: 0, y: 20 }}
|
||||
animate={{ opacity: 1, y: 0 }}
|
||||
exit={{ opacity: 0, y: -20 }}
|
||||
transition={{ duration: 0.3 }}
|
||||
>
|
||||
<MarketCard market={market} />
|
||||
</motion.div>
|
||||
))}
|
||||
</AnimatePresence>
|
||||
)
|
||||
}
|
||||
|
||||
// ✅ Modal animations
|
||||
export function Modal({ isOpen, onClose, children }: ModalProps) {
|
||||
return (
|
||||
<AnimatePresence>
|
||||
{isOpen && (
|
||||
<>
|
||||
<motion.div
|
||||
className="modal-overlay"
|
||||
initial={{ opacity: 0 }}
|
||||
animate={{ opacity: 1 }}
|
||||
exit={{ opacity: 0 }}
|
||||
onClick={onClose}
|
||||
/>
|
||||
<motion.div
|
||||
className="modal-content"
|
||||
initial={{ opacity: 0, scale: 0.9, y: 20 }}
|
||||
animate={{ opacity: 1, scale: 1, y: 0 }}
|
||||
exit={{ opacity: 0, scale: 0.9, y: 20 }}
|
||||
>
|
||||
{children}
|
||||
</motion.div>
|
||||
</>
|
||||
)}
|
||||
</AnimatePresence>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
## Accessibility Patterns
|
||||
|
||||
### Keyboard Navigation
|
||||
|
||||
```typescript
|
||||
export function Dropdown({ options, onSelect }: DropdownProps) {
|
||||
const [isOpen, setIsOpen] = useState(false)
|
||||
const [activeIndex, setActiveIndex] = useState(0)
|
||||
|
||||
const handleKeyDown = (e: React.KeyboardEvent) => {
|
||||
switch (e.key) {
|
||||
case 'ArrowDown':
|
||||
e.preventDefault()
|
||||
setActiveIndex(i => Math.min(i + 1, options.length - 1))
|
||||
break
|
||||
case 'ArrowUp':
|
||||
e.preventDefault()
|
||||
setActiveIndex(i => Math.max(i - 1, 0))
|
||||
break
|
||||
case 'Enter':
|
||||
e.preventDefault()
|
||||
onSelect(options[activeIndex])
|
||||
setIsOpen(false)
|
||||
break
|
||||
case 'Escape':
|
||||
setIsOpen(false)
|
||||
break
|
||||
}
|
||||
}
|
||||
|
||||
return (
|
||||
<div
|
||||
role="combobox"
|
||||
aria-expanded={isOpen}
|
||||
aria-haspopup="listbox"
|
||||
onKeyDown={handleKeyDown}
|
||||
>
|
||||
{/* Dropdown implementation */}
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
### Focus Management
|
||||
|
||||
```typescript
|
||||
export function Modal({ isOpen, onClose, children }: ModalProps) {
|
||||
const modalRef = useRef<HTMLDivElement>(null)
|
||||
const previousFocusRef = useRef<HTMLElement | null>(null)
|
||||
|
||||
useEffect(() => {
|
||||
if (isOpen) {
|
||||
// Save currently focused element
|
||||
previousFocusRef.current = document.activeElement as HTMLElement
|
||||
|
||||
// Focus modal
|
||||
modalRef.current?.focus()
|
||||
} else {
|
||||
// Restore focus when closing
|
||||
previousFocusRef.current?.focus()
|
||||
}
|
||||
}, [isOpen])
|
||||
|
||||
return isOpen ? (
|
||||
<div
|
||||
ref={modalRef}
|
||||
role="dialog"
|
||||
aria-modal="true"
|
||||
tabIndex={-1}
|
||||
onKeyDown={e => e.key === 'Escape' && onClose()}
|
||||
>
|
||||
{children}
|
||||
</div>
|
||||
) : null
|
||||
}
|
||||
```
|
||||
|
||||
**Remember**: Modern frontend patterns enable maintainable, performant user interfaces. Choose patterns that fit your project complexity.

## Code Patterns
|
||||
|
||||
### API Response Format (FastAPI)
|
||||
|
||||
```python
|
||||
from pydantic import BaseModel
|
||||
from typing import Generic, TypeVar, Optional
|
||||
|
||||
T = TypeVar('T')
|
||||
|
||||
class ApiResponse(BaseModel, Generic[T]):
|
||||
success: bool
|
||||
data: Optional[T] = None
|
||||
error: Optional[str] = None
|
||||
|
||||
@classmethod
|
||||
def ok(cls, data: T) -> "ApiResponse[T]":
|
||||
return cls(success=True, data=data)
|
||||
|
||||
@classmethod
|
||||
def fail(cls, error: str) -> "ApiResponse[T]":
|
||||
return cls(success=False, error=error)
|
||||
```
|
||||
|
||||
### Frontend API Calls (TypeScript)
|
||||
|
||||
```typescript
|
||||
interface ApiResponse<T> {
|
||||
success: boolean
|
||||
data?: T
|
||||
error?: string
|
||||
}
|
||||
|
||||
async function fetchApi<T>(
|
||||
endpoint: string,
|
||||
options?: RequestInit
|
||||
): Promise<ApiResponse<T>> {
|
||||
try {
|
||||
const response = await fetch(`/api${endpoint}`, {
|
||||
...options,
|
||||
headers: {
|
||||
'Content-Type': 'application/json',
|
||||
...options?.headers,
|
||||
},
|
||||
})
|
||||
|
||||
if (!response.ok) {
|
||||
return { success: false, error: `HTTP ${response.status}` }
|
||||
}
|
||||
|
||||
return await response.json()
|
||||
} catch (error) {
|
||||
return { success: false, error: String(error) }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Claude AI Integration (Structured Output)
|
||||
|
||||
```python
|
||||
from anthropic import Anthropic
|
||||
from pydantic import BaseModel
|
||||
|
||||
class AnalysisResult(BaseModel):
|
||||
summary: str
|
||||
key_points: list[str]
|
||||
confidence: float
|
||||
|
||||
async def analyze_with_claude(content: str) -> AnalysisResult:
|
||||
client = Anthropic()
|
||||
|
||||
response = client.messages.create(
|
||||
model="claude-sonnet-4-5-20250514",
|
||||
max_tokens=1024,
|
||||
messages=[{"role": "user", "content": content}],
|
||||
tools=[{
|
||||
"name": "provide_analysis",
|
||||
"description": "Provide structured analysis",
|
||||
"input_schema": AnalysisResult.model_json_schema()
|
||||
}],
|
||||
tool_choice={"type": "tool", "name": "provide_analysis"}
|
||||
)
|
||||
|
||||
# Extract tool use result
|
||||
tool_use = next(
|
||||
block for block in response.content
|
||||
if block.type == "tool_use"
|
||||
)
|
||||
|
||||
return AnalysisResult(**tool_use.input)
|
||||
```
|
||||
|
||||
### Custom Hooks (React)
|
||||
|
||||
```typescript
|
||||
import { useState, useCallback } from 'react'
|
||||
|
||||
interface UseApiState<T> {
|
||||
data: T | null
|
||||
loading: boolean
|
||||
error: string | null
|
||||
}
|
||||
|
||||
export function useApi<T>(
|
||||
fetchFn: () => Promise<ApiResponse<T>>
|
||||
) {
|
||||
const [state, setState] = useState<UseApiState<T>>({
|
||||
data: null,
|
||||
loading: false,
|
||||
error: null,
|
||||
})
|
||||
|
||||
const execute = useCallback(async () => {
|
||||
setState(prev => ({ ...prev, loading: true, error: null }))
|
||||
|
||||
const result = await fetchFn()
|
||||
|
||||
if (result.success) {
|
||||
setState({ data: result.data!, loading: false, error: null })
|
||||
} else {
|
||||
setState({ data: null, loading: false, error: result.error! })
|
||||
}
|
||||
}, [fetchFn])
|
||||
|
||||
return { ...state, execute }
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing Requirements
|
||||
|
||||
### Backend (pytest)
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
poetry run pytest tests/
|
||||
|
||||
# Run with coverage
|
||||
poetry run pytest tests/ --cov=. --cov-report=html
|
||||
|
||||
# Run specific test file
|
||||
poetry run pytest tests/test_auth.py -v
|
||||
```
|
||||
|
||||
**Test structure:**
|
||||
```python
|
||||
import pytest
|
||||
from httpx import AsyncClient
|
||||
from main import app
|
||||
|
||||
@pytest.fixture
|
||||
async def client():
|
||||
async with AsyncClient(app=app, base_url="http://test") as ac:
|
||||
yield ac
|
||||
|
||||
@pytest.mark.asyncio
|
||||
async def test_health_check(client: AsyncClient):
|
||||
response = await client.get("/health")
|
||||
assert response.status_code == 200
|
||||
assert response.json()["status"] == "healthy"
|
||||
```
|
||||
|
||||
### Frontend (React Testing Library)
|
||||
|
||||
```bash
|
||||
# Run tests
|
||||
npm run test
|
||||
|
||||
# Run with coverage
|
||||
npm run test -- --coverage
|
||||
|
||||
# Run E2E tests
|
||||
npm run test:e2e
|
||||
```
|
||||
|
||||
**Test structure:**
|
||||
```typescript
|
||||
import { render, screen, fireEvent } from '@testing-library/react'
|
||||
import { WorkspacePanel } from './WorkspacePanel'
|
||||
|
||||
describe('WorkspacePanel', () => {
|
||||
it('renders workspace correctly', () => {
|
||||
render(<WorkspacePanel />)
|
||||
expect(screen.getByRole('main')).toBeInTheDocument()
|
||||
})
|
||||
|
||||
it('handles session creation', async () => {
|
||||
render(<WorkspacePanel />)
|
||||
fireEvent.click(screen.getByText('New Session'))
|
||||
expect(await screen.findByText('Session created')).toBeInTheDocument()
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Deployment Workflow
|
||||
|
||||
### Pre-Deployment Checklist
|
||||
|
||||
- [ ] All tests passing locally
|
||||
- [ ] `npm run build` succeeds (frontend)
|
||||
- [ ] `poetry run pytest` passes (backend)
|
||||
- [ ] No hardcoded secrets
|
||||
- [ ] Environment variables documented
|
||||
- [ ] Database migrations ready
|
||||
|
||||
### Deployment Commands
|
||||
|
||||
```bash
|
||||
# Build and deploy frontend
|
||||
cd frontend && npm run build
|
||||
gcloud run deploy frontend --source .
|
||||
|
||||
# Build and deploy backend
|
||||
cd backend
|
||||
gcloud run deploy backend --source .
|
||||
```
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
# Frontend (.env.local)
|
||||
NEXT_PUBLIC_API_URL=https://api.example.com
|
||||
NEXT_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
|
||||
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJ...
|
||||
|
||||
# Backend (.env)
|
||||
DATABASE_URL=postgresql://...
|
||||
ANTHROPIC_API_KEY=sk-ant-...
|
||||
SUPABASE_URL=https://xxx.supabase.co
|
||||
SUPABASE_KEY=eyJ...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Critical Rules
|
||||
|
||||
1. **No emojis** in code, comments, or documentation
|
||||
2. **Immutability** - never mutate objects or arrays
|
||||
3. **TDD** - write tests before implementation
|
||||
4. **80% coverage** minimum
|
||||
5. **Many small files** - 200-400 lines typical, 800 max
|
||||
6. **No console.log** in production code
|
||||
7. **Proper error handling** with try/catch
|
||||
8. **Input validation** with Pydantic/Zod

## Security Checklist
|
||||
|
||||
### 1. Secrets Management
|
||||
|
||||
#### ❌ NEVER Do This
|
||||
```typescript
|
||||
const apiKey = "sk-proj-xxxxx" // Hardcoded secret
|
||||
const dbPassword = "password123" // In source code
|
||||
```
|
||||
|
||||
#### ✅ ALWAYS Do This
|
||||
```typescript
|
||||
const apiKey = process.env.OPENAI_API_KEY
|
||||
const dbUrl = process.env.DATABASE_URL
|
||||
|
||||
// Verify secrets exist
|
||||
if (!apiKey) {
|
||||
throw new Error('OPENAI_API_KEY not configured')
|
||||
}
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] No hardcoded API keys, tokens, or passwords
|
||||
- [ ] All secrets in environment variables
|
||||
- [ ] `.env.local` in .gitignore
|
||||
- [ ] No secrets in git history
|
||||
- [ ] Production secrets in hosting platform (Vercel, Railway)
|
||||
|
||||
### 2. Input Validation
|
||||
|
||||
#### Always Validate User Input
|
||||
```typescript
|
||||
import { z } from 'zod'
|
||||
|
||||
// Define validation schema
|
||||
const CreateUserSchema = z.object({
|
||||
email: z.string().email(),
|
||||
name: z.string().min(1).max(100),
|
||||
age: z.number().int().min(0).max(150)
|
||||
})
|
||||
|
||||
// Validate before processing
|
||||
export async function createUser(input: unknown) {
|
||||
try {
|
||||
const validated = CreateUserSchema.parse(input)
|
||||
return await db.users.create(validated)
|
||||
} catch (error) {
|
||||
if (error instanceof z.ZodError) {
|
||||
return { success: false, errors: error.errors }
|
||||
}
|
||||
throw error
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### File Upload Validation
|
||||
```typescript
|
||||
function validateFileUpload(file: File) {
|
||||
// Size check (5MB max)
|
||||
const maxSize = 5 * 1024 * 1024
|
||||
if (file.size > maxSize) {
|
||||
throw new Error('File too large (max 5MB)')
|
||||
}
|
||||
|
||||
// Type check
|
||||
const allowedTypes = ['image/jpeg', 'image/png', 'image/gif']
|
||||
if (!allowedTypes.includes(file.type)) {
|
||||
throw new Error('Invalid file type')
|
||||
}
|
||||
|
||||
// Extension check
|
||||
const allowedExtensions = ['.jpg', '.jpeg', '.png', '.gif']
|
||||
const extension = file.name.toLowerCase().match(/\.[^.]+$/)?.[0]
|
||||
if (!extension || !allowedExtensions.includes(extension)) {
|
||||
throw new Error('Invalid file extension')
|
||||
}
|
||||
|
||||
return true
|
||||
}
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] All user inputs validated with schemas
|
||||
- [ ] File uploads restricted (size, type, extension)
|
||||
- [ ] No direct use of user input in queries
|
||||
- [ ] Whitelist validation (not blacklist)
|
||||
- [ ] Error messages don't leak sensitive info
|
||||
|
||||
### 3. SQL Injection Prevention
|
||||
|
||||
#### ❌ NEVER Concatenate SQL
|
||||
```typescript
|
||||
// DANGEROUS - SQL Injection vulnerability
|
||||
const query = `SELECT * FROM users WHERE email = '${userEmail}'`
|
||||
await db.query(query)
|
||||
```
|
||||
|
||||
#### ✅ ALWAYS Use Parameterized Queries
|
||||
```typescript
|
||||
// Safe - parameterized query
|
||||
const { data } = await supabase
|
||||
.from('users')
|
||||
.select('*')
|
||||
.eq('email', userEmail)
|
||||
|
||||
// Or with raw SQL
|
||||
await db.query(
|
||||
'SELECT * FROM users WHERE email = $1',
|
||||
[userEmail]
|
||||
)
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] All database queries use parameterized queries
|
||||
- [ ] No string concatenation in SQL
|
||||
- [ ] ORM/query builder used correctly
|
||||
- [ ] Supabase queries properly sanitized
|
||||
|
||||
### 4. Authentication & Authorization
|
||||
|
||||
#### JWT Token Handling
|
||||
```typescript
|
||||
// ❌ WRONG: localStorage (vulnerable to XSS)
|
||||
localStorage.setItem('token', token)
|
||||
|
||||
// ✅ CORRECT: httpOnly cookies
|
||||
res.setHeader('Set-Cookie',
|
||||
`token=${token}; HttpOnly; Secure; SameSite=Strict; Max-Age=3600`)
|
||||
```
|
||||
|
||||
#### Authorization Checks
|
||||
```typescript
|
||||
export async function deleteUser(userId: string, requesterId: string) {
|
||||
// ALWAYS verify authorization first
|
||||
const requester = await db.users.findUnique({
|
||||
where: { id: requesterId }
|
||||
})
|
||||
|
||||
if (requester.role !== 'admin') {
|
||||
return NextResponse.json(
|
||||
{ error: 'Unauthorized' },
|
||||
{ status: 403 }
|
||||
)
|
||||
}
|
||||
|
||||
// Proceed with deletion
|
||||
await db.users.delete({ where: { id: userId } })
|
||||
}
|
||||
```
|
||||
|
||||
#### Row Level Security (Supabase)
|
||||
```sql
|
||||
-- Enable RLS on all tables
|
||||
ALTER TABLE users ENABLE ROW LEVEL SECURITY;
|
||||
|
||||
-- Users can only view their own data
|
||||
CREATE POLICY "Users view own data"
|
||||
ON users FOR SELECT
|
||||
USING (auth.uid() = id);
|
||||
|
||||
-- Users can only update their own data
|
||||
CREATE POLICY "Users update own data"
|
||||
ON users FOR UPDATE
|
||||
USING (auth.uid() = id);
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] Tokens stored in httpOnly cookies (not localStorage)
|
||||
- [ ] Authorization checks before sensitive operations
|
||||
- [ ] Row Level Security enabled in Supabase
|
||||
- [ ] Role-based access control implemented
|
||||
- [ ] Session management secure
|
||||
|
||||
### 5. XSS Prevention
|
||||
|
||||
#### Sanitize HTML
|
||||
```typescript
|
||||
import DOMPurify from 'isomorphic-dompurify'
|
||||
|
||||
// ALWAYS sanitize user-provided HTML
|
||||
function renderUserContent(html: string) {
|
||||
const clean = DOMPurify.sanitize(html, {
|
||||
ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'p'],
|
||||
ALLOWED_ATTR: []
|
||||
})
|
||||
return <div dangerouslySetInnerHTML={{ __html: clean }} />
|
||||
}
|
||||
```
|
||||
|
||||
#### Content Security Policy
|
||||
```typescript
|
||||
// next.config.js
|
||||
const securityHeaders = [
|
||||
{
|
||||
key: 'Content-Security-Policy',
|
||||
value: `
|
||||
default-src 'self';
|
||||
script-src 'self' 'unsafe-eval' 'unsafe-inline';
|
||||
style-src 'self' 'unsafe-inline';
|
||||
img-src 'self' data: https:;
|
||||
font-src 'self';
|
||||
connect-src 'self' https://api.example.com;
|
||||
`.replace(/\s{2,}/g, ' ').trim()
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] User-provided HTML sanitized
|
||||
- [ ] CSP headers configured
|
||||
- [ ] No unvalidated dynamic content rendering
|
||||
- [ ] React's built-in XSS protection used
|
||||
|
||||
### 6. CSRF Protection
|
||||
|
||||
#### CSRF Tokens
|
||||
```typescript
|
||||
import { csrf } from '@/lib/csrf'
|
||||
|
||||
export async function POST(request: Request) {
|
||||
const token = request.headers.get('X-CSRF-Token')
|
||||
|
||||
if (!csrf.verify(token)) {
|
||||
return NextResponse.json(
|
||||
{ error: 'Invalid CSRF token' },
|
||||
{ status: 403 }
|
||||
)
|
||||
}
|
||||
|
||||
// Process request
|
||||
}
|
||||
```
|
||||
|
||||
#### SameSite Cookies
|
||||
```typescript
|
||||
res.setHeader('Set-Cookie',
|
||||
`session=${sessionId}; HttpOnly; Secure; SameSite=Strict`)
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] CSRF tokens on state-changing operations
|
||||
- [ ] SameSite=Strict on all cookies
|
||||
- [ ] Double-submit cookie pattern implemented
|
||||
|
||||
### 7. Rate Limiting
|
||||
|
||||
#### API Rate Limiting
|
||||
```typescript
|
||||
import rateLimit from 'express-rate-limit'
|
||||
|
||||
const limiter = rateLimit({
|
||||
windowMs: 15 * 60 * 1000, // 15 minutes
|
||||
max: 100, // 100 requests per window
|
||||
message: 'Too many requests'
|
||||
})
|
||||
|
||||
// Apply to routes
|
||||
app.use('/api/', limiter)
|
||||
```
|
||||
|
||||
#### Expensive Operations
|
||||
```typescript
|
||||
// Aggressive rate limiting for searches
|
||||
const searchLimiter = rateLimit({
|
||||
windowMs: 60 * 1000, // 1 minute
|
||||
max: 10, // 10 requests per minute
|
||||
message: 'Too many search requests'
|
||||
})
|
||||
|
||||
app.use('/api/search', searchLimiter)
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] Rate limiting on all API endpoints
|
||||
- [ ] Stricter limits on expensive operations
|
||||
- [ ] IP-based rate limiting
|
||||
- [ ] User-based rate limiting (authenticated)
|
||||
|
||||
### 8. Sensitive Data Exposure
|
||||
|
||||
#### Logging
|
||||
```typescript
|
||||
// ❌ WRONG: Logging sensitive data
|
||||
console.log('User login:', { email, password })
|
||||
console.log('Payment:', { cardNumber, cvv })
|
||||
|
||||
// ✅ CORRECT: Redact sensitive data
|
||||
console.log('User login:', { email, userId })
|
||||
console.log('Payment:', { last4: card.last4, userId })
|
||||
```
|
||||
|
||||
#### Error Messages
|
||||
```typescript
|
||||
// ❌ WRONG: Exposing internal details
|
||||
catch (error) {
|
||||
return NextResponse.json(
|
||||
{ error: error.message, stack: error.stack },
|
||||
{ status: 500 }
|
||||
)
|
||||
}
|
||||
|
||||
// ✅ CORRECT: Generic error messages
|
||||
catch (error) {
|
||||
console.error('Internal error:', error)
|
||||
return NextResponse.json(
|
||||
{ error: 'An error occurred. Please try again.' },
|
||||
{ status: 500 }
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] No passwords, tokens, or secrets in logs
|
||||
- [ ] Error messages generic for users
|
||||
- [ ] Detailed errors only in server logs
|
||||
- [ ] No stack traces exposed to users
|
||||
|
||||
### 9. Blockchain Security (Solana)
|
||||
|
||||
#### Wallet Verification
|
||||
```typescript
|
||||
import { verify } from '@solana/web3.js'
|
||||
|
||||
async function verifyWalletOwnership(
|
||||
publicKey: string,
|
||||
signature: string,
|
||||
message: string
|
||||
) {
|
||||
try {
|
||||
const isValid = verify(
|
||||
Buffer.from(message),
|
||||
Buffer.from(signature, 'base64'),
|
||||
Buffer.from(publicKey, 'base64')
|
||||
)
|
||||
return isValid
|
||||
} catch (error) {
|
||||
return false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Transaction Verification
|
||||
```typescript
|
||||
async function verifyTransaction(transaction: Transaction) {
|
||||
// Verify recipient
|
||||
if (transaction.to !== expectedRecipient) {
|
||||
throw new Error('Invalid recipient')
|
||||
}
|
||||
|
||||
// Verify amount
|
||||
if (transaction.amount > maxAmount) {
|
||||
throw new Error('Amount exceeds limit')
|
||||
}
|
||||
|
||||
// Verify user has sufficient balance
|
||||
const balance = await getBalance(transaction.from)
|
||||
if (balance < transaction.amount) {
|
||||
throw new Error('Insufficient balance')
|
||||
}
|
||||
|
||||
return true
|
||||
}
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] Wallet signatures verified
|
||||
- [ ] Transaction details validated
|
||||
- [ ] Balance checks before transactions
|
||||
- [ ] No blind transaction signing
|
||||
|
||||
### 10. Dependency Security
|
||||
|
||||
#### Regular Updates
|
||||
```bash
|
||||

||||
npm audit
|
||||
|
||||
# Fix automatically fixable issues
|
||||
npm audit fix
|
||||
|
||||
# Update dependencies
|
||||
npm update
|
||||
|
||||
# Check for outdated packages
|
||||
npm outdated
|
||||
```
|
||||
|
||||
#### Lock Files
|
||||
```bash
|
||||
# ALWAYS commit lock files
|
||||
git add package-lock.json
|
||||
|
||||
# Use in CI/CD for reproducible builds
|
||||
npm ci # Instead of npm install
|
||||
```
|
||||
|
||||
#### Verification Steps
|
||||
- [ ] Dependencies up to date
|
||||
- [ ] No known vulnerabilities (npm audit clean)
|
||||
- [ ] Lock files committed
|
||||
- [ ] Dependabot enabled on GitHub
|
||||
- [ ] Regular security updates
|
||||
|
||||
## Security Testing
|
||||
|
||||
### Automated Security Tests
|
||||
```typescript
|
||||
// Test authentication
|
||||
test('requires authentication', async () => {
|
||||
const response = await fetch('/api/protected')
|
||||
expect(response.status).toBe(401)
|
||||
})
|
||||
|
||||
// Test authorization
|
||||
test('requires admin role', async () => {
|
||||
const response = await fetch('/api/admin', {
|
||||
headers: { Authorization: `Bearer ${userToken}` }
|
||||
})
|
||||
expect(response.status).toBe(403)
|
||||
})
|
||||
|
||||
// Test input validation
|
||||
test('rejects invalid input', async () => {
|
||||
const response = await fetch('/api/users', {
|
||||
method: 'POST',
|
||||
body: JSON.stringify({ email: 'not-an-email' })
|
||||
})
|
||||
expect(response.status).toBe(400)
|
||||
})
|
||||
|
||||
// Test rate limiting
|
||||
test('enforces rate limits', async () => {
|
||||
const requests = Array(101).fill(null).map(() =>
|
||||
fetch('/api/endpoint')
|
||||
)
|
||||
|
||||
const responses = await Promise.all(requests)
|
||||
const tooManyRequests = responses.filter(r => r.status === 429)
|
||||
|
||||
expect(tooManyRequests.length).toBeGreaterThan(0)
|
||||
})
|
||||
```

# Strategic Compact Suggester
|

# Runs on PreToolUse or periodically to suggest manual compaction at logical intervals
|
||||
#
|
||||
# Why manual over auto-compact:
|
||||
# - Auto-compact happens at arbitrary points, often mid-task
|
||||
# - Strategic compacting preserves context through logical phases
|
||||
# - Compact after exploration, before execution
|
||||
# - Compact after completing a milestone, before starting next
|

|
||||
# Hook config (in ~/.claude/settings.json):

# Using Three.js and React Three Fiber in Remotion
|
||||
|
||||
Follow React Three Fiber and Three.js best practices.
|
||||
Only the following Remotion-specific rules need to be followed:
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the `@remotion/three` package needs to be installed.
|
||||
If it is not, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/three # If project uses npm
|
||||
bunx remotion add @remotion/three # If project uses bun
|
||||
yarn remotion add @remotion/three # If project uses yarn
|
||||
pnpm exec remotion add @remotion/three # If project uses pnpm
|
||||
```
|
||||
|
||||
## Using ThreeCanvas
|
||||
|
||||
You MUST wrap 3D content in `<ThreeCanvas>` and include proper lighting.
|
||||
`<ThreeCanvas>` MUST have a `width` and `height` prop.
|
||||
|
||||
```tsx
|
||||
import { ThreeCanvas } from "@remotion/three";
|
||||
import { useVideoConfig } from "remotion";
|
||||
|
||||
const { width, height } = useVideoConfig();
|
||||
|
||||
<ThreeCanvas width={width} height={height}>
|
||||
<ambientLight intensity={0.4} />
|
||||
<directionalLight position={[5, 5, 5]} intensity={0.8} />
|
||||
<mesh>
|
||||
<sphereGeometry args={[1, 32, 32]} />
|
||||
<meshStandardMaterial color="red" />
|
||||
</mesh>
|
||||
</ThreeCanvas>
|
||||
```
|
||||
|
||||
## No animations not driven by `useCurrentFrame()`
|
||||
|
||||
Shaders, models etc MUST NOT animate by themselves.
|
||||
No animations are allowed unless they are driven by `useCurrentFrame()`.
|
||||
Otherwise, it will cause flickering during rendering.
|
||||
|
||||
Using `useFrame()` from `@react-three/fiber` is forbidden.
|
||||
|
||||
## Animate using `useCurrentFrame()`
|
||||
|
||||
Use `useCurrentFrame()` to perform animations.
|
||||
|
||||
```tsx
|
||||
const frame = useCurrentFrame();
|
||||
const rotationY = frame * 0.02;
|
||||
|
||||
<mesh rotation={[0, rotationY, 0]}>
|
||||
<boxGeometry args={[2, 2, 2]} />
|
||||
<meshStandardMaterial color="#4a9eff" />
|
||||
</mesh>
|
||||
```
|
||||
|
||||
## Using `<Sequence>` inside `<ThreeCanvas>`
|
||||
|
||||
The `layout` prop of any `<Sequence>` inside a `<ThreeCanvas>` must be set to `none`.
|
||||
|
||||
```tsx
|
||||
import { Sequence } from "remotion";
|
||||
import { ThreeCanvas } from "@remotion/three";
|
||||
|
||||
const { width, height } = useVideoConfig();
|
||||
|
||||
<ThreeCanvas width={width} height={height}>
|
||||
<Sequence layout="none">
|
||||
<mesh>
|
||||
<boxGeometry args={[2, 2, 2]} />
|
||||
<meshStandardMaterial color="#4a9eff" />
|
||||
</mesh>
|
||||
</Sequence>
|
||||
</ThreeCanvas>
|
||||
```

tags: animations, transitions, frames, useCurrentFrame
|
||||
---
|
||||
|
||||
All animations MUST be driven by the `useCurrentFrame()` hook.
|
||||
Write animations in seconds and multiply them by the `fps` value from `useVideoConfig()`.
|
||||
|
||||
```tsx
|
||||
import { useCurrentFrame } from "remotion";
|
||||
|
||||
export const FadeIn = () => {
|
||||
const frame = useCurrentFrame();
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
const opacity = interpolate(frame, [0, 2 * fps], [0, 1], {
|
||||
extrapolateRight: 'clamp',
|
||||
});
|
||||
|
||||
return (
|
||||
<div style={{ opacity }}>Hello World!</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
CSS transitions or animations are FORBIDDEN - they will not render correctly.
|
||||
Tailwind animation class names are FORBIDDEN - they will not render correctly.

# Importing assets in Remotion
|
||||
|
||||
## The public folder
|
||||
|
||||
Place assets in the `public/` folder at your project root.
|
||||
|
||||
## Using staticFile()
|
||||
|
||||
You MUST use `staticFile()` to reference files from the `public/` folder:
|
||||
|
||||
```tsx
|
||||
import {Img, staticFile} from 'remotion';
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <Img src={staticFile('logo.png')} />;
|
||||
};
|
||||
```
|
||||
|
||||
The function returns an encoded URL that works correctly when deploying to subdirectories.
|
||||
|
||||
## Using with components
|
||||
|
||||
**Images:**
|
||||
|
||||
```tsx
|
||||
import {Img, staticFile} from 'remotion';
|
||||
|
||||
<Img src={staticFile('photo.png')} />;
|
||||
```
|
||||
|
||||
**Videos:**
|
||||
|
||||
```tsx
|
||||
import {Video} from '@remotion/media';
|
||||
import {staticFile} from 'remotion';
|
||||
|
||||
<Video src={staticFile('clip.mp4')} />;
|
||||
```
|
||||
|
||||
**Audio:**
|
||||
|
||||
```tsx
|
||||
import {Audio} from '@remotion/media';
|
||||
import {staticFile} from 'remotion';
|
||||
|
||||
<Audio src={staticFile('music.mp3')} />;
|
||||
```
|
||||
|
||||
**Fonts:**
|
||||
|
||||
```tsx
|
||||
import {staticFile} from 'remotion';
|
||||
|
||||
const fontFamily = new FontFace('MyFont', `url(${staticFile('font.woff2')})`);
|
||||
await fontFamily.load();
|
||||
document.fonts.add(fontFamily);
|
||||
```
|
||||
|
||||
## Remote URLs
|
||||
|
||||
Remote URLs can be used directly without `staticFile()`:
|
||||
|
||||
```tsx
|
||||
<Img src="https://example.com/image.png" />
|
||||
<Video src="https://remotion.media/video.mp4" />
|
||||
```
|
||||
|
||||
## Important notes
|
||||
|
||||
- Remotion components (`<Img>`, `<Video>`, `<Audio>`) ensure assets are fully loaded before rendering
|
||||
- Special characters in filenames (`#`, `?`, `&`) are automatically encoded

# Using audio in Remotion
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/media package needs to be installed.
|
||||
If it is not installed, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/media # If project uses npm
|
||||
bunx remotion add @remotion/media # If project uses bun
|
||||
yarn remotion add @remotion/media # If project uses yarn
|
||||
pnpm exec remotion add @remotion/media # If project uses pnpm
|
||||
```
|
||||
|
||||
## Importing Audio
|
||||
|
||||
Use `<Audio>` from `@remotion/media` to add audio to your composition.
|
||||
|
||||
```tsx
|
||||
import { Audio } from "@remotion/media";
|
||||
import { staticFile } from "remotion";
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <Audio src={staticFile("audio.mp3")} />;
|
||||
};
|
||||
```
|
||||
|
||||
Remote URLs are also supported:
|
||||
|
||||
```tsx
|
||||
<Audio src="https://remotion.media/audio.mp3" />
|
||||
```
|
||||
|
||||
By default, audio plays from the start, at full volume and full length.
|
||||
Multiple audio tracks can be layered by adding multiple `<Audio>` components.
|
||||
|
||||
## Trimming
|
||||
|
||||
Use `trimBefore` and `trimAfter` to remove portions of the audio. Values are in frames.
|
||||
|
||||
```tsx
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
trimBefore={2 * fps} // Skip the first 2 seconds
|
||||
trimAfter={10 * fps} // End at the 10 second mark
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
The audio still starts playing at the beginning of the composition - only the specified portion is played.
|
||||
|
||||
## Delaying
|
||||
|
||||
Wrap the audio in a `<Sequence>` to delay when it starts:
|
||||
|
||||
```tsx
|
||||
import { Sequence, staticFile } from "remotion";
|
||||
import { Audio } from "@remotion/media";
|
||||
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Sequence from={1 * fps}>
|
||||
<Audio src={staticFile("audio.mp3")} />
|
||||
</Sequence>
|
||||
);
|
||||
```
|
||||
|
||||
The audio will start playing after 1 second.
|
||||
|
||||
## Volume
|
||||
|
||||
Set a static volume (0 to 1):
|
||||
|
||||
```tsx
|
||||
<Audio src={staticFile("audio.mp3")} volume={0.5} />
|
||||
```
|
||||
|
||||
Or use a callback for dynamic volume based on the current frame:
|
||||
|
||||
```tsx
|
||||
import { interpolate } from "remotion";
|
||||
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
volume={(f) =>
|
||||
interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
|
||||
}
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
The value of `f` starts at 0 when the audio begins to play, not the composition frame.
|
||||
|
||||
## Muting
|
||||
|
||||
Use `muted` to silence the audio. It can be set dynamically:
|
||||
|
||||
```tsx
|
||||
const frame = useCurrentFrame();
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
muted={frame >= 2 * fps && frame <= 4 * fps} // Mute between 2s and 4s
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
## Speed
|
||||
|
||||
Use `playbackRate` to change the playback speed:
|
||||
|
||||
```tsx
|
||||
<Audio src={staticFile("audio.mp3")} playbackRate={2} /> {/* 2x speed */}
|
||||
<Audio src={staticFile("audio.mp3")} playbackRate={0.5} /> {/* Half speed */}
|
||||
```
|
||||
|
||||
Reverse playback is not supported.
|
||||
|
||||
## Looping
|
||||
|
||||
Use `loop` to loop the audio indefinitely:
|
||||
|
||||
```tsx
|
||||
<Audio src={staticFile("audio.mp3")} loop />
|
||||
```
|
||||
|
||||
Use `loopVolumeCurveBehavior` to control how the frame count behaves when looping:
|
||||
|
||||
- `"repeat"`: Frame count resets to 0 each loop (default)
|
||||
- `"extend"`: Frame count continues incrementing
|
||||
|
||||
```tsx
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
loop
|
||||
loopVolumeCurveBehavior="extend"
|
||||
volume={(f) => interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
|
||||
/>
|
||||
```
|
||||
|
||||
## Pitch
|
||||
|
||||
Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
|
||||
|
||||
```tsx
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
toneFrequency={1.5} // Higher pitch
|
||||
/>
|
||||
<Audio
|
||||
src={staticFile("audio.mp3")}
|
||||
toneFrequency={0.8} // Lower pitch
|
||||
/>
|
||||
```
|
||||
|
||||
Pitch shifting only works during server-side rendering, not in the Remotion Studio preview or in the `<Player />`.

# Using calculateMetadata
|
||||
|
||||
Use `calculateMetadata` on a `<Composition>` to dynamically set duration, dimensions, and transform props before rendering.
|
||||
|
||||
```tsx
|
||||
<Composition id="MyComp" component={MyComponent} durationInFrames={300} fps={30} width={1920} height={1080} defaultProps={{videoSrc: 'https://remotion.media/video.mp4'}} calculateMetadata={calculateMetadata} />
|
||||
```
|
||||
|
||||
## Setting duration based on a video
|
||||
|
||||
Use the `getMediaMetadata()` function from the mediabunny/metadata skill to get the video duration:
|
||||
|
||||
```tsx
|
||||
import {CalculateMetadataFunction} from 'remotion';
|
||||
import {getMediaMetadata} from '../get-media-metadata';
|
||||
|
||||
const calculateMetadata: CalculateMetadataFunction<Props> = async ({props}) => {
|
||||
const {durationInSeconds} = await getMediaMetadata(props.videoSrc);
|
||||
|
||||
return {
|
||||
durationInFrames: Math.ceil(durationInSeconds * 30),
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
## Matching dimensions of a video
|
||||
|
||||
```tsx
|
||||
const calculateMetadata: CalculateMetadataFunction<Props> = async ({props}) => {
|
||||
const {durationInSeconds, dimensions} = await getMediaMetadata(props.videoSrc);
|
||||
|
||||
return {
|
||||
durationInFrames: Math.ceil(durationInSeconds * 30),
|
||||
width: dimensions?.width ?? 1920,
|
||||
height: dimensions?.height ?? 1080,
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
## Setting duration based on multiple videos
|
||||
|
||||
```tsx
|
||||
const calculateMetadata: CalculateMetadataFunction<Props> = async ({props}) => {
|
||||
const metadataPromises = props.videos.map((video) => getMediaMetadata(video.src));
|
||||
const allMetadata = await Promise.all(metadataPromises);
|
||||
|
||||
const totalDuration = allMetadata.reduce((sum, meta) => sum + meta.durationInSeconds, 0);
|
||||
|
||||
return {
|
||||
durationInFrames: Math.ceil(totalDuration * 30),
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
## Setting a default outName
|
||||
|
||||
Set the default output filename based on props:
|
||||
|
||||
```tsx
|
||||
const calculateMetadata: CalculateMetadataFunction<Props> = async ({props}) => {
|
||||
return {
|
||||
defaultOutName: `video-${props.id}.mp4`,
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
## Transforming props
|
||||
|
||||
Fetch data or transform props before rendering:
|
||||
|
||||
```tsx
|
||||
const calculateMetadata: CalculateMetadataFunction<Props> = async ({props, abortSignal}) => {
|
||||
const response = await fetch(props.dataUrl, {signal: abortSignal});
|
||||
const data = await response.json();
|
||||
|
||||
return {
|
||||
props: {
|
||||
...props,
|
||||
fetchedData: data,
|
||||
},
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
The `abortSignal` cancels stale requests when props change in the Studio.
|
||||
|
||||
## Return value
|
||||
|
||||
All fields are optional. Returned values override the `<Composition>` props:
|
||||
|
||||
- `durationInFrames`: Number of frames
|
||||
- `width`: Composition width in pixels
|
||||
- `height`: Composition height in pixels
|
||||
- `fps`: Frames per second
|
||||
- `props`: Transformed props passed to the component
|
||||
- `defaultOutName`: Default output filename
|
||||
- `defaultCodec`: Default codec for rendering

# Checking if a video can be decoded
|
||||
|
||||
Use Mediabunny to check if a video can be decoded by the browser before attempting to play it.
|
||||
|
||||
## The `canDecode()` function
|
||||
|
||||
This function can be copy-pasted into any project.
|
||||
|
||||
```tsx
|
||||
import { Input, ALL_FORMATS, UrlSource } from "mediabunny";
|
||||
|
||||
export const canDecode = async (src: string) => {
|
||||
const input = new Input({
|
||||
formats: ALL_FORMATS,
|
||||
source: new UrlSource(src, {
|
||||
getRetryDelay: () => null,
|
||||
}),
|
||||
});
|
||||
|
||||
try {
|
||||
await input.getFormat();
|
||||
} catch {
|
||||
return false;
|
||||
}
|
||||
|
||||
const videoTrack = await input.getPrimaryVideoTrack();
|
||||
if (videoTrack && !(await videoTrack.canDecode())) {
|
||||
return false;
|
||||
}
|
||||
|
||||
const audioTrack = await input.getPrimaryAudioTrack();
|
||||
if (audioTrack && !(await audioTrack.canDecode())) {
|
||||
return false;
|
||||
}
|
||||
|
||||
return true;
|
||||
};
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```tsx
|
||||
const src = "https://remotion.media/video.mp4";
|
||||
const isDecodable = await canDecode(src);
|
||||
|
||||
if (isDecodable) {
|
||||
console.log("Video can be decoded");
|
||||
} else {
|
||||
console.log("Video cannot be decoded by this browser");
|
||||
}
|
||||
```
|
||||
|
||||
## Using with Blob
|
||||
|
||||
For file uploads or drag-and-drop, use `BlobSource`:
|
||||
|
||||
```tsx
|
||||
import { Input, ALL_FORMATS, BlobSource } from "mediabunny";
|
||||
|
||||
export const canDecodeBlob = async (blob: Blob) => {
|
||||
const input = new Input({
|
||||
formats: ALL_FORMATS,
|
||||
source: new BlobSource(blob),
|
||||
});
|
||||
|
||||
// Same validation logic as above
|
||||
};
|
||||
```

# Charts in Remotion
|
||||
|
||||
You can create bar charts in Remotion by using regular React code - HTML and SVG is allowed, as well as D3.js.
|
||||
|
||||
## No animations not powered by `useCurrentFrame()`
|
||||
|
||||
Disable all animations by third party libraries.
|
||||
They will cause flickering during rendering.
|
||||
Instead, drive all animations from `useCurrentFrame()`.
|
||||
|
||||
## Bar Chart Animations
|
||||
|
||||
See [Bar Chart Example](assets/charts/bar-chart.tsx) for a basic example implmentation.
|
||||
|
||||
### Staggered Bars
|
||||
|
||||
You can animate the height of the bars and stagger them like this:
|
||||
|
||||
```tsx
|
||||
const STAGGER_DELAY = 5;
|
||||
const frame = useCurrentFrame();
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
const bars = data.map((item, i) => {
|
||||
const delay = i * STAGGER_DELAY;
|
||||
const height = spring({
|
||||
frame,
|
||||
fps,
|
||||
delay,
|
||||
config: {damping: 200},
|
||||
});
|
||||
return <div style={{height: height * item.value}} />;
|
||||
});
|
||||
```
|
||||
|
||||
## Pie Chart Animation
|
||||
|
||||
Animate segments using stroke-dashoffset, starting from 12 o'clock.
|
||||
|
||||
```tsx
|
||||
const frame = useCurrentFrame();
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
const progress = interpolate(frame, [0, 100], [0, 1]);
|
||||
|
||||
const circumference = 2 * Math.PI * radius;
|
||||
const segmentLength = (value / total) * circumference;
|
||||
const offset = interpolate(progress, [0, 1], [segmentLength, 0]);
|
||||
|
||||
<circle r={radius} cx={center} cy={center} fill="none" stroke={color} strokeWidth={strokeWidth} strokeDasharray={`${segmentLength} ${circumference}`} strokeDashoffset={offset} transform={`rotate(-90 ${center} ${center})`} />;
|
||||
```

|

|
||||
A `<Composition>` defines the component, width, height, fps and duration of a renderable video.
|
||||
|
||||
It normally is placed in the `src/Root.tsx` file.
|
||||
|
||||
```tsx
|
||||
import { Composition } from "remotion";
|
||||
import { MyComposition } from "./MyComposition";
|
||||
|
||||
export const RemotionRoot = () => {
|
||||
return (
|
||||
<Composition
|
||||
id="MyComposition"
|
||||
component={MyComposition}
|
||||
durationInFrames={100}
|
||||
fps={30}
|
||||
width={1080}
|
||||
height={1080}
|
||||
/>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Default Props
|
||||
|
||||
Pass `defaultProps` to provide initial values for your component.
|
||||
Values must be JSON-serializable (`Date`, `Map`, `Set`, and `staticFile()` are supported).
|
||||
|
||||
```tsx
|
||||
import { Composition } from "remotion";
|
||||
import { MyComposition, MyCompositionProps } from "./MyComposition";
|
||||
|
||||
export const RemotionRoot = () => {

||||
return (
|
||||
<Composition
|
||||
id="MyComposition"
|
||||
component={MyComposition}
|
||||
durationInFrames={100}
|
||||
fps={30}
|
||||
width={1080}
|
||||
height={1080}
|
||||
defaultProps={{
|
||||
title: "Hello World",
|
||||
color: "#ff0000",
|
||||
} satisfies MyCompositionProps}
|
||||
/>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
Use `type` declarations for props rather than `interface` to ensure `defaultProps` type safety.
|
||||
|
||||
## Folders
|
||||
|
||||
Use `<Folder>` to organize compositions in the sidebar.
|
||||
Folder names can only contain letters, numbers, and hyphens.
|
||||
|
||||
```tsx
|
||||
import { Composition, Folder } from "remotion";
|
||||
|
||||
export const RemotionRoot = () => {
|
||||
return (
|
||||
<>
|
||||
<Folder name="Marketing">
|
||||
<Composition id="Promo" /* ... */ />
|
||||
<Composition id="Ad" /* ... */ />
|
||||
</Folder>
|
||||
<Folder name="Social">
|
||||
<Folder name="Instagram">
|
||||
<Composition id="Story" /* ... */ />
|
||||
<Composition id="Reel" /* ... */ />
|
||||
</Folder>
|
||||
</Folder>
|
||||
</>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Stills
|
||||
|
||||
Use `<Still>` for single-frame images. It does not require `durationInFrames` or `fps`.
|
||||
|
||||
```tsx
|
||||
import { Still } from "remotion";
|
||||
import { Thumbnail } from "./Thumbnail";
|
||||
|
||||
export const RemotionRoot = () => {
|
||||
return (
|
||||
<Still
|
||||
id="Thumbnail"
|
||||
component={Thumbnail}
|
||||
width={1280}
|
||||
height={720}
|
||||
/>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Calculate Metadata
|
||||
|
||||
Use `calculateMetadata` to make dimensions, duration, or props dynamic based on data.
|
||||
|
||||
```tsx
|
||||
import { Composition, CalculateMetadataFunction } from "remotion";
|
||||
import { MyComposition, MyCompositionProps } from "./MyComposition";
|
||||
|
||||
const calculateMetadata: CalculateMetadataFunction<MyCompositionProps> = async ({
|
||||
props,
|
||||
abortSignal,
|
||||
}) => {
|
||||
const data = await fetch(`https://api.example.com/video/${props.videoId}`, {
|
||||
signal: abortSignal,
|
||||
}).then((res) => res.json());
|
||||
|
||||
return {
|
||||
durationInFrames: Math.ceil(data.duration * 30),
|
||||
props: {
|
||||
...props,
|
||||
videoUrl: data.url,
|
||||
},
|
||||
};
|
||||
};
|
||||
|
||||
export const RemotionRoot = () => {
|
||||
return (
|
||||
<Composition
|
||||
id="MyComposition"
|
||||
component={MyComposition}
|
||||
durationInFrames={100} // Placeholder, will be overridden
|
||||
fps={30}
|
||||
width={1080}
|
||||
height={1080}
|
||||
defaultProps={{ videoId: "abc123" }}
|
||||
calculateMetadata={calculateMetadata}
|
||||
/>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
The function can return `props`, `durationInFrames`, `width`, `height`, `fps`, and codec-related defaults. It runs once before rendering begins.

# Displaying captions in Remotion
|
||||
|
||||
This guide explains how to display captions in Remotion, assuming you already have captions in the `Caption` format.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/captions package needs to be installed.
|
||||
If it is not installed, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/captions # If project uses npm
|
||||
bunx remotion add @remotion/captions # If project uses bun
|
||||
yarn remotion add @remotion/captions # If project uses yarn
|
||||
pnpm exec remotion add @remotion/captions # If project uses pnpm
|
||||
```
|
||||
|
||||
## Creating pages
|
||||
|
||||
Use `createTikTokStyleCaptions()` to group captions into pages. The `combineTokensWithinMilliseconds` option controls how many words appear at once:
|
||||
|
||||
```tsx
|
||||
import {useMemo} from 'react';
|
||||
import {createTikTokStyleCaptions} from '@remotion/captions';
|
||||
import type {Caption} from '@remotion/captions';
|
||||
|
||||
// How often captions should switch (in milliseconds)
|
||||
// Higher values = more words per page
|
||||
// Lower values = fewer words (more word-by-word)
|
||||
const SWITCH_CAPTIONS_EVERY_MS = 1200;
|
||||
|
||||
const {pages} = useMemo(() => {
|
||||
return createTikTokStyleCaptions({
|
||||
captions,
|
||||
combineTokensWithinMilliseconds: SWITCH_CAPTIONS_EVERY_MS,
|
||||
});
|
||||
}, [captions]);
|
||||
```
|
||||
|
||||
## Rendering with Sequences
|
||||
|
||||
Map over the pages and render each one in a `<Sequence>`. Calculate the start frame and duration from the page timing:
|
||||
|
||||
```tsx
|
||||
import {Sequence, useVideoConfig, AbsoluteFill} from 'remotion';
|
||||
import type {TikTokPage} from '@remotion/captions';
|
||||
|
||||
const CaptionedContent: React.FC = () => {
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
return (
|
||||
<AbsoluteFill>
|
||||
{pages.map((page, index) => {
|
||||
const nextPage = pages[index + 1] ?? null;
|
||||
const startFrame = (page.startMs / 1000) * fps;
|
||||
const endFrame = Math.min(
|
||||
nextPage ? (nextPage.startMs / 1000) * fps : Infinity,
|
||||
startFrame + (SWITCH_CAPTIONS_EVERY_MS / 1000) * fps,
|
||||
);
|
||||
const durationInFrames = endFrame - startFrame;
|
||||
|
||||
if (durationInFrames <= 0) {
|
||||
return null;
|
||||
}
|
||||
|
||||
return (
|
||||
<Sequence
|
||||
key={index}
|
||||
from={startFrame}
|
||||
durationInFrames={durationInFrames}
|
||||
>
|
||||
<CaptionPage page={page} />
|
||||
</Sequence>
|
||||
);
|
||||
})}
|
||||
</AbsoluteFill>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## Word highlighting
|
||||
|
||||
A caption page contains `tokens` which you can use to highlight the currently spoken word:
|
||||
|
||||
```tsx
|
||||
import {AbsoluteFill, useCurrentFrame, useVideoConfig} from 'remotion';
|
||||
import type {TikTokPage} from '@remotion/captions';
|
||||
|
||||
const HIGHLIGHT_COLOR = '#39E508';
|
||||
|
||||
const CaptionPage: React.FC<{page: TikTokPage}> = ({page}) => {
|
||||
const frame = useCurrentFrame();
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
// Current time relative to the start of the sequence
|
||||
const currentTimeMs = (frame / fps) * 1000;
|
||||
// Convert to absolute time by adding the page start
|
||||
const absoluteTimeMs = page.startMs + currentTimeMs;
|
||||
|
||||
return (
|
||||
<AbsoluteFill style={{justifyContent: 'center', alignItems: 'center'}}>
|
||||
<div style={{fontSize: 80, fontWeight: 'bold', whiteSpace: 'pre'}}>
|
||||
{page.tokens.map((token) => {
|
||||
const isActive =
|
||||
token.fromMs <= absoluteTimeMs && token.toMs > absoluteTimeMs;
|
||||
|
||||
return (
|
||||
<span
|
||||
key={token.fromMs}
|
||||
style={{color: isActive ? HIGHLIGHT_COLOR : 'white'}}
|
||||
>
|
||||
{token.text}
|
||||
</span>
|
||||
);
|
||||
})}
|
||||
</div>
|
||||
</AbsoluteFill>
|
||||
);
|
||||
};
|
||||
```

# Extracting frames from videos
|
||||
|
||||
Use Mediabunny to extract frames from videos at specific timestamps. This is useful for generating thumbnails, filmstrips, or processing individual frames.
|
||||
|
||||
## The `extractFrames()` function
|
||||
|
||||
This function can be copy-pasted into any project.
|
||||
|
||||
```tsx
|
||||
import {
|
||||
ALL_FORMATS,
|
||||
Input,
|
||||
UrlSource,
|
||||
VideoSample,
|
||||
VideoSampleSink,
|
||||
} from "mediabunny";
|
||||
|
||||
type Options = {
|
||||
track: { width: number; height: number };
|
||||
container: string;
|
||||
durationInSeconds: number | null;
|
||||
};
|
||||
|
||||
export type ExtractFramesTimestampsInSecondsFn = (
|
||||
options: Options
|
||||
) => Promise<number[]> | number[];
|
||||
|
||||
export type ExtractFramesProps = {
|
||||
src: string;
|
||||
timestampsInSeconds: number[] | ExtractFramesTimestampsInSecondsFn;
|
||||
onVideoSample: (sample: VideoSample) => void;
|
||||
signal?: AbortSignal;
|
||||
};
|
||||
|
||||
export async function extractFrames({
|
||||
src,
|
||||
timestampsInSeconds,
|
||||
onVideoSample,
|
||||
signal,
|
||||
}: ExtractFramesProps): Promise<void> {
|
||||
using input = new Input({
|
||||
formats: ALL_FORMATS,
|
||||
source: new UrlSource(src),
|
||||
});
|
||||
|
||||
const [durationInSeconds, format, videoTrack] = await Promise.all([
|
||||
input.computeDuration(),
|
||||
input.getFormat(),
|
||||
input.getPrimaryVideoTrack(),
|
||||
]);
|
||||
|
||||
if (!videoTrack) {
|
||||
throw new Error("No video track found in the input");
|
||||
}
|
||||
|
||||
if (signal?.aborted) {
|
||||
throw new Error("Aborted");
|
||||
}
|
||||
|
||||
const timestamps =
|
||||
typeof timestampsInSeconds === "function"
|
||||
? await timestampsInSeconds({
|
||||
track: {
|
||||
width: videoTrack.displayWidth,
|
||||
height: videoTrack.displayHeight,
|
||||
},
|
||||
container: format.name,
|
||||
durationInSeconds,
|
||||
})
|
||||
: timestampsInSeconds;
|
||||
|
||||
if (timestamps.length === 0) {
|
||||
return;
|
||||
}
|
||||
|
||||
if (signal?.aborted) {
|
||||
throw new Error("Aborted");
|
||||
}
|
||||
|
||||
const sink = new VideoSampleSink(videoTrack);
|
||||
|
||||
for await (using videoSample of sink.samplesAtTimestamps(timestamps)) {
|
||||
if (signal?.aborted) {
|
||||
break;
|
||||
}
|
||||
|
||||
if (!videoSample) {
|
||||
continue;
|
||||
}
|
||||
|
||||
onVideoSample(videoSample);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Basic usage
|
||||
|
||||
Extract frames at specific timestamps:
|
||||
|
||||
```tsx
|
||||
await extractFrames({
|
||||
src: "https://remotion.media/video.mp4",
|
||||
timestampsInSeconds: [0, 1, 2, 3, 4],
|
||||
onVideoSample: (sample) => {
|
||||
const canvas = document.createElement("canvas");
|
||||
canvas.width = sample.displayWidth;
|
||||
canvas.height = sample.displayHeight;
|
||||
const ctx = canvas.getContext("2d");
|
||||
sample.draw(ctx!, 0, 0);
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Creating a filmstrip
|
||||
|
||||
Use a callback function to dynamically calculate timestamps based on video metadata:
|
||||
|
||||
```tsx
|
||||
const canvasWidth = 500;
|
||||
const canvasHeight = 80;
|
||||
const fromSeconds = 0;
|
||||
const toSeconds = 10;
|
||||
|
||||
await extractFrames({
|
||||
src: "https://remotion.media/video.mp4",
|
||||
timestampsInSeconds: async ({ track, durationInSeconds }) => {
|
||||
const aspectRatio = track.width / track.height;
|
||||
const amountOfFramesFit = Math.ceil(
|
||||
canvasWidth / (canvasHeight * aspectRatio)
|
||||
);
|
||||
const segmentDuration = toSeconds - fromSeconds;
|
||||
const timestamps: number[] = [];
|
||||
|
||||
for (let i = 0; i < amountOfFramesFit; i++) {
|
||||
timestamps.push(
|
||||
fromSeconds + (segmentDuration / amountOfFramesFit) * (i + 0.5)
|
||||
);
|
||||
}
|
||||
|
||||
return timestamps;
|
||||
},
|
||||
onVideoSample: (sample) => {
|
||||
console.log(`Frame at ${sample.timestamp}s`);
|
||||
|
||||
const canvas = document.createElement("canvas");
|
||||
canvas.width = sample.displayWidth;
|
||||
canvas.height = sample.displayHeight;
|
||||
const ctx = canvas.getContext("2d");
|
||||
sample.draw(ctx!, 0, 0);
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Cancellation with AbortSignal
|
||||
|
||||
Cancel frame extraction after a timeout:
|
||||
|
||||
```tsx
|
||||
const controller = new AbortController();
|
||||
|
||||
setTimeout(() => controller.abort(), 5000);
|
||||
|
||||
try {
|
||||
await extractFrames({
|
||||
src: "https://remotion.media/video.mp4",
|
||||
timestampsInSeconds: [0, 1, 2, 3, 4],
|
||||
onVideoSample: (sample) => {
|
||||
using frame = sample;
|
||||
const canvas = document.createElement("canvas");
|
||||
canvas.width = frame.displayWidth;
|
||||
canvas.height = frame.displayHeight;
|
||||
const ctx = canvas.getContext("2d");
|
||||
frame.draw(ctx!, 0, 0);
|
||||
},
|
||||
signal: controller.signal,
|
||||
});
|
||||
|
||||
console.log("Frame extraction complete!");
|
||||
} catch (error) {
|
||||
console.error("Frame extraction was aborted or failed:", error);
|
||||
}
|
||||
```
|
||||
|
||||
## Timeout with Promise.race
|
||||
|
||||
```tsx
|
||||
const controller = new AbortController();
|
||||
|
||||
const timeoutPromise = new Promise<never>((_, reject) => {
|
||||
const timeoutId = setTimeout(() => {
|
||||
controller.abort();
|
||||
reject(new Error("Frame extraction timed out after 10 seconds"));
|
||||
}, 10000);
|
||||
|
||||
controller.signal.addEventListener("abort", () => clearTimeout(timeoutId), {
|
||||
once: true,
|
||||
});
|
||||
});
|
||||
|
||||
try {
|
||||
await Promise.race([
|
||||
extractFrames({
|
||||
src: "https://remotion.media/video.mp4",
|
||||
timestampsInSeconds: [0, 1, 2, 3, 4],
|
||||
onVideoSample: (sample) => {
|
||||
using frame = sample;
|
||||
const canvas = document.createElement("canvas");
|
||||
canvas.width = frame.displayWidth;
|
||||
canvas.height = frame.displayHeight;
|
||||
const ctx = canvas.getContext("2d");
|
||||
frame.draw(ctx!, 0, 0);
|
||||
},
|
||||
signal: controller.signal,
|
||||
}),
|
||||
timeoutPromise,
|
||||
]);
|
||||
|
||||
console.log("Frame extraction complete!");
|
||||
} catch (error) {
|
||||
console.error("Frame extraction was aborted or failed:", error);
|
||||
}
|
||||
```

# Using fonts in Remotion
|
||||
|
||||
## Google Fonts with @remotion/google-fonts
|
||||
|
||||
The recommended way to use Google Fonts. It's type-safe and automatically blocks rendering until the font is ready.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
First, the @remotion/google-fonts package needs to be installed.
|
||||
If it is not installed, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/google-fonts # If project uses npm
|
||||
bunx remotion add @remotion/google-fonts # If project uses bun
|
||||
yarn remotion add @remotion/google-fonts # If project uses yarn
|
||||
pnpm exec remotion add @remotion/google-fonts # If project uses pnpm
|
||||
```
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/google-fonts/Lobster";
|
||||
|
||||
const { fontFamily } = loadFont();
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <div style={{ fontFamily }}>Hello World</div>;
|
||||
};
|
||||
```
|
||||
|
||||
Preferrably, specify only needed weights and subsets to reduce file size:
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/google-fonts/Roboto";
|
||||
|
||||
const { fontFamily } = loadFont("normal", {
|
||||
weights: ["400", "700"],
|
||||
subsets: ["latin"],
|
||||
});
|
||||
```
|
||||
|
||||
### Waiting for font to load
|
||||
|
||||
Use `waitUntilDone()` if you need to know when the font is ready:
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/google-fonts/Lobster";
|
||||
|
||||
const { fontFamily, waitUntilDone } = loadFont();
|
||||
|
||||
await waitUntilDone();
|
||||
```
|
||||
|
||||
## Local fonts with @remotion/fonts
|
||||
|
||||
For local font files, use the `@remotion/fonts` package.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
First, install @remotion/fonts:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/fonts # If project uses npm
|
||||
bunx remotion add @remotion/fonts # If project uses bun
|
||||
yarn remotion add @remotion/fonts # If project uses yarn
|
||||
pnpm exec remotion add @remotion/fonts # If project uses pnpm
|
||||
```
|
||||
|
||||
### Loading a local font
|
||||
|
||||
Place your font file in the `public/` folder and use `loadFont()`:
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/fonts";
|
||||
import { staticFile } from "remotion";
|
||||
|
||||
await loadFont({
|
||||
family: "MyFont",
|
||||
url: staticFile("MyFont-Regular.woff2"),
|
||||
});
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <div style={{ fontFamily: "MyFont" }}>Hello World</div>;
|
||||
};
|
||||
```
|
||||
|
||||
### Loading multiple weights
|
||||
|
||||
Load each weight separately with the same family name:
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/fonts";
|
||||
import { staticFile } from "remotion";
|
||||
|
||||
await Promise.all([
|
||||
loadFont({
|
||||
family: "Inter",
|
||||
url: staticFile("Inter-Regular.woff2"),
|
||||
weight: "400",
|
||||
}),
|
||||
loadFont({
|
||||
family: "Inter",
|
||||
url: staticFile("Inter-Bold.woff2"),
|
||||
weight: "700",
|
||||
}),
|
||||
]);
|
||||
```
|
||||
|
||||
### Available options
|
||||
|
||||
```tsx
|
||||
loadFont({
|
||||
family: "MyFont", // Required: name to use in CSS
|
||||
url: staticFile("font.woff2"), // Required: font file URL
|
||||
format: "woff2", // Optional: auto-detected from extension
|
||||
weight: "400", // Optional: font weight
|
||||
style: "normal", // Optional: normal or italic
|
||||
display: "block", // Optional: font-display behavior
|
||||
});
|
||||
```
|
||||
|
||||
## Using in components
|
||||
|
||||
Call `loadFont()` at the top level of your component or in a separate file that's imported early:
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/google-fonts/Montserrat";
|
||||
|
||||
const { fontFamily } = loadFont("normal", {
|
||||
weights: ["400", "700"],
|
||||
subsets: ["latin"],
|
||||
});
|
||||
|
||||
export const Title: React.FC<{ text: string }> = ({ text }) => {
|
||||
return (
|
||||
<h1
|
||||
style={{
|
||||
fontFamily,
|
||||
fontSize: 80,
|
||||
fontWeight: "bold",
|
||||
}}
|
||||
>
|
||||
{text}
|
||||
</h1>
|
||||
);
|
||||
};
|
||||
```

# Getting audio duration with Mediabunny
|
||||
|
||||
Mediabunny can extract the duration of an audio file. It works in browser, Node.js, and Bun environments.
|
||||
|
||||
## Getting audio duration
|
||||
|
||||
```tsx
|
||||
import { Input, ALL_FORMATS, UrlSource } from "mediabunny";
|
||||
|
||||
export const getAudioDuration = async (src: string) => {
|
||||
const input = new Input({
|
||||
formats: ALL_FORMATS,
|
||||
source: new UrlSource(src, {
|
||||
getRetryDelay: () => null,
|
||||
}),
|
||||
});
|
||||
|
||||
const durationInSeconds = await input.computeDuration();
|
||||
return durationInSeconds;
|
||||
};
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```tsx
|
||||
const duration = await getAudioDuration("https://remotion.media/audio.mp3");
|
||||
console.log(duration); // e.g. 180.5 (seconds)
|
||||
```
|
||||
|
||||
## Using with local files
|
||||
|
||||
For local files, use `FileSource` instead of `UrlSource`:
|
||||
|
||||
```tsx
|
||||
import { Input, ALL_FORMATS, FileSource } from "mediabunny";
|
||||
|
||||
const input = new Input({
|
||||
formats: ALL_FORMATS,
|
||||
source: new FileSource(file), // File object from input or drag-drop
|
||||
});
|
||||
|
||||
const durationInSeconds = await input.computeDuration();
|
||||
```
|
||||
|
||||
## Using with staticFile in Remotion
|
||||
|
||||
```tsx
|
||||
import { staticFile } from "remotion";
|
||||

# Using Animated images in Remotion
|
||||
|
||||
## Basic usage
|
||||
|
||||
Use `<AnimatedImage>` to display a GIF, APNG, AVIF or WebP image synchronized with Remotion's timeline:
|
||||
|
||||
```tsx
|
||||
import {AnimatedImage, staticFile} from 'remotion';
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <AnimatedImage src={staticFile('animation.gif')} width={500} height={500} />;
|
||||
};
|
||||
```
|
||||
|
||||
Remote URLs are also supported (must have CORS enabled):
|
||||
|
||||
```tsx
|
||||
<AnimatedImage src="https://example.com/animation.gif" width={500} height={500} />
|
||||
```
|
||||
|
||||
## Sizing and fit
|
||||
|
||||
Control how the image fills its container with the `fit` prop:
|
||||
|
||||
```tsx
|
||||
// Stretch to fill (default)
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="fill" />
|
||||
|
||||
// Maintain aspect ratio, fit inside container
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="contain" />
|
||||
|
||||
// Fill container, crop if needed
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="cover" />
|
||||
```
|
||||
|
||||
## Playback speed
|
||||
|
||||
Use `playbackRate` to control the animation speed:
|
||||
|
||||
```tsx
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} playbackRate={2} /> {/* 2x speed */}
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} playbackRate={0.5} /> {/* Half speed */}
|
||||
```
|
||||
|
||||
## Looping behavior
|
||||
|
||||
Control what happens when the animation finishes:
|
||||
|
||||
```tsx
|
||||
// Loop indefinitely (default)
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="loop" />
|
||||
|
||||
// Play once, show final frame
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="pause-after-finish" />
|
||||
|
||||
// Play once, then clear canvas
|
||||
<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="clear-after-finish" />
|
||||
```
|
||||
|
||||
## Styling
|
||||
|
||||
Use the `style` prop for additional CSS (use `width` and `height` props for sizing):
|
||||
|
||||
```tsx
|
||||
<AnimatedImage
|
||||
src={staticFile('animation.gif')}
|
||||
width={500}
|
||||
height={500}
|
||||
style={{
|
||||
borderRadius: 20,
|
||||
position: 'absolute',
|
||||
top: 100,
|
||||
left: 50,
|
||||
}}
|
||||
/>
|
||||
```
|
||||
|
||||
## Getting GIF duration
|
||||
|
||||
Use `getGifDurationInSeconds()` from `@remotion/gif` to get the duration of a GIF.
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/gif # If project uses npm
|
||||
bunx remotion add @remotion/gif # If project uses bun
|
||||
yarn remotion add @remotion/gif # If project uses yarn
|
||||
pnpm exec remotion add @remotion/gif # If project uses pnpm
|
||||
```
|
||||
|
||||
```tsx
|
||||
import {getGifDurationInSeconds} from '@remotion/gif';
|
||||
import {staticFile} from 'remotion';
|
||||
|
||||
const duration = await getGifDurationInSeconds(staticFile('animation.gif'));
|
||||
console.log(duration); // e.g. 2.5
|
||||
```
|
||||
|
||||
This is useful for setting the composition duration to match the GIF:
|
||||
|
||||
```tsx
|
||||
import {getGifDurationInSeconds} from '@remotion/gif';
|
||||
import {staticFile, CalculateMetadataFunction} from 'remotion';
|
||||
|
||||
const calculateMetadata: CalculateMetadataFunction = async () => {
|
||||
const duration = await getGifDurationInSeconds(staticFile('animation.gif'));
|
||||
return {
|
||||
durationInFrames: Math.ceil(duration * 30),
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
## Alternative
|
||||
|
||||
If `<AnimatedImage>` does not work (only supported in Chrome and Firefox), you can use `<Gif>` from `@remotion/gif` instead.
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/gif # If project uses npm
|
||||
bunx remotion add @remotion/gif # If project uses bun
|
||||
yarn remotion add @remotion/gif # If project uses yarn
|
||||
pnpm exec remotion add @remotion/gif # If project uses pnpm
|
||||
```
|
||||
|
||||
```tsx
|
||||
import {Gif} from '@remotion/gif';
|
||||
import {staticFile} from 'remotion';
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <Gif src={staticFile('animation.gif')} width={500} height={500} />;
|
||||
};
|
||||
```
|
||||
|
||||
The `<Gif>` component has the same props as `<AnimatedImage>` but only supports GIF files.

# Using images in Remotion
|
||||
|
||||
## The `<Img>` component
|
||||
|
||||
Always use the `<Img>` component from `remotion` to display images:
|
||||
|
||||
```tsx
|
||||
import { Img, staticFile } from "remotion";
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <Img src={staticFile("photo.png")} />;
|
||||
};
|
||||
```
|
||||
|
||||
## Important restrictions
|
||||
|
||||
**You MUST use the `<Img>` component from `remotion`.** Do not use:
|
||||
|
||||
- Native HTML `<img>` elements
|
||||
- Next.js `<Image>` component
|
||||
- CSS `background-image`
|
||||
|
||||
The `<Img>` component ensures images are fully loaded before rendering, preventing flickering and blank frames during video export.
|
||||
|
||||
## Local images with staticFile()
|
||||
|
||||
Place images in the `public/` folder and use `staticFile()` to reference them:
|
||||
|
||||
```
|
||||
my-video/
|
||||
├─ public/
|
||||
│ ├─ logo.png
|
||||
│ ├─ avatar.jpg
|
||||
│ └─ icon.svg
|
||||
├─ src/
|
||||
├─ package.json
|
||||
```
|
||||
|
||||
```tsx
|
||||
import { Img, staticFile } from "remotion";
|
||||
|
||||
<Img src={staticFile("logo.png")} />
|
||||
```
|
||||
|
||||
## Remote images
|
||||
|
||||
Remote URLs can be used directly without `staticFile()`:
|
||||
|
||||
```tsx
|
||||
<Img src="https://example.com/image.png" />
|
||||
```
|
||||
|
||||
Ensure remote images have CORS enabled.
|
||||
|
||||
For animated GIFs, use the `<Gif>` component from `@remotion/gif` instead.
|
||||
|
||||
## Sizing and positioning
|
||||
|
||||
Use the `style` prop to control size and position:
|
||||
|
||||
```tsx
|
||||
<Img
|
||||
src={staticFile("photo.png")}
|
||||
style={{
|
||||
width: 500,
|
||||
height: 300,
|
||||
position: "absolute",
|
||||
top: 100,
|
||||
left: 50,
|
||||
objectFit: "cover",
|
||||
}}
|
||||
/>
|
||||
```
|
||||
|
||||
## Dynamic image paths
|
||||
|
||||
Use template literals for dynamic file references:
|
||||
|
||||
```tsx
|
||||
import { Img, staticFile, useCurrentFrame } from "remotion";
|
||||
|
||||
const frame = useCurrentFrame();
|
||||
|
||||
// Image sequence
|
||||
<Img src={staticFile(`frames/frame${frame}.png`)} />
|
||||
|
||||
// Selecting based on props
|
||||
<Img src={staticFile(`avatars/${props.userId}.png`)} />
|
||||
|
||||
// Conditional images
|
||||
<Img src={staticFile(`icons/${isActive ? "active" : "inactive"}.svg`)} />
|
||||
```
|
||||
|
||||
This pattern is useful for:
|
||||
|
||||
- Image sequences (frame-by-frame animations)
|
||||
- User-specific avatars or profile images
|
||||
- Theme-based icons
|
||||
- State-dependent graphics
|
||||
|
||||
## Getting image dimensions
|
||||
|
||||
Use `getImageDimensions()` to get the dimensions of an image:
|
||||
|
||||
```tsx
|
||||
import { getImageDimensions, staticFile } from "remotion";
|
||||
|
||||
const { width, height } = await getImageDimensions(staticFile("photo.png"));
|
||||
```
|
||||
|
||||
This is useful for calculating aspect ratios or sizing compositions:
|
||||
|
||||
```tsx
|
||||
import { getImageDimensions, staticFile, CalculateMetadataFunction } from "remotion";
|
||||
|
||||
const calculateMetadata: CalculateMetadataFunction = async () => {
|
||||
const { width, height } = await getImageDimensions(staticFile("photo.png"));
|
||||
return {
|
||||
width,
|
||||
height,
|
||||
};
|
||||
};
|
||||
```

# Importing .srt subtitles into Remotion
|
||||
|
||||
If you have an existing `.srt` subtitle file, you can import it into Remotion using `parseSrt()` from `@remotion/captions`.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/captions package needs to be installed.
|
||||
If it is not installed, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/captions # If project uses npm
|
||||
bunx remotion add @remotion/captions # If project uses bun
|
||||
yarn remotion add @remotion/captions # If project uses yarn
|
||||
pnpm exec remotion add @remotion/captions # If project uses pnpm
|
||||
```
|
||||
|
||||
## Reading an .srt file
|
||||
|
||||
Use `staticFile()` to reference an `.srt` file in your `public` folder, then fetch and parse it:
|
||||
|
||||
```tsx
|
||||
import {useState, useEffect, useCallback} from 'react';
|
||||
import {AbsoluteFill, staticFile, useDelayRender} from 'remotion';
|
||||
import {parseSrt} from '@remotion/captions';
|
||||
import type {Caption} from '@remotion/captions';
|
||||
|
||||
export const MyComponent: React.FC = () => {
|
||||
const [captions, setCaptions] = useState<Caption[] | null>(null);
|
||||
const {delayRender, continueRender, cancelRender} = useDelayRender();
|
||||
const [handle] = useState(() => delayRender());
|
||||
|
||||
const fetchCaptions = useCallback(async () => {
|
||||
try {
|
||||
const response = await fetch(staticFile('subtitles.srt'));
|
||||
const text = await response.text();
|
||||
const {captions: parsed} = parseSrt({input: text});
|
||||
setCaptions(parsed);
|
||||
continueRender(handle);
|
||||
} catch (e) {
|
||||
cancelRender(e);
|
||||
}
|
||||
}, [continueRender, cancelRender, handle]);
|
||||
|
||||
useEffect(() => {
|
||||
fetchCaptions();
|
||||
}, [fetchCaptions]);
|
||||
|
||||
if (!captions) {
|
||||
return null;
|
||||
}
|
||||
|
||||
return <AbsoluteFill>{/* Use captions here */}</AbsoluteFill>;
|
||||
};
|
||||
```
|
||||
|
||||
Remote URLs are also supported - you can `fetch()` a remote file via URL instead of using `staticFile()`.
|
||||
|
||||
## Using imported captions
|
||||
|
||||
Once parsed, the captions are in the `Caption` format and can be used with all `@remotion/captions` utilities.

# Using Lottie Animations in Remotion
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/lottie package needs to be installed.
|
||||
If it is not, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/lottie # If project uses npm
|
||||
bunx remotion add @remotion/lottie # If project uses bun
|
||||
yarn remotion add @remotion/lottie # If project uses yarn
|
||||
pnpm exec remotion add @remotion/lottie # If project uses pnpm
|
||||
```
|
||||
|
||||
## Displaying a Lottie file
|
||||
|
||||
To import a Lottie animation:
|
||||
|
||||
- Fetch the Lottie asset
|
||||
- Wrap the loading process in `delayRender()` and `continueRender()`
|
||||
- Save the animation data in a state
|
||||
- Render the Lottie animation using the `Lottie` component from the `@remotion/lottie` package
|
||||
|
||||
```tsx
|
||||
import {Lottie, LottieAnimationData} from '@remotion/lottie';
|
||||
import {useEffect, useState} from 'react';
|
||||
import {cancelRender, continueRender, delayRender} from 'remotion';
|
||||
|
||||
export const MyAnimation = () => {
|
||||
const [handle] = useState(() => delayRender('Loading Lottie animation'));
|
||||
|
||||
const [animationData, setAnimationData] = useState<LottieAnimationData | null>(null);
|
||||
|
||||
useEffect(() => {
|
||||
fetch('https://assets4.lottiefiles.com/packages/lf20_zyquagfl.json')
|
||||
.then((data) => data.json())
|
||||
.then((json) => {
|
||||
setAnimationData(json);
|
||||
continueRender(handle);
|
||||
})
|
||||
.catch((err) => {
|
||||
cancelRender(err);
|
||||
});
|
||||
}, [handle]);
|
||||
|
||||
if (!animationData) {
|
||||
return null;
|
||||
}
|
||||
|
||||
return <Lottie animationData={animationData} />;
|
||||
};
|
||||
```
|
||||
|
||||
## Styling and animating
|
||||
|
||||
Lottie supports the `style` prop to allow styles and animations:
|
||||
|
||||
```tsx
|
||||
return <Lottie animationData={animationData} style={{width: 400, height: 400}} />;
|
||||
```

# Measuring DOM nodes in Remotion
|
||||
|
||||
Remotion applies a `scale()` transform to the video container, which affects values from `getBoundingClientRect()`. Use `useCurrentScale()` to get correct measurements.
|
||||
|
||||
## Measuring element dimensions
|
||||
|
||||
```tsx
|
||||
import { useCurrentScale } from "remotion";
|
||||
import { useRef, useEffect, useState } from "react";
|
||||
|
||||
export const MyComponent = () => {
|
||||
const ref = useRef<HTMLDivElement>(null);
|
||||
const scale = useCurrentScale();
|
||||
const [dimensions, setDimensions] = useState({ width: 0, height: 0 });
|
||||
|
||||
useEffect(() => {
|
||||
if (!ref.current) return;
|
||||
const rect = ref.current.getBoundingClientRect();
|
||||
setDimensions({
|
||||
width: rect.width / scale,
|
||||
height: rect.height / scale,
|
||||
});
|
||||
}, [scale]);
|
||||
|
||||
return <div ref={ref}>Content to measure</div>;
|
||||
};
|
||||
```

# Measuring text in Remotion
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Install @remotion/layout-utils if it is not already installed:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/layout-utils # If project uses npm
|
||||
bunx remotion add @remotion/layout-utils # If project uses bun
|
||||
yarn remotion add @remotion/layout-utils # If project uses yarn
|
||||
pnpm exec remotion add @remotion/layout-utils # If project uses pnpm
|
||||
```
|
||||
|
||||
## Measuring text dimensions
|
||||
|
||||
Use `measureText()` to calculate the width and height of text:
|
||||
|
||||
```tsx
|
||||
import { measureText } from "@remotion/layout-utils";
|
||||
|
||||
const { width, height } = measureText({
|
||||
text: "Hello World",
|
||||
fontFamily: "Arial",
|
||||
fontSize: 32,
|
||||
fontWeight: "bold",
|
||||
});
|
||||
```
|
||||
|
||||
Results are cached - duplicate calls return the cached result.
|
||||
|
||||
## Fitting text to a width
|
||||
|
||||
Use `fitText()` to find the optimal font size for a container:
|
||||
|
||||
```tsx
|
||||
import { fitText } from "@remotion/layout-utils";
|
||||
|
||||
const { fontSize } = fitText({
|
||||
text: "Hello World",
|
||||
withinWidth: 600,
|
||||
fontFamily: "Inter",
|
||||
fontWeight: "bold",
|
||||
});
|
||||
|
||||
return (
|
||||
<div
|
||||
style={{
|
||||
fontSize: Math.min(fontSize, 80), // Cap at 80px
|
||||
fontFamily: "Inter",
|
||||
fontWeight: "bold",
|
||||
}}
|
||||
>
|
||||
Hello World
|
||||
</div>
|
||||
);
|
||||
```
|
||||
|
||||
## Checking text overflow
|
||||
|
||||
Use `fillTextBox()` to check if text exceeds a box:
|
||||
|
||||
```tsx
|
||||
import { fillTextBox } from "@remotion/layout-utils";
|
||||
|
||||
const box = fillTextBox({ maxBoxWidth: 400, maxLines: 3 });
|
||||
|
||||
const words = ["Hello", "World", "This", "is", "a", "test"];
|
||||
for (const word of words) {
|
||||
const { exceedsBox } = box.add({
|
||||
text: word + " ",
|
||||
fontFamily: "Arial",
|
||||
fontSize: 24,
|
||||
});
|
||||
if (exceedsBox) {
|
||||
// Text would overflow, handle accordingly
|
||||
break;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Best practices
|
||||
|
||||
**Load fonts first:** Only call measurement functions after fonts are loaded.
|
||||
|
||||
```tsx
|
||||
import { loadFont } from "@remotion/google-fonts/Inter";
|
||||
|
||||
const { fontFamily, waitUntilDone } = loadFont("normal", {
|
||||
weights: ["400"],
|
||||
subsets: ["latin"],
|
||||
});
|
||||
|
||||
waitUntilDone().then(() => {
|
||||
// Now safe to measure
|
||||
const { width } = measureText({
|
||||
text: "Hello",
|
||||
fontFamily,
|
||||
fontSize: 32,
|
||||
});
|
||||
})
|
||||
```
|
||||
|
||||
**Use validateFontIsLoaded:** Catch font loading issues early:
|
||||
|
||||
```tsx
|
||||
measureText({
|
||||
text: "Hello",
|
||||
fontFamily: "MyCustomFont",
|
||||
fontSize: 32,
|
||||
validateFontIsLoaded: true, // Throws if font not loaded
|
||||
});
|
||||
```
|
||||
|
||||
**Match font properties:** Use the same properties for measurement and rendering:
|
||||
|
||||
```tsx
|
||||
const fontStyle = {
|
||||
fontFamily: "Inter",
|
||||
fontSize: 32,
|
||||
fontWeight: "bold" as const,
|
||||
letterSpacing: "0.5px",
|
||||
};
|
||||
|
||||
const { width } = measureText({
|
||||
text: "Hello",
|
||||
...fontStyle,
|
||||
});
|
||||
|
||||
return <div style={fontStyle}>Hello</div>;
|
||||
```
|
||||
|
||||
**Avoid padding and border:** Use `outline` instead of `border` to prevent layout differences:
|
||||
|
||||
```tsx
|
||||
<div style={{ outline: "2px solid red" }}>Text</div>
|
||||
```

tags: sequence, series, timing, delay, trim
|
||||
---
|
||||
|
||||
Use `<Sequence>` to delay when an element appears in the timeline.
|
||||
|
||||
```tsx
|
||||
import { Sequence } from "remotion";
|
||||
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
<Sequence from={1 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
|
||||
<Title />
|
||||
</Sequence>
|
||||
<Sequence from={2 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
|
||||
<Subtitle />
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
This will by default wrap the component in an absolute fill element.
|
||||
If the items should not be wrapped, use the `layout` prop:
|
||||
|
||||
```tsx
|
||||
<Sequence layout="none">
|
||||
<Title />
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
## Premounting
|
||||
|
||||
This loads the component in the timeline before it is actually played.
|
||||
Always premount any `<Sequence>`!
|
||||
|
||||
```tsx
|
||||
<Sequence premountFor={1 * fps}>
|
||||
<Title />
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
## Series
|
||||
|
||||
Use `<Series>` when elements should play one after another without overlap.
|
||||
|
||||
```tsx
|
||||
import {Series} from 'remotion';
|
||||
|
||||
<Series>
|
||||
<Series.Sequence durationInFrames={45}>
|
||||
<Intro />
|
||||
</Series.Sequence>
|
||||
<Series.Sequence durationInFrames={60}>
|
||||
<MainContent />
|
||||
</Series.Sequence>
|
||||
<Series.Sequence durationInFrames={30}>
|
||||
<Outro />
|
||||
</Series.Sequence>
|
||||
</Series>;
|
||||
```
|
||||
|
||||
Same as with `<Sequence>`, the items will be wrapped in an absolute fill element by default when using `<Series.Sequence>`, unless the `layout` prop is set to `none`.
|
||||
|
||||
### Series with overlaps
|
||||
|
||||
Use negative offset for overlapping sequences:
|
||||
|
||||
```tsx
|
||||
<Series>
|
||||
<Series.Sequence durationInFrames={60}>
|
||||
<SceneA />
|
||||
</Series.Sequence>
|
||||
<Series.Sequence offset={-15} durationInFrames={60}>
|
||||
{/* Starts 15 frames before SceneA ends */}
|
||||
<SceneB />
|
||||
</Series.Sequence>
|
||||
</Series>
|
||||
```
|
||||
|
||||
## Frame References Inside Sequences
|
||||
|
||||
Inside a Sequence, `useCurrentFrame()` returns the local frame (starting from 0):
|
||||
|
||||
```tsx
|
||||
<Sequence from={60} durationInFrames={30}>
|
||||
<MyComponent />
|
||||
{/* Inside MyComponent, useCurrentFrame() returns 0-29, not 60-89 */}
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
## Nested Sequences
|
||||
|
||||
Sequences can be nested for complex timing:
|
||||
|
||||
```tsx
|
||||
<Sequence from={0} durationInFrames={120}>
|
||||
<Background />
|
||||
<Sequence from={15} durationInFrames={90} layout="none">
|
||||
<Title />
|
||||
</Sequence>
|
||||
<Sequence from={45} durationInFrames={60} layout="none">
|
||||
<Subtitle />
|
||||
</Sequence>
|
||||
</Sequence>
|
||||
```

You can and should use TailwindCSS in Remotion, if TailwindCSS is installed in the project.
|
||||
|
||||
Don't use `transition-*` or `animate-*` classes - always animate using the `useCurrentFrame()` hook.
|
||||
|
||||
Tailwind must be installed and enabled first in a Remotion project - fetch https://www.remotion.dev/docs/tailwind using WebFetch for instructions.

## Text animations
|
||||
|
||||
Based on `useCurrentFrame()`, reduce the string character by character to create a typewriter effect.
|
||||
|
||||
## Typewriter Effect
|
||||
|
||||
See [Typewriter](assets/text-animations-typewriter.tsx) for an advanced example with a blinking cursor and a pause after the first sentence.
|
||||
|
||||
Always use string slicing for typewriter effects. Never use per-character opacity.
|
||||
|
||||
## Word Highlighting
|
||||
|
||||
See [Word Highlight](assets/text-animations-word-highlight.tsx) for an example for how a word highlight is animated, like with a highlighter pen.

description: Interpolation curves in Remotion - linear, easing, spring animations
|
||||
metadata:
|
||||
tags: spring, bounce, easing, interpolation
|
||||
---
|
||||
|
||||
A simple linear interpolation is done using the `interpolate` function.
|
||||
|
||||
```ts title="Going from 0 to 1 over 100 frames"
|
||||
import {interpolate} from 'remotion';
|
||||
|
||||
const opacity = interpolate(frame, [0, 100], [0, 1]);
|
||||
```
|
||||
|
||||
By default, the values are not clamped, so the value can go outside the range [0, 1].
|
||||
Here is how they can be clamped:
|
||||
|
||||
```ts title="Going from 0 to 1 over 100 frames with extrapolation"
|
||||
const opacity = interpolate(frame, [0, 100], [0, 1], {
|
||||
extrapolateRight: 'clamp',
|
||||
extrapolateLeft: 'clamp',
|
||||
});
|
||||
```
|
||||
|
||||
## Spring animations
|
||||
|
||||
Spring animations have a more natural motion.
|
||||
They go from 0 to 1 over time.
|
||||
|
||||
```ts title="Spring animation from 0 to 1 over 100 frames"
|
||||
import {spring, useCurrentFrame, useVideoConfig} from 'remotion';
|
||||
|
||||
const frame = useCurrentFrame();
|
||||
const {fps} = useVideoConfig();
|
||||
|
||||
const scale = spring({
|
||||
frame,
|
||||
fps,
|
||||
});
|
||||
```
|
||||
|
||||
### Physical properties
|
||||
|
||||
The default configuration is: `mass: 1, damping: 10, stiffness: 100`.
|
||||
This leads to the animation having a bit of bounce before it settles.
|
||||
|
||||
The config can be overwritten like this:
|
||||
|
||||
```ts
|
||||
const scale = spring({
|
||||
frame,
|
||||
fps,
|
||||
config: {damping: 200},
|
||||
});
|
||||
```
|
||||
|
||||
The recommended configuration for a natural motion without a bounce is: `{ damping: 200 }`.
|
||||
|
||||
Here are some common configurations:
|
||||
|
||||
```tsx
|
||||
const smooth = {damping: 200}; // Smooth, no bounce (subtle reveals)
|
||||
const snappy = {damping: 20, stiffness: 200}; // Snappy, minimal bounce (UI elements)
|
||||
const bouncy = {damping: 8}; // Bouncy entrance (playful animations)
|
||||
const heavy = {damping: 15, stiffness: 80, mass: 2}; // Heavy, slow, small bounce
|
||||
```
|
||||
|
||||
### Delay
|
||||
|
||||
The animation starts immediately by default.
|
||||
Use the `delay` parameter to delay the animation by a number of frames.
|
||||
|
||||
```tsx
|
||||
const entrance = spring({
|
||||
frame: frame - ENTRANCE_DELAY,
|
||||
fps,
|
||||
delay: 20,
|
||||
});
|
||||
```
|
||||
|
||||
### Duration
|
||||
|
||||
A `spring()` has a natural duration based on the physical properties.
|
||||
To stretch the animation to a specific duration, use the `durationInFrames` parameter.
|
||||
|
||||
```tsx
|
||||
const spring = spring({
|
||||
frame,
|
||||
fps,
|
||||
durationInFrames: 40,
|
||||
});
|
||||
```
|
||||
|
||||
### Combining spring() with interpolate()
|
||||
|
||||
Map spring output (0-1) to custom ranges:
|
||||
|
||||
```tsx
|
||||
const springProgress = spring({
|
||||
frame,
|
||||
fps,
|
||||
});
|
||||
|
||||
// Map to rotation
|
||||
const rotation = interpolate(springProgress, [0, 1], [0, 360]);
|
||||
|
||||
<div style={{rotate: rotation + 'deg'}} />;
|
||||
```
|
||||
|
||||
### Adding springs
|
||||
|
||||
Springs return just numbers, so math can be performed:
|
||||
|
||||
```tsx
|
||||
const frame = useCurrentFrame();
|
||||
const {fps, durationInFrames} = useVideoConfig();
|
||||
|
||||
const inAnimation = spring({
|
||||
frame,
|
||||
fps,
|
||||
});
|
||||
const outAnimation = spring({
|
||||
frame,
|
||||
fps,
|
||||
durationInFrames: 1 * fps,
|
||||
delay: durationInFrames - 1 * fps,
|
||||
});
|
||||
|
||||
const scale = inAnimation - outAnimation;
|
||||
```
|
||||
|
||||
## Easing
|
||||
|
||||
Easing can be added to the `interpolate` function:
|
||||
|
||||
```ts
|
||||
import {interpolate, Easing} from 'remotion';
|
||||
|
||||
const value1 = interpolate(frame, [0, 100], [0, 1], {
|
||||
easing: Easing.inOut(Easing.quad),
|
||||
extrapolateLeft: 'clamp',
|
||||
extrapolateRight: 'clamp',
|
||||
});
|
||||
```
|
||||
|
||||
The default easing is `Easing.linear`.
|
||||
There are various other convexities:
|
||||
|
||||
- `Easing.in` for starting slow and accelerating
|
||||
- `Easing.out` for starting fast and slowing down
|
||||
- `Easing.inOut`
|
||||
|
||||
and curves (sorted from most linear to most curved):
|
||||
|
||||
- `Easing.quad`
|
||||
- `Easing.sin`
|
||||
- `Easing.exp`
|
||||
- `Easing.circle`
|
||||
|
||||
Convexities and curves need be combined for an easing function:
|
||||
|
||||
```ts
|
||||
const value1 = interpolate(frame, [0, 100], [0, 1], {
|
||||
easing: Easing.inOut(Easing.quad),
|
||||
extrapolateLeft: 'clamp',
|
||||
extrapolateRight: 'clamp',
|
||||
});
|
||||
```
|
||||
|
||||
Cubic bezier curves are also supported:
|
||||
|
||||
```ts
|
||||
const value1 = interpolate(frame, [0, 100], [0, 1], {
|
||||
easing: Easing.bezier(0.8, 0.22, 0.96, 0.65),
|
||||
extrapolateLeft: 'clamp',
|
||||
extrapolateRight: 'clamp',
|
||||
});
|
||||
```

# Transcribing audio
|
||||
|
||||
Remotion provides several built-in options for transcribing audio to generate captions:
|
||||
|
||||
- `@remotion/install-whisper-cpp` - Transcribe locally on a server using Whisper.cpp. Fast and free, but requires server infrastructure.
|
||||
https://remotion.dev/docs/install-whisper-cpp
|
||||
|
||||
- `@remotion/whisper-web` - Transcribe in the browser using WebAssembly. No server needed and free, but slower due to WASM overhead.
|
||||
https://remotion.dev/docs/whisper-web
|
||||
|
||||
- `@remotion/openai-whisper` - Use OpenAI Whisper API for cloud-based transcription. Fast and no server needed, but requires payment.
|
||||

|

|
||||
## Fullscreen transitions
|
||||
|
||||
Using `<TransitionSeries>` to animate between multiple scenes or clips.
|
||||
This will absolutely position the children.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/transitions package needs to be installed.
|
||||
If it is not, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/transitions # If project uses npm
|
||||
bunx remotion add @remotion/transitions # If project uses bun
|
||||
yarn remotion add @remotion/transitions # If project uses yarn
|
||||
pnpm exec remotion add @remotion/transitions # If project uses pnpm
|
||||
```
|
||||
|
||||
## Example usage
|
||||
|
||||
```tsx
|
||||
import {TransitionSeries, linearTiming} from '@remotion/transitions';
|
||||
import {fade} from '@remotion/transitions/fade';
|
||||
|
||||
<TransitionSeries>
|
||||
<TransitionSeries.Sequence durationInFrames={60}>
|
||||
<SceneA />
|
||||
</TransitionSeries.Sequence>
|
||||
<TransitionSeries.Transition presentation={fade()} timing={linearTiming({durationInFrames: 15})} />
|
||||
<TransitionSeries.Sequence durationInFrames={60}>
|
||||
<SceneB />
|
||||
</TransitionSeries.Sequence>
|
||||
</TransitionSeries>;
|
||||
```
|
||||
|
||||
## Available Transition Types
|
||||
|
||||
Import transitions from their respective modules:
|
||||
|
||||
```tsx
|
||||
import {fade} from '@remotion/transitions/fade';
|
||||
import {slide} from '@remotion/transitions/slide';
|
||||
import {wipe} from '@remotion/transitions/wipe';
|
||||
import {flip} from '@remotion/transitions/flip';
|
||||
import {clockWipe} from '@remotion/transitions/clock-wipe';
|
||||
```
|
||||
|
||||
## Slide Transition with Direction
|
||||
|
||||
Specify slide direction for enter/exit animations.
|
||||
|
||||
```tsx
|
||||
import {slide} from '@remotion/transitions/slide';
|
||||
|
||||
<TransitionSeries.Transition presentation={slide({direction: 'from-left'})} timing={linearTiming({durationInFrames: 20})} />;
|
||||
```
|
||||
|
||||
Directions: `"from-left"`, `"from-right"`, `"from-top"`, `"from-bottom"`
|
||||
|
||||
## Timing Options
|
||||
|
||||
```tsx
|
||||
import {linearTiming, springTiming} from '@remotion/transitions';
|
||||
|
||||
// Linear timing - constant speed
|
||||
linearTiming({durationInFrames: 20});
|
||||
|
||||
// Spring timing - organic motion
|
||||
springTiming({config: {damping: 200}, durationInFrames: 25});
|
||||
```
|
||||
|
||||
## Duration calculation
|
||||
|
||||
Transitions overlap adjacent scenes, so the total composition length is **shorter** than the sum of all sequence durations.
|
||||
|
||||
For example, with two 60-frame sequences and a 15-frame transition:
|
||||
|
||||
- Without transitions: `60 + 60 = 120` frames
|
||||
- With transition: `60 + 60 - 15 = 105` frames
|
||||
|
||||
The transition duration is subtracted because both scenes play simultaneously during the transition.
|
||||
|
||||
### Getting the duration of a transition
|
||||
|
||||
Use the `getDurationInFrames()` method on the timing object:
|
||||
|
||||
```tsx
|
||||
import {linearTiming, springTiming} from '@remotion/transitions';
|
||||
|
||||
const linearDuration = linearTiming({durationInFrames: 20}).getDurationInFrames({fps: 30});
|
||||
// Returns 20
|
||||
|
||||
const springDuration = springTiming({config: {damping: 200}}).getDurationInFrames({fps: 30});
|
||||
// Returns calculated duration based on spring physics
|
||||
```
|
||||
|
||||
For `springTiming` without an explicit `durationInFrames`, the duration depends on `fps` because it calculates when the spring animation settles.
|
||||
|
||||
### Calculating total composition duration
|
||||
|
||||
```tsx
|
||||
import {linearTiming} from '@remotion/transitions';
|
||||
|
||||
const scene1Duration = 60;
|
||||
const scene2Duration = 60;
|
||||
const scene3Duration = 60;
|
||||
|
||||
const timing1 = linearTiming({durationInFrames: 15});
|
||||
const timing2 = linearTiming({durationInFrames: 20});
|
||||
|
||||
const transition1Duration = timing1.getDurationInFrames({fps: 30});
|
||||
const transition2Duration = timing2.getDurationInFrames({fps: 30});
|
||||
|
||||
const totalDuration = scene1Duration + scene2Duration + scene3Duration - transition1Duration - transition2Duration;
|
||||
// 60 + 60 + 60 - 15 - 20 = 145 frames
|
||||
```

|
||||
---
|
||||
|
||||
Use `<Sequence>` with a negative `from` value to trim the start of an animation.
|
||||
|
||||
## Trim the Beginning
|
||||
|
||||
A negative `from` value shifts time backwards, making the animation start partway through:
|
||||
|
||||
```tsx
|
||||
import { Sequence, useVideoConfig } from "remotion";
|
||||
|
||||
const fps = useVideoConfig();
|
||||
|
||||
<Sequence from={-0.5 * fps}>
|
||||
<MyAnimation />
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
The animation appears 15 frames into its progress - the first 15 frames are trimmed off.
|
||||
Inside `<MyAnimation>`, `useCurrentFrame()` starts at 15 instead of 0.
|
||||
|
||||
## Trim the End
|
||||
|
||||
Use `durationInFrames` to unmount content after a specified duration:
|
||||
|
||||
```tsx
|
||||
|
||||
<Sequence durationInFrames={1.5 * fps}>
|
||||
<MyAnimation />
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
The animation plays for 45 frames, then the component unmounts.
|
||||
|
||||
## Trim and Delay
|
||||
|
||||
Nest sequences to both trim the beginning and delay when it appears:
|
||||
|
||||
```tsx
|
||||
<Sequence from={30}>
|
||||
<Sequence from={-15}>
|
||||
<MyAnimation />
|
||||
</Sequence>
|
||||
</Sequence>
|
||||
```
|
||||
|
||||
The inner sequence trims 15 frames from the start, and the outer sequence delays the result by 30 frames.

# Using videos in Remotion
|
||||
|
||||
## Prerequisites
|
||||
|
||||
First, the @remotion/media package needs to be installed.
|
||||
If it is not, use the following command:
|
||||
|
||||
```bash
|
||||
npx remotion add @remotion/media # If project uses npm
|
||||
bunx remotion add @remotion/media # If project uses bun
|
||||
yarn remotion add @remotion/media # If project uses yarn
|
||||
pnpm exec remotion add @remotion/media # If project uses pnpm
|
||||
```
|
||||
|
||||
Use `<Video>` from `@remotion/media` to embed videos into your composition.
|
||||
|
||||
```tsx
|
||||
import { Video } from "@remotion/media";
|
||||
import { staticFile } from "remotion";
|
||||
|
||||
export const MyComposition = () => {
|
||||
return <Video src={staticFile("video.mp4")} />;
|
||||
};
|
||||
```
|
||||
|
||||
Remote URLs are also supported:
|
||||
|
||||
```tsx
|
||||
<Video src="https://remotion.media/video.mp4" />
|
||||
```
|
||||
|
||||
## Trimming
|
||||
|
||||
Use `trimBefore` and `trimAfter` to remove portions of the video. Values are in seconds.
|
||||
|
||||
```tsx
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
trimBefore={2 * fps} // Skip the first 2 seconds
|
||||
trimAfter={10 * fps} // End at the 10 second mark
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
## Delaying
|
||||
|
||||
Wrap the video in a `<Sequence>` to delay when it appears:
|
||||
|
||||
```tsx
|
||||
import { Sequence, staticFile } from "remotion";
|
||||
import { Video } from "@remotion/media";
|
||||
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Sequence from={1 * fps}>
|
||||
<Video src={staticFile("video.mp4")} />
|
||||
</Sequence>
|
||||
);
|
||||
```
|
||||
|
||||
The video will appear after 1 second.
|
||||
|
||||
## Sizing and Position
|
||||
|
||||
Use the `style` prop to control size and position:
|
||||
|
||||
```tsx
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
style={{
|
||||
width: 500,
|
||||
height: 300,
|
||||
position: "absolute",
|
||||
top: 100,
|
||||
left: 50,
|
||||
objectFit: "cover",
|
||||
}}
|
||||
/>
|
||||
```
|
||||
|
||||
## Volume
|
||||
|
||||
Set a static volume (0 to 1):
|
||||
|
||||
```tsx
|
||||
<Video src={staticFile("video.mp4")} volume={0.5} />
|
||||
```
|
||||
|
||||
Or use a callback for dynamic volume based on the current frame:
|
||||
|
||||
```tsx
|
||||
import { interpolate } from "remotion";
|
||||
|
||||
const { fps } = useVideoConfig();
|
||||
|
||||
return (
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
volume={(f) =>
|
||||
interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
|
||||
}
|
||||
/>
|
||||
);
|
||||
```
|
||||
|
||||
Use `muted` to silence the video entirely:
|
||||
|
||||
```tsx
|
||||
<Video src={staticFile("video.mp4")} muted />
|
||||
```
|
||||
|
||||
## Speed
|
||||
|
||||
Use `playbackRate` to change the playback speed:
|
||||
|
||||
```tsx
|
||||
<Video src={staticFile("video.mp4")} playbackRate={2} /> {/* 2x speed */}
|
||||
<Video src={staticFile("video.mp4")} playbackRate={0.5} /> {/* Half speed */}
|
||||
```
|
||||
|
||||
Reverse playback is not supported.
|
||||
|
||||
## Looping
|
||||
|
||||
Use `loop` to loop the video indefinitely:
|
||||
|
||||
```tsx
|
||||
<Video src={staticFile("video.mp4")} loop />
|
||||
```
|
||||
|
||||
Use `loopVolumeCurveBehavior` to control how the frame count behaves when looping:
|
||||
|
||||
- `"repeat"`: Frame count resets to 0 each loop (for `volume` callback)
|
||||
- `"extend"`: Frame count continues incrementing
|
||||
|
||||
```tsx
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
loop
|
||||
loopVolumeCurveBehavior="extend"
|
||||
volume={(f) => interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
|
||||
/>
|
||||
```
|
||||
|
||||
## Pitch
|
||||
|
||||
Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
|
||||
|
||||
```tsx
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
toneFrequency={1.5} // Higher pitch
|
||||
/>
|
||||
<Video
|
||||
src={staticFile("video.mp4")}
|
||||
toneFrequency={0.8} // Lower pitch
|
||||
/>
|
||||
```
|
||||
|
||||
Pitch shifting only works during server-side rendering, not in the Remotion Studio preview or in the `<Player />`.
