>> REST API Cheat Sheet I wish I had created before<<
🏛️ Architectural Principles of REST
1. Client-Server Architecture
- Strict separation of concerns
- Clients make requests
- Servers process and respond
- Enables independent evolution of components
2. Statelessness
- Each request contains complete context
- No server-side session storage
- Improves scalability and reliability
- Enables horizontal scaling
3. Cacheability
- Responses can be cached
- Reduces server load
- Improves response times
- Clearly defined cache control mechanisms
4. Layered System
- Components can be independently replaced
- No direct dependency between layers
- Enhances system flexibility
- Supports complex architectures
5. Uniform Interface
- Standardized communication protocol
- Consistent resource identification
- Manipulation through representations
- Self-descriptive messages
🌐 HTTP Methods Detailed
GET
- Purpose: Retrieve resource data
- Characteristics:
- Safe operation
- Idempotent
- No side effects
- Example: `/users/123`
POST
- Purpose: Create new resources
- Characteristics:
- Submits data to server
- Generates new resource
- Not idempotent
- Example: `/users`
PUT
- Purpose: Complete resource replacement
- Characteristics:
- Updates entire resource
- Idempotent
- Requires full resource representation
- Example: `/users/123`
PATCH
- Purpose: Partial resource modification
- Characteristics:
- Updates specific fields
- More efficient than PUT
- Less bandwidth consumption
- Example: `/users/123`
DELETE
- Purpose: Remove resources
- Characteristics:
- Removes specified resource
- Idempotent
- Can return success/failure status
- Example: `/users/123`
🚦 HTTP Status Codes
2xx Success
- 200 OK: Standard successful response
- 201 Created: Resource successfully generated
- 204 No Content: Successful request with no response body
3xx Redirection
- 301 Moved Permanently: Resource relocated
- 304 Not Modified: Cached resource unchanged
- 307 Temporary Redirect: Temporary resource movement
4xx Client Errors
- 400 Bad Request: Invalid syntax
- 401 Unauthorized: Authentication required
- 403 Forbidden: Insufficient permissions
- 404 Not Found: Resource doesn't exist
- 409 Conflict: Request conflicts with current state
5xx Server Errors
- 500 Internal Server Error: Unexpected server issue
- 502 Bad Gateway: Invalid server response
- 503 Service Unavailable: Temporary server limitations
- 504 Gateway Timeout: Server didn't receive timely response
🏗️ Resource Design Principles
Endpoint Naming
- Use nouns
- Prefer plural forms
- Lowercase with hyphens
- Hierarchical and logical structure
- Example: `/user-profiles/active`
Query Parameters
- Filtering: `?status=active`
- Sorting: `?sort=name`
- Pagination: `?page=2&limit=50`
