>> 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`
