RESTful API design is a critical aspect of building scalable, maintainable, and user-friendly web services. Here's a concise guide to best practices and principles:

Core Principles ✅

  1. Stateless Communication
    Each request from a client must contain all the information the server needs to fulfill it.

    RESTful_Stateless

  2. Resource-Based Endpoints
    Use nouns for endpoints (e.g., /users, /products) to represent resources.

  3. Standard HTTP Methods

    • GET for retrieving data
    • POST for creating resources
    • PUT for updating
    • DELETE for removing
    • PATCH for partial updates

  4. Consistent Resource Naming
    Use plural nouns and avoid camelCase (e.g., GET /books vs. GET /bookData).

Best Practices 📝

  • Versioning
    Include API versions in URLs (e.g., /api/v1/users).
  • Status Codes
    Use appropriate HTTP status codes (e.g., 200 OK, 404 Not Found).
  • Pagination
    Implement pagination for large datasets (e.g., ?page=2&limit=10).
  • Security
    Always use HTTPS and validate inputs.

Common Pitfalls ⚠️

  • Avoid using verbs in endpoints (e.g., POST /create_user → GET /users).
  • Do not overuse subresources (e.g., /user/orders is better than /user/order/123/items).
