Rest & Restfulness API Design Principles
Short summary
REST (Representational State Transfer) uses HTTP methods and stateless communication to enable scalable web APIs. Key design principles include resource-based URLs using nouns not verbs, proper HTTP method usage (GET/POST/PUT/DELETE), stateless architecture, and HTTP caching headers to reduce latency. RESTful APIs are platform-independent, making them foundational for building interoperable web services.
- •REST operates on stateless HTTP communication for scalable, platform-independent APIs
- •Use resource-based URLs with nouns and proper HTTP methods (GET/POST/PUT/DELETE)
- •Implement HTTP caching headers to reduce latency and improve performance
