What is REST and what are its core principles?
← All API Design questions
Re-explain
REST (Representational State Transfer) is an architectural style for designing networked applications. The core principles are:
- Stateless: Each request contains all information needed to process it
- Client-Server: Separation of concerns between client and server
- Cacheable: Responses should be cacheable when appropriate
- Uniform Interface: Consistent way to interact with resources
- Layered System: Architecture can be composed of hierarchical layers
- Code on Demand (optional): Server can send executable code to client
REST uses resources identified by URIs and standard HTTP methods to perform operations.
