REST

Enhancing Web Development with RESTful Architectures #

Introduction #

Representational State Transfer (REST) is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol, virtually always HTTP.

Principles of REST #

RESTful applications use HTTP methods to map CRUD (create, retrieve, update, delete) operations to endpoints, which are typically resources or collections of resources. Here are some key principles:

  1. Client-Server Architecture: The client and server are separate entities communicating over a network. This separation allows each to be developed and scaled independently.

  2. Stateless: Each HTTP request from the client to server must contain all the information needed to understand and process the request. The server should not store anything about the latest HTTP request the client made.

  3. Cacheable: Responses from the server can be cached by the client to improve performance.

  4. Uniform Interface: The method of communication between the client and server is uniform, simplifying the architecture overall.

HTTP Methods in REST #

RESTful APIs use standard HTTP methods, each of which typically corresponds to a specific CRUD operation:

  • GET: Retrieve a resource or list of resources.
  • POST: Create a new resource.
  • PUT: Update an existing resource.
  • DELETE: Remove a resource.
