REST (Representational State Transfer) is a popular architectural style for designing networked applications. It is used to build web services that are lightweight, maintainable, and scalable.
Key Concepts
- Client-Server Architecture: REST follows a client-server architecture, where the client (usually a web browser or mobile app) requests data from the server.
- Stateless: Each request from a client to a server must contain all the information needed to understand and complete the request. The server does not store the client's session information.
- Resource-Based: REST uses resources to represent data. Each resource is identified by a URL (Uniform Resource Locator).
RESTful API
A RESTful API is an API that adheres to the REST architectural style. Here are some key characteristics of a RESTful API:
- Resource-Based URLs: URLs represent resources and are used to access data.
- HTTP Methods: The HTTP methods (GET, POST, PUT, DELETE) are used to perform CRUD (Create, Read, Update, Delete) operations on resources.
- Standardized Media Types: Responses are typically formatted in JSON or XML.
Getting Started
To get started with RESTful APIs, you can:
- Learn about HTTP Methods: Understand how GET, POST, PUT, and DELETE are used.
- Explore JSON and XML: Learn about these popular data formats.
- Experiment with APIs: Use online tools like Postman to test API requests.
