Study Notes

RESTful API Architecture

  • REST stands for Representational State of Resource
  • Web services that adhere to REST constraints are called RESTful APIs
  • REST defines a set of constraints for web services to ensure scalability, flexibility, and maintainability

Client Responsibility

  • The client is responsible for initiating requests and cache responses from the server
  • Each request from the client to the server must contain all the necessary information

Uniform Interface

  • The uniform interface ensures that different resources can be accessed and manipulated in a uniform way
  • It enables clients to discover and access resources without prior knowledge of the server's implementation

Stateless Principle

  • The stateless principle ensures that each request contains all the necessary information, making the server stateless
  • This allows the server to process requests independently without remembering previous requests

Client-Server Communication

  • The key characteristic of communication between client and server is that it is stateless and uniform
  • Clients can cache server responses, which benefits the client by reducing latency and improving performance

HTTP Methods

  • HTTP method POST typically corresponds to the 'create' operation in a RESTful API
  • HTTP method PUT is commonly used for the 'update' operation in a RESTful API
  • HTTP method GET is typically used for read operations in a RESTful API
  • HTTP method DELETE typically corresponds to the 'delete' operation in a RESTful API

Next.js API Routes

  • Next.js API routes are built using RESTful principles for clients to interact with the server
