    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
