Note: To fully comprehend this guide, you should be familiar with JavaScript, React, and React hooks, as they are central to it.īefore we get into how to consume APIs, it's important to understand that consuming APIs in React is very different from how it's done in JavaScript. You can consume REST APIs in a React application in a variety of ways, but in this guide, we will look at two of the most popular approaches: Axios (a promise-based HTTP client) and Fetch API (a browser in-built web API). "body": "est rerum tempore vitae\nsequi sint nihil" "body": "quia et suscipit\nsuscipit recusandae consequuntur " JSON is the most widely used file format because it is language-independent and can be read by both humans and machines. This state representation can take the form of JSON (JavaScript Object Notation), XML, or HTML. When a request is made via a REST API, it sends a representation of the resource's current state to the requester or endpoint. It is an acronym that stands for "REpresentational State Transfer." Roy Fielding defined REST in 2000 as an architectural style and methodology commonly used in the development of internet services, such as distributed hypermedia systems. It is a medium that allows different applications to communicate programmatically with one another and return a response in real time. If you've ever spent any time programming or researching programming, you've likely come across the term "API."ĪPI stands for Application Programming Interface. We'll also go over the two main ways to consume RESTful APIs and how to use them with React hooks. In this beginners guide, you will learn how to consume RESTful API in React, including fetching, deleting, and adding data. And you will need to integrate APIs into your React application at some point if you want to build production-ready apps.Įvery developer who wants to build modern, robust web applications with React must understand how to consume APIs to fetch data into their React applications. They also usually need to make updates to that data, send those updates to the server, and keep the cached data on the client in sync with the data on the server.React is a popular frontend library that developers use to create applications. Web applications normally need to fetch data from a server in order to display it. RTK Query ( 9k ⭐) → An optional addon included in the Redux Toolkit package, and its functionality is built on top of the other APIs in Redux Toolkit. Urql ( 8k ⭐) → A highly customizable and versatile GraphQL client with which you add on features like normalized caching as you grow. Relay ( 17k ⭐) → The production-ready GraphQL client for React, developed by Facebook, was designed to be performant from the ground up, built upon locally declaring data dependencies for components. Use it to fetch, cache, and modify application data, all while automatically updating your UI. SWR ( 26k ⭐) → A React Hooks library for data fetching, created by Next.js team, lightweight, and backend agnostic.Īpollo Client ( 18k ⭐) → A comprehensive state management library for JavaScript that enables you to manage both local and remote data with GraphQL. It is backend agnostic so you can use React Query with literally any asynchronous data fetching client. React Query ( 33k ⭐) → A library handles fetching, caching, background updates and stale data out of the box with zero-configuration. On the server-side it uses the native NodeJS http module, while on the browser it uses XMLHttpRequests. Popular librariesĪxios ( 99k ⭐) → A promise-based isomorphic HTTP client which can run in the browser and NodeJS with the same codebase. Using a data fetching library is preferred as following solutions will simplify the logic of data fetching in your project with tons of amazing built-in features. Fetching data in React using XMLHttpRequest and Fetch API is fine but require a lot of boilerplate codes.
