Different Ways to Fetch Data in React Js?

Hi Everyone,

In this blog, we’ll see how to fetch and display data using APIs and use it in a React app. There are multiple ways to fetch data in a React application, and in this blog, we’ll walk you through those methods. With the help of APIs, we can fetch the data from servers and display it in our application.

Firstly, will see how APIs work.

The workings of an API are very easy to understand. Let’s understand it with an example. Say we want to build a new application and we don’t have our own backend. Now, to display the news in our application, we need some third-party APIs to access their backend server and display the data in our app.

Now, there are 3 things we must have noted, i.e., an application, a server, and an API. Most times, the API is in between the app and server because whenever the client requests the data, the API makes a GET request to the server and sends that back to the application for display.

Methods of fetching data using API

API stands for Application Programming Interface. The most popular Web Api used is a Representational State Transfer API or RESTFUL API. Web APIs are used to fetch data from a database and save data back to the database. Using Web APIs requires the use of HTTP request methods there are different HTTP request methods like GET, POST, PUT, DELETE, etc. Let’s have a brief description of the mentioned HTTP request.

• GET: Used to request data from an endpoint
• POST: Sends data to an endpoint
• DELETE: Remove data from an endpoint.
• PUT: Update a record or data value at an endpoint.

1. Fetch Method:-

The fetch() method in Js is used to request to the server and load the information in the web pages. the request can be of any APIs that return the data of the format JSON or XML. This method returns a promise.

2. Async-Await:-

it is the preferred way of fetching the data from an API as it enables us to remove our .then() callbacks and return asynchronously resolved data in the async block, we can use Await function to wait for the promise.

3 . Axios library:-

With Axios, we can easily and asynchronously HTTP request to REST APIs and perform create, read, update and delete operations. Axios can be imported in plain Javascript or with any library accordingly.

4. Custom Hook:-

it is basically a React component whose name will start with "use" like useFetch. It can use one or more React hooks inside them.

Usage in the component

import the useFetch hook and pass the URL of the API endpoint from where you want to fetch data.

Now just like any React hook, we can directly use our custom hook to fetch the data.

5. React Query library:-

with this, we can achieve more than just fetching data. It provides support for catching and refetching, which impacts the overall user experience by preventing irregularities and ensuring our app feels faster.
