In this blog, we\u2019ll learn how to fetch and display data from APIs and use it in a ReactJS app.<\/strong> There are multiple ways to fetch data in a React application, and we\u2019ll walk you through those methods. With the help of APIs, we can fetch the data from servers and display it in our application. Let’s first understand what an API is.<\/p>\n\n\n\n

API <\/strong>stands for “Application Programming Interface”,<\/strong> which is a method of communication between different applications. ReactJS <\/strong>is an open-source JavaScript-based library developed by Facebook used to create web applications’ user interfaces. As ReactJS is dynamic in nature, we can get the data using APIs and display it in our application.<\/p>\n\n\n\n

To render some data in our front end, we either need a backend to store our data and then make use of the data, or we can simply use APIs to have some mock data while building an application.<\/p>\n\n\n\n

When we use APIs, we don\u2019t need a backend and are also not required to build anything from scratch. Mostly, we use the REST API or the GraphQL API to access the data added to the server. Before we get into depth, we should understand how an API works.<\/p>\n\n\n\n

How does an API work<\/strong>?<\/h2>\n\n\n\n

The workings of an API are very easy to understand. Here’s an example, say we want to build a new application but don\u2019t 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.<\/p>\n\n\n\n

Now, there are three things we must have noted: an application, a server, and an API. <\/strong>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.<\/em><\/p>\n\n\n\n

Methods to Fetch and Display Data from API<\/strong>:<\/h2>\n\n\n\n

We commonly use a Web API called REST, or REpresentational State Transfer API<\/strong>, which consists of HTTP methods to fetch data from the server and display it in the application. A REST API has several methods, which are discussed further below:<\/p>\n\n\n\n

    \n
  1. GET: <\/strong>This method is used to fetch data from a server endpoint.<\/li>\n\n\n\n
  2. POST: <\/strong>This method is used to post the data to a server endpoint.<\/li>\n\n\n\n
  3. DELETE: <\/strong>This method is used to delete the data from a server endpoint.<\/li>\n\n\n\n
  4. PUT: <\/strong>This method is used to update or modify the data from a server endpoint.<\/li>\n<\/ol>\n\n\n\n

    Now as you have understood all the methods of the API, we can now move on to how the data is fetched from the server. To fetch the data, we use the GET <\/strong>method.<\/p>\n\n\n\n

    The different ways of Fetching the data in a React application are given below:<\/em><\/p>\n\n\n\n
