In this blog, we’ll look at how to retrieve and display data from APIs for use in a ReactJS app<\/strong>. We’ll go over the various methods for fetching data in a React application. APIs allow us to fetch data from servers and display it in our application. Let’s first define what an API is.<\/p>

API stands for “Application Programming Interface<\/strong>,” which is a means of communication between different applications. ReactJS is an open-source JavaScript-based library developed by Facebook for creating web application user interfaces. Because ReactJS is dynamic, we can access data through APIs and display it in our application.<\/p>

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

When we use APIs<\/strong>, we don’t need a backend and don’t have to create anything from scratch. We mostly use the REST API or the GraphQL API<\/strong> to access the server’s data. Before we get into the details, we should understand how an API works.<\/p>

How does an API work?<\/h1>

An API (Application Programming Interface)<\/strong> serves as a bridge between various software applications, allowing them to communicate with one another. When you retrieve data from an API, your application sends a request to the server, which then returns the requested data. This data is typically in JSON format<\/strong> and can be easily manipulated in JavaScript.<\/p>

Methods to Fetch and Display Data from API:<\/h1>

We commonly use a Web API known as REST<\/strong>, or Representational<\/strong> State Transfer API, which consists of HTTP methods for retrieving data from the server and displaying it in the application. A REST API consists of several methods, which are discussed further below:<\/p>

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

    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. We retrieve data using the GET method.<\/p>
