![]() ![]() apiserver: This is a Node.js application written using the Express Framework that will contain the REST APIs.We have created the following applications to simulate APIs on the server consumed by other applications on the server and the browser with REST APIs : Installing Axios and Other Prerequisites For the Examples In the following sections, we will look at examples of using these features of Axios in our applications. It supports all modern browsers, including support for IE 8 and higher. One of the important capabilities of Axios is its isomorphic nature which means it can run in the browser as well as in server-side Node.js applications with the same codebase.Īxios is also a promise-based HTTP client that can be used in plain JavaScript as well as in advanced JavaScript frameworks like React, Vue.js, and Angular. It is similar to the Fetch API and returns a JavaScript Promise object but also includes many powerful features. JavaScript already provides built-in objects: XMLHttpRequest and the Fetch API for interacting with APIs.Īxios in contrast to these built-in objects is an open-source library that we need to include in our application for making API calls over HTTP. ![]() Let us first understand why do we need to use a library like Axios. This article is accompanied by a working code example on GitHub. In this article, we will understand Axios and use its capabilities to make different types of REST API calls from JavaScript applications. We can make API calls with Axios from JavaScript applications irrespective of whether the JavaScript is running on the front-end like a browser or the server-side. Axios is a popular HTTP client available as a JavaScript library with more than 22 million weekly downloads as of May 2022. Making API calls is integral to most applications and while doing this we use an HTTP client usually available as an external library. ![]()
