![]() 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. We can also test SuperAgent calls with SuperTest, which is a very handy library in its own right.Making API calls is integral to most applications and while doing this we use an HTTP client usually available as an external library. SuperAgent is mature and battle-tested, which makes it pretty reliable. Consequently, there is a catch block if any error occurs anywhere in the try block, it will be caught, and the error message will be logged to the console. Then, from the res variable, we picked out the date from res.headers and logged status and date on the console.Īfter that, we set the response’s body in the users constant and looped through that array of 10 users to print out each user’s name and ID. Next, in the try block, we called superagent.get with await, which would resolve the promise and give us the result of the HTTP call to our mock users API.
