How to Use Axios in Vanilla JavaScript

Learn about Axios with practical examples


Axios is a promise-based HTTP client that works both in the browser and in a NodeJS environment. It provides a single API for dealing with XMLHttpRequests and the node's HTTP interface. Axios is similar to the fetch API and it can be used in plain JavaScript as well as in modern JavaScript frameworks like React, Angular, and Vue.

In this article, we will learn about how to use Axios in Vanilla JavaScript. Let's get right into it.


Before installing anything, create a project folder with two files: index.html and index.js file.

Inside that project folder, you can install Axios with the node package manager(NPM), or by just using a CDN on your HTML file where you linked the JavaScript file.

If you prefer to use the node package manager, run the following command in your terminal:

// Install axios
npm i axios -S

It will download the library in the node_modules folder from where you can add it to your project:

<script src="./node_modules/axios/dist/axios.min.js"></script>

If you want to do it quickly, you can just use the CDN in HTML.

<script src=""></script>

Using Axios to GET data from an API

After installing Axios in your project folder, you can use it to do some get requests. We will use JSONplaceholder to get fake data from their API.

Let's open our index.js file and create a function that will print some user information in the console by using Axios.

Have a look at the example below:

const getUsers = () => {
    .then((response) => {
      const users =;
      console.log(`GET users`, users);
    .catch((error) => console.error(error));

As you can see, since Axios is a promise-based HTTP client, we use then() and catch() methods to handle the result.

When the promise is resolved successfully, you will get an object response back. This object has information about the response such as headers, data, config, status and even complete the request object. In our case, we used data to access the user's information in the console.

Here are the console results:


Now, you can easily display this information on the page using the DOM.

POST Request

We can add a new user to our REST API with the method. Just add a new function createUser() inside of index.js .

Here is an example:

const createUser = (user) => {
    .post("", user)
    .then((response) => {
      const addedUser =;
      console.log(`POST: user is added`, addedUser);
      // append to DOM
    .catch((error) => console.error(error));

To create a new user, you need to add a

inside index.html file to capture user information.

DELETE Request

Axios provides axios.delete() method to make a DELETE request.

Here is an example:

const deleteUser = (elem, id) => {
    .then((response) => {
      console.log(`DELETE: user is removed`, id);
      // remove elem from DOM
    .catch((error) => console.error(error));

Now update the createLi() method to attach an event onclick which handles the removal of the user when clicked:

const createLi = (user) => {
  const li = document.createElement("li");
  // add user details to `li`
  li.textContent = `${}: ${user.first_name} ${user.last_name}`;
  // attach onclick event
  li.onclick = (e) => deleteUser(li,;
  return li;


Axios has a huge improvement over XMLHttpRequest with a simple, elegant, and easy-to-use interface. Make sure that we didn't cover everything about it, you need to learn more from other resources.
