``` You can also use the default export, since the named export is just a re-export from the Axios factory: ```js import axios from 'axios'; console.log(axios.isCancel('something')); ```` If you use `require` for importing, **only default export is available**: ```js const axios = require('axios'); console.log(axios.isCancel('something')); ``` For cases where something went wrong when trying to import a module into a custom or legacy environment, you can try importing the module package directly: ```js const axios = require('axios/dist/browser/axios.cjs'); // browser commonJS bundle (ES2017) // const axios = require('axios/dist/node/axios.cjs'); // node commonJS bundle (ES2017) ``` ### CDN Using jsDelivr CDN (ES5 UMD browser module): ```html <script src="https://cdn.jsdelivr.net/npm/axios@1.1.2/dist/axios.min.js"></script> ``` Using unpkg CDN: ```html <script src="https://unpkg.com/axios@1.1.2/dist/axios.min.js"></script> ``` ## Example > **Note**: CommonJS usage > In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with `require()`, use the following approach: ```js import axios from 'axios'; //const axios = require('axios'); // legacy way // Make a request for a user with a given ID axios.get('/user?ID=12345') .then(function (response) { // handle success console.log(response); }) .catch(function (error) { // handle error console.log(error); }) .finally(function () { // always executed }); // Optionally the request above could also be done as axios.get('/user', { params: { ID: 12345 } }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }) .finally(function () { // always executed }); // Want to use async/await? Add the `async` keyword to your outer function/method. async function getUser() { try { const response = await axios.get('/user?ID=12345'); console.log(response); } catch (error) { console.error(error); } } ``` > **Note**: `async/await` is part of ECMAScript 2017 and is not supported in Internet > Explorer and older browsers, so use with caution. Performing a `POST` request ```js axios.post('/user', { firstName: 'Fred', lastName:
