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: 'Flintstone' }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); ``` Performing multiple concurrent requests ```js function getUserAccount() { return axios.get('/user/12345'); } function getUserPermissions() { return axios.get('/user/12345/permissions'); } Promise.all([getUserAccount(), getUserPermissions()]) .then(function (results) { const acct = results[0]; const perm = results[1]; }); ``` ## axios API Requests can be made by passing the relevant config to `axios`. ##### axios(config) ```js // Send a POST request axios({ method: 'post', url: '/user/12345', data: { firstName: 'Fred', lastName: 'Flintstone' } }); ``` ```js // GET request for remote image in node.js axios({ method: 'get', url: 'http://bit.ly/2mTM3nY', responseType: 'stream' }) .then(function (response) { response.data.pipe(fs.createWriteStream('ada_lovelace.jpg')) }); ``` ##### axios(url[, config]) ```js // Send a GET request (default method) axios('/user/12345'); ``` ### Request method aliases For convenience, aliases have been provided for all common request methods. ##### axios.request(config) ##### axios.get(url[, config]) ##### axios.delete(url[, config]) ##### axios.head(url[, config]) ##### axios.options(url[, config]) ##### axios.post(url[, data[, config]]) ##### axios.put(url[, data[, config]]) ##### axios.patch(url[, data[, config]]) ###### NOTE When using the alias methods `url`, `method`, and `data` properties don't need to be specified in config. ### Concurrency (Deprecated) Please use `Promise.all` to replace the below functions. Helper functions for dealing with concurrent requests. axios.all(iterable) axios.spread(callback) ### Creating an instance You can create a new instance of axios with a custom config. ##### axios.create([config]) ```js const instance = axios.create({ baseURL: 'https://some-domain.com/api/', timeout: 1000, headers: {'X-Custom-Header': 'foobar'} }); ``` ### Instance methods The available instance methods are listed below. The specified confi
