// axios. will now provide autocomplete and parameter typings ``` Performing a `GET` request ```js const axios = require('axios'); // 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: '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'); } axios.all([getUserAccount(), getUserPermissions()]) .then(axios.spread(function (acct, perms) { // Both requests are now complete })); ``` ## 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 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 supported 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 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 config will be merged with the instance config. ##### 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]]) ##### axios#getUri([config]) ## Request Config These are the available config options for making requests. Only the `url` is required. Requests will default to `GET` if `method` is not specified. ```js { // `url` is the server URL that will be used for the request url: '/user', // `method` is the request method to be used when making the request method: 'get', // default // `baseURL` will be prepended to `url` unless `url` is absolute. // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs // to methods of that instance. baseURL: 'https://some-domain.com/api/', // `transformRequest` allows changes to the request data before it is sent to the server // This is only applicable for request methods 'PUT', 'POST', 'PATCH' and 'DELETE' // The last function in the array must return a string or an instance of Buffer, ArrayBuffer, // FormData or Stream // You may modify the headers object. transformRequest: [function (data, headers) { // Do whatever you want to transform the data return data; }], // `transformResponse` allows changes to the response data to be made before // it is passed to then/catch transformResponse: [function (data) { // Do whatever you want to transform the data return data; }], // `headers` are custom headers to be sent headers: {'X-Requested-With': 'XMLHttpRequest'}, // `params` are the URL parameters to be sent with the request // Must be a plain object or a URLSearchParams object params: { ID: 12345 }, // `paramsSerializer` is an optional function in charge of serializing `params` // (e.g. https://www.npmjs.com/package/qs, http://api.jquery.com/jquery.param/) paramsSerializer: function (params) { return Qs.stringify(params, {arrayFormat: 'brackets'}) }, // `data` is the data to be sent as the request body // Only applicable for request methods 'PUT', 'POST', and 'PATCH' // When no `transformRequest` is set, must be of one of the following types: // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams // - Browser only: FormData, File, Blob // - Node only: Stream, Buffer data: { firstName: 'Fred' }, // syntax alternative to send data into the body // method post // only the value is sent, not the key data: 'Country=Brasil&City=Belo Horizonte', // `timeout` specifies the number of milliseconds before the request times out. // If the request takes longer than `timeout`, the request will be aborted. timeout: 1000, // default is `0` (no timeout) // `withCredentials` indicates whether or not cross-site Access-Control requests // should be made using credentials withCredentials: false, // default // `adapter` allows custom handling of requests which makes testing easier. // Return a promise and supply a valid response (see lib/adapters/README.md). adapter: function (config) { /* ... */ }, // `auth` indicates that HTTP Basic auth should be used, and supplies credentials. // This will set an `Authorization` header, overwriting any existing // `Authorization` custom headers you have set using `headers`. // Please note that only HTTP Basic auth is configurable through this parameter. // For Bearer tokens and such, use `Authorization` custom headers instead. auth: { username: 'janedoe', password: 's00pers3cret' }, // `responseType` indicates the type of data that the server will respond with // options are: 'arraybuffer', 'document', 'json', 'text', 'stream' // browser only: 'blob' responseType: 'json', // default // `responseEncoding` indicates encoding to use for decoding responses // Note: Ignored for `responseType` of 'stream' or client-side requests responseEncoding: 'utf8', // default // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token xsrfCookieName: 'XSRF-TOKEN', // default // `xsrfHeaderName` is the name of the http header that carries the xsrf token value xsrfHeaderName: 'X-XSRF-TOKEN', // default // `onUploadProgress` allows handling of progress events for uploads onUploadProgress: function (progressEvent) { // Do whatever you want with the native progress event }, // `onDownloadProgress` allows handling of progress events for downloads onDownloadProgress: function (progressEvent) { // Do whatever you want with the native progress event }, // `maxContentLength` defines the max size of the http response content in bytes allowed maxContentLength: 2000, // `validateStatus` defines whether to resolve or reject the promise for a given // HTTP response status code. If `validateStatus` returns `true` (or is set to `null` // or `undefined`), the promise will be resolved; otherwise, the promise will be // rejected. validateStatus: function (status) { return status >= 200 && status < 300; // default }, // `maxRedirects` defines the maximum number of redirects to follow in node.js. // If set to 0, no redirects will be followed. maxRedirects: 5, // default // `socketPath` defines a UNIX Socket to be used in node.js. // e.g. '/var/run/docker.sock' to send requests to the docker daemon. // Only either `socketPath` or `proxy` can be specified. // If both are specified, `socketPath` is used. socketPath: null, // default // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http // and https requests, respectively, in node.js. This allows options to be added like // `keepAlive` that are not enabled by default. httpAgent: new http.Agent({ keepAlive: true }), httpsAgent: new https.Agent({ keepAlive: true }), // 'proxy' defines the hostname and port of the proxy server. // You can also define your proxy using the conventional `http_proxy` and // `https_proxy` environment variables. If you are using environment variables // for your proxy configuration, you can also define a `no_proxy` environment // variable as a comma-separated list of domains that should not be proxied. // Use `false` to disable proxies, ignoring environment variables. // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and // supplies credentials. // This will set an `Proxy-Authorization` header, overwriting any existing // `Proxy-Authorization` custom headers you have set using `headers`. proxy: { host: '127.0.0.1', port: 9000, auth: { username: 'mikeymike', password: 'rapunz3l' } }, // `cancelToken` specifies a cancel token that can be used to cancel the request // (see Cancellation section below for details) cancelToken: new CancelToken(function (cancel) { }) } ``` ## Response Schema The response for a request contains the following information. ```js { // `data` is the response that was provided by the server data: {}, // `status` is the HTTP status code from the server response status: 200, // `statusText` is the HTTP status message from the server response statusText: 'OK', // `headers` the headers that the server responded with // All header names are lower cased headers: {}, // `config` is the config that was provided to `axios` for the request config: {}, // `request` is the request that generated this response // It is the last ClientRequest instance in node.js (in redirects) // and an XMLHttpRequest instance in the browser request: {} } ``` When using `then`, you will receive the response as follows: ```js axios.get('/user/12345') .then(function (response) { console.log(response.data); console.log(response.status); console.log(response.statusText); console.log(response.headers); console.log(response.config); }); ``` When using `catch`, or passing a [rejection callback](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then) as second parameter of `then`, the response will be available through the `error` object as explained in the [Handling Errors](#handling-errors) section. ## Config Defaults You can specify config defaults that will be applied to every request. ### Global axios defaults ```js axios.defaults.baseURL = 'https://api.example.com'; axios.defaults.headers.common['Authorization'] = AUTH_TOKEN; axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'; ``` ### Custom instance defaults ```js // Set config defaults when creating the instance const instance = axios.create({ baseURL: 'https://api.example.com' }); // Alter defaults after instance has been created instance.defaults.headers.common['Authorization'] = AUTH_TOKEN; ``` ### Config order of precedence Config will be merged with an order of precedence. The order is library defaults found in [lib/defaults.js](https://github.com/axios/axios/blob/master/lib/defaults.js#L28), then `defaults` property of the instance, and finally `config` argument for the request. The latter will take precedence over the former. Here's an example. ```js // Create an instance using the config defaults provided by the library // At this point the timeout config value is `0` as is the default for the library const instance = axios.create(); // Override timeout default for the library // Now all requests using this instance will wait 2.5 seconds before timing out instance.defaults.timeout = 2500; // Override timeout for this request as it's known to take a long time instance.get('/longRequest', { timeout: 5000 }); ``` ## Interceptors You can intercept requests or responses before they are handled by `then` or `catch`. ```js // Add a request interceptor axios.interceptors.request.use(function (config) { // Do something before request is sent return config; }, function (error) { // Do something with request error return Promise.reject(error); }); // Add a response interceptor axios.interceptors.response.use(function (response) { // Any status code that lie within the range of 2xx cause this function to trigger // Do something with response data return response; }, function (error) { // Any status codes that falls outside the range of 2xx cause this function to trigger // Do something with response error return Promise.reject(error); }); ``` If you need to remove an interceptor later you can. ```js const myInterceptor = axios.interceptors.request.use(function () {/*...*/}); axios.interceptors.request.eject(myInterceptor); ``` You can add interceptors to a custom instance of axios. ```js const instance = axios.create(); instance.interceptors.request.use(function () {/*...*/}); ``` ## Handling Errors ```js axios.get('/user/12345') .catch(function (error) { if (error.response) { // The request was made and the server responded with a status code // that falls out of the range of 2xx console.log(error.response.data); console.log(error.response.status); console.log(error.response.headers); } else if (error.request) { // The request was made but no response was received // `error.request` is an instance of XMLHttpRequest in the browser and an instance of // http.ClientRequest in node.js console.log(error.request); } else { // Something happened in setting up the request that triggered an Error console.log('Error', error.message); } console.log(error.config); }); ``` Using the `validateStatus` config option, you can define HTTP code(s) that should throw an error. ```js axios.get('/user/12345', { validateStatus: function (status) { return status < 500; // Reject only if the status code is greater than or equal to 500 } }) ``` Using `toJSON` you get an object with more information about the HTTP error. ```js axios.get('/user/12345') .catch(function (error) { console.log(error.toJSON()); }); ``` ## Cancellation You can cancel a request using a *cancel token*. > The axios cancel token API is based on the withdrawn [cancelable promises proposal](https://github.com/tc39/proposal-cancelable-promises). You can create a cancel token using the `CancelToken.source` factory as shown below: ```js const CancelToken = axios.CancelToken; const source = CancelToken.source(); axios.get('/user/12345', { cancelToken: source.token }).catch(function (thrown) { if (axios.isCancel(thrown)) { console.log('Request canceled', thrown.message); } else { // handle error } }); axios.post('/user/12345', { name: 'new name' }, { cancelToken: source.token }) // cancel the request (the message parameter is optional) source.cancel('Operation canceled by the user.'); ``` You can also create a cancel token by passing an executor function to the `CancelToken` constructor: ```js const CancelToken = axios.CancelToken; let cancel; axios.get('/user/12345', { cancelToken: new CancelToken(function executor(c) { // An executor function receives a cancel function as a parameter cancel = c; }) }); // cancel the request cancel(); ``` > Note: you can cancel several requests with the same cancel token. ## Using application/x-www-form-urlencoded format By default, axios serializes JavaScript objects to `JSON`. To send data in the `application/x-www-form-urlencoded` format instead, you can use one of the following options. ### Browser In a browser, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API as follows: ```js const params = new URLSearchParams(); params.append('param1', 'value1'); params.append('param2', 'value2'); axios.post('/foo', params); ``` > Note that `URLSearchParams` is not supported by all browsers (see [caniuse.com](http://www.caniuse.com/#feat=urlsearchparams)), but there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment). Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library: ```js const qs = require('qs'); axios.post('/foo', qs.stringify({ 'bar': 123 })); ``` Or in another way (ES6), ```js import qs from 'qs'; const data = { 'bar': 123 }; const options = { method: 'POST', headers: { 'content-type': 'application/x-www-form-urlencoded' }, data: qs.stringify(data), url, }; axios(options); ``` ### Node.js In node.js, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows: ```js const querystring = require('querystring'); axios.post('http://something.com/', querystring.stringify({ foo: 'bar' })); ``` You can also use the [`qs`](https://github.com/ljharb/qs) library. ###### NOTE The `qs` library is preferable if you need to stringify nested objects, as the `querystring` method has known issues with that use case (https://github.com/nodejs/node-v0.x-archive/issues/1665). ## Semver Until axios reaches a `1.0` release, breaking changes will be released with a new minor version. For example `0.5.1`, and `0.5.4` will have the same API, but `0.6.0` will have breaking changes. ## Promises axios depends on a native ES6 Promise implementation to be [supported](http://caniuse.com/promises). If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise). ## TypeScript axios includes [TypeScript](http://typescriptlang.org) definitions. ```typescript import axios from 'axios'; axios.get('/user?ID=12345'); ``` ## Resources * [Changelog](https://github.com/axios/axios/blob/master/CHANGELOG.md) * [Upgrade Guide](https://github.com/axios/axios/blob/master/UPGRADE_GUIDE.md) * [Ecosystem](https://github.com/axios/axios/blob/master/ECOSYSTEM.md) * [Contributing Guide](https://github.com/axios/axios/blob/master/CONTRIBUTING.md) * [Code of Conduct](https://github.com/axios/axios/blob/master/CODE_OF_CONDUCT.md) ## Credits axios is heavily inspired by the [$http service](https://docs.angularjs.org/api/ng/service/$http) provided in [Angular](https://angularjs.org/).
