| <!-- /TOC --> | ||||
| 
 | ||||
| ## Motivation | ||||
| 
 | ||||
| Instead of implementing `XMLHttpRequest` in Node.js to run browser-specific [Fetch polyfill](https://github.com/github/fetch), why not go from native `http` to `fetch` API directly? Hence, `node-fetch`, minimal code for a `window.fetch` compatible API on Node.js runtime. | ||||
| 
 | ||||
| See Matt Andrews' [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch) or Leonardo Quixada's [cross-fetch](https://github.com/lquixada/cross-fetch) for isomorphic usage (exports `node-fetch` for server-side, `whatwg-fetch` for client-side). | ||||
| 
 | ||||
| ## Features | ||||
| 
 | ||||
| - Stay consistent with `window.fetch` API. | ||||
| - Make conscious trade-off when following [WHATWG fetch spec][whatwg-fetch] and [stream spec](https://streams.spec.whatwg.org/) implementation details, document known differences. | ||||
| - Use native promise but allow substituting it with [insert your favorite promise library]. | ||||
| - Use native Node streams for body on both request and response. | ||||
| - Decode content encoding (gzip/deflate) properly and convert string output (such as `res.text()` and `res.json()`) to UTF-8 automatically. | ||||
| - Useful extensions such as timeout, redirect limit, response size limit, [explicit errors](ERROR-HANDLING.md) for troubleshooting. | ||||
| 
 | ||||
| ## Difference from client-side fetch | ||||
| 
 | ||||
| - See [Known Differences](LIMITS.md) for details. | ||||
| - If you happen to use a missing feature that `window.fetch` offers, feel free to open an issue. | ||||
| - Pull requests are welcomed too! | ||||
| 
 | ||||
| ## Installation | ||||
| 
 | ||||
| Current stable release (`2.x`) | ||||
| 
 | ||||
| ```sh | ||||
| $ npm install node-fetch | ||||
| ``` | ||||
| 
 | ||||
| ## Loading and configuring the module | ||||
| We suggest you load the module via `require` until the stabilization of ES modules in node: | ||||
| ```js | ||||
| const fetch = require('node-fetch'); | ||||
| ``` | ||||
| 
 | ||||
| If you are using a Promise library other than native, set it through `fetch.Promise`: | ||||
| ```js | ||||
| const Bluebird = require('bluebird'); | ||||
| 
 | ||||
| fetch.Promise = Bluebird; | ||||
| ``` | ||||
| 
 | ||||
| ## Common Usage | ||||
| 
 | ||||
| NOTE: The documentation below is up-to-date with `2.x` releases; see the [`1.x` readme](https://github.com/bitinn/node-fetch/blob/1.x/README.md), [changelog](https://github.com/bitinn/node-fetch/blob/1.x/CHANGELOG.md) and [2.x upgrade guide](UPGRADE-GUIDE.md) for the differences. | ||||
| 
 | ||||
| #### Plain text or HTML | ||||
| ```js | ||||
| fetch('https://github.com/') | ||||
|     .then(res => res.text()) | ||||
|     .then(body => console.log(body)); | ||||
| ``` | ||||
| 
 | ||||
| #### JSON | ||||
| 
 | ||||
| ```js | ||||
| 
 | ||||
| fetch('https://api.github.com/users/github') | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Simple Post | ||||
| ```js | ||||
| fetch('https://httpbin.org/post', { method: 'POST', body: 'a=1' }) | ||||
|     .then(res => res.json()) // expecting a json response | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Post with JSON | ||||
| 
 | ||||
| ```js | ||||
| const body = { a: 1 }; | ||||
| 
 | ||||
| fetch('https://httpbin.org/post', { | ||||
|         method: 'post', | ||||
|         body:    JSON.stringify(body), | ||||
|         headers: { 'Content-Type': 'application/json' }, | ||||
|     }) | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Post with form parameters | ||||
| `URLSearchParams` is available in Node.js as of v7.5.0. See [official documentation](https://nodejs.org/api/url.html#url_class_urlsearchparams) for more usage methods. | ||||
| 
 | ||||
| NOTE: The `Content-Type` header is only set automatically to `x-www-form-urlencoded` when an instance of `URLSearchParams` is given as such: | ||||
| 
 | ||||
| ```js | ||||
| const { URLSearchParams } = require('url'); | ||||
| 
 | ||||
| const params = new URLSearchParams(); | ||||
| params.append('a', 1); | ||||
| 
 | ||||
| fetch('https://httpbin.org/post', { method: 'POST', body: params }) | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Handling exceptions | ||||
| NOTE: 3xx-5xx responses are *NOT* exceptions and should be handled in `then()`; see the next section for more information. | ||||
| 
 | ||||
| Adding a catch to the fetch promise chain will catch *all* exceptions, such as errors originating from node core libraries, network errors and operational errors, which are instances of FetchError. See the [error handling document](ERROR-HANDLING.md)  for more details. | ||||
| 
 | ||||
| ```js | ||||
| fetch('https://domain.invalid/') | ||||
|     .catch(err => console.error(err)); | ||||
| ``` | ||||
| 
 | ||||
| #### Handling client and server errors | ||||
| It is common to create a helper function to check that the response contains no client (4xx) or server (5xx) error responses: | ||||
| 
 | ||||
| ```js | ||||
| function checkStatus(res) { | ||||
|     if (res.ok) { // res.status >= 200 && res.status < 300 | ||||
|         return res; | ||||
|     } else { | ||||
|         throw MyCustomError(res.statusText); | ||||
|     } | ||||
| } | ||||
| 
 | ||||
| fetch('https://httpbin.org/status/400') | ||||
|     .then(checkStatus) | ||||
|     .then(res => console.log('will not get here...')) | ||||
| ``` | ||||
| 
 | ||||
| ## Advanced Usage | ||||
| 
 | ||||
| #### Streams | ||||
| The "Node.js way" is to use streams when possible: | ||||
| 
 | ||||
| ```js | ||||
| fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') | ||||
|     .then(res => { | ||||
|         const dest = fs.createWriteStream('./octocat.png'); | ||||
|         res.body.pipe(dest); | ||||
|     }); | ||||
| ``` | ||||
| 
 | ||||
| #### Buffer | ||||
| If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API) | ||||
| 
 | ||||
| ```js | ||||
| const fileType = require('file-type'); | ||||
| 
 | ||||
| fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') | ||||
|     .then(res => res.buffer()) | ||||
|     .then(buffer => fileType(buffer)) | ||||
|     .then(type => { /* ... */ }); | ||||
| ``` | ||||
| 
 | ||||
| #### Accessing Headers and other Meta data | ||||
| ```js | ||||
| fetch('https://github.com/') | ||||
|     .then(res => { | ||||
|         console.log(res.ok); | ||||
|         console.log(res.status); | ||||
|         console.log(res.statusText); | ||||
|         console.log(res.headers.raw()); | ||||
|         console.log(res.headers.get('content-type')); | ||||
|     }); | ||||
| ``` | ||||
| 
 | ||||
| #### Extract Set-Cookie Header | ||||
| 
 | ||||
| Unlike browsers, you can access raw `Set-Cookie` headers manually using `Headers.raw()`. This is a `node-fetch` only API. | ||||
| 
 | ||||
| ```js | ||||
| fetch(url).then(res => { | ||||
|     // returns an array of values, instead of a string of comma-separated values | ||||
|     console.log(res.headers.raw()['set-cookie']); | ||||
| }); | ||||
| ``` | ||||
| 
 | ||||
| #### Post data using a file stream | ||||
| 
 | ||||
| ```js | ||||
| const { createReadStream } = require('fs'); | ||||
| 
 | ||||
| const stream = createReadStream('input.txt'); | ||||
| 
 | ||||
| fetch('https://httpbin.org/post', { method: 'POST', body: stream }) | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Post with form-data (detect multipart) | ||||
| 
 | ||||
| ```js | ||||
| const FormData = require('form-data'); | ||||
| 
 | ||||
| const form = new FormData(); | ||||
| form.append('a', 1); | ||||
| 
 | ||||
| fetch('https://httpbin.org/post', { method: 'POST', body: form }) | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| 
 | ||||
| // OR, using custom headers | ||||
| // NOTE: getHeaders() is non-standard API | ||||
| 
 | ||||
| const form = new FormData(); | ||||
| form.append('a', 1); | ||||
| 
 | ||||
| const options = { | ||||
|     method: 'POST', | ||||
|     body: form, | ||||
|     headers: form.getHeaders() | ||||
| } | ||||
| 
 | ||||
| fetch('https://httpbin.org/post', options) | ||||
|     .then(res => res.json()) | ||||
|     .then(json => console.log(json)); | ||||
| ``` | ||||
| 
 | ||||
| #### Request cancellation with AbortSignal | ||||
| 
 | ||||
| > NOTE: You may cancel streamed requests only on Node >= v8.0.0 | ||||
| 
 | ||||
| You may cancel requests with `AbortController`. A suggested implementation is [`abort-controller`](https://www.npmjs.com/package/abort-controller). | ||||
| 
 | ||||
| An example of timing out a request after 150ms could be achieved as the following: | ||||
| 
 | ||||
| ```js | ||||
| import AbortController from 'abort-controller'; | ||||
| 
 | ||||
| const controller = new AbortController(); | ||||
| const timeout = setTimeout( | ||||
|   () => { controller.abort(); }, | ||||
|   150, | ||||
| ); | ||||
| 
 | ||||
| fetch(url, { signal: controller.signal }) | ||||
|   .then(res => res.json()) | ||||
|   .then( | ||||
|     data => { | ||||
|       useData(data) | ||||
|     }, | ||||
|     err => { | ||||
|       if (err.name === 'AbortError') { | ||||
|         // request was aborted | ||||
|       } | ||||
|     }, | ||||
|   ) | ||||
|   .finally(() => { | ||||
|     clearTimeout(timeout); | ||||
|   }); | ||||
| ``` | ||||
| 
 | ||||
| See [test cases](https://github.com/bitinn/node-fetch/blob/master/test/test.js) for more examples. | ||||
| 
 | ||||
| 
 | ||||
| ## API | ||||
| 
 | ||||
| ### fetch(url[, options]) | ||||
| 
 | ||||
| - `url` A string representing the URL for fetching | ||||
| - `options` [Options](#fetch-options) for the HTTP(S) request | ||||
| - Returns: <code>Promise<[Response](#class-response)></code> | ||||
| 
 | ||||
| Perform an HTTP(S) fetch. | ||||
| 
 | ||||
| `url` should be an absolute url, such as `https://example.com/`. A path-relative URL (`/file/under/root`) or protocol-relative URL (`//can-be-http-or-https.com/`) will result in a rejected `Promise`. | ||||
| 
 | ||||
| <a id="fetch-options"></a> | ||||
| ### Options | ||||
| 
 | ||||
| The default values are shown after each option key. | ||||
| 
 | ||||
| ```js | ||||
| { | ||||
|     // These properties are part of the Fetch Standard | ||||
|     method: 'GET', | ||||
|     headers: {},        // request headers. format is the identical to that accepted by the Headers constructor (see below) | ||||
|     body: null,         // request body. can be null, a string, a Buffer, a Blob, or a Node.js Readable stream | ||||
|     redirect: 'follow', // set to `manual` to extract redirect headers, `error` to reject redirect | ||||
|     signal: null,       // pass an instance of AbortSignal to optionally abort requests | ||||
| 
 | ||||
|     // The following properties are node-fetch extensions | ||||
|     follow: 20,         // maximum redirect count. 0 to not follow redirect | ||||
|     timeout: 0,         // req/res timeout in ms, it resets on redirect. 0 to disable (OS limit applies). Signal is recommended instead. | ||||
|     compress: true,     // support gzip/deflate content encoding. false to disable | ||||
|     size: 0,            // maximum response body size in bytes. 0 to disable | ||||
|     agent: null         // http(s).Agent instance or function that returns an instance (see below) | ||||
| } | ||||
| ``` | ||||
| 
 | ||||
| ##### Default Headers | ||||
| 
 | ||||
| If no values are set, the following request headers will be sent automatically: | ||||
| 
 | ||||
| Header              | Value | ||||
| ------------------- | -------------------------------------------------------- | ||||
| `Accept-Encoding`   | `gzip,deflate` _(when `options.compress === true`)_ | ||||
| `Accept`            | `*/*` | ||||
| `Connection`        | `close` _(when no `options.agent` is present)_ | ||||
| `Content-Length`    | _(automatically calculated, if possible)_ | ||||
| `Transfer-Encoding` | `chunked` _(when `req.body` is a stream)_ | ||||
| `User-Agent`        | `node-fetch/1.0 (+https://github.com/bitinn/node-fetch)` | ||||
| 
 | ||||
| Note: when `body` is a `Stream`, `Content-Length` is not set automatically. | ||||
| 
 | ||||
| ##### Custom Agent | ||||
| 
 | ||||
| The `agent` option allows you to specify networking related options which are out of the scope of Fetch, including and not limited to the following: | ||||
| 
 | ||||
| - Support self-signed certificate | ||||
| - Use only IPv4 or IPv6 | ||||
| - Custom DNS Lookup | ||||
| 
 | ||||
| See [`http.Agent`](https://nodejs.org/api/http.html#http_new_agent_options) for more information. | ||||
| 
 | ||||
| In addition, the `agent` option accepts a function that returns `http`(s)`.Agent` instance given current [URL](https://nodejs.org/api/url.html), this is useful during a redirection chain across HTTP and HTTPS protocol. | ||||
| 
 | ||||
| ```js | ||||
| const httpAgent = new http.Agent({ | ||||
|     keepAlive: true | ||||
| }); | ||||
| const httpsAgent = new https.Agent({ | ||||
|     keepAlive: true | ||||
| }); | ||||
| 
 | ||||
| const options = { | ||||
|     agent: function (_parsedURL) { | ||||
|         if (_parsedURL.protocol == 'http:') { | ||||
|             return httpAgent; | ||||
|         } else { | ||||
|             return httpsAgent; | ||||
|         } | ||||
|     } | ||||
| } | ||||
| ``` | ||||
| 
 | ||||
| <a id="class-request"></a> | ||||
| ### Class: Request | ||||
| 
 | ||||
| An HTTP(S) request containing information about URL, method, headers, and the body. This class implements the [Body](#iface-body) interface. | ||||
| 
 | ||||
| Due to the nature of Node.js, the following properties are not implemented at this moment: | ||||
| 
 | ||||
| - `type` | ||||
| - `destination` | ||||
| - `referrer` | ||||
| - `referrerPolicy` | ||||
| - `mode` | ||||
| - `credentials` | ||||
| - `cache` | ||||
| - `integrity` | ||||
| - `keepalive` | ||||
| 
 | ||||
| The following node-fetch extension properties are provided: | ||||
| 
 | ||||
| - `follow` | ||||
| - `compress` | ||||
| - `counter` | ||||
| - `agent` | ||||
| 
 | ||||
| See [options](#fetch-options) for exact meaning of these extensions. | ||||
| 
 | ||||
| #### new Request(input[, options]) | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| - `input` A string representing a URL, or another `Request` (which will be cloned) | ||||
| - `options` [Options][#fetch-options] for the HTTP(S) request | ||||
| 
 | ||||
| Constructs a new `Request` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Request/Request). | ||||
| 
 | ||||
| In most cases, directly `fetch(url, options)` is simpler than creating a `Request` object. | ||||
| 
 | ||||
| <a id="class-response"></a> | ||||
| ### Class: Response | ||||
| 
 | ||||
| An HTTP(S) response. This class implements the [Body](#iface-body) interface. | ||||
| 
 | ||||
| The following properties are not implemented in node-fetch at this moment: | ||||
| 
 | ||||
| - `Response.error()` | ||||
| - `Response.redirect()` | ||||
| - `type` | ||||
| - `trailer` | ||||
| 
 | ||||
| #### new Response([body[, options]]) | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| - `body` A `String` or [`Readable` stream][node-readable] | ||||
| - `options` A [`ResponseInit`][response-init] options dictionary | ||||
| 
 | ||||
| Constructs a new `Response` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Response/Response). | ||||
| 
 | ||||
| Because Node.js does not implement service workers (for which this class was designed), one rarely has to construct a `Response` directly. | ||||
| 
 | ||||
| #### response.ok | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| Convenience property representing if the request ended normally. Will evaluate to true if the response status was greater than or equal to 200 but smaller than 300. | ||||
| 
 | ||||
| #### response.redirected | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| Convenience property representing if the request has been redirected at least once. Will evaluate to true if the internal redirect counter is greater than 0. | ||||
| 
 | ||||
| <a id="class-headers"></a> | ||||
| ### Class: Headers | ||||
| 
 | ||||
| This class allows manipulating and iterating over a set of HTTP headers. All methods specified in the [Fetch Standard][whatwg-fetch] are implemented. | ||||
| 
 | ||||
| #### new Headers([init]) | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| - `init` Optional argument to pre-fill the `Headers` object | ||||
| 
 | ||||
| Construct a new `Headers` object. `init` can be either `null`, a `Headers` object, an key-value map object or any iterable object. | ||||
| 
 | ||||
| ```js | ||||
| // Example adapted from https://fetch.spec.whatwg.org/#example-headers-class | ||||
| 
 | ||||
| const meta = { | ||||
|   'Content-Type': 'text/xml', | ||||
|   'Breaking-Bad': '<3' | ||||
| }; | ||||
| const headers = new Headers(meta); | ||||
| 
 | ||||
| // The above is equivalent to | ||||
| const meta = [ | ||||
|   [ 'Content-Type', 'text/xml' ], | ||||
|   [ 'Breaking-Bad', '<3' ] | ||||
| ]; | ||||
| const headers = new Headers(meta); | ||||
| 
 | ||||
| // You can in fact use any iterable objects, like a Map or even another Headers | ||||
| const meta = new Map(); | ||||
| meta.set('Content-Type', 'text/xml'); | ||||
| meta.set('Breaking-Bad', '<3'); | ||||
| const headers = new Headers(meta); | ||||
| const copyOfHeaders = new Headers(headers); | ||||
| ``` | ||||
| 
 | ||||
| <a id="iface-body"></a> | ||||
| ### Interface: Body | ||||
| 
 | ||||
| `Body` is an abstract interface with methods that are applicable to both `Request` and `Response` classes. | ||||
| 
 | ||||
| The following methods are not yet implemented in node-fetch at this moment: | ||||
| 
 | ||||
| - `formData()` | ||||
| 
 | ||||
| #### body.body | ||||
| 
 | ||||
| <small>*(deviation from spec)*</small> | ||||
| 
 | ||||
| * Node.js [`Readable` stream][node-readable] | ||||
| 
 | ||||
| Data are encapsulated in the `Body` object. Note that while the [Fetch Standard][whatwg-fetch] requires the property to always be a WHATWG `ReadableStream`, in node-fetch it is a Node.js [`Readable` stream][node-readable]. | ||||
| 
 | ||||
| #### body.bodyUsed | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| * `Boolean` | ||||
| 
 | ||||
| A boolean property for if this body has been consumed. Per the specs, a consumed body cannot be used again. | ||||
| 
 | ||||
| #### body.arrayBuffer() | ||||
| #### body.blob() | ||||
| #### body.json() | ||||
| #### body.text() | ||||
| 
 | ||||
| <small>*(spec-compliant)*</small> | ||||
| 
 | ||||
| * Returns: <code>Promise</code> | ||||
| 
 | ||||
| Consume the body and return a promise that will resolve to one of these formats. | ||||
| 
 | ||||
| #### body.buffer() | ||||
| 
 | ||||
| <small>*(node-fetch extension)*</small> | ||||
| 
 | ||||
| * Returns: <code>Promise<Buffer></code> | ||||
| 
 | ||||
| Consume the body and return a promise that will resolve to a Buffer. | ||||
| 
 | ||||
| #### body.textConverted() | ||||
| 
 | ||||
| <small>*(node-fetch extension)*</small> | ||||
| 
 | ||||
| * Returns: <code>Promise<String></code> | ||||
| 
 | ||||
| Identical to `body.text()`, except instead of always converting to UTF-8, encoding sniffing will be performed and text converted to UTF-8 if possible. | ||||
| 
 | ||||
| (This API requires an optional dependency of the npm package [encoding](https://www.npmjs.com/package/encoding), which you need to install manually. `webpack` users may see [a warning message](https://github.com/bitinn/node-fetch/issues/412#issuecomment-379007792) due to this optional dependency.) | ||||
| 
 | ||||
| <a id="class-fetcherror"></a> | ||||
| ### Class: FetchError | ||||
| 
 | ||||
| <small>*(node-fetch extension)*</small> | ||||
| 
 | ||||
| An operational error in the fetching process. See [ERROR-HANDLING.md][] for more info. | ||||
| 
 | ||||
| <a id="class-aborterror"></a> | ||||
| ### Class: AbortError | ||||
| 
 | ||||
| <small>*(node-fetch extension)*</small> | ||||
| 
 | ||||
| An Error thrown when the request is aborted in response to an `AbortSignal`'s `abort` event. It has a `name` property of `AbortError`. See [ERROR-HANDLING.MD][] for more info. | ||||
