Check [our upgrade guide](https://github.com/bitinn/node-fetch/blob/master/UPGRADE-GUIDE.md) for an overview on some key differences between v1 and v2. ### General changes - Major: Node.js 0.10.x and 0.12.x support is dropped - Major: `require('node-fetch/lib/response')` etc. is now unsupported; use `require('node-fetch').Response` or ES6 module imports - Enhance: start testing on Node.js 4, 6, 7 - Enhance: use Rollup to produce a distributed bundle (less memory overhead and faster startup) - Enhance: make `Object.prototype.toString()` on Headers, Requests, and Responses return correct class strings - Other: rewrite in ES2015 using Babel - Other: use Codecov for code coverage tracking ### HTTP requests - Major: overwrite user's `Content-Length` if we can be sure our information is correct (per spec) - Fix: support WHATWG URL objects, created by `whatwg-url` package or `require('url').URL` in Node.js 7+ ### Response and Request classes - Major: `response.text()` no longer attempts to detect encoding, instead always opting for UTF-8 (per spec); use `response.textConverted()` for the v1 behavior - Major: make `response.json()` throw error instead of returning an empty object on 204 no-content respose (per spec; reverts behavior changed in v1.6.2) - Major: internal methods are no longer exposed - Major: throw error when a `GET` or `HEAD` Request is constructed with a non-null body (per spec) - Enhance: add `response.arrayBuffer()` (also applies to Requests) - Enhance: add experimental `response.blob()` (also applies to Requests) - Fix: fix Request and Response with `null` body ### Headers class - Major: remove `headers.getAll()`; make `get()` return all headers delimited by commas (per spec) - Enhance: make Headers iterable - Enhance: make Headers constructor accept an array of tuples - Enhance: make sure header names and values are valid in HTTP - Fix: coerce Headers prototype function parameters to strings, where applicable ### Documentation - Enhance: more comprehensive API docs - Enhance: add a list of default headers in README # 1.x release ## v1.6.3 - Enhance: error handling document to explain `FetchError` design - Fix: support `form-data` 2.x releases (requires `form-data` >= 2.1.0) ## v1.6.2 - Enhance: minor document update - Fix: response.json() returns empty object on 204 no-content response instead of throwing a syntax error ## v1.6.1 - Fix: if `res.body` is a non-stream non-formdata object, we will call `body.toString` and send it as a string - Fix: `counter` value is incorrectly set to `follow` value when wrapping Request instance - Fix: documentation update ## v1.6.0 - Enhance: added `res.buffer()` api for convenience, it returns body as a Node.js buffer - Enhance: better old server support by handling raw deflate response - Enhance: skip encoding detection for non-HTML/XML response - Enhance: minor document update - Fix: HEAD request doesn't need decompression, as body is empty - Fix: `req.body` now accepts a Node.js buffer ## v1.5.3 - Fix: handle 204 and 304 responses when body is empty but content-encoding is gzip/deflate - Fix: allow resolving response and cloned response in any order - Fix: avoid setting `content-length` when `form-data` body use streams - Fix: send DELETE request with content-length when body is present - Fix: allow any url when calling new Request, but still reject non-http(s) url in fetch ## v1.5.2 - Fix: allow node.js core to handle keep-alive connection pool when passing a custom agent ## v1.5.1 - Fix: redirect mode `manual` should work even when there is no redirection or broken redirection ## v1.5.0 - Enhance: rejected promise now use custom `Error` (thx to @pekeler) - Enhance: `FetchError` contains `err.type` and `err.code`, allows for better error handling (thx to @pekeler) - Enhance: basic support for redirect mode `manual` and `error`, allows for location header extraction (thx to @jimmywarting for the initial PR) ## v1.4.1 - Fix: wrapping Request instance with FormData body again should preserve the body as-is ## v1.4.0 - Enhance: Request and Response now have `clone` method (thx to @kirill-konshin for the initial PR) - Enhance: Request and Response now have proper string and buffer body support (thx to @kirill-konshin) - Enhance: Body constructor has been refactored out (thx to @kirill-konshin) - Enhance: Headers now has `forEach` method (thx to @tricoder42) - Enhance: back to 100% code coverage - Fix: better form-data support (thx to @item4) - Fix: better character encoding detection under chunked encoding (thx to @dsuket for the initial PR) ## v1.3.3 - Fix: make sure `Content-Length` header is set when body is string for POST/PUT/PATCH requests - Fix: handle body stream error, for cases such as incorrect `Content-Encoding` header - Fix: when following certain redirects, use `GET` on subsequent request per Fetch Spec - Fix: `Request` and `Response` constructors now parse headers input using `Headers` ## v1.3.2 - Enhance: allow auto detect of form-data input (no `FormData` spec on node.js, this is form-data specific feature) ## v1.3.1 - Enhance: allow custom host header to be set (server-side only feature, as it's a forbidden header on client-side) ## v1.3.0 - Enhance: now `fetch.Request` is exposed as well ## v1.2.1 - Enhance: `Headers` now normalized `Number` value to `String`, prevent common mistakes ## v1.2.0 - Enhance: now fetch.Headers and fetch.Response are exposed, making testing easier ## v1.1.2 -

It has more regular releases and accepts some patches that would not fit with `node-fetch`'s own design goals (such as picking a specific cookie library, removing `babel` dependency altogether, etc). This library is *not a replacement* for `node-fetch`, nor does it intend to supplant it. It's purely a fork maintained for the sake of easier patching of specific needs that it wouldn't be fair to shove down the main project's throat. This project will still send patches for shared bugs over and hopefully help improve its "parent". ## 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) 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 difference. - Use native promise, but allow substituting it with [insert your favorite promise library]. - Use native stream 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][] for troubleshooting. ## Difference from client-side fetch - See [Known Differences](https://github.com/npm/node-fetch-npm/blob/master/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! ## Install ```sh $ npm install node-fetch-npm --save ``` ## Usage ```javascript import fetch from 'node-fetch'; // or // const fetch = require('node-fetch'); // if you are using your own Promise library, set it through fetch.Promise. Eg. // import Bluebird from 'bluebird'; // fetch.Promise = Bluebird; // plain text or html fetch('https://github.com/') .then(res => res.text()) .then(body => console.log(body)); // json fetch('https://api.github.com/users/github') .then(res => res.json()) .then(json => console.log(json)); // catching network error // 3xx-5xx responses are NOT network errors, and should be handled in then() // you only need one catch() at the end of your promise chain fetch('http://domain.invalid/') .catch(err => console.error(err)); // stream // the node.js way is to use stream when possible 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 that buffer() is a node-fetch only API import fileType from 'file-type'; fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') .then(res => res.buffer()) .then(buffer => fileType(buffer)) .then(type => { /* ... */ }); // meta 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')); }); // post fetch('http://httpbin.org/post', { method: 'POST', body: 'a=1' }) .then(res => res.json()) .then(json => console.log(json)); // post with stream from file import { createReadStream } from 'fs'; const stream = createReadStream('input.txt'); fetch('http://httpbin.org/post', { method: 'POST', body: stream }) .then(res => res.json()) .then(json => console.log(json)); // post with JSON var body = { a: 1 }; fetch('http://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-data (detect multipart) import FormData from 'form-data'; const form = new FormData(); form.append('a', 1); fetch('http://httpbin.org/post', { method: 'POST', body: form }) .then(res => res.json()) .then(json => console.log(json)); // post with form-data (custom headers) // note that getHeaders() is non-standard API import FormData from 'form-data'; const form = new FormData(); form.append('a', 1); fetch('http://httpbin.org/post', { method: 'POST', body: form, headers: form.getHeaders() }) .then(res => res.json()) .then(json => console.log(json)); // node 7+ with async function (async function () { const res = await fetch('https://api.github.com/users/github'); const json = await res.json(); console.log(json); })(); ``` See [test cases](https://github.com/npm/node-fetch-npm/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 `http://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 // The following properties are node-fetch-npm 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) 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, allows custom proxy, certificate etc. } ``` ##### 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)_ `User-Agent` | `node-fetch-npm/1.0 (+https://github.com/npm/node-fetch-npm)` <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-npm 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-npm at this moment: - `Response.error()` - `Response.redirect()` - `type` - `redirected` - `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. <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-npm at this moment: - `formData()` #### body.body <small>*(deviation from spec)*</small> * Node.js [`Readable` stream][node-readable] The data 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-npm 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 spec, 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-npm 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-npm 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. <a id="class-fetcherror"></a> ### Class: FetchError <small>*(node-fetch-npm extension)*</small> An operational error in the fetching process. See [ERROR-HANDLING.md][] for more info. ## License MIT ## Acknowledgement Thanks to [github/fetch](https://github.com/github/fetch) for providing a solid implementation reference.
