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 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); + }); +``` + +In Node.js 14 you can also use async iterators to read `body`; however, be careful to catch +errors -- the longer a response runs, the more likely it is to encounter an error. + +```js +const fetch = require('node-fetch'); +const response = await fetch('https://httpbin.org/stream/3'); +try { + for await (const chunk of response.body) { + console.dir(JSON.parse(chunk.toString())); + } +} catch (err) { + console.error(err.stack); +} +``` + +In Node.js 12 you can also use async iterators to read `body`; however, async iterators with streams +did not mature until Node.js 14, so you need to do some extra work to ensure you handle errors +directly from the stream and wait on it response to fully close. + +```js +const fetch = require('node-fetch'); +const read = async body => { + let error; + body.on('error', err => { + error = err; + }); + for await (const chunk of body) { + console.dir(JSON.parse(chunk.toString())); + } + return new Promise((resolve, reject) => { + body.on('close', () => { + error ? reject(error) : resolve(); + }); + }); +}; +try { + const response = await fetch('https://httpbin.org/stream/3'); + await read(response.body); +} catch (err) { + console.error(err.stack); +} +``` + +#### 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).
