 | 
			
		||||
## 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);
 | 
			
		||||
    });
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
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);
 | 
			
		||||
  });
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||

## 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`            | `*/*`
 | 
			
		||||
`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.
 | 
			
		||||
 | 
			
		||||
If no agent is specified, the default agent provided by Node.js is used. Note that [this changed in Node.js 19](https://github.com/nodejs/node/blob/4267b92604ad78584244488e7f7508a690cb80d0/lib/_http_agent.js#L564) to have `keepalive` true by default. If you wish to enable `keepalive` in an earlier version of Node.js, you can override the agent as per the following code sample. 
 | 
			
		||||
 | 
			
		||||
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.
 |
