+
+## v2.6.0
+
+- Enhance: `options.agent`, it now accepts a function that returns custom http(s).Agent instance based on current URL, see readme for more information.

+
+## v2.1.0
+
+- Enhance: allow using ArrayBuffer as the `body` of a `fetch()` or `Request`

+- Fix: silently ignore invalid HTTP headers
+- Fix: handle HTTP redirect responses without a `Location` header just like non-redirect responses
+- Fix: include bodies when following a redirection when appropriate
+
+## v2.0.0
+
+This is a major release. 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 v4.x, v6.x, v8.x LTS, as well as v9.x stable
+- 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
+- Other: update package.json script for npm 5
+- Other: `encoding` module is now optional (alpha.7)
+- Other: expose browser.js through package.json, avoid bundling mishaps (alpha.9)
+- Other: allow TypeScript to `import` node-fetch by exposing default (alpha.9)
+
+### HTTP requests
+
+- Major: overwrite user's `Content-Length` if we can be sure our information is correct (per spec)
+- Fix: errors in a response are caught before the body is accessed
+- 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)
+- Enhance: `URLSearchParams` is now accepted as a body
+- Enhance: wrap `response.json()` json parsing error as `FetchError`
+- 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

+
+## 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&lt;[Response](#class-response)&gt;</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

+```
+
+##### 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&lt;Buffer&gt;</code>
+
+Consume the body and return a promise that will resolve to a Buffer.
+
+#### body.textConverted()
+
+<small>*(node-fetch extension)*</small>
+
+* Returns: <code>Promise&lt;String&gt;</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.
