+
+## 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 Jason Miller's [isomorphic-unfetch](https://www.npmjs.com/package/isomorphic-unfetch) 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 and async functions.
+- Use native Node streams for body, on both request and response.
+- Decode content encoding (gzip/deflate/brotli) properly, and convert string output (such as `res.text()` and `res.json()`) to UTF-8 automatically.
+- Useful extensions such as redirect limit, response size limit, [explicit errors][error-handling.md] for troubleshooting.
+
+## Difference from client-side fetch
+
+- See known differences:
+ - [As of v3.x](docs/v3-LIMITS.md)
+ - [As of v2.x](docs/v2-LIMITS.md)
+- 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 (`3.x`) requires at least Node.js 12.20.0.
+
+```sh
+npm install node-fetch
+```
+
+## Loading and configuring the module
+
+### ES Modules (ESM)
+
+```js
+import fetch from 'node-fetch';
+```
+
+### CommonJS
+
+`node-fetch` from v3 is an ESM-only module - you are not able to import it with `require()`.
+
+If you cannot switch to ESM, please use v2 which remains compatible with CommonJS. Critical bug fixes will continue to be published for v2.
+
+```sh
+npm install node-fetch@2
+```
+
+Alternatively, you can use the async `import()` function from CommonJS to load `node-fetch` asynchronously:
+
+```js
+// mod.cjs
+const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args));
+```
+
+### Providing global access
+
+To use `fetch()` without importing it, you can patch the `global` object in node:
+
+```js
+// fetch-polyfill.js
+import fetch, {
+ Blob,
+ blobFrom,
+ blobFromSync,
+ File,
+ fileFrom,
+ fileFromSync,
+ FormData,
+ Headers,
+ Request,
+ Response,
+} from 'node-fetch'
+
+if (!globalThis.fetch) {
+ globalThis.fetch = fetch
+ globalThis.Headers = Headers
+ globalThis.Request = Request
+ globalThis.Response = Response
+}
+
+// index.js
+import './fetch-polyfill'
+
+// ...
+```
+
+## Upgrading
+
+Using an old version of node-fetch? Check out the following files:
+
+- [2.x to 3.x upgrade guide](docs/v3-UPGRADE-GUIDE.md)
+- [1.x to 2.x upgrade guide](docs/v2-UPGRADE-GUIDE.md)
+- [Changelog](https://github.com/node-fetch/node-fetch/releases)
+
+## Common Usage
+
+NOTE: The documentation below is up-to-date with `3.x` releases, if you are using an older version, please check how to [upgrade](#upgrading).
+
+### Plain text or HTML
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://github.com/');
+const body = await response.text();
+
+console.log(body);
+```
+
+### JSON
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://api.github.com/users/github');
+const data = await response.json();
+
+console.log(data);
+```
+
+### Simple Post
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://httpbin.org/post', {method: 'POST', body: 'a=1'});
+const data = await response.json();
+
+console.log(data);
+```
+
+### Post with JSON
+
+```js
+import fetch from 'node-fetch';
+
+const body = {a: 1};
+
+const response = await fetch('https://httpbin.org/post', {
+ method: 'post',
+ body: JSON.stringify(body),
+ headers: {'Content-Type': 'application/json'}
+});
+const data = await response.json();
+
+console.log(data);
+```
+
+### Post with form parameters
+
+`URLSearchParams` is available on the global object in Node.js as of v10.0.0. 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
+import fetch from 'node-fetch';
+
+const params = new URLSearchParams();
+params.append('a', 1);
+
+const response = await fetch('https://httpbin.org/post', {method: 'POST', body: params});
+const data = await response.json();
+
+console.log(data);
+```
+
+### Handling exceptions
+
+NOTE: 3xx-5xx responses are _NOT_ exceptions, and should be handled in `then()`, see the next section.
+
+Wrapping the fetch function into a `try/catch` block will catch _all_ exceptions, such as errors originating from node core libraries, like network errors, and operational errors which are instances of FetchError. See the [error handling document][error-handling.md] for more details.
+
+```js
+import fetch from 'node-fetch';
+
+try {
+ await fetch('https://domain.invalid/');
+} catch (error) {
+ console.log(error);
+}
+```
+
+### 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
+import fetch from 'node-fetch';
+
+class HTTPResponseError extends Error {
+ constructor(response) {
+ super(`HTTP Error Response: ${response.status} ${response.statusText}`);
+ this.response = response;
+ }
+}
+
+const checkStatus = response => {
+ if (response.ok) {
+ // response.status >= 200 && response.status < 300
+ return response;
+ } else {
+ throw new HTTPResponseError(response);
+ }
+}
+
+const response = await fetch('https://httpbin.org/status/400');
+
+try {
+ checkStatus(response);
+} catch (error) {
+ console.error(error);
+
+ const errorBody = await error.response.text();
+ console.error(`Error body: ${errorBody}`);
+}
+```
+
+### Handling cookies
+
+Cookies are not stored by default. However, cookies can be extracted and passed by manipulating request and response headers. See [Extract Set-Cookie Header](#extract-set-cookie-header) for details.
+
+## Advanced Usage
+
+### Streams
+
+The "Node.js way" is to use streams when possible. You can pipe `res.body` to another stream. This example uses [stream.pipeline](https://nodejs.org/api/stream.html#stream_stream_pipeline_streams_callback) to attach stream error handlers and wait for the download to complete.
+
+```js
+import {createWriteStream} from 'node:fs';
+import {pipeline} from 'node:stream';
+import {promisify} from 'node:util'
+import fetch from 'node-fetch';
+
+const streamPipeline = promisify(pipeline);
+
+const response = await fetch('https://github.githubassets.com/images/modules/logos_page/Octocat.png');
+
+if (!response.ok) throw new Error(`unexpected response ${response.statusText}`);
+
+await streamPipeline(response.body, createWriteStream('./octocat.png'));
+```
+
+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
+import fetch from '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
+import fetch from '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);
+}
+```
+
+### Accessing Headers and other Metadata
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://github.com/');
+
+console.log(response.ok);
+console.log(response.status);
+console.log(response.statusText);
+console.log(response.headers.raw());
+console.log(response.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
+import fetch from 'node-fetch';
+
+const response = await fetch('https://example.com');
+
+// Returns an array of values, instead of a string of comma-separated values
+console.log(response.headers.raw()['set-cookie']);
+```
+
+### Post data using a file
+
+```js
+import fetch, {
+ Blob,
+ blobFrom,
+ blobFromSync,
+ File,
+ fileFrom,
+ fileFromSync,
+} from 'node-fetch'
+
+const mimetype = 'text/plain'
+const blob = fileFromSync('./input.txt', mimetype)
+const url = 'https://httpbin.org/post'
+
+const response = await fetch(url, { method: 'POST', body: blob })
+const data = await response.json()
+
+console.log(data)
+```
+
+node-fetch comes with a spec-compliant [FormData] implementations for posting
+multipart/form-data payloads
+
+```js
+import fetch, { FormData, File, fileFrom } from 'node-fetch'
+
+const httpbin = 'https://httpbin.org/post'
+const formData = new FormData()
+const binary = new Uint8Array([ 97, 98, 99 ])
+const abc = new File([binary], 'abc.txt', { type: 'text/plain' })
+
+formData.set('greeting', 'Hello, world!')
+formData.set('file-upload', abc, 'new name.txt')
+
+const response = await fetch(httpbin, { method: 'POST', body: formData })
+const data = await response.json()
+
+console.log(data)
+```
+
+If you for some reason need to post a stream coming from any arbitrary place,
+then you can append a [Blob] or a [File] look-a-like item.
+
+The minimum requirement is that it has:
+1. A `Symbol.toStringTag` getter or property that is either `Blob` or `File`
+2. A known size.
+3. And either a `stream()` method or a `arrayBuffer()` method that returns a ArrayBuffer.
+
+The `stream()` must return any async iterable object as long as it yields Uint8Array (or Buffer)
+so Node.Readable streams and whatwg streams works just fine.
+
+```js
+formData.append('upload', {
+ [Symbol.toStringTag]: 'Blob',
+ size: 3,
+ *stream() {
+ yield new Uint8Array([97, 98, 99])
+ },
+ arrayBuffer() {
+ return new Uint8Array([97, 98, 99]).buffer
+ }
+}, 'abc.txt')
+```
+
+### Request cancellation with AbortSignal
+
+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 fetch, { AbortError } from 'node-fetch';
+
+// AbortController was added in node v14.17.0 globally
+const AbortController = globalThis.AbortController || await import('abort-controller')
+
+const controller = new AbortController();
+const timeout = setTimeout(() => {
+ controller.abort();
+}, 150);
+
+try {
+ const response = await fetch('https://example.com', {signal: controller.signal});
+ const data = await response.json();
+} catch (error) {
+ if (error instanceof AbortError) {
+ console.log('request was aborted');
+ }
+} finally {
+ clearTimeout(timeout);
+}
+```
+
+See [test cases](https://github.com/node-fetch/node-fetch/blob/master/test/) 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:
+ +
A light-weight module that brings Fetch API to Node.js.
+
+
+
+
+
+ +
+ Consider supporting us on our Open Collective: +
+
+
+Promise<[Response](#class-response)>
+
+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`.
+
+
+
+### 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, 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
+ 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)
+ highWaterMark: 16384, // the maximum number of bytes to store in the internal buffer before ceasing to read from the underlying resource.
+ insecureHTTPParser: false // Use an insecure HTTP parser that accepts invalid HTTP headers when `true`.
+}
+```
+
+#### Default Headers
+
+If no values are set, the following request headers will be sent automatically:
+
+| Header | Value |
+| ------------------- | ------------------------------------------------------ |
+| `Accept-Encoding` | `gzip, deflate, br` (when `options.compress === true`) |
+| `Accept` | `*/*` |
+| `Content-Length` | _(automatically calculated, if possible)_ |
+| `Host` | _(host and port information from the target URI)_ |
+| `Transfer-Encoding` | `chunked` _(when `req.body` is a stream)_ |
+| `User-Agent` | `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
+import http from 'node:http';
+import https from 'node:https';
+
+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;
+ }
+ }
+};
+```
+
+
+
+#### Custom highWaterMark
+
+Stream on Node.js have a smaller internal buffer size (16kB, aka `highWaterMark`) from client-side browsers (>1MB, not consistent across browsers). Because of that, when you are writing an isomorphic app and using `res.clone()`, it will hang with large response in Node.
+
+The recommended way to fix this problem is to resolve cloned response in parallel:
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://example.com');
+const r1 = response.clone();
+
+const results = await Promise.all([response.json(), r1.text()]);
+
+console.log(results[0]);
+console.log(results[1]);
+```
+
+If for some reason you don't like the solution above, since `3.x` you are able to modify the `highWaterMark` option:
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://example.com', {
+ // About 1MB
+ highWaterMark: 1024 * 1024
+});
+
+const result = await res.clone().arrayBuffer();
+console.dir(result);
+```
+
+#### Insecure HTTP Parser
+
+Passed through to the `insecureHTTPParser` option on http(s).request. See [`http.request`](https://nodejs.org/api/http.html#http_http_request_url_options_callback) for more information.
+
+#### Manual Redirect
+
+The `redirect: 'manual'` option for node-fetch is different from the browser & specification, which
+results in an [opaque-redirect filtered response](https://fetch.spec.whatwg.org/#concept-filtered-response-opaque-redirect).
+node-fetch gives you the typical [basic filtered response](https://fetch.spec.whatwg.org/#concept-filtered-response-basic) instead.
+
+```js
+import fetch from 'node-fetch';
+
+const response = await fetch('https://httpbin.org/status/301', { redirect: 'manual' });
+
+if (response.status === 301 || response.status === 302) {
+ const locationURL = new URL(response.headers.get('location'), response.url);
+ const response2 = await fetch(locationURL, { redirect: 'manual' });
+ console.dir(response2);
+}
+```
+
+
+
+### 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`
+- `mode`
+- `credentials`
+- `cache`
+- `integrity`
+- `keepalive`
+
+The following node-fetch extension properties are provided:
+
+- `follow`
+- `compress`
+- `counter`
+- `agent`
+- `highWaterMark`
+
+See [options](#fetch-options) for exact meaning of these extensions.
+
+#### new Request(input[, options])
+
+_(spec-compliant)_
+
+- `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.
+
+
+
+### 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:
+
+- `trailer`
+
+#### new Response([body[, options]])
+
+_(spec-compliant)_
+
+- `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
+
+_(spec-compliant)_
+
+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
+
+_(spec-compliant)_
+
+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.
+
+#### response.type
+
+_(deviation from spec)_
+
+Convenience property representing the response's type. node-fetch only supports `'default'` and `'error'` and does not make use of [filtered responses](https://fetch.spec.whatwg.org/#concept-filtered-response).
+
+
+
+### 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])
+
+_(spec-compliant)_
+
+- `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
+import {Headers} from 'node-fetch';
+
+const meta = {
+ 'Content-Type': 'text/xml'
+};
+const headers = new Headers(meta);
+
+// The above is equivalent to
+const meta = [['Content-Type', 'text/xml']];
+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');
+const headers = new Headers(meta);
+const copyOfHeaders = new Headers(headers);
+```
+
+
+
+### Interface: Body
+
+`Body` is an abstract interface with methods that are applicable to both `Request` and `Response` classes.
+
+#### body.body
+
+_(deviation from spec)_
+
+- 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
+
+_(spec-compliant)_
+
+- `Boolean`
+
+A boolean property for if this body has been consumed. Per the specs, a consumed body cannot be used again.
+
+#### body.arrayBuffer()
+
+#### body.formData()
+
+#### body.blob()
+
+#### body.json()
+
+#### body.text()
+
+`fetch` comes with methods to parse `multipart/form-data` payloads as well as
+`x-www-form-urlencoded` bodies using `.formData()` this comes from the idea that
+Service Worker can intercept such messages before it's sent to the server to
+alter them. This is useful for anybody building a server so you can use it to
+parse & consume payloads.
+
+
+
+
+
+
+### Class: FetchError
+
+_(node-fetch extension)_
+
+An operational error in the fetching process. See [ERROR-HANDLING.md][] for more info.
+
+
+
+### Class: AbortError
+
+_(node-fetch extension)_
+
+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.
+
+## TypeScript
+
+**Since `3.x` types are bundled with `node-fetch`, so you don't need to install any additional packages.**
+
+For older versions please use the type definitions from [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped):
+
+```sh
+npm install --save-dev @types/node-fetch@2.x
+```
