-Upgrading from 2x to 3x
- - Updating from 2 to 3 should be a breeze since there is not many changes to the blob specification. - The major cause of a major release is coding standards. - - internal WeakMaps was replaced with private fields - - internal Buffer.from was replaced with TextEncoder/Decoder - - internal buffers was replaced with Uint8Arrays - - CommonJS was replaced with ESM - - The node stream returned by calling `blob.stream()` was replaced with whatwg streams - - (Read "Differences from other blobs" for more info.) - -
-
-
-## Usage
-
-```js
-// Ways to import
-// (PS it's dependency free ESM package so regular http-import from CDN works too)
-import Blob from 'fetch-blob'
-import File from 'fetch-blob/file.js'
-
-import {Blob} from 'fetch-blob'
-import {File} from 'fetch-blob/file.js'
-
-const {Blob} = await import('fetch-blob')
-
-
-// Ways to read the blob:
-const blob = new Blob(['hello, world'])
-
-await blob.text()
-await blob.arrayBuffer()
-for await (let chunk of blob.stream()) { ... }
-blob.stream().getReader().read()
-blob.stream().getReader({mode: 'byob'}).read(view)
-```
-
-### Blob part backed up by filesystem
-
-`fetch-blob/from.js` comes packed with tools to convert any filepath into either a Blob or a File
-It will not read the content into memory. It will only stat the file for last modified date and file size.
-
-```js
-// The default export is sync and use fs.stat to retrieve size & last modified as a blob
-import blobFromSync from 'fetch-blob/from.js'
-import {File, Blob, blobFrom, blobFromSync, fileFrom, fileFromSync} from 'fetch-blob/from.js'
-
-const fsFile = fileFromSync('./2-GiB-file.bin', 'application/octet-stream')
-const fsBlob = await blobFrom('./2-GiB-file.mp4')
-
-// Not a 4 GiB memory snapshot, just holds references
-// points to where data is located on the disk
-const blob = new Blob([fsFile, fsBlob, 'memory', new Uint8Array(10)])
-console.log(blob.size) // ~4 GiB
-```
-
-`blobFrom|blobFromSync|fileFrom|fileFromSync(path, [mimetype])`
-
-### Creating Blobs backed up by other async sources
-Our Blob & File class are more generic then any other polyfills in the way that it can accept any blob look-a-like item
-An example of this is that our blob implementation can be constructed with parts coming from [BlobDataItem](https://github.com/node-fetch/fetch-blob/blob/8ef89adad40d255a3bbd55cf38b88597c1cd5480/from.js#L32) (aka a filepath) or from [buffer.Blob](https://nodejs.org/api/buffer.html#buffer_new_buffer_blob_sources_options), It dose not have to implement all the methods - just enough that it can be read/understood by our Blob implementation. The minium requirements is that it has `Symbol.toStringTag`, `size`, `slice()` and either a `stream()` or a `arrayBuffer()` method. If you then wrap it in our Blob or File `new Blob([blobDataItem])` then you get all of the other methods that should be implemented in a blob or file
-
-An example of this could be to create a file or blob like item coming from a remote HTTP request. Or from a DataBase
-
-See the [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/API/Blob) and [tests](https://github.com/node-fetch/fetch-blob/blob/master/test.js) for more details of how to use the Blob.

- - - Unlike NodeJS `buffer.Blob` (Added in: v15.7.0) and browser native Blob this polyfilled version can't be sent via PostMessage - - This blob version is more arbitrary, it can be constructed with blob parts that isn't a instance of itself - it has to look and behave as a blob to be accepted as a blob part. - - The benefit of this is that you can create other types of blobs that don't contain any internal data that has to be read in other ways, such as the `BlobDataItem` created in `from.js` that wraps a file path into a blob-like item and read lazily (nodejs plans to [implement this][fs-blobs] as well) - - The `blob.stream()` is the most noticeable differences. It returns a WHATWG stream now. to keep it as a node stream you would have to do: - - ```js - import {Readable} from 'stream' - const stream = Readable.from(blob.stream()) - ``` --But NodeJS still laks a proper FormData
The good old form-data package is a very old and isn't spec compatible and dose some abnormal stuff to construct and read FormData instances that other http libraries are not happy about when it comes to follow the spec. - -### The NodeJS / ESM version -- The modular (~2.3 KiB minified uncompressed) version of this package is independent of any browser stuff and don't patch anything -- It's as pure/spec compatible as it possible gets the test are run by WPT. -- It's compatible with [node-fetch](https://github.com/node-fetch/node-fetch). -- It have higher platform dependencies as it uses classes, symbols, ESM & private fields -- Only dependency it has is [fetch-blob](https://github.com/node-fetch/fetch-blob) - -```js -// Node example -import fetch from 'node-fetch' -import File from 'fetch-blob/file.js' -import { fileFromSync } from 'fetch-blob/from.js' -import { FormData } from 'formdata-polyfill/esm.min.js' - -const file = fileFromSync('./README.md') -const fd = new FormData() - -fd.append('file-upload', new File(['abc'], 'hello-world.txt')) -fd.append('file-upload', file) - -// it's also possible to append file/blob look-a-like items -// if you have streams coming from other destinations -fd.append('file-upload', { - size: 123, - type: '', - name: 'cat-video.mp4', - stream() { return stream }, - [Symbol.toStringTag]: 'File' -}) - -fetch('https://httpbin.org/post', { method: 'POST', body: fd }) -``` - ----- - -It also comes with way to convert FormData into Blobs - it's not something that every developer should have to deal with. -It's mainly for [node-fetch](https://github.com/node-fetch/node-fetch) and other http library to ease the process of serializing a FormData into a blob and just wish to deal with Blobs instead (Both Deno and Undici adapted a version of this [formDataToBlob](https://github.com/jimmywarting/FormData/blob/5ddea9e0de2fc5e246ab1b2f9d404dee0c319c02/formdata-to-blob.js) to the core and passes all WPT tests run by the browser itself) -```js -import { Readable } from 'node:stream' -import { FormData, formDataToBlob } from 'formdata-polyfill/esm.min.js' - -const blob = formDataToBlob(new FormData()) -fetch('https://httpbin.org/post', { method: 'POST', body: blob }) - -// node built in http and other similar http library have to do: -const stream = Readable.from(blob.stream()) -const req = http.request('http://httpbin.org/post', { - method: 'post', - headers: { - 'Content-Length': blob.size, - 'Content-Type': blob.type - } -}) -stream.pipe(req) -``` - -PS: blob & file that are appended to the FormData will not be read until any of the serialized blob read-methods gets called -...so uploading very large files is no biggie - -### Browser polyfill - -usage: - -```js -import 'formdata-polyfill' // that's it -``` - -The browser polyfill conditionally replaces the native implementation rather than fixing the missing functions, -since otherwise there is no way to get or delete existing values in the FormData object. -Therefore this also patches `XMLHttpRequest.prototype.send` and `fetch` to send the `FormData` as a blob, -and `navigator.sendBeacon` to send native `FormData`. - -I was unable to patch the Response/Request constructor -so if you are constructing them with FormData then you need to call `fd._blob()` manually. - -```js -new Request(url, { - method: 'post', - body: fd._blob ? fd._blob() : fd -}) -``` - -Dependencies ---- - -If you need to support IE <= 9 then I recommend you to include eligrey's [blob.js] -(which i hope you don't - since IE is now dead) - -

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.
+- Use native promise but allow substituting it with [insert your favorite promise library].
+- Use native Node streams for body on both request and response.

## Difference from client-side fetch
-- See known differences:
- - [As of v3.x](docs/v3-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.
+Current stable release (`2.x`)
```sh
-npm install node-fetch
+$ npm install node-fetch
```
## Loading and configuring the module
-
-### ES Modules (ESM)
-
+We suggest you load the module via `require` until the stabilization of ES modules in node:
```js
-import fetch from 'node-fetch';
+const fetch = require('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:
-
+If you are using a Promise library other than native, set it through `fetch.Promise`:
```js
-// mod.cjs
-const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args));
+const Bluebird = require('bluebird');
+
+fetch.Promise = Bluebird;
```
-### 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'
-
-// ...
-```
-

+#### 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, ...args) {
- super(`HTTP Error Response: ${response.status} ${response.statusText}`, ...args);
- this.response = response;
- }
+function checkStatus(res) {
+ if (res.ok) { // res.status >= 200 && res.status < 300
+ return res;
+ } else {
+ throw MyCustomError(res.statusText);
+ }
}
-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}`);
-}
+fetch('https://httpbin.org/status/400')
+ .then(checkStatus)
+ .then(res => console.log('will not get here...'))
```
-### 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.
+#### Streams
+The "Node.js way" is to use streams when possible:
```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'));
+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.
+#### Buffer
+If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API)
```js
-import fetch from 'node-fetch';
+const fileType = require('file-type');
-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);
-}
+fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
+ .then(res => res.buffer())
+ .then(buffer => fileType(buffer))
+ .then(type => { /* ... */ });
```
-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.
-
+#### Accessing Headers and other Meta data
```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);
-}
+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'));
+ });
```
-### 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
+#### 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']);
+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
+#### Post data using a file stream
```js
-import fetch {
- Blob,
- blobFrom,
- blobFromSync,
- File,
- fileFrom,
- fileFromSync,
-} from 'node-fetch'
+const { createReadStream } = require('fs');
-const mimetype = 'text/plain'
-const blob = fileFromSync('./input.txt', mimetype)
-const url = 'https://httpbin.org/post'
+const stream = createReadStream('input.txt');
-const response = await fetch(url, { method: 'POST', body: blob })
-const data = await response.json()
-
-console.log(data)
+fetch('https://httpbin.org/post', { method: 'POST', body: stream })
+ .then(res => res.json())
+ .then(json => console.log(json));
```
-node-fetch comes with a spec-compliant [FormData] implementations for posting
-multipart/form-data payloads
+#### Post with form-data (detect multipart)
```js
-import fetch, { FormData, File, fileFrom } from 'node-fetch'
+const FormData = require('form-data');
-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' })
+const form = new FormData();
+form.append('a', 1);
-formData.set('greeting', 'Hello, world!')
-formData.set('file-upload', abc, 'new name.txt')
+fetch('https://httpbin.org/post', { method: 'POST', body: form })
+ .then(res => res.json())
+ .then(json => console.log(json));
-const response = await fetch(httpbin, { method: 'POST', body: formData })
-const data = await response.json()
+// OR, using custom headers
+// NOTE: getHeaders() is non-standard API
-console.log(data)
+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));
```
-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.
+#### Request cancellation with AbortSignal
-The minium 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
+> 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 fetch, { AbortError } from 'node-fetch';
-
-// AbortController was added in node v14.17.0 globally
-const AbortController = globalThis.AbortController || await import('abort-controller')
+import AbortController from 'abort-controller';
const controller = new AbortController();
-const timeout = setTimeout(() => {
- controller.abort();
-}, 150);
+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);
-}
+fetch(url, { signal: controller.signal })
+ .then(res => res.json())
+ .then(
+ data => {
+ useData(data)
+ },
+ err => {
+ if (err.name === 'AbortError') {
+ // request was aborted
+ }
+ },
+ )
+ .finally(() => {
+ clearTimeout(timeout);
+ });

@@ -561,85 +364,25 @@ See [`http.Agent`](https://nodejs.org/api/http.html#http_new_agent_options) for
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
+ keepAlive: true
});
const httpsAgent = new https.Agent({

- 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

-
-The `redirect: 'manual'` option for node-fetch is different from the browser & specification, which

-node-fetch gives you the typical [basic filtered response](https://fetch.spec.whatwg.org/#concept-filtered-response-basic) instead.
