## 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
|
||||
|
||||
- Enhance: more comprehensive API docs
|
||||
- Enhance: add a list of default headers in README
|
||||

|
||||
|
||||
## 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 --save
|
||||
```
|
||||
|
||||
## Loading and configuring the module
|
||||
We suggest you load the module via `require`, pending the stabalizing 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 `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.
|
||||
|
||||
Adding a catch to the fetch promise chain 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
|
||||
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 only cancel streamed requests 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 follows:
|
||||
|
||||
```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). 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` | `*/*`
|
||||
`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 that's out of the scope of Fetch. Including and not limit to:
|
||||
|
||||
- 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, `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]
|
||||
|
||||
The data 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 spec, 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 on 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.
