However, there are important differences between using the built-in fetch and installing undici as a separate module. + +### Built-in Fetch (Node.js v18+) + +Node.js's built-in fetch is powered by a bundled version of undici: + +```js +// Available globally in Node.js v18+ +const response = await fetch('https://api.example.com/data'); +const data = await response.json(); + +// Check the bundled undici version +console.log(process.versions.undici); // e.g., "5.28.4" +``` + +**Pros:** +- No additional dependencies required +- Works across different JavaScript runtimes +- Automatic compression handling (gzip, deflate, br) +- Built-in caching support (in development) + +**Cons:** +- Limited to the undici version bundled with your Node.js version +- Less control over connection pooling and advanced features +- Error handling follows Web API standards (errors wrapped in `TypeError`) +- Performance overhead due to Web Streams implementation + +### Undici Module + +Installing undici as a separate module gives you access to the latest features and APIs: + +```bash +npm install undici +``` + +```js +import { request, fetch, Agent, setGlobalDispatcher } from 'undici'; + +// Use undici.request for maximum performance +const { statusCode, headers, body } = await request('https://api.example.com/data'); +const data = await body.json(); + +// Or use undici.fetch with custom configuration +const agent = new Agent({ keepAliveTimeout: 10000 }); +setGlobalDispatcher(agent); +const response = await fetch('https://api.example.com/data'); +``` + +**Pros:** +- Latest undici features and bug fixes +- Access to advanced APIs (`request`, `stream`, `pipeline`) +- Fine-grained control over connection pooling +- Better error handling with clearer error messages +- Superior performance, especially with `undici.request` +- HTTP/1.1 pipelining support +- Custom interceptors and middleware +- Advanced features like `ProxyAgent`, `MockAgent` + +**Cons:** +- Additional dependency to manage +- Larger bundle size + +### When to Use Each + +#### Use Built-in Fetch When: +- You want zero dependencies +- Building isomorphic code that runs in browsers and Node.js +- Publishing to npm and want to maximize compatibility with JS runtimes +- Simple HTTP requests without advanced configuration +- You're publishing to npm and you want to maximize compatiblity +- You don't depend on features from a specific version of undici + +#### Use Undici Module When: +- You need the latest undici features and performance improvements +- You require advanced connection pooling configuration +- You need APIs not available in the built-in fetch (`ProxyAgent`, `MockAgent`, etc.) +- Performance is critical (use `undici.request` for maximum speed) +- You want better error handling and debugging capabilities +- You need HTTP/1.1 pipelining or advanced interceptors +- You prefer decoupled protocol and API interfaces + +### Performance Comparison + +Based on benchmarks, here's the typical performance hierarchy: + +1. **`undici.request()`** - Fastest, most efficient +2. **`undici.fetch()`** - Good performance, standard compliance +3. **Node.js `http`/`https`** - Baseline performance + +### Migration Guide + +If you're currently using built-in fetch and want to migrate to undici: + +```js +// Before: Built-in fetch +const response = await fetch('https://api.example.com/data'); + +// After: Undici fetch (drop-in replacement) +import { fetch } from 'undici'; +const response = await fetch('https://api.example.com/data'); + +// Or: Undici request (better performance) +import { request } from 'undici'; +const { statusCode, body } = await request('https://api.example.com/data'); +const data = await body.json(); +``` + +### Version Compatibility + +You can check which version of undici is bundled with your Node.js version: + +```js +console.log(process.versions.undici); +``` + +Installing undici as a module allows you to use a newer version than what's bundled with Node.js, giving you access to the latest features and performance improvements. + +## Quick Start + +```js +import { request } from 'undici' + +const { + statusCode, + headers, + trailers, + body +} = await request('http://localhost:3000/foo') + +console.log('response received', statusCode) +console.log('headers', headers) + +for await (const data of body) { console.log('data', data) } + +console.log('trailers', trailers) +``` + +## Global Installation + +Undici provides an `install()` function to add all WHATWG fetch classes to `globalThis`, making them available globally: + +```js +import { install } from 'undici' + +// Install all WHATWG fetch classes globally +install() + +// Now you can use fetch classes globally without importing +const response = await fetch('https://api.example.com/data') +const data = await response.json() + +// All classes are available globally: +const headers = new Headers([['content-type', 'application/json']]) +const request = new Request('https://example.com') +const formData = new FormData() +const ws = new WebSocket('wss://example.com') +const eventSource = new EventSource('https://example.com/events') +``` + +The `install()` function adds the following classes to `globalThis`: + +- `fetch` - The fetch function +- `Headers` - HTTP headers management +- `Response` - HTTP response representation +- `Request` - HTTP request representation +- `FormData` - Form data handling +- `WebSocket` - WebSocket client +- `CloseEvent`, `ErrorEvent`, `MessageEvent` - WebSocket events +- `EventSource` - Server-sent events client + +This is useful for: +- Polyfilling environments that don't have fetch +- Ensuring consistent fetch behavior across different Node.js versions +- Making undici's implementations available globally for libraries that expect them + +## Body Mixins + +The `body` mixins are the most common way to format the request/response body. Mixins include: + +- [`.arrayBuffer()`](https://fetch.spec.whatwg.org/#dom-body-arraybuffer) +- [`.blob()`](https://fetch.spec.whatwg.org/#dom-body-blob) +- [`.bytes()`](https://fetch.spec.whatwg.org/#dom-body-bytes) +- [`.json()`](https://fetch.spec.whatwg.org/#dom-body-json) +- [`.text()`](https://fetch.spec.whatwg.org/#dom-body-text) + +> [!NOTE] +> The body returned from `undici.request` does not implement `.formData()`. + +Example usage: + +```js +import { request } from 'undici' + +const { + statusCode, + headers, + trailers, + body +} = await request('http://localhost:3000/foo') + +console.log('response received', statusCode) +console.log('headers', headers) +console.log('data', await body.json()) +console.log('trailers', trailers) +``` + +_Note: Once a mixin has been called then the body cannot be reused, thus calling additional mixins on `.body`, e.g. `.body.json(); .body.text()` will result in an error `TypeError: unusable` being thrown and returned through the `Promise` rejection._ + +Should you need to access the `body` in plain-text after using a mixin, the best practice is to use the `.text()` mixin first and then manually parse the text to the desired format. + +For more information about their behavior, please reference the body mixin from the [Fetch Standard](https://fetch.spec.whatwg.org/#body-mixin). + +## Common API Methods + +This section documents our most commonly used API methods.

It is not present in the [Fetch Standard](https://fetch.spec.whatwg.org). + +```js +import { fetch } from 'undici' + +const data = { + async *[Symbol.asyncIterator]() { + yield 'hello' + yield 'world' + }, +} + +await fetch('https://example.com', { body: data, method: 'POST', duplex: 'half' }) +``` + +[FormData](https://developer.mozilla.org/en-US/docs/Web/API/FormData) besides text data and buffers can also utilize streams via [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) objects: + +```js +import { openAsBlob } from 'node:fs' + +const file = await openAsBlob('./big.csv') +const body = new FormData() +body.set('file', file, 'big.csv') + +await fetch('http://example.com', { method: 'POST', body }) +``` + +#### `request.duplex` + +- `'half'` + +In this implementation of fetch, `request.duplex` must be set if `request.body` is `ReadableStream` or `Async Iterables`, however, even though the value must be set to `'half'`, it is actually a _full_ duplex. For more detail refer to the [Fetch Standard](https://fetch.spec.whatwg.org/#dom-requestinit-duplex). + +#### `response.body` + +Nodejs has two kinds of streams: [web streams](https://nodejs.org/api/webstreams.html), which follow the API of the WHATWG web standard found in browsers, and an older Node-specific [streams API](https://nodejs.org/api/stream.html). `response.body` returns a readable web stream. If you would prefer to work with a Node stream you can convert a web stream using `.fromWeb()`. + +```js +import { fetch } from 'undici' +import { Readable } from 'node:stream' + +const response = await fetch('https://example.com') +const readableWebStream = response.body +const readableNodeStream = Readable.fromWeb(readableWebStream) +``` + +## Specification Compliance + +This section documents parts of the [HTTP/1.1](https://www.rfc-editor.org/rfc/rfc9110.html) and [Fetch Standard](https://fetch.spec.whatwg.org) that Undici does +not support or does not fully implement. + +#### CORS + +Unlike browsers, Undici does not implement CORS (Cross-Origin Resource Sharing) checks by default. This means: + +- No preflight requests are automatically sent for cross-origin requests +- No validation of `Access-Control-Allow-Origin` headers is performed +- Requests to any origin are allowed regardless of the source + +This behavior is intentional for server-side environments where CORS restrictions are typically unnecessary. If your application requires CORS-like protections, you will need to implement these checks manually. + +#### Garbage Collection + +* https://fetch.spec.whatwg.org/#garbage-collection + +The [Fetch Standard](https://fetch.spec.whatwg.org) allows users to skip consuming the response body by relying on +[garbage collection](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Memory_Management#garbage_collection) to release connection resources. + +Garbage collection in Node is less aggressive and deterministic +(due to the lack of clear idle periods that browsers have through the rendering refresh rate) +which means that leaving the release of connection resources to the garbage collector can lead +to excessive connection usage, reduced performance (due to less connection re-use), and even +stalls or deadlocks when running out of connections. +Therefore, __it is important to always either consume or cancel the response body anyway__. + +```js +// Do +const { body, headers } = await fetch(url); +for await (const chunk of body) { + // force consumption of body +} + +// Do not +const { headers } = await fetch(url); +``` + +However, if you want to get only headers, it might be better to use `HEAD` request method. Usage of this method will obviate the need for consumption or cancelling of the response body. See [MDN - HTTP - HTTP request methods - HEAD](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/HEAD) for more details. + +```js +const headers = await fetch(url, { method: 'HEAD' }) + .then(res => res.headers) +``` + +Note that consuming the response body is _mandatory_ for `request`: + +```js +// Do +const { body, headers } = await request(url); +await res.body.dump(); // force consumption of body + +// Do not +const { headers } = await request(url); +``` + +#### Forbidden and Safelisted Header Names + +* https://fetch.spec.whatwg.org/#cors-safelisted-response-header-name +* https://fetch.spec.whatwg.org/#forbidden-header-name +* https://fetch.spec.whatwg.org/#forbidden-response-header-name +* https://github.com/wintercg/fetch/issues/6 + +The [Fetch Standard](https://fetch.spec.whatwg.org) requires implementations to exclude certain headers from requests and responses.

While an `origin` is required for instantiating a `Client` instance, the underlying socket connection will not be established until a request is queued using [`Client.dispatch()`](/docs/docs/api/Client.md#clientdispatchoptions-handlers). By calling `Client.dispatch()` directly or using one of the multiple implementations ([`Client.connect()`](Client.md#clientconnectoptions-callback), [`Client.pipeline()`](Client.md#clientpipelineoptions-handler), [`Client.request()`](Client.md#clientrequestoptions-callback), [`Client.stream()`](Client.md#clientstreamoptions-factory-callback), and [`Client.upgrade()`](/docs/docs/api/Client.md#clientupgradeoptions-callback)), the `Client` instance will transition from **idle** to [**pending**](/docs/docs/api/Client.md#pending) and then most likely directly to [**processing**](/docs/docs/api/Client.md#processing). + +Calling [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) or [`Client.destroy()`](Client.md#clientdestroyerror-callback) transitions directly to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state since the `Client` instance will have no queued requests in this state. + +### pending + +The **pending** state signifies a non-processing `Client`. Upon entering this state, the `Client` establishes a socket connection and emits the [`'connect'`](/docs/docs/api/Client.md#event-connect) event signalling a connection was successfully established with the `origin` provided during `Client` instantiation. The internal queue is initially empty, and requests can start queueing. + +Calling [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) with queued requests, transitions the `Client` to the [**processing**](/docs/docs/api/Client.md#processing) state. Without queued requests, it transitions to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state. + +Calling [`Client.destroy()`](/docs/docs/api/Client.md#clientdestroyerror-callback) transitions directly to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state regardless of existing requests. + +### processing + +The **processing** state is a state machine within itself. It initializes to the [**processing.running**](/docs/docs/api/Client.md#running) state. The [`Client.dispatch()`](/docs/docs/api/Client.md#clientdispatchoptions-handlers), [`Client.close()`](Client.md#clientclosecallback), and [`Client.destroy()`](Client.md#clientdestroyerror-callback) can be called at any time while the `Client` is in this state. `Client.dispatch()` will add more requests to the queue while existing requests continue to be processed. `Client.close()` will transition to the [**processing.closing**](/docs/docs/api/Client.md#closing) state. And `Client.destroy()` will transition to [**destroyed**](/docs/docs/api/Client.md#destroyed). + +#### running + +In the **processing.running** sub-state, queued requests are being processed in a FIFO order. If a request body requires draining, the *needDrain* event transitions to the [**processing.busy**](/docs/docs/api/Client.md#busy) sub-state. The *close* event transitions the Client to the [**process.closing**](/docs/docs/api/Client.md#closing) sub-state. If all queued requests are processed and neither [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) nor [`Client.destroy()`](Client.md#clientdestroyerror-callback) are called, then the [**processing**](/docs/docs/api/Client.md#processing) machine will trigger a *keepalive* event transitioning the `Client` back to the [**pending**](/docs/docs/api/Client.md#pending) state. During this time, the `Client` is waiting for the socket connection to timeout, and once it does, it triggers the *timeout* event and transitions to the [**idle**](/docs/docs/api/Client.md#idle) state. + +#### busy + +This sub-state is only entered when a request body is an instance of [Stream](https://nodejs.org/api/stream.html) and requires draining. The `Client` cannot process additional requests while in this state and must wait until the currently processing request body is completely drained before transitioning back to [**processing.running**](/docs/docs/api/Client.md#running). + +#### closing + +This sub-state is only entered when a `Client` instance has queued requests and the [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) method is called. In this state, the `Client` instance continues to process requests as usual, with the one exception that no additional requests can be queued. Once all of the queued requests are processed, the `Client` will trigger the *done* event gracefully entering the [**destroyed**](/docs/docs/api/Client.md#destroyed) state without an error. + +### destroyed + +The **destroyed** state is a final state for the `Client` instance. Once in this state, a `Client` is nonfunctional.
