# Class: WebSocket
|
|
|
|
> ⚠️ Warning: the WebSocket API is experimental.
|
|
|
|
Extends: [`EventTarget`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget)
|
|
|
|
The WebSocket object provides a way to manage a WebSocket connection to a server, allowing bidirectional communication. The API follows the [WebSocket spec](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) and [RFC 6455](https://datatracker.ietf.org/doc/html/rfc6455).
|
|
|
|
## `new WebSocket(url[, protocol])`
|
|
|
|
Arguments:
|
|
|
|
* **url** `URL | string` - The url's protocol *must* be `ws` or `wss`.
|
|
* **protocol** `string | string[] | WebSocketInit` (optional) - Subprotocol(s) to request the server use, or a [`Dispatcher`](./Dispatcher.md).
|
|
|
|
### Example:
|
|
|
|
This example will not work in browsers or other platforms that don't allow passing an object.
|
|
|
|
```mjs
|
|
import { WebSocket, ProxyAgent } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
|
|
const ws = new WebSocket('wss://echo.websocket.events', {
|
|
dispatcher: proxyAgent,
|
|
protocols: ['echo', 'chat']
|
|
})
|
|
```
|
|
|
|
If you do not need a custom Dispatcher, it's recommended to use the following pattern:
|
|
|
|
```mjs
|
|
import { WebSocket } from 'undici'
|
|
|
|
const ws = new WebSocket('wss://echo.websocket.events', ['echo', 'chat'])
|
|
```
