Class: WebSocket

⚠️ Warning: the WebSocket API is experimental.

Extends: EventTarget

The WebSocket object provides a way to manage a WebSocket connection to a server, allowing bidirectional communication. The API follows the WebSocket spec and RFC 6455.

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.

Example:

This example will not work in browsers or other platforms that don't allow passing an object.

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:

import { WebSocket } from 'undici'

const ws = new WebSocket('wss://echo.websocket.events', ['echo', 'chat'])
