Function connect

connect(url: string, opts?: WsConnectOptions): Promise<WsConnection>
Opens a WebSocket connection from a Cloudflare Worker.

Performs the outbound client handshake with a fetch upgrade (the runtime handles the wss TLS, RFC 6455 framing, and client masking), accepts the returned socket, then yields a WsConnection you async-iterate for inbound messages. Offered subprotocols are sent as a comma-joined Sec-WebSocket-Protocol header; any opts.headers are merged in.
Parameters
- url: string
  The ws:// or wss:// endpoint to dial.
- opts: WsConnectOptions = {}
  Optional subprotocols and extra request headers.
Returns Promise<WsConnection>
The connected WsConnection.
Throws
If the server does not complete the upgrade or fetch fails.

Since
1.0.0
Example
```
import { connect } from 'edgeport/ws';

const ws = await connect('wss://echo.example.com', { protocols: ['chat'] });
ws.send('ping');
for await (const msg of ws) {
	if (msg.type === 'text') console.log('reply:', msg.data);
	break;
}
ws.close(1000, 'done');
const { code } = await ws.closed;
console.log('closed with', code);
```
