Pass existing WebSockets into realtime APIs

[I've been experimenting with Supabase running on Cloudflare Workers]( - basic API requests are working, but I'm stuck on working with realtime data! We recently [announced WebSocket support]( in Workers. You can work with WSs in Workers by creating a WebSocketPair, which is an object containing a _server_ and _client_ WebSocket. The client WebSocket is sent down to the client, and the server WebSocket remains available in an open connection for the Workers function to work with: This server WebSocket instance is a great candidate for being used by Supabase to provide realtime data _through_ the Workers function to the client. Our [WebSocket API]( is fairly similar to the w3c spec, but differs in some respects, specifically around event handling (we use addEventListener instead of onopen, onclose, etc.) and a few fields we don't implement. It would be great to use these WebSockets with Supabase! Given that we already create WebSockets in Workers via our own…
