Websocket vals

[stevekrouse]

Would be cool! Lots of folks ask for it

export default async function(req: Request) {
  const upgrade = req.headers.get("upgrade") || "";
  if (upgrade.toLowerCase() != "websocket") {
    return new Response("request isn't trying to upgrade to websocket.");
  }
  const { socket, response } = Deno.upgradeWebSocket(req);
  socket.onopen = () => console.log("socket opened");
  socket.onmessage = (e) => {
    console.log("socket message:", e.data);
    socket.send(new Date().toString());
  };
  socket.onerror = (e) => console.log("socket errored:", e.message);
  socket.onclose = () => console.log("socket closed");
  return response;
}

As an dependent addon I propose Broadcast Channel for intra-val* communication channel.

(* same val only or same val.town user only, that is vals running in that val.town users context)

now that OpenAI's pushing their realtime framework w/ websockets, and needing a proxy/relay (e.g. https://github.com/m1guelpf/openai-realtime-proxy) — this space will get heated!

Yeah this seems suddenly very very useful. Is this hard to implement, I would not know where to start, I guess a Deno websocket server type of val?
