Basic realtime support (code included):

[earonesty]

I use this for realtime support. It's not great, but it's fine for me.

• one channel
• uses threads
• can be keyboard-interrupted (even on windows)
• 5 second queue poll for interrupts

usage:

   mon = self.conn.monitor("work")
   
   for payload in mon:
       if payload.get("type") == "INSERT":
           log.error("hey, this table shouldn't have inserts")
           mon.send(False)
           break 

the class:

class AugmentedClient(Client):
    def monitor(self, tab):
        wss = self.realtime_url
        key = self.supabase_key

        wsv1 = f"{wss}/websocket?apikey={key}&vsn=1.0.0"

        q = queue.Queue()

        data = None
        def do_callback(payload):
            nonlocal data
            data = payload
            q.put(payload)

        s = Socket(wsv1, auto_reconnect=True)

        def thread_run():
            loop = asyncio.new_event_loop()
            asyncio.set_event_loop(loop)
            s.connect()
            channel = s.set_channel(f"realtime:{self.schema}:{tab}")
            channel.join().on("*", do_callback)
            s.listen()

        thread = threading.Thread(target=thread_run, daemon=True)
        thread.start()

        prev_sig = signal.getsignal(signal.SIGINT)
        def signal_handler(signal, frame):
            q.put(None)
            if prev_sig is not None:
                prev_sig(signal, frame)
        signal.signal(signal.SIGINT, signal_handler)

        while True:
            try:
                ret = q.get(timeout=5)
            except queue.Empty:
                continue

            if ret is None:
                s.ws_connection.close()
                break

            # user can .send(False) to interrupt loop and close the channel
            ok = yield ret
            if ok is False:
                q.put(None)
                yield None

Any possibility this could be used with JWT's instead of the service_role API key? (Or even just a regular access_key after signing in a user with email & password?)

Realtime support has landed in 2.7.2 and is available in the async client.
