            await client.subscribe("/chat/demo")
            await client.subscribe("/members/demo")

            # send initial message
            await client.publish("/chat/demo", {
                "user": nickname,
                "membership": "join",
                "chat": nickname + " has joined"
            })
            # add the user to the chat room's members
            await client.publish("/service/members", {
                "user": nickname,
                "room": "/chat/demo"
            })

            # listen for incoming messages
            async for message in client:
                if message["channel"] == "/chat/demo":
                    data = message["data"]
                    print(f"{data['user']}: {data['chat']}")

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(chat())
