Here some thoughts on this topic, strictly connected to the chat example provided by Rocket.

Rocket chat example makes use of async streams, in detail it uses EventStream.

The endpoint associated to this stream is then consumed by the client using the js EventSource interface.

This is a good starting point to work on. However, to make the application scalable, we cannot rely on the fact that the service we are querying knows anything about the current room and the state of the match. Thus, we should think about how to manage the retrieval of those informations.

Regarding managed state in Rocket here is a good issue involving Arc and Mutex:
