Multiple chat rooms?

[sergiuszkierat]

@eduardofcbg, I could imagine that the multiple rooms is a next step for this activator. There are many aspects how to do it. To simplify, we can assume that we can create some static rooms so as to choose one of them on the first screen. After selecting a room, you should subscribe to an appropriate room's topic. A ChatRoom actor is only to manage a cluster communication.

We invite you to create PR in order to cooperate with code.

@sergiuszkierat Thanks for the quick reply and I will take your invitation.
It seems easy enough to implement what you suggest. The UserSocket will take a specific room's id, which the actor will subscribe to.
A problem arises if I want to save state in a specific room. For that wouldn't I need a different actor for each one? In that case I'm having trouble getting my head around where to instantiate that actor. I guess I could create several in the controller, but what if I want to create them on demand when some user connects to a certain url?
Thanks a lot for you time.

@eduardofcbg Not really, there should be only one UserSocket which is used to communicate between a user's browser and a web server. Instead of this, you should extend a ChatMessage. There should be changed a chat.coffee as well.

To have a state of your chat, you should use a persistance layer, so far a chat is volatile in his behaviour. If you switch between rooms, you should retrieve a data from server.

I was thinking of using akka's event sourcing. Your suggestion simplifies a lot the problem, but in that case the actors will not have any actual state. I will rethink the solution.
Thanks a lot.
