Is there a way to get a list of available rooms live?

Is there a way to get the list of available rooms live without calling getAvailableRooms at some interval?

I did not find anything in the documentation(

My other thoughts were to get a socket instance from Colyseus and send a socket message when the room is created and deleted

Example:

 onCreate(){
 ...
  ws.send('available-rooms', <ArrayOfAvailableRooms>);
...
 }

But I get such error Error: seat reservation expired. when I try to connect to the socket using general methods instead of Colyseus.

So the next question is, can I just connect to the socket without using Colyseus client?

I have one more crazy idea. XD. I can create a separate room that will be responsible for the available rooms. This room has a state with available rooms. Other rooms change the state of this specific room. And client has a sync callback when rooms change
Do you think this is a very bad idea?)

HI @bedryck, that is essentially what the LobbyRoom does :) though, it doesn't use the state - it only sends data as the rooms become available or unavailable. You can take a look at the sources here: https://github.com/colyseus/colyseus/blob/master/packages/core/src/rooms/LobbyRoom.ts

The LobbyRoom uses the (yet undocumented) subscribeLobby method, which is a "global" subscription for when rooms are available/unavailable.

Oh, thanks!
