Sockets io - managing multiple rooms?

Question

Sockets io - managing multiple rooms?

Having trouble managing multiple rooms with node.js and socket.io

socket.on('join_room', function (data) {
   socket.join(data);
});

 socket.on('send_msg', function (data) {
   io.sockets.in(theroom).emit('message', data);
});

If I set the room in a variable (i.e theroom) then naturally that gets over written with the latest room, how can I have multiple rooms?

node.js
sockets
websocket
socket.io

I solved this by writing a function that sends to rooms:

listen: (server, callback) =>
  @server = server
  @logger.debug 'SDL: starting up socket'
  # @socketTool is object returned by socket io require 
  @listener = @socketTool.listen(server, log: true, 'log level': @logLevel )

emitToRoom: (room, type, data, callback) =>
  @logger.debug "all rooms: #{@utilLib.inspect @listener.sockets.manager.rooms}"
  @listener.sockets.in(room).emit(type, data)
  callback() if callback?

I think the thing that you're missing is that the individual socket doesn't understand other rooms, you need to handle that at the listener level.
