As part of prepping that, I finally had to sit down and figure out dynamic namespaces in socket.io. There is some really tricky business to namespaces, dynamic or otherwise, particularly when it comes to listening for messages and events server-side sent from connected clients on the namespace. Socket.IO Tutorial With io.js and Express. Socket.IO enables real-time event-based communication. What that means is that we can communicate to the server from the client and in return the server can talk back to the client. Socket.IO uses WebSockets when it can.

Socket io emit to room

Emit cheatsheet, emit() are the main two emit methods we use in Socket. io's Rooms (https://github.com/LearnBoost/socket.io/wiki/Rooms) Rooms allow simple partitioning of the connected clients. This allows events to be emitted with to subsets of the connected client list, and gives a simple method of managing them. You can emit to several rooms at the same time: io.to ('room1').to ('room2').to ('room3').emit ('some event'); In that case, an union is performed: every socket that is at least in one of the rooms will get the event once (even if the socket is in two or more rooms). You can also broadcast to a room from a given socket:
Socket.io rooms difference between broadcast.to and sockets.in , socket.broadcast.to('game').emit('message', 'nice game');. // sending to all clients in 'game' room(channel), include sender. io.in('game').emit('message', 'cool In socket.io, you usually use a specific syntax on the server side if you want to send a message to a specific room: io.to(room).emit('event', 'message');.
