Socket Io Private Room

We will allow users to choose a username and allow them to chat using them.

Socket io private room.

We can retrieve this list and use it as needed. So first let us set up our html file to request for a username var app require. Within each namespace you can also define arbitrary channels that sockets can join and leave. To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.

The list will be dynamically updated if the socket leaves any of its rooms. These channels are called rooms. One thing to keep in mind while using rooms is. Each socket in socket io is identified by a random unguessable unique identifier socket id for your convenience each socket automatically joins a room identified by its own id.

In this recipe we will create a list of the rooms that our socket is in. Now that we are well acquainted with socket io let us write a chat application which we can use to chat on different chat rooms. In that case every socket in the room excluding the sender will get the event. Socket io provides a dynamic list of the rooms that each socket is a member of.
