Sockjsio is an extention on the great, great sockjs-node server. Providing multiroom functionality.

Warning: Version 0.0.1 is in the absolute alpha fase and created by a Node beginner. I must be doing some things wrong, please feel free to correct me with feedback.

Sockjsio is a multiroom manager based on the sockjs client ( and sockjs-node ( server.

Dependecies are aync and sockjs. Install if not allready done

npm install sockjs
npm install async

Defining a server is plane and simple:

var sockjsio = require('./sockjsio');

sockjsio.listen( port[int], url[string], prefix[string], sendRoomNames[bool] );

If 'SendRoomNames' is true, every response to a room hase a property roomName, corresponding that roomname. Just pick a prefix like '/A', channels are not used since we use rooms.

A simple echo example:

var sockjsio = require('./sockjsio');
sockjsio.listen( 8080 , '', "/A", true );

sockjsio.on('connection', function( connection )
connection.on('roomopen', function( roomName )
    console.log( + " opened room " + roomName );


    connection.on('data', function( response )
            var data = JSON.parse( response );
            // possible ways to send a message
            connection.emitRoom( data.roomName, data.message );         // Send to whole room including connection
            connection.broadcastRoom( data.roomName, data.message );    // Send to all in this room but connection
            connection.sendRoom( data.roomName, data.message );         // Send to this connection if in this room

            connection.emitClient( data.message );                      // Send to all clients on the server
            connection.broadcastClient( data.message );                 // Send to all except connection
            connection.sendClient( data.message );                      // Send to this connection

    var isInroom = connection.isInRoom('room1');                    // = true if in 'room1' 
    var joined = connection.joined();                               // Array with roomnames

Within the connections there are some handy events they all return the roomName.

connection.on('roomopen', function( roomName )
    console.log( + " opened room " + roomName );
  • roomopen: fired when room hase opened.
  • roomclose : fired after a room hase closed.
  • leaving: fired when a client left a room.
  • joining: fired when a client hase joined a room.

There are two other functions within connections:

var isInroom = connection.isInRoom('room1');            // Bool true / false    
var joined = connection.joined();                       // Array with roomnames the client joined

To make it complete:

var roomExists = sockjsio.roomExists("room2");          // False: this user hase left the room
var usersInRoom = sockjsio.usersInRoom("room1");        // Array with connection id's of joined sockets
var clients = sockjsio.clients();                       // Array with all connection id's on the server
var client = sockjsio.client(socketID);                 // Get a socket with that ID
