Node.js module for managing users who are online?

Are there any node.js module for managing users who are online?

By this I mean for a real-time application knowing who is available/connected. Sending messages between them, subscribing to events from different people, etc.

Thanks for any help.

Integration of socket.io for real-time updates in Node.js is what you are searching for.

Sample Code: 

io.on('connection',function(socket){  
    socket.on('update_list',function(data){
      //data.purpose;


      if((String(data.purpose.trim()))=='login'){
        var query="update user set online = ? where id = ?";
        con.query(String(query),['Y',data.id],function(err,rows){
         // var query="select * from user where id !='"+data.id+"'";
          var query="select * from user";
          con.query(String(query),function(err,rows){
            io.emit('logout update',JSON.stringify(rows));
          });
        });
      }else{
        var query="update user set online = ? where id = ?";
        con.query(String(query),['N',data.id],function(err,rows){
          //var query="select * from user where id !='"+data.id+"'";
          var query="select * from user";
          con.query(String(query),function(err,rows){
            io.emit('logout update',JSON.stringify(rows));
          });
        });
      }
    });
});

Sounds like something you could easily do on top of socket.io.
