How to access session in socket(Node.js)

Question

I am using express and socket.io for developing a random chat application.Now i need to access session in socket event.

io.sockets.on('connection', function(socket){  
  socket.on('sendMessage',function(data){
   session.userId //senderId
 }); 
});

session is available in request object but is there is easy way to access session in socket events.I have checked these questions but the answers are quite complicated and old.

Answer 1

I found a simple way for this..
If you're using socket.io >= 1.0 here is a simple module

var ios = require('socket.io-express-session');
var io = require("socket.io")(server);
io.use(ios(Session));

then

var sess = socket.handshake.session;
sess.userId

As simple as that.

reference session.socket.io
