You can use objects that has socket ID as the key and contains the related data.

var socketio = require("socket.io");
var io = socketio.listen(app);
var socketInfo = {};
io.on("connection",function(socket){
    socketInfo[socket.id]  = [];
    socketInfo[socket.id].socket =  socket;
    socketInfo[socket.id].data =  {}; //store socket related data here

    socket.on('disconnect', function() {
        delete socketInfo[socket.id]
    });
}):

For emitting you could do this:

var socket = socketInfo[socketID].socket;
socket.emit('message', socketInfo[socketID].data);
