Question

I want to use
req.user.id
inside
io.sockets.on('connection', module.exports = function(socket){}
so I tried to using this line
socket.request.client.user
like that on my
io.socket
io.sockets.on('connection', module.exports = function(socket,client,req){
connections.push(socket);
app.use(session({ secret: 'keyboard cat',resave: true, saveUninitialized:true})); // session secret
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
console.log('connected: %s socket connected -session',socket.request.client.user ,connections.length);
but i get undefined on console

req.user is only available in express middleware unfortunately. You'll have to use something like https://www.npmjs.com/package/passport.socketio if you want to access passports user info.
You will have to use some sort of persistent store as well such as redis or mongodb
