var app=express();
app.listen(3000);

var express=require('express'),
        cookieParser = require('cookie-parser'),
        session=require('express-session');

var app=express();
    var routes=require('../app/routes/index.server.routes');
    routes(app);

    app.use(cookieParser());
        app.use(session({
            saveUninitialized: true,
            resave: true,
            secret: "This is a secret"
        }));

module.exports=function(app){
    var indexController=require('../controllers/index.server.controller');
    app.get('/',indexController.render);

I install the required modules needed. Still it could not create a session. can someone point out the mistake. Updated complete code

This line `router= require('router');` what is this `router` module? From your code it's not very clear how you are attaching your action to a route. — xdc, Nov 11 '15 at 19:35
In astack overflow post it was written that in order to use session we need cookieparse aswell as router modules. so i used that — lch, Nov 11 '15 at 19:37
What `router` module? Express 4 doesn't have any `router` module. You use `express.Router()` instead if you want a `Router` object. Can you add the code on how you are actually attaching your `render` action to your app? — xdc, Nov 11 '15 at 19:56
Forget about that router. even i dont know about that . updated complete code — lch, Nov 11 '15 at 20:00

Register your routes after you register your middlewares:

var app=express();
var routes=require('../app/routes/index.server.routes');

app.use(cookieParser());
app.use(session({
    saveUninitialized: true,
    resave: true,
    secret: "This is a secret"
}));
routes(app);
