express passport check if user is authenticated - node.js

Question

I am using passport to login and display '/home'.The login works and redirects to '/home'.But this end point is not protected and can be accessed by typing in the browser.I tried using req.isAuthenticated() (and went through multiple questions here) to no avail.
Routes//index.js
var express = require('express');
var router = express.Router();
var User = require('../models/user');
var passport = require('passport');
var session = require('express-session');
const LocalStrategy = require('passport-local').Strategy;
passport.use(new LocalStrategy(
function(username, password, done) {
User.findOne({
username: username
}, function(err, user) {
if (err) {
return done(err);
}
if (!user) {
return done(null, false);
}
if (user.password != password) {
return done(null, false);
}
return done(null, user);
});
}
));
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
router.get('/login', function(req, res, next) {
res.render('login');
});
router.post('/login', passport.authenticate('local', { failureRedirect : '/', successRedirect : '/home'}))
router.get('/register', function(req, res, next) {
res.render('register');
});
router.get('/logout', function(req, res){
req.logout();
res.redirect('/');
});
router.get('/home', ensureLocalAuthenticated, function(req, res){
res.render('home', { user: req.user });
});
function ensureLocalAuthenticated(req, res, next) {
console.log(req.isAuthenticated());
if (req.isAuthenticated()) { return next(); }
res.redirect('/login');
}
module.exports = router;
on my app.js file i have configued passport like this:
//passportconfig
app.use(passport.initialize());
app.use(passport.session());
passport.serializeUser(function(user, done){
done(null, user.id)
})
passport.deserializeUser(function(id, done){
User.findById(id, function(err, user){
done(err, user)
})
})
app.use('/', indexRouter);
app.use('/users', usersRouter);
isAuthenticated is always returning false,cant login with that middleware.If i remove it,i can login fine but then the '/home' is accessible by all users

Adding the following lines to app.js worked for me:
app.use(require('express-session')({
secret: 'keyboard cat',
resave: false,
saveUninitialized: false
}));
So passport is configured as follows:
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var passport = require('passport');
var mongoose = require('mongoose');
var User = require('./models/user')
const LocalStrategy = require('passport-local').Strategy;
Using them:
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('express-session')({
secret: 'keyboard cat',
resave: false,
saveUninitialized: false
}));
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(express.static(path.join(__dirname, 'public')));
//passportconfig
app.use(passport.initialize());
app.use(passport.session());
// used to serialize the user for the session
passport.serializeUser(function(user, done) {
done(null, user.id);
//
});
// used to deserialize the user
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
