Node.js module.exports passport isAuthenticated to routes - node.js

Question

I wanted to separate each group of routes in a file. I need to use isAuthenticated in most routes to restrict access. When I put all routes in the same file it works.
When I use module.exports = isAuthenticated in auth.js and in order.js I use var auth = require('auth.js'); I will get a error of 'isAuthenticated is not defined' when I go to http://localhost:3000/order the routes defined in auth.js just works as expected.
I'm using Express.js middleware 'Passport local strategy' (followed tutorial from tutsplus and downloaded github repository from here).
My project structure:
bin/www
models/auth/init.js
models/auth/user.js
models/auth/signup.js
models/auth/login.js
models/order.js
views/error.pug
views/index.pug
views/home.pug
views/layout.pug
views/order.pug
views/register.pug
routes/order.js
routes/auth.js
public/stylesheets/style.css
app.js
db.js
./routes/auth.js:
var express = require('express');
var router = express.Router();
var isAuthenticated = function (req, res, next) {
// if user is authenticated in the session, call the next() to call the next request handler
// Passport adds this method to request object. A middleware is allowed to add properties to
// request and response objects
if (req.isAuthenticated())
return next();
// if the user is not authenticated then redirect him to the login page
res.redirect('/');
}
module.exports = isAuthenticated;
module.exports = function(passport){
/* GET login page. */
router.get('/', function(req, res) {
// Display the Login page with any flash message, if any
res.render('index', { message: req.flash('message') });
});
/* Handle Login POST */
router.post('/login', passport.authenticate('login', {
successRedirect: '/home',
failureRedirect: '/',
failureFlash : true
}));
/* GET Registration Page */
router.get('/signup', function(req, res){
res.render('register',{message: req.flash('message')});
});
/* Handle Registration POST */
router.post('/signup', passport.authenticate('signup', {
successRedirect: '/home',
failureRedirect: '/signup',
failureFlash : true
}));
/* GET Home Page */
router.get('/home', isAuthenticated, function(req, res){
res.render('home', { user: req.user });
});
/* Handle Logout */
router.get('/signout', function(req, res) {
req.logout();
res.redirect('/');
});
return router;
}
./routes/order.js:
var express = require('express');
var router = express.Router();
var order = require('../models/order');
var auth = require('./auth.js');
module.exports = function(passport){
router.get('/order', isAuthenticated, function(req, res){
res.render('order');
});
router.post('/order', isAuthenticated, function(req, res)
{
var testorder = new order({
orderid: '52363',
productname: 'it works',
quantity: 1337
});
testorder.save(function (err) {
if (err) {console.log(err.stack);}
console.log('saving done...');
});
res.render('order', { product: req.body.productname });
});
};

var initPassport = require('./models/auth/init.js');
initPassport(passport);
var auth = require('./routes/auth')(passport);
var order = require('./routes/order');
app.use('/', auth);
app.use('/order', order);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {

});
// development error handler

Try auth.isAuntheticated(),
It should work that way.
