Please help me!

In fact the problem was in my implementation of express-load, it injects dependencies but does not configure the app, so I decided not to use it:

app.js

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

var routes = require('./routes/home'),
    contacts = require('./routes/contacts');


var app = express();

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');


app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(session({
    secret: 'secret',
    resave: true, 
    saveUninitialized: true
}));
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/contatos', contacts);

app.listen(3000,function(){
    console.log('Started!');
});

routes/home.js

var router = require('express').Router();
var home = require('../controllers/home');

router.get('/', home.index);
router.post('/entrar', home.login);
router.get('/sair', home.logout);
module.exports = router;

controllers/home.js

module.exports = {
    index: function(req, res) {
        /*do somethings*/
    },
    login: function(req, res){
        /*do somethings*/
    },
    logout: function(req, res){
        /*do somethings*/
    }
};

There must be a better way to implement using express-load with express4, but not yet found.
