TypeError: Cannot read property 'get' of undefined (Node.js)

I am new in Node.js and I need help. I am trying to develop a simple program using express (^4.14.1), path (^0.12.7) and vash (^0.12.2) modules in Visual Studio. I have just created a couple of files that I show you below. homeController.js and index.js files are inside the controllers folder.

package.json

{
"name": "the-board5",
"version": "0.0.0",
"description": "TheBoard5",
"main": "server.js",
"author": {
"name": "Utku"
},
"dependencies": {
"express": "^4.14.1",
"path": "^0.12.7",
"vash": "^0.12.2"
}
}


server.js

var http = require("http");
var express = require("express");
var app = express();
var controllers = require("./controllers");
var port = process.env.port || 1337;

app.set("view engine", "vash");

controllers.init();

http.createServer(app).listen(port);


homeController.js

(function (homeController) {
homeController.init = function (app) {
app.get("/", function (req, res) {
res.render("index", { title: "Express + Vash" });
});
};
})(module.exports);


index.js

(function (controllers) {
var homeController = require("./homeController");
controllers.init = function (app) {
homeController.init(app);
};
})(module.exports);


The problem is that I am getting this error.

C:\Users\Utku\documents\visual studio 2015\Projects\TheBoard5\TheBoard5\controll
ers\homeController.js:5
app.get("/", function (req, res) {

You missed passing app in line

controllers.init();

It should be

controllers.init(app);
