node.js controllers

server.js

var http = require('http');
var express = require("express");
var app = express();
var controllers = require("./controllers");

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

//map the routes
controllers.init(app);

app.get("/api/users", function (req, res) {
    res.set("Content-Type", "application/json");
    res.send({ name: "Greg", isValid: true, group: "Admin" });
});

var port = process.env.port || 3000;
var server = http.createServer(app);
server.listen(port);

Add controllers folder, add index.js, add homeControllers.js

controllers/index.js, it depends on home controller
(function (controllers) {
     var homeController = require("./homeController.js");
      controllers.init = function (app) {
     homeController.init(app);
    };
})(module.exports);

controllers/homeController.js

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