NodeJS URL Routing and Render HTML

Question

Im new at nodejs programming and im having a little problem now. When i try to go localhost:3000/ i want to go homeController and index function prints the HTML file.

APP.JS

const express = require('express')
const mongoose = require('mongoose')
const mongodb = require('mongodb')

const app = express();

const homeController = require('./home/homeController.js');


app.get('/', function(req, res) {
    res.redirect(homeController.index);
});

app.listen(3000, () => console.log('Example app listening on port 80!'))

HOMECONTROLLER.JS

var path    = require("path");

exports.index = function(req, res){
  res.sendFile(path.join(__dirname+'/index.html'));
};

console.log('test33');

Also i am using exports to seperate app.js from other controllers. Is this the right way? I have a history with Python Django framework and we used to use URLs to navigate our program.

Thanks.

Your problem is that homeController.index is a function, but you're not calling it. Replace:

app.get('/', function(req, res) {
    res.redirect(homeController.index);
});

with:

app.get('/', homeController.index);

Your homeController.js exports an index function which requires two parameters reqand res. So you have to update your app.js accordingly :

app.get('/', function(req, res) {
  homeController.index(req, res);
});

edit: by the way, your app is listening to port 3000
