Node.js Question

Using Node.js + Express without template engine

I have tried looking through all of the questions resolved by StackOverflow regarding people receiving this error:

Error: No default engine was specified and no extension was provided.

I feel like I have scoured every post on SO and none of the answers have corrected my code. There must be something else going on.

My issue that I am having is that I already created many html files before making a decision to use Node.js + Express for my rather than worry about converting them all to a templating engine like pug or EJS, I just want to serve them from a static public folder in my directory.

From what I have researched, you do not need a templating engine to use Node.js + Express. But you do need to set up a static public folder to serve your files.

I have included the
app.use(express.static(path.join(__dirname, 'public')));
in my app.js file. I have added a 'public' folder and put all of my static files inside of it, and in my routes file (my index.js file) I have written the following route:

router.get('/', (req, res) => {

I have tried changing it to the following:

  1. res.sendFile('index');

  2. res.sendFile(path.join(__dirname, 'index.html')

  3. res.sendFile('../public/index.html');

I have also tried changing my static middleware syntax to just
and that didn't seem to change anything either.

All of these render the
No default engine was specified and no extension was provided.
error I provided above. I hate that I need to ask this questions when there are so many of the same questions on StackOverflow, but I am currently completely stumped at to what to do. Without further adieu, here is my code:

This is my file directory structure.

Here is my index.js file handling all my routes:

const express = require('express');
const router = express.Router();

router.get('/', (req, res) => {
res.sendFile(path.join(__dirname, 'index.html'));
});'/', (req, res) => {


module.exports = router;

Here's my app.js file:

const express = require('express');
const path = require('path');
const cookieParser = require('cookie-parser');
const bodyParser = require('body-parser');
const routes = require('./routes/index');
const errorHandlers = require('./handlers/errorHandlers');

const app = express();

app.use('/', routes);

app.use(express.static(path.join(__dirname, 'public')));

app.use(bodyParser.urlencoded({ extended: true }));

// If that above routes didnt work, we 404 them and forward to error handler

// One of our error handlers will see if these errors are just validation errors

// Otherwise this was a really bad error we didn't expect! Shoot eh
if (app.get('env') === 'development') {
/* Development Error Handler - Prints stack trace */

// production error handler

module.exports = app;

Here's my package.json:

"name": "********",
"version": "1.0.0",
"devDependencies": {
"grunt": "~0.4.1",
"grunt-contrib-concat": "^1.0.1",
"grunt-contrib-imagemin": "^1.0.1",

"mongod": "^2.0.0",
"mongoose": "^4.13.7",
"nodemon": "^1.14.1",
"normalize.css": "^6.0.0"

Here's my start.js file that runs when I run
npm start

const mongoose = require('mongoose');

// import environmental variables from our variables.env file
require('dotenv').config({ path: 'variables.env' });

mongoose.connect(process.env.DATABASE, { useMongoClient: true });
mongoose.Promise = global.Promise;
mongoose.connection.on('error', (err) => {

const app = require('./app');
app.set('port', process.env.PORT || 7777);
const server = app.listen(app.get('port'), () => {
console.log(`Express running → PORT ${server.address().port}`);
