app.use(bodyParser.json({ limit: '5mb' }));

app.set('views', 'views'); // Set the folder-name from where you serve the html page. app.use(express.static('./public')); // setting the folder name (public) where all the static files like css, js, images etc are made available

app.set('view engine', 'html'); app.engine('html', consolidate.handlebars); // Use handlebars to parse templates when we do res.render

// connect to Database const db = 'mongodb://localhost:27017/uberForX'; mongoose.connect(db).then(value => { // Successful connection console.log(value.models); }).catch(error => { // Error in connection console.log(error); });
