sorry, I decided to use hbs instead after that. but basically I just followed the basic guide from here

app.engine('hbs', handlebars({
layoutsDir: __dirname + '/views/layouts',
extname: 'hbs',
//new configuration parameter
defaultLayout: 'planB',
}));
app.get('/', (req, res) => {
//instead of res.render('main', {layout: 'index'});
res.render('main');
});
