Express 4 handlebars render without layout
Assuming you are using express-handlebars you can specify a different layout from your route/controller when you call the render method. To get rid of the layout altogether you can set the layout to false.
router.get('/', function(req, res) { res.render('home', {layout: false});});
It should be clear, when you have data to render, that the layout should be merely an extra property of such data
var data = { layout: false, var1: var1, var2: var2};res.render('home', data);
If you don't wish to give layout, you have to specify as layout: false . Otherwise app will crash. You can configure as follow, if you need.
app.get('/', (req, res, next) => { res.render('shop', { title: 'My Shop', layout: false })});
