Using express-handlebars, you should use the advanced mode and create an instance of it like in this example.

The proper way would be to create a view file (like you probably already have per you question) and use the express handlebars instance to render it:

// init code
var exphbs = require('express-handlebars');
var hbs = exphbs.create({
    defaultLayout: 'your-layout-name',
    helpers: require("path-to-your-helpers-if-any"),
});
app.engine('.file-extention-you-use', hbs.engine);
app.set('view engine', '.file-extention-you-use');

// ...then, in the router
hbs.render('full-path-to-view',conext, options).then(function(hbsTemplate){
     // hbsTemplate contains the rendered html, do something with it...
});
