Node.js, Nodemailer + Express Handlebars, Express + TypeScript.

Nodemailer-express-handlebars is a useful plugin for Nodemailer that allows you to use Handlebars templates in your HTML emails | Link
The documentation on that page does not provide a full usage example and is really short on details. I then found this article which was incredibly helpful! | Link

...
var hbs = require('nodemailer-express-handlebars');
var options = {
viewEngine : {
    extname: '.hbs', // handlebars extension
    layoutsDir: 'views/email/', // location of handlebars templates
    defaultLayout: 'template', // name of main template
    partialsDir: 'views/email/', // location of your subtemplates aka. header, footer etc
},
viewPath: 'views/email',
extName: '.hbs'
};
...
mailer.use('compile', hbs(options));
mailer.sendMail({
from: 'test@test.com',
to: req.body.to,
subject: req.body.subject,
template: 'template',
context: {
    firstName: req.body.firstName,
    lastName: req.body.lastName,
    ...
}
}, function(error, response)...)

Most of my day was then spent trying to figure out how best to put Node.js, Express and its dependencies into a working app via Webpack. I have not been very successful so far... My main issue at present is that when I run Webpack I get a lot of errors that say things like: Module not found: Error: Can't resolve './decode/' etc
I did however, find two articles which look promising and that I will be picking for clues:
TypeScript, Express and Node.js | Link
This is a great article, however, he uses Grunt to build his TypeScript which is not quite what I am looking for.
TypeScript, ExpressJS API with Webpack | Link
Another great article that look to cover most of what I am looking for.
