JavaScript for PHP Geeks: Webpack for Module Loading Awesomeness

What you’ll be learning

In JavaScript, if you’re still manually including each JavaScript file you depend on with a script tag… there’s a better way! ES6 introduced the concept of modules: the ability (finally!) to isolate our JavaScript into small components that live in different files (like we do with classes in JavaScript).

But, to get this to work on the web, we need some help. We need something that’s able to read our imports and aggregate everything we need into a single JavaScript file. We need webpack:

Using npm… and then yarn for package management

Webpack setup: package all modules into a single file

Calling Babel from webpack via a loader

Webpack dev tools for fast development

Webpack Hot Reloading!?

Handling multiple files (“entry points”)

Using Uglify and prepping for production

Cache-busting with hashed filenames

CommonsChunkPlugin: package common modules together

Loading & Packaging CSS/SCSS & images form JavaScript!?

And most importantly: become empowered to (finally) write organized JavaScript!
