I'd be happy to learn more about this approach. I'm very trailing-edge in most of the technologies I use, because I regularly switch between dev to admin to helpdesk, so a link that goes into how this works and why would be appreciated.
If you are just starting out with this, I would recommend looking into Parcel (Getting Started). It's an easy to configure bundler. You can get up and running in a few minutes.
I personally prefer Webpack (Getting started) because I am more familiar with it. You'll have to be familiar with other toolsets, like babel or webpack-devserver, etc. It's more work.
Got questions, hit me up on Twitter!
