Mark files to be code split #21
Description
Right now, I can use externalize magic comment to provide a human-readable module name. However, marking a file to for a human-readable module name does not split that marked file out into a chunk.
Current Scenario
Website A
In order to ensure that website A provides me with an independent chunk, I do the following import(/* webpackChunkName: "hello-world"*/ './components/hello-world')
This leverages standard Webpack functionality and ensures that I end up with a hello-world.js file, which can be consumed independently inside Website B.
The goal
I don't want to be forced to code split a file using import(), if a file is marked to be externalized, then webpack should automatically chunk that file out on its own.
After some research, I have found a plugin which allows for modifying how the assets are chunked out and grouped together. A good starting place would be to look at how this is done in this plugin and extract the main mechanism used.
