Recommended migration strategies?

electron-webpack does an amazingly good job of hiding the complexity behind putting together a complex Electron app.

Since the project is unmaintained, folks have started sharing alternate boilerplates, tools and stacks they're using to replace it, but what I haven't been able to find is a tool or walkthrough for surfacing the full configurations that electron-webpack currently uses on a given project. With its variety of extension mechanisms and computed configuration files, it's not been all that straightforward for me to figure out what the "vanilla" config files for an existing project would be for webpack, babel, and friends.

Does anyone have recommendations or advice on that front?
