The problem with Webpack is that if you want to do something that's not straightforward[1] or covered in the dozen tutorials that are on the web, you're going to have a hard time.

The docs are very basic and there are so many configuration params.

If you want to do something that's not covered in tutorials or boilerplates, be prepared to spend a ridiculous amount of time reading Webpack PRs, issues and the codebase.

Webpack does a great job and it's a nice concept but it has very bad documentation.
