My file structure:

@sebastian3495 this is not an npm issue. is for the npm CLI, its registry, and such products and tools, not for support with individual libraries hosted on the registry.

Please forward this to the webpack-node-externals issue tracker.

I forgot to add, that even without the use of webpack-node-externals, I still somehow is unable to exclude node_modules. I assume this also regards npm now?

npm doesn’t define webpack’s own behavior. If it’s a webpack bug, you have to then go to webpack’s issue tracker, and so on.

Will do then. You may delete this thread.
