Module resolve error when using node packages edge case

[josias-r]

I'm working on a project, where I've split some logic into a separate package. As it is conventional, inside that separate project I export all components and utilities through the main entry file, so I can have clean imports on my nextjs project again.

Now I have some utils inside my splitted package, which use the node package "fs" for instance. This will cause a build error, even though I never import the said util into client-side components or pages from my project.

My util is only used inside the getStaticProps and Paths methods, which is okay since node packages are available inside those.

The current workaround I'm using was to move the utils which rely on node packages into a separate file, so webpack will never go there form the nextjs project.

This forces me to have some rather "ugly" imports through a build folder, since I'm working with typescript.

It would be nice if nextjs would not detect methods which work with node packages, unless they are getting imported.
