Issue with using source files as types

[jakub-msqt]

Summary

In the docs, it's recommended to use source files as types. However, if the consuming application tsconfig moduleResolution setting differs from the one in the package, the build or typecheck tasks on the consuming application fail because it's also checking the package's source files through node_modules even though those are excluded in tsconfig of the consuming application.

E.g. app with moduleResolution: "bundler" and package with moduleResolution: "nodenext" disagree on where @ts-expect-error needs to be used or not.

It would be solved if the app's task didn't typecheck the package's types. Didn't find a way to do it in this setup. Any ideas?
