The target entry-poi

Answer 1

In the project that imports your library, add the following to the tsconfig.json. This ensures that tsc is able to resolve the "missing dependencies" between submodules in your library.

 "compilerOptions": {
    "paths": {
      "mycomponents/*": [
        "./node_modules/mycomponents/*"
      ],

With this, there was no need for whitelistedNonPeerDependencies.
