Angular MonoRepo Secondary Enpoints with different paths

Question

I have a monorep using @nx and @angular and I have setup a folder structure as follows:

libs
- ui-components
--_components
---atoms
----alert
---molecules
----datepicker
--alert
--datepicker

As you can see, all folders and files reside in the ui-components folder. In my tsconfig.base.json I have setup secondary endpoints for the library root components as follows:

"@library-name/ui-components/alert": ["libs/ui-components/alert/index.ts"],
"@library-name/ui-components/datepicker": ["libs/ui-components/datepicker/index.ts"],

and in those root folders I just have an index.ts and a ng-package.json. The index.ts is pointing to the _components folder at the respective component like this:

export * from '../_components/atoms/alert';

If I run my project or storybook, it works fine. But if I try to build the project, I get this error:

/_components/atoms/alert/index.ts' is not under 'rootDir' '

I have tried many ways to solve this. One way was to add a ng-package.json to the actual component (in /_components/atoms/alert/) and then change the <rootDir>/alert/index.ts to this:

export * from '@library-name/ui-components/_components/atoms/alert';

While this does work, it causes the built library to have 2 endpoints, 1 in root and 1 in the _components directory. This might not seem like an issue, but GitLab has a character count limit for package.json and having duplicates puts us over that limit.

So, I need to solve this without using secondary entries. Anyone have any ideas?

If you build that project, you will see this in package.json (for the ui-components library)

    }
  }
}

Note the double endpoints for each component. I don't want the "internal" endpoints (any that have the _components directly in them)
