Description

If I create a repo made of two libraries for which one depends on the other I can’t figure out how to package the one that depends on the other. I get the error shown below.

How To Reproduce

I have a repo setup here. The libraries are in the packages folder. Note that ng-date-utils depends on ng-utils. But I get this error trying to package ng-date-utils.

Using the programmatic API, we are able to package the libraries in order, and during the packaging we are able to use the already packaged libraries. This packaging process uses a custom tsconfig that looks for the libraries in the place they are packaged to. The order of packaging is very important, as the libs with dependencies must package after the dependecies have finished packaging. Something like:

await ngPackagr()
    .forProject('/usr/local/lib-1/package.json')
    .withTsConfig('tsconfig.packagr.json')
    .build();

await ngPackagr()
    .forProject('/usr/local/lib-2-that-depends-on-lib-1/package.json')
    .withTsConfig('tsconfig.packagr.json')
    .build();

Please check the ngPackagr code for the exact API here: https://github.com/dherges/ng-packagr/blob/v2.4.1/src/lib/ng-v5/packagr.ts

https://www.npmjs.com/package/rollup-plugin-paths

but I am not sure if there is a way to include plugin in ng-packagr , someone knows if is something possible?
