angular-cli library create secondary entry point

Question

I am trying to create what I believe is called a secondary entry point into my angular npm package. I want the following two entry points

@scope/data-service
@sc         


        

Answer 1

Example Folder Layout for Secondary Entrypoints

All you have to do is create a package.json file and put it where you want a secondary entry point to be created. One way this can be done is by mimicking the folder structure of the following example which has a testing entry point in addition to its main entry point.

my_package
├── src
|   ├── public_api.ts
|   └── *.ts
├── ng-package.json
├── package.json
└── testing
    ├── src
    |   ├── public_api.ts
    |   └── *.ts
    └── package.json

The contents of my_package/testing/package.json can be as simple as:

{
  "ngPackage": {}
}

No, that is not a typo. No name is required. No version is required. It's all handled for you by ng-packagr! When built, the primary entry point is imported by import {..} from '@my/library' and the secondary entry point with import {..} from '@my/library/testing'
