- typepscript-lib (shared-ts-lib): simple typescript module with a single exported class
target is es2015, module is CommonJS because I need to use that lib in a JS application as well
NOTE: there is a postbuild script that builds the actual lib when referenced
- angular-cli-lib : component lib generated using
ng new angular-cli-lib
ng generate module demo
ng generate component demo/MyComp
Added a reference to shared-ts-lib in it (relative file)
Use that reference in the MyComp component
#BUG #1: Can't find exported class of a CommonJS lib
cd angular-cli-lib
npm i
npm run packagr
leads to
BUILD ERROR
'MyClass' is not exported by ../typescript-lib/dist/shared.tsmodule.js

BUT, if you change the tsconfig.json module to es6 in shared-ts-lib, it builds
#Bug 2: Cannot read property 'flags' of undefined
if you uncomment the export of the shared-ts-lib in src/public_api.ts
leads to
BUILD ERROR
