i'm not sure
Description
when i export a component in the library module but not in the public API
the build command throw errors only in normal mode, but in production mode it completes successfully
🔬 Minimal Reproduction
clone https://github.com/robertIsaac/test-library
and run ng b and ng b --prod
or generate from scratch
ng new test-library --create-application=false
cd test-library
ng generate library test-library
ng g c test-export --export
ng b
ng b --prod
🔥 Exception or Error
both commands should throw the following error
Unsupported private class TestExportComponent. This class is visible to consumers via TestLibraryModule -> TestExportComponent, but is not exported from the top-level library entrypoint.

Anything else relevant?
it would be nice if --export command also update the public api file if it's running inside a library Reacted by Daniel Kimmich, Hadrien TOMA, nhhockeyplayer and Andrew Cunliffe Activitychanged the title [-]Unsupported private class doesn't throw on building library for production[/-] [+]Unsupported private class error doesn't throw on building library for production[/+] on Apr 21, 2020alan-agius4 commented on Apr 21, 2020 @robertIsaac, the problem here is that the above is only an error when using Ivy rendering engine, with View Engine which is used for production builds, this is valid.
That said, we should add the export to the public api when using the schematics so that we generate valid code for both rendering engines. Reacted by robertIsaac, Samarasimhareddy Kommireddy, Daniel Kimmich and nhhockeyplayer SvenBudak commented on Feb 4, 2022 Any news?`i sitll have this issue on a new generated project with angular version 13.1.0 Reacted by Maxime Lyakhov alan-agius4 commented on Jul 4, 2022 SvenBudak commented on Jul 4, 2022 alan-agius4 commented on Jul 4, 2022 Amit221060 commented on Oct 6, 2023 Do we need to add all exports in public.api.ts or any other work around after angular 12.
