Repro steps.

Use monorepos pattern for having multiple apps and libs and then extract strings for each app. They all contain references to all strings whether used or not.

Command: https://github.com/intellix/nx-cli/blob/master/package.json#L13

References to strings in other apps: https://github.com/intellix/nx-cli/blob/master/apps/red/src/locale/messages.xlf#L26

References to lazy module that’s not used/referenced by that app: https://github.com/intellix/nx-cli/blob/master/apps/red/src/locale/messages.xlf#L77

Desired functionality.

I’d like extraction (and pretty much everything through ngc) to only be based on context of the app and it’s entrypoints (static or lazy). In the example repository, the Red app doesn’t reference or have a loadChildren reference to LazierModule but still gets strings extracted for it and all the other apps.

We’ve got feature modules defined as libs and a couple of apps that include some of them. The product owners of apps are confused why they’re translating strings for features they don’t have and for other apps

Mention any other details that might be useful.

I think this is a non-issue now that CLI uses a workspace file and can have several distinct applications, each of them with its own tsconfig files. Let me know if that’s not the case.

Nice, fyi you can extend another tsconfig file instead of copy pasting everything in each file. If you only need to change the exclude, it’s easier to have a generic app config file, extend it and just change that
