Autocomplete for compiled project

[Ianneee]

I have my own library with compiled modules to use in my projects, which also involve my collaborators. The issue is that since it's compiled, I can't get autocomplete for custom HTML tags, making the work a bit challenging. I was thinking I could use VS Code custom data to integrate tags from my library, but doing it manually is impractical.

I'm wondering if the Angular Language Service can output analysis of the code before it's compiled, so it can be converted into JSON for custom data, or if there's already a system in place to get autocomplete in my scenario.
