I am working on a PR that would support merging multiple translation files when translating an application. So if a library author provided a set of translation files it would be possible to combine them with the application translations.

This would then need to be integrated into the Angular CLI.

Further, we should look into how best to make this seamless. For instance agreeing on a file naming convention (or perhaps a property in package.json) that told the CLI where to look for such files.

I also have a PR in the works for doing $localize based i18n message extraction from distributable files. We need to ensure that we can avoid extracting messages that came from libraries and were bundled into the main.js for example.

Can we use merging multiple translation files in angular 10?
I am currently using loadTranslations to solve the problem of multiple translation files.

By the way, is the dynamic switching of languages not supported by ivy？
