Dynamically load a new locale on runtime?

[alkstal]

I know this is probably a bad idea considering how typesafe-i18n works, but I've been asked if it's possible and I would like to provide a good answer to it 😄

Would it be possible to get a Translation from an API and load it on runtime without saving anything to disk?

Given I have the Translation object fetched and ready from an API, could I make it work on runtime?

I've seen that loadLocale only really works with the files that exist on disk and that the importer saves and runs the generator.
Everything generated only knows about what's on disk.

But would it be possible in some ugly, hacky way to add a translation and have everything work though?
Or is it not possible to do in a working way?

My own explorations say that no, this is not possible to do, but I might have missed something and in reality it could be easier than I thought. 😄

By default typesafe-i18n generates a lot of boilerplate code for you. This works fine for 95% of projects I guess. If you want to customize the behavior, just set the generateOnlyTypes-option to true and modify the files like you need them.

If you just want to load locales in a different way you can also manually set the loadedLocales object inside i18n/i18n-util.ts.

If you really want to opt opt of the typesafety features, you can load Translations via a ´fetch` calls in runtime, but you will not know if the translated strings contain an error.

I know of some companies that use a combined approach. They save translations to the Git repo once per day to check if translations contain an error, but also load the translations on runtime once per hour to get the latest strings. Maybe this is a solution you want to apply to your project too.
