TypeScript - Translation keys

[Liwoj]

Hello

So far I have a great fun using new v9.2.x release - specifically the TypeScript improvements

I have a question (or suggestion)

I was trying to define a TS type, that would be a replacement for a string type for my app internal API's that receive a translation key and sometimes later they call a Vue-i18n function (such as t) on it. Just to enjoy better intellisense and type safety

So far I got this:

import type { PickupPaths } from 'vue-i18n'

// Messages is a type of all my i18n json
export type MessageKey = PickupPaths<Messages>

This works pretty well. Probably only quirk is it accepts "partial path" - like a have a "validation" key with many subkeys one level down and it accepts "validation" (which is an object and not a translation key).

Is there better way ? It would be great if something like that would be "official TS API" and documented..

Thanks!
