I'd gladly discuss it with you as I'm not an expert in packaging libs! I also inspired myself a lot from your MessageFormatTranspiler. Thanks.

1. Please note I used version 2.3.4 of formatjs/intl as more recent version needs at least typescript 4.7. As soon as you update typescript, we can take the latest formatjs/int 2.7.1 at the time of writing.

2. Caching is not yet functional. But I'd like to shortly discuss it before fixing/implementing. Does it make still sense? What should we cache? The AST (decomposition) of the message in ICU Format? The final translated/transpiled message?

@f-aubert Thanks for the PR!
There is a PR for upgrading the internal to the latest versions, let's continue this after it's merged since we want TS v4.7.
Regarding the cache, I'll review it when I have the time and leave comments. (might take a while so be patient 🙂 )

@shaharkazaz the other PR was merged, do we want to go on with this one?

hello @f-aubert @shaharkazaz do we have any update on this? I also cannot ship with unsafe-eval and I use MessageFormat.
