Take on LoopBack 4 if anyone has used it

So i now use Adonis 4.1 as server API and i’m not sure when but they will release v.5 completely rewritten in TypeScript so there will be an bit of a learning curve going from v4.1 to v.5.

I don’t mind the learning curve but LoopBack caught my interest and are already production ready with TypeScript in latest v.4 so i might consider putting my learning curve hours on LoopBack since i really like what i have read about it so far.

So my question is if any one here has any experience using LoopBack 4 as an REST API?
