Most of the F# code from Wlaschin’s book is more or less applicable to ReScript too. We just don’t have computation expressions or the like. Also we tend to prefer simplicity over DRY, because Functors (for instance) are usually not worth the hassle if you accept just a little bit of code duplication.
I just found out that our user @hoichi did a talk about this exact topic Domain Modelling and Architecture for ReScript Apps | Talk at HolyJS 2023 Spring maybe he has some english material available as well?
