I’m calling some clojure from kotlin, would it be idiomatic to put it all in a spring component, and use that fro the interactions? This way I have the non-type-safe stuff all in one place, other code can use the ‘typesafe’ functions from the component?

no experience but that would be interesting perhaps when it works, you would be able to write a blog post about it?

I probably could, but for now I just try to build a little thing in Kotlin from clojure, also using avro and postgress, with some data types like UUID. It’s for an internal workshop about event sourcing.

have fun!
