Functional Event-Driven Architecture

Functional Event-Driven Architecture for the ZIO ecosystem. I hear Zionomicon is evolving again, and that's good news. But there's literally years of more work to do.

https://leanpub.com/feda, This book also by Gabriel vlope is another good one. I bought them together on offer in december. Functional event driven architecture. It done in scala 3

Functional Event-Driven Architecture

Personally, I would go for https://github.com/gvolpe/trading

Gabriel Volpe has a book that goes over just that using the typelevel stack. I highly recommend it: https://leanpub.com/pfp-scala

The only issue I had was how to put all this knowledge together. For that I bought Practical FP in scala by Gabriel Vlope, it's not for beginners, tho but takes you through a project with the latest typelevel stack. Here's the link. https://leanpub.com/pfp-scala.

This is a really good book https://leanpub.com/pfp-scala

If you want a solid understanding of FP and not just FP in Scala, I highly recommend installing GHCup and working through Haskell Programming From First Principles. Then I would work through Scala With Cats, Essential Effects, and Practical FP in Scala for how all of that maps onto Scala.

Practical FP in Scala

BTW for learning good application structure with Tagless Final I really recommend the book Practical FP in Scala and its work-along example application. That's where I stole the pattern above from.
