A problem that many people face as they learn functional programming is the disconnect between understanding individual FP concepts and understanding how to apply those concepts in real programs. Even after learning about type classes, Kleisli, State, etc., it can be hard to make the leap to designing and implementing a program in functional Scala.
In this talk I'll guide you through the design process for a domain-driven, functional application that exposes a REST API. Along the way we'll encounter challenges such as error handling, logging, passing context around, and making asynchronous requests to a backend service, and explore functional solutions for each of them.
We're still nailing down the details of our second speaker for the night. Watch this space for an annoucement very soon!
