I propose that we can extend Mirrors to operations, and use the most natural DSL of all - plain trait definitions.
Can we derive endpoints from just a trait definition? One of Scala's strengths is domain modelling, and from a data definition, we can derive generic information in a Mirror, e.g. to generate type classes. For operations (such as endpoints) there is less support from metaprogramming, so we often create DSLs to describe them. I propose that we can extend Mirrors to operations, and use the most natural DSL of all - plain trait definitions.
This presentation describes the development of a financial middleware that internationally connects several ERP systems (Navision and SAP) to a cloud-based invoicing solution.
This talk is my slightly expanded version of that statement, and should hopefully understand what "Free" is, what purpose it serves and where it came from.
In this talk, we will demonstrate some elegant applications of functional programming in Scala, with even more elegant visual results - all with live code and real-time output.
We managed to alleviate almost entirely the slowdown induced by Tapir in a web socket server. The journey towards this goal was quite insightful, and we would like to share it with you.
