Kévin Rauscher at #ScalaUA - Scala Schemas with Shapeless

Kévin Rauscher explains how to use Shapeless to automatically derive typeclasses and case class transformers, reducing boilerplate.

Kévin Rauscher at #ScalaUA - Scala Schemas with Shapeless Why write code the compiler can generate for us? Following this motto, we, as scala developers, tend to derive a lot of things from our model definition. But what happens when we have to keep our API backward compatible while upgrading our domain model. While coupling models are inconvenient, decoupling them leads to a lot of boilerplate. In this talk, we'll see that, by using the same techniques which allow us to automatically generate our typeclasses, we can also scrap the boilerplate when going from one model to another. In this session, expect to hear about: - Recursion and pattern matching - HList and LabelledGenerics - Automatic Derivation of typeclasses - Automatic Derivation of case class transformers Follow ScalaUA Conference on Twitter: twitter.com/@ScalaUA_Conf
