Magnolia: Generic Derivation 2.0

13th November 2017 in London at CodeNode

This SkillsCast was filmed at Magnolia: Generic Derivation 2.0

Skillscast coming soon.

London Scala User Group and ScalaX Bytes have come together for this event with long time Scala programmer Jon Pretty! Don't miss it!

In the last few years, typeclasses have become an increasingly popular tool for solving a wide variety of problems Scala developers encounter every day. But while typeclasses can be composed in entirely predictable ways from smaller primitive types to support larger abstract datatypes, there's no support offered from the language to do this.

For a while, Shapeless has been an admirable enabler, leveraging implicit search and a couple of macros to provide automatic derivations, but its approach to the problem is the cause of very slow compile times; the definitions needed to derive a typeclass are often verbose, type-heavy and complex; and, when derivation fails, the user gets no debugging feedback.

Magnolia basically fixes all of these problems.

Join us at ScalaX 2017 on 14-15th December for 2 days packed with talks, tutorials and discussions on Scala and the reactive platform!
