In this talk, we will start with the basics, understanding what build caching is and why it can be a bit tricky to handle in real projects. Looking at a quick history of build caching in Scala, we will see how it has evolved and how you can leverage existing build caching capabilities in sbt today. I’ll share some practical insights on making the most of build caching when using sbt. Finally, we’ll look at what the future holds for build caching with sbt 1 and 2 and see how you can prepare for it.
I would like to go over the most relevant tools and changes that can improve your developer experience.
I propose that we can extend Mirrors to operations, and use the most natural DSL of all - plain trait definitions.
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.
Join me for a fun and possibly opinionated talk about the state of Scala and other JVM languages.
