Generic derivation based macros for JsonSchema type class of Scala endpoints library.

Endpoints have generic derivation of json schemas based on Shapeless library.

This project provides fully compatible, drop-in replacement that doesn't use Shapeless, but Scala macros directly. This approach has several advantages:

  • immediate compilation-time performance improvements
  • more descriptive error messages
  • no runtime overhead as materialization to HList/Coproduct is not required
  • avoided runtime dependency on Shapeless

However, be noticed that this is experimental project.

Getting started

To get started, first add project dependency to your build.sbt:

libraryDependencies += "io.scalaland" %% "endpoints-json-schema-macros" % "0.10.0"
