Version: ZIO 2.x

Getting Started with ZIO Json


The goal of this project is to create the best all-round JSON library for Scala:

  • Performance to handle more requests per second than the incumbents, i.e. reduced operational costs.
  • Security to mitigate against adversarial JSON payloads that threaten the capacity of the server.
  • Fast Compilation no shapeless, no type astronautics.
  • Future-Proof, prepared for Scala 3 and next generation Java.
  • Simple small codebase, short and concise documentation that covers everything.
  • Helpful errors are readable by humans and machines.
  • ZIO Integration so nothing more is required.
