Yaroslav Yaremenko shared a demo project called book-shelf
where he implemented a Lagom/Akka microservice on top of ZIO, with a GraphQL API powered by Caliban. He also used zio-grpc for service communication. A good example of mixing different technologies!
If you’re interested in using ZIO for building GUI, check out zio-swing
, a proof of concept wrapper around Swing that offers a functional interface.
