Build a production service with VirtusLab Scala Stack and AI
Piotr Janczyk

Build and ship a production-ready microservice in direct-style Scala 3: no Futures, no IO monads. Set up an HTTP API with Tapir, concurrency and resilience with Ox, a type-safe SQL layer, and an sttp client, with AI assistance throughout. Type-safe, Loom-powered, and refreshingly simple Scala.
