Introduction to gRPC with ScalaPB
summary
Quick, hands-on guide to using ScalaPB with gRPC: shows the sbt plugin and protoc setup, how generated Scala sources map to proto packages, and add sbt plugin and ScalaPB dependencies to enable codegen. Walks through concrete examples: unary calls returning Future, server-streaming, client-streaming and bi‑directional streaming using StreamObserver, plus blocking vs nonblocking stubs and Akka Streams integration. Explains ScalaPB customizations like protobuf wrappers for optional types and file/package options, and recommends keeping generated messages out of core models.
