Scale By The Bay 2018 Unconference: Devon Stewart
summary
Generates strongly typed Scala server and client code from OpenAPI/Swagger using a compile‑time sbt plugin so generated files are never committed; works with Akka HTTP and http4s, Circe for JSON, Cats and refined types, and exposes compiler errors when the spec changes. Uses guardrail code generator and Scala Meta AST to produce testable Handler traits, finds real security bugs during migration, and enforces five levels of CI tests while allowing gradual migration alongside handwritten routes.
