Introduction to Smithy/Smithy4s
summary
Smithy is AWS’s IDL that separates business shapes from transport by using protocol-agnostic traits with built-in validators, and Smithy4s is a Scala code generator that generates case classes and interfaces whose core has no protocol dependencies. The demo shows SBT-driven codegen producing an implementation-to-http one-liner, a running HTTP server with Swagger UI served automatically, live error → status-code mapping, and a path toward pure-Scala cross-platform AWS SDKs (Dynamo client work-in-progress used at DisneyStreaming).
