Writing REST Services for the gRPC curious
summary
Demonstrates a reverse proxy that translates JSON HTTP calls into protobuf gRPC requests using the gRPC-Gateway, generated by a protoc plugin; generates an OpenAPI/Swagger UI, supports server-side streaming over REST, and maps protobuf well-known types (timestamps, wrappers, Struct) to JSON. Shows live edits: adding a field and a new GET method, regenerating code, and the proxy immediately serving the updated JSON API. Also demos automatic field mask translation for PATCH and a pluggable custom HTTP error formatter; the examples compile and run.
