About grpc-gateway
gRPC Gateway is a plugin for protoc , the Google protocol buffers compiler. It reads protobuf service definitions and generates a reverse proxy server that translates a RESTful HTTP API into gRPC. The generated server follows the google.api.http annotations attached to those service definitions, so a single set of protobuf services can be exposed in both gRPC and RESTful style at the same time. It lives in the gRPC ecosystem, is written in Go, and is distributed under the BSD 3 Clause license.
