    Use Cases & Benefits

    • Generates a reverse-proxy server that translates RESTful HTTP JSON APIs into gRPC calls based on protobuf service definitions.
    • Enables simultaneous support for both gRPC and RESTful JSON APIs from a single protobuf service definition with minimal configuration.
    • Use for exposing gRPC services to clients that only support RESTful JSON APIs for backward compatibility or broader client support.
    • Use for generating OpenAPI (Swagger) specifications automatically from gRPC service definitions to document and test APIs.
    • Use for integrating gRPC services into existing HTTP/JSON infrastructure without modifying the original gRPC service implementation.

    From the README

    gRPC to JSON proxy generator following the gRPC HTTP spec

    The gRPC-Gateway is a plugin of the Google protocol buffers compiler protoc. It reads protobuf service definitions and generates a reverse-proxy server which translates a RESTful HTTP API into gRPC. This server is generated according to the google.api.http annotations in your service definitions.

    This helps you provide your APIs in both gRPC and RESTful style at the same time.
