Maintaining separate implementations for gRPC and REST APIs leads to code drift and bugs, a problem gRPC-Gateway solves by using a single definition.
gRPC-Gateway acts as a reverse proxy that translates incoming HTTP/JSON requests into gRPC calls and translates the gRPC responses back to HTTP/JSON.
You can map HTTP routes to gRPC methods using inline proto annotations, an external YAML file, auto-generation, or multiple bindings for advanced use cases.
A step-by-step guide shows how to define a proto service, configure buff for code generation, implement the Go server, and run both gRPC and REST endpoints.
gRPC-Gateway supports advanced production features like custom URL path parameters, server-side streaming over HTTP, and automatic error code translation.
Using gRPC-Gateway saves significant time by providing a single source of truth for your APIs, ensuring consistency and generating OpenAPI documentation automatically.
