a6-plugin-grpc-transcode

Overview

The grpc-transcode plugin converts HTTP/JSON requests into gRPC calls and returns gRPC responses as JSON. Clients send standard HTTP requests; APISIX transcodes them to gRPC using a pre-uploaded protobuf definition, forwards to the gRPC upstream, and returns the response as JSON. The gRPC service needs no modification.

When to Use

• Expose gRPC services via RESTful HTTP endpoints
• Allow browser/mobile clients to call gRPC services without gRPC client libraries
• Add HTTP API gateway features (auth, rate limiting, logging) to gRPC services
• Migrate from REST to gRPC incrementally
• Decode gRPC error details into human-readable JSON
