Generate gRPC and Go service code

Generate Go code from Proto definitions

Generating gRPC and HTTP stubs with validation and Swagger docs in one command—avoids manual interface coding.

• · Service name (e.g., ping-service)
• · Version (e.g., v1)
• · Proto file path

• · *.pb.go (messages)
• · *.grpc.pb.go (gRPC)
• · *.http.pb.go (HTTP)
• · *.validate.go (validation)
• · *.swagger.json (API docs)

• · protoc compiler
• · Go plugins (protoc-gen-go, protoc-gen-go-grpc, protoc-gen-go-http, protoc-gen-validate, protoc-gen-openapiv2)

• · Proto files written
• · protoc installed
• · Go 1.18+
• · Make targets defined

• · Protoc plugin missing
• · Proto syntax error
• · Import path incorrect
• · Swagger generation fails

• · HTTP and gRPC dual codegen
• · Built-in validation code
• · Swagger auto-generation
• · Make target encapsulation
