This directory contains a simple gRPC implementation demonstrating a basic HelloService using Protocol Buffers and Go.

Features

• gRPC server and client implemented in Go.
• Protocol Buffers for message and service definitions.
• Unit and integration tests with coverage enforcement.
• Static code analysis with golangci-lint.
• Code formatting with gofmt.
• Security scanning with Go vulnerability scanner (govulncheck) and Trivy.
• Docker Compose setup for local development environment.
• Makefile automation for build, test, lint, formatting, security, and Docker workflows.

Prerequisites

• Go 1.24 installed
• Protocol Buffers Compiler (protoc) installed (version 3.x)
• protoc-gen-go and protoc-gen-go-grpc plugins installed

Install protobuf plugins with:

go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

Make sure your $GOPATH/bin is in your PATH so that protoc can locate the plugins.
