Go Backend Development for Microservices

Core Principles

• Apply Clean Architecture with clear separation into handlers, services, repositories, and domain models
• Prioritize interface-driven development with explicit dependency injection
• Write short, focused functions with a single responsibility
• Ensure safe use of goroutines, and guard shared state with channels or sync primitives

Project Structure

Maintain modular project structure with clear directories:

project/
├── cmd/           # Application entry points
├── internal/      # Private application code
├── pkg/           # Public library code
├── api/           # API definitions (OpenAPI, protobuf)
