Quick Reference
Go Structure: Start simple (main.go, go.mod). Use internal/ for private code. Organize by domain not layer (internal/user/ not internal/handlers/). cmd/ for entry points. Flat packages, avoid deep nesting. Interfaces in consumer package. Tests next to implementation. Let structure emerge, don't over-engineer upfront.
Use When
- New Go projects
- Refactoring Go codebases
- Microservices in Go
- CLI applications
Skip When
- Tiny scripts (just main.go)
- Library-only packages
- Established project conventions
