go-practices

Quick Start

1. Follow hexagonal architecture: business logic in pkg/api/business/, adapters in pkg/api/adapters/
2. Use snake_case for all Go files
3. Wrap errors: fmt.Errorf("%w: %w", ErrSentinelError, err)
4. Run tests with race detection: go test -race ./...

Key Principles

• Business logic has NO external dependencies
• All external interactions through interfaces
• Composition via AppContext (composition root)
• Table-driven tests with t.Parallel()
• OpenTelemetry for observability
