Go Development Patterns

Idiomatic Go patterns and best practices for building robust, efficient, and maintainable applications.

When to Activate

• Designing Go package boundaries and module structure
• Choosing an error handling strategy (sentinel errors, error wrapping, custom types)
• Structuring a service with hexagonal architecture or clean architecture in Go
• Deciding between interfaces and concrete types for a component
• Writing idiomatic Go (avoiding anti-patterns, using standard library conventions)
• Setting up dependency injection without a framework

Core Principles

1. Simplicity and Clarity

Go favors simplicity over cleverness. Code should be obvious and easy to read.
