Go Development (1.25+)

Core Principles

• Stdlib first: External deps only when justified
• Concrete types: Define interfaces at consumer, return structs
• Composition: Over inheritance, always
• Fail fast: Clear errors with context
• Simple: The obvious solution is usually correct

Quick Patterns

Error Handling

if err := doThing(); err != nil {
    return fmt.Errorf("do thing: %w", err)
}
