What problem does it solve?

This Skill helps developers decide when to use TypeScript interfaces versus type aliases, reducing confusion and inconsistencies in type design.

Core Features & Use Cases

  • Clear guidance on object types vs non-object types, with rules for when to prefer interface or type.
  • Practical decision scenarios for API surfaces, component props, and library declarations.
  • Quick comparisons of declaration merging, unions, tuples, and mapped types to inform coding standards.

Quick Start

Decide, in your codebase, to use interface for object shapes that can be extended and type for unions, tuples, and mapped types.
