Document component props

Component props define clear interfaces between parts of your application. By using TypeScript interfaces or types, you create simple, enforceable contracts for how components communicate. This structured approach helps both developers and AI systems understand component relationships without requiring extensive documentation or complex patterns. Well-defined prop interfaces serve as natural boundaries between components, making code more predictable and easier to maintain.

type ButtonProps = {
  onClick: () => void;
  children: React.ReactNode;
  variant?: 'primary' | 'secondary';
  disabled?: boolean;
}

type SearchBarProps = {
  onSearch: (query: string) => void;
  placeholder?: string;
  isLoading?: boolean;
}

Recommendation

Create concise prop interfaces that focus on essential data and behavior. Keep props simple and descriptive, using TypeScript to enforce type safety. While documentation and complex patterns have their place, starting with clear, well-typed props provides a solid foundation that can evolve with your application.
