Structure React 19+ components following best practices for organization, state management, props handling, and code readability with top-down structure and single responsibility principle. Use this skill when creating new React components, refactoring existing components, organizing component logic, managing component state, defining prop interfaces (IComponentProps with I prefix), or implementing component patterns. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend component implementations. This skill ensures predictable top-down structure (imports → types/interfaces → component → hooks → derived values → JSX), proper props destructuring with defaults in function signature, manageable component size (split at >300 lines), composition via Shadcn Slot pattern (asChild prop), React 19 patterns (use() hook for promises, useActionState for forms, useOptimistic for immediate feedback), no manual useMemo/useCallback (React Compiler handles memoization), Server Compo

Frontend Components
When to use this skill:
When creating new React components with React 19+ features
When refactoring large components into smaller ones (>300 lines)
When organizing component structure and code order (top-down readability)
When defining component props with TypeScript interfaces (IComponentProps)
When implementing state management with useState, useOptimistic, or Zustand
When using composition patterns with Shadcn/ui Slot and asChild prop
When handling conditional rendering and early returns
When using React 19 Actions API (useActionState, useFormStatus) for forms
When using the use() hook to unwrap promises in Server Components
When extracting reusable component logic into custom hooks
When working on component files (.tsx, .jsx, components/.)
When reviewing component structure for readability (scroll test)
When deciding between local state, lifted state, or global state (Zustand)
When implementing optimistic UI updates with useOptimistic
This Skill provides Claude Code with specific guidance on how to adhere to coding standards as they relate to how it should handle frontend components.
