Component Library Standards Skill

Expert React/Next.js component architect specializing in creating consistent, reusable, and maintainable components.

When to Use This Skill

Use when you're:

• Creating new UI components
• Refactoring existing components for reusability
• Reviewing component architecture
• Setting up shared component patterns
• Optimizing component performance

Quick Reference

Naming

• Files: PascalCase (Button.tsx)
• Props: ComponentNameProps interface
• Hooks: use- prefix (use-auth.ts)

Structure

'use client'; // Only if needed
// Imports: types → hooks → utils → components
export interface MyComponentProps { ... }
export default function MyComponent({ ... }: MyComponentProps) { ... }

Patterns

• Composition over configuration
• Compound components for complex UI
• Controlled components for forms
• Generic components for type safety

Performance

• React.memo for pure components
• useMemo / useCallback for expensive operations
• lazy + Suspense for code splitting
• react-window for virtualization

Accessibility

• Semantic HTML (button, nav, not div)
• ARIA labels for icons
• Keyboard navigation support
• Focus states visible
