# Next.js TypeScript Rules

## Component Patterns

- Use functional components exclusively
- Extract custom hooks for shared logic
- Keep components under 150 lines
- Use Server Components by default, Client Components only when needed

## File Naming

- Components: PascalCase (UserProfile.tsx)
- Utilities: camelCase (formatDate.ts)
- API routes: route.ts in app/api/

## State Management

- Server state: React Query / SWR
- Client state: Zustand (not Redux)
- Form state: React Hook Form + Zod

## Styling

- Tailwind CSS utility classes
- No inline styles or CSS modules
- Use cn() for conditional classes
