## Intro

Cursor Rules Collection is a community-curated repository of .mdc rule files for 40+ technology stacks with 5,000+ GitHub stars. Each rule file is a structured set of coding conventions, patterns, and best practices that Cursor AI follows automatically when you place it in your project. Instead of repeating "use functional components" or "follow PEP 8" every conversation, write it once as a rule and Cursor remembers forever. Best for teams standardizing AI-generated code across projects. Works with: Cursor AI. Setup time: under 1 minute.

# 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
```

### Creating Custom Rules

```bash
mkdir -p .cursor/rules
cat > .cursor/rules/my-project.mdc << 'EOF'
---
description: My project conventions
globs: ["**/*.ts"]
alwaysApply: true
---

# Project Rules
- Always use snake_case for database columns
- API responses use camelCase
- All functions must have JSDoc comments
EOF
```

### Key Stats
- 5,000+ GitHub stars
- 40+ technology stacks covered
- 200+ community-contributed rules
- Compatible with Cursor AI .mdc format
- Browsable at cursor.directory
