# TypeScript Project Rules

## Tech Stack
- TypeScript with strict mode
- [Framework: React/Next.js/Express/etc.]
- [Testing: Vitest/Jest]

## Commands
- `npm run dev` - Development
- `npm test` - Tests
- `npm run lint` - Linting
- `npm run typecheck` - Type checking

## Code Style
- Use named exports
- Prefer const arrow functions
- All functions must have explicit return types
- No `any` types - use `unknown` and narrow

## Gotchas
- [Add your project-specific gotchas]

## File Patterns
- Components: `src/components/[Name]/[Name].tsx`
- Hooks: `src/hooks/use[Name].ts`
- Types: `src/types/[name].ts`
