# React Component Rules

1. Use functional components with TypeScript interfaces for props
2. Prefer server components by default — add "use client" only for interactivity
3. Colocate component tests in adjacent __tests__/ directories
4. Use named exports, not default exports
5. Extract custom hooks into hooks/ directory when reused across components

## Styling
- Use Tailwind CSS v4 utility classes
- Follow mobile-first responsive design
- Keep component-specific styles colocated

## State Management
- Use React 19 use() for async data in server components
- Prefer URL state (searchParams) over client state where possible
- Use Zustand for complex client-side state

- React 19 with Server Components
- Tailwind CSS v4
- Drizzle ORM with PostgreSQL

## Code Style
- Prefer named exports over default exports
- Use "use client" directive only when interactivity is required
- Colocate tests in __tests__ directories next to source files
- Use Zod for all runtime validation

## Architecture
- App Router with nested layouts in app/
- Server actions in app/actions/
- Database schema in db/schema.ts
- Shared utilities in lib/

## Commands
- Dev server: pnpm dev

- Test: pnpm test
- Lint: pnpm lint

KEY DIFFERENCES

1. IDE integration

Trae: Supported. Zed: Editor.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Trae, configure .trae/rules/*.md. If you use Zed, configure .rules. Many projects include config files for multiple tools so each team member can use their preferred editor.
