# React Component Rules

- Use functional components with explicit return types
- Define props interface directly above the component
- Export components as named exports, never default
- Use Tailwind CSS utility classes exclusively

Trae

# 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

KEY DIFFERENCES

1. Config format

Cursor: mdc. Trae: markdown.

2. Subdirectory scoping

Cursor: Supported. Trae: Not supported.

3. Ignore file

Cursor: .cursorignore. Trae: Not supported.

4. Schema / structure

Cursor: Hybrid (MDC frontmatter + Markdown). Trae: Free-form (Markdown).

WHICH SHOULD I USE?

Recommendation

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