# React Component Standards

## Purpose
Ensure consistent React component patterns across the frontend codebase.

## Priority
High

## Instructions
- Use functional components with TypeScript
- Define props interfaces above the component
- Use React.FC only when children are expected
- Colocate styles using CSS Modules (*.module.css)
- Extract hooks into separate files when reused
- Memoize expensive computations with useMemo
- Use React.lazy for route-level code splitting

# React Component Conventions

- Use functional components with TypeScript interfaces for props
- Export components as named exports
- Use Tailwind CSS for all styling
- Keep components under 150 lines; extract sub-components when larger
