Using Components

When using components from the library, import them directly from their respective directories:

import { TextField, Button } from '@/components/common/form';
import { Card } from '@/components/common/data-display';
import { AppLayout } from '@/components/layout';

export default function MyPage() {
return (
  
    
      
      Submit
    
  
);
}

Component Best Practices

1. Use TypeScript Props Interfaces: Define clear prop interfaces for all components
2. Component Documentation: Include JSDoc comments for all components
3. Default Props: Provide sensible default props where applicable
4. Error Handling: Include proper error states and fallbacks
5. Accessibility: Ensure components meet WCAG accessibility standards
6. Responsive Design: Components should work across different screen sizes
7. Performance: Use React.memo for expensive components when appropriate

Creating New Components

When creating new components:

1. Place them in the appropriate directory based on their purpose
2. Create a clear and concise TypeScript interface for props
3. Include comprehensive JSDoc documentation
4. Add appropriate test cases
5. Consider reusability and composability
