  • Automatic error logging and tracking

🎨 User Interface

  • Beautiful, animated error screen with Framer Motion
  • Mobile-responsive design
  • Accessibility-focused with proper ARIA labels
  • Error recovery options (Try Again / Go Home)

🔍 Development Features

  • Detailed error information in development mode
  • Component stack traces for debugging
  • Unique error ID generation for tracking
  • Console error logging with grouped output

📊 Production Features

  • User-friendly error messages
  • Error ID for support tickets
  • Hooks for external error reporting services
  • Minimal error exposure for security

Error Boundary Features

Error Recovery

  • Try Again: Resets error state and re-renders components
  • Go Home: Redirects to homepage for fresh start
  • Auto-recovery: Component state reset on retry

Error Tracking

  • Unique error IDs: ERR-{timestamp}-{random}
  • Console logging in development
  • Production error reporting hooks
  • Component stack traces

UI Components

  • Animated error icon and messages
  • Loading states during recovery
  • Mobile-responsive layout
  • Accessible error information

Usage

Basic Usage

import ErrorBoundary from './components/ErrorBoundary';

function App() {
  return (
    <ErrorBoundary>
      <YourAppComponents />
    </ErrorBoundary>
  );
}

With Custom Props

<ErrorBoundary>
  <ChildComponents />
</ErrorBoundary>

Error Handling Flow

  1. Error Occurs: React component throws an error
  2. Error Boundary Catches: componentDidCatch is triggered
  3. State Update: Error state is set with error details
  4. Fallback UI: Beautiful error screen is displayed
  5. User Action: User can retry or navigate away
  6. Recovery: Error state is reset and app continues

Development vs Production

Development Mode

  • Shows detailed error messages
  • Displays component stack traces
  • Console error logging
  • Error details expandable section

Production Mode

  • User-friendly error messages
  • Error ID for support
  • No sensitive error exposure
  • Clean, professional UI

Testing

The Error Boundary includes comprehensive tests covering:

  • Normal rendering without errors
  • Error catching and fallback UI
  • Error state recovery
  • Development mode features
  • Console logging verification

Run tests with:

npm test ErrorBoundary

Integration Notes

Store Integration

The Error Boundary works seamlessly with:

  • Zustand state management
  • Wallet connection states
  • Loading and error states from stores

Styling Integration

Uses existing design system:

  • Tailwind CSS classes
  • Framer Motion animations
  • Lucide React icons
  • Custom UI components (Card, Button)

Best Practices

For Developers

  1. Wrap critical app sections with Error Boundaries
  2. Test error scenarios in development
  3. Monitor error IDs in production
  4. Implement external error reporting

For Users

  1. Clear error messages guide recovery
  2. Multiple recovery options available
  3. Error IDs help with support
  4. Graceful degradation maintains UX

Future Enhancements

Planned Features

  • External error reporting integration (Sentry, LogRocket)
  • Error analytics dashboard
  • Custom error message templates
  • Error boundary nesting for specific sections
  • Performance monitoring integration

Extensibility

The Error Boundary is designed to be easily extended with:

  • Custom error reporting services
  • Additional recovery actions
  • Custom styling themes
  • Error categorization

Support

For issues related to the Error Boundary:

  1. Check the error ID in the UI
  2. Review console logs in development
  3. Test with the provided test suite
  4. Refer to the component documentation
