6.2. Extending & Customizing

Adding New Features

1. Custom API Endpoints

   // backend/src/api/custom/routes/custom.ts
   export default {
     routes: [
       {
         method: 'GET',
         path: '/custom',
         handler: 'custom.findAll',
         config: {
           policies: ['isAuthenticated'],
           middlewares: ['rateLimit'],
         },
       },
     ],
   };
   

2. Frontend Features

   // frontend/src/components/custom/CustomFeature.tsx
   import { useCustomHook } from '@/hooks/useCustomHook';
   
   export const CustomFeature: React.FC = () => {
     const { data, loading } = useCustomHook();
     
     return (
       <div className="custom-feature">
         {loading ? (
           <LoadingSpinner />
         ) : (
           <FeatureContent data={data} />
         )}
       </div>
     );
   };

Integration Guidelines

1. Service Integration

   interface ServiceIntegration {
     init(): Promise<void>;
     connect(): Promise<boolean>;
     configure(config: Config): void;
     handleWebhook(payload: any): Promise<void>;
   }
   

2. Plugin Development

   // backend/src/plugins/custom-plugin/index.ts
   export default {
     register(strapi: Strapi) {
       strapi.customPlugin = {
         service: new CustomService(),
         controller: new CustomController(),
       };
     },
     bootstrap(strapi: Strapi) {
       // Plugin initialization
     },
   };

6.3. Troubleshooting & Debugging

Development Tools

1. Logging System

   interface Logger {
     levels: {
       ERROR: 0;
       WARN: 1;
       INFO: 2;
       DEBUG: 3;
     };
     transports: {
       console: ConsoleTransport;
       file: FileTransport;
     };
   }
   

2. Debugging Commands

   # Frontend debugging
   yarn dev:debug
   
   # Backend debugging
   yarn develop:debug
   
   # Docker debugging
   docker-compose logs -f [service]
   

Common Issues & Solutions

1. Docker Issues

   # Reset Docker environment
   docker-compose down -v
   docker system prune -f
   docker-compose up -d
   
   # Check container health
   docker ps --format "table {{.Names}}\t{{.Status}}"
   

2. Database Connection

   interface DatabaseTroubleshooting {
     checkConnection(): Promise<boolean>;
     validateSchema(): Promise<ValidationResult>;
     repairTables(): Promise<void>;
   }
   

3. Memory Issues

   # Check memory usage
   docker stats
   
   # Optimize Node.js memory
   export NODE_OPTIONS="--max-old-space-size=4096"

Performance Profiling

1. Frontend Profiling

   interface PerformanceProfile {
     metrics: {
       renderTime: number;
       componentUpdates: number;
       memoryUsage: number;
     };
     traces: {
       network: NetworkTrace[];
       rendering: RenderTrace[];
     };
   }
   

2. Backend Profiling

   interface APIProfile {
     responseTime: number;
     queryCount: number;
     cacheHits: number;
     memoryUsage: {
       before: number;
       after: number;
       diff: number;
     };
   }

Error Handling

1. Global Error Boundary

   class GlobalErrorBoundary extends React.Component {
     static getDerivedStateFromError(error: Error) {
       return { hasError: true, error };
     }
     
     componentDidCatch(error: Error, info: React.ErrorInfo) {
       logger.error('React Error Boundary:', { error, info });
     }
   }
   

2. API Error Handling

   interface APIError {
     code: string;
     message: string;
     details?: Record<string, any>;
     stack?: string;
   }
   
   class APIErrorHandler {
     handle(error: APIError): Response;
     log(error: APIError): void;
     notify(error: APIError): Promise<void>;
   }
