+- Clear prop interfaces with PropTypes validation
+- Easy to test and maintain
+
+## Error Handling
+
+### Error Boundaries
+- `ErrorBoundary` component for graceful error recovery
+- Development-friendly error details
+- User-friendly error messages
+
+### Offline Mode
+- Service status monitoring
+- Fallback data when services unavailable
+- Automatic retry mechanisms
+- Clear status indicators
+
+## Performance
+
+### Component Optimization
+- Smaller components = better React optimization
+- Reduced re-renders through focused components
+- Memoization opportunities for pure components
+
+### Code Splitting Ready
+- Modular structure supports code splitting
+- Easy to lazy load dashboard components
+- Clear separation enables tree shaking
+
+## Testing
+
+### Testable Components
+- Pure functions in utils
+- Isolated component logic
+- Clear prop interfaces
+- Mockable dependencies
+
+### Test Structure
+```javascript
+describe('SystemStatsCards', () => {
+  it('renders CPU usage correctly', () => {
+    // Test focused component
+  });
+});
+```

+
+#### **Service Level**
+- **API Gateway**: Core API, authentication, user management
+- **Service Adapters**: External service integrations
+- **API Docs**: Unified documentation aggregation
+- **Frontend**: User interface and experience
+
+#### **Component Level**
+- Each service has focused, single-purpose modules
+- Clear boundaries between layers (Controller, Service, Repository)
+- Minimal coupling between components
+
+### **2. Open/Closed Principle (OCP)**
+
+#### **Extensible Design**
+- Services can be extended without modification
+- Plugin architecture for new integrations
+- Configuration-driven service behavior
+- Easy addition of new microservices
+
+#### **Interface-Based Design**
+- Clear service interfaces
+- Standardized communication protocols
+- OpenAPI specifications for all services
+
+### **3. Dependency Inversion Principle (DIP)**
+
+#### **Service Dependencies**
+- Services depend on abstractions, not concretions
+- Database abstraction through repositories
+- Message bus abstraction through Redis
+- HTTP client abstraction through standardized libraries
+
+#### **Dependency Injection**
+- Spring Boot dependency injection (Java)
+- FastAPI dependency injection (Python)
+- Express middleware injection (Node.js)
+- React hooks for state management
+
+### **4. Interface Segregation Principle (ISP)**
+
+#### **Focused Interfaces**
+- Each service exposes only necessary endpoints
+- Clear API boundaries
+- Minimal service dependencies
+- Specific-purpose modules
+
+## 📊 **Service-Specific Implementations**
+
+### **API Gateway (Java Spring Boot)**
+
+#### **Clean Code Features**
+- **Layered Architecture**: Controller → Service → Repository
+- **Dependency Injection**: Constructor-based injection
+- **Validation**: Bean validation with proper error handling

+- **Error Handling**: Global exception handling
+
+#### **Key Improvements**
+```java
+// Before: Mixed concerns
+@RestController
+public class DashboardController {
+    @Autowired
+    private DashboardRepository repository;
+    
+    @GetMapping("/dashboards")
+    public List<Dashboard> getDashboards() {
+        return repository.findAll();
+    }
+}
+
+// After: Clean separation
+@RestController
+@RequestMapping("/api/dashboards")
+@Validated
+public class DashboardController {
+    private final DashboardService dashboardService;
+    
+    public DashboardController(DashboardService dashboardService) {
+        this.dashboardService = dashboardService;
+    }
+    
+    @GetMapping
+    @Operation(summary = "Get all dashboards")
+    public ResponseEntity<List<Dashboard>> getAllDashboards() {
+        List<Dashboard> dashboards = dashboardService.getAllDashboards();
+        return ResponseEntity.ok(dashboards);
+    }
+}
+```
+
+### **Service Adapters (Python FastAPI)**
+
+#### **Clean Code Features**
+- **Modular Structure**: Separated routes, models, services
+- **Type Safety**: Pydantic models with validation
+- **Async/Await**: Non-blocking operations

+
+#### **Clean Code Features**
+- **Single Purpose**: OpenAPI spec aggregation
+- **Error Handling**: Graceful degradation
+- **Caching**: Performance optimization
+- **Health Monitoring**: Service status tracking
+- **Configuration**: Environment-based settings
+
+#### **Key Improvements**
+```javascript
+// Before: Mixed concerns
+app.get('/openapi.json', async (req, res) => {
+  // All logic mixed together
+});
+
+// After: Clean separation
+const fetchServiceSpec = async (service) => { /* ... */ };
+const aggregateSpecs = (specs) => { /* ... */ };
+const checkServiceHealth = async (service) => { /* ... */ };
+
+app.get('/openapi.json', async (req, res) => {
+  try {
+    const specs = await fetchAllSpecs();
+    const aggregated = aggregateSpecs(specs);
+    res.json(aggregated);
+  } catch (error) {
+    handleError(error, res);
+  }
+});
+```
+
+### **Frontend (React)**
+
+#### **Clean Code Features**
+- **Component Composition**: Small, focused components
+- **Custom Hooks**: Reusable state logic
+- **Error Boundaries**: Graceful error handling
+- **Type Safety**: PropTypes validation
+- **Constants**: Centralized configuration
+
+#### **Key Improvements**
+```javascript
+// Before: Monolithic Dashboard (155 lines)
+// After: Composed components
+const Dashboard = () => {
+  return (
+    <div>
+      <ServiceStatusBanner serviceStatus={serviceStatus} />
+      <SystemStatsCards systemStats={systemStats} />
+      <ServiceStatusList services={services} />
+      <RecentEventsList events={events} />
+    </div>
+  );
+};
+```

+# Frontend Clean Code Implementation
+
+This document outlines the clean code principles and best practices implemented in the LabFusion frontend.
+
+## 🏗️ **Architecture Improvements**
+
+### **1. Separation of Concerns**
+- **Components**: UI-focused, single responsibility
+- **Hooks**: Business logic and state management
+- **Services**: API communication and data fetching
+- **Utils**: Pure functions and helper utilities
+- **Constants**: Configuration and static values
+
+### **2. Component Structure**
+```
+src/
+├── components/
+│   ├── common/           # Reusable UI components
+│   │   ├── ErrorBoundary.js
+│   │   ├── LoadingSpinner.js
+│   │   └── StatusIcon.js
+│   ├── dashboard/        # Dashboard-specific components
+│   │   ├── SystemStatsCards.js
+│   │   ├── ServiceStatusList.js
+│   │   └── RecentEventsList.js
+│   └── [main components]
+├── hooks/               # Custom React hooks
+├── services/            # API and external services
+├── utils/               # Utility functions
+└── constants/           # Configuration constants
+```
+
+## 🧹 **Clean Code Principles Applied**
+
+### **1. Single Responsibility Principle (SRP)**
+- Each component has one clear purpose
+- `SystemStatsCards` only handles system statistics display
+- `ServiceStatusList` only manages service status display
+- `StatusIcon` only renders status icons
+
+### **2. Don't Repeat Yourself (DRY)**
+- **StatusIcon**: Centralized status icon logic
+- **LoadingSpinner**: Reusable loading component
+- **Error handling**: Centralized in `utils/errorHandling.js`
+- **Constants**: All magic numbers and strings extracted
+
+### **3. Open/Closed Principle**
+- Components accept props for customization
+- Easy to extend without modifying existing code
+- StatusIcon supports different sizes and statuses
+
+### **4. Interface Segregation**
+- Small, focused prop interfaces
+- Components only receive what they need
+- Clear PropTypes definitions
+
+## 📝 **Code Quality Improvements**
+
+### **1. Constants Management**
+```javascript
+// Before: Magic numbers scattered
+timeout: 5000,
+marginBottom: 16,
+color: '#52c41a'
+
+// After: Centralized constants
+timeout: API_CONFIG.TIMEOUT,
+marginBottom: UI_CONSTANTS.MARGIN_BOTTOM,
+color: COLORS.SUCCESS
+```
+
+### **2. Error Handling**
+```javascript
+// Before: Inline error handling
+if (error.code === 'ECONNABORTED') {
+  return { error: 'Request timeout...' };
+}
+
+// After: Centralized error handling
+return handleRequestError(error);
+```
+
+### **3. Component Composition**
+```javascript
+// Before: Large monolithic component (155 lines)
+const Dashboard = () => {
+  // All logic mixed together
+};
+
+// After: Composed of smaller components
+const Dashboard = () => {
+  return (
+    <div>
+      <SystemStatsCards systemStats={systemStats} />
+      <ServiceStatusList services={services} />
+      <RecentEventsList events={events} />
+    </div>
+  );
+};
+```
+
+### **4. Type Safety**
+```javascript
+// PropTypes for better development experience
+SystemStatsCards.propTypes = {
+  systemStats: PropTypes.shape({
+    cpu: PropTypes.number,
+    memory: PropTypes.number,
+    disk: PropTypes.number,
+    network: PropTypes.number
+  }).isRequired
+};
+```
+
+## 🔧 **Utility Functions**
+
+### **1. Error Handling Utils**
+- `handleRequestError()`: Centralized API error handling
+- `determineServiceStatus()`: Service status calculation
+- `formatServiceData()`: Data transformation
+- `formatEventData()`: Event data formatting
+
+### **2. Reusable Components**
+- `StatusIcon`: Consistent status visualization
+- `LoadingSpinner`: Standardized loading states
+- `ErrorBoundary`: Graceful error handling
+
+## 📊 **Performance Improvements**
+
+### **1. Component Optimization**
+- Smaller components = better React optimization
+- Reduced re-renders through focused components
+- Memoization opportunities for pure components
+
+### **2. Code Splitting Ready**
+- Modular structure supports code splitting
+- Easy to lazy load dashboard components
+- Clear separation enables tree shaking
+
+## 🧪 **Testing Benefits**
+
+### **1. Testable Components**
+- Pure functions in utils
+- Isolated component logic
+- Clear prop interfaces
+- Mockable dependencies
+
+### **2. Test Structure**
+```javascript
+// Easy to test individual components
+describe('SystemStatsCards', () => {
+  it('renders CPU usage correctly', () => {
+    // Test focused component
+  });
+});
+```
+
+## 📈 **Maintainability Improvements**
+
+### **1. Readability**
+- Clear component names
+- Descriptive function names
+- Consistent code structure
+- Well-organized imports
+
+### **2. Extensibility**
+- Easy to add new status types
+- Simple to extend with new metrics
+- Clear patterns for new components
+
+### **3. Debugging**
+- Error boundaries catch issues
+- Clear error messages
+- Development-friendly error details
+- Centralized logging
+
+## 🎯 **Best Practices Implemented**
+
+### **1. React Best Practices**
+- Functional components with hooks
+- Proper prop validation
+- Error boundaries for error handling
+- Consistent naming conventions
+
+### **2. JavaScript Best Practices**
+- Pure functions where possible
+- Immutable data handling
+- Consistent error handling
+- Clear variable names
+
+### **3. CSS Best Practices**
+- Consistent spacing system
+- Reusable style constants
+- Component-scoped styles
+- Responsive design patterns
+
+## 🚀 **Benefits Achieved**
+
+1. **Maintainability**: Easy to modify and extend
+2. **Readability**: Clear, self-documenting code
+3. **Testability**: Isolated, testable components
+4. **Reusability**: Modular, reusable components
+5. **Performance**: Optimized rendering and loading
+6. **Reliability**: Better error handling and recovery
+7. **Developer Experience**: Clear patterns and structure

+- **Automatic Retry**: Attempts to reconnect when services come back online
+
+### 2. Graceful Degradation
+- **Fallback Data**: Uses sample data when services are unavailable
+- **Error Handling**: Displays helpful error messages instead of crashes
+- **Loading States**: Shows loading indicators during data fetching
+
+### 3. Offline Mode
+- **Offline Banner**: Clear indication when all services are down
+- **Instructions**: Step-by-step guide to start backend services
+- **Retry Button**: Easy way to attempt reconnection
+
+### 4. Error Recovery
+- **Timeout Handling**: 5-second timeout for all API calls
+- **Connection Error Detection**: Distinguishes between different error types
+- **User-Friendly Messages**: Clear explanations of what's happening
+
+## Service Status States
+
+### Online
+- All services are running normally
+- No status banner shown
+- Full functionality available
+
+### Partial
+- Some services are unavailable
+- Warning banner with service details
+- Limited functionality with fallback data
+
+### Offline
+- All backend services are down
+- Offline mode banner with instructions
+- Frontend runs with sample data only
+
+## API Configuration
+
+The frontend automatically detects service availability:
+
+```javascript
+// Service URLs (configurable via environment variables)
+API_GATEWAY_URL=http://localhost:8080
+SERVICE_ADAPTERS_URL=http://localhost:8000
+API_DOCS_URL=http://localhost:8083
+```
+
+## Development
+
+### Running Frontend Only
+```bash
+cd frontend
+npm install
+npm start
+```
+
+The frontend will start and show offline mode until backend services are started.
+
+### Testing Resilience
+1. Start frontend: `npm start`
+2. Observe offline mode banner
+3. Start backend: `docker-compose up -d`
+4. Watch automatic reconnection
+5. Stop backend services to test fallback
+
+## Error Messages
+
+- **Connection Timeout**: "Request timeout - service may be unavailable"
+- **Service Error**: "Service error: [HTTP status]"
+- **Service Unavailable**: "Service unavailable - check if backend is running"
+- **Unknown Error**: "Unknown error occurred"
+
+## Benefits
+
+- **Developer Experience**: Frontend can be developed independently
+- **User Experience**: Clear feedback about service status
+- **Debugging**: Easy to identify which services are having issues
+- **Reliability**: App doesn't crash when services are down

+# API Documentation Service Clean Code Implementation
+
+This document outlines the clean code principles and best practices implemented in the LabFusion API Documentation service (Node.js Express).
+
+## 🏗️ **Architecture Overview**
+
+The API Documentation service follows a modular architecture with clear separation of concerns:
+
+```
+api-docs/
+├── server.js          # Express application entry point
+├── package.json       # Dependencies and scripts
+├── Dockerfile         # Production container
+├── Dockerfile.dev     # Development container
+└── README.md         # Service documentation
+```
+
+## 🧹 **Clean Code Principles Applied**
+
+### **1. Single Responsibility Principle (SRP)**
+
+#### **Service Purpose**
+- **Primary**: Aggregates OpenAPI specifications from all services
+- **Secondary**: Provides unified Swagger UI interface
+- **Tertiary**: Monitors service health and availability
+
+#### **Function Responsibilities**
+- `fetchServiceSpec()`: Only fetches OpenAPI spec from a single service
+- `aggregateSpecs()`: Only combines multiple specs into one
+- `setupSwaggerUI()`: Only configures Swagger UI
+- `checkServiceHealth()`: Only monitors service health
+
+### **2. Open/Closed Principle (OCP)**
+
+#### **Extensible Service Configuration**
+```javascript
+// Easy to add new services without modifying existing code
+const services = [
+  { name: 'api-gateway', url: 'http://api-gateway:8080', specPath: '/v3/api-docs' },
+  { name: 'service-adapters', url: 'http://service-adapters:8000', specPath: '/openapi.json' },
+  { name: 'api-docs', url: 'http://api-docs:8083', specPath: '/openapi.json' }
+  // New services can be added here
+];
+```
+
+#### **Configurable Endpoints**
+```javascript
+// Service URLs can be configured via environment variables
+const API_GATEWAY_URL = process.env.API_GATEWAY_URL || 'http://api-gateway:8080';
+const SERVICE_ADAPTERS_URL = process.env.SERVICE_ADAPTERS_URL || 'http://service-adapters:8000';
+```
+
+### **3. Dependency Inversion Principle (DIP)**
+
+#### **Abstraction-Based Design**
+```javascript
+// Depends on abstractions, not concrete implementations
+const fetchServiceSpec = async (service) => {
+  try {
+    const response = await axios.get(`${service.url}${service.specPath}`, {
+      timeout: 5000,
+      headers: { 'Accept': 'application/json' }
+    });
+    return { success: true, data: response.data };
+  } catch (error) {
+    return { success: false, error: error.message };
+  }
+};
+```
+
+#### **Interface-Based Service Communication**
+- Uses HTTP client abstraction (axios)
+- Service health checking through standard endpoints
+- OpenAPI specification standard
+
+### **4. Interface Segregation Principle (ISP)**
+
+#### **Focused API Endpoints**
+- `/health`: Only health checking
+- `/services`: Only service status
+- `/openapi.json`: Only OpenAPI specification
+- `/`: Only Swagger UI interface
+
+## 📝 **Code Quality Improvements**
+
+### **1. Naming Conventions**
+
+#### **Clear, Descriptive Names**
+```javascript
+// Good: Clear purpose
+const fetchServiceSpec = async (service) => { /* ... */ };
+const aggregateSpecs = (specs) => { /* ... */ };
+const checkServiceHealth = async (service) => { /* ... */ };
+
+// Good: Descriptive variable names
+const serviceHealthStatus = await checkServiceHealth(service);
+const aggregatedSpec = aggregateSpecs(validSpecs);
+```
+
+#### **Consistent Naming**
+- Functions: camelCase (e.g., `fetchServiceSpec`)
+- Variables: camelCase (e.g., `serviceHealthStatus`)
+- Constants: UPPER_SNAKE_CASE (e.g., `API_GATEWAY_URL`)
+- Objects: camelCase (e.g., `serviceConfig`)
+
+### **2. Function Design**
+
+#### **Small, Focused Functions**
+```javascript
+const fetchServiceSpec = async (service) => {
+  try {
+    const response = await axios.get(`${service.url}${service.specPath}`, {
+      timeout: 5000,
+      headers: { 'Accept': 'application/json' }
+    });
+    return { success: true, data: response.data };
+  } catch (error) {
+    console.error(`Failed to fetch spec from ${service.name}:`, error.message);
+    return { success: false, error: error.message };
+  }
+};
+```
+
+#### **Single Level of Abstraction**
+- Each function handles one concern
+- Error handling separated from business logic
+- Clear return values
+
+### **3. Error Handling**
+
+#### **Consistent Error Responses**
+```javascript
+const handleError = (error, res) => {
+  console.error('Error:', error);
+  res.status(500).json({
+    error: 'Internal server error',
+    message: error.message,
+    timestamp: new Date().toISOString()
+  });
+};
+```
+
+#### **Graceful Degradation**
+```javascript
+// If some services are unavailable, still serve available specs
+const validSpecs = specs.filter(spec => spec.success);
+if (validSpecs.length === 0) {
+  return res.status(503).json({
+    error: 'No services available',
+    message: 'All services are currently unavailable'
+  });
+}
+```
+
+### **4. Configuration Management**
+
+#### **Environment-Based Configuration**
+```javascript
+const config = {
+  port: process.env.PORT || 8083,
+  apiGatewayUrl: process.env.API_GATEWAY_URL || 'http://api-gateway:8080',
+  serviceAdaptersUrl: process.env.SERVICE_ADAPTERS_URL || 'http://service-adapters:8000',
+  apiDocsUrl: process.env.API_DOCS_URL || 'http://api-docs:8083'
+};
+```
+
+#### **Centralized Configuration**
+- All configuration in one place
+- Environment variable support
+- Default values for development
+
+## 🔧 **Express.js Best Practices**
+
+### **1. Middleware Usage**
+
+#### **Appropriate Middleware**
+```javascript
+app.use(cors());
+app.use(express.json());
+app.use(express.static('public'));
+
+// Error handling middleware
+app.use((error, req, res, next) => {
+  handleError(error, res);
+});
+```
+
+#### **CORS Configuration**
+```javascript
+app.use(cors({
+  origin: process.env.ALLOWED_ORIGINS?.split(',') || ['http://localhost:3000'],
+  credentials: true
+}));
+```
+
+### **2. Route Organization**
+
+#### **Clear Route Structure**
+```javascript
+// Health check endpoint
+app.get('/health', (req, res) => {
+  res.json({
+    status: 'healthy',
+    timestamp: new Date().toISOString(),
+    uptime: process.uptime()
+  });
+});
+
+// Service status endpoint
+app.get('/services', async (req, res) => {
+  try {
+    const serviceStatuses = await Promise.allSettled(
+      services.map(service => checkServiceHealth(service))
+    );
+    // Process and return statuses
+  } catch (error) {
+    handleError(error, res);
+  }
+});
+```
+
+#### **RESTful Endpoints**
+- GET `/health`: Health check
+- GET `/services`: Service status
+- GET `/openapi.json`: OpenAPI specification
+- GET `/`: Swagger UI
+
+### **3. Async/Await Usage**
+
+#### **Proper Async Handling**
+```javascript
+app.get('/openapi.json', async (req, res) => {
+  try {
+    const specs = await Promise.allSettled(
+      services.map(service => fetchServiceSpec(service))
+    );
+    
+    const validSpecs = specs
+      .filter(result => result.status === 'fulfilled' && result.value.success)
+      .map(result => result.value.data);
+    
+    if (validSpecs.length === 0) {
+      return res.status(503).json({
+        error: 'No services available',
+        message: 'All services are currently unavailable'
+      });
+    }
+    
+    const aggregatedSpec = aggregateSpecs(validSpecs);
+    res.json(aggregatedSpec);
+  } catch (error) {
+    handleError(error, res);
+  }
+});
+```
+
+## 📊 **Data Processing Best Practices**
+
+### **1. OpenAPI Specification Aggregation**
+
+#### **Clean Spec Processing**
+```javascript
+const aggregateSpecs = (specs) => {
+  const aggregated = {
+    openapi: '3.0.0',
+    info: {
+      title: 'LabFusion API',
+      description: 'Unified API documentation for all LabFusion services',
+      version: '1.0.0'
+    },
+    servers: [],
+    paths: {},
+    components: {
+      schemas: {},
+      securitySchemes: {}
+    }
+  };
+  
+  specs.forEach(spec => {
+    // Merge paths with service prefix
+    Object.entries(spec.paths || {}).forEach(([path, methods]) => {
+      const prefixedPath = `/${spec.info?.title?.toLowerCase().replace(/\s+/g, '-')}${path}`;
+      aggregated.paths[prefixedPath] = methods;
+    });
+    
+    // Merge components
+    if (spec.components?.schemas) {
+      Object.assign(aggregated.components.schemas, spec.components.schemas);
+    }
+  });
+  
+  return aggregated;
+};
+```
+
+### **2. Service Health Monitoring**
+
+#### **Robust Health Checking**
+```javascript
+const checkServiceHealth = async (service) => {
+  try {
+    const response = await axios.get(`${service.url}/health`, {
+      timeout: 5000,
+      headers: { 'Accept': 'application/json' }
+    });
+    
+    return {
+      name: service.name,
+      status: 'healthy',
+      responseTime: response.headers['x-response-time'] || 'unknown',
+      lastCheck: new Date().toISOString()
+    };
+  } catch (error) {
+    return {
+      name: service.name,
+      status: 'unhealthy',
+      error: error.message,
+      lastCheck: new Date().toISOString()
+    };
+  }
+};
+```
+
+## 🚀 **Performance Optimizations**
+
+### **1. Caching Strategy**
+```javascript
+// Simple in-memory caching for OpenAPI specs
+let cachedSpec = null;
+let lastFetch = 0;
+const CACHE_DURATION = 5 * 60 * 1000; // 5 minutes
+
+app.get('/openapi.json', async (req, res) => {
+  const now = Date.now();
+  
+  if (cachedSpec && (now - lastFetch) < CACHE_DURATION) {
+    return res.json(cachedSpec);
+  }
+  
+  // Fetch fresh spec
+  const spec = await fetchAndAggregateSpecs();
+  cachedSpec = spec;
+  lastFetch = now;
+  
+  res.json(spec);
+});
+```
+
+### **2. Error Handling**
+```javascript
+// Global error handler
+process.on('unhandledRejection', (reason, promise) => {
+  console.error('Unhandled Rejection at:', promise, 'reason:', reason);
+});
+
+process.on('uncaughtException', (error) => {
+  console.error('Uncaught Exception:', error);
+  process.exit(1);
+});
+```
+
+### **3. Resource Management**
+```javascript
+// Graceful shutdown
+process.on('SIGTERM', () => {
+  console.log('SIGTERM received, shutting down gracefully');
+  server.close(() => {
+    console.log('Process terminated');
+  });
+});
+```
+
+## 🧪 **Testing Strategy**
+
+### **1. Unit Testing**
+```javascript
+// tests/server.test.js
+const request = require('supertest');
+const app = require('../server');
+
+describe('API Documentation Service', () => {
+  test('GET /health should return healthy status', async () => {
+    const response = await request(app).get('/health');
+    expect(response.status).toBe(200);
+    expect(response.body.status).toBe('healthy');
+  });
+  
+  test('GET /services should return service statuses', async () => {
+    const response = await request(app).get('/services');
+    expect(response.status).toBe(200);
+    expect(Array.isArray(response.body)).toBe(true);
+  });
+});
+```
+
+### **2. Integration Testing**
+```javascript
+test('GET /openapi.json should return aggregated spec', async () => {
+  const response = await request(app).get('/openapi.json');
+  expect(response.status).toBe(200);
+  expect(response.body.openapi).toBe('3.0.0');
+  expect(response.body.info.title).toBe('LabFusion API');
+});
+```

+# API Gateway Clean Code Implementation
+
+This document outlines the clean code principles and best practices implemented in the LabFusion API Gateway service (Java Spring Boot).
+
+## 🏗️ **Architecture Overview**
+
+The API Gateway follows a layered architecture with clear separation of concerns:
+
+```
+src/main/java/com/labfusion/
+├── config/          # Configuration classes
+├── controller/      # REST controllers (Presentation Layer)
+├── service/         # Business logic (Service Layer)
+├── repository/      # Data access (Repository Layer)
+├── model/          # JPA entities (Domain Layer)
+└── LabFusionApiGatewayApplication.java
+```
+
+## 🧹 **Clean Code Principles Applied**
+
+### **1. Single Responsibility Principle (SRP)**
+
+#### **Controllers**
+- **DashboardController**: Only handles dashboard-related HTTP requests
+- **SystemController**: Only manages system metrics and events
+- Each controller has a single, well-defined responsibility
+
+#### **Services**
+- **DashboardService**: Manages dashboard business logic
+- Each service class focuses on one domain area
+
+#### **Repositories**
+- **DashboardRepository**: Only handles dashboard data operations
+- **EventRepository**: Only manages event data persistence
+- Clear data access boundaries
+
+### **2. Open/Closed Principle (OCP)**
+
+#### **Extensible Design**
+```java
+// Easy to extend with new widget types
+public enum WidgetType {
+    CHART, TABLE, STATUS_CARD, METRIC
+}
+
+// Easy to add new dashboard configurations
+@Configuration
+public class OpenApiConfig {
+    // Open for extension, closed for modification
+}
+```
+
+#### **Interface-Based Design**
+```java
+public interface DashboardRepository extends JpaRepository<Dashboard, Long> {
+    // Interface allows for different implementations
+}
+```
+
+### **3. Dependency Inversion Principle (DIP)**
+
+#### **Dependency Injection**
+```java
+@Service
+public class DashboardService {
+    private final DashboardRepository dashboardRepository;
+    
+    // Constructor injection - depends on abstraction
+    public DashboardService(DashboardRepository dashboardRepository) {
+        this.dashboardRepository = dashboardRepository;
+    }
+}
+```
+
+### **4. Interface Segregation Principle (ISP)**
+
+#### **Focused Interfaces**
+- Each repository interface only contains methods relevant to its entity
+- Controllers only expose necessary endpoints
+- Services have focused, cohesive interfaces
+
+## 📝 **Code Quality Improvements**
+
+### **1. Naming Conventions**
+
+#### **Clear, Descriptive Names**
+```java
+// Good: Clear purpose
+public class DashboardController
+public class SystemController
+public class DashboardService
+
+// Good: Descriptive method names
+public List<Dashboard> getAllDashboards()
+public Dashboard createDashboard(Dashboard dashboard)
+public void deleteDashboard(Long id)
+```
+
+#### **Consistent Naming**
+- Classes: PascalCase (e.g., `DashboardController`)
+- Methods: camelCase (e.g., `getAllDashboards`)
+- Variables: camelCase (e.g., `dashboardRepository`)
+- Constants: UPPER_SNAKE_CASE (e.g., `API_VERSION`)
+
+### **2. Method Design**
+
+#### **Small, Focused Methods**
+```java
+@GetMapping("/dashboards")
+public ResponseEntity<List<Dashboard>> getAllDashboards() {
+    List<Dashboard> dashboards = dashboardService.getAllDashboards();
+    return ResponseEntity.ok(dashboards);
+}
+
+@PostMapping("/dashboards")
+public ResponseEntity<Dashboard> createDashboard(@RequestBody Dashboard dashboard) {
+    Dashboard createdDashboard = dashboardService.createDashboard(dashboard);
+    return ResponseEntity.status(HttpStatus.CREATED).body(createdDashboard);
+}
+```
+
+#### **Single Level of Abstraction**
+- Controller methods handle HTTP concerns only
+- Business logic delegated to service layer
+- Data access delegated to repository layer
+
+### **3. Error Handling**
+
+#### **Centralized Exception Handling**
+```java
+@ControllerAdvice
+public class GlobalExceptionHandler {
+    
+    @ExceptionHandler(EntityNotFoundException.class)
+    public ResponseEntity<ErrorResponse> handleEntityNotFound(EntityNotFoundException ex) {
+        ErrorResponse error = new ErrorResponse("Entity not found", ex.getMessage());
+        return ResponseEntity.status(HttpStatus.NOT_FOUND).body(error);
+    }
+}
+```
+
+#### **Consistent Error Responses**
+- Standardized error response format
+- Appropriate HTTP status codes
+- Clear error messages
+
+### **4. Configuration Management**
+
+#### **Externalized Configuration**
+```yaml
+# application.yml
+spring:
+  datasource:
+    url: ${DATABASE_URL:jdbc:postgresql://localhost:5432/labfusion}
+    username: ${DATABASE_USERNAME:labfusion}
+    password: ${DATABASE_PASSWORD:password}
+```
+
+#### **Environment-Specific Settings**
+- Development, staging, production configurations
+- Environment variable support
+- Sensitive data externalized
+
+## 🔧 **Spring Boot Best Practices**
+
+### **1. Annotation Usage**
+
+#### **Appropriate Annotations**
+```java
+@RestController
+@RequestMapping("/api/dashboards")
+@Validated
+public class DashboardController {
+    
+    @GetMapping
+    @Operation(summary = "Get all dashboards")
+    @ApiResponses(value = {
+        @ApiResponse(responseCode = "200", description = "Successfully retrieved dashboards"),
+        @ApiResponse(responseCode = "500", description = "Internal server error")
+    })
+    public ResponseEntity<List<Dashboard>> getAllDashboards() {
+        // Implementation
+    }
+}
+```
+
+### **2. Validation**
+
+#### **Input Validation**
+```java
+@PostMapping("/dashboards")
+public ResponseEntity<Dashboard> createDashboard(
+    @Valid @RequestBody Dashboard dashboard) {
+    // @Valid ensures input validation
+}
+```
+
+#### **Entity Validation**
+```java
+@Entity
+@Table(name = "dashboards")
+public class Dashboard {
+    
+    @NotBlank(message = "Name is required")
+    @Size(max = 100, message = "Name must not exceed 100 characters")
+    private String name;
+    
+    @NotNull(message = "User ID is required")
+    private Long userId;
+}
+```
+
+### **3. OpenAPI Documentation**
+
+#### **Comprehensive API Documentation**
+```java
+@Tag(name = "Dashboard Management", description = "Operations related to dashboard management")
+@RestController
+public class DashboardController {
+    
+    @Operation(summary = "Get all dashboards", description = "Retrieve all dashboards for the authenticated user")
+    @ApiResponses(value = {
+        @ApiResponse(responseCode = "200", description = "Successfully retrieved dashboards"),
+        @ApiResponse(responseCode = "401", description = "Unauthorized"),
+        @ApiResponse(responseCode = "500", description = "Internal server error")
+    })
+    @GetMapping
+    public ResponseEntity<List<Dashboard>> getAllDashboards() {
+        // Implementation
+    }
+}
+```
+
+## 📊 **Data Layer Best Practices**
+
+### **1. JPA Entity Design**
+
+#### **Clean Entity Structure**
+```java
+@Entity
+@Table(name = "dashboards")
+public class Dashboard {
+    
+    @Id
+    @GeneratedValue(strategy = GenerationType.IDENTITY)
+    private Long id;
+    
+    @NotBlank
+    @Size(max = 100)
+    private String name;
+    
+    @ManyToOne(fetch = FetchType.LAZY)
+    @JoinColumn(name = "user_id")
+    private User user;
+    
+    @OneToMany(mappedBy = "dashboard", cascade = CascadeType.ALL, orphanRemoval = true)
+    private List<Widget> widgets = new ArrayList<>();
+    
+    // Constructors, getters, setters
+}
+```
+
+#### **Proper Relationships**
+- Lazy loading for performance
+- Cascade operations where appropriate
+- Orphan removal for cleanup
+
+### **2. Repository Design**
+
+#### **Focused Repository Methods**
+```java
+@Repository
+public interface DashboardRepository extends JpaRepository<Dashboard, Long> {
+    
+    List<Dashboard> findByUserId(Long userId);
+    List<Dashboard> findByNameContainingIgnoreCase(String name);
+    Optional<Dashboard> findByIdAndUserId(Long id, Long userId);
+}
+```
+
+## 🚀 **Performance Optimizations**
+
+### **1. Database Optimization**
+- Lazy loading for relationships
+- Proper indexing strategies
+- Query optimization
+
+### **2. Caching Strategy**
+- Service-level caching where appropriate
+- Redis integration for distributed caching
+- Cache invalidation strategies
+
+### **3. Connection Pooling**
+- HikariCP configuration
+- Proper connection pool sizing
+- Connection timeout handling
+
+## 🧪 **Testing Strategy**

+### **1. Unit Testing**
+- Service layer unit tests
+- Repository layer tests
+- Controller layer tests
+
+### **2. Integration Testing**
+- Database integration tests
+- API integration tests
+- End-to-end testing
+
+### **3. Test Structure**
+```java
+@ExtendWith(MockitoExtension.class)
+class DashboardServiceTest {
+    
+    @Mock
+    private DashboardRepository dashboardRepository;
+    
+    @InjectMocks
+    private DashboardService dashboardService;
+    
+    @Test
+    void shouldCreateDashboard() {
+        // Given
+        Dashboard dashboard = new Dashboard();
+        when(dashboardRepository.save(any(Dashboard.class))).thenReturn(dashboard);
+        
+        // When
+        Dashboard result = dashboardService.createDashboard(dashboard);
+        
+        // Then
+        assertThat(result).isNotNull();
+        verify(dashboardRepository).save(dashboard);
+    }
+}
+```

+# Service Adapters Clean Code Implementation
+
+This document outlines the clean code principles and best practices implemented in the LabFusion Service Adapters service (Python FastAPI).
+
+## 🏗️ **Architecture Overview**
+
+The Service Adapters follow a modular architecture with clear separation of concerns:
+
+```
+service-adapters/
+├── main.py              # FastAPI application entry point
+├── models/              # Pydantic schemas (Domain Layer)
+│   ├── __init__.py
+│   └── schemas.py
+├── routes/              # API endpoints (Presentation Layer)
+│   ├── __init__.py
+│   ├── general.py       # General endpoints
+│   ├── home_assistant.py # Home Assistant integration
+│   ├── frigate.py       # Frigate integration
+│   ├── immich.py        # Immich integration
+│   └── events.py        # Event management
+├── services/            # Business logic (Service Layer)
+│   ├── __init__.py
+│   ├── config.py        # Configuration management
+│   └── redis_client.py  # Redis connection
+├── requirements.txt     # Dependencies
+└── README.md           # Service documentation
+```
+
+## 🧹 **Clean Code Principles Applied**
+
+### **1. Single Responsibility Principle (SRP)**
+
+#### **Route Modules**
+- **general.py**: Only handles general endpoints (health, services, root)
+- **home_assistant.py**: Only manages Home Assistant integration
+- **frigate.py**: Only handles Frigate camera system integration
+- **immich.py**: Only manages Immich photo management integration
+- **events.py**: Only handles event publishing and retrieval
+
+#### **Service Modules**
+- **config.py**: Only manages service configurations
+- **redis_client.py**: Only handles Redis connections and operations
+
+#### **Model Modules**
+- **schemas.py**: Only contains Pydantic data models
+
+### **2. Open/Closed Principle (OCP)**
+
+#### **Extensible Route Design**
+```python
+# Easy to add new service integrations
+from fastapi import APIRouter
+
+router = APIRouter(prefix="/home-assistant", tags=["Home Assistant"])
+
+# New integrations can be added without modifying existing code
+# Just create new route files and include them in main.py
+```
+
+#### **Configurable Services**
+```python
+# services/config.py
+SERVICES = {
+    "home_assistant": {
+        "name": "Home Assistant",
+        "url": os.getenv("HOME_ASSISTANT_URL", "http://homeassistant.local:8123"),
+        "token": os.getenv("HOME_ASSISTANT_TOKEN"),
+        "enabled": True
+    }
+    # Easy to add new services
+}
+```
+
+### **3. Dependency Inversion Principle (DIP)**
+
+#### **Dependency Injection**
+```python
+# main.py
+from services.redis_client import get_redis_client
+
+app.include_router(general_router, dependencies=[Depends(get_redis_client)])
+app.include_router(home_assistant_router, dependencies=[Depends(get_redis_client)])
+```
+
+#### **Interface-Based Design**
+```python
+# services/redis_client.py
+class RedisClient:
+    def __init__(self, redis_url: str):
+        self.redis_url = redis_url
+        self.client = None
+    
+    async def connect(self):
+        # Implementation details hidden
+        pass
+```
+
+### **4. Interface Segregation Principle (ISP)**
+
+#### **Focused Route Groups**
+- Each route module only exposes endpoints relevant to its service
+- Clear API boundaries
+- Minimal dependencies between modules
+
+## 📝 **Code Quality Improvements**
+
+### **1. Naming Conventions**
+
+#### **Clear, Descriptive Names**
+```python
+# Good: Clear purpose
+class ServiceStatus(BaseModel):
+    name: str
+    status: str
+    response_time: Optional[str] = None
+
+# Good: Descriptive function names
+async def get_home_assistant_entities()
+async def get_frigate_events()
+async def publish_event(event_data: EventData)
+```
+
+#### **Consistent Naming**
+- Classes: PascalCase (e.g., `ServiceStatus`, `EventData`)
+- Functions: snake_case (e.g., `get_home_assistant_entities`)
+- Variables: snake_case (e.g., `service_config`)
+- Constants: UPPER_SNAKE_CASE (e.g., `SERVICES`)
+
+### **2. Function Design**
+
+#### **Small, Focused Functions**
+```python
+@router.get("/entities")
+async def get_home_assistant_entities():
+    """Get all Home Assistant entities."""
+    try:
+        entities = await fetch_ha_entities()
+        return {"entities": entities}
+    except Exception as e:
+        logger.error(f"Error fetching HA entities: {e}")
+        raise HTTPException(status_code=500, detail="Failed to fetch entities")
+```
+
+#### **Single Level of Abstraction**
+- Route functions handle HTTP concerns only
+- Business logic delegated to service functions
+- Data validation handled by Pydantic models
+
+### **3. Error Handling**
+
+#### **Consistent Error Responses**
+```python
+try:
+    result = await some_operation()
+    return result
+except ConnectionError as e:
+    logger.error(f"Connection error: {e}")
+    raise HTTPException(status_code=503, detail="Service unavailable")
+except Exception as e:
+    logger.error(f"Unexpected error: {e}")
+    raise HTTPException(status_code=500, detail="Internal server error")
+```
+
+#### **Proper HTTP Status Codes**
+- 200: Success
+- 404: Not found
+- 503: Service unavailable
+- 500: Internal server error
+
+### **4. Data Validation**
+
+#### **Pydantic Models**
+```python
+class EventData(BaseModel):
+    event_type: str
+    service: str
+    timestamp: datetime
+    data: Dict[str, Any]
+    
+    class Config:
+        json_encoders = {
+            datetime: lambda v: v.isoformat()
+        }
+```
+
+#### **Input Validation**
+```python
+@router.post("/publish-event")
+async def publish_event(event_data: EventData):
+    # Pydantic automatically validates input
+    await redis_client.publish_event(event_data)
+    return {"message": "Event published successfully"}
+```
+
+## 🔧 **FastAPI Best Practices**
+
+### **1. Router Organization**
+
+#### **Modular Route Structure**
+```python
+# routes/home_assistant.py
+from fastapi import APIRouter, HTTPException, Depends
+from models.schemas import HAAttributes, HAEntity
+from services.redis_client import RedisClient
+
+router = APIRouter(prefix="/home-assistant", tags=["Home Assistant"])
+
+@router.get("/entities")
+async def get_entities(redis: RedisClient = Depends(get_redis_client)):
+    # Implementation
+```
+
+#### **Clear API Documentation**
+```python
+@router.get(
+    "/entities",
+    response_model=Dict[str, List[HAEntity]],
+    summary="Get Home Assistant entities",
+    description="Retrieve all entities from Home Assistant"
+)
+async def get_home_assistant_entities():
+    # Implementation
+```
+
+### **2. Dependency Injection**
+
+#### **Redis Client Injection**
+```python
+# services/redis_client.py
+async def get_redis_client() -> RedisClient:
+    redis = RedisClient(REDIS_URL)
+    await redis.connect()
+    return redis
+```
+
+#### **Service Configuration**
+```python
+# services/config.py
+def get_service_config(service_name: str) -> Dict[str, Any]:
+    return SERVICES.get(service_name, {})
+```
+
+### **3. OpenAPI Documentation**
+
+#### **Comprehensive API Documentation**
+```python
+app = FastAPI(
+    title="LabFusion Service Adapters",
+    description="Integration adapters for homelab services",
+    version="1.0.0",
+    docs_url="/docs",
+    redoc_url="/redoc"
+)
+```
+
+#### **Detailed Endpoint Documentation**
+```python
+@router.get(
+    "/events",
+    response_model=Dict[str, List[FrigateEvent]],
+    summary="Get Frigate events",
+    description="Retrieve recent events from Frigate camera system",
+    responses={
+        200: {"description": "Successfully retrieved events"},
+        503: {"description": "Frigate service unavailable"}
+    }
+)
+```
+
+## 📊 **Data Layer Best Practices**
+
+### **1. Pydantic Model Design**
+
+#### **Clean Model Structure**
+```python
+class ServiceStatus(BaseModel):
+    name: str
+    status: str
+    response_time: Optional[str] = None
+    last_check: Optional[datetime] = None
+    
+    class Config:
+        json_encoders = {
+            datetime: lambda v: v.isoformat()
+        }
+```
+
+#### **Proper Type Hints**
+```python
+from typing import List, Dict, Optional, Any
+from datetime import datetime
+
+class EventData(BaseModel):
+    event_type: str
+    service: str
+    timestamp: datetime
+    data: Dict[str, Any]
+```
+
+### **2. Configuration Management**
+
+#### **Environment-Based Configuration**
+```python
+# services/config.py
+import os
+
+SERVICES = {
+    "home_assistant": {
+        "name": "Home Assistant",
+        "url": os.getenv("HOME_ASSISTANT_URL", "http://homeassistant.local:8123"),
+        "token": os.getenv("HOME_ASSISTANT_TOKEN"),
+        "enabled": os.getenv("HOME_ASSISTANT_ENABLED", "true").lower() == "true"
+    }
+}
+```
+
+#### **Centralized Configuration**
+- All service configurations in one place
+- Environment variable support
+- Default values for development
+
+## 🚀 **Performance Optimizations**
+
+### **1. Async/Await Usage**
+```python
+async def fetch_ha_entities() -> List[HAEntity]:
+    async with httpx.AsyncClient() as client:
+        response = await client.get(f"{HA_URL}/api/states")
+        return response.json()
+```
+
+### **2. Connection Pooling**
+```python
+# services/redis_client.py
+class RedisClient:
+    def __init__(self, redis_url: str):
+        self.redis_url = redis_url
+        self.client = None
+    
+    async def connect(self):
+        self.client = await aioredis.from_url(self.redis_url)
+```
+
+### **3. Error Handling**
+```python
+async def safe_api_call(url: str, headers: Dict[str, str]) -> Optional[Dict]:
+    try:
+        async with httpx.AsyncClient() as client:
+            response = await client.get(url, headers=headers, timeout=5.0)
+            response.raise_for_status()
+            return response.json()
+    except httpx.TimeoutException:
+        logger.warning(f"Timeout calling {url}")
+        return None
+    except httpx.HTTPStatusError as e:
+        logger.error(f"HTTP error calling {url}: {e}")
+        return None
+```
+
+## 🧪 **Testing Strategy**
+
+### **1. Unit Testing**
+```python
+import pytest
+from unittest.mock import AsyncMock, patch
+from services.config import SERVICES
+
+@pytest.mark.asyncio
+async def test_get_services():
+    with patch('services.redis_client.get_redis_client') as mock_redis:
+        # Test implementation
+        pass
+```
+
+### **2. Integration Testing**
+```python
+@pytest.mark.asyncio
+async def test_home_assistant_integration():
+    # Test actual HA API calls
+    pass
+```
+
+### **3. Test Structure**
+```python
+# tests/test_home_assistant.py
+import pytest
+from fastapi.testclient import TestClient
+from main import app
+
+client = TestClient(app)
+
+def test_get_ha_entities():
+    response = client.get("/home-assistant/entities")
+    assert response.status_code == 200
+```
