+# API Error Handling & Resilience System
+
+This document describes the comprehensive error handling infrastructure added to the GridPilot website to handle API connectivity issues, request errors, and provide graceful degradation.
+
+## Overview
+
+The system provides:
+- **Enhanced error classification** with detailed error types
+- **Automatic retry logic** with exponential backoff
+- **Circuit breaker pattern** to prevent cascading failures
+- **Connection health monitoring** with real-time status
+- **User-friendly error messages** for production
+- **Developer-friendly debugging tools** for development
+- **Graceful degradation** with fallbacks and caching
+- **Offline mode detection**
+
+## Core Components
+
+### 1. Enhanced Error Classification (`ApiError`)
+
+**Location:** `lib/api/base/ApiError.ts`
+
+**Error Types:**
+- `NETWORK_ERROR` - Connection failed, CORS issues
+- `AUTH_ERROR` - 401/403 authentication issues
+- `VALIDATION_ERROR` - 400 bad request
+- `NOT_FOUND` - 404 resource not found
+- `SERVER_ERROR` - 500+ server issues
+- `RATE_LIMIT_ERROR` - 429 too many requests
+- `TIMEOUT_ERROR` - Request timeout
+- `CANCELED_ERROR` - Request aborted
+
+**Features:**
+- Automatic error type classification
+- User-friendly vs developer-friendly messages
+- Retry capability detection
+- Connectivity issue detection
+- Severity levels for logging
+
+### 2. Retry Handler & Circuit Breaker (`RetryHandler.ts`)
+
+**Location:** `lib/api/base/RetryHandler.ts`
+
+**Retry Logic:**
+- Exponential backoff with jitter
+- Configurable max retries (default: 3)
+- Configurable timeout (default: 30s)
+- Abort support for cancellation
+
+**Circuit Breaker:**
+- Tracks failures per endpoint
+- Opens after threshold (default: 5 failures)
+- Half-open state for recovery testing
+- Automatic reset after timeout
+
+### 3. Connection Monitor (`ApiConnectionMonitor.ts`)
+
+**Location:** `lib/api/base/ApiConnectionMonitor.ts`
+
+**Features:**
+- Real-time connection status tracking
+- Health check polling (every 30s)
+- Reliability percentage calculation
+- Event emitter for status changes
+- Request/response time tracking
+
+**Statuses:**
+- `connected` - Healthy API
+- `degraded` - Reduced reliability
+- `disconnected` - Unavailable
+- `checking` - Health check in progress
+
+### 4. Enhanced BaseApiClient (`BaseApiClient.ts`)
+
+**Location:** `lib/api/base/BaseApiClient.ts`
+
+**Enhancements:**
+- Automatic error classification
+- Retry logic integration

+
+**Usage:**
+```typescript
+const client = new BaseApiClient(
+  baseUrl,
+  errorReporter,
+  logger,
+  { timeout: 30000, retry: true }
+);
+
+// All methods now support retry and graceful degradation
+const data = await client.get('/api/endpoint');
+```
+
+### 5. Error UI Components
+
+**Location:** `components/errors/`
+
+**Components:**
+- `ErrorDisplay.tsx` - User-friendly error screen

+
+**Location:** `lib/api/base/GracefulDegradation.ts`
+
+**Features:**
+- Response caching with TTL
+- Fallback data support
+- Offline mode detection
+- Service wrapper for easy usage
+
+**Usage:**
+```typescript
+import { withGracefulDegradation, GracefulService } from './GracefulDegradation';
+
+// Direct usage
+const data = await withGracefulDegradation(
+  () => apiClient.getData(),
+  {
+    fallback: defaultData,
+    timeout: 5000,
+    useCache: true
+  }
+);
+
+// Service wrapper
+const userService = new GracefulService(
+  'user-data',
+  () => apiClient.getUser(),
+  defaultUser
+);
+
+const user = await userService.get();
+```
+
+### 7. Enhanced Error Reporter (`EnhancedErrorReporter.ts`)
+
+**Location:** `lib/infrastructure/EnhancedErrorReporter.ts`
+
+**Features:**
+- Environment-specific handling
+- User notification integration
+- Error buffering for batch reporting
+- Custom error handlers
+- External service integration (placeholder)
+
+## Integration in Application
+
+### Layout Integration
+
+```tsx
+// apps/website/app/layout.tsx
+
+import { NotificationIntegration } from '@/components/errors/NotificationIntegration';
+import { ApiErrorBoundary } from '@/components/errors/ApiErrorBoundary';
+import { ApiStatusToolbar } from '@/components/errors/ApiStatusToolbar';
+
+export default function RootLayout({ children }) {
+  return (
+    <html>
+      <body>
+        <NotificationProvider>
+          <NotificationIntegration />
+          <ApiErrorBoundary>
+            {/* Your app content */}
+            {children}
+            
+            {/* Development toolbar */}
+            {process.env.NODE_ENV === 'development' && (
+              <ApiStatusToolbar position="bottom-right" autoHide={true} />
+            )}
+          </ApiErrorBoundary>
+        </NotificationProvider>
+      </body>
+    </html>
+  );
+}
+```
+
+### Service Integration
+
+```typescript
+// lib/services/DriverService.ts
+
+import { BaseApiClient } from '@/lib/api/base/BaseApiClient';
+import { EnhancedErrorReporter } from '@/lib/infrastructure/EnhancedErrorReporter';
+import { ConsoleLogger } from '@/lib/infrastructure/ConsoleLogger';
+
+// Enhanced service with error handling
+export class DriverService {
+  private apiClient: BaseApiClient;
+  private errorReporter: EnhancedErrorReporter;
+
+  constructor() {
+    const logger = new ConsoleLogger();
+    this.errorReporter = new EnhancedErrorReporter(logger, {
+      showUserNotifications: true,
+      logToConsole: true,
+      reportToExternal: process.env.NODE_ENV === 'production',
+    });
+
+    this.apiClient = new BaseApiClient(
+      getWebsiteApiBaseUrl(),
+      this.errorReporter,
+      logger,
+      { timeout: 30000, retry: true }
+    );
+  }
+
+  async getDriverProfile(driverId: string): Promise<DriverProfileViewModel | null> {
+    try {
+      const dto = await this.apiClient.getDriverProfile(driverId);
+      return new DriverProfileViewModel(dto);
+    } catch (error) {
+      // Error already handled by BaseApiClient
+      // Return null for graceful degradation
+      return null;
+    }
+  }
+}
+```
+
+## Development Tools
+
+### DevToolbar Integration
+
+The enhanced DevToolbar includes:
+- Real-time API status indicator
+- Reliability percentage
+- Circuit breaker status
+- Health check button
+- Stats reset
+- Test error trigger
+
+### ApiStatusToolbar
+
+A floating toolbar that shows:
+- Current connection status
+- Request statistics
+- Circuit breaker states
+- Quick actions for testing
+
+## Error Handling Patterns
+
+### 1. Automatic Retry
+```typescript
+// Automatically retries failed requests
+const data = await client.get('/api/data');
+```
+
+### 2. Graceful Fallback
+```typescript
+const data = await withGracefulDegradation(
+  () => client.get('/api/data'),
+  { fallback: defaultData }
+);
+```
+
+### 3. Error Boundary
+```typescript
+<ApiErrorBoundary>
+  <MyComponent />
+</ApiErrorBoundary>
+```
+
+### 4. Manual Error Handling
+```typescript
+try {
+  const data = await client.get('/api/data');
+} catch (error) {
+  if (isApiError(error)) {
+    if (error.isRetryable()) {
+      // Show retry button
+    }
+    if (error.isConnectivityIssue()) {
+      // Show connection error
+    }
+  }
+}
+```
+
+## Environment-Specific Behavior
+
+### Development
+- Detailed error messages with stack traces
+- Developer error panel with full context
+- API status toolbar always visible
+- Console logging with full details
+- Test error triggers
+
+### Production
+- User-friendly error messages
+- Modal notifications for critical errors
+- Toast notifications for warnings
+- No sensitive data in error messages
+- Automatic error reporting to external services
+
+## Monitoring & Debugging
+
+### Connection Health
+```typescript
+import { connectionMonitor } from '@/lib/api/base/ApiConnectionMonitor';
+
+// Get current status
+const status = connectionMonitor.getStatus();
+
+// Get detailed health
+const health = connectionMonitor.getHealth();
+
+// Run manual health check
+const result = await connectionMonitor.performHealthCheck();
+```
+
+### Circuit Breaker Status
+```typescript
+import { CircuitBreakerRegistry } from '@/lib/api/base/RetryHandler';
+
+const registry = CircuitBreakerRegistry.getInstance();
+const status = registry.getStatus();
+```
+
+### Error Buffer
+```typescript
+import { getGlobalErrorReporter } from '@/lib/infrastructure/EnhancedErrorReporter';
+
+const reporter = getGlobalErrorReporter();
+const errors = reporter.getBufferedErrors();
+reporter.flush(); // Send batch
+```
+
+## Best Practices
+
+1. **Always use BaseApiClient** for API calls
+2. **Wrap critical components** with ApiErrorBoundary
+3. **Provide fallbacks** for graceful degradation
+4. **Use error classification** for specific handling
+5. **Monitor connection status** for user feedback
+6. **Test error scenarios** in development
+7. **Log appropriately** based on severity
+8. **Use caching** for frequently accessed data
+
+## Troubleshooting
+
+### API Always Shows "Disconnected"
+- Check API_BASE_URL environment variable
+- Verify CORS configuration on API server
+- Check browser console for network errors
+- Use DevToolbar health check
+
+### Requests Not Retrying
+- Verify retry option is enabled in BaseApiClient
+- Check error type is retryable
+- Review circuit breaker status
+
+### Notifications Not Showing
+- Ensure NotificationProvider wraps your app
+- Check NotificationIntegration is mounted
+- Verify error severity levels
+
+### Circuit Breaker Stays Open
+- Check API server health
+- Reset circuit breakers via DevToolbar
+- Review error logs for root cause
+
+## Future Enhancements
+
+- External error reporting (Sentry, LogRocket)
+- Persistent cache storage (IndexedDB)
+- Offline queue for failed requests
+- Performance metrics dashboard
+- A/B testing for error recovery strategies
