Initialize WebSocket Server + +Update your Express server setup to initialize WebSocket support: + +```typescript +import express from 'express'; +import { createServer } from 'http'; +import { webSocketService } from './services/websocket.js'; + +const app = express(); +const httpServer = createServer(app); + +// Initialize WebSocket +const io = webSocketService.initialize(httpServer); + +// Start server +httpServer.listen(3001, () => { + console.log('Server running on port 3001'); +}); +``` + +### 2.

Authentication Middleware + +Ensure auth middleware is configured for push routes. The middleware should attach `user.id` and `user.tenantId` to the request: + +```typescript +// middleware/auth.ts +export const authMiddleware = (req: Request, res: Response, next: NextFunction) => { + const token = req.headers.authorization?.split(' ')[1]; + + // Validate JWT and attach user to request + // (req as any).user = { id: userId, tenantId: tenantId }; + + next(); +}; +``` + +## Frontend Integration + +### 1.

Add Notification Components + +Import and use the notification components in your app: + +```typescript +import { PushNotificationManager } from '@/components/PushSubscription'; +import { NotificationCenter } from '@/components/NotificationCenter'; +import { NotificationPreferences } from '@/components/NotificationPreferences'; + +export function App() { + return ( +
+ {/* Notification Manager - handles subscription */} + + + {/* Notification Center - displays history */} + + + {/* Preferences - user settings */} + +
+ ); +} +``` + +### 3. Setup WebSocket Provider + +Wrap your app with the WebSocket provider for real-time notifications: + +```typescript +import { WebSocketNotificationProvider } from '@/hooks/useWebSocketNotifications'; + +export function RootLayout({ children }: { children: React.ReactNode }) { + return ( + + {children} + + ); +} +``` + +## Service Worker Setup + +The service worker is automatically registered and includes push event handling.
