Push Notification Setup

Implement push notifications across mobile and web platforms.

Firebase Cloud Messaging (React Native)

import messaging from '@react-native-firebase/messaging';

// Request permission
async function requestPermission() {
  const status = await messaging().requestPermission();
  if (status === messaging.AuthorizationStatus.AUTHORIZED) {
    const token = await messaging().getToken();
    await sendTokenToServer(token);
  }
}

// Handle foreground messages
messaging().onMessage(async message => {
  console.log('Foreground message:', message);
  showLocalNotification(message);
});

// Handle background/quit messages
messaging().setBackgroundMessageHandler(async message => {
  console.log('Background message:', message);
});

// Handle token refresh
messaging().onTokenRefresh(token => {
  sendTokenToServer(token);
});

iOS Native (Swift)

import UserNotifications

func requestAuthorization() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
        if granted {
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    sendTokenToServer(token)
}
