Purpose & Overview

Comprehensive guide for configuring cross-platform push notifications (Expo Push API, Firebase Cloud Messaging FCM, Apple APNs, Web Push API), iOS Live Activities / ActivityKit, background payload handlers, deep-linking routing, and push token lifecycle management.

Key Capabilities

• Expo & FCM Push: Sending batched push notifications with rich media, actions, and custom data payloads.
• iOS Live Activities: Real-time status updates on iOS Dynamic Island and Lock Screen.
• Deep Linking: Routing push notification taps directly to targeted screens within Expo Router / React Native.

import * as Notifications from 'expo-notifications';

export async function registerForPushNotificationsAsync() {
  const { status: existingStatus } = await Notifications.getPermissionsAsync();
  let finalStatus = existingStatus;
  if (existingStatus !== 'granted') {
    const { status } = await Notifications.requestPermissionsAsync();
    finalStatus = status;
  }
  if (finalStatus !== 'granted') return null;
  const token = (await Notifications.getExpoPushTokenAsync()).data;
  return token;
}

Implementation Checklist

• Configure Apple Developer Account (APNs Key) and Google Firebase (FCM Service Account).
• Request push notification permissions explicitly from the user after they understand the value proposition.
• Save the device's Push Token to the database, associated with the user's ID.
• Handle token refresh events when the user uninstalls/reinstalls the app or changes devices.
• Set up background event handlers to process incoming messages when the app is killed.
