Push notifications huruhusu programu kuwajulisha watumiaji hata wakati programu haijafunguliwa — kwa ujumbe, updates, na ushirikiano. Katika React Native, zinahusisha huduma za platform (APNs kwa iOS, FCM kwa Android), permissions, device tokens, na kushughulikia matukio ya notification.
Jinsi push notifications zinavyofanya kazi (mtiririko)
1. The app requests notification PERMISSION from the user (especially iOS — opt-in)
2. The device registers and gets a unique push TOKEN (identifies this device/app install)
3. The app sends the token to YOUR SERVER (stores it to target this device)
4. Your server sends a notification → via the platform service:
APNs (Apple Push Notification service) for iOS, FCM (Firebase Cloud Messaging) for Android
5. The platform delivers it to the device → the app shows/handles it
→ Notifications work even when the app is closed (the OS handles delivery).
