Push notifications laten apps gebruikers notificeren, zelfs wanneer de app niet open is — voor berichten, updates en engagement. In React Native zijn ze afhankelijk van platformservices (APNs voor iOS, FCM voor Android), permissions, device tokens en het afhandelen van notification events.
Hoe push notifications werken (de flow)
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).
