Push-meldinger lar apper varsle brukere selv når appen ikke er åpen — for meldinger, oppdateringer og brukerengasjement. I React Native involverer de plattformtjenester (APNs for iOS, FCM for Android), tillatelser, enhetsnøkler og håndtering av meldings-hendelser.
Hvordan push-meldinger fungerer (flyten)
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).
