Push notifikacije omogućavaju aplikacijama obavijest korisnika čak i kada aplikacija nije otvorena — za poruke, ažuriranja i angažman korisnika. U React Nativeu, uključuju usluge platforme (APNs za iOS, FCM za Android), dozvole, tokene uređaja i rukovanje događajima notifikacija.
Kako funkcioniraju push notifikacije (tok)
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).
