Kepiye cara push notifications ngurus ing React Native?

Question

Accepted Answer

**Push notifications** ngidini aplikasi menerangake pengguna sanajan aplikasi ora mbukak — kanggo pesen, update, lan engagement. Ing React Native, dheweke melu layanan platform (APNs kanggo iOS, FCM kanggo Android), ijin, device token, lan nangani acara notifikasi.

## Kepiye push notifications ngurus (aluranse)

```text
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).
```

## Nggumekake ing React Native

```text
→ LIBRARIES handle the complexity:
  - Expo Notifications (managed, simpler) — for Expo apps
  - @react-native-firebase/messaging (FCM) — common for bare/cross-platform
  - Notifee — rich local/displayed notifications
→ Request permission, get the token, send it to your backend, handle received notifications
```

## Nangani notifikasi

```text
✓ FOREGROUND — app open: handle the notification in-app (show a banner, update data)
✓ BACKGROUND / closed — the OS shows it; tapping it OPENS the app (often to a specific
  screen — DEEP LINKING from the notification)
✓ Types: REMOTE (from a server, push) vs LOCAL (scheduled by the app itself)
✓ Handle the token lifecycle (refresh), permissions, and notification taps (navigation)
```

## Apa arti penting

Paham kepiye push notifications ngurus penting amarga **notifikasi minangka fitur umum lan penting** kanggo engagement pengguna lan komunikasi, mula penting dadi katrangan praktikal kanggo aplikasi sing butuh.

Push notifications (menerangake pengguna sanajan aplikasi ora mbukak — kanggo pesen, update, pengingat, lan engagement) minangka fitur sing dibutuhake kanthi luwes, lan paham kepiye cara karep ing React Native penting.

Paham **alure** — njaluk **ijin** (khususé opt-in iOS), entuk **device token** unik, ngirim menyang **server sampeyan** (kanggo target device), lan server ngirim notifikasi **liwat layanan platform** (APNs kanggo iOS, FCM kanggo Android) sing ngirim menyang device sanajan aplikasi ditutup — njlajahi arsitektur, sing melu aplikasi sampeyan, backend, lan layanan push platform bekerja sabar.

Paham yen **perpustakaan ngurus pajedhèn** (Expo Notifications kanggo aplikasi sing dikelola, React Native Firebase kanggo FCM, Notifee kanggo notifikasi sugih) cerminan kasunyatan praktikal yen sampeyan nggunakake perpustakaan tinimbang nggumekake rincian level-bawah.

Paham **nangani notifikasi** — prabéda antarane foreground (aplikasi mbukak, nangani in-app), background/ditutup (OS nuduhake, ngletak mbukak aplikasi, asring nganggo **deep linking** menyang layar khusus), lan notifikasi remote vs lokal, plus ngatur siklus hidup token lan ngetok notifikasi (navigasi) — perlu kanggo nggumekake notifikasi kanthi bener.

Notifikasi penting kanggo engagement lan komunikasi (prasyarat produk umum), lan nggumekakéne melu layanan platform-khusus lan sawetara bagéan sing obah.

Dheweke push notifications minangka fitur umum lan barga kanggo engagement lan komunikasi, lan dheweke paham alure (ijin, token, layanan platform), perpustakaan, lan nangani notifikasi (foreground/background, deep linking) perlu kanggo nggumekakéne, paham push notifications ing React Native penting, praktis-kabar pengetahuan — penting kanggo kebutuhan umum menerangake lan melu pengguna, melu layanan platform-khusus lan alur multi-bagéan sing paham njlajahi, kabehan berguna kanggo aplikasi nyata akeh.
