# Background notifications — handoff
|
|
|
|
## Summary
|
|
|
|
Paarrot keeps users notified of Matrix activity when the app is in the background: desktop tray/favicon badges, system notifications (Electron/Tauri/Android), and Android **UnifiedPush** for reliable mobile push without Google FCM dependency.
|
|
|
|
## User-facing behavior
|
|
|
|
- Unread counts update favicon (Paarrot / unread / highlight variants)
|
|
- System notifications for mentions/DMs per notification settings
|
|
- Android: requires UnifiedPush distributor (e.g. ntfy); user prompted if missing
|
|
- Foreground/background state affects sync strategy
|
|
|
|
## Architecture
|
|
|
|
```
|
|
ClientNonUIFeatures.tsx
|
|
→ FaviconUpdater (roomToUnread atom)
|
|
→ notification listeners (tauri.ts sendNotification)
|
|
→ initPaarrotAPI + background sync lifecycle
|
|
backgroundSync.ts
|
|
→ UnifiedPush registration, pusher setup
|
|
→ setAppForegroundState / startBackgroundSync / stopBackgroundSync
|
|
tauri.ts / electron main
|
|
→ OS notification APIs, Android small icon ic_stat_paarrot
|
|
```
|
|
|
|

## Data model
|
|
|
|
| Key | Storage | Purpose |
|
|
|-----|---------|---------|
|
|
| `paarrot.unifiedpush.*` | localStorage prefix | UP endpoint state |
|
|
| `com.paarrot.app.android` | Pusher app id base | Android pushers |
|
|
| Matrix pusher | Homeserver | HTTP push gateway |
|
|
|
|
## Dependencies
|
|
|
|
- UnifiedPush distributor app on Android
|
|
- Notification permission (browser/OS)
|
|
- Homeserver pusher support
|
|
- `matrix-js-sdk` sync
|
|
|
|
## Integration points
|
|
|
|
- **Settings → Notifications**: rules + system permission
|
|
- **DirectTab / sidebar**: custom Paarrot SVG favicon states
|
|
- **Deep links**: notification tap → `setupNotificationTapListener`
|
|
|
|
## Testing
|
|
|
|
### Manual
|
|
|
|
1. Desktop: background app; send mention; verify system notification.
|
|
2. Verify favicon switches unread/highlight with counts.
|
|
3. Android: install ntfy; verify push when app killed.
|
|
4. Toggle notification settings; verify respect mute rules.
|
|
|
|
### Automated
|
|
|
|
- None
|
|
|
|
## Known issues & gotchas
|
|
|
|
- UnifiedPush user education string in `backgroundSync.ts` if no distributor
|
|
- Multiple runtimes: `isTauri`, `isElectron`, `isCapacitorNative` branch logic
|
|
- Pusher registration races on fast login/logout
|
|
- Android small icon: `ic_stat_paarrot` must exist in Android resources
|
|
- Background wake (`MatrixSyncService`) must filter by push rules / unread_notifications; a push for one room used to notify for every new message in the sync batch
|
|
|
|
## Future work
|
|
|
|
- iOS push strategy
|
|
- Notification action buttons (reply, mark read)
|
|
- Per-room notification channels on Android

## Add your extra things here
|
|
|
|
- Constants: `PUSHER_APP_ID_BASE`, `PUSHER_STORAGE_PREFIX` in `backgroundSync.ts`
|
|
- Logo assets: `paarrot.svg`, `paarrot-unread.svg`, `paarrot-highlight.svg` in `public/res/svg/`
|
|
- Android notify filter: mute / mentions / default-room behavior lives in `MatrixSyncService.resolveRoomNotifyMode`
