# Push Notifications Implementation Summary
|
||||
|
||||
**Status**: ✅ **COMPLETED** (Backend + Frontend Integration Ready)
|
||||
**Date**: October 8, 2025
|
||||
**Implementation Type**: Web Push (VAPID) - No Firebase/OneSignal dependency
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
We successfully implemented a **streamlined, fully local Web Push notification system** for ParentFlow using the Web Push Protocol with VAPID keys. This allows browser-based push notifications without relying on third-party services like Firebase or OneSignal.
|
||||
|
||||
---
|
||||
|
||||
## 📦 Backend Implementation
|
||||
|
||||
### 1. Database Schema ✅
|
||||
|
||||
**Table**: `push_subscriptions` (Already exists in production)
|
||||
|
||||
```sql
|
||||
CREATE TABLE push_subscriptions (
|
||||
id uuid PRIMARY KEY DEFAULT uuid_generate_v4(),
|
||||
user_id varchar(20) NOT NULL,
|
||||
endpoint text NOT NULL UNIQUE,
|
||||
p256dh text NOT NULL,
|
||||
auth text NOT NULL,
|
||||
user_agent text,
|
||||
device_type varchar(20),
|
||||
browser varchar(50),
|
||||
is_active boolean DEFAULT true,
|
||||
last_error text,
|
||||
failed_attempts integer DEFAULT 0,
|
||||
last_success_at timestamp,
|
||||
created_at timestamp DEFAULT now(),
|
||||
updated_at timestamp DEFAULT now()
|
||||
);
|
||||
```
|
||||
|
||||
**Indexes**:
|
||||
- `idx_push_subs_user_id` on `user_id`
|
||||
- `idx_push_subs_active` on `is_active` (WHERE is_active = true)
|
||||
- `unique_endpoint` on `endpoint`
|
||||
|
||||
### 2. TypeORM Entity ✅
|
||||
|
||||
**File**: `src/database/entities/push-subscription.entity.ts`
|
||||
|
||||
Features:
|
||||
- Relationship with User entity (CASCADE delete)
|
||||
- Tracks device type, browser, and subscription health
|
||||
- Automatic timestamps (created_at, updated_at)
|
||||
|
||||
### 3. Push Service ✅
|
||||
|
||||
**File**: `src/modules/push/push.service.ts`
|
||||
|
||||
**Key Features**:
|
||||
- VAPID configuration from environment variables
|
||||
- Subscribe/unsubscribe management
|
||||
- Send push notifications to individual users or groups
|
||||
- Automatic error handling (404/410 = deactivate, retries for 5xx)
|
||||
- User agent parsing for device/browser detection
|
||||
- Statistics and cleanup utilities
|
||||
|
||||
**Main Methods**:
|
||||
```typescript
|
||||
- getPublicVapidKey(): string
|
||||
- subscribe(userId, subscriptionData, userAgent): PushSubscription
|
||||
- unsubscribe(userId, endpoint): void
|
||||
- sendToUser(userId, payload): {sent, failed}
|
||||
- sendToUsers(userIds[], payload): {sent, failed}
|
||||
- sendTestNotification(userId): void
|
||||
- cleanupInactiveSubscriptions(daysOld): number
|
||||
- getStatistics(userId?): Statistics
|
||||
```
|
||||
|
||||
### 4. Push Controller ✅
|
||||
|
||||
**File**: `src/modules/push/push.controller.ts`
|
||||
|
||||
**REST API Endpoints**:
|
||||
|
||||
| Method | Endpoint | Description |
|
||||
|--------|----------|-------------|
|
||||
| GET | `/api/v1/push/vapid-public-key` | Get VAPID public key for frontend |
|
||||
| POST | `/api/v1/push/subscriptions` | Subscribe to push notifications |
|
||||
| GET | `/api/v1/push/subscriptions` | Get user's active subscriptions |
|
||||
| DELETE | `/api/v1/push/subscriptions?endpoint=...` | Unsubscribe from push |
|
||||
| POST | `/api/v1/push/test` | Send test notification |
|
||||
| GET | `/api/v1/push/statistics` | Get push statistics |
|
||||
|
||||
**Authentication**: All endpoints require JWT authentication (`JwtAuthGuard`)
|
||||
|
||||
### 5. Push Module ✅
|
||||
|
||||
**File**: `src/modules/push/push.module.ts`
|
||||
|
||||
Wired into main `AppModule` and exports `PushService` for use by other modules.
|
||||
|
||||
### 6. Notifications Integration ✅
|
||||
|
||||
**Updated**: `src/modules/notifications/notifications.service.ts`
|
||||
|
||||
**Features**:
|
||||
- Automatic push notification when creating notifications
|
||||
- Intelligent URL routing based on notification type
|
||||
- Smart notifications (feeding, sleep, diaper reminders) now trigger push
|
||||
- Medication reminders trigger push
|
||||
- Anomaly detection triggers push
|
||||
|
||||
**Integration Flow**:
|
||||
```
|
||||
createNotification()
|
||||
→ Save to DB
|
||||
→ sendPushNotification()
|
||||
→ PushService.sendToUser()
|
||||
→ markAsSent/markAsFailed
|
||||
```
|
||||
|
||||
### 7. Environment Configuration ✅
|
||||
|
||||
**File**: `maternal-app-backend/.env`
|
||||
|
||||
```ini
|
||||
# Push Notifications (Web Push - VAPID)
|
||||
PUSH_NOTIFICATIONS_ENABLED=true
|
||||
VAPID_PUBLIC_KEY=BErlB-L0pDfv1q3W0SHs3ZXqyFi869OScpt5wJ2aNu2KKbLxLj4a-YO6SyuAamjRG_cqY65yt2agyXdMdy2wEXI
|
||||
VAPID_PRIVATE_KEY=Rg47clL1z4wSpsBTx4yIOIHHX9qh1W5TyBZwBfPIesk

VAPID_SUBJECT=mailto:hello@parentflow.com
|
||||
PUSH_DEFAULT_TTL=86400
|
||||
PUSH_BATCH_SIZE=100
|
||||
```
|
||||
|
||||
**Security**: Keep `VAPID_PRIVATE_KEY` secret. Never expose in logs or client-side code.

|
||||
```
|
||||
|
||||
2. **Subscribe** (requires auth token):
|
||||
```bash
|
||||
curl -X POST http://localhost:3020/api/v1/push/subscriptions \
|
||||
-H "Authorization: Bearer YOUR_JWT_TOKEN" \

"auth": "..."
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
3. **Send Test Notification**:
|
||||
```bash
|
||||
curl -X POST http://localhost:3020/api/v1/push/test \
|
||||

|
||||
- Grant permission when prompted
|
||||
- Wait for confirmation
|
||||
|
||||
4. **Test Notification**:

|
||||
- ✅ Chrome (Desktop & Mobile)
|
||||
- ✅ Firefox (Desktop & Mobile)
|
||||
- ✅ Edge (Desktop)
|
||||
- ✅ Safari (iOS 16.4+ PWA only - must be installed to home screen)
|
||||
|
||||
---
|
||||
|
||||
## 📊 Notification Flow
|
||||
|
||||
```
|
||||
1. User Action (e.g., feeding activity)
|
||||
↓
|
||||
2. NotificationsService detects pattern
|
||||
↓
|
||||
3. createNotification() called
|
||||
↓
|
||||
4. Notification saved to DB
|
||||
↓
|
||||
5. sendPushNotification() triggered

|
||||
|
||||
## 🔒 Security Considerations
|
||||
|
||||
### VAPID Keys
|
||||
- ✅ Private key stored in `.env` (never committed to git)
|
||||
- ✅ Public key safe to expose to frontend
|
||||
- ✅ Subject configured as `mailto:` contact email
|
||||
|
||||
### Authentication
|
||||
- ✅ All push endpoints require JWT authentication
|
||||
- ✅ Users can only manage their own subscriptions
|
||||
- ✅ Endpoint validation prevents injection attacks
|
||||
|
||||
### Data Privacy
|
||||
- ✅ Subscription endpoints hashed in logs
|
||||
- ✅ User agent data stored for analytics only
|
||||
- ✅ Inactive subscriptions auto-cleaned after 90 days
|
||||
- ✅ Cascade delete when user is deleted
|
||||
|
||||
### Rate Limiting
|
||||
- ⚠️ **TODO**: Add rate limiting to push endpoints
|
||||
- Recommended: 10 requests/minute per user for subscribe/unsubscribe
|
||||
- Recommended: 100 notifications/day per user
|
||||
|
||||
---
|
||||
|
||||
## 📈 Monitoring & Maintenance
|
||||
|
||||
### Database Cleanup
|
||||
|
||||
Run periodic cleanup (recommended: daily cron job):
|
||||
```sql
|
||||
-- Delete inactive subscriptions older than 90 days
|
||||
DELETE FROM push_subscriptions
|
||||
WHERE is_active = false
|
||||
AND updated_at < NOW() - INTERVAL '90 days';
|
||||
```
|
||||
|
||||
Or use the service method:
|
||||
```typescript
|
||||
await pushService.cleanupInactiveSubscriptions(90);
|
||||
```
|
||||
|
||||
### Statistics Monitoring
|
||||
|
||||
```typescript
|
||||
const stats = await pushService.getStatistics();
|
||||
// Returns:
|
||||
// {
|
||||
// totalSubscriptions: 150,
|
||||
// activeSubscriptions: 142,
|
||||
// inactiveSubscriptions: 8,
|
||||
// byBrowser: { chrome: 100, firefox: 30, safari: 12 },
|
||||
// byDeviceType: { mobile: 90, desktop: 50, tablet: 10 }
|
||||
// }
|
||||
```
|
||||
|
||||
### Error Monitoring
|
||||
|
||||
Check push subscription errors:
|
||||
```sql
|
||||
SELECT user_id, endpoint, last_error, failed_attempts
|
||||
FROM push_subscriptions
|
||||
WHERE is_active = false
|
||||
AND last_error IS NOT NULL
|
||||
ORDER BY updated_at DESC
|
||||
LIMIT 20;
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🚀 Deployment Checklist

|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎨 Customization Guide
|
||||
|
||||
### Notification Appearance
|
||||
|
||||
Edit in `maternal-web/public/push-sw.js`:
|
||||
```javascript
|
||||
const options = {
|
||||
body: data.body,
|
||||
icon: '/icons/icon-192x192.png', // Change app icon
|
||||
badge: '/icons/icon-72x72.png', // Change badge icon
|
||||
vibrate: [200, 100, 200], // Customize vibration pattern
|
||||
tag: data.tag || 'default',
|
||||
data: data.data || {},
|
||||
requireInteraction: false, // Set true for persistent notifications
|
||||
};
|
||||
```
|
||||
|
||||
### Notification URLs
|
||||
|
||||
Edit URL routing in `notifications.service.ts`:
|
||||
```typescript
|
||||
private getNotificationUrl(notification: Notification): string {
|
||||
switch (notification.type) {
|
||||
case NotificationType.FEEDING_REMINDER:
|
||||
return `/children/${notification.childId}/activities`;
|
||||
// Add custom routes here
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Notification Triggers
|
||||
|
||||
Add custom notification triggers in `notifications.service.ts`:
|
||||
```typescript
|
||||
async createCustomNotification(userId: string, childId: string) {
|
||||
await this.createNotification(
|
||||
userId,
|
||||
NotificationType.CUSTOM,
|
||||
'Custom Title',
|
||||
'Custom Message',
|
||||
{
|
||||
childId,
|
||||
priority: NotificationPriority.HIGH,
|
||||
metadata: { customData: 'value' }
|
||||
}
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Issue**: "Push notifications not supported"
|
||||
**Solution**: Ensure HTTPS is enabled. Service Workers require secure context.
|
||||
|
||||
**Issue**: "Permission denied"
|
||||
**Solution**: User must manually reset permissions in browser settings.
|
||||
|
||||
**Issue**: "Subscription failed"
|
||||
**Solution**: Check VAPID public key is correctly fetched from backend.
|
||||
|
||||
**Issue**: "Notifications not appearing"
|
||||
**Solution**: Check browser notification settings, ensure service worker is registered.
|
||||
|
||||
**Issue**: "Push fails with 404/410"
|
||||
**Solution**: Subscription is invalid/expired. System auto-deactivates these.
|
||||
|
||||
**Issue**: "iOS not receiving notifications"
|
||||
**Solution**: On iOS, app must be installed as PWA (Add to Home Screen).
|
||||
|
||||
### Debug Logs
|
||||
|
||||
**Browser Console**:
|
||||
```javascript
|
||||
// Check service worker registration
|
||||
navigator.serviceWorker.getRegistrations().then(console.log);
|
||||
|
||||
// Check current subscription

# Push Notifications Persistence Implementation
|
||||
|
||||
**Status**: ✅ **COMPLETED**
|
||||
**Date**: October 8, 2025
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
This document summarizes the implementation of **persistent notification preferences** for the ParentFlow push notifications system. Users' notification settings are now stored in the database and respected across sessions and devices.
|
||||
|
||||
---
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### 1. Enhanced User Entity ✅
|
||||
|
||||
**File**: `src/database/entities/user.entity.ts`
|
||||
|
||||
Updated the `preferences` JSONB column to include detailed notification settings:
|
||||
|
||||
```typescript
|
||||
preferences?: {
|
||||
notifications?: {
|
||||
pushEnabled?: boolean; // Master toggle for push notifications
|
||||
emailEnabled?: boolean; // Email notifications toggle
|
||||
feedingReminders?: boolean; // Feeding reminder notifications
|
||||
sleepReminders?: boolean; // Sleep reminder notifications
|
||||
diaperReminders?: boolean; // Diaper change notifications
|
||||
medicationReminders?: boolean; // Medication reminders
|
||||
milestoneAlerts?: boolean; // Milestone achievement alerts
|
||||
patternAnomalies?: boolean; // Pattern anomaly warnings
|
||||
};
|
||||
emailUpdates?: boolean;
|
||||
darkMode?: boolean;
|
||||
measurementUnit?: 'metric' | 'imperial';
|
||||
timeFormat?: '12h' | '24h';
|
||||
}
|
||||
```
|
||||
|
||||
**Database**: Uses existing `users.preferences` JSONB column - no migration needed!
|
||||
|
||||
---
|
||||
|
||||
### 2. User Preferences Service ✅
|
||||
|
||||
**File**: `src/modules/users/user-preferences.service.ts`
|
||||
|
||||
Complete service for managing user preferences with the following methods:
|
||||
|
||||
#### Core Methods
|
||||
- `getUserPreferences(userId)` - Get all preferences with defaults
|
||||
- `updateUserPreferences(userId, preferences)` - Update any preference
|
||||
- `updateNotificationPreferences(userId, notificationPreferences)` - Update notification settings only
|
||||
|
||||
#### Push Notification Helpers
|
||||
- `enablePushNotifications(userId)` - Enable push notifications
|
||||
- `disablePushNotifications(userId)` - Disable push notifications
|
||||
- `isPushNotificationsEnabled(userId)` - Check if push is enabled
|
||||
- `isNotificationTypeEnabled(userId, type)` - Check specific notification type
|
||||
|
||||
#### Utility Methods
|
||||
- `getNotificationPreferencesSummary(userId)` - Get summary of enabled/disabled types
|
||||
- `resetToDefaults(userId)` - Reset all preferences to defaults
|
||||
|
||||
**Default Values**: All notification types are **enabled by default** to ensure users receive important reminders.
|
||||
|
||||
---
|
||||
|
||||
### 3. Preferences Controller ✅
|
||||
|
||||
**File**: `src/modules/users/user-preferences.controller.ts`
|
||||
|
||||
REST API endpoints for managing preferences:
|
||||
|
||||
| Method | Endpoint | Description |
|
||||
|--------|----------|-------------|
|
||||
| GET | `/api/v1/preferences` | Get all user preferences |
|
||||
| PUT | `/api/v1/preferences` | Update all preferences |
|
||||
| PUT | `/api/v1/preferences/notifications` | Update notification preferences only |
|
||||
| POST | `/api/v1/preferences/notifications/push/enable` | Enable push notifications |
|
||||
| POST | `/api/v1/preferences/notifications/push/disable` | Disable push notifications |
|
||||
| GET | `/api/v1/preferences/notifications/summary` | Get notification settings summary |
|
||||
| POST | `/api/v1/preferences/reset` | Reset all preferences to defaults |
|
||||
|
||||
**Authentication**: All endpoints require JWT authentication
|
||||
|
||||
---
|
||||
|
||||
### 4. Users Module ✅
|
||||
|
||||
**File**: `src/modules/users/users.module.ts`
|
||||
|
||||
New NestJS module that:
|
||||
- Imports User entity from TypeORM
|
||||
- Provides UserPreferencesService and UserPreferencesController
|
||||
- Exports UserPreferencesService for use by other modules
|
||||
- Integrated into main AppModule
|
||||
|
||||
---
|
||||
|
||||
### 5. Updated Push Service ✅
|
||||
|
||||
**File**: `src/modules/push/push.service.ts`
|
||||
|
||||
Enhanced `sendToUser()` method to:
|
||||
1. Check if user has push notifications enabled via `UserPreferencesService`
|
||||
2. Skip sending if push is disabled at user level
|
||||
3. Log when notifications are skipped due to preferences
|
||||
|
||||
```typescript
|
||||
async sendToUser(userId: string, payload: PushNotificationPayload) {
|
||||
// Check if user has push notifications enabled
|
||||
const isPushEnabled = await this.userPreferencesService.isPushNotificationsEnabled(userId);
|
||||
|
||||
if (!isPushEnabled) {
|
||||
this.logger.debug(`Push notifications disabled for user ${userId}, skipping`);
|
||||
return { sent: 0, failed: 0 };
|
||||
}
|
||||
|
||||
// Continue with sending...
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 6. Updated DTOs ✅
|
||||
|
||||
**File**: `src/modules/auth/dto/update-profile.dto.ts`
|
||||
|
||||
Created new DTOs to match the enhanced preference structure:
|
||||
|
||||
**NotificationPreferencesDto**:
|
||||
- Validates all notification preference fields
|
||||
- All fields optional with `@IsBoolean()` validation
|
||||
|
||||
**UserPreferencesDto**:
|
||||
- Updated to use `NotificationPreferencesDto` instead of simple boolean
|
||||
- Maintains backward compatibility
|
||||
|
||||
**UpdateProfileDto**:
|
||||
- Uses updated `UserPreferencesDto`
|
||||
- Allows updating preferences via profile endpoint
|
||||
|
||||
---
|
||||
|
||||
### 7. Frontend Integration ✅
|
||||
|
||||
**File**: `maternal-web/components/PushNotificationToggle.tsx`
|
||||
|
||||
Enhanced component to:
|
||||
1. Save preference to backend when toggling push notifications
|
||||
2. Call new `PUT /api/v1/preferences/notifications` endpoint
|
||||
3. Handle errors gracefully (subscription works even if preference save fails)
|
||||
|
||||
```typescript
|
||||
const savePreference = async (authToken: string, enabled: boolean) => {
|
||||
const response = await fetch(`${apiUrl}/api/v1/preferences/notifications`, {
|
||||
method: 'PUT',
|
||||
headers: {
|
||||
'Content-Type': 'application/json',
|
||||
'Authorization': `Bearer ${authToken}`,
|
||||
},
|
||||
body: JSON.stringify({
|
||||
pushEnabled: enabled,
|
||||
}),
|
||||
});
|
||||
};
|
||||
```
|
||||
|
||||

|
||||

---
|
||||
|
||||
## Database Storage
|
||||
|
||||
### Schema
|
||||
|
||||
The preferences are stored in the existing `users.preferences` JSONB column:
|
||||
|
||||
```sql
|
||||
-- Example data
|
||||
UPDATE users
|
||||
SET preferences = '{
|
||||
"notifications": {
|
||||
"pushEnabled": true,
|
||||
"emailEnabled": true,
|
||||
"feedingReminders": true,
|
||||
"sleepReminders": true,
|
||||
"diaperReminders": true,
|
||||
"medicationReminders": true,
|
||||
"milestoneAlerts": true,
|
||||
"patternAnomalies": true
|
||||
},
|
||||
"emailUpdates": true,
|
||||
"darkMode": false,
|
||||
"measurementUnit": "metric",
|
||||
"timeFormat": "12h"
|
||||
}'
|
||||
WHERE id = 'usr_123';
|
||||
```
|
||||
|
||||
### Query Examples
|
||||
|
||||
```sql
|
||||
-- Get users with push notifications enabled
|
||||
SELECT id, email, preferences->'notifications'->>'pushEnabled' as push_enabled
|
||||
FROM users
|
||||
WHERE preferences->'notifications'->>'pushEnabled' = 'true';
|
||||
|
||||
-- Get users with feeding reminders disabled
|
||||
SELECT id, email
|
||||
FROM users
|
||||
WHERE preferences->'notifications'->>'feedingReminders' = 'false';
|
||||
|
||||
-- Update a specific preference
|
||||
UPDATE users
|
||||
SET preferences = jsonb_set(
|
||||
preferences,
|
||||
'{notifications,pushEnabled}',
|
||||
'false'
|
||||
)
|
||||
WHERE id = 'usr_123';
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Default Behavior
|
||||
|
||||
### New Users
|
||||
- All notification preferences default to **enabled**
|
||||
- Push notifications are **enabled** by default
|
||||
- Users can customize after onboarding
|
||||
|
||||
### Existing Users (Migration)
|
||||
- Existing users without preferences get defaults on first access
|
||||
- No database migration needed - handled by service layer
|
||||
- Backward compatible with old preference format
|
||||
|
||||
---
|
||||
|
||||
## Key Features
|
||||
|
||||
✅ **Persistent Across Sessions** - Settings saved to database, not local storage
|
||||
✅ **Multi-Device Sync** - Same preferences across all user's devices
|
||||
✅ **Granular Control** - Enable/disable specific notification types
|
||||
✅ **API-Driven** - RESTful endpoints for all preference operations
|
||||
✅ **Type-Safe** - Full TypeScript validation with DTOs
|
||||
✅ **Default Values** - Sensible defaults ensure notifications work out-of-box
|
||||
✅ **Audit Trail** - All changes logged via user updates
|
||||
✅ **Privacy-Focused** - User controls all notification types
|
||||
|
||||

|
||||
|
||||
## Testing
|
||||
|
||||
### Backend Testing
|
||||
|
||||
```bash
|
||||
# Get preferences
|
||||
curl -H "Authorization: Bearer $TOKEN" \
|
||||
http://localhost:3020/api/v1/preferences
|
||||
|
||||
# Disable push notifications
|
||||
curl -X POST \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
http://localhost:3020/api/v1/preferences/notifications/push/disable
|
||||
|
||||
# Update specific preferences
|
||||
curl -X PUT \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"feedingReminders": false, "sleepReminders": false}' \
|
||||
http://localhost:3020/api/v1/preferences/notifications
|
||||
```
|
||||
|
||||
### Frontend Testing

1. Open web app at `http://maternal.noru1.ro`
|
||||
2. Navigate to Settings page
|
||||
3. Toggle push notifications ON
|
||||
4. Verify preference saved in database
|
||||
5. Toggle push notifications OFF
|
||||
6. Verify preference updated
|
||||
7. Refresh page - verify setting persists
|
||||
|
||||
---
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Planned Features
|
||||
- [ ] **Per-Child Preferences** - Different notification settings per child
|
||||
- [ ] **Time-Based Quiet Hours** - Disable notifications during sleep hours
|
||||
- [ ] **Notification Frequency Control** - Limit number of notifications per day
|
||||
- [ ] **Smart Suggestions** - ML-based preference recommendations
|
||||
- [ ] **Bulk Operations** - Enable/disable all notification types at once
|
||||
- [ ] **Advanced UI** - Rich settings page with toggles for each type
|
||||
|
||||
### API Extensions
|
||||
- [ ] `GET /api/v1/preferences/notifications/children/:childId` - Per-child preferences
|
||||
- [ ] `PUT /api/v1/preferences/notifications/quiet-hours` - Set quiet hours
|
||||
- [ ] `POST /api/v1/preferences/notifications/bulk-update` - Bulk enable/disable
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Issue**: Preferences not persisting
|
||||
**Solution**: Check JWT token is valid and user has permissions
|
||||
|
||||
**Issue**: Push still sending when disabled
|
||||
**Solution**: Clear browser service worker cache, re-subscribe
|
||||
|
||||
**Issue**: Preferences showing as `null`
|
||||
**Solution**: Service returns defaults for null values - working as intended
|
||||
|
||||
**Issue**: Cannot update preferences
|
||||
**Solution**: Ensure request body matches `NotificationPreferencesDto` validation
|
||||
|
||||

|
||||
|
||||

## ✅ IMPLEMENTATION SUMMARY (October 8, 2025)
|
||||
|
||||
### What Was Implemented
|
||||
|
||||
#### Backend (NestJS)
|
||||
✅ **Database Schema** - `push_subscriptions` table already exists in production
|
||||
✅ **TypeORM Entity** - `src/database/entities/push-subscription.entity.ts`
|
||||
✅ **Push Service** - `src/modules/push/push.service.ts` with full VAPID integration
|
||||
✅ **Push Controller** - `src/modules/push/push.controller.ts` with REST endpoints
|
||||
✅ **Push Module** - `src/modules/push/push.module.ts` integrated into AppModule
|
||||
✅ **Notifications Integration** - Auto-sends push when creating notifications
|
||||
✅ **VAPID Keys** - Generated and configured in `.env`
|
||||
|
||||
**API Endpoints Created:**
|
||||
- `GET /api/v1/push/vapid-public-key` - Get VAPID public key
|
||||
- `POST /api/v1/push/subscriptions` - Subscribe to push notifications
|
||||
- `GET /api/v1/push/subscriptions` - List user subscriptions
|
||||
- `DELETE /api/v1/push/subscriptions` - Unsubscribe
|
||||
- `POST /api/v1/push/test` - Send test notification
|
||||
- `GET /api/v1/push/statistics` - Get push statistics
|
||||
|
||||
#### Frontend (Next.js)
|
||||
✅ **Service Worker** - `public/push-sw.js` for handling push events
|
||||
✅ **Push Utilities** - `lib/push-notifications.ts` with full API client
|
||||
✅ **UI Component** - `components/PushNotificationToggle.tsx` with toggle switch
|
||||
✅ **Browser Support** - Chrome, Firefox, Edge, Safari (iOS 16.4+ PWA)
|
||||
|
||||
**Key Features:**
|
||||
- No Firebase/OneSignal dependency (pure Web Push/VAPID)
|
||||
- Automatic error handling (404/410 auto-deactivates)
|
||||
- Multi-device support per user
|
||||
- Device type and browser tracking
|
||||
- Statistics and monitoring built-in
|
||||
- Auto-cleanup of inactive subscriptions
|
||||
|
||||
### Environment Configuration
|
||||
|
||||
```ini
|
||||
PUSH_NOTIFICATIONS_ENABLED=true
|
||||
VAPID_PUBLIC_KEY=BErlB-L0pDfv1q3W0SHs3ZXqyFi869OScpt5wJ2aNu2KKbLxLj4a-YO6SyuAamjRG_cqY65yt2agyXdMdy2wEXI
|
||||
VAPID_PRIVATE_KEY=Rg47clL1z4wSpsBTx4yIOIHHX9qh1W5TyBZwBfPIesk
|
||||
VAPID_SUBJECT=mailto:hello@parentflow.com
|
||||
PUSH_DEFAULT_TTL=86400
|
||||
PUSH_BATCH_SIZE=100
|
||||
```
|
||||
|
||||
### Integration with Existing Features
|
||||
|
||||
The push notification system automatically sends notifications for:
|
||||
- ✅ Feeding reminders (based on patterns)
|
||||
- ✅ Sleep reminders (nap time suggestions)
|
||||
- ✅ Diaper change reminders
|
||||
- ✅ Medication reminders
|
||||
- ✅ Growth tracking reminders
|
||||
- ✅ Milestone alerts
|
||||
- ✅ Pattern anomalies
|
||||
|
||||
### Testing Status
|
||||
|
||||
✅ Backend compilation successful (0 errors)
|
||||
✅ Backend running on port 3020
|
||||
✅ Service Worker created
|
||||
✅ UI component created
|
||||
⏳ End-to-end testing pending
|
||||
⏳ Multi-device testing pending
|
||||
⏳ Browser compatibility testing pending
|
||||
|
||||
### Next Steps
|
||||
|
||||
1. **Add Settings Persistence** - Store notification preferences in database
|
||||
2. **Test End-to-End Flow** - Enable push in web app and verify
|
||||
3. **Production Deployment** - Generate production VAPID keys
|
||||
4. **Monitoring Setup** - Configure error tracking and analytics
|
||||
5. **Rate Limiting** - Add rate limits to push endpoints
|
||||
