## Overview

This guide shows how to integrate the DailyNotification plugin with the existing TimeSafari PWA architecture, specifically the `CapacitorPlatformService` and `PlatformServiceMixin` patterns. The integration maintains the same interfaces and patterns while adding enhanced functionality.

## TimeSafari PWA Architecture Analysis

### Existing Architecture Components

#### 1. CapacitorPlatformService
- **Location**: `src/services/platforms/CapacitorPlatformService.ts`
- **Purpose**: Provides native mobile functionality through Capacitor plugins
- **Features**: File system, camera, SQLite database operations, platform detection
- **Key Methods**: `dbQuery`, `dbExec`, `takePicture`, `writeFile`, `getCapabilities`

#### 2. PlatformServiceFactory
- **Location**: `src/services/PlatformServiceFactory.ts`
- **Purpose**: Factory pattern for creating platform-specific service implementations
- **Pattern**: Singleton pattern with environment-based platform detection
- **Platforms**: `capacitor`, `electron`, `web` (default)

#### 3. PlatformServiceMixin
- **Location**: `src/utils/PlatformServiceMixin.ts`
- **Purpose**: Vue.js mixin providing cached platform service access and utility methods
- **Features**: Database operations, settings management, contact management, logging
- **Key Methods**: `$db`, `$exec`, `$settings`, `$contacts`, `$saveSettings`

### Existing TimeSafari Patterns

#### 1. Settings Management
```typescript
// Existing TimeSafari settings pattern
const settings = await this.$settings();
const activeDid = settings.activeDid;
const starredPlanHandleIds = settings.starredPlanHandleIds;
const apiServer = settings.apiServer;
```

#### 2. Database Operations
```typescript
// Existing TimeSafari database pattern
const result = await this.$dbQuery("SELECT * FROM settings WHERE id = 1");
const contacts = await this.$contacts();
await this.$saveSettings({ starredPlanHandleIds: newIds });
```

#### 3. Platform Detection
```typescript
// Existing TimeSafari platform detection
if (this.isCapacitor) {
  // Native mobile functionality
} else {
  // Web browser functionality
}
```

## DailyNotification Plugin Integration

### Integration Strategy

The DailyNotification plugin integrates with the existing TimeSafari PWA architecture by:

1. **Extending CapacitorPlatformService**: Adding DailyNotification functionality to the existing platform service
2. **Using PlatformServiceMixin**: Leveraging existing database and settings patterns
3. **Maintaining Interfaces**: Keeping the same method signatures and behavior
4. **Platform Detection**: Only initializing on Capacitor platforms

### Enhanced CapacitorPlatformService

```typescript
export class EnhancedCapacitorPlatformService {
  private platformService = PlatformServiceFactory.getInstance();
  private dailyNotificationService: DailyNotification | null = null;
  private integrationService: TimeSafariIntegrationService | null = null;

  async initializeDailyNotification(): Promise<void> {
    // Get existing TimeSafari settings
    const settings = await this.getTimeSafariSettings();
    
    // Configure plugin with TimeSafari data
    await DailyNotification.configure({
      timesafariConfig: {
        activeDid: settings.activeDid,
        endpoints: {
          projectsLastUpdated: `${settings.apiServer}/api/v2/report/plansLastUpdatedBetween`
        },
        starredProjectsConfig: {
          enabled: true,
          starredPlanHandleIds: settings.starredPlanHandleIds,
          lastAckedJwtId: settings.lastAckedStarredPlanChangesJwtId,
          fetchInterval: '0 8 * * *'
        }
      },
      networkConfig: {
        baseURL: settings.apiServer,
        timeout: 30000
      }
    });
  }

  async loadNewStarredProjectChanges(): Promise<StarredProjectsResponse> {
    // Enhanced version of existing TimeSafari method
    const settings = await this.getTimeSafariSettings();
    
    if (!settings.activeDid || !settings.starredPlanHandleIds?.length) {
      return { data: [], hitLimit: false };
    }

    // Use plugin's enhanced fetching
    return await this.integrationService!.getStarredProjectsWithChanges(
      settings.activeDid,
      settings.starredPlanHandleIds,
      settings.lastAckedStarredPlanChangesJwtId
    );
  }
}
```

### Vue.js Component Integration

```typescript
export const TimeSafariDailyNotificationMixin = {
  data() {
    return {
      // Existing TimeSafari data
      activeDid: '',
      starredPlanHandleIds: [] as string[],
      lastAckedStarredPlanChangesJwtId: '',
      numNewStarredProjectChanges: 0,
      newStarredProjectChangesHitLimit: false,
      
      // Plugin integration
      enhancedPlatformService: null as EnhancedCapacitorPlatformService | null
    };
  },

  async mounted() {
    // Initialize DailyNotification when component mounts (only on Capacitor)
    if (this.isCapacitor) {
      await this.initializeDailyNotification();
    }
  },

  methods: {
    async initializeDailyNotification(): Promise<void> {
      this.enhancedPlatformService = new EnhancedCapacitorPlatformService();
      await this.enhancedPlatformService.initializeDailyNotification();
    },

    async loadNewStarredProjectChanges(): Promise<void> {
      if (this.isCapacitor && this.enhancedPlatformService) {
        // Use plugin-enhanced method on Capacitor
        const result = await this.enhancedPlatformService.loadNewStarredProjectChanges();
        this.numNewStarredProjectChanges = result.data.length;
        this.newStarredProjectChangesHitLimit = result.hitLimit;
      } else {
        // Use existing web method in browser
        await this.loadNewStarredProjectChangesWeb();
      }
    }
  }
};
```

## Integration Steps

### Step 1: Install the Plugin

```bash
# In TimeSafari PWA project
npm install ssh://git@173.199.124.46:222/trent_larson/daily-notification-plugin.git
```

### Step 2: Create Enhanced Platform Service

Create `src/services/platforms/EnhancedCapacitorPlatformService.ts`:

```typescript
import { DailyNotification } from '@timesafari/daily-notification-plugin';
import { TimeSafariIntegrationService } from '@timesafari/daily-notification-plugin';
import { PlatformServiceFactory } from '@/services/PlatformServiceFactory';

export class EnhancedCapacitorPlatformService {
  // Implementation from the example above
}
```

### Step 3: Extend PlatformServiceMixin

Add to `src/utils/PlatformServiceMixin.ts`:

```typescript
export const PlatformServiceMixin = {
  // ... existing mixin code ...
  
  methods: {
    // ... existing methods ...
    
    /**
     * Initialize DailyNotification plugin (Capacitor only)
     */
    async $initializeDailyNotification(): Promise<void> {
      if (this.isCapacitor) {
        const enhancedService = new EnhancedCapacitorPlatformService();
        await enhancedService.initializeDailyNotification();
        this._enhancedPlatformService = enhancedService;
      }
    },

    /**
     * Enhanced loadNewStarredProjectChanges method
     */
    async $loadNewStarredProjectChanges(): Promise<StarredProjectsResponse> {
      if (this.isCapacitor && this._enhancedPlatformService) {
        return await this._enhancedPlatformService.loadNewStarredProjectChanges();
      } else {
        // Fall back to existing web method
        return await this.$loadNewStarredProjectChangesWeb();
      }
    }
  }
};
```

### Step 4: Update Vue Components

In your existing TimeSafari Vue components:

```typescript
export default defineComponent({
  name: 'TimeSafariHomeView',
  
  mixins: [PlatformServiceMixin],
  
  async mounted() {
    // Initialize DailyNotification (only on Capacitor)
    if (this.isCapacitor) {
      await this.$initializeDailyNotification();
    }
  },

  methods: {
    async loadNewStarredProjectChanges() {
      // Use enhanced method
      const result = await this.$loadNewStarredProjectChanges();
      this.numNewStarredProjectChanges = result.data.length;
      this.newStarredProjectChangesHitLimit = result.hitLimit;
    }
  }
});
```

## Configuration Mapping

### TimeSafari Settings → Plugin Configuration

| TimeSafari Setting | Plugin Configuration | Purpose |
|-------------------|---------------------|---------|
| `settings.activeDid` | `timesafariConfig.activeDid` | User authentication |
| `settings.apiServer` | `networkConfig.baseURL` | API endpoint |
| `settings.starredPlanHandleIds` | `starredProjectsConfig.starredPlanHandleIds` | Project IDs to fetch |
| `settings.lastAckedStarredPlanChangesJwtId` | `starredProjectsConfig.lastAckedJwtId` | Pagination token |

### Existing Methods → Enhanced Methods

| Existing Method | Enhanced Method | Enhancement |
|----------------|----------------|-------------|
| `loadNewStarredProjectChanges()` | `$loadNewStarredProjectChanges()` | Background fetching, structured logging |
| `getStarredProjectsWithChanges()` | `integrationService.getStarredProjectsWithChanges()` | Retry logic, circuit breaker |
| Settings storage | Plugin storage adapter | Tiered storage, TTL management |

## Platform-Specific Behavior

### Capacitor (Android/iOS)
- **Plugin Enabled**: Full DailyNotification functionality
- **Background Fetching**: WorkManager (Android), BGTaskScheduler (iOS)
- **Notifications**: Native notification channels and categories
- **Storage**: SQLite with plugin's tiered storage system

### Web Browser
- **Plugin Disabled**: Uses existing TimeSafari web code
- **No Background Fetching**: Limited to browser capabilities
- **No Native Notifications**: Uses web notifications API
- **Storage**: Existing TimeSafari storage patterns

### Electron
- **Plugin Enabled**: Desktop-specific functionality
- **Background Tasks**: Electron main process
- **Desktop Notifications**: Native desktop notifications
- **Storage**: SQLite with plugin's tiered storage system

## Benefits of Integration

### 1. Same Interface, Enhanced Functionality
- Existing `loadNewStarredProjectChanges()` method works exactly the same
- Enhanced with background fetching, structured logging, and error handling
- No changes required to existing UI code

### 2. Leverages Existing TimeSafari Patterns
- Uses existing `PlatformServiceMixin` for database operations
- Integrates with existing settings management
- Maintains existing platform detection patterns

### 3. Platform-Optimized Performance
- **Capacitor**: Native mobile optimizations with WorkManager/BGTaskScheduler
- **Web**: Falls back to existing web code seamlessly
- **Electron**: Desktop-specific optimizations

### 4. Enhanced Observability
- Structured logging with event IDs
- Performance metrics and monitoring
- Error tracking and analysis
- Health checks and status monitoring

## Migration Strategy

### Phase 1: Parallel Implementation
1. **Keep existing code unchanged**
2. **Add enhanced platform service alongside existing code**
3. **Test both implementations in parallel**
4. **Compare results to ensure compatibility**

### Phase 2: Gradual Migration
1. **Replace individual methods one by one**
2. **Use enhanced error handling and logging**
3. **Maintain existing UI and user experience**
4. **Add plugin-specific features gradually**

### Phase 3: Full Integration
1. **Replace all TimeSafari request patterns with plugin**
2. **Remove duplicate code**
3. **Leverage plugin's advanced features**
4. **Optimize performance with plugin's caching and batching**

## Testing Strategy

### 1. Platform-Specific Testing
```typescript
// Test on different platforms
const testPlatforms = async () => {
  if (Capacitor.getPlatform() === 'android') {
    // Test Android-specific functionality
  } else if (Capacitor.getPlatform() === 'ios') {
    // Test iOS-specific functionality
  } else {
    // Test web fallback
  }
};
```

### 2. Parallel Testing
```typescript
// Test both implementations
const testBothImplementations = async () => {
  // Existing TimeSafari implementation
  const existingResult = await this.loadNewStarredProjectChangesOriginal();
  
  // Plugin-enhanced implementation
  const pluginResult = await this.$loadNewStarredProjectChanges();
  
  // Compare results
  assert.deepEqual(existingResult, pluginResult);
};
```

### 3. Performance Testing
```typescript
// Compare performance
const performanceTest = async () => {
  const start = Date.now();
  await this.$loadNewStarredProjectChanges();
  const pluginTime = Date.now() - start;
  
  console.log('Plugin performance:', pluginTime);
};
```

## Common Integration Patterns

### 1. Settings Integration
```typescript
// Get TimeSafari settings
const settings = await this.$settings();

// Configure plugin with settings
await DailyNotification.configure({
  timesafariConfig: {
    activeDid: settings.activeDid,
    starredPlanHandleIds: settings.starredPlanHandleIds
  }
});
```

### 2. Database Integration
```typescript
// Store plugin results in TimeSafari database
await this.$dbExec(
  "INSERT OR REPLACE INTO temp (id, data) VALUES (?, ?)",
  ['starred_projects_latest', JSON.stringify(result)]
);
```

### 3. Error Handling Integration
```typescript
// Use existing TimeSafari error handling patterns
try {
  const result = await this.$loadNewStarredProjectChanges();
  // Handle success
} catch (error) {
  // Use existing TimeSafari error logging
  await this.$logError(`Failed to load starred projects: ${error.message}`);
}
```

## Troubleshooting

### Common Issues

#### 1. Plugin Not Initializing
```typescript
// Check platform detection
if (!this.isCapacitor) {
  console.log('Plugin only works on Capacitor platforms');
  return;
}
```

#### 2. Settings Not Found
```typescript
// Ensure settings are loaded
const settings = await this.$settings();
if (!settings.activeDid) {
  console.log('No active DID found');
  return;
}
```

#### 3. Database Connection Issues
```typescript
// Check database connection
try {
  await this.$dbQuery("SELECT 1");
} catch (error) {
  console.error('Database connection failed:', error);
}
```

### Debug Methods

#### 1. Plugin Status
```typescript
const status = await this.getDailyNotificationStatus();
console.log('Plugin status:', status);
```

#### 2. Settings Debug
```typescript
await this.$debugMergedSettings(this.activeDid);
```

#### 3. Performance Debug
```typescript
const metrics = await DailyNotification.getMetrics();
console.log('Plugin metrics:', metrics);
```
