## 🎯 **EXECUTIVE SUMMARY** | 
				
			|||
 | 
				
			|||
### **Research Objective** | 
				
			|||
 | 
				
			|||
Analyze user feedback regarding the Daily Notification Plugin's need for | 
				
			|||
enhanced callback mechanisms and dual scheduling methods to support external | 
				
			|||
service integration. | 
				
			|||
 | 
				
			|||
### **Key Findings** | 
				
			|||
 | 
				
			|||
1. **Callback System Required**: Plugin needs to accept callbacks for API | 
				
			|||
   calls, database operations, and reporting services | 
				
			|||
2. **Dual Scheduling Architecture**: Need separate methods for content | 
				
			|||
   fetching vs. user notification | 
				
			|||
3. **External Service Integration**: Support for reporting services and | 
				
			|||
   database operations | 
				
			|||
4. **Backward Compatibility**: Must maintain existing API functionality | 
				
			|||
## Executive Summary | 
				
			|||
 | 
				
			|||
### **Implementation Complexity**: 🔴 **HIGH** | 
				
			|||
Research phase completed for enhancing the daily notification plugin with dual | 
				
			|||
scheduling system and callback mechanisms. Key findings: | 
				
			|||
 | 
				
			|||
Requires significant architecture changes | 
				
			|||
- **Current State**: Basic notification plugin with single scheduling method | 
				
			|||
- **Requirements**: Dual scheduling (content fetch + user notification) + callbacks | 
				
			|||
- **Architecture**: Plugin API design with platform-specific implementations | 
				
			|||
- **Next Phase**: Platform-specific implementation |

## 📋 **USER REQUIREMENTS ANALYSIS** | 
				
			|||
 | 
				
			|||
### **User Feedback Summary** | 
				
			|||
## Requirements Analysis | 
				
			|||
 | 
				
			|||
> "BTW, I still think it's worth starting a branch where we use the | 
				
			|||
> notification plugin, but a note on the plugin itself: seems like it'll | 
				
			|||
> need a couple things. One is to accept some callbacks (eg. for API | 
				
			|||

			|||

			|||
> call-API-store-in-DB function and the other that does the | 
				
			|||
> retrieve-from-DB-and-notify-user function." | 
				
			|||
### User Feedback | 
				
			|||
 | 
				
			|||
### **Core Requirements Identified** | 
				
			|||
- Need callbacks for API calls, database operations, reporting services | 
				
			|||
- Require two distinct scheduling methods: | 
				
			|||
  - Content fetch and storage | 
				
			|||
  - User notification display | 
				
			|||
- Backward compatibility essential | 
				
			|||
 | 
				
			|||
#### **1. Callback System Integration** | 
				
			|||
### Core Requirements | 
				
			|||
 | 
				
			|||
- **API Callbacks**: Handle external API responses and errors | 
				
			|||
- **Database Callbacks**: Support storage and retrieval operations | 
				
			|||
- **Reporting Callbacks**: Integrate with analytics and reporting services | 
				
			|||
- **Error Handling**: Comprehensive callback failure management | 
				
			|||
1. **Dual Scheduling System** | 
				
			|||
   - `scheduleContentFetch()` - API calls, data processing, storage | 
				
			|||
   - `scheduleUserNotification()` - Retrieve data, display notifications | 
				
			|||
2. **Callback Management** | 
				
			|||
   - API callbacks for external services | 
				
			|||
   - Database operation callbacks | 
				
			|||
   - Reporting service callbacks | 
				
			|||
3. **Backward Compatibility** | 
				
			|||
   - Existing `schedule()` method must continue working | 
				
			|||
   - Gradual migration path for existing implementations | 
				
			|||
 | 
				
			|||
#### **2. Dual Scheduling Methods** | 
				
			|||
## Proposed Architecture | 
				
			|||
 | 
				
			|||
- **Method 1**: `scheduleContentFetch()` - API calls and database storage | 
				
			|||
- **Method 2**: `scheduleUserNotification()` - Database retrieval and user | 
				
			|||
  notification | 
				
			|||
- **Separation of Concerns**: Clear distinction between data operations | 
				
			|||
  and user interaction | 
				
			|||
 | 
				
			|||
#### **3. External Service Integration** | 
				
			|||
 | 
				
			|||
- **Reporting Services**: Analytics and metrics collection | 
				
			|||
- **Database Operations**: External database storage and retrieval | 
				
			|||
- **API Integration**: Enhanced HTTP client with callback support | 
				
			|||
- **Retry Logic**: Robust error handling and fallback mechanisms | 
				
			|||
 |

## 🔍 **CURRENT IMPLEMENTATION GAP ANALYSIS** | 
				
			|||
 | 
				
			|||
### **What Exists Today** | 
				
			|||
 | 
				
			|||
- ✅ **Basic scheduling**: Single `scheduleDailyNotification` method | 
				
			|||
- ✅ **URL fetching**: Basic HTTP request support | 
				
			|||
- ✅ **Platform support**: Android, iOS, and Web implementations | 
				
			|||
- ✅ **Interface definitions**: Well-structured TypeScript interfaces | 
				
			|||
 | 
				
			|||
### **What's Missing** | 
				
			|||
 | 
				
			|||
- ❌ **Callback mechanism**: No way to handle external service responses | 
				
			|||
- ❌ **Dual scheduling**: Single method handles everything | 
				
			|||
- ❌ **API integration**: Limited to basic URL fetching | 
				
			|||
- ❌ **Database support**: No callback-based storage operations | 
				
			|||
- ❌ **Reporting integration**: No analytics or metrics callbacks | 
				
			|||
 | 
				
			|||
### **Gap Impact Assessment** | 
				
			|||
 | 
				
			|||
- **User Experience**: Limited to basic notifications without external data | 
				
			|||
- **Integration Capability**: Cannot integrate with reporting or database | 
				
			|||
  services | 
				
			|||
- **Flexibility**: Rigid scheduling without custom logic support | 
				
			|||
- **Scalability**: No way to handle complex notification workflows | 
				
			|||

			|||
 | 
				
			|||
#### **Callback Types** | 
				
			|||
 | 
				
			|||
```typescript | 
				
			|||
interface CallbackSystem { | 
				
			|||
  // API callbacks for external service integration | 
				
			|||
  apiCallbacks: { | 
				
			|||
    onSuccess: (response: any) => Promise<void>; | 
				
			|||
    onError: (error: Error) => Promise<void>; | 
				
			|||
    onRetry: (attempt: number) => Promise<boolean>; | 
				
			|||
  }; | 
				
			|||
   | 
				
			|||
  // Database callbacks for storage operations | 
				
			|||
  databaseCallbacks: { | 
				
			|||
    onStore: (data: any) => Promise<void>; | 
				
			|||
    onRetrieve: (id: string) => Promise<any>; | 
				
			|||
    onError: (error: Error) => Promise<void>; | 
				
			|||
  }; | 
				
			|||
   | 
				
			|||
  // Reporting callbacks for analytics | 
				
			|||
  reportingCallbacks: { | 
				
			|||
    onMetrics: (metrics: NotificationMetrics) => Promise<void>; | 
				
			|||
    onAnalytics: (event: string, data: any) => Promise<void>; | 
				
			|||
  }; | 
				
			|||
} | 
				
			|||
``` | 
				
			|||
 | 
				
			|||
#### **Dual Scheduling Methods** | 
				
			|||
 | 
				
			|||
**Content Fetch Method**: | 
				
			|||
 | 
				
			|||
```typescript | 
				
			|||
async scheduleContentFetch(options: ContentFetchOptions): Promise<void> | 
				
			|||
``` | 
				
			|||
 | 
				
			|||
- Makes API calls to external services | 
				
			|||
- Executes database storage callbacks | 
				
			|||
- Handles retry logic and fallbacks | 
				
			|||
- Reports to analytics/reporting services | 
				
			|||
 | 
				
			|||
**User Notification Method**: | 
				
			|||
 | 
				
			|||
```typescript | 
				
			|||
async scheduleUserNotification(options: UserNotificationOptions): Promise<void> | 
				
			|||
``` | 
				
			|||
 | 
				
			|||
- Retrieves content from database/cache | 
				
			|||
- Executes user notification callbacks | 
				
			|||
- Handles notification display logic | 
				
			|||
- Manages user interaction callbacks | 
				
			|||
