# Daily Notification Plugin: Callback System & Dual Scheduling Research
|
||||
|
||||
**Document Created**: 2025-08-26 11:30:29 UTC
|
||||
**Author**: Matthew Raymer
|
||||
**Status**: ✅ **RESEARCH COMPLETE** - Ready for implementation planning
|
||||
**Branch**: research/notification-plugin-enhancement
|
||||
**Mode**: Research & Analysis (investigation, documentation)
|
||||
|
||||
---
|
||||
|
||||
## 🎯 **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
|
||||
|
||||
### **Implementation Complexity**: 🔴 **HIGH** - Requires significant architecture changes
|
||||
|
||||

|
||||
|
||||
## 📋 **USER REQUIREMENTS ANALYSIS**
|
||||
|
||||
### **User Feedback Summary**
|
||||
> "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 calls out to a reporting service and then saving in the DB). The other is that I believe we need two 'schedule' methods, one that does the call-API-store-in-DB function and the other that does the retrieve-from-DB-and-notify-user function."
|
||||
|
||||
### **Core Requirements Identified**
|
||||
|
||||
#### **1. Callback System Integration**
|
||||
- **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
|
||||
|
||||
#### **2. Dual Scheduling Methods**
|
||||
- **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 System Architecture**
|
||||
|
||||
#### **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
|
||||
