# Implementation Plan: Callback System & Dual Scheduling
**Document Created**: 2025-08-26 11:17:26 UTC
**Author**: Matthew Raymer
**Status**: 📋 **PLANNING PHASE**
**Priority**: 🔴 **HIGH** - Core functionality enhancement required
## 🎯 **IMPLEMENTATION OVERVIEW**
### **Goal**
Transform the Daily Notification Plugin from a single-method scheduler to a dual-method system with comprehensive callback support for external service integration.
### **Key Changes**
1. **Add callback system** for API, database, and reporting services
2. **Implement dual scheduling methods**:
- `scheduleContentFetch()` - API calls and database storage
- `scheduleUserNotification()` - Database retrieval and user notification
3. **Maintain backward compatibility** with existing API

## 🔧 **TECHNICAL IMPLEMENTATION DETAILS**
### **Callback Execution Model**
```typescript
// Asynchronous callback execution with error handling
async executeCallback(type: CallbackType, data: any): Promise<void> {
try {
const callbacks = this.getCallbacks(type);
const promises = callbacks.map(callback =>
this.executeSingleCallback(callback, data)
);
await Promise.allSettled(promises);
} catch (error) {
this.handleCallbackError(type, error);
}
}
```
### **Error Handling Strategy**
```typescript
// Comprehensive error handling for callbacks
private handleCallbackError(type: CallbackType, error: Error): void {
// Log error for debugging
this.logger.error(`Callback execution failed for type: ${type}`, error);
// Execute error callbacks if available
this.executeErrorCallbacks(type, error);
// Fallback to default error handling
this.executeDefaultErrorHandling(type, error);
}
```
### **Retry and Fallback Logic**
```typescript
// Retry logic with exponential backoff
async executeWithRetry<T>(
operation: () => Promise<T>,
maxRetries: number = 3,
baseDelay: number = 1000
): Promise<T> {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
return await operation();
} catch (error) {
if (attempt === maxRetries) throw error;
const delay = baseDelay * Math.pow(2, attempt - 1);
await this.sleep(delay);
}
}
throw new Error('Max retries exceeded');
}
```
