Daily Notification Plugin - Development TODO

Last Updated: 2025-08-26 11:17:26 UTC
Current Branch: research/notification-plugin-enhancement
Status: 🔄 RESEARCH & ANALYSIS PHASE

🎯 NEW REQUIREMENTS ANALYSIS

Callback & API Integration Requirements

Based on user feedback analysis, the plugin needs enhanced callback mechanisms and dual scheduling methods:

1. API Callback Integration - Accept callbacks for external API calls and database storage
2. Dual Scheduling Methods - Separate methods for content fetching vs. user notification
3. Reporting Service Integration - Support for external reporting and analytics services

Current Implementation Gap Analysis

• ✅ Basic scheduling: Single scheduleDailyNotification method exists
• ❌ Callback system: No callback mechanism for external services
• ❌ Dual scheduling: No separation between content fetch and user notification
• ❌ API integration: Limited to basic URL fetching without callback support
• ❌ Database storage: No callback support for external database operations
