Week 10: Notifications & Activity — Dec 28, 2024 – Jan 3, 2025
TL;DR: Real-time notification system with in-app alerts, email digests, and an activity feed that tracks every significant action across the platform.
Highlights This Week
- Built real-time notification system with WebSocket delivery
- Added configurable notification preferences per user
- Implemented activity feed with filterable event history
Notification Architecture
Notifications are generated by domain events (job assigned, invoice paid, estimate approved) and delivered through multiple channels: in-app bell icon, email digest, and future SMS. Users control which events trigger which channels through a granular preferences panel.
How It Works
Domain events publish to an internal event bus. Notification handlers subscribe to events, format the message per channel, and dispatch. In-app notifications use WebSocket for real-time delivery. Email digests batch notifications on a configurable schedule (immediate, hourly, daily).
