November was dedicated to building the core product features: real-time collaboration and data synchronization. The implementation supports offline-first operation with seamless conflict resolution when connectivity returns.
Key Changes & Features
- Real-Time Collaboration
- Implemented WebSocket-based real-time updates for shared workspace changes.
- Built an operational transformation engine for concurrent text editing without conflicts.
- Added presence indicators showing which team members are viewing or editing content.
- Offline-First Architecture
- Implemented local SQLite storage for offline data access and modification.
- Created a sync engine that queues changes and reconciles with the server on reconnection.
- Added conflict detection with user-friendly resolution UI for divergent edits.
- Push Notifications
- Integrated Apple Push Notification service (APNs) for real-time alerts.
- Implemented notification categories with actionable buttons for quick responses.
- Added notification preferences allowing users to customize alert types and schedules.
Technologies & Languages
- Swift: Core Data integration and sync engine implementation.
- TypeScript: WebSocket server and operational transformation logic.
- Redis: Pub/sub for broadcasting real-time updates across server instances.
Patterns & Architecture
- Event Sourcing: Changes are stored as immutable events, enabling replay and audit trails.
- CRDT-Inspired Sync: Conflict-free data structures for automatic merge of concurrent changes.
- Background Tasks: iOS background app refresh keeps local data synchronized.
