Analysis of this issue:

Difficulty: Hard (4/5)
Estimated time: 15-20 hours

Implementation details:
This is a complex feature requiring several major components:

Backend Requirements:

1. WebSocket implementation using Django Channels
2. New database models for:
   • Chat messages
   • Chat rooms/conversations
   • User presence tracking
3. Message persistence and retrieval API
4. Authentication integration with WebSocket connections

Frontend Requirements:

1. Real-time chat UI components:
   • Chat window
   • Message input
   • User list/presence indicators
   • Unread message notifications
2. WebSocket service for real-time communication
3. Message history management
4. Offline/reconnection handling

Steps to implement:

1. Set up Django Channels for WebSocket support
2. Create database models and migrations
3. Implement WebSocket consumers in Django
4. Create REST endpoints for message history
5. Develop Angular chat components
6. Implement WebSocket service in Angular
7. Add real-time presence tracking
8. Implement message persistence
9. Add error handling and reconnection logic
10. Write tests for all components

Technical Considerations:

• Message delivery confirmation
• Handling offline users
• Message pagination for history
• Rate limiting to prevent abuse
• Data persistence strategy
• Scaling considerations for WebSocket connections
• Security considerations for WebSocket authentication

This feature requires significant planning and architecture decisions before implementation. It would be beneficial to break this down into smaller, manageable sub-tasks that can be implemented incrementally.
