📌 Important Files in Source Code

WebSocket Implementation:

• File: services/emergency_service/main.py
• Key Classes:
  • WebSocketManager (line ~96) - Manages all WebSocket connections
  • websocket_endpoint() (line ~393) - Main WebSocket handler
• Key Methods:
  • connect() - Establish connection
  • disconnect() - Close connection
  • broadcast_alert() - Send to multiple users
  • send_personal_message() - Send to single user

Related Files:

• shared/auth.py - JWT token handling
• services/emergency_service/models.py - Database models
• services/emergency_service/schemas.py - Data schemas

---

🚀 Deployment Checklist

• Run python test_ws_quick.py - Verify connection
• Run python test_ws_full.py - Test full flow
• Check logs for errors
• Verify JWT tokens are generated
• Test with 10+ concurrent clients
• Load test with 100+ concurrent users
• Enable monitoring (Prometheus)
• Set up alerting
• Configure Redis for scaling
• Deploy to staging first

🔧 Troubleshooting Quick Links

"WebSocket connection refused"

→ Check that Emergency Service is running on port 8002

"Invalid JWT token"

→ Regenerate token: python register_test_user.py

"No messages received"

→ That's normal - need another user to create SOS alert

"HTTP endpoints return 500"

→ Expected limitation - WebSocket works independently

📞 Support Information

Issue: Connection works but no messages

Possible causes:
1. No other users nearby creating SOS
2. SOS not being created
3. Location Service not running

Solution: Create SOS alert through API endpoint

Issue: Intermittent disconnections

Possible causes:
1. Network issues
2. Server overload
3. Client timeout

Solution: Implement retry logic with exponential backoff

Issue: High memory usage

Possible causes:
1. Too many concurrent connections
2. Memory leak in server
3. Messages not being garbage collected

Solution: Monitor and scale horizontally
