## 📌 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
```
