API Integration

The app connects to an UpSnap server via its REST API:

• Authentication: /api/collections/users/auth-with-password or /api/collections/_superusers/auth-with-password
• Devices: /api/collections/devices/records
• Wake: /api/upsnap/wake/:id
• Sleep: /api/collections/upsnap/sleep/:id
• Reboot: /api/upsnap/reboot/:id
• Shutdown: /api/upsnap/shutdown/:id
• Scan: /api/upsnap/scan

Tech Stack

• React Native: Cross-platform mobile framework
• Expo: Development platform
• TypeScript: Type safety
• React Navigation: Navigation library
• AsyncStorage: Local data persistence

Server Configuration

The app is pre-configured to connect to:

• Server URL: https://wol.f6knight.duckdns.org
• API Base: /api

To change the server URL, modify the API_BASE_URL constant in src/services/api.ts.

Security Notes

• Authentication tokens are stored securely in AsyncStorage
• All API calls require authentication
• Destructive actions (sleep, reboot, shutdown) require confirmation
• Never expose your UpSnap server to the open web without proper security measures

Troubleshooting

Login Issues

• Verify your username/email and password are correct
• Check if you need to log in as admin
• Ensure your UpSnap server is accessible

Network Scan Issues

• Network scanning requires the server to have nmap installed
• Scanning may take several minutes to complete
• Make sure your device and server are on the same network

Device Control Issues

• Verify the device's MAC address is correct
• Ensure Wake-on-LAN is enabled in the device's BIOS/UEFI
• Check that the device is on the same network as the server
• For sleep/shutdown/reboot, ensure the device has the required agent installed
