You got it! The process is very similar on Windows. You'll still use your mobile hotspot to create a local network, and then connect all devices (including your Windows PC running the server) to that same hotspot.

Here's how to do it on Windows:

1. Connect your Windows PC to your Mobile Hotspot:

   • On your mobile phone, enable your personal hotspot.
   • On your Windows PC, go to your Wi-Fi settings and connect to your mobile hotspot's Wi-Fi network. Your Windows PC will get a local IP address from your phone's hotspot (e.g., something like 192.168.x.x or 10.x.x.x).

2. Find your Windows PC's IP Address on the Hotspot Network:

   • Open Command Prompt or PowerShell on your Windows PC.

   • Type the following command and press Enter:

     ipconfig
   • Look for the section related to your Wi-Fi adapter (it might be labeled "Wireless LAN adapter Wi-Fi" or similar).

   • Find the line that says IPv4 Address. . . . . . . . . . . :. The number next to it is your Windows PC's local IP address on the hotspot network.

     • Example: If you see IPv4 Address. . . . . . . . . . . : 192.168.137.1, then 192.168.137.1 is your IP.

3. Start your Node.js Server on the Windows PC:

   • Open your VS Code terminal (or Command Prompt/PowerShell) in your attendance-web-app directory.
   • Run npm start.
   • The server will log Server running on http://localhost:3000 and Access the frontend at http://localhost:3000. Remember, for other devices, you'll use the actual IP.

4. Connect Other Devices (e.g., another phone, another laptop) to the Same Mobile Hotspot:

   • Ensure these devices are also connected to the exact same mobile hotspot that your Windows PC is connected to.

5. Access the Application from Other Devices:

   • On the other devices, open a web browser.
   • In the address bar, type the Windows PC's IP address you found in step 2, followed by :3000.
   • For example, if your Windows PC's IP is 192.168.137.1, you would type: http://192.168.137.1:3000

This setup will restrict access to your attendance application only to devices connected to your specific mobile hotspot.

Great! Thanks for providing the ipconfig output.

From your output, under the "Wireless LAN adapter Wi-Fi" section, you can see:

IPv4 Address. . . . . . . . . . . : 10.175.42.88

This is the IP address of your Windows PC on your current Wi-Fi network (which should be your mobile hotspot).

So, to access your attendance application from other devices connected to the same mobile hotspot, you should use this address:

http://10.175.42.88:3000

Make sure your Node.js server is running (npm start) on your Windows PC, and then try opening that URL in a browser on another device connected to your hotspot.
