QR Code Generator

Generate qr.png in the project root with the current ngrok tunnel URL.

Steps

1. Query the ngrok local API to get the active tunnel URL:

   curl -s http://localhost:4040/api/tunnels
   

2. Extract the public_url from the response (the HTTPS tunnel pointing to localhost:3000).
3. Generate the QR code using Python:

   python3 -c "
   import qrcode
   img = qrcode.make('<URL>')
   img.save('qr.png')
   "
   

4. Report the URL and confirm the file was saved.

Notes

• If ngrok is not running, tell the user to start it first (ngrok http 3000).
• If the qrcode Python package is missing, install it: pip3 install qrcode[pil].
• Always overwrite the existing qr.png.
