When ran the server listens for GET requests at /qr endpoint with a url parameter from the query string and uses the qrcode library to create a QR code image. It then saves the image to a buffer and creates a response object with the contents of the buffer. Finally, it returns the response object with the QR code image. It also automatically downloads it.
