    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>QRCode Testing</title>
    <script src="./script.js"></script>
</head>
<body>

    <img id="qrcode-container">
    
</body>
</html>

JavaScript:

const nodeqr = require('nodeqr');

function generateQRCode(data, containerId) {
  var qrcode = new nodeqr.QRCode(0, QRCode.ErrorCorrectLevel.L);
  qrcode.addData(data);
  qrcode.make();

  var container = document.getElementById(containerId);

  var qrCodeElement = qrcode.createImgTag(4, 0);

  container.innerHTML = qrCodeElement;
}

document.addEventListener("DOMContentLoaded", function () {
  var dataToEncode = "https://www.example.com";
  var containerId = "qrcode-container";

  generateQRCode(dataToEncode, containerId);
