QR code reader javascript

Content

Hi,

I'm trying to user qr code reader Javascript and imported as a resource. However, i get the "qrcode is not defined" error, am I declaring the Javascript incorrectly (see code snippet)?

Please advise, thank you

Code Snippet

define(["mobileApps/test1/resources/qrcode.js"], function(qrcode) {
  'use strict';

  var PageModule = function PageModule() {};

  return PageModule;
  
});



function openQRCamera(node) {
  var reader = new FileReader();
  reader.onload = function() {
    node.value = "";
    qrcode.callback = function(res) {
      if(res instanceof Error) {
        alert("No QR code found. Please make sure the QR code is within the camera's frame and try again.");
      } else {
        node.parentNode.previousElementSibling.value = res;
