I am having trouble understanding the short documentation for quickbooks-js https://github.com/RappidDevelopment/quickbooks-js/blob/master/README.md

In the qbXMLHandler where do the queries need to placed? For example I need all the information returned from a invoice and sent to a React application in JSON.

The goal is to pull data from the desktop quickbooks application and send it to the React application using Node.

const convert = data2xml({
  xmlHeader:
    '<?xml version="1.0" encoding="utf-8"?>\n<?qbxml version="13.0"?>\n',
});

module.exports = {
  /**
   * Builds an array of qbXML commands
   * to be run by QBWC.
   *
   * @param callback(err, requestArray)
   */
  fetchRequests: function (callback) {
    buildRequests(callback);
    console.log(buildRequests(callback));
  },

  /**
   * Called when a qbXML response
   * is returned from QBWC.
   *
   * @param response - qbXML response
   */
  handleResponse: function (response) {
    console.log(response);
  },

  /**
   * Called when there is an error
   * returned processing qbXML from QBWC.
   *
   * @param error - qbXML error response
   */
  didReceiveError: function (error) {
    console.log(error);
  },
};

function buildRequests(callback) {
  let requests = new Array();
  let xml = convert("QBXML", {
    QBXMLMsgsRq: {
      _attr: { onError: "stopOnError" },
      ItemInventoryQueryRq: {
        MaxReturned: 1000,
      },
    },
  });
  requests.push(xml);

  return callback(null, requests);
}
