Compliant code​

The application handles connections without storing parameters in source code

const request = require('request');
const prepareView: function(req, res) {
  getAccessToken().then(function(accessToken) {
    getEmbedToken(accessToken, req.params.groupId, req.params.dashboardId).then(function(embedToken) {
      res.render('index', {
        dashboardId: req.params.dashboardId,
        embedToken,
        embedUrl: POWERBI_URL + req.params.dashboardId + '&groupId=' + req.params.groupId
      });
    });
  });
}

Non compliant code​

There are Power BI credentials stored in the source code

const request = require('request');
const getAccessToken = function () {
  return new Promise(function (resolve, reject) {
    const url = POWERBI_URL;
    const username = 'myUserName';
    const password = 'myPassword';
    const clientId = 'myClientId';

    //Remaining code to handle connection to Token
  }
};
