Code Examples

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,
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
