Integrating Power BI with AngularJS SPAs

Back to index Matthieu Maitre

Power BI reports and dashboards can be integrated into other Web Apps using iframe embedding and the Power BI REST APIs. Code samples on GitHub show how to set it up using an ASP back-end. It is also possible to skip the back-end and code everything using JavaScript on the client side, a great match for AngularJS SPAs.

Power BI integration

Web App registration

First the app needs to be registered with Azure Active Directory (AAD): to do so, go to the Active Directory tab in the Azure Portal, click on the Applications tab, and then the Add button. After filling-in the quick wizard, go to the app Configure tab and add 3 Delegated Permissions to ‘Power BI Service’: View users Groups, View all Reports, and View all Dashboards. Also take a quick look at the page URL: the first GUID is your Tenant ID and the second is your Client ID. Write them down, they will be needed later.


JavaScript code running in the browser cannot be trusted, so authentication cannot rely on API keys and the OAuth2 Implicit Flow needs to be used instead. There is no UI to enable that: the AAD JSON manifest needs to be downloaded, updated, and uploaded by clicking on the Manage Manifest menu.

AAD Manifest

In the JSON file look for the oauth2AllowImplicitFlow property and set it to true.

Project setup

Any IDE and web server can be used to write and run the code. I used Visual Studio 2015 which quickly creates a no-frills website using the ‘File > Open > Web Site’ menu and starts an IIS Express web server when hitting F5. It also comes with Bower pre-installed, which simplifies package management. To get started open a command prompt and run:

bower init
bower install <package> -save

where <package> is:

adal-angular handles AAD auth in AngularJS modules
angular Web App framework
angular-route UI URL routing (required by ADAL Angular)
bootstrap style
fontawesome icons
require-css loads CSS files
requirejs module loader
requirejs-domready delays running the RequireJS callback until the DOM is ready

Web App

The full code is available in this GitHub repo and a few points of interest are highlighted below.

The code relies on ADAL.JS to retrieve access tokens from AAD and to attach them as HTTP headers (aka Bearer tokens) during REST calls. ADAL.JS needs to be given the Tenant and Client IDs written down earlier. The Power BI REST endpoint also needs to be added and white-listed to enable authenticated CORS REST calls.

    tenant: "72f988bf-86f1-41af-91ab-2d7cd011db47", //
    clientId: "92f12926-5cf0-4460-83b6-14366bbaa88a", // Power BI AngularJS SPA
    endpoints: {
        "": "",
    requireADLogin: true,
    cacheLocation: 'localStorage'


The Power BI REST APIs can then be called to get a list of reports, along with their associated embedding URLs:

$http.get('')).then(function (response) {
    $scope.reports =;
    $scope.selectedReport = $scope.reports[0].embedUrl;

An iframe receives those URLs via AngularJS scopes:

<iframe id="report" ng-show="selectedReport" src="{ {selectedReport} }" frameborder="0" seamless style="height: 400px;" class="col-sm-12"></iframe>

and when the iframe is done loading the report, the AAD access token is sent to Power BI via an iframe message:

var iframe = document.getElementById("report");
iframe.addEventListener("load", function () {
    var token = adal.getCachedToken("");
    iframe.contentWindow.postMessage(JSON.stringify({ action: "loadReport", accessToken: token }), "*");
