This article will show you how to integrate Okta login capabilities into an AngularJS application. I couldn’t find any information on how to use angularjs 1.6 to develop an okta authentication app.
The okta stated that they did not support angularjs app, You need to use VanillaJS to add support with okta.
What is Okta?
Okta is a cloud service that allows developers to create, edit, and securely store user accounts and data, as well as connect them to one or more apps. You can use our API to do the following:
- Authenticate and authorize your users
- Store data about your users
- Perform password-based and social login
- Secure your application with multi-factor authentication
What’s Okta JavaScript SDK
Auth.js is a library wrapper for the Okta Authentication API. Use it when you need complete control of your sign in experience, or use the Okta Sign-In Widget for a pre-built, customizable experience
The Pre-Requisites:
- A angularjs/Java-script app
- Register for a free developer account for Okta
- You need to download Okta Auth JavaScript SDK
Create Angularjs applicationApp
Let’s create an angular js application, I have created a hello-ang/ app folder into the workspace.
cd > hello-ang/
Created an index.html file into the root of the folder, This file will include all CSS and js files. I also added the CDN file path of the okta auth SDK file.

Create a main.js file and paste the below code into his folder:
/**
* Main AngularJS Web Application
*/
var app = angular.module('phpflowApp', [
'ngRoute'
]);
/**
* Configure the Routes
*/
app.config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {
$routeProvider
// Home
.when("/", {templateUrl: "partials/home.html", controller: "PageCtrl"})
// else 404
.otherwise("/404", {templateUrl: "partials/404.html", controller: "PageCtrl"});
$locationProvider.html5Mode(true);
}]);
/**
* Controls Pages
*/
app.controller('PageCtrl', function ( $scope) {
var config = {
// Required config
issuer: 'https://xxxx/oauth2/default',
// Required for login flow using getWithRedirect()
clientId: 'xxxx',
redirectUri: 'http://localhost:8080/',
responseType: 'code',
devMode: true
};
$scope.username = '';
var authClient = new OktaAuth(config);
authClient.start();
let signin = async function() {
if (authClient.isLoginRedirect()) {
try {
await authClient.handleLoginRedirect();
} catch (e) {
// log or display error details
console.log('Exception - '+e);
}
} else if (!await authClient.isAuthenticated()) {
// Start the browser based oidc flow, then parse tokens from the redirect callback url
console.log('signInWithRedirect - ');
authClient.signInWithRedirect();
} else {
// User is authenticated
console.log('authenticated - ');
Promise.all([
authClient.tokenManager.get('idToken')
])
.then(([idTokenObject]) => {
localStorage.setItem("username", idTokenObject['claims']['name']);
$scope.username = localStorage.getItem("username");
console.log($scope.username);
//return authClient.token.getUserInfo(accessTokenObject, idTokenObject);
});
}
}
signin();
console.log($scope.username);
$scope.logout = function() {
console.log('hellooo');
authClient.signOut();
}
});
install http-server package here for developement server:
$hello-ang> npm install -g http-server
Let’s create a partials/home.html file:
<div id="myCarousel" class="carousel slide">
<div class="section">
<div class="container">
<div class="row" ng-if="username == ''">
<h2>Hey, You need to sign-in</h2>
<a class="btn btn-primary" href="/">Login</a>
</div>
<div class="row" ng-if="username != ''">
<h2 class="page-header">Welcome User:<small style="background-color: yellow;">{{username}}</small></h2>
<a class="btn btn-primary" ng-click="logout()">Logout</a>
</div>
</div>
<!-- /.container -->
Create and Configure a New Okta applicationApp
Let’s Create a app into developer console. I assumed, You have developer account and logged in.
Navigate to Applications in the sidebar navbar and then click Create Application button.
Now select OpenID and SPA as the platform and click Next.
Enter app_name, sign-in and sign-out redirect UI.
Finally, ensure that Login redirect URIs contains http://localhost:8080 and click Done.
User Authentication Using Okta
Let’s walk you through adding user authentication to your angularjs or JavaScript application.
Get Okta App Details
Open app details page from okta developer dashboard, Copy okta client-id and okta domain name from here:
Configure Angularjs app
We will paste above details into main.js file:
var config = {
// Required config
issuer: 'https://oktadomain/oauth2/default',
// Required for login flow using getWithRedirect()
clientId: 'client-id',
redirectUri: 'http://localhost:8080/',
responseType: 'code',
devMode: true
};
Replace oktadomain and client-id with your app details.
Start app
$hello-ang>http-server -o
Your HTTP server should startup. Open a browser and navigate to http://localhost:8080.
You will get the below page:
