Angularjs- Azure Active Directory B2C using Hello.js

Web app implementation uses Hello.js that performs identity management with Azure AD B2C . Hello.js is a client-side JavaScript SDK for authenticating with OAuth2 web services and querying REST APIs.
jwtHelper of angular-jwt will take care of helping you decode the token (JWT) and check its expiration date. JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.
Find the angularjs example below
Let us have a LoginController

.controller('LoginController', function($scope, $state, $ionicPopup, jwtHelper,  HelloService) {

    // Initialize
    (function initialize() {
            HelloService.initialize().then(function(authResponse) {
            displayUserDetails(getUserData(authResponse));
        });
    })();

    $scope.login = HelloService.login;
    $scope.logout = HelloService.logout;


    // Decode decode the token and display the user details
    function getUserData(response) {
        var user = {};
        user.token = response.access_token || response.token;
        var data = jwtHelper.decodeToken(user.token);
        user.expires_in = new Date(response.expires * 1000) || response.expiresOn;
        user.name = data.name;
        user.email = data.emails ? data.emails[0] : '';
        user.id = data.oid;
        return user;
    };

    function displayUserDetails(user) {
        $scope.user = user;
        $ionicPopup.alert({
            title: user.name,
            template: '<b>Email:</b> ' + user.email + '<br> <b>Id:</b> <code>' + user.id + '</code>'
        });
    }
});

Enter the Azure AD B2C settings here

.value('settings', {
    // ADAL-B2C configuration
    adalB2C: {
        tenantName: 'Enter your tenant name',
        clientId: 'Enter your client id',
        policy: 'Enter your policy name'
    }
});

And here is the hello.service that implements Azure AD B2C using Hello.js

.service('HelloService', function(hello, $q, settings) {

    var network = 'adB2CSignInSignUp';

    this.initialize = function() {
        //initiate all policies
        hello.init({
            adB2CSignIn: settings.adalB2C.clientId,
            adB2CSignInSignUp: settings.adalB2C.clientId,
            adB2CEditProfile: settings.adalB2C.clientId
        }, {
            redirect_uri: '../',
            scope: 'openid ' + settings.adalB2C.clientId,
            response_type: 'token id_token'
        });
        var adB2CSignInSignUpPolicy = getPolicyConfiguredData();
        hello.init(adB2CSignInSignUpPolicy);
        var authResponse = hello(network).getAuthResponse();
        if (authResponse && !authResponse.error) {
            return $q.when(authResponse);
        } else {

        }
    };

    this.login = function() {
