Storing information

You can use angular-storage to store the user profile and tokens so that they will not have to log in every time the page is refreshed.

In this tutorial, you'll learn how to do this.

1. Including angular-storage dependency

The first thing you should do is adding angular-storage and angular-jwt as dependencies. Follow this link to learn how to install angular-storage and this other one to install angular-jwt via npm, bower or manually. Once you've done that, just include angular-storage and angular-jwt modules to your application:

angular.module('myApp', ['auth0', 'angular-storage', 'angular-jwt']);

2. Saving the user information after login.

After the user has successfully signed in, you’ll want to store the profile details and authentication token:

function Controller(auth, $location, store, $scope)
  $scope.login = function() {
    auth.signin({}, function (profile, id_token, access_token, state, refresh_token) {
      store.set('profile', profile);
      store.set('token', id_token);
      $location.path('/');
    }, function () {
      // TODO Handle when login fails
    });
  }

3. Authenticating the user on page refresh

Now that you have the user information stored, you can use auth.authenticate method after the page has refreshed to let auth0-angular know that the user is already authenticated if the JWT isn't expired:

angular.module('myApp', ['auth0', 'angular-storage', 'angular-jwt'])
.run(function($rootScope, auth, store, jwtHelper) {
  // This events gets triggered on refresh or URL change
  $rootScope.$on('$locationChangeStart', function() {
    var token = store.get('token');
    if (token) {
      if (!jwtHelper.isTokenExpired(token)) {
        if (!auth.isAuthenticated) {
          auth.authenticate(store.get('profile'), token).then(function (profile) {

                    console.log("Logged in via refresh token and got profile");

                    console.log(profile);
                    
                    // Successful login, now redirect to secured content.

                }, function (err) { });;
        }
      } else {
        // Either show Login page or use the refresh token to get a new idToken
      }
    }
    
  });
});
