Email Verification after Sign Up

Syntax

  • Send email verification to logged in user's email address on file. Firebase allows you to customize what your email entails
  • When email hits user's email account, the user clicks on
  • Using your Router of choice (used angular-ui-router in above example), intercept parameters in the URL.
  • Chew the params using the applyCode function in Firebase.
  • See below for the functions involved in the above process.

Parameters

The Function...Does
sendEmailVerification()Sends a verification email to a user.
applyActionCode()Applies the action code which changes emailVerified from false to true

Remarks

The above pretty much sums up how to use the email verification scheme with Firebase. So far, it stands as one of the simplest ways to verify email I have seen.

There's a bit of an extended explanation of the above example available on Email Verification with Firebase 3.0 SDK.

Send-cum-Process Verification Action Code - AngularJS

// thecontroller.js
$scope.sendVerifyEmail = function() {
    console.log('Email sent, whaaaaam!');
    currentAuth.sendEmailVerification();
  }

// where currentAuth came from something like this:
// routerconfig

....
templateUrl: 'bla.html',
resolve: {
    currentAuth:['Auth', function(Auth) {
      return Auth.$requireSignIn() // this throws an AUTH_REQUIRED broadcast
    }]
  }
...

// intercept the broadcast like so if you want:

....

$rootScope.$on("$stateChangeError", function(event, toState, toParams, fromState, fromParams, error) {
      if (error === "AUTH_REQUIRED") {
        $state.go('login', { toWhere: toState });
       }
    });
....

// So user receives the email. How do you process the `oobCode` that returns?
// You may do something like this:

// catch the url with its mode and oobCode
.state('emailVerify', {
  url: '/verify-email?mode&oobCode',
  templateUrl: 'auth/verify-email.html',
  controller: 'emailVerifyController',
  resolve: {
    currentAuth:['Auth', function(Auth) {
      return Auth.$requireSignIn()
    }]
  }
})

// Then digest like so where each term is what they sound like:

.controller('emailVerifyController', ['$scope', '$stateParams', 'currentAuth', 'DatabaseRef',
  function($scope, $stateParams, currentAuth, DatabaseRef) {
    console.log(currentAuth);
    $scope.doVerify = function() {
      firebase.auth()
        .applyActionCode($stateParams.oobCode)
        .then(function(data) {
          // change emailVerified for logged in User
          toastr.success('Verification happened', 'Success!');
        })
        .catch(function(error) {
          $scope.error = error.message;
          toastr.error(error.message, error.reason, { timeOut: 0 });
        })
    };
  }
])
