javascript - Firebase 3 Ionic Email Verification -

i working on ionic application uses firebase 3 baas. application trying implement email verification feature. firebase sending email email template want change url in email node server run "applyactioncode(oobcode)" , set emailverified property user in database true. problem cannot find way send uid if user in email.

here code in ionic -

register: function(formuser) {       var d = $q.defer();       auth.$createuserwithemailandpassword(formuser.email, formuser.password)         .then(function(user) {           $log.log("user created uid: " + user.uid);           auth.user = $firebaseobject(usersref.child(user.uid));           auth.user.id = user.uid;           auth.user.email = user.email;           auth.user.image = user.photourl;           auth.user.emailverified = user.emailverified;           auth.user.provider = user.providerid;           user.sendemailverification();           auth.user.$save().then(function(){             d.resolve();           }).catch(function(error){             console.log("from save "+error);             d.reject(error);           });         })         .catch(function(error) {           $log.log(error);           d.reject(error);         });         return d.promise;     }, 

this sends out email correctly url -

https://www.mynodeserver/verifyemail?mode=<mode>&oobcode=<code> 

this verify email function on node server -

router.get('/verifyemail', function(req, res){   console.log(req.query.oobcode);   var oobcode = req.query.oobcode;   var apikey = req.query.apikey;   var config = {     'serviceaccount': "serviceaccountcredentials.json",     'databaseurl': "https://myappdatabase.firebaseio.com"   };   var myapp = firebase.initializeapp(config);   var auth = myapp.auth();   auth.applyactioncode(oobcode).then(function(data){     console.log("after action"+data);     //set uses emailverified value true here      res.json("success!!");   }); }); 

currently getting auth.applyactioncode() not function. want way tell node server user id can update emailverified value user.
