passportjs stuck at res.isAuthenticated()

I am new to Angularjs and also Javascript..

I am implementing passport authentication in my Angularjs project.... registration and login is working.....

But after logging in or routing to any other views or states, I am checking whether the user is authenticated...but the function that triggers to check whether the user is valid is stuck at executing query like the following:

<pre><code>

var checkLoggedin=function($q, $timeout, $http, $location, $rootScope){
debugger;

// Initialize a new promise
var deferred = $q.defer();

// Make an AJAX call to check if the user is logged in
  $http.get('/loggedin').success(function(user){
    debugger;
    // Authenticated
    if (user !== '0')
        deferred.resolve();

    // Not Authenticated
    else {
        $rootScope.message = 'You need to log in.';
        deferred.reject();
        $location.url('/login');
    }
  });
  return deferred.promise;
 };

</code></pre>

But when it calls $http.get('/loggedin') in the console I would get:

     serializing user:26
     POST /login 200 413.520 ms - 164
     Executing (default): SELECT "usid" AS "id", "usname" AS "username",                                                                                                                                                     "uspassword" AS "password", "usemail" AS "email" FROM "dbuser" AS "User" LIMIT 1;

and it will be stuck there and in my ui-state config I have
<pre><code>
    .state('dashboard', {
            url: "/dashboard",
            templateUrl: 'Dashboard/View/dashboard.html',
            controller:'DashboardController',
            resolve: {
                loggedin:checkLoggedin
            }
        })
</code></pre>

so my state waiting for the checkloggedin to be resolved...but its stuck there nothing response I am getting...Is there any way I verify the user is logged in....I searched but couldn't find a way its very trickier.....hope some one has faced same problem....

I have implemented serialize and deserialize as follows

<pre><code>
     module.exports = function(passport){
        passport.serializeUser(function(user, done) {
        console.log('serializing user:'+user.id);
        done(null,user.id);
    });

    passport.deserializeUser(function(id, done) {
        var collection = User;
        collection.findOne({'_id' :  id },function(err, user) {
            console.log('deserializing user:',user);
            done(err, user);
        });

    });

    login(passport);
    signup(passport);

   }
</code></pre>
