angularjs - Lose cookie/session when reload page -

i have 2 separate applications:

1. angularjs client working on http://localhost:8080
2. nodejs api server working on http://localhost:3000

nodejs api server gives json data client (and not give html pages).

i store information autentificated user in sessionstorage.

the problem: when login system , reload page, lost information user in sessionstorage.

here angularjs auth service:

module.exports = function($http, $location, $cookies, $alert, $window) {   $window.sessionstorage.setitem('currentuser',      json.stringify($cookies.get('user')));   $cookies.remove('user');    return {    login: function(user) {      return $http.post('http://localhost:3000/api/login', user).success(function(data) {       $window.sessionstorage.setitem('currentuser', json.stringify(data));       $location.path('/fillprofile');        $alert({         title: 'cheers!',         content: 'you have logged in.',         placement: 'top-right',         type: 'success',         duration: 3       });     }).error(function() {         $alert({           title: 'error!',           content: 'invalid username or password.',           placement: 'top-right',           type: 'danger',           duration: 3         });       });   },   signup: function(user) {     return $http.post('http://localhost:3000/api/signup', user).success(function(data) {       $location.path('/login');        $alert({         title: 'congratulations!',         content: 'your account has been created.',         placement: 'top-right',         type: 'success',         duration: 3       });     }).error(function(response) {         $alert({           title: 'error!',           content: response.data,           placement: 'top-right',           type: 'danger',           duration: 3         });       });   },   logout: function() {     return $http.get('http://localhost:3000/api/logout').success(function() {       $window.sessionstorage.setitem('currentuser', null);       $cookies.remove('user');       $location.path('/login');        $alert({         content: 'you have been logged out.',         placement: 'top-right',         type: 'info',         duration: 3       });     });   } }; }; 

nodejs api

app.use(function(req, res, next) {   if (req.user) {     res.cookie('user', json.stringify(req.user));   }   next(); });  function ensureauthenticated(req, res, next) {   if (req.isauthenticated()) next();   else res.send(401); }  passport.serializeuser(function(user, done) {   done(null, user.id); });  passport.deserializeuser(function(id, done) {   user.findbyid(id, function(err, user) {     done(err, user);   }); });  passport.use(new localstrategy(function(username, password, done) {   user.findone({ username: username }, function(err, user) {     if (err) return done(err);     if (!user) return done(null, false);     user.comparepassword(password, function(err, ismatch) {       if (err) return done(err);       if (ismatch) return done(null, user);       return done(null, false);     });   }); })); 

routes

app.post('/api/login', passport.authenticate('local'), function(req, res) {   res.cookie('user', json.stringify(req.user));   res.send(req.user); });  app.post('/api/signup', function(req, res, next) {   var user = new user({     username: req.body.username,     email: req.body.email,     password: req.body.password   });   user.save(function(err) {     if (err) return next(err);     res.send(200);   }); });  app.get('/api/logout', function(req, res, next) {   req.logout();   res.send(200); }); 

try removing $cookies.remove('user'); on line 3
