user log in on page reload in MEAN app using passport.js

I'm using passportjs for authentication in my MEAN app.

I'm just confused about how can I identify that user is logged in or not on page refresh. Currently I'm storing user data in $rootScope, so it is working if I do not reload. But when I reload page $rootScope gets cleared so in this situation how can I get user information.

A cookie is set by passport, What is the purpose of that and can I use that cookie to authenticate, and if yes, how ?

You can setup a route /user and from angular check if a user is logged in

app.get('/user', function(req, res, next){
    if(req.user) return res.json(req.user);
    res.json({error: 'not logged in});
});

or inject user to page when you render it 

app.get('/', function(req, res, next){
    res.locals.user = req.user || null;
    res.render('index');
});

and in the view (i use handlebars)

<html>
  <head>
    <script>

    {{#if user}}
      var user = {
        username: {{user.name}},
        email: {{user.email}}
      }
    {{/if}}

    </script>
  </head>
  <body>

  </body>
</html>

and then in your controller check if the user object exists, inject $window as dependency

if($window.user) {
    $rootScope.user = $window.user;
}
