passport.js , after authentication in popup window, close it and redirect the parent window

Question

In my node.js express app, I integrated the Facebook authentication using passport.js . I can open the Facebook login page in a popup window, then the login takes place. At this stage, the redirection takes place in the popup window . But I need to close the popup window and to make the redirection in the parent window (i.e. the parent window will redirect). I am gonna paste the full code here although I think the main issue is in the template file(.ejs).

And I could not find any solution in the similar questions out there in SO.

// Passport session setup.
passport.serializeUser(function(user, done) {
  done(null, user);
});

passport.deserializeUser(function(obj, done) {
  done(null, obj);
});


// Use the FacebookStrategy within Passport.
passport.use(new FacebookStrategy({
    clientID: config.facebook_api_key,
    clientSecret:config.facebook_api_secret ,
    callbackURL: config.callback_url
  },

  function(accessToken, refreshToken, profile, done) {

    console.log(" id = "+profile.id);

    process.nextTick(function () {
      //Check whether the User exists or not using profile.id
      //Further DB code.
      profile.user_id="00000444000555";
      return done(null, profile);
    });

  }
));

app.set('views', __dirname + '/views');

app.set('view engine', 'ejs');
//app.set('view engine', 'jade');
app.use(cookieParser());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(session({ secret: 'keyboard cat', key: 'sid'}));
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(__dirname + '/public'));

//Router code
app.get('/', function(req, res){
  res.render('index', { user: req.user });
});

app.get('/account', ensureAuthenticated, function(req, res){

    console.log(req.user);
  res.render('account', { user: req.user });
});

//Passport Router
app.get('/auth/facebook', passport.authenticate('facebook'));
app.get('/auth/facebook/callback',

passport.authenticate('facebook', {
       successRedirect : '/',
       failureRedirect: '/login'
  }),

   function(req, res) {
    res.redirect('/');

  });

app.get('/logout', function(req, res){
  req.logout();
   res.redirect('/');
});

function ensureAuthenticated(req, res, next) {
     if (req.isAuthenticated()) { return next(); }
  res.redirect('/login')
}
app.listen(8000);

And the template file is :

<script type="text/javascript">
    if (window.location.hash && window.location.hash == '#_=_') {
        if (window.history && history.pushState) {
            window.history.pushState("", document.title, window.location.pathname);
        } else {
            // Prevent scrolling by storing the page's current scroll offset
            var scroll = {
                top: document.body.scrollTop,
                left: document.body.scrollLeft
            };
            window.location.hash = '';
            // Restore the scroll offset, should be flicker free
            document.body.scrollTop = scroll.top;
            document.body.scrollLeft = scroll.left;
        }
    }
</script>

<% if (!user) { %>

  <div style="width:500px;height:180px;">
    <h2 style="font-size:40px;">Welcome! Please log in.</h2>
    <a href="javascript:void(0)" onclick=" window.open('/auth/facebook','',' scrollbars=yes,menubar=no,width=500, resizable=yes,toolbar=no,location=no,status=no')"><img src="fb-login.jpg" width="151" height="24"></a>
    </div>

<% } else { %>

<script type="text/javascript">

    window.parent.location.href ="/";
    window.close();
</script>
    <h2>Hello, <%= user.displayName %>.</h2>
<% } %>

Answer 1

The simplest solution is this:

res.send('<script>window.close()</script>');
