Users will also expect us to provide a way to log out of our application. Passport makes this easy by adding a logout function to the request. We just need to make use of this in one of our routes here src/routes/index.js:
router.post('/logout', function(req, res){
req.logout();
res.redirect('/');
});We can add a log out button to our view to make use of this new route as in src/views/index.hjs:
{{#loggedIn}}
<form action="/logout" method="POST">
<input type="submit" value="Log out" />
</form>
