Question

I\'ve been reading passport.js info and samples for two days, but I\'m not sure after that I did all the process of authenticating.

How do I know if I\

If you would like to use it in your templates as your code sample seems to indicate you can create some middleware such as this:

app.use(function (req, res, next) {
  res.locals.login = req.isAuthenticated();
  next();
});

Place that code somewhere after you have setup passport.

And then use it in your template (swig example)

{% if login %}
logout
{% else %} 
login
{% endif %}
