Effortlessly passing request values to context in ExpressJS

During the migration process from Django to Express, I am simplifying by passing `req.user0` and `req.isAuth` values into the view as variables through context. Here is an example:

router.get('/', (req, res) => {
    res.render('index', {
        isAuth: req.isAuth, // check if user is auth.
        user: req.user      // get user's profile or False.
    })
});

While this method works, I have numerous routes and wish to avoid repetition. Is there a more efficient way to include these variables in my view (.pug file) without specifying them in each route?
