I'd like to render a 'current' class on each of my navigation links depending on which page I'm on in my layout.ejs template.

Currently, my express controller index looks like this:

// About

exports.about = function(req, res) {

    res.render('content/about.ejs', {

        title: 'About'

    });

};

And in my layout.ejs I have the following, which I'd like be rendered dynamically.

<ul class=nav id=nav>

    <li><a href=/>Home</a></li>

    <li class=current><a href=/about>About</a></li>

    <li><a href=/>Contact</a></li>

</ul>

Any ideas of how to achieve this?
