angular html5 mode allow file types with node

I have an angular app in html5 mode, and a node.js express back-end using the following snippet I can redirect everything back to the route:

app.use('/*', function(req, res){
    res.sendFile(__dirname + '/public/index.html');
});

But because of this my ng-include will no longer work:

ng-include="'app/img/svg/star.svg'"

How can I allow certain file types that say end in '.svg' to still be loaded?
