Express redirect to front-end route with path

Let's say I have a SPA that has a route /contact

For the direct requests to Express (ie. not to index.html) I need to execute a redirect.

In Express I can define this route like this:

app.use(function(req,res,next) {
    if (req.path === "/contact" ) {
        return res.redirect("/?path=" + req.path);
    }
    next();
});

This means that if the user makes a direct request they will end up on index.html with "http://ift.tt/1xZhAbP" in their address bar. Then the front-end can take care of the routing etc.

But maybe there is a way to do this so the user does not see this ugly url?
