Heroku terminates SSL connections at the load balancer level, so req.secure will never be true, because your connection to heroku's load balancer is not using SSL, thus creating an infinite redirect loop.

You have to check the X-Forwarded-Proto header instead:

if(req.headers["x-forwarded-proto"] === "https"){
  // OK, continue
  return next();
};
res.redirect('https://'+req.hostname+req.url);

Edit: you can also set app.enable("trust proxy") to have express check the headers automatically. See http://expressjs.com/guide/behind-proxies.html
