301 Redirect with Express
If you've created a site using Node.js, there's a great chance you've used the Express framework. Express has turned into a massive project and for good reason: it's loaded with useful functionality, an easy API, and massive community support. On of my recent projects was using Express and I loved it!
One problem I recently needed to solve was creating a 301 redirect from an old staging domain to the new production domain. Here's how you can create that 301 redirect with Express:
app.use(function forceLiveDomain(req, res, next) {
// Don't allow user to hit Heroku now that we have a domain
var host = req.get('Host');
if (host === 'serviceworker-cookbook.herokuapp.com') {
return res.redirect(301, 'https://serviceworke.rs/' + req.originalUrl);
}
return next();
});
Surprisingly the redirect code is the first argument to redirect instead of the URL. It's important to call next() at the end of the function or a non-match will make your app hang!

Great code snippet and saved me a ton of time. Thanks!
You shouldn’t have the trailing slash after serviceworke.rs. I.e. instead of this:
It should be this:
Otherwise it redirects to:
