How to make a redirect (301) in Node.js / Express?

Question

I have a static site, a simple single page layout that I deploy in Dokku. I need to make a redirect (301) from www to non www and from *.website1.com to w

To anyone arriving here from Google, while @frederic's answer is still what is recommended by the express docs, the response.send(status, body) style has been deprecated and will generate a warning (I am on express 4.13.4 at time of writing), and more importantly I found that it no longer produced the desired result when redirecting.

As @Markasoftware mentioned, to achieve an automatically followed 301, you need to set the location header to the url you want. The request body can be empty:

   response.set('location', 'https://my.redirect.location');
   response.status(301).send()
