How can I render xml/rss in expressjs 4.x?

Question

I am creating a route to handle RSS feeds using the rss npm module.

I've generated the appropriate xml string, I just need to know how to output xml/rss using proper headers with express 4.0.

I tried this but it doesn't work, I get an empty json object:

res.xml(xml);

Figured it out:

res.set('Content-Type', 'application/rss+xml');
res.send(xml);
