In express 4.x:

req.get('Referrer')

This will also check both spellings of referrer so you do not have to do:

 req.headers.referrer || req.headers.referer

HTTP specs's header name is `Referer` and I find `req.get('Referrer')` and `req.get('Referer')` get the same result – CDT Jan 20 '22 at 02:16

If you mean how do you get it when running an express server, then it's done using the header method on your request:

req.headers.referer;
// => "http://google.com"

It should be `req.headers['referer']`. – Andrew_1510 May 02 '14 at 10:37

None of this works for me, I get `undefined`. This is in express router. – geoidesic Aug 26 '22 at 22:58
