获取没有express.js的域名

Question

I have a MEAN app which responds to multiple domains. Domains are pointed to same IP and port.

Is there a way to get domain name from client request, without express.js?

So that I can load different database based on request domain name. I tried using process.domain and os.hostname which does not work on Windows OS (not sure about other OS).
