nginx how to get the request client ipaddress

I have ngnix proxying to a nodejs server. I am trying to read the request client ip address/host name in my nodejs, but it’s always


But in my nginx access log, I can see the client ip address printed, not sure why my nodejs server can’t get it.

x.x.x.x - - [24/Aug/2017:14:28:01 -0700] "GET ...."
