Node.js: Get client's IP

Question

req.connection.remoteAddress, req.headers[\'x-forwarded-for\'], req.ip, req.ips, what does it all mean?

Is there a straight forward way to simply get the IP address

Answer 1

req.ip is the straightforward way to get the client's IP address in Express. You can see the logic it uses (which involves grabbing the first item from the array of proxy addresses req.ips, where that array is constructed from the x-forwarded-for headers) here.
