Package description

What is forwarded?

The 'forwarded' npm package is designed to parse the 'X-Forwarded-For' header from an HTTP request, which is a standard header for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. This package extracts the IP addresses listed in the header and provides them in an array format, making it easier to handle cases where there are multiple proxies in use.

What are forwarded's main functionalities?

Parse X-Forwarded-For header

This feature allows you to parse the 'X-Forwarded-For' header from an HTTP request object and returns an array of IP addresses that were added by each proxy.

const forwarded = require('forwarded');
const req = { headers: { 'x-forwarded-for': '192.0.2.60, 198.51.100.17' } };
const ips = forwarded(req);
console.log(ips); // ['192.0.2.60', '198.51.100.17']
