Show HN: Simple reverse proxy router in Node.js for multi tenant server

I am excited to share my latest creation: a powerful yet super simple Node.js reverse proxy server that forwards HTTP requests to a specified port based on the request host header / domain.

I use this for running multiple processes on a single server for different domains or subdomains. It supports "hot reload" by just editing the map object in the configuration file, and works great behind something like Cloudflare.
