simple node.js proxy. Allowing to tear down and bring up as needed. Usage: node proxy.js <from port> <to port>. Forever recommended.

proxy.js

let from = 80;
let to = 8080;
const httpProxy = require('http-proxy');

if(process.argv.length != 4){
	console.log('Did not supply from/to params, remapping ' + from + ' to ' + to);
}
else{
	from = Number(process.argv[2]);
	to = Number(process.argv[3]);
}

const proxy = httpProxy.createProxyServer({target:'http://localhost:'+to}).listen(from);

console.log('Proxy running from ' + from + ' to ' + to);
