Very simple unsecure self-signed HTTPS to HTTP nodejs proxy

https2http_proxy.js

var httpProxy = require('http-proxy');
var pem = require('pem');

pem.createCertificate({ days: 1, selfSigned: true }, function (err, keys) {
  var httpsOptions = {
    key: keys.serviceKey,
    cert: keys.certificate
  };

  httpProxy.createServer({
    target: {
      host: '0.0.0.0',
      port: 3000
    },
    ssl: httpsOptions
  }).listen(4000);
});
