How to use node-http-proxy for HTTP to HTTPS routing?

Here's the module version that I'm using:

$ npm list -g | grep proxy
├─┬ http-proxy@0.10.0

A webservice calls into my machine and my task is to proxy the request to a different url and host with an additional query parameter based on the contents of the request's body:

var http      = require('http'),
    httpProxy = require('http-proxy')
    form2json = require('form2json');

httpProxy.createServer(function (req, res, proxy) {
  // my custom logic
  var fullBody = '';
  req.on('data', function(chunk) {
      // append the current chunk of data to the fullBody variable
      fullBody += chunk.toString();
  });
  req.on('end', function() {
      var jsonBody = form2json.decode(fullBody);
      var payload = JSON.parse(jsonBody.payload);
      req.url = '/my_couch_db/_design/ddoc_name/_update/my_handler?id="' + payload.id + '"';

      // standard proxy stuff
      proxy.proxyRequest(req, res, {
        changeOrigin: true,
        host: 'my.cloudant.com',
        port: 443,
        https: true
      });
  });
}).listen(8080);

But I keep running into errors like: An error has occurred: {"code":"ECONNRESET"}

Anyone have an idea about what needs to be fixed here?

This did the trick for me:

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

var options = {
  changeOrigin: true,
  target: {
      https: true
  }
}

httpProxy.createServer(443, 'www.google.com', options).listen(8001);

An "official" example from node-http-proxy (taken from: https://github.com/nodejitsu/node-http-proxy/blob/master/examples/http/proxy-http-to-https.js) 

var https = require('https'),
http  = require('http'),
util  = require('util'),
path  = require('path'),
fs    = require('fs'),
colors = require('colors'),
httpProxy = require('../../lib/http-proxy');

//
// Create a HTTP Proxy server with a HTTPS target
//
httpProxy.createProxyServer({
  target: 'https://google.com',
  agent  : https.globalAgent,
  headers: {
    host: 'google.com'
  }
}).listen(8011);
