Proxy from Node.js to Heroku

I am trying to create a proxy from Node.js to Heroku using http-proxy. Everything works well locally, but I am having problems with Heroku.

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

settings = {
  "localhost": process.env.LOCALHOST,
  "devices":   process.env.DEVICES_URI
}

var options = { router: { } }
options.router[settings.localhost + '/devices']  = settings.devices + '/devices';

var port   = process.env.PORT || 8000;
var server = httpProxy.createServer(options).listen(port);

As you can see, in the example I set the routing object. I say the following: when the request matches "/ devices", then forward the request to the device service. (identified by DEVICES_URI environment var)

In development, I installed

  • LOCALHOST = 'localhost'
  • DEVICES_URI = 'http: // localhost: 3000'

This means that all requests sent to localhost: 8000 / devices are proxied to localhost: 3000 / devices that I want. Everything works perfectly.

The problem is in production. This gives me a timeout error repeating several times for each request.
