UPNP Port Forwarding for node.js
View upnp.js

This is a simple way to forward ports on NAT routers with UPNP.
This is a not-for-production hack that I found useful when testing apps
on my home network behind ny NAT router.

server, but for some reason omit a client connecting to it. I added an
example at the bottom.
Save the following server in example.js:
var net = require('net');

TLS client & server in NodeJS

1. Overview

This is an example of using module tls in NodeJS to create a client securely connecting to a TLS server.

It is a modified version from documentation about TLS, in which:

  • The server is a simple echo one. Clients connect to it, get the same thing back if they send anything to the server.
  • The server is a TLS-based server.
  • Clients somehow get the server's public key and use it to work securely with the server
