Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

I will be using the root user, but would suggest creating a new user

$ mkdir test

$ cd test

This guide shows how to set up a bidirectional client/server authentication for plain TLS sockets.

Generate a Certificate Authority:

openssl req -new -x509 -days 9999 -keyout ca-key.pem -out ca-crt.pem

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

	//events - a super-basic Javascript (publish subscribe) pattern

	var events = {
