Node.js Deployment

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

1. Sign up for Digital Ocean

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

2. Create a droplet and log in via ssh

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

function toBaseN(num, base) {
  if (num === 0) {
    return '0';
  }
  var digits = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
  var len = Math.min(digits.length, base);
  var result = ''; 
  while (num > 0) {
    result = digits[num % len] + result;
    num = parseInt(num / len, 10);

# nginx:alpine contains NGINX_VERSION environment variable, like so:
# ENV NGINX_VERSION 1.15.0

# Our NCHAN version
ENV NCHAN_VERSION 1.1.15

# Download sources
RUN wget "http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz" -O nginx.tar.gz && \

Regular Event Loop

This shows the execution order given JavaScript's Call Stack, Event Loop, and any asynchronous APIs provided in the JS execution environment (in this example; Web APIs in a Browser environment)

Given the code

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];
