How to configure HTTPS with Lets Encrypt, Nginx reverse proxy, Express and Node

1. Have a Node app ready for production.
2. Create an app.js file in your project directory:

const express = require('express');
const path = require('path');
const app = express();

// Allow dotfiles - this is required for verification by Lets Encrypt's certbot

SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)

Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "your_email@example.com"

$ cat /etc/sysctl.conf
# General gigabit tuning:
net.core.rmem_max = 16777216
