Set up Let's Encrypt with Nginx and Node

This guide to install SSL cert on Nginx as a reverse proxy, and forward the request to a node app

Install certbot

https://www.nginx.com/blog/using-free-ssltls-certificates-from-lets-encrypt-with-nginx/

$ apt-get update
$ sudo apt-get install certbot
$ apt-get install python-certbot-nginx

Add the domain to Nginx conf

$ sudo vim /etc/nginx/sites-enabled/default

Inside of default conf file add the following to redirect the domain to the localhost port 4444

server {
    listen 80;
    server_name myserver.com;
    
    location / {                                                   
        proxy_pass http://127.0.0.1:4444;                      
        proxy_http_version 1.1;                                        
        proxy_set_header Upgrade $http_upgrade;                        
        proxy_set_header Connection 'upgrade';                         
        proxy_set_header Host $host;                                   
        proxy_set_header X-Forwarded-Proto https;                      
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;   
   }                                                              
}

Install http-server to serve the static folder ~/www for verification by Let's encrypt

$ npm i -g http-server
$ http-server -p 4444 ./www

Request the SSL cert and configure Nginx at the same time

$ sudo certbot --nginx -w ./www -d myserver.com

the -w param tells certbot where the static folder is to add a file to response to its verification
