# - Nginx
# - Node
# - pm2
# - Certbot

> sudo apt-get install -y nodejs

# Clone the repo

# Lets encrypt - Free ssl domain
# Watch the next link and follow the steps 
# Will be working only on: ubuntu 18.04 + nginx 
# https://certbot.eff.org/lets-encrypt/ubuntubionic-nginx

# Use yarn to start the project, without sudo
> yarn install
> yarn run start
> yarn build

# Development environment if you wish.
> sudo yarn start 

# The command above run a script. 

# Now, use pm2 command to start a demon on that script
> pm2 start my-app/node_modules/react-scripts/scripts/start.js --name "my-app"

# If you want a reverse proxy using nginx (this is missing some good practices)
> sudo nano /etc/nginx/sites-available/default

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name ip; # Public ip v4 from the host

        listen 443 ssl; # managed by Certbot

        # RSA
        ssl_certificate /etc/letsencrypt/live/[subdomain.]domain.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/[subdomain.]domain.com/privkey.pem;

        include /etc/letsencrypt/options-ssl-nginx.conf;

    location / {
                
        proxy_pass http://localhost:port;
                
    }

}
