Simple retro guestbook app with steps how to deploy it to production server with automatic TLS (HTTPS).

npm run dev

Create a new server with a provider such as:

• Linode/Akamai
• Digital Ocean
• Hetzner
• etc.

What do we need to install?

• Git (to clone the repository)
• Node.js (runtime)
• Caddy (web server with automatic TLS)

Use NodeSource to install Node.js.

• https://github.com/nodesource/distributions#installation-instructions

After test if it works:

node --version

cd /opt
git clone https://github.com/rostislavjadavan/guestbook-app
cd guestbook-app
npm install

Note: Don't forget to create .env file with database credentials.

For process management we will use PM2 (https://pm2.keymetrics.io/docs/usage/quick-start/).

To make application persistent we need to:

# Generate startup script
npm run pm2:init

# Start the application
npm run pm2:start

# Save the process list
npm run pm2:save

More information: https://pm2.keymetrics.io/docs/usage/startup/

https://caddyserver.com/

• https://caddyserver.com/docs/install#debian-ubuntu-raspbian

Edit /etc/caddy/Caddyfile:

example.com {
    tls email@example.com

    reverse_proxy localhost:3000
}

To check for errors you can use caddy validate command.

Note: Replace example.com with your actual domain name and [email protected] with your email address. Your email address will be used as a contact for the certificate provider, Let's Encrypt (https://letsencrypt.org/).

Don't forget to restart Caddy after editing the config file:

systemctl restart caddy

After restart it should automatically obtain TLS certificate and serve the application. If not check the logs via journalctl -u caddy.

Create new database at https://neon.tech/

CREATE TABLE messages (
    id SERIAL PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    message TEXT NOT NULL,
    timestamp TIMESTAMP DEFAULT current_timestamp
);
