🚀 Development

Start the local development server:

deno task dev
# or
npm run dev

Server runs at http://localhost:4321.

📦 Building for Production

Generate the static assets:

deno task build

The output will be in the ./dist folder.

🌍 Deployment & Nginx Setup

We use Nginx because it is an event-driven, asynchronous web server that is incredibly efficient at serving static files. For a static site like this, Nginx uses very little memory and can handle thousands of concurrent connections effortlessly compared to traditional process-based servers.

1. Build & Transfer

Run the build command and copy the ./dist folder to your server (e.g., /var/www/tech-blog).

2. Configure Nginx

On Debian/Ubuntu systems, Nginx uses a split configuration focus:

• /etc/nginx/sites-available/: Stores all your server block definition files (like tech-blog).
• /etc/nginx/sites-enabled/: Stores symlinks to the files in sites-available that you want to be active.

Step-by-Step Guide:

1. Create the configuration file: We name it tech-blog for clarity, but the name can be anything.

   sudo nano /etc/nginx/sites-available/tech-blog

2. Paste your configuration: Use the provided nginx.conf as a template. Update root to point to /var/www/tech-blog.

3. Enable the site: Create a symbolic link from sites-available to sites-enabled.

   sudo ln -s /etc/nginx/sites-available/tech-blog /etc/nginx/sites-enabled/

4. Test and Reload:

   sudo nginx -t   # Check for syntax errors
   sudo systemctl reload nginx

🔒 Security: Setting up HTTPS with Certbot

To enable HTTPS and get that "Green Padlock," we use Certbot from Let's Encrypt. It automatically handles the SSL certificate issuance and renewal.

1. Install Certbot and the Nginx Plugin

   Run these commands on your Debian VM:

   sudo apt update
   sudo apt install certbot python3-certbot-nginx -y

2. Obtain and Install the Certificate

   Certbot is smart enough to read your /etc/nginx/sites-available/tech-blog file, find your server_name, and configure the SSL for you.

   # Replace 'yourdomain.com' with your actual domain or free subdomain
   sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com

   During setup: It will ask for your email (for renewal alerts) and ask if you want to redirect all HTTP traffic to HTTPS. Choose "Yes" (Redirect).

3. Verify Automatic Renewal

   Let's Encrypt certificates expire every 90 days, but Certbot sets up a "timer" to renew them automatically. You can test this process with a "dry run":

   sudo certbot renew --dry-run
