Web Development Programming Tutorials, Guides & Best Practices

To ensure Apache starts on boot, use the following command:

sudo systemctl enable apache2

Once Certbot is installed, you can generate the SSL certificate for your domain. Certbot automatically obtains the certificate and configures your web server to use it.

Run the following command to obtain and automatically configure your Apache server to use the SSL certificate:

// Listen for push events
self.addEventListener('push', event => {
  const data = event.data.json();
  self.registration.showNotification(data.title, {
    body: data.body,
    icon: 'images/icon-192x192.png'
  });
});

Note: Actual push functionality requires a server-side setup using libraries like web-push in Node.js.
