How can I build offline web apps?

To build offline web apps, you can use technologies like Service Workers and the Cache API. Would you like to know more about these?

Yes, what are Service Workers?

Service Workers are scripts that run in the background, separate from your web page, enabling features like offline capabilities and background sync.

How do I implement a Service Worker?

You can implement a Service Worker by registering it in your main JavaScript file and defining its behavior in a separate script.

Can you give me an example of a simple Service Worker?

Sure! Here's a basic example:

self.addEventListener('install', event => {
  event.waitUntil(
    caches.open('my-cache').then(cache => {
      return cache.addAll(['/index.html', '/styles.css']);
    })
  );
});

This caches your HTML and CSS files for offline use.
