How to write a service worker with Astro.build

Astro.build is a web framework for building websites, and it also enables you to create Progressive Web Apps (PWAs). One of Astro's powerful features is its ability to import and compile scripts at runtime.

<script>

</script>

In this example, we utilize the <script> tag to import a local file ("../scripts/script.js"). Astro compiles this file and makes it available for use in the browser.

You can leverage this feature to declare a Service Worker file. However, instead of using import(path), you should use import.meta.resolve(path). You should also register the service worker with ServiceWorkerContainer.register, like so:
