Scittle in a service worker

You can use Scittle to bootstrap a ClojureScript based service worker.

Put the following code into e.g. scittle-sw.js to create a JavaScript based service worker, load Scittle, then fetch your script and eval it.

importScripts("scittle.min.js");

const request = await fetch("sw.cljs");
const text = await request.text();
const result = scittle.core.eval_string(text);

Then load scittle-sw.js in your HTML:

<script>
  if('serviceWorker' in navigator)
    navigator.serviceWorker.register('scittle-sw.js');
</script>

This will load sw.cljs and eval it in the context of the service worker.
