No boilerplate. No runtime shenanigans. Just Svelte, anywhere.

Quick Example

<!-- @custom-element my-counter shadow="open" template="lazy" -->
<script>
  let { count = 0 } = $props();
</script>

<button onclick={() => count++}>
  Clicked {count} times
</button>

Now just use it anywhere:

<my-counter count="5"></my-counter>
