Any way to use comments as anchor for components?

[shirotech]

i.e. currently I have something like this in my component.

<script>
  let ref;

  onMount(() => {
    const child = ref.nextElementSibling;
  });
</script>

<span bind:this={ref} style="display:none"></span><slot/>
<div>some content</div>

Was wondering if there is any easy way to access the dom element of a slot? If we need some kind of anchors, is it possible to use a comment or even a text node? Many thanks.

For default slots (and hopefully eventually for named slots) there isn't necessarily a single top-level DOM element associated with the slot. There's an open issue #2106 for providing an official way of seeing whether a slot has content, but I don't think there's been much discussion about what the exposed value would be, besides truthy vs falsy.

If you're asking for something like bind:this on comment nodes, that seems niche enough that it would be very low priority if it were accepted as a proposed feature.

+1 for this, getting a bind:this on comment nodes or possibly even text nodes would be really useful for page builders
