One thing that I've been curious how to do in Svelte is include a components' HTML children in a place using svelte, like this:
<Popup> <h1>Hello World</h1> </Popup>
I've done some research, and I saw that rich harris was doing this with his svelte cubed framework.
You might want to learn more about the slot.
App.svelte
<script> import Popup from './lib/Popup.svelte'; </script> <Popup> <h1>Hello World</h1> </Popup>
Popup.svelte
<div> <slot> This is fallback content when no content is provided </slot> </div>
