Part 3 / Special elements / <svelte:self>
Svelte provides a variety of built-in elements. The first, <svelte:self>
, allows a component to contain itself recursively.
It's useful for things like this folder tree view, where folders can contain other folders. In Folder.svelte
we want to be able to do this...
{#if file.files}
<Folder {...file}/>
{:else}
<File {...file}/>
{/if}
...but that's impossible, because a module can't import itself. Instead, we use <svelte:self>
:
{#if file.files}
<svelte:self {...file}/>
{:else}
<File {...file}/>
{/if}
