Default Snippet
Content placed inside a component's tags becomes the default snippet, accessible via children.
<Card>
<p>Inside the card</p>
</Card>In the Component
Render the default content with the children prop.
let { children } = $props();
<div class="card">
{@render children()}
</div>Named Snippets
Pass multiple snippets by name as props.
<Card>
{#snippet header()}<h2>Title</h2>{/snippet}
{#snippet body()}<p>Text</p>{/snippet}
</Card>Receive Named
Declare each named snippet as a prop.
let { header, body } = $props();
{@render header()}
{@render body()}Fallbacks
Default fallback content using normal conditionals.
{#if header}{@render header()}{:else}<h2>Default</h2>{/if}Type Safety
Type each snippet param explicitly for IDE support.
Replacing Named Slots
Snippets replace the named slots pattern from Svelte 4, with more power.
Default Content
Snippets do not have built-in fallback; use {#if} for that.
Composition Patterns
Combine default and named snippets for headless component designs.
Migration Tip
When migrating, convert each named slot to a named snippet prop.
TS Inference
Svelte 5 generates Snippet types automatically from your component's props.

Recap
Default content uses the children snippet; named snippets are explicit props rendered with @render.
