API Reference

BreadcrumbMeta

Each +page.svelte can export a breadcrumb constant of type BreadcrumbMeta. It's an async function that receives the current page and returns a {label, icon?} object.

Static label

Return a fixed string — the simplest pattern.

Dynamic from load data

Read the label from page.data populated by a layout or page load function.

Remote function

Call a server-side remote function inside the resolver — works with SSR and doesn't block hydration.

Optimistic update

Combine a query with a command and .withOverride() for instant client-side updates.

No breadcrumb

Omit the export entirely — the route is simply skipped in the breadcrumb trail.

Remote function breadcrumb

The label for this page is fetched server-side via a remote function — useful when the title isn't available in load data.
