The data Prop
The page receives a special data prop populated from the load function return.
<!-- +page.svelte -->
<script>
export let data;
</script>
<ul>{#each data.items as it}<li>{it.name}</li>{/each}</ul>Type Safe
With TypeScript, SvelteKit generates types from load to data automatically.
<script lang="ts">
import type { PageData } from "./$types";
export let data: PageData;
</script>Multiple Properties
Return multiple keys; access each via data.key.
Reactivity
The data prop updates reactively on navigation. Bindings re-render.
$page Store
Access metadata anywhere via $page from $app/stores.
import { page } from "$app/stores";
<p>Current path: {$page.url.pathname}</p>Layout Data Merging
Layout load and page load merge into one data object accessible everywhere in the page tree.
Custom Props
You can pass any serializable values: arrays, objects, primitives, even Promises (for streaming).
Avoid Functions
Functions cannot be serialized; return only data, not behavior.
Defaults
If load returns nothing, data is {}.
Composing With Stores
You can populate stores from load data on mount for global access.
Page Errors
If load throws, the closest +error.svelte shows. data is not set.
