You need to export a custom capture and restore object, similar to this, and then bind it to the component, so the component can modify it.
from sveltekit-superforms.
I ended up doing this:
<!-- MyForm.svelte -->
<script lang="ts">
import type { Snapshot } from '@sveltejs/kit';
import { superForm, type SuperValidated, type Infer } from 'sveltekit-superforms/client';
import { schema } from './schema';
export let data: SuperValidated<Infer<typeof schema>>;
export let snapshot: Snapshot;
const form = superForm(data, {
SPA: true,
validators: zod(schema),
...
});
const { form: formData, capture, restore, enhance } = form;
snapshot = { capture, restore }
</script>
<form use:enhance method="POST">
<!-- form fields here -->
</form>
<!-- +page.svelte -->
<script lang="ts">
import type { Snapshot } from '@sveltejs/kit';
import MyForm from './MyForm.svelte'
export let data;
export let snapshot: Snapshot = { capture() {}, restore(snapshot) {} };
</script>
<!-- not sure why this is needed, but it doesn't seem to work without it... -->
<svelte:options accessors />
<MyForm data={data.form} bind:snapshot />
Is that basically what you had in mind? I'm not sure if I need to be concerned about the accessors
thing, or why it's needed. I'm also a bit surprised that this works; I thought that the restore
function would run when the page component loaded, before the child <MyForm>
component had a chance to set it to something meaningful. It seems to work, but I don't know if this introduces a race condition or not.
