@prismicio/svelte is the official Prismic package for creating web apps with Prismic and Svelte.
To learn to develop with Prismic and Svelte, see our user-friendly Svelte guide.
npm install --save-dev @prismicio/svelteHere is an example in a Svelte project. The App.svelte file will import the SliceZone and use it to render Slices as Svelte components.
<script>
import * as prismic from '@prismicio/client'
import { SliceZone } from '@prismicio/svelte'
// Import Slices components and map them to API IDs
import ExampleSlice from './slices/ExampleSlice.svelte'
const components = {
'example_slice_a': ExampleSlice,
}
// Query a document from Prismic
const client = prismic.createClient('example-prismic-repo')
const promise = client.getFirst()
</script>
{#await promise}
<p>Loading Slices</p>
{:then document}
<SliceZone
slices={document.data.body}
{components}
/>
{:catch error}
<pre>{JSON.stringify(error.message, null, 2)}</pre>
{/await}Each Slice component receives a slice object as a prop.
<script>
export let slice
</script>
<h1>{slice.primary.example_key_text_in_slice}</h1>@prismicio/svelte exports the following components to render content from the Prismic API.
<script>
import { SliceZone } from '@prismicio/svelte'
import { ExampleSliceA, ExampleSliceB } from '$lib/slices'
export let data
</script>
<SliceZone
slices={data.document.data.body}
components={{
example_slice_a: ExampleSliceA,
example_slice_b: ExampleSliceB
}}
context={{ foo: 'bar' }}
/>The SliceZone is a Svelte component that renders an array of Prismic Slices with corresponding Slice components.
The SliceZone accepts five props:
