Nodes

You can use Svelte components in your markdown files, you can define Svelte Component for each node.

Create a Svelte file and export Svelte components with the same name as the node from the module context.

<!-- ./src/lib/Nodes.svelte -->
<script context="module">
    export { default as Heading } from './Heading.svelte';
</script>

// svelte.config.js
import { dirname, join } from 'path';
import { fileURLToPath } from 'url';

markdoc({
    nodes: join(dirname(fileURLToPath(import.meta.url)), './src/lib/Nodes.svelte'),
})

<!-- ./src/lib/Heading.svelte -->
<script>
    export let level;
</script>

<svelte:element this={`h${level}`}><slot /></svelte:element>

You can find a list of available nodes here.
