Installation

npm install blocks-svelte-renderer

or

pnpm add blocks-svelte-renderer

or

yarn add blocks-svelte-renderer

Basic usage

<script lang="ts">
    import { BlocksRenderer } from 'blocks-svelte-renderer';

    const content = [ { type: 'paragraph', children: [{ type: 'text', text: 'Hello, World!' }] } ];
</script>

<BlocksRenderer {content} />

Custom components

You can override the default rendering by providing your own Svelte components for blocks and modifiers. Just pass what you want to customize—the rest uses the defaults.

<script lang="ts">
    import { BlocksRenderer } from 'blocks-svelte-renderer';
    import GreenBold from './GreenBold.svelte';
    import RedHeading from './RedHeading.svelte';

    const content = [ { type: 'paragraph', children: [{ type: 'text', text: 'Hello, World!' }] } ];
</script>

<BlocksRenderer
    content={data.dummydata}
    blocks={{ heading: RedHeading }}
    modifiers={{ bold: GreenBold }}
/>

(see /routes/+page.svelte for example)

Blocks are container elements that structure your content:

• paragraph
• heading
• quote
• code
• image
• list
• list-item

Modifiers are inline elements that style text:

• bold
• italic
• underline
• strikethrough
• code
• link

Pass your components via the blocks and modifiers props. Block components receive a node prop with the block data, while modifier components receive children that need to be rendered.
