@storyblok/richtext

@storyblok/richtext is a custom resolver for Storyblok rich text in JavaScript applications.

Installation

Add the package to a project by running this command in the terminal:

npm install @storyblok/richtext@latest

Usage

Basic

import { richTextResolver } from '@storyblok/richtext'; const { render } = richTextResolver(); const html = render(doc); document.querySelector<HTMLDivElement
  >('#app')!.innerHTML = `
  <div>${html}</div>
  `;
</HTMLDivElement>

Override resolvers

import { MarkTypes, richTextResolver } from '@storyblok/richtext'; const html = richTextResolver({ resolvers: { [MarkTypes.LINK]: (node) => { return `<button
  href="${node.attrs?.href}"
  target="${node.attrs?.target}"
>
  ${node.children}</button
>`; }, }, }).render(doc);

Resolvers context

You can access the resolver context via param when overriding a resolver. This give you access to:

• originalResolvers
• mergedResolvers (after the overrides)
• Internal render method

import { MarkTypes, richTextResolver } from '@storyblok/richtext';
const html = richTextResolver({
resolvers: {
   [BlockTypes.LIST_ITEM]: (node: StoryblokRichTextNode<string>, ctx) => {
     // Custom list item with enhanced styling
     const children = node.children || '';
     return ctx.render('li', {
       class: 'custom-list-item',
       'data-item': 'true'
     }, `<span class="bullet">→</span> ${children}`);
   },
},
}).render(doc);

Optimize images

To optimize images, use the optimizeImages property on the richTextResolver options. For a full list of available options, refer to the Image Service documentation.

import { richTextResolver } from "@storyblok/richtext";

const html = richTextResolver({
  optimizeImages: {
    class: "my-peformant-image",
    loading: "lazy",
    width: 800,
    height: 600,
    srcset: [400, 800, 1200, 1600],
    sizes: ["(max-width: 400px) 100vw", "50vw"],
    filters: {
      format: "webp",
      quality: 10,
      grayscale: true,
      blur: 10,
      brightness: 10,
    },
  },
}).render(doc);

Markdown to Storyblok rich text

Introduced in 3.6.0

The package now includes a powerful utility for converting Markdown content to Storyblok’s rich text format, which can be rendered with the existing richTextResolver.

Supported markdown elements:

• Text formatting: **bold**, *italic*, ~~strikethrough~~, `code`, [links](url)
• Headings: # H1 through ###### H6
• Lists: - unordered and 1. ordered lists with nesting
• Code blocks: ```fenced``` and indented blocks
• Blockquotes: > quoted text
• Images: ![alt](src "title")
• Links: [text](url) and [text](url "title")
• Tables: Standard markdown table syntax
• Horizontal rules: ---
• Line breaks: (two spaces) for hard breaks

import { markdownToStoryblokRichtext } from "@storyblok/richtext/markdown-parser";

const markdown = `
# Main Heading

This is a **bold** paragraph with *italic* text.

- List item 1
- List item 2

> This is a blockquote
`;

const richtextDoc = markdownToStoryblokRichtext(markdown);

// Convert to HTML using the existing richTextResolver
const html = richTextResolver().render(richtextDoc);
document.getElementById("content").innerHTML = html;

Similar to overwriting resolves via rich text options, you can customize how specific Markdown elements are converted by providing custom resolvers:

import { markdownToStoryblokRichtext, MarkdownTokenTypes } from "@storyblok/richtext/markdown-parser";

const markdown = "# Custom Heading\nThis is a paragraph with [a link](https://example.com).";

const richtextDoc = markdownToStoryblokRichtext(markdown, {
  resolvers: {
    // Custom link resolver
    [MarkdownTokenTypes.LINK]: (token, children) => {
      return {
        type: "link",
        attrs: {
          href: token.attrGet("href"),
          title: token.attrGet("title") || null,
          target: "_blank", // Always open in new tab
        },
        content: children,
      };
    },
  },
});

HTML to Storyblok rich text

Introduced in 3.7.0

The package includes a utility for converting HTML content to Storyblok’s rich text format, which can be rendered with the existing richTextResolver.

Supported HTML elements:

• Headlines: <h1-6>
• Paragraphs: <p>
• Lists: <ol>, <ul>, <li>
• Tables: <table>, <thead>, <tbody> , <tr>, <th>, <td>
• Blockquote: <blockquote>
• Code: <pre>, <code>
• Links: <a>
• Formatting: <strong>, <b>, <em>, <i>, <del>, <s>
• Images: <img>
• Misc: <span>, <hr>, <br>

import { htmlToStoryblokRichtext } from "@storyblok/richtext/html-parser";

const html = `
<h1>Main Heading</h1>

<p>This is a <strong>bold</strong> paragraph with <em>italic</em> text.</p>

<ul>
 <li>List item 1</li>
 <li>List item 2</li>
</ul>

<blockquote>
 <p>This is a blockquote</p>
</blockquote>
`;

const richtextDoc = htmlToStoryblokRichtext(html);

// Convert to HTML using the existing richTextResolver
const html = richTextResolver().render(richtextDoc);
document.getElementById("content").innerHTML = html;

Similar to overwriting resolves via richtext options, you can customize how specific HTML elements are converted by providing custom resolvers:

import { htmlToStoryblokRichtext, HTMLTags } from "@storyblok/richtext/html-parser";

const html = '<h1>Custom Heading\nThis is a paragraph with <a href="https://example.com">a link</a>.</h1>';

const richtextDoc = htmlToStoryblokRichtext(html, {
  resolvers: {
    // Custom link resolver
    [HTMLTags.A]: (node, content) => {
      return {
        type: "link",
        attrs: {
          href: node.attrs.href,
          title: node.attrs.title || null,
          target: "_blank", // Always open in new tab
        },
        content,
      };
    },
  },
});

Framework usage

The @storyblok/richtext package is framework-agnostic and can be used with any JavaScript-based frontend framework. Below are examples of how to use the package with different frameworks.

React

Note

For a better developer experience, use the corresponding APIs available in the framework SDK, such as the StoryblokRichText component in @storyblok/react. Learn more in the @storyblok/react reference.

import React from 'react';
import { richTextResolver } from '@storyblok/richtext';

const options: StoryblokRichTextOptions<ReactElement> = {
renderFn: React.createElement,
keyedResolvers: true,
};

function Example({ doc }) {
  const html = richTextResolver(options).render(doc);
  return <>{formattedHtml}</>;
}

Refer to playground/react in the @storyblok/richtext package repository for a complete example.

Vue

Note

For a better developer experience, use the corresponding APIs available in the framework SDK, such as the StoryblokRichText component in @storyblok/vue. Learn more in the @storyblok/vue reference.

<script setup>
  import type { VNode } from 'vue';
  import { createTextVNode, h } from 'vue';
  import { BlockTypes, richTextResolver, type StoryblokRichTextNode, type StoryblokRichTextOptions } from '@storyblok/richtext';

  const options: StoryblokRichTextOptions<VNode> = {
    renderFn: h,
    textFn: createTextVNode,
    keyedResolvers: true,
  };

  const root = () => richTextResolver<VNode>(options).render(doc);
</script>

<template>
  <root />
</template>

Refer to playground/vue in the @storyblok/richtext package repository for a complete example.

TypeScript Generics

Correct type support in a framework-agnostic way is ensured by using Typescript Generics, circumventing the need to import types and require framework packages as dependencies.

Vanilla: string

const options: StoryblokRichTextOptions<string> = {
resolvers: {
  [MarkTypes.LINK]: (node: Node<string>) => {
    return `<button href="${node.attrs?.href}" target="${node.attrs?.target}">${node.children}</button>`;
  },
},
};

const html = richTextResolver < string > options.render(doc);

React: React.ReactElement

const options: StoryblokRichTextOptions<React.ReactElement> = {
renderFn: React.createElement,
keyedResolvers: true,
};
const root = () => richTextResolver < React.ReactElement > options.render(doc);

Vue: VNode

const options: StoryblokRichTextOptions<VNode> = {
renderFn: h,
keyedResolvers: true,
};
const root = () => richTextResolver < VNode > options.render(doc);
