Storyblok Rich Text Renderer for React

Renders Storyblok rich text content to React elements.

Motivation

Storyblok provides a renderer for its rich text field type via their storyblok-js-client package. This renderer outputs HTML markup, which can be used in React via the dangerouslySetInnerHTML property:

import StoryblokClient from 'storyblok-js-client';

const Storyblok = new StoryblokClient({ accessToken: 'YOUR_TOKEN' });

function RichText({ document }) {
    const html = Storyblok.richTextResolver.render(document);
    return <div dangerouslySetInnerHTML={{ __html: html }} />;
}

Apart from being a bit awkward (dangerouslySetInnerHTML is, as the name implies, dangerous), this is problematic because it is not possible to map rich text elements to React components, e.g.:

1. Embedded Storyblok components
2. Links that you might want to pass through your app's router

Instead of HTML markup, storyblok-rich-text-react-renderer outputs React elements, and provides options to map any Stoyblok rich text element to custom React components.

Installation

npm install storyblok-rich-text-react-renderer

Usage

import { render } from 'storyblok-rich-text-react-renderer';

function RichText({ document }) {
    // document is the rich text object you receive from Storyblok,
    // in the form { type: "doc", content: [ ... ] }
    return <div>{render(document)}</div>;
}

Advanced usage

To map rich text elements to custom React components, resolvers can be passed via the optional second argument of the render function:

render(document, {
    markResolvers: { ... }, // inline elements
    nodeResolvers: { ... }, // block elements
    blokResolvers: { ... } // embedded components
});

Mark resolvers

Mark resolvers are used to map inline elements.

Use the nodeResolvers option to add mark resolvers.

Supported element types and their resolver function signatures are:

• MARK_BOLD - (children) => { ... }
• MARK_ITALIC - (children) => { ... }
• MARK_STRIKE - (children) => { ... }
• MARK_UNDERLINE - (children) => { ... }
• MARK_CODE - (children, { class }) => { ... }
• MARK_LINK - (children, { href, target, linktype }) => { ... }

Example: Map bold elements to <strong>

import { render, MARK_BOLD } from 'storyblok-rich-text-react-renderer';

render(document, {
    markResolvers: {
        [MARK_BOLD]: (children) => <strong>{children}</strong>
    }
});

Example: Map link elements to Next.js' <Link> component

import Link from 'next/link';
import { render, MARK_LINK } from 'storyblok-rich-text-react-renderer';

render(document, {
    markResolvers: {
        [MARK_LINK]: (children, props) => {
            const { href, target, linktype } = props;
            if (linktype === 'email') {
                // Email links: add `mailto:` scheme and map to <a>
                return <a href={`mailto:${href}`}>{children}</a>;
            }
            if (href.match(/^(https?:)?\/\//)) {
                // External links: map to <a>
                return <a href={href} target={target}>{children}</a>;
            }
            // Internal links: map to <Link>
            return <Link href={href}><a>{children}</a></Link>;
        }
    }
});

Node resolvers

Node resolvers are used to map block elements.

Use the nodeResolvers option to add node resolvers.

Supported element types and their resolver function signatures are:

• NODE_HEADING - (children, { level }) => { ... }
• NODE_CODEBLOCK - (children, { class }) => { ... }
• NODE_IMAGE - (children, { src, alt, title }) => { ... }
• NODE_PARAGRAPH - (children) => { ... }
• NODE_QUOTE - (children) => { ... }
• NODE_OL - (children) => { ... }
• NODE_UL - (children) => { ... }
• NODE_LI - (children) => { ... }
• NODE_HR - () => { ... }
• NODE_BR - () => { ... }

Example: Map image elements to custom React components

import MyImage from 'components/MyImage';
import { render, NODE_IMAGE } from 'storyblok-rich-text-react-renderer';

render(document, {
    nodeResolvers: {
        [NODE_IMAGE]: (children, props) => <MyImage {...props} />
    }
});

Blok resolvers

Blok resolvers are used to map embedded Storyblok components.

Use the blokResolvers option to add blok resolvers. Keys are the component's ("technical") name. The function signature is always (props) => { ... }, where props is an object that contains all the component's fields, as well as its _uid and _editable values.

Example: Map blok elements to custom React components

import MyComponent from 'components/MyComponent';
import { render } from 'storyblok-rich-text-react-renderer';

render(document, {
    blokResolvers: {
        ['my_component']: (props) => <MyComponent {...props} />
    }
});
