Shopify Rich Text Renderer

This package converts the rich text schema returned by Shopify's Storefront API to an HTML string. In particular, this package is useful when dealing with the rich text field type for MetaObjects and Metafields when using the Storefront API.

Usage

• Install yarn add @thebeyondgroup/shopify-rich-text-renderer
• Then import the convertSchemaToHtml() function

import { convertSchemaToHtml } from '@thebeyondgroup/shopify-rich-text-renderer'

/*  this is an example of the rich text Shopify returns
const richTextResponse = {\"type\":\"root\",\"children: [{\"type\":\"heading\"
\"level\":1,\"children\":[{\"type\":\"text\",\"value\":\
"Test Heading\"}]},{\"listType\":\"ordered\",\"type\":\"list\",
\"children\":[{\"type\":\"list-item\",\"children\":..." */

convertSchemaToHtml(richTextResponse)

<!-- Output: -->
<h1>Test Heading</h1>
<ol>
  ...
</ol>
...

To get scoped HTML pass either true or the name of a class(es) to use in your scoped css selectors in the scoped property of the options parameter (options.scoped). This allows for the rich text HTML to be easily styled. Note: You can also pass a scoped class name or true(to use default scoped class) instead of the options object, i.e. convertSchemaToHtml(richTextResponse, 'rich-text-wrap').

// scoped html
convertSchemaToHtml(richTextResponse, { scoped: true })

<!-- Output: -->
<div class="rte">
  <h1>Test Heading</h1>
  <ol>
    ...
  </ol>
  ...
</div>

You can also pass in a custom class name to be used as the scoped class instead of the default rte.

//scoped w/ custom class name
convertSchemaToHtml(richTextResponse, { scoped: 'rich-text-wrap' })

<!-- Output: -->
<div class="rich-text-wrap">
  <h1>Test Heading</h1>
  <ol>
    ...
  </ol>
  ...
</div>

If you want to be more specific or are using something like Tailwind CSS you can pass a string of classes to be used with specific HTML elements to the classes property of the options parameter (options.classes). This makes it easy to write your own wrapper class to apply a default classlist to various elements. There is also an option to convert new line character's to <br/> ( You can create new lines using shift + space in Shopify's rich text editor).

const options = {
  scoped: false,
  newLineToBreak: true, // convert new line character to <br/>
  classes: {
    p: 'mt-3 text-lg', // paragraph classes
    h1: 'mb-4 text-2xl md:text-4xl', // heading1 classes
    h2: 'mb-4 text-xl md:text-3xl', // heading2 classes
    h3: 'mb-3 text-lg md:text-2xl', // heading3 classes
    h4: 'mb-3 text-base md:text-lg', // heading4 classes
    h5: 'mb-2.5 text-sm md:text-base', // heading5 classes
    h6: 'mb-2 text-xs md:text-sm', // heading6 classes
    ol: 'my-3 ml-3 flex flex-col gap-y-2', // order list classes
    ul: 'my-3 ml-3 flex flex-col gap-y-2', // unordered list classes
    li: 'text-sm md:text-base', // list item classes
    a: 'underline text-blue-500 hover:text-blue-700', // anchor/link classes
    strong: 'font-medium', // bold/strong classes
    em: 'font-italic', // italic/em classes
  },
}

// Applying classes directly to elements
convertSchemaToHtml(richTextResponse, options)

<!-- Output: -->
<h1 class="mb-4 text-2xl md:text-4xl">Groceries</h1>
<p class="mt-3 text-lg">
  Here is my shopping list for various fruit to buy at
  <a href="https://grocerystore.com" class="underline text-blue-500 hover:text-blue-700"> The Grocery Store </a>
</p>
<ol class="my-3 ml-3 flex flex-col gap-y-2">
  <li class="text-sm md:text-base">apples</li>
  <li class="text-sm md:text-base">oranges</li>
  <li class="text-sm md:text-base">bananas</li>
</ol>
...

React/Hydrogen example:

export default RenderedHTML(){
 const richTextResponse  = await getRichTextFromShopify()
  return (
   <>
    <div
        className="html"
        dangerouslySetInnerHTML={{
          __html: convertSchemaToHtml(richTextResponse),
          }}
         />
      <div>
   </>
 )
}
