Display WYSIWYG content (legacy)

WYSIWYG stands for What You See Is What You Get. It means that your back office users write their content without needing any HTML or React knowledge. This is the case in most CMS tools nowadays. The output though is usually HTML which does not necessarly match the React components you've built in your Front-Commerce application.

This is why we've built a theme/modules/Wysiwyg component in Front-Commerce. By default it takes a content property which contains the HTML that needs to be parsed, and transforms it in React components.

The <Wysiwyg /> component

The <Wysiwyg /> component applies two types of transformations to your HTML :

• shortcodes
• transforms

Shortcodes

Shortcodes are custom strings that can be parsed and transformed to HTML strings.

In Magento, they look like {% raw %}{{gallery id="123" size="medium"}}{% endraw %}. In Wordpress they are like [gallery id="123" size="medium"]. But ultimately, they can be whatever string you want. The goal is to match a given regex, and transform it to some HTML string.

For instance, for Magento, we parse {% raw %}{{media}}{% endraw %} shortcodes and replace them with <img> tags. It looks like this:

{
  // regex to identify the shortcode within your HTML code
  regex: /\{\{media url="(.*?)"\}\}/gi,
  // How to replace the given shortcode
  replacement: (match, url) => `/media/${url}`
}

See EnhanceWysiwyg's reference for more details.

Transforms

Transforms are functions that take an HTML node and transform it in a React Element.

For instance, we want to make sure that it transforms <a> tags to Link elements to preserve React's navigation. For instance, <a href="/about-us">About us</a> will be transformed to <Link to="/about-us">About us</Link>. It looks like this:

export default (node, convertNodeToElement) => {
  if (node.name === "a") {
    const target = node.attribs && node.attribs.href;
    const isExternal = !target || /^(https?:)?\/\//.test(target);

    if (!isExternal) {
      return (
        <Link to={target} external={isExternal}>
          {node.children.map(convertNodeToElement)}
        </Link>
      );
    }
  }
};

Platform specific Wysiwyg components

Magento: theme/modules/Wysiwyg/MagentoWysiwyg

Shortcodes

Supported shortcodes:

• {% raw %}{{media url="*"}}{% endraw %}
• {% raw %}{{store url="*"}}{% endraw %}
• {% raw %}{{widget type="*" attribute="value"}}{% endraw %}

Any other shortcode will be removed from your final content.

Transforms

• <a> tags are transformed to the theme/components/atoms/Typography/Link component when the href attribute does not contain a domain.
• <widget> tags are transformed theme/modules/Wysiwyg/MagentoWysiwyg/Widget components. However, you shouldn't write a <widget> tag manually. It is in fact coming from the {% raw %}{{widget}}{% endraw %} shortcode.

Add a custom Magento Widget

Custom widgets will be automatically parsed. However, you will still need to map the widget's type to custom React Components. If you don't, they will be ignored.

To do so, please override theme/modules/Wysiwyg/MagentoWysiwyg/Widget.js in your own theme.

mkdir -p src/web/theme/modules/Wysiwyg/MagentoWysiwyg/
cp node_modules/front-commerce/src/web/theme/modules/Wysiwyg/MagentoWysiwyg/Widget.js \
  src/web/theme/modules/Wysiwyg/MagentoWysiwyg/Widget.js

Now, within your newly created Widget.js file, you will be able to add your own behavior. For instance, if you've created a widget in Magento with the type acme/product-preview, you will need to update the Widget.js file likewise:

+import React from "react";
import PropTypes from "prop-types";
+//import your matching React Component
+import ProductPreview from "theme/modules/ProductPreview";

const Widget = ({ type, attributes }) => {
+  // And match the type with your component
+  if (type === "acme/product-preview") {
+    return <ProductPreview sku={attributes.sku} />
+  }
+
  return null;
};

Widget.propTypes = {
  type: PropTypes.string.isRequired,
  attributes: PropTypes.object.isRequired
};

export default Widget;
