GrapesJS MJML

Requires GrapesJS v0.15.9 or higher

This plugin enables the usage of MJML components inside the GrapesJS environment. MJML components are rendered in real-time using the official v4 compiler (+ some mocks to make it run in the browser), therefore the result is, almost, the same as using the MJML Live Editor.

Demo

Supported MJML components: mj-mjml mj-head mj-body mj-wrapper mj-group mj-section mj-column mj-text mj-image mj-button mj-social mj-social-element mj-divider mj-spacer mj-style mj-font mj-hero mj-navbar mj-navbar-link mj-raw

Usage

<link href="path/to/grapes.min.css" rel="stylesheet"/>
<script src="path/to/grapes.min.js"></script>
<script src="path/to/grapesjs-mjml.min.js"></script>

<div id="gjs">
  <mjml>
    <mj-body>
      <!-- Your MJML body here -->
      <mj-section>
        <mj-column>
          <mj-text>My Company</mj-text>
        </mj-column>
      </mj-section>
    </mj-body>
  </mjml>
</div>

<script type="text/javascript">
  const editor = grapesjs.init({
      fromElement: true,
      container: '#gjs',
      plugins: ['grapesjs-mjml'],
      pluginsOpts: {
        'grapesjs-mjml': {/* ...options */}
      }
  });
</script>

Or using ESM imports:

import 'grapesjs/dist/css/grapes.min.css'
import grapesJS from 'grapesjs'
import grapesJSMJML from 'grapesjs-mjml'

grapesJS.init({
   fromElement: true,
   container: '#gjs',
   plugins: [grapesJSMJML],
   pluginsOpts: {
      [grapesJSMJML]: {/* ...options */}
   },
});

i18n usage:

import 'grapesjs/dist/css/grapes.min.css'
import grapesJS from 'grapesjs'
import nl from 'grapesjs/locale/nl'
import grapesJSMJML from 'grapesjs-mjml'
import mjmlNL from 'grapesjs-mjml/locale/nl'

grapesJS.init({
   fromElement: true,
   container: '#gjs',
   i18n: {
      // locale: 'en', // default locale
      // detectLocale: true, // by default, the editor will detect the language
      // localeFallback: 'en', // default fallback
      messages: { nl: nl },
   },
   plugins: [grapesJSMJML],
   pluginsOpts: {
      [grapesJSMJML]: {
        // Optional options
        i18n: { nl: mjmlNL }
      }
   },
});

fonts usage:

import 'grapesjs/dist/css/grapes.min.css'
import grapesJS from 'grapesjs'
import grapesJSMJML from 'grapesjs-mjml'

const editor = grapesJS.init({
   fromElement: true,
   container: '#gjs',
   plugins: [grapesJSMJML],
   pluginsOpts: {
      [grapesJSMJML]: {
        // The font imports are included on HTML <head/> when fonts are used on the template
        fonts: {
          Montserrat: 'https://fonts.googleapis.com/css?family=Montserrat',
          'Open Sans': 'https://fonts.googleapis.com/css?family=Open+Sans'
        }
      }
   },
});

// add custom fonts options on editor's font list
editor.on('load', () => {
  const styleManager = editor.StyleManager;
  const fontProperty = styleManager.getProperty('typography', 'font-family');

  const list = [];
  // empty list
  fontProperty.set('list', list);

  // custom list
  list.push(fontProperty.addOption({value: 'Montserrat, sans-serif', name: 'Montserrat'}));
  list.push(fontProperty.addOption({value: 'Open Sans, sans-serif', name: 'Open Sans'}));
  fontProperty.set('list', list);

  styleManager.render();
});
