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 (using default mjml-browser parser): 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

npm i grapesjs-mjml

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 }
      }
   },
});

Using Independent mjml-browser Build

In case, you have your own version of MJML with custom or extended components, it is possible to override default mjml parser with custom one and create custom grapesJS components.

For further info how to create MJML Component, you can visit components folder or you can go to docs.

import 'grapesjs/dist/css/grapes.min.css'
import grapesJS from 'grapesjs'
import grapesJSMJML from 'grapesjs-mjml'
import customMjmlParser from 'custom-mjml-parser';

import customImage from 'custom/components/path'

grapesJS.init({
   fromElement: true,
   container: '#gjs',
   plugins: [grapesJSMJML],
   pluginsOpts: {
      [grapesJSMJML]: {
        mjmlParser: customMjmlParser,
        customComponents: [
          customImage,
        ]
      }
   },
});
