Bundling an npm version of TinyMCE with ES6 and Rollup.js

The following procedure will assist with bundling an npm version of TinyMCE with Rollup.js using ES6+ syntax. The procedure assumes the user has experience with Rollup.js and ES6+ syntax. The following steps provide a working example for bundling a basic TinyMCE configuration with Rollup.js, and provides links to reference pages at the end of the procedure for bundling additional customizations with the editor.

If TinyMCE will be used with a JavaScript framework (such as React.js, Angular, or Vue.js) the bundle will also require the relevant framework integration package (where available). For a list of supported framework integrations, see: Installing TinyMCE.

Requirements

This guide requires the following:

  • Node.js and npm

  • Basic knowledge of how to use Rollup.js

  • (Optional: For premium features) The latest premium .zip bundle of TinyMCE for including premium plugins

Procedure

  1. Add tinymce and the following development dependencies to the project.

  2. Create a new source file for importing the required components from TinyMCE and configuring the editor.

    The following components are required to bundle TinyMCE:

    • The tinymce global

    • The silver theme

    • The dom model

    • The default icon pack. This is always required and provides the base set of icons for all TinyMCE functionality. The default icons can be extended or overridden using additional icon packs.

    • A skin for styling the user interface, including toolbars and menus. This can be a community, premium or custom skin.

    • A content skin for styling UI features within the content such as table and image resizing. This can be a community, premium or custom skin.

    The global must be first, the rest can be in any order.

    Additional components that are optional but recommended:

    • Content CSS for styling editor content. There are community and premium style skins available, or use custom content CSS.

    • Plugins to be used with the editor.

    • A custom or premium icon pack to extend or override the default icons for toolbar buttons, including contextual toolbars. This can be a premium or custom icon pack.

    Example src/editor.js

    /* Import TinyMCE */
import tinymce from 'tinymce';

/* Default icons are required. After that, import custom icons if applicable */
import 'tinymce/icons/default';

/* Required TinyMCE components */
import 'tinymce/themes/silver';
import 'tinymce/models/dom';

/* Import a skin (can be a custom skin instead of the default) */
import 'tinymce/skins/ui/oxide/skin.css';

/* Import plugins */
import 'tinymce/plugins/advlist';
import 'tinymce/plugins/code';
import 'tinymce/plugins/emoticons';
import 'tinymce/plugins/emoticons/js/emojis';
import 'tinymce/plugins/link';
import 'tinymce/plugins/lists';
import 'tinymce/plugins/table';

/* Import premium plugins by replacing <plugincode> */
/* NOTE: Download separately and add these to /src/plugins */
/* import './plugins/<plugincode>'; */

/* content UI CSS is required */
import contentUiSkinCss from 'tinymce/skins/ui/oxide/content.css';

/* The default content CSS can be changed or replaced with appropriate CSS for the editor content. */
import contentCss from 'tinymce/skins/content/default/content.css';

/* Initialize TinyMCE */
export function render () {
  tinymce.init({
    selector: 'textarea#editor',
    plugins: 'advlist code emoticons link lists table',
    toolbar: 'bold italic | bullist numlist | link emoticons',
    skin: false,
    content_css: false,
    content_style: contentUiSkinCss.toString() + '\n' + contentCss.toString(),
  });
};

  3. Update the project Rollup.js configuration to load the TinyMCE CSS.

    Example rollup.config.js

    import postcss from 'rollup-plugin-postcss';
import commonjs from '@rollup/plugin-commonjs';
import { nodeResolve } from '@rollup/plugin-node-resolve';

export default {
  input: 'src/index.js',
  plugins: [
    nodeResolve(),
    commonjs(),
    postcss({
      include: "**/skin.css",
      inject: false,
      extract: true
    }),
    postcss({
      include: "**/content.css",
      inject: false,
      extract: false
    })
  ],
  output: {
    file: 'dist/main.bundle.js',
    format: 'umd'
  }
};

  4. Add the TinyMCE assets and configuration into the project and provide a target element to initialize the editor.

    Example src/index.js

    import * as editor from './editor';

const editorArea = () => {
  const element = document.createElement('textarea');
  element.id = 'editor';
  return element
};

const parent = document.createElement('p');
parent.appendChild(editorArea());
document.body.appendChild(parent);

editor.render();

    Example demo.html

    <!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>TinyMCE Rollup Demo</title>
    <link rel="stylesheet" href="main.bundle.css">
  </head>
  <body>
    <h1>TinyMCE Rollup Demo</h1>
    <script src="main.bundle.js"></script>
  </body>
</html>

  5. Run Rollup.js to test the bundle, such as:

    rollup --config

    If Rollup.js runs successfully, check that the editor loads in the application. If Rollup.js fails, review any errors and review the configuration changes in this procedure; you may need to adjust for conflicts or other issues when bundling TinyMCE into an existing project.
