So how to use CodeX Editor


CodeX Editor is a Block-Styled editor. Blocks is a structural units, of which the Entry is composed. For example, Paragraph, Heading, Image, Video, List are Blocks. Each Block is represented by a Plugin. We have many ready-to-use Plugins and the simple API for creation new ones.

So how to use the Editor after Installation.

  • Create new Blocks by Enter or with the Plus Button
  • Press TAB or click on the Plus Button to view the Toolbox
  • Press TAB again to leaf Toolbox and select a Block you need. Then press Enter.

  • Select text fragment and apply a style or insert a link from the Inline Toolbar

  • Use «three-dots» button on the right to open Block Settings. From here, you can move and delete a Block or apply Tool's settings, if it provided. For example, set a Heading level or List style.


We really appreciate shortcuts. So there are few presets.

Action Shortcut Restrictions
TAB Show/leaf a Toolbox. On empty block
SHIFT+TAB Leaf back a Toolbox. While Toolbox is opened
ENTER Create a Block While Toolbox is opened and some Tool is selected
CMD+B Bold style On selection
CMD+I Italic style On selection
CMD+K Insert a link On selection

Also we support shortcuts on the all type of Tools. Specify a shortcut with the Tools configuration. For example:

var editor = CodexEditor({
  tools: {
    header: {
      class: Header,
      shortcut: 'CMD+SHIFT+H'
    list: {
      class: List,
      shortcut: 'CMD+SHIFT+L'

Installation Guide

There are few steps to run CodeX Editor on your site.

  1. Load Editor's core
  2. Load Tools
  3. Initialize Editor's instance

Load Editor's core

Firstly you need to get CodeX Editor itself. It is a minified script with minimal available

Choose the most usable method of getting Editor for you.

  • Node package
  • Source from CDN
  • Local file from project


Install the package via NPM or Yarn

npm i codex.editor --save-dev

Include module at your application

const CodexEditor = require('codex.editor');

Use from CDN

You can load specific version of package from jsDelivr CDN.

Then require this script.

<script src="..."></script>

Save sources to project

Copy codex-editor.js file to your project and load it.

<script src="codex-editor.js"></script>

Load Tools

Each Block at the CodeX Editor represented by Tools. There are simple external scripts with own logic. Probably you want to use several Block Tools that should be connected.

For example check out our Header Tool that represents heading blocks.

You can install Header Tool by the same way as the Editor (Node.js, CDN, local file).

Check CodeX Editor's community to see more ready-to-use Tools.

Example: use Header from CDN

<script src=""></script>

Create Editor instance

Create an instance of CodeX Editor and pass Configuration Object with holderId and tools list.

<div id="codex-editor"></div>

You can create a simple Editor with only default Paragraph Tool by passing a string with element's Id (wrapper for Editor) as a configuration param. Or use the default codex-editor id for wrapper.

var editor = new CodexEditor(); /** Zero-configuration */

// equals

var editor = new CodexEditor('codex-editor');

Or pass a whole settings object.

var editor = new CodexEditor({
     * Create a holder for the Editor and pass its ID
    holderId : 'codex-editor',

     * Available Tools list.
     * Pass Tool's class or Settings object for each Tool you want to use
    tools: {
        header: {
          class: Header,
          inlineToolbar : true
        // ...

     * Previously saved data that should be rendered
    data: {}

Saving Data

Call and handle returned Promise with saved data.
  .then((savedData) => {
