Here, we have a new rich text editor called Editable, which does not use the native editable property contenteditable, but instead uses a custom renderer. This approach allows us to better control the behavior of the editor.


A rich text editor that supports collaborative editing, you can freely use React, Vue and other front-end common libraries to extend and define plugins.

Getting Started


The editor consists of the engine, toolbar, and plugins. The engine provides us with the core editing capability.

Use npm or yarn to install the engine package.

$ npm install @aomao/engine
# or
$ yarn add @aomao/engine


We'll start by outputting a "Hello world!" message as usual.

import React, { useEffect, useRef, useState } from 'react';
import Engine, { EngineInterface } from '@aomao/engine';

const EngineDemo = () => {
	//Editor container
	const ref = useRef<HTMLDivElement | null>(null);
	//Engine instance
	const [engine, setEngine] = useState<EngineInterface>();
	//Editor content
	const [content, setContent] = useState<string>('<p>Hello world!</p>');

	useEffect(() => {
		if (!ref.current) return;
		//Instantiate the engine
		const engine = new Engine(ref.current);
		//Set the editor value
		//Listen to the editor value change event
		engine.on('change', () => {
			const value = engine.getValue();
		//Set the engine instance
	}, []);

	return <div ref={ref} />;
export default EngineDemo;


Import the @aomao/plugin-bold bold plugin.

import Bold from '@aomao/plugin-bold';

Add the Bold plugin to the engine.

//Instantiate the engine
const engine = new Engine(ref.current, {
	plugins: [Bold],


A card is a separately defined area in the editor, with its UI and logic for rendering custom content inside the card using React, Vue, or other front-end libraries before being mounted onto the editor.

Introduce @aomao/plugin-codeblock, a code block plugin with a language drop-down that is rendered using React, which distinguishes it from Vue3 using @aomao/plugin-codeblock-vue.

import CodeBlock, { CodeBlockComponent } from '@aomao/plugin-codeblock';

Add the CodeBlock plugin and the CodeBlockComponent card component to the engine.

//Instantiate the engine
const engine = new Engine(ref.current, {
	plugins: [CodeBlock],
	cards: [CodeBlockComponent],

The CodeBlock plugin supports markdown by default. You can trigger it by typing the code block syntax at the beginning of a line in the editor, followed by a space and the language name, such as ```javascript.

Node Constraints

To manage nodes more conveniently and reduce complexity, the editor abstracts node properties and functionality and defines four types of nodes: mark, inline, block, and card. They are composed of different attributes, styles, or HTML structures, and are uniformly constrained using a schema.

A simple schema looks like this:

  name:'p', // node name
  type:'block' // node type

In addition, properties, styles, etc. can also be described, for example:

  name:'span', // node name
  type:'mark', // node type
  attributes: {
    // The node has a style attribute
    style: {
      // Must contain a color style
      color: {
        required: true, // must contain
        value:'@color' // The value is a color value that conforms to the css specification. @color is the color validation defined in the editor. Here, methods and regular expressions can also be used to determine whether the required rules are met
    // Optional include a test attribute, its value can be arbitrary, but it is not required

The following types of nodes conform to the above rules:

<span style="color:#fff"></span>
<span style="color:#fff" test="test123" test1="test1"></span>
<span style="color:#fff;background-color:#000;"></span>
<span style="color:#fff;background-color:#000;" test="test123"></span>

But except that color and test have been defined in schema, other attributes (background-color, test1) will be filtered out by the editor during processing.

The nodes in the editable area have four types of combined nodes of mark, inline, block, and cardthrough theschemarule. They are composed of different attributes, styles orhtml` structures. Certain constraints are imposed on nesting.


Import the @aomao/toolbar toolbar. Due to the complex interaction, the toolbar is basically rendered using React + Antd UI components, while Vue3 uses @aomao/toolbar-vue

Except for UI interaction, most of the work of the toolbar is just to call the engine to execute the corresponding plugin commands after different button events are triggered. In the case of complicated requirements or the need to re-customize the UI, it is easier to modify after the fork.

import Toolbar, { ToolbarPlugin, ToolbarComponent } from '@aomao/toolbar';

Add the ToolbarPlugin plugin and ToolbarComponent card component to the engine, which allows us to use the shortcut key / in the editor to wake up the card toolbar

//Instantiate the engine
const engine = new Engine(ref.current, {
	plugins: [ToolbarPlugin],
	cards: [ToolbarComponent],

Rendering toolbar, the toolbar has been configured with all plugins, here we only need to pass in the plugin name

return (
        engine && (

For more complex toolbar configuration, please check the document

Collaborative Editing

This open-source library listens to changes in the HTML structure of the editing area (contenteditable root node), uses MutationObserver to reverse-engineer the data structure, and connects and interacts with Yjs through WebSocket to achieve multi-user collaborative editing.

Interactive mode

Each editor, as a client, communicates and interacts with the server through the WebSocket function in the @aomao/plugin-yjs-websocket plugin.

  • @aomao/yjs implements the conversion of editor and Yjs data
  • @aomao/plugin-yjs-websocket provides the WebSocket client function of the editor and Yjs
  • @aomao/plugin-yjs-websocket/server provides the WebSocket server of Yjs, written in Node.js, and supports data storage using MongoDB and LevelDB.

Project icon




Before using this open-source library, you need to install dependencies in the project root directory.

yarn install

leran bootstrap

After installing the dependencies, you only need to execute the following command in the root directory to start the project:

yarn start

The development directory structure of this open-source library is as follows:

  • packages contains the engine and toolbar-related code
  • plugins contains all plugins
  • api provides API access required by some plugins, and uses as the default API service
  • yjs-server contains collaborative server code, which can be started by yarn dev.
