Syncfusion React Rich Text Editor

Syncfusion React Rich Text Editor

A WYSIWYG (What You See Is What You Get) editor for creating and formatting rich content as HTML or Markdown. Supports toolbars, media insertion, AI assistance, smart editing features, form validation, and deep customization.

When to Use This Skill

• Setting up a rich text / WYSIWYG editor in a React app
• Configuring toolbar items, types, or positions
• Switching between HTML and Markdown editor modes
• Inserting images, video, audio, or files
• Working with smart editing features: emoji, slash menu, mentions, mail merge
• Integrating AI assistant into the editor
• Handling editor value: get, set, two-way binding, auto-save, import/export
• Applying paste cleanup, form validation, or read-only mode
• Customizing styles, accessibility, or keyboard shortcuts

Quick Start

npm install @syncfusion/ej2-react-richtexteditor

npm install @syncfusion/ej2-tailwind3-theme

src/App.css - add CSS imports

@import '../node_modules/@syncfusion/ej2-tailwind3-theme/styles/rich-text-editor/index.css';

import './App.css';import {  HtmlEditor, Image, Inject, Link,  QuickToolbar, RichTextEditorComponent, Toolbar} from '@syncfusion/ej2-react-richtexteditor';
function App() {  return (    <RichTextEditorComponent height={450}>      <Inject services={[Toolbar, Image, Link, HtmlEditor, QuickToolbar]} />    </RichTextEditorComponent>  );}export default App;

Module Injection Reference

Inject only the modules your app needs — this keeps the bundle lean.

Common Patterns

Read value on change

import { ChangeEventArgs } from '@syncfusion/ej2-react-richtexteditor';
function App() {  const onChange = (args: ChangeEventArgs) => {    console.log(args.value); // HTML string  };  return (    <RichTextEditorComponent change={onChange}>      <Inject services={[Toolbar, HtmlEditor]} />    </RichTextEditorComponent>  );}

Controlled value with React state

const [content, setContent] = useState('<p>Hello</p>');<RichTextEditorComponent value={content} change={(e) => setContent(e.value)}>  <Inject services={[Toolbar, HtmlEditor]} /></RichTextEditorComponent>

Markdown mode

import { MarkdownEditor } from '@syncfusion/ej2-react-richtexteditor';<RichTextEditorComponent editorMode="Markdown">  <Inject services={[Toolbar, MarkdownEditor]} /></RichTextEditorComponent>
