Implementing the Syncfusion Vue Rich Text Editor

The Syncfusion Vue Rich Text Editor (ejs-richtexteditor) is a single, unified editor component that supports two primary modes:

• HTML mode (default) — WYSIWYG editor that returns valid HTML markup
• Markdown mode — plain-text editing with Markdown syntax, rendered via a third-party library like marked

Both modes share the same Vue component and @syncfusion/ej2-vue-richtexteditor package. The editorMode prop and the injected service module (HtmlEditor vs MarkdownEditor) are what differentiate them.

When to Use This Skill

• User wants to add a rich text / WYSIWYG editor to a Vue app
• User wants a Markdown editor with preview support
• User needs to customize the toolbar (types, items, sticky, floating)
• User wants to insert images, audio, video, tables, or links
• User needs paste-from-Word cleanup, inline editing, or IFrame mode
• User wants to integrate AI Assistant, slash menu, emoji picker, or @mentions
• User needs form validation, read-only mode, or XHTML validation
• User needs to get/set editor value or work with events and selection API

Mode Selection Guide

Goal	Mode	Inject
WYSIWYG HTML output	editorMode="HTML" (default)	HtmlEditor
Markdown text with #, **bold** syntax	editorMode="Markdown"	MarkdownEditor
IFrame-isolated editing	HTML mode + IFrame config	HtmlEditor, HtmlEditor render mode
Live markdown preview split-pane	Markdown mode + marked library	MarkdownEditor

Quick Start

npm install @syncfusion/ej2-vue-richtexteditor

npm install @syncfusion/ej2-tailwind3-theme

HTML Editor (Composition API)

<template>
  <ejs-richtexteditor :value="value" :toolbarSettings="toolbarSettings" />
</template>

<script setup>
import { provide } from 'vue';
import {
  RichTextEditorComponent as EjsRichtexteditor,
  Toolbar, Link, Image, HtmlEditor, QuickToolbar
} from '@syncfusion/ej2-vue-richtexteditor';

const value = '<p>Start editing here...</p>';
const toolbarSettings = {
  items: ['Bold', 'Italic', 'Underline', '|', 'Formats', 'Alignments',
    'OrderedList', 'UnorderedList', '|', 'CreateLink', 'Image', '|', 'Undo', 'Redo']
};
provide('richtexteditor', [Toolbar, Link, Image, HtmlEditor, QuickToolbar]);
</script>

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

Markdown Editor (Composition API)

<template>
  <ejs-richtexteditor
    editorMode="Markdown"
    :value="value"
    :toolbarSettings="toolbarSettings"
  />
</template>

<script setup>
import { provide } from 'vue';
import {
  RichTextEditorComponent as EjsRichtexteditor,
  Toolbar, Link, Image, MarkdownEditor
} from '@syncfusion/ej2-vue-richtexteditor';

const value = '**Hello** from Markdown editor!';
const toolbarSettings = {
  items: ['Bold', 'Italic', 'StrikeThrough', '|',
    'Formats', 'OrderedList', 'UnorderedList', '|',
    'CreateLink', 'Image', '|', 'Undo', 'Redo']
};
provide('richtexteditor', [Toolbar, Link, Image, MarkdownEditor]);
</script>

Key Module Injection Reference

Feature	Module to Inject
HTML editing (default)	HtmlEditor
Markdown editing	MarkdownEditor
Toolbar	Toolbar
Hyperlinks	Link
Images	Image
Audio	Audio
Video	Video
Tables	Table
Quick toolbars	QuickToolbar
Paste cleanup	PasteCleanup
Slash menu	SlashMenu
AI Assistant	AIAssistantService
Character count	Count

Always inject modules in provide('richtexteditor', [...modules]).

Common Patterns

Controlled value with v-model

<ejs-richtexteditor v-model:value="content" />

Getting value programmatically

<ejs-richtexteditor ref="rteRef" />
<!-- In script: -->
const html = rteRef.value.ej2Instances.getHTML();
const text = rteRef.value.ej2Instances.getText();

Markdown editor + live HTML preview

Use editorMode="Markdown" with a change event handler that passes the content through marked.parse() into a preview <div>. See references/editor-modes.md for the full split-pane implementation.

Decide: HTML mode or Markdown mode?

• Need formatted output to store as HTML → use HTML mode
• Need lightweight text with syntax users can read/edit as plain text → use Markdown mode
• Need rich media (images, video, audio, tables with formatting) → use HTML mode
• Need developer-friendly source that renders in GitHub/Notion → use Markdown mode
