JavaScript Block Editor Component

Using this package with an AI coding agent

Before generating Syncfusion code, ask your AI coding agent to run the Syncfusion setup using the following prompt:

Set up this project for Syncfusion before generating code. Fetch
and follow the official instructions at https://ai.syncfusion.com,
then report the detected platform, installed skill pack, MCP
status, and any required licensing action.

The setup detects your project’s platform and loads the appropriate Syncfusion skill pack. No Syncfusion account or MCP key is required to install or read Syncfusion agent skills.

Platform reference: https://ai.syncfusion.com/javascript/llms.txt

JavaScript Block Editor Control

️ Quick Start

This guide uses Vite as the bundler and development environment for the JavaScript Block Editor. Install Node.js 24.13.0 or higher before proceeding. For detailed information about Vite's capabilities and configuration options, refer to the Vite documentation.

Create a TypeScript application

To set up a TypeScript application, run the following command.

npm create vite@latest my-app -- --template vanilla-ts

This command will prompt you to install the required packages and start the application. As Syncfusion packages are not installed yet, select the No option.

Then, navigate to the project directory and install the dependencies:

cd my-app
npm install
Install the Block Editor package
npm install @syncfusion/ej2-blockeditor
Add the CSS reference

Install the Syncfusion Tailwind 3 theme package:

npm install @syncfusion/ej2-tailwind3-theme --save

Then add the following CSS reference to the src/style.css file:

@import "../node_modules/@syncfusion/ej2-tailwind3-theme/styles/blockeditor/index.css";
Add the Block Editor component to your application

In the index.html file, add a target element:

<!DOCTYPE html>
<html>
  <body>
    <!-- Your Block Editor container -->
    <div id="blockEditor"></div>
    <script type="module" src="/src/main.ts"></script>
  </body>
</html>

In the src/main.ts file, import the Block Editor component as shown below:

import { BlockEditor } from '@syncfusion/ej2-blockeditor';
import './style.css';

const editor = new BlockEditor({
  height: '500px'
});
editor.appendTo('#blockEditor');
Run the application
npm run dev

Now, open your project in a browser, and the Block Editor will be displayed!
