mdx-editor/editor

A rich text editor React component for markdown

Summary

MDXEditor is an open-source React component that provides a WYSIWYG-style editing experience for markdown, similar to Google Docs or Notion. It is written in TypeScript, distributed as an npm package (@mdxeditor/editor), and is built on the Lexical editor framework (per the repository topics). The project is released under the MIT license.

What it is useful for

The component is useful when engineers need to embed rich markdown authoring directly into a web app rather than relying on a plain text area. According to the README, it supports core markdown syntax plus extensions including tables, images, and code blocks, and it also allows users to edit JSX components, either through a built-in JSX editor or a custom one supplied by the integrator.

Typical use cases include:

• Adding a Notion-like document editor to a React product or internal tool.
• Letting users author MDX (markdown + JSX) without manually writing angle-bracket syntax.
• Building content pipelines where the resulting string is markdown, but the input experience is visual.
• Projects that want a typed component (TypeScript) and the option to plug in custom JSX editing behavior.

The README does not document specific performance characteristics or claim compatibility with any particular framework beyond React, so those details are not covered here.

How engineers can use it

The README provides a minimal starting example:

import {MDXEditor, headingsPlugin} from '@mdxeditor/editor';
import '@mdxeditor/editor/style.css';

export default function App() {
  return <MDXEditor markdown={'# Hello World'} plugins={[headingsPlugin()]} />;
}

From this, the integration pattern is:

1. Install the @mdxeditor/editor npm package.
2. Import the MDXEditor component along with any plugins you need (for example headingsPlugin).
3. Import the bundled stylesheet (@mdxeditor/editor/style.css) so the editor renders correctly.
4. Render <MDXEditor markdown={...} plugins={[...]} /> inside a React app, passing the initial markdown as a string and an array of plugins.

The README points engineers to the official documentation site (https://mdxeditor.dev/editor/docs/getting-started) for full setup, plugin configuration, and theming. Bug reports go to the GitHub issues page, and general questions can be raised in the GitHub Discussions section. For commercial integration support, the README lists a direct email contact.
