React Markdown Editor

A Markdown Editor for React.js, built with CodeMirror.

This is a work in progress. Format application and removal is not very robust, some formats are missing.

Live Demo

To build the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.


The easiest way to use codemirror is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).

You can also use the standalone build by including dist/codemirror.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install codemirror --save


var React = require('react'),
	Editor = require('react-md-editor');

var App = React.createClass({
	getInitialState: function() {
		return {
			code: "# Markdown"
	updateCode: function(newCode) {
			code: newCode
	render: function() {
		return <Editor value={this.state.code} onChange={this.updateCode} />

React.render(<App />, document.getElementById('app'));


  • value String the markdown
  • options Object (newValue) options passed to the CodeMirror instance
  • onChange Function (newValue) called when a change is made
