A simple yet powerful and extensible Markdown Editor editor for React. React-mde has no 3rd party dependencies. Min + Gzipped package is around 15KB.

React-mde is used in another tool I made, 🌐



npm i react-mde

Markdown Preview

React-mde is agnostic regarding how to preview Markdown. The examples will use Showdown

npm install showdown


React-mde is a completely controlled component.

Minimal example using Showdown:

import * as React from "react";
import ReactMde from "react-mde";
import * as Showdown from "showdown";
import "react-mde/lib/styles/css/react-mde-all.css";

export default class App extends React.Component {
  constructor (props) {
    this.state = {
      value: "**Hello world!!!**"
    this.converter = new Showdown.Converter({
      tables: true,
      simplifiedAutoLink: true,
      strikethrough: true,
      tasklists: true

  handleValueChange = (value) => {
    this.setState({ value });

  render () {
    return (
      <div className="container">
          generateMarkdownPreview={markdown =>

Customizing Icons

React-mde comes with SVG icons extracted from FontAwesome included.

You can customize the way icons are resolved by passing your own getIcon that will return a ReactNode given a command name.

    getIcon={(commandName) => <MyCustomIcon name={commandName} />}
    // ...

React-mde Props

The types are described below

  • value: string: The Markdown value.
  • onChange: (value: string): Event handler for the onChange event.
  • selectedTab: "write" | "preview": The currently selected tab.
  • onTabChange: (tab) => void: Function called when the selected tab changes.
  • className?: string: Optional class name to be added to the top level element.
  • commands?: CommandGroup[]: An array of CommandGroup, which, each one, contain a commands property (array of Command). If no commands are specified, the default will be used. Commands are explained in more details below.
  • generateMarkdownPreview: (markdown: string) => Promise;: Function that should return the generated HTML for the preview. If this prop is falsy, then no preview is going to be generated.
  • getIcon?: (commandName: string) => React.ReactNode } An optional set of button content options, including an iconProvider to allow custom icon rendering. options. It is recommended to inspect the layouts source code to see what options can be passed to each while the documentation is not complete.
  • emptyPreviewHtml: What to display in the preview in case there is no markdown.
  • readOnly?: boolean: Flag to render the editor in read-only mode.
  • textAreaProps: Extra props to be passed to the textarea component.
  • l18n: A localization option. It contains the strings write and preview.
  • minEditorHeight (number): The minimum height of the editor.
  • maxEditorHeight (number): The max height of the editor (after that, it will scroll).
  • minPreviewHeight (number): The minimum height of the preview.


The following styles from React-mde should be added: (Both .scss and .css files are available. No need to use sass-loader if you don't want)

Easiest way: import react-mde-all.css:

import 'react-mde/lib/styles/css/react-mde-all.css';

If you want to have a more granular control over the styles, you can import each individual file.

If you're using SASS, you can override these variables:

XSS concerns

React-mde does not automatically sanitize the HTML preview. If your using Showdown, this has been taken from their documentation:

Cross-side scripting is a well known technique to gain access to private information of the users of a website. The attacker injects spurious HTML content (a script) on the web page which will read the user’s cookies and do something bad with it (like steal credentials). As a countermeasure, you should filter any suspicious content coming from user input. Showdown doesn’t include an XSS filter, so you must provide your own. But be careful in how you do it…

You might want to take a look at showdown-xss-filter.


You can create your own commands or reuse existing commands. The commands property of React-mde expects an array of CommandGroup, which contains an array of commands called commands. You can also import the existing commands as displayed below:

import ReactMde, {commands} from "react-mde";

const listCommands = [
        commands: [


Please refer to the commands source code to understand how they should be implemented.
