This fork contains some enhancements to the react-md-editor:

  • Enhanced ALL default command buttons (e.g. bold, italic, list) to match Github behavior (e.g. include remove feature)
  • Added table, mention, issue, help commands
  • Added Ctrl+D to duplicate line/lines
  • Added Alt+UpArrow/DownArrow to move line/lines

A simple markdown editor with preview, implemented with React.js and TypeScript. This React Component aims to provide a simple Markdown editor with syntax highlighting support. This is based on textarea encapsulation, so it does not depend on any modern code editors such as Acs, CodeMirror, Monaco etc.

Features

  • 📑 Indent line or selected text by pressing tab key, with customizable indentation.
  • ♻️ Based on textarea encapsulation, does not depend on any modern code editors.
  • 🚧 Does not depend on the uiw component library.
  • 🚘 Automatic list on new lines.
  • 😻 GitHub flavored markdown support.
  • 🌒 Support dark-mode/night-mode @v3.11.0+.
  • 💡 Support next.js, Use examples in next.js.

Quick Start

npm i @uiw/react-md-editor

Using

Open in CodeSandbox Open in Github gh-pages Open in Gitee gh-pages

import React from "react";
import MDEditor from '@uiw/react-md-editor';

export default function App() {
  const [value, setValue] = React.useState("**Hello world!!!**");
  return (
    <div className="container">
      <MDEditor
        value={value}
        onChange={setValue}
      />
      <MDEditor.Markdown source={value} style={{ whiteSpace: 'pre-wrap' }} />
    </div>
  );
}

Special Markdown syntax

Supports for CSS Style

Use HTML comments <!--rehype:xxx--> to let Markdown support style customization.

## Title
<!--rehype:style=display: flex; height: 230px; align-items: center; justify-content: center; font-size: 38px;-->

Markdown Supports **Style**<!--rehype:style=color: red;-->

Ignore content display via HTML comments

Shown in GitHub readme, excluded in HTML.

# Hello World

<!--rehype:ignore:start-->Hello World<!--rehype:ignore:end-->

Good!

Output:

<h1>Hello World</h1>

<p>Good!</p>

Security

Please note markdown needs to be sanitized if you do not completely trust your authors. Otherwise, your app is vulnerable to XSS. This can be achieved by adding rehype-sanitize as a plugin.

import React from "react";
import MDEditor from '@uiw/react-md-editor';
import rehypeSanitize from "rehype-sanitize";

export default function App() {
  const [value, setValue] = React.useState(`**Hello world!!!** <IFRAME SRC=\"javascript:javascript:alert(window.origin);\"></IFRAME>`);
  return (
    <div className="container">
      <MDEditor
        value={value}
        onChange={setValue}
        previewOptions={{
          rehypePlugins: [[rehypeSanitize]],
        }}
      />
    </div>
  );
}

Support Nextjs

Use examples in nextjs. #52 #224

Open in CodeSandbox Open in CodeSandbox Open in StackBlitz #52 #224

npm install next-remove-imports
npm install @uiw/react-md-editor@v3.6.0
// next.config.js
const removeImports = require('next-remove-imports')();
module.exports = removeImports({});
import "@uiw/react-md-editor/markdown-editor.css";
import "@uiw/react-markdown-preview/markdown.css";
import dynamic from "next/dynamic";
import { useState } from "react";

const MDEditor = dynamic(
  () => import("@uiw/react-md-editor"),

  const [value, setValue] = useState("**Hello world!!!**");
  return (
    <div>
      <MDEditor value={value} onChange={setValue} />
    </div>
  );
}

export default HomePage;

Support dark-mode/night-mode

By default, the dark-mode is automatically switched according to the system. If you need to switch manually, just set the data-color-mode="dark" parameter for body.

<html data-color-mode="dark">
document.documentElement.setAttribute('data-color-mode', 'dark')
document.documentElement.setAttribute('data-color-mode', 'light')

Inherit custom color variables by adding .wmde-markdown-var selector. Setting theme styles with data-color-mode="light".

<div data-color-mode="light">
  <div className="wmde-markdown-var"> </div>
  <MDEditor source="Hello World!" />
</div>
