A markdown editor with preview, implemented with React.js and TypeScript.
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.
textarea encapsulation, does not depend on any modern code editors.uiw component library.npm i @uiw/react-md-editor
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>
);
}
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>
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>
);
}

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!" />
