// import react, react-markdown-editor-lite, and a markdown parser you like
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import MarkdownIt from 'markdown-it';
import MdEditor from 'react-markdown-editor-lite';
// import style manually
import 'react-markdown-editor-lite/lib/index.css';

// Register plugins if required
// MdEditor.use(YOUR_PLUGINS_HERE);

// Initialize a markdown parser
const mdParser = new MarkdownIt(/* Markdown-it options */);

// Finish!
function handleEditorChange({ html, text }) {
  console.log('handleEditorChange', html, text);
}
export default props => {
  return (
    <MdEditor style={{ height: '500px' }} renderHTML={text => mdParser.render(text)} onChange={handleEditorChange} />
  );
};

## Usage in server-side render

If you are using a server-side render framework, like Next.js, Gatsby, please use client-side render for this editor.

For example, Next.js has [next/dynamic](https://nextjs.org/docs/advanced-features/dynamic-import), Gatsby has [loadable-components](https://www.gatsbyjs.org/docs/using-client-side-only-packages/#workaround-3-load-client-side-dependent-components-with-loadable-components)

Following is a example for Next.js:

```js
import dynamic from 'next/dynamic';
import 'react-markdown-editor-lite/lib/index.css';

const MdEditor = dynamic(() => import('react-markdown-editor-lite'), {
  ssr: false,
});

export default function() {
  return <MdEditor style={{ height: '500px' }} renderHTML={/* Render function */} />;
}
```

With plugins:

```js
import dynamic from 'next/dynamic';
import 'react-markdown-editor-lite/lib/index.css';

const MdEditor = dynamic(
  () => {
    return new Promise(resolve => {
      Promise.all([
        import('react-markdown-editor-lite'),
        import('./my-plugin'),
        /** Add more plugins, and use below */
      ]).then(res => {
        res[0].default.use(res[1].default);
        resolve(res[0].default);
      });
    });
  },
  {
    ssr: false,
  },
);

export default function() {
  return <MdEditor style={{ height: '500px' }} renderHTML={/* Render function */} />;
}
```

Full example see [here](https://codesandbox.io/s/next-js-80bne)

## Import in Browser

Since 1.1.0, You can add `script` and `link` tags in your browser and use the global variable `ReactMarkdownEditorLite`.

You can download these files directly from [![cdnjs][cdnjs-image]][cdnjs-url] [![jsdelivr][jsdelivr-image]][jsdelivr-url] [![unpkg][unpkg-image]][unpkg-url]

Note: you should import react before `ReactMarkdownEditorLite`.

For example, in webpack, you import ReactMarkdownEditorLite by `script` tag in your page, and write webpack config like this:

```js
externals: {
  react: 'React',
  'react-markdown-editor-lite': 'ReactMarkdownEditorLite'
}
```
