Support Nextjs

Use examples in nextjs. #52 #224

Open in CodeSandbox

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

const MarkdownEditor = dynamic(
  () => import("@uiw/react-markdown-editor").then((mod) => mod.default),
  { ssr: false }
);

function HomePage() {
  return (
    <div>
      <MarkdownEditor value="Hello Markdown!" />
    </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 html Element.

<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.

const Demo = () => {
  return (
    <div>
      <div className="wmde-markdown-var"> </div>
      <MarkdownEditor value="Hello Markdown!" />
    </div>
  )
}
