Vite plugin to use MDX with your Vite app.

Features:

• Works with MDX v1 and MDX v2.
• Works with React and Preact.
• Works with Vue [WIP].
• HMR support.
• SSR support.
• Plugin support, such as remark-frontmatter.

1. Install:

   1. Vite Plugin:

       npm install vite-plugin-mdx

   2. MDX v1:

      npm install @mdx-js/mdx

      Or MDX v2:

      npm install @mdx-js/mdx@next

   3. MDX React:

      npm install @mdx-js/react

      Or MDX Preact:

      npm install @mdx-js/preact

2. Add the plugin to your vite.config.js.

   // vite.config.js
   
   import mdx from 'vite-plugin-mdx'
   
   // `options` are passed to `@mdx-js/mdx`
   const options = {
     // See https://mdxjs.com/advanced/plugins
     remarkPlugins: [
       // E.g. `remark-frontmatter`
     ],
     rehypePlugins: [],
   }
   
   export default {
     plugins: [mdx(options)]
   }

3. You can now write .mdx files.

   // hello.mdx
   
   import { Counter } from './Counter.jsx'
   
   # Hello
   
   This text is written in Markdown.
   
   MDX allows Rich React components to be used directly in Markdown: <Counter/>
   

   // Counter.jsx
   
   import React, { useState } from 'react'
   
   export { Counter }
   
   function Counter() {
     const [count, setCount] = useState(0)
   
     return (
       <button onClick={() => setCount((count) => count + 1)}>
         Counter: {count}
       </button>
     )
   }

• React example.
• Preact example.

To define options a per-file basis, you can pass a function to the mdx plugin factory.

mdx((filename) => {
  // Any options passed to `mdx` can be returned.
  return {
    remarkPlugins: [
      // Enable a plugin based on the current file.
      /\/components\//.test(filename) && someRemarkPlugin,
    ]
  }
})

To embed an .mdx or .md file into another, you can import it without naming its export. The file extension is required. Remark plugins are applied to the imported file before it's embedded.

import '../foo/bar.mdx'
