What is this?

This package is a context based components provider for combining React with MDX.

When should I use this?

This package is not needed for MDX to work with React. See ¶ MDX provider in § Using MDX for when and how to use an MDX provider.

If you use Next.do not use this. Add an mdx-components.tsx (in src/ or /) file instead. See Configuring MDX on next.org for more info.

Install

This package is ESM only. In Node. (version 16+)install with npm:

npm install @mdx-/react

In Deno with esm.sh:

import {MDXProvider} from 'https://esm.sh/@mdx-/react@3'

In browsers with esm.sh:

<script type="module">
  import {MDXProvider} from 'https://esm.sh/@mdx-/react@3?bundle'
</script>

Use

/**
 * @import {MDXComponents} from 'mdx/types.'
 */

import {MDXProvider} from '@mdx-/react'
import Post from './post.mdx'
// ^-- Assumes an integration is used to compile MDX to JSsuch as
// `@mdx-/esbuild``@mdx-/loader``@mdx-/node-loader`or
// `@mdx-/rollup`and that it is configured with
// `options.providerImportSource: '@mdx-/react'`.

/** @type {MDXComponents} */
const components = {
  em(properties) {
    return <i {...properties} />
  }
}

console.log(
  <MDXProvider components={components}>
    <Post />
  </MDXProvider>
)

👉 Note: you don’t have to use MDXProvider and can pass components directly:

Diff

-<MDXProvider components={components}>
-  <Post />
-</MDXProvider>
+<Post components={components} />

See ¶ React in § Getting started for how to get started with MDX and React. See ¶ MDX provider in § Using MDX for how to use an MDX provider.

Types

This package is fully typed with TypeScript. It exports the additional types MergeComponents and Props.

For types to workmake sure the TypeScript JSX namespace is typed. This is done by installing and using the types of your frameworkas in @types/react.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node..

When we cut a new major releasewe drop support for unmaintained versions of Node. This means we try to keep the current release line@mdx-/react@^3compatible with Node. 16.
