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.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install @mdx-js/react

yarn:

yarn add @mdx-js/react

Use

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

const components = {
  em: props => <i {...props} />
}

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

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

-<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.

API

This package exports the following identifiers: MDXContext, MDXProvider, useMDXComponents, and withMDXComponents. There is no default export.

MDXProvider(props?)

Provider for MDX context.

props

Configuration (Object, optional).

props.components

Mapping of names for JSX components to React components (Record<string, string|Component|Components>, optional).

props.disableParentContext

Turn off outer component context (boolean, default: false).

props.children

Children (JSX elements, optional).

Returns

JSX element.

useMDXComponents(components?)

Get current components from the MDX Context.

components

Additional components (Components) to use or a function that takes the current components and filters/merges/changes them ((currentComponents: Components) => Components).

Returns

Components.

MDXContext

🪦 Deprecated: This export is not recommended for use as it exposes internals which should be hidden. It might be removed in a future major release. Please use useMDXComponents to get context based components and MDXProvider to set context based components instead.

The React Context for MDX (React.Context).

withMDXComponents(Component)

🪦 Deprecated: This export is not recommended for use. It might be removed in a future major release. Please use useMDXComponents to get context based components instead.

Create a HOC of Components which is given the current context based MDX components.

Types

This package is fully typed with TypeScript.

To enable types for imported .mdx, .md, etcetera files, you should make sure the TypeScript JSX namespace is typed. This is done by installing and using the types of your framework, such as @types/react. Then you can install and use @types/mdx, which adds types to import statements of supported files.
