@mdx-js/react

What is @mdx-js/react?

The @mdx-js/react package allows you to use MDX (Markdown for the component era) with React. MDX is a syntax that lets you seamlessly use JSX in your markdown documents. You can import components, such as interactive charts or alerts, and export metadata. This makes writing long-form content with React components a breeze.

What are @mdx-js/react's main functionalities?

Embedding JSX in Markdown

Allows embedding JSX directly in your markdown files, enabling the inclusion of React components within the content.

<MDXProvider><MyDocument /></MDXProvider>

Importing and using components in MDX

Enables the import and use of React components directly in MDX files, making it easy to integrate interactive or custom elements in markdown content.

import { Chart } from './components/Chart'

# My MDX document

Here's a chart component in my MDX document:

<Chart />

Using MDXProvider to customize components

Allows customization of standard markdown elements (like headings, paragraphs) with your own React components, providing a way to apply consistent styling or behavior across all markdown content.

import { MDXProvider } from '@mdx-js/react'
import { MyHeading, MyParagraph } from './MyComponents'

const components = {
  h1: MyHeading,
  p: MyParagraph
}

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

Other packages similar to @mdx-js/react

remark-react

Similar to @mdx-js/react, remark-react allows you to render markdown as React components. However, it uses the remark parsing library and does not support the direct use of JSX within markdown.

react-markdown

react-markdown is another library that lets you render markdown content as React components. It supports plugins to extend its functionality but, unlike @mdx-js/react, does not allow for the embedding of JSX components directly within the markdown.

markdown-to-jsx

markdown-to-jsx compiles markdown into JSX but is more focused on simplicity and performance. It doesn't offer the same level of integration with React components or the ability to import and use components directly in markdown files as @mdx-js/react does.

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.
