micromark extensions to support MDX, unaware of JavaScript.

Contents

What is this?

This package contains an extension that adds support for the syntax enabled by MDX to micromark. This extension is used inside MDX. It supports expressions, JSX, and turns some markdown features off. It is not aware of the syntax of JavaScript inside expressions and does not support export/imports.

When to use this

You can use this extension when you are working with micromark.

This project is useful when you want to support MDX, unaware of JavaScript, for example because expressions can include Rust or variables or whatnot. If you want to be aware of JavaScript, use micromark-extension-mdxjs.

Alternatively, you can also use the underlying syntax extensions separately:

When you need a syntax tree, combine this package with mdast-util-mdx.

All these packages are used in remark-mdx, which focusses on making it easier to transform content by abstracting these internals away.

Install

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

npm install micromark-extension-mdx

In Deno with esm.sh:

import {mdx} from 'https://esm.sh/micromark-extension-mdx@2'

In browsers with esm.sh:

<script type="module">
  import {mdx} from 'https://esm.sh/micromark-extension-mdx@2?bundle'
</script>

Use

import {micromark} from 'micromark'
import {mdx} from 'micromark-extension-mdx'

const output = micromark('a <b /> c {1 + 1} d', {extensions: [mdx()]})

console.log(output)

Yields:

<p>a  c  d</p>

…which is useless: go to a syntax tree with mdast-util-from-markdown and mdast-util-mdx instead.

API

This package exports the identifier mdx. There is no default export.

The separate extensions support the development condition. Run node --conditions development module.js to get instrumented dev code. Without this condition, production code is loaded.

mdx()

Create an extension for micromark to enable MDX syntax, unaware of JavaScript.

Returns

Extension for micromark that can be passed in extensions to enable MDX syntax, unaware of JavaScript (Extension).

Authoring

For recommendations on how to author MDX, see each corresponding readme:

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

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

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, micromark-extension-mdx@^2, compatible with Node.js 16.

This package works with micromark version 3 and later.

Security

This package is safe.
