webpack loader for MDX.

Contents

What is this?

This package is a webpack loader to support MDX.

When should I use this?

This integration is useful if you’re using webpack (or another tool that uses webpack, such as Next.js).

This integration can be combined with the Babel loader to compile modern JavaScript features to ones your users support.

If you want to evaluate MDX code then the lower-level compiler (@mdx-js/mdx) can be used manually.

Install

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

npm install @mdx-js/loader

Use

Add something along these lines to your webpack.config.js:

/** @type {import('webpack').Configuration} */
const webpackConfig = {
  module: {
    // …
    rules: [
      // …
      {
        test: /\.mdx?$/,
        use: [
          {
            loader: '@mdx-js/loader',
            /** @type {import('@mdx-js/loader').Options} */
            options: {/* jsxImportSource: …, otherOptions… */}
          }
        ]
      }
    ]
  }
}

export default webpackConfig

See also ¶ Next.js and ¶ Vue CLI, if you’re using webpack through them, for more info.

API

This package exports no identifiers. The default export is mdx.

mdx

This package exports a webpack plugin as the default export. Configuration (see Options) are passed separately through webpack.

Options

Configuration (TypeScript type).

Options are the same as CompileOptions from @mdx-js/mdx with the exception that the SourceMapGenerator and development options are supported based on how you configure webpack. You cannot pass them manually.

Examples

Combine with Babel

If you use modern JavaScript features you might want to use Babel through babel-loader to compile to code that works in older browsers:

/** @type {import('webpack').Configuration} */
const webpackConfig = {
  module: {
    // …
    rules: [
      // …
      {
        test: /\.mdx?$/,
        use: [
          // Note that Webpack runs right-to-left: `@mdx-js/loader` is used first, then
          // `babel-loader`.
          {loader: 'babel-loader', options: {}},
          {
            loader: '@mdx-js/loader',
            /** @type {import('@mdx-js/loader').Options} */
            options: {}
          }
        ]
      }
    ]
  }
}

export default webpackConfig

Types

This package is fully typed with TypeScript. It exports the additional type Options. See § Types on our website for information.

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, @mdx-js/loader@^3, compatible with Node.js 16.
