What is this?

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

When should I use this?

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

Install

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

npm install @mdx-js/preact

In Deno with esm.shesmsh:

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

In browsers with esm.shesmsh:

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

Use

import {MDXProvider} from '@mdx-js/preact'
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/preact'`.

/** @type {import('mdx/types.js').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:

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

See ¶ Preact in § Getting startedstart-preact for how to get started with MDX and Preact. See ¶ MDX provider in § Using MDXuse-provider for how to use an MDX provider.

Types

This package is fully typed with TypeScript. It exports the additional types MergeComponentsapi-merge-components and Propsapi-props.
For types to work, make sure the TypeScript JSX namespace is typed. This is done by installing and using the types of your framework, as in preact.

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/preact@^3, compatible with Node.js 16.
