@mdx-js/preact
Preact context for MDX.
Contents
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 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/preact
yarn:
yarn add @mdx-js/preact
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'`.
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 ¶ Preact in § Getting started for how to get started with MDX and Preact. See ¶ MDX provider in § Using MDX for how to use an MDX provider.
