Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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. In Node.js (version 16+), install with npm:

npm install @mdx-js/preact

In Deno with esm.sh:

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

In browsers with esm.sh:

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

Use

/**
 * @import {MDXComponents} from 'mdx/types.js'
 */

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 {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 started for how to get started with MDX and Preact. See ¶ MDX provider in § Using MDX for how to use an MDX provider.

API

This package exports the identifiers MDXProvider and useMDXComponents. There is no default export.

MDXProvider(properties?)

Provider for MDX context.

Parameters
  • properties (Props) — configuration
Returns

Element (JSX.Element).

useMDXComponents(components?)

Parameters
Returns

Current components (MDXComponents from mdx/types.js).

MergeComponents

Custom merge function (TypeScript type).

Parameters
Returns

Additional components (MDXComponents from mdx/types.js).

Props

Configuration for MDXProvider (TypeScript type).

Fields

Types

This package is fully typed with TypeScript. It exports the additional types MergeComponents and 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.
