v4.4.0

This release includes a few fixes for frontmatter types, as well as a way to provide a frontmatter type to serialize or compileMDX and have it propagate through to the returned frontmatter property. See the documentation for an example.

serialize:

import { serialize } from 'next-mdx-remote/serialize'

interface Frontmatter {
  title: string
  published: string
  description?: string
}

//     👇 should have type Frontmatter
const { frontmatter } = serialize<Record<string, unknown>, Frontmatter>(source)

compileMDX:

import { compileMDX } from 'next-mdx-remote/rsc'

interface Frontmatter {
  title: string
  published: string
  description?: string
}

export default async function Page({ source }) {
	//              👇 should have type Frontmatter
	const { content, frontmatter } = await compileMDX<Frontmatter>(source)

	return (
		<>
			<h1>{frontmatter.title}</h1>
			{content}
		</>
	)
}

v4.3.0 - Server Components Support (experimental)

next-mdx-remote now has experimental support for React Server Components! 🎉 Access the new API by importing from next-mdx-remote/rsc, and head to the documentation for usage instructions and additional examples.

import { MDXRemote } from 'next-mdx-remote/rsc'

export default async function Page() {
  const mdxSource = await getContent()

  return (
    <MDXRemote source={mdxSource} />
  )
}

v4.0.0

next-mdx-remote has been upgraded to use MDX v2 under the hood, which comes with improved performance and a whole list of other enhancements. Due to the improved code generated from MDX, we've also been able to remove our usage of esbuild. If you're using Next v12, no changes should be required to upgrade! Users on Next v11.1 might need to set experimental: { esmExternals: true } in next.config.js.

Note that some of the underlying changes in MDX v2 may require you to adjust some of your MDX content or custom components.

Take it for a spin and let us know if you run into any issues. 🙏

$ npm install next-mdx-remote@latest

Breaking Changes

• Exposes ESM
• Upgrade to MDX v2 under the hood, see the blog post for more information
• Remove esbuild integration

Features

• Optional frontmatter parsing by passing { parseFrontmatter: true } to serialize(). Frontmatter is then available in your MDX:

  # {frontmatter.page_title}
  
  Hello world!

• Improved error messages when MDX fails to compile:
