Advanced MDX support for Next.js

Adds support for MDX with advanced syntax features in Next.js applications

This library wraps the official Next.js + MDX plugin and configures it with additional Remark and Rehype plugins to enable advanced Markdown syntax and make MDX easier to use for our specific use-cases.

Features

• Adds support for YAML frontmatter
  • Automatically adds createdAt and modifiedAt frontmatter fields. Useful for populating <meta> tags for SEO and social media.
  • Adds support for a layout frontmatter field, which can be used to customize the React layout component to use for each MDX page.

• Passes a markdown boolean to React components to indicate whether they originally came from Markdown syntax. This allows you to distinguish between **bold** and <b>bold</b> which can be used to apply different styling, or even render completely different JSX.

• Rewrites links to MDX files (e.g. /pages/docs/some-page.mdx becomes /pages/docs/some-page)

• Detects broken links to MDX files

Usage

Install the library via npm:

npm install @jsdevtools/next-mdx

Then use it in your next.config.js file:

const nextMDX = require("@jsdevtools/next-mdx");

const withMDX = nextMDX({
  // Next-MDX options go here
  siteURL: "http://example.com"
});

module.exports = withMDX({
  // Next.js options go here
  pageExtensions: ["tsx", "mdx"],
});

Options

See options.ts for all of the options that you can pass to Next-MDX.

NOTE: Don’t confuse the Next-MDX options with the Next.js options. Refer to the code example above to see where each goes.
