Astro: @astrojs/mdx@4.2.0 Release

Minor Changes

• #13352 cb886dc Thanks @delucis! - Adds support for a new experimental.headingIdCompat flag

  By default, Astro removes a trailing - from the end of IDs it generates for headings ending with special characters. This differs from the behavior of common Markdown processors.

  You can now disable this behavior with a new configuration flag:

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    experimental: {
      headingIdCompat: true,
    },
  });
  

  This can be useful when heading IDs and anchor links need to behave consistently across your site and other platforms such as GitHub and npm.

  If you are using the rehypeHeadingIds plugin directly, you can also pass this new option:

  // astro.config.mjs
  import { defineConfig } from 'astro/config';
  import { rehypeHeadingIds } from '@astrojs/markdown-remark';
  import { otherPluginThatReliesOnHeadingIDs } from 'some/plugin/source';
  
  export default defineConfig({
    markdown: {
      rehypePlugins: [
        [rehypeHeadingIds, { experimentalHeadingIdCompat: true }],
        otherPluginThatReliesOnHeadingIDs,
      ],
    },
  });
