Markdown & MDX Extensibility

Astro provides a powerful pipeline for content. Beyond basic Markdown, you can extend functionality using two types of plugins:

Remark & Rehype

  • Remark: Plugins that transform the Markdown AST (e.g., adding a table of contents).
  • Rehype: Plugins that transform the HTML AST (e.g., adding IDs to headings or lazy-loading images).

MDX

MDX allows you to use Astro components (or framework islands) directly inside your Markdown files, enabling rich interactive content.
