Interactive posts with MDX
- mdx
- demo
This post is written in MDX, so it can mix Markdown with real components. The widget below is a Preact island — it ships no JavaScript until it scrolls into view, then hydrates and becomes interactive.

Everything around it is still plain Markdown: lists, code, and links all work
as usual.
Why this is nice
- Content stays readable and easy to write.
- Interactivity is opt-in and cheap — only islands hydrate.
- You can drop real demos (charts, playgrounds, visualizations) right into a post.
Regular .md posts keep working too; reach for .mdx only when a post needs a
component.
