MDX Superpowers: A Living, Interactive Blog Post
MDX lets you write markdown while sprinkling in real React components. That means one file can mix narrative, code, data, and interaction.
This post is 100% MDX. Everything below — graphs, buttons, tables, images — lives in a single index.mdx file.
1) Interactive graphs
A signal you can reshape
Signal Explorer
Tune the sliders to reshape the curve.
A bar chart driven by state
Composable Bar Chart
Buttons drive a live re-render of the data array.
2) Executable actions inside your prose
Executable Actions
Tick tasks, then execute a mini workflow right in MDX.
Execution log
No runs yet.
You can even embed smaller widgets inline, like a counter that sits right inside the flow:

3) Rich markdown + JSX composition
MDX supports GitHub-flavored markdown features out of the box:
- Task lists
- Tables
- Strikethrough
- Autolinked headings
A data table as a component
Embedding real Next.js components
Here is a Next Image component rendered right inside MDX:
A collapsible section with HTML
Click to expand: how the line chart is built
It is just an SVG path whose points are generated from a sine wave in React state.
The sliders tweak amplitude, frequency, and noise, and MDX re-renders the component.
4) Code blocks with syntax highlighting
export function MyCard({ title }: { title: string }) {
return (
<div className="rounded-lg border p-4">
<h3>{title}</h3>
<p>MDX lets this live right next to markdown.</p>
</div>
);
}5) Why this is powerful
MDX turns a blog post into a product surface:
- Teach concepts with live, modifiable visuals
- Embed interactive demos next to explanations
- Ship reusable, styled components for authors
If you want, I can add more components (tabs, playgrounds, data fetchers) or tailor this to a specific topic.
