Playground
Component
Playground component lets you write Nextra-compatible MDX that renders only on the client. It's modeled after the functionality found in MDX Playground (opens in a new tab).
In some instances where remote loading MDX is not an option, this may work as a great alternative.
Here's an example of a code block.
console.log("Hello world, this is a playground component!");
Caveats
Due to the purely client-side nature of this component, features "Table of Contents" and "Front matter" will not work.
