10. Use expressive-code for enriching code blocks progressively

Accepted

Context

Code blocks should have certain ergonomics.

But these need to be done in a way that is progressive. Any enhancements should be ignored by markdown-processors I don’t control (dev.to, Notion, StackOverflow, GitHub, etc.) This ensures that visitors to my site get a great experience but snippets don’t have to re-formatted to be useful elsewhere.

The Astro docs use expressive-code, which supports shiki. It currently provides two discrete plug-ins that allow me to do everything stated above.

You can find examples of my intended use-cases at chan.dev/styleguide/post.

Decision

Use expressive-code via the first-class Astro integration.

Consequences

Tailwind prose needs additional styles to make figure > code look like code.
