Rendering code cleanly in articles

Articles can include normal Markdown content and code. Highlighting runs at build time, not in the browser.

export function total(items) {
  return items.reduce((sum, item) => sum + item.amount, 0);
}

Shell examples remain readable too.

npm run build
npm run dev

Diff examples are prepared as well.

+export const status = "published";
-export const status = "draft";
