The <Code> component renders syntax highlighted code. It is useful when using a Markdown code block is not possible, for example, to render data coming from external sources like files, databases, or APIs.

console.log('This could come from a file or CMS!');

Display imported code

In MDX files and Astro components, use Vite’s ?raw import suffix to import any code file as a string. You can then pass this imported string to the <Code> component to include it on your page.

src/content/docs/example.mdx

import { Code } from '@astrojs/starlight/components';
import importedCode from '/src/env.d.ts?raw';

<Code code={importedCode} lang="ts" title="src/env.d.ts" />
