Tips

Integration with Syntax Highlighters

This component works great with syntax highlighting libraries like react-syntax-highlighter or prism-react-renderer. Simply wrap the code content with your preferred highlighter:

import { Prism as SyntaxHighlighter } from 'react-syntax-highlighter';
import { oneDark } from 'react-syntax-highlighter/dist/esm/styles/prism';
 
<CodeBlock language="javascript">
  <SyntaxHighlighter language="javascript" style={oneDark}>
    {code}
  </SyntaxHighlighter>
</CodeBlock>

Custom Styling

Override the default styles using Tailwind classes:

<CodeBlock 
  className="border-blue-500 bg-blue-950" 
  language="python"
>
  {code}
</CodeBlock>
