Code

How Code Block is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

import { CodeBlock } from "@/components/ui/code-block";

const code = `import { useState } from 'react';

export function Counter() {
  const [count, setCount] = useState(0);

  return (
    <button onClick={() => setCount(count + 1)}>
      Count: {count}
    </button>
  );
}
`;

export default function CodeBlockDemo() {
  return (
    <div className="flex w-full items-center justify-center p-8">
      <CodeBlock
        code={code}
        language="tsx"
        filename="components/counter.tsx"
        highlightLines={[6]}
        className="w-full max-w-xl"
      />
    </div>
  );
}
