## Getting Started

### Installation

## API Reference

### compile()

### hastToHtml()`;

depth limit करें

import { compile, toc } from "@unifast/node";

const result = compile(md, {
  plugins: [toc({ maxDepth: 2 })],
});

console.log(result.toc);

const result = compile(md, { plugins: [toc()] });

function TableOfContents() {
  return (
    <nav>
      <ul>
        {result.toc.map((entry) => (
          <li key={entry.slug} style={{ marginLeft: (entry.depth - 1) * 16 }}>
            <a href={`#${entry.slug}`}>{entry.text}</a>
          </li>
        ))}
      </ul>
    </nav>
  );
