    How it works
    1. Resolve every linenew URL(line, domain) turns paths like /menu into full addresses. Lines that cannot be parsed are reported.
    2. Clean the listOther domains, duplicates, query strings and blocked paths are removed, and each removal is explained.
    3. Write both filesThe sitemap lists every page with optional date, frequency and priority. robots.txt blocks the paths you chose and points to the sitemap.
    
  
    const base = new URL("https://example.com");
const pages = lines.map((l) => new URL(l, base))
  .filter((u) => u.host === base.host);

const xml = `<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
${pages.map((u) => `  <url><loc>${u.href}</loc><lastmod>${today}</lastmod></url>`).join("\n")}
</urlset>`;
const robots = `User-agent: *\nDisallow: /admin\n\nSitemap: ${base.origin}/sitemap.xml`;
