nit: extract this anonymous function to a dedicated function.

The URLs in the sitemap should use .html extensions instead of .md extensions. The api_doc_source field contains paths like "doc/api/test.md", but the actual published documentation uses HTML files. Other generators in the codebase (web, legacy-html, orama-db, jsx-ast) all generate URLs with .html extensions. The path transformation should be: entry.api_doc_source.replace(/^doc//, '/docs/latest/').replace(/.md$/, '.html')

Suggested change
const path = entry.api_doc_source.replace(/^doc\//, '/docs/latest/');
const path = entry.api_doc_source
.replace(/^doc\//, '/docs/latest/')
.replace(/\.md$/, '.html');

nit: all of this could be inlined (all in one line object creation instead of multi line)

loc: url,
lastmod,
changefreq: 'weekly',
priority: '0.8',
};
});

apiPages.push({
loc: new URL('/docs/latest/api/', BASE_URL).href,
lastmod,
changefreq: 'daily',
priority: '1.0',
});

const template = await readFile(
join(import.meta.dirname, 'template.xml'),

nit: use template files for this and then do simple key->value substitution. Or use proper rss/feed libraries OR xml libraries.

You can probably use hast (but I'm also fine with it this way), seeing as the majority of it is a template

<loc>${page.loc}</loc>
<lastmod>${page.lastmod}</lastmod>
<changefreq>${page.changefreq}</changefreq>
<priority>${page.priority}</priority>
</url>
`
)
.join('\n');

const sitemap = template.replace('__URLSET__', urlset);

if (output) {
await writeFile(join(output, 'sitemap.xml'), sitemap, 'utf-8');
}

return sitemap;
},
};
