Sitemap — a new XML sitemap module with sitemap index, IndexNow, and an admin dashboard

[maximus]

I've been working on sites where the standard sitemap setup started showing cracks: XML generated on every request eating memory, no way to regenerate automatically without writing custom hooks, and no visibility into what actually ended up in the file.

So I built Sitemap — a module that generates static XML files to disk, splits output by template name, and handles the full lifecycle from generation to search engine notification.

What it does differently:

• Writes files to disk instead of rendering in memory — no RAM spike on large sites
• Pages are fetched in chunks of 500 with uncacheAll(), so memory stays flat regardless of page count
• Each template gets its own named file: sitemap-product.xml, sitemap-blog.xml, etc. — the index at sitemap.xml references them all
• Auto-regeneration via LazyCron with a configurable interval; the LazyCron hook slot is chosen dynamically to match what you configured (every hour, every 6 hours, daily, etc.) rather than always using everyHour
• A needs_regen flag is set whenever a page is saved, trashed, or deleted — visible in the admin dashboard
• IndexNow support: after generation, all URLs are submitted to api.indexnow.org in batches of 10,000
• Sitemap: directive written directly to the physical robots.txt on save and on generate
• Lock file prevents concurrent generation
• Admin dashboard at Setup > Sitemap showing file count, URL count, total size, and last generated time

Settings stored in a dedicated DB table (sitemap_settings, name/value, MEDIUMTEXT) rather than the module's data field — avoids the serialized config size limit when template settings grow large.

Image sitemap extension and hreflang alternate links for multilanguage sites are both supported.

Still v1.0.0, so feedback is very welcome — especially from anyone running it on a site with 10k+ pages.
