next-sitemap FAQ
How do I generate sitemaps after building?
Add "postbuild": "next-sitemap" to package scripts and run it after "next build" with a next-sitemap.config.js file in the project root.
Can I use a different config file?
Yes. Pass the path with --config, for example "next-sitemap --config awesome.config.js".
How do I split a large sitemap?
Set sitemapSize in the config; when URLs exceed that number, files like sitemap-0.xml, sitemap-1.xml and an index sitemap.xml are created.
