help: generate dynamic sitemap and include external sitemap

[gsabater]

📚 What are you trying to do?

Hello,

i would like to create a new sitemap merging the current project routes and an external sitemap from an api.

🔍 What have you tried?

I’m using Nuxt Sitemap to generate a list of URLs with the crawler module, and it's working as expected with the following configuration:

sitemap: {
  enabled: true,
  exclude: ['/tabler*', '/account/**', '/dev/**'],
  cacheMaxAgeSeconds: 3600 * 24,
}

However, I want to include a large and expensive sitemap from an API, which contains over 40,000 game links. I’ve partially achieved this by adding the API URL as a source. Even though the URL is .xml, the data is dynamically loaded from the database:

sources: [
  'https://api.backlog.rip/sitemap.xml',
]

Finally, during the build process, I want to generate a static sitemap.xml file that merges the crawled URLs with the external API URLs so that the application no longer queries the API at runtime.

I’ve tried consulting GPT, reviewing the documentation, and checking GitHub issues, but I haven’t been able to find a definitive solution. I’ve experimented with several approaches, but I’m unsure if this is achievable with the current setup.

Thanks for your time and any guidance you can provide!
