netlify_builder preset not working as expected (Netlify returning 405)

[Stiropor]

Environment

When building on Netlify:
node: 20.x
nitro: 2.10.4

Reproduction

https://stackblitz.com/edit/github-dlgsurlp-kv8uscif?file=server%2Froutes%2Findex.ts,server%2Fapi%2Ftest.post.ts

Github repo:
https://github.com/EngageFactory/nitro-swr-test

Describe the bug

When building on Netlify with netlify_builder preset ignores the swr setting

  routeRules: {
    '/api/**': { cache: false, swr: false },
  },

works in stackblitz but not on Netlify. It should build the api routes with normal netlify preset (understanding from nuxt/nuxt#19774 (comment)), otherwise netlify accepts GET only (https://docs.netlify.com/configure-builds/on-demand-builders/).
Netlify returns 405 method not allowed

Posting here as adviced by @danielroe on nuxt/nuxt#19774 where similar problem is being addressed.

Thanks for detailed issue.

Please consider using main netlify preset.

As of 2.10.0 release Nitro supports functions v2 format and automatically adds durable cache-control which is the new recommended approach from Netlify.

(we might update docs. /cc @serhalp)

Thanks @pi0 this worked exactly as we wanted, speed is now 500ms -> 50ms also API endpoints work as they should!

But if I understand correctly then netlify_builder is not even needed anymore, meaning this preset is then obsolete? I sugges it's then removed from docs (also Nuxt) to avoid confusion and errors.

[pi0]

Yes we should do it from docs at least 👍🏼

[Stiropor]

Do I close the issue or do you need it for docs?

[serhalp]

Yes I had originally removed the netlify_builder preset entirely in #2406 but we pulled that out of the PR to keep it non-breaking.

@pi0 can we remove it in v3?

[pi0]

Yes we can drop it in v3 for sure.

For v2, removing preset would be a breaking change but i suggest use docs + a preset level warning to make people moving away from it. (if you have time to make a PR i would appreciate 🙏
