we've already moved to merging breaking changes for nuxt v5 onto main, which means it is already possible to test the current state of nuxt v5 by setting:

  {
    "dependencies": {
-    "nuxt": "^4.0.0"
+    "nuxt": "npm:nuxt-nightly@5x"
  }
}

however, note that right now very few of the breaking changes have been merged so please treat this as an early preview.

in particular, it's not possible to test nitro v3 – but expect that to change very soon...
