How to deploy Firebase Hosting?

i have these firebase.json

{
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "functions": {
    "source": ".output/server",
    "runtime": "nodejs16"
  },
  "hosting": {
    "public": ".output/public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

λ firebase deploy

=== Deploying to 'project-79XXX'...

i  deploying firestore, functions, hosting
i  firestore: reading indexes from firestore.indexes.json...
i  cloud.firestore: checking firestore.rules for compilation errors...
+  cloud.firestore: rules file firestore.rules compiled successfully

Error: There was an error reading .output\server\package.json:

 .output\server\index.js does not exist, can't deploy Cloud Functions

Any example would be better.

There are lots of other deployment targets other than firebase. See https://nitro.unjs.io/guide/presets.html.

Yes, firebase requires that these are installed, with exception of firebase-functions-test.
