📚 Description

Resolves #1655

firebase functions gen2 with region specified can be deployed.

manual integration tests

Since there is no integrated test code that includes firebase deploy, I manually performed the following three tests.

1. have region and deploy to firebase.

export default defineNitroConfig({
  firebase: {
    gen: 2,
    nodeVersion: "18",
    httpsOptions: {
      region: "asia-northeast1",
      maxInstances: 3,
    },
  },
});

2. have no httpsOptions configuration and deploy to firebase.

export default defineNitroConfig({
  firebase: {
    gen: 2,
    nodeVersion: "18",
  },
});

3. have no region configuration and deploy to firebase.

export default defineNitroConfig({
  firebase: {
    gen: 2,
    nodeVersion: "18",
    httpsOptions: {
      maxInstances: 3,
    },
  },
});

These three tests passed.

Using Nitro 2.6.3-28220517.4ac686a and setting region in nuxt.config.ts as

nitro: { preset: 'firebase', firebase: { gen: 2, httpsOptions: { region: 'europe-west1' }, serverFunctionName: 'functionname', nodeVersion: '18' } },

Still deploying to 'us-central1'
