How do I get the default bucket name in Firebase, from inside Node.js?

Question

I want to avoid hard coding the default bucket name in a Firebase project. How do I get it on server side?

const admin = require("firebase-admin");
const defaultBucket = admin.storage().bucket();
const defaultBucketName = ...?

Answer 1

Get bucket name:

const defaultBucketName = defaultBucket.name;

Ref: Interface: ObjectMetadata

Answer 2

It turns out that the information is stored in an environment variable but not imported into the admin tooling directly. So the best way I have found to prepare your environment to serve the default bucket name is as follows:

const firebaseConfig = JSON.parse(process.env.FIREBASE_CONFIG!);

admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  storageBucket: firebaseConfig.storageBucket,
});
