I would like to use storage service from Firebase with a nodeJS api (hosted on "firebase functions") to allow the users to upload his avatars.

So I read the doc from https://firebase.google.com/docs/storage/web/start

and I do:

admin.js

const admin = require('firebase-admin');

const config = require('./config.js');



admin.initializeApp(config);



const db = admin.firestore();

const storage = admin.storage();



module.exports = { admin, db, storage };

user.js

const { admin, db, storage } = require('../util/admin');



exports.postAvatar = async (request, response) => {



  const storageRef = storage.ref();



}

but I have the following error: storage.ref is not a function

Is something is missing from the documentation ?

The console.log of storage const is:

Storage {

  INTERNAL: StorageInternals {},

  storageClient: Storage {...},

  appInternal: FirebaseApp {...}

}
