Accessing older versions of a file with a Cloud function within Firebase

I enabled versioning and accessed versions of a single json file using gsutil on a Firebase storage bucket. I am now searching how to retreive versions of that file using cloud functions and eventually allow users to get back an older version of their work if needed. I did not find any documentation on how to list versions of a file with a cloud function. Is that possible? Thank you!

From within Cloud Functions you'll access Cloud Storage through the Firebase Admin SDK for Node.js, which contains a very thin wrapper around the regular Node.js SDK for Cloud Storage.

It looks like you can pass in a versions parameter to the getFiles method.

It should be something like:

const result = await bucket.getFiles({ versions: true })
result.files.forEach(file => {
  console.log(file.name);
});
