I understand that you want to derive the bucket and file names from a downloadURL.

If you look at the format of a downloadURL you will find that it is composed as follows:

https://firebasestorage.googleapis.com/v0/b/<your-project-id>.appspot.com/o/<your-bucket-name>%2F<your-file-name>?alt=media&token=<a-token-string>

So you just need to use a set of Javascript methods like indexOf(), substring() and/or slice() to extract the bucket and file names from the downloadURL.

Then you could do something like the following, according to https://cloud.google.com/nodejs/docs/reference/storage/2.0.x/File:

const {Storage} = require('@google-cloud/storage');

const storage = new Storage();

const bucket = storage.bucket('<your-bucket-name>');



const file = bucket.file('<your-file-name>');
