Delete a file from firebase storage using download url with Cloud Functions

I have a collection of profiles in my Firestore db and a field named "profilePicture" with a downloadUrl as the value.

Im using cloud functions and been trying for a long time to figure out how to delete the profilePicture when the profile is deleted.

I know how to create a trigger when the profile is deleted and get the profile picture downloadUrl, but how do I delete the file from storage with only the downloadUrl?

Solution

  • My understanding is that the node SDK for Cloud Storage can't convert HTTP URLs into file paths within a storage bucket. Instead, you should be storing the file path along with the download URL in document. This will make it possible for to build a File object that can be used to delete the image when it's time to do so.
