How to delete all files in a firebase storage directory

Question

I have a firebase storage path that looks like this.

firebase.storage().ref('temp/test')

the "test" folder has about 25-50 files. I know there is not a way to delete the whole directory in firebase but Is there a way to iterate through all the files in a directory and deleting them one by one?

Yes, you can use the listAll() method, as follows:

  const storageRef = firebase.storage().ref('temp');
  storageRef.listAll().then((listResults) => {
    const promises = listResults.items.map((item) => {
      return item.delete();
    });
    Promise.all(promises);
  });

Note that:

1. This method is only available for Firebase Rules Version 2 (add rules_version = '2'; at the top of the Security Rules).
2. This is a helper method for calling list() repeatedly until there are no more results. The default pagination size is 1000.
