E.6 Delete Files

Delete Files from Firebase Storage

Of course you can also delete files from Firebase Storage.

Note: By default, Firebase Storage buckets require Firebase Authentication to upload files. You can change your Firebase Storage Security Rules to allow unauthenticated access. Since the default Google App Engine app and Firebase share this bucket, configuring public access may make newly uploaded App Engine files publicly accessible as well. Be sure to restrict access to your Storage bucket again when you set up authentication.

To delete a file, first create a reference. to that file. Then call the delete() method on that reference.

var rootRef:StorageReference = Storage.getReference();
var imgRef:StorageReference = rootRef.child("images/img.png");

imgRef.remove(onDeleteSuccess, onDeleteFailed);

function onDeleteFailed(e:StorageEvents):void
{
	trace("onDeleteFailed with errorCode '" + e.errorCode + "' and msg: " + e.msg);
}

function onDeleteSuccess(e:StorageEvents):void
{
	trace("onDeleteSuccess");
}

Note: Deleting a file is a permenant action! If you care about restoring deleted files, make sure to back up your files, or enable object versioning on your Google Cloud Storage bucket.
