You can also use cloud.google.com/storage/transfer to do one-time or recurring transfers from one bucket to another. – Whipsaw

Answer 1

You can try something like this:

'use strict'

var async = require('async')
var storage = require('@google-cloud/storage')()
var bucket = storage.bucket('stephen-has-a-new-bucket')

bucket.renameFolder = function(source, dest, callback) {
  bucket.getFiles({ prefix: source }, function(err, files) {
    if (err) return callback(err)

    async.eachLimit(files, 5, function(file, next) {
      file.move(file.name.replace(source, dest), next)
    }, callback)
  })
}

bucket.renameFolder('photos/cats', 'photos/dogs', console.log)

Thanks, but once the files are moved, they are no long public. Is there a way to maintain the public attribute? – Flagellate

Answer 2

There are no folders. There is simply a collection of objects that all happen to have the same key prefix, for example photos/animals/cat.png and photos/animals/dog.png both have a common prefix photos/animals/ and that's what makes them appear to be in the same folder.

You will need to copy (or move) each of the objects to its new key, for example move photos/animals/cat.png to photos/pets/cat.png and move photos/animals/dog.png to photos/pets/dog.png.

That said, Google Cloud provides a way to do this from the command line using gsutil mv.
