Move/rename folder in Google Cloud Storage using nodejs gcloud api

I am trying to rename or move a folder in google cloud storage using the gcloud api.

A similar question explains how to delete a folder: Delete folder in Google Cloud Storage using nodejs gcloud api

But how can one rename a folder? or move to another path?

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)
