In the previous recipe, we discussed how we could upload files to theStorage bucket. In this part of the chapter, we're going to see how we can deliver and download our files directly from the Storage bucket.

How to do it...

Typically, we don't have a way to showcase all the files we have within our bucket. We do have files and folders in Firebase; however there's no API to showcase folders, but only to showcase files.
