How to download entire folder from Firebase Storage?

Question

I want to download an entire folder from Firebase storage. I can download single files using DownloadURL as follows, but it does not work for folders.

var storageRef = firebase.storage().ref();

// Create a reference to the file we want to download
var starsRef = storageRef.child(path);

// Get the download URL
starsRef.getDownloadURL().then(function(url) {
  // Insert url into an <img> tag to "download"
  ImageUrl = url;

  console.log(ImageUrl);
}).catch(function(error) {
  switch (error.code) {
    case 'storage/object_not_found':
      // File doesn't exist
      break;

    case 'storage/unauthorized':
      // User doesn't have permission to access the object
      break;

    case 'storage/canceled':
      // User canceled the upload
      break;

    case 'storage/unknown':
      // Unknown error occurred, inspect the server response
      break;
  }
});
