Google AppEngine createUploadUrl in node

In PHP, it is really easy to create an upload url with an endpoint.

$options = ['gs_bucket_name' => $my_bucket];
$upload_url = CloudStorageTools::createUploadUrl('/upload/handler', $options);

I was wondering if there is a way to do this in Node because I can't seem to figure out how
