Much more so than internet posts about it, there are countless modules for NodeJS as well. Need to upload and store and return images in Monogo using streaming? Done. Need to keep servers running despite errors? Done. Amazon S3? Done. Need an alternate cloud provider? Done. Need login using OAUTH/OpenID/whatever? Done. On and on. Most times you need some general purpose web functionality, there's already a couple Node modules in that area, if not an entire framework or sample app and tutorial targeted at that area.
