Different tools specific to their job, they wouldn't be good to combine together. apt-get only exists for linux, requires root and is designed for that, npm doesn't. apt-get installs the latest version, npm expects more specific verisons since it's for code. npm is built for node's ecosystem and apt-get is better for system packages.
