 Each tool has an abstraction to just build the node_modules (dependencies) directory.
 You can always use the `stdenv.mkDerivation` with the node_modules to build the package (symlink the node_modules directory and then use the package build command).
 The node_modules abstraction can be also used to build some web framework frontends.
