I understand you want to perform these queries on NPM packages, not Guix
packages, but if you could hook your NPM package representation in (guix
graph)¹, you could do the same as this:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(guix graph)
scheme@(guile-user)> ,use(guix scripts graph)
scheme@(guile-user)> ,use(gnu packages)
scheme@(guile-user)> ,use(guix monad-repl)
scheme@(guile-user)> ,enter-store-monad
store-monad@(guile-user) [1]> (node-back-edges %bag-node-type (fold-packages cons '()))
$4 = #<procedure 59ac880 at guix/graph.scm:87:17 (node)>
store-monad@(guile-user) [1]> ,q
scheme@(guile-user)> ,use(srfi srfi-1)
scheme@(guile-user)> (filter (lambda (p)
                               (> (node-reachable-count (list p) $4)
                                  600))
                             (fold-packages cons '()))
