Summary
Reverse dependencies is the tool that answers the question you cannot answer from the gem's own page.
"Who relies on this" decides whether a gem is safe to depend on and how bad a breaking change would be, and the registry page shows you the opposite direction. Having it as a first-class query — alongside an owner's full list, which is how you judge whether a maintainer is a going concern — makes this a due-diligence tool rather than a lookup. Small, read-only, cheap to keep connected.
What it is
A reader for the RubyGems registry, exposing the queries you actually make when evaluating or tracing a gem.
What you get
- get_rubygem_info — one gem's metadata
- search_rubygems — find gems matching a query
- get_gem_versions — every published version
- get_gem_reverse_dependencies — what depends on this gem
- get_owner_gems — everything a given owner publishes
Requirements
Node.
