Report #61468

[tooling] Bloated node\_modules with duplicate transitive dependencies and inability to determine which parent package requires a specific vulnerable or duplicated subdependency

Run npm explain to display the full dependency tree path explaining why a package is installed, revealing which top-level dependencies pull in the transitive bloat

Journey Context:
Developers often run npm ls which shows flat lists or fails with peer dependency errors, but cannot answer 'why is lodash@3 here when I have lodash@4?'. npm explain traces the precise path from the root package down through transitive dependencies to the target, showing version conflicts and deduplication opportunities. Unlike manual package.json inspection, it resolves the actual installed tree, essential for pruning bloat, auditing security vulnerabilities in transitive deps, or identifying which top-level dependency upgrade would eliminate an old transitive version.
