[Verse 1] When you pull a package down, it brings friends along Direct dependencies that you chose to make your code strong But look a little deeper, there's a hidden family tree Transitive dependencies, layers you might never see [Chorus] Map the graph, trace the path Direct flows to transitive math Optional deps when you need them most Dev deps build but don't ship with your host Know your tree, dependency From the root to every leaf [Verse 2] Maven Central, npm registry, PyPI's Python store Gradle builds and Cargo ships from Rust's abundant shore Pub delivers Dart and Flutter, each ecosystem's way But the same name, different worlds, might not work the same way [Chorus] Map the graph, trace the path Direct flows to transitive math Optional deps when you need them most Dev deps build but don't ship with your host Know your tree, dependency From the root to every leaf [Bridge] Source repo holds the code But the artifact you load Came from a build machine That's not what the source has seen Same commit, different time Different build, different rhyme Hash may match but binary's new Reproducibility's not true [Verse 3] Provenance tells the story of how your package came to be From developer's laptop to the registry you see Build environment matters, compiler versions too The same source code can create binaries brand new [Chorus] Map the graph, trace the path Direct flows to transitive math Optional deps when you need them most Dev deps build but don't ship with your host Know your tree, dependency From the root to every leaf [Outro] Trust but verify the chain From source to build to your domain Dependencies run deep and wide Know your supply chain, be your guide
