Node Modules Black Hole
ELI5 — The Vibe Check
The node_modules black hole is the abyss that forms when you run npm install. What starts as 5 dependencies becomes 500 nested packages totaling 400MB. It's the heaviest object in the known universe. Deleting it takes longer than downloading it. Every JavaScript developer has a hard drive graveyard of abandoned projects where node_modules is the tombstone.
Real Talk
The node_modules black hole refers to the notorious size and depth of Node.js dependency trees. A project with a handful of direct dependencies may resolve to hundreds or thousands of transitive dependencies, consuming significant disk space. This is a consequence of npm's flat dependency resolution, JavaScript's micro-package culture, and the tendency to depend on packages for trivial functionality (e.g., the left-pad incident).
When You'll Hear This
