pnpm is a fast, disk-efficient package manager for Node.js that uses a content-addressable storage system. Instead of copying packages into each project's node_modules, pnpm creates hard links from a single global store, dramatically reducing disk usage when multiple projects share the same dependencies.
It provides a strict node_modules structure that prevents accessing undeclared dependencies, improving project reliability. The CLI is largely compatible with npm, supporting install, add, remove, update, and run commands with similar syntax. Workspace support via -r (recursive) enables managing monorepo projects.

Node.js required. Uses hard links for efficiency.

pnpm was created as a fast alternative to npm with better disk usage.
