pnpm

pnpm is the high-performance JavaScript package manager trusted by companies like Microsoft, Bytedance, and Vue.js to dramatically reduce disk space usage and installation times through intelligent symlink-based storage. As the most efficient package manager available, it can reduce node_modules disk usage by up to 95% while installing packages up to 2x faster than npm, making it essential for large-scale JavaScript development.

What makes pnpm exceptional is its revolutionary content-addressable storage system that maintains a single global store of packages, linking them into projects as needed rather than duplicating files. This approach not only saves massive amounts of disk space but also eliminates phantom dependency issues that plague other package managers while maintaining full npm compatibility.

Development teams choose pnpm because it solves the fundamental inefficiencies of traditional package management without requiring workflow changes. From enterprise monorepos to individual projects, it provides the optimized foundation that modern JavaScript development demands.
