pnpm Has a Free Package Manager That Saves 50% Disk Space

pnpm uses hard links and a content-addressable store. 100 projects sharing lodash? One copy on disk. Install times are 2x faster than npm.

Same interface, better performance. Disk Space Savings Real numbers from a developer with 50 projects:
