pnpm

pnpm is fast and disk-efficient. It uses a Content Addressable Store and hard links to avoid duplicating packages. v9 (2025) adds Catalogs.

When to Use

• Disk Space: Saves GBs by storing one copy of lodash globally.
• Speed: Installation is instant if packages are already in the store.
• Monorepos: Excellent workspace support with strict isolation.
