Overview
PNPM (Performant NPM) is known for being significantly faster and more disk-efficient than both NPM and Yarn. It achieves this by using hard links and symlinks to share a single copy of a package across multiple projects.
Key Benefits
- Disk Space Efficiency: Only one copy of a package is stored on your machine.
- Speed: Extremely fast installation times.
- Strictness: Prevents 'phantom dependencies' by ensuring code can only access packages explicitly listed in
package.json. - Monorepo Support: Excellent built-in support for multi-package projects.
Popularity
PNPM has seen a massive surge in popularity among developers who value performance and clean dependency management.
