Fast, efficient package manager

Features

• Fast. Up to 2x faster than the alternatives (see benchmark).
• Efficient. Files inside node_modules are linked from a single content-addressable storage.
• Great for monorepos.
• Strict. A package can access only dependencies that are specified in its package.json.
• Deterministic. Has a lockfile called pnpm-lock.yaml.
• Works as a Node.js version manager. See pnpm env use.
• Works everywhere. Supports Windows, Linux, and macOS.
• Battle-tested. Used in production by teams of all sizes since 2016.
• See the full feature comparison with npm and Yarn.

      • Packages are stored in a global store (Virtual Store) / linked to the project's node_modules via symlinks
      • Duplicate packages are not installed, saving storage space and network
    • Packages are linked to each other automatically, making monorepo setup simpler
    • Features used in Yarn Berry, such as patch-package and dedupe, can be used almost as-is
