pnpm

Project Overview

pnpm is a fast, disk space-efficient package manager. It uses a content-addressable filesystem to store all files, linking them into node_modules via hard links or reflinks, which saves disk space and speeds up installations. It has built-in support for monorepos.

Key Features

• Fast: Up to 2x faster than npm and Yarn
• Disk space efficient: Uses hard links or reflinks to share files
• Strict: A package can only access dependencies declared in its package.json
• Monorepo support: Built-in workspace support
• Deterministic: Uses a pnpm-lock.yaml lockfile
• Node.js version manager: Can be used as a Node.js version manager
• Works everywhere: Supports Windows, Linux, and macOS

Target Audience

• Node.js developers seeking faster installations and less disk usage
• Teams managing large monorepo projects
• Users who want stricter dependency management

Quick Start

• Install: Follow the Installation guide
• Usage: pnpm install to install dependencies, pnpm add <pkg> to add a package

Core Advantages

• Exceptional speed and disk space efficiency
• Native monorepo support
• Strict dependency management to avoid phantom dependencies
