pnpm is a fast, disk space-efficient package manager for JavaScript and Node.js projects. It uses a unique symlink-based approach to manage dependencies, storing them in a global content-addressable store and linking them into projects as needed. This results in faster installs and significant disk space savings, especially in monorepos or environments with many projects.
A key advantage of pnpm is its strict enforcement of dependency boundaries: packages can only access dependencies they explicitly declare. This prevents "ghost dependencies"—a common issue with npm and Yarn classic—leading to more reliable builds and easier maintenance.
pnpm is highly compatible with the npm ecosystem, supports workspaces, and integrates smoothly with modern development workflows. Its performance, reliability, and focus on correctness make it our recommended choice for managing Node.js project dependencies.
