## What it is
pnpm is a fast, disk space efficient package manager for Node.js and JavaScript projects that stores packages in a global content-addressable store and links them into projects. It supports monorepo workspaces, deterministic lockfiles, strict dependency access, and can also manage Node.js runtime versions.

## Use cases
- install javascript dependencies faster than npm
- save disk space when many projects share packages
- manage a monorepo with multiple packages and workspaces
- get deterministic installs with a lockfile
- prevent packages from accessing undeclared dependencies
- manage node.js versions alongside packages
- speed up CI builds with faster dependency installation
- mitigate npm supply chain attacks

## When to choose
- you work on JavaScript or TypeScript projects of any size
- you maintain a monorepo with many packages and want workspace support
- disk space or install speed is a concern across many projects
- you want strict, deterministic dependency resolution
- you need a battle-tested package manager used in production since 2016

## When to avoid
- you need a package manager for non-JavaScript ecosystems like Python, Rust, or Go
- your tooling or deployment pipeline assumes npm or Yarn-specific behavior
- you rely on packages that break under pnpm's symlinked node_modules layout
