What it is
A package manager that hard-links a single global content-addressed store instead of copying packages into every
node_modules. Now at v11. Its strict, non-flat layout means a package you never declared cannot be imported by accident.Why it earns a slot
Saves gigabytes across projects and catches phantom dependencies that work locally but break in production. It is the default for most monorepos and the safest npm replacement if Bun feels too new.
Know before you commit
The strict layout breaks packages with undeclared peer deps — you may need
node-linker=hoisted in .npmrc for stubborn tools.Getting started
npm install -g pnpm
