pnpm Mechanics

pnpm is the preferred Node package manager in Dev-Centr shops. It stores packages in a content-addressable store and links them into project node_modules/ with a stricter layout than classic npm hoisting, which cuts disk waste and makes phantom dependencies harder to rely on by accident.

Why we prefer it

  • Disk: One copy of a given package version on disk, reused across projects.

  • Correctness: Stricter resolution than flattened node_modules trees that accidentally “see” undeclared packages.

  • Monorepos: First-class workspace workflows for multi-package repos.

Among alternatives

For Bun, Yarn, npm, and the aspirational role of Orogene (closed-source today; once-and-future open inspiration), see npm package managers and alternatives. That page is the comparison; this page stays focused on pnpm’s mechanics and shop default.
