Background

pnpm maintains a flat storage of all your dependencies in node_modules/.store. They are then symlinked wherever they're needed. This nets you the benefits of less disk space usage, while keeping your node_modules clean. See store layout for an explanation.

.
└─ node_modules/
   ├─ .store/
   │  ├─ chalk@1.1.1/_/
   │  │  └─ node_modules/
   │  │     ├─ ansi-styles      -> ../../../ansi-styles@2.1.0/_
   │  │     └─ has-ansi         -> ../../../has-ansi@2.0.0/_
   │  ├─ ansi-styles@2.1.0/_/
   │  └─ has-ansi@2.0.0/_/
   └─ chalk                     -> .store/chalk@1.1.1/_

Install

Install it via npm.

npm install -g pnpm

Usage

Use pnpm in place of npm. It overrides pnpm i, pnpm install and some other command, the rest will passthru to npm.

pnpm install lodash

Custom registries

pnpm uses whatever npm's configured to use as its registry. See: custom registries.

Preview release

pnpm will stay in <1.0.0 until it's achieved feature parity with npm install. See roadmap for details.
