Performant npm installations

pnpm is a fast implementation of npm install. It is loosely based off ied.

npm version Status Windows build status


Install it via npm.

npm install -g pnpm

Use pnpm in place of npm. It overrides pnpm i and pnpm install—all other commands 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.

pnpm maintains a flat storage of all your dependencies in node_modules/.store. They are then symlinked wherever they're needed. See store layout for an explanation.
