A fast implementation of npm install

Package Exports

  • pnpm
  • pnpm/lib/bin/pnpm.js
  • pnpm/lib/logger
  • pnpm/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pnpm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Table of Contents

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.

Install

Install it via npm.

npm install -g pnpm

Do you wanna use pnpm on CI servers? See: Continuous Integration.

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

For using globally installed packages, see: global install.

For using the programmatic API, see: API.
