Fast, disk space efficient npm installs

Package Exports

  • pnpm
  • pnpm/lib/bin/pnpm.js
  • 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.

Background

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

=> - a link (also known as a hard link)
-> - a symlink (or junction on Windows)

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 the programmatic API, see: API.

Benchmark

pnpm is usually 10 times faster than npm and 30% faster than yarn. See this benchmark which compares the three package managers on different types of applications.
