Fast, disk space efficient npm installs
pnpm is a fast implementation of npm install. It is loosely based off ied.

Follow the pnpm Twitter account for updates.
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 it via npm.
npm install -g pnpm
Do you wanna use pnpm on CI servers? See: Continuous Integration.
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.
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.

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