    Background

    pnpm uses hard links and symlinks to save one version of a module only ever once on a disk. When using npm or Yarn for example, if you have 100 projects using the same version of lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be saved in a single place on the disk and a hard link will put it into the node_modules where it should be installed.

    As a result, you save gigabytes of space on your disk and you have a lot faster installations! If you'd like more details about the unique node_modules structure that pnpm creates and why it works fine with the Node.js ecosystem, read this small article: Why should we use pnpm?

    Install

    Using a standalone script:

    curl -L https://unpkg.com/@pnpm/self-installer | node
    

    Via npm:

    npm install -g pnpm
    

    Once you first installed pnpm, you can upgrade it using pnpm:

    pnpm install -g pnpm

    Usage

    pnpm CLI

    Just use pnpm in place of npm. For instance, to install run:

    pnpm install lodash
    

    For more advanced usage, read pnpm CLI on our website.

    For using the programmatic API, use pnpm's engine: supi.

    pnpx CLI

    npm has a great package runner called npx. pnpm offers the same tool via the pnpx command. The only difference is that pnpx uses pnpm for installing packages.

    The following command installs a temporary create-react-app and calls it, without polluting global installs or requiring more than one step!

    pnpx create-react-app my-cool-new-app
    

    Benchmark

    pnpm is faster than npm and Yarn. See this benchmark which compares the three package managers on different types of applications.
