[中文](https://pnpm.io/zh/) | [Español](https://pnpm.io/es/) ![](https://i.imgur.com/qlW1eEG.png) Fast, disk space efficient package manager: * **Fast.** Up to 2x faster than the alternatives (see [benchmark](#benchmark)). * **Efficient.** Files inside `node_modules` are linked from a single content-addressable storage. * **[Great for monorepos](https://pnpm.io/workspaces).** * **Strict.** A package can access only dependencies that are specified in its `package.json`. * **Deterministic.** Has a lockfile called `pnpm-lock.yaml`. * **Works everywhere.** Supports Windows, Linux, and macOS. * **Battle-tested.** Used in production by teams of [all sizes](https://pnpm.io/users) since 2016. To quote the [Rush](https://rushjs.io/) team: > Microsoft uses pnpm in Rush repos with hundreds of projects and hundreds of PRs per day, and we’ve found it to be very fast and reliable.

When using npm or Yarn, if you have 100 projects using lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be stored in a content-addressable storage, so: 1. If you depend on different versions of lodash, only the files that differ are added to the store. If lodash has 100 files, and a new version has a change only in one of those files, `pnpm update` will only add 1 new file to the storage. 1. All the files are saved in a single place on the disk. When packages are installed, their files are linked from that single place consuming no additional disk space. Linking is performed using either hard-links or reflinks (copy-on-write). 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: [Flat node_modules is not the only way](https://pnpm.io/blog/2020/05/27/flat-node-modules-is-not-the-only-way). ## Installation On macOS, Linux, or Windows Subsystem for Linux: ``` curl -f https://get.pnpm.io/v6.js | node - add --global pnpm ``` On Windows (using PowerShell): ``` (Invoke-WebRequest 'https://get.pnpm.io/v6.js' -UseBasicParsing).Content | node - add --global pnpm ``` Using npm: ``` npx pnpm add -g pnpm ``` For other installation options [visit our website](https://pnpm.io/installation). ## Usage Just use pnpm in place of npm/Yarn. E.g., install dependencies via: ``` pnpm install ``` Also, pnpx instead of npx: ``` pnpx create-react-app my-cool-new-app ``` For more advanced usage, read [pnpm CLI](https://pnpm.io/pnpm-cli) on our website, or run `pnpm help`. ## Benchmark pnpm is up to 2x faster than npm and Yarn classic.
