pnpm

[简体中文](https://pnpm.io/zh/) | [日本語](https://pnpm.io/ja/) | [한국어](https://pnpm.io/ko/) | [Italiano](https://pnpm.io/it/) | [Português Brasileiro](https://pnpm.io/pt/) 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 as a Node.js version manager.** See [pnpm runtime](https://pnpm.io/11.x/cli/runtime). * **Works everywhere.** Supports Windows, Linux, and macOS. * **Battle-tested.** Used in production by teams of [all sizes](https://pnpm.io/workspaces#usage-examples) since 2016. * **Experimental Rust port.** Includes [pacquet](./pnpm), an experimental port of the CLI written in Rust. * [See the full feature comparison with npm and Yarn](https://pnpm.io/feature-comparison). 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. ## Platinum Sponsors ## Gold Sponsors ## Silver Sponsors

When using npm, 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!
