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.

Background pnpm uses a content-addressable filesystem to store all files from all module directories on a disk. 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! 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). 💖 Like this project?

E.g., install dependencies via: ``` pnpm install ``` 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.
