Vitaly Zdanevich zdanevich.vitaly@ya.ru * Fast. Up to 2x faster than the alternatives. * Efficient. Files inside node_modules are linked from a single content-addressable storage * Great for monorepos. * 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. * Battle-tested. Used in production by teams of all sizes since 2016. To quote the Rush 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". 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: * 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. * 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! pnpm/pnpm https://github.com/pnpm/pnpm/issues
