Fast, disk space efficient package manager:
- Fast. Up to 2x faster than the alternatives (see benchmark).
- 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. See pnpm env use.
- Works everywhere. Supports Windows, Linux, and macOS.
- Battle-tested. Used in production by teams of all sizes since 2016.
- See the full feature comparison with npm and Yarn.
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.

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:- If you depend on different versions of lodash, only the files that differ are added to the store.
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
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 nodemodules is not the only way.💖 Like this project? Let people know with a tweet
