pnpm uses hard links and symlinks to save one version of a module only ever once on a disk. When using npm or Yarn for example, if you have 100 projects using the same version of lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be saved in a single place on the disk and a hard link will put it into the
node_moduleswhere it should be installed.
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_modulesstructure 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.
Using a standalone script:
curl -L https://raw.githubusercontent.com/pnpm/self-installer/master/install.js | node
On Windows (PowerShell):
(Invoke-WebRequest 'https://raw.githubusercontent.com/pnpm/self-installer/master/install.js').Content | node
npx pnpm add -g pnpm
Once you first installed pnpm, you can upgrade it using pnpm:
pnpm add -g pnpm
Do you wanna use pnpm on CI servers? See: Continuous Integration.
Just use pnpm in place of npm. For instance, to install run:
For more advanced usage, read pnpm CLI on our website.
For using the programmatic API, use pnpm's engine: supi.
npm has a great package runner called npx. pnpm offers the same tool via the
pnpxcommand. The only difference is that
pnpxuses pnpm for installing packages.
The following command installs a temporary create-react-app and calls it, without polluting global installs or requiring more than one step!
pnpx create-react-app my-cool-new-app
pnpm is as fast as npm and Yarn. See all benchmarks here.
