pnpm is a fast, disk space efficient package manager for JavaScript that works with the npm and Yarn registries. It uses hard links and symlinks to save disk space and improve installation speed. It also has a strict node_modules structure that helps to avoid issues with phantom dependencies.
Installing packages
Installs the lodash package into your project. This is similar to npm install or yarn add.
pnpm install lodashCreating a new project
Initializes a new package.json file for your project, similar to npm init or yarn init.
pnpm initAdding a package to dependencies
Adds the react package to your project's dependencies, similar to npm install react --save or yarn add react.
pnpm add reactAdding a package to devDependencies
Adds the typescript package to your project's devDependencies, similar to npm install typescript --save-dev or yarn add typescript --dev.
pnpm add --save-dev typescriptUpdating packages
Updates all the packages in your project to their latest versions based on the specified ranges in package.json, similar to npm update or yarn upgrade.
pnpm updateRunning scripts
Runs the script named 'build' specified in your package.json, similar to npm run build or yarn run build.
pnpm run buildnpm is the default package manager for Node.js and is the most widely used. It has a large ecosystem and is well-supported, but it can be slower and use more disk space compared to pnpm.
Yarn is a package manager that was created by Facebook to address some of npm's shortcomings. It introduced lockfiles and deterministic installations. Yarn is faster than npm but can still use more disk space compared to pnpm.
Performant npm installations
pnpm is a fast implementation of npm install. It is loosely based off ied.
⚠ Name change
The npm package was changed from
pnpm.js(0.15 and below) topnpm. The old package will no longer be updated. For old users, uninstall the old version and install the new one:npm uninstall -g pnpm.js npm install -g pnpm
Install it via npm.
npm install -g pnpm
Use pnpm in place of npm. It overrides pnpm i and pnpm install—all other commands will passthru to npm.
pnpm install lodash
pnpm uses whatever npm's configured to use as its registry. See: custom registries.
pnpm will stay in <1.0.0 until it's achieved feature parity with npm install. See roadmap for details.

pnpm maintains a flat storage of all your dependencies in node_modules/.store. They are then symlinked whereever they're needed.
See store layout for an explanation.
