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.

Fast, disk space efficient package manager:
node_modules are linked from a single content-addressable storage.package.json.pnpm-lock.yaml.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:
pnpm update will only add 1 new file to the storage.As a result, you save gigabytes of space on your disk and you have a lot faster installations!
