What is pnpm?

It 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_modules where it should be installed.
pnpm is a tool in the Package Managers category of a tech stack.
pnpm is an open source tool with 21.7K GitHub stars and 643 GitHub forks. Here’s a link to pnpm's open source repository on GitHub
