Installation and use of pnpm

The original intention of the project

When using npm or Yarn when , If you have 100 A project uses a dependency （dependency）, There will be 100 A copy of this dependency is saved on the hard disk . But in the use of pnpm when , Dependencies are stored in content addressable storage , therefore ：

1. If you use different versions of a dependency , Only different versions of files will be added to the warehouse . for example , If a package has 100 File , And its new version only changes 1 File . that pnpm update Only additional... Will be added to the storage center 1 A new document , Instead of copying the contents of the new version package just because of the change of one file .
2. All files will be stored in a location on the hard disk . When the package is installed , The files in the package will be hard linked to this location , Without taking up additional disk space . This allows you to share the same version of dependencies across projects .

therefore , You save a lot of space on disk , This is proportional to the number of projects and dependencies , And the installation speed is much faster ！
