What is a difference between installing npm module locally and globally?

Experience Level: Senior
Tags: npm


When you install a module locally: 

  • It will be installed into your local folder.
  • The module is then not visible outside of this folder.
  • You can have multiple installations of the same module in different folders.
  • You can install different versions of the same module side by side.

When you install a module globally:

  • It can be used from all the other directories.
  • Only one version of the module can be installed.
  • You should install a module globally when you want to use it in multiple different projects without having a maintenance overhead.
