npm-ls(3) -- List installed packages

SYNOPSIS, [silent,] callback)


This command will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure. It will also return that data using the callback.

This command does not take any arguments, but args must be defined. Beyond that, if any arguments are passed in, npm will politely warn that it does not take positional arguments, though you may set config flags like with any other command, such as global to list global packages.

It will print out extraneous, missing, and invalid packages.

If the silent parameter is set to true, nothing will be output to the screen, but the data will still be returned.



  • Default: false
  • Type: Boolean

Show extended information.


  • Default: false
  • Type: Boolean

Show parseable output instead of tree view.


  • Default: false
  • Type: Boolean

List packages in the global install prefix instead of in the current project.

Note, if parseable is set or long isn't set, then duplicates will be trimmed. This means that if a submodule a same dependency as a parent module, then the dependency will only be output once.
