NAME
npm-ls - List installed packages
SYNOPSIS
npm.commands.ls(args, [silent,] callback)
DESCRIPTION
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.
Callback is provided an error if one occurred, the full data about which packages are installed and which
dependencies they will receive, and a "lite" data object which just shows which versions are installed
where. Note that the full data object is a circular structure, so care must be taken if it is serialized
to JSON.
CONFIGURATION
long
• Default: false
• Type: Boolean
Show extended information.
parseable
• Default: false
• Type: Boolean
Show parseable output instead of tree view.
global
• 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.
