Synopsis

npm ls <package-spec>

alias: list

Description

This command will print to stdout all the versions of packages that are installed, as well as their dependencies when --all is specified, in a tree structure.

Note: to get a "bottoms up" view of why a given package is included in the tree at all, use npm explain.

Positional arguments are name@version-range identifiers, which will limit the results to only the paths to the packages named. Note that nested packages will also show the paths to the specified packages. For example, running npm ls promzard in npm's source tree will show:

npm@11.7.0 /path/to/npm
└─┬ init-package-json@0.0.4
  └── promzard@0.1.5

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

If a project specifies git urls for dependencies these are shown in parentheses after the name@version to make it easier for users to recognize potential forks of a project.

The tree shown is the logical dependency tree, based on package dependencies, not the physical layout of your node_modules folder.

When run as ll or la, it shows extended information by default.

Configuration

`all`

Default: false
Type: Boolean

When running npm outdated and npm ls, setting --all will show all outdated or installed packages, rather than only those directly depended upon by the current project.

`json`

Default: false
Type: Boolean

Whether or not to output JSON data, rather than the normal output.

In npm pkg set it enables parsing set values with JSON.parse() before saving them to your package.json.

Not supported by all npm commands.

`long`

Default: false
Type: Boolean

Show extended information in ls, search, and help-search.

`parseable`

Default: false
Type: Boolean

Output parseable results from commands that write to standard output. For npm search, this will be tab-separated table format.

`global`

Default: false
Type: Boolean

Operates in "global" mode, so that packages are installed into the prefix folder instead of the current working directory. See folders for more on the differences in behavior.

packages are installed into the {prefix}/lib/node_modules folder, instead of the current working directory.
bin files are linked to {prefix}/bin
man pages are linked to {prefix}/share/man

`depth`

Default: Infinity if --all is set; otherwise, 0
Type: null or Number

The depth to go when recursing packages for npm ls.

If not set, npm ls will show only the immediate dependencies of the root project. If --all is set, then npm will show all dependencies by default.

`omit`

Default: 'dev' if the NODE_ENV environment variable is set to 'production'; otherwise, empty.
Type: "dev", "optional", or "peer" (can be set multiple times)

Dependency types to omit from the installation tree on disk.

Note that these dependencies are still resolved and added to the package-lock.json or npm-shrinkwrap.json file. They are just not physically installed on disk.

If a package type appears in both the --include and --omit lists, then it will be included.

If the resulting omit list includes 'dev', then the NODE_ENV environment variable will be set to 'production' for all lifecycle scripts.

`include`

Default:
Type: "prod", "dev", "optional", or "peer" (can be set multiple times)

Option that allows for defining which types of dependencies to install.

This is the inverse of --omit=<type>.

Dependency types specified in --include will not be omitted, regardless of the order in which omit/include are specified on the command-line.

`link`

Default: false
Type: Boolean

Used with npm ls, limiting output to only those packages that are linked.

`package-lock-only`

Default: false
Type: Boolean

If set to true, the current operation will only use the package-lock.json, ignoring node_modules.

For update this means only the package-lock.json will be updated, instead of checking node_modules and downloading dependencies.

For list this means the output will be based on the tree described by the package-lock.json, rather than the contents of node_modules.

`unicode`

Default: false on windows, true on mac/unix systems with a unicode locale, as defined by the LC_ALL, LC_CTYPE, or LANG environment variables.
Type: Boolean

When set to true, npm uses unicode characters in the tree output. When false, it uses ascii characters instead of unicode glyphs.

`workspace`

Default:
Type: String (can be set multiple times)

Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option.

Valid values for the workspace config are either:

Workspace names
Path to a workspace directory
Path to a parent workspace directory (will result in selecting all workspaces within that folder)

When set for the npm init command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project.

This value is not exported to the environment for child processes.

`workspaces`

Default: null
Type: null or Boolean

Set to true to run the command in the context of all configured workspaces.

Explicitly setting this to false will cause commands like install to ignore workspaces altogether. When not set explicitly:

Commands that operate on the node_modules tree (install, update, etc.) will link workspaces into the node_modules folder. - Commands that do other things (test, exec, publish, etc.) will operate on the root project, unless one or more workspaces are specified in the workspace config.

This value is not exported to the environment for child processes.

`include-workspace-root`

Default: false
Type: Boolean

Include the workspace root when workspaces are enabled for a command.

When false, specifying individual workspaces via the workspace config, or all workspaces via the workspaces flag, will cause npm to operate only on the specified workspaces, and not on the root project.

This value is not exported to the environment for child processes.

`install-links`

Default: false
Type: Boolean

When set file: protocol dependencies will be packed and installed as regular dependencies instead of creating a symlink. This option has no effect on workspaces.
