How to List Npm User-Installed Packages?

You can get a list of all globally installed modules using:

ls `npm root -g`

As of 13 December 2015

Whilst I found the accepted answer 100% correct, and useful, wished to expand upon it a little based on my own experiences, and hopefully for the benefit of others too. (Here I am using the terms package and module interchangeably)

In answer to the question, yes the accepted answer would be:

npm list -g --depth=0

You might wish to check for a particular module installed globally, on *nix systems / when grep available. This is particularly useful when checking what version of a module you are using (globally installed, just remove the -g flag if checking a local module):

npm list -g --depth=0 | grep <module_name>

If you'd like to see all available (remote) versions for a particular module, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

For latest remote version:

npm view <module_name> version  

Note, version is singular.

To find out which packages need to be updated, you can use

npm outdated -g --depth=0

To update global packages, you can use

npm update -g <package>

To update all global packages, you can use:

npm update -g

(However, for npm versions less than 2.6.1, please also see this link as there is a special script that is recommended for globally updating all packages).

The above commands should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

List NPM packages with some friendly gui!

This is what I personally prefer and it may be for others too, it may also help during presentations or meetings.

With npm-gui you can list local and global packages with a better visualization.

You can find the package at

Run the following

//Once
npm install -g npm-gui

cd c:\your-prject-folder
npm-gui localhost:9000

Then open your browser at http:\\localhost:9000

For project dependencies use:

npm list --depth=0

For global dependencies use:

npm list -g --depth=0

npm ls

npm list is just an alias for npm ls

For the extended info use

npm la    
npm ll

You can always set --depth=0 at the end to get the first level deep.

npm ls --depth=0

You can check development and production packages.

npm ls --only=dev
npm ls --only=prod

To show the info in json format

npm ls --json=true

The default is false

npm ls --json=false

You can insist on long format to show extended information.

npm ls --long=true

You can show parseable output instead of tree view.

npm ls --parseable=true

You can list packages in the global install prefix instead of in the current project.

npm ls --global=true
npm ls -g // shorthand

Full documentation you can find here.

Node has a concept of Local modules & Global modules

Local modules are located within current project directory.

Global Modules are generally located at user's home directory, though we can change the path where global modules resides.

1. Lists local modules within current dir: npm list
2. Lists global modules : npm list --global OR npm list --g // It will list all the top level modules with its dependencies
3. List only top level(Installed modules) global modules : npm list -g --depth=0

One way might be to find the root directory of modules using:

npm root
/Users/me/repos/my_project/node_modules

And then list that directory...

ls /Users/me/repos/my_project/node_modules
grunt                   grunt-contrib-jshint

The user-installed packages in this case are grunt and grunt-contrib-jshint

I use npm -g outdated --depth=0 to list outdated versions
in the global space.

To see list of all packages that are installed.

$ npm ls --parseable | awk '{gsub(/\/.*\//,"",$1); print}'| sort -u

show parseable of npm packages list

You can try NPM Desktop manager

With just one click, you can install/uninstall packages in dev or global status.

Node_modules contains user-installed packages so change the directory to node_modules and list the items. Core Modules are defined in node's source in the lib/ folder.

Example:

     example@example:~/:~/node_modules$ ls
     express  maxmind-native  node-whois  socket.io  ua-parser-js
     geoip    mongoskin       pdfkit      tail       zeromq
     maxmind  nodemailer      request     ua-parser  zmq

As the end of 2021, there are few obvious way to do it, despite all the other answer are still working I think an update is needed besides a more defined and complete list of commands possible, and while am I at it, I added some other common commands for whom needs it (install, uninstall etc..)

# bare command
npm list
# ls is an alias of list
npm ls 
# don't shows dependencies
npm list --depth=0
# Global modules
npm list -g --depth=0
# More info
npm la    
npm ll
# show particual env packages
npm ls --only=dev
npm ls --only=prod
# parseable view (tree view)
npm ls --parseable=true

The Node.js Documentation is actually pretty well explained regarding the matter, this is a collective list of the main commands.

Before start NOTE:

All Commands will run the list of installed modules Locally. In order to run global level just add a -g flag at the end of the statement.
