npm FAQ
  • How do I get help? 
    npm help [command]
  • How do I find my installed version? 
    npm -v
  • How do I list all installed packages and their dependencies?
    List all local packages: 
    npm ls

    List all global packages: 
    npm ls -g
  • How do I list just the installed packages (without dependencies)?
    List local packages: 
    npm ls --depth=0

    List global packages: 
    npm ls --depth=0 -g
  • How do I list all dependencies of a single module?
    List dependencies of a single package via the remote npm repo: 
    npm view <module>[@version] dependencies

    Or your local install: 
    # first, cd to any package
cd my-projects/example-1/node_modules/<module>

# then list its dependencies
npm ls
  • How do I install a module as a global executable (e.g., command-line utility)?
    Install it globally by using the -g option. Example: 
    # install the grunt command-line utility globally (so it can be added to the system path and enable it to be used in any directory).
sudo npm install -g grunt-cli
  • How do I install a module for use by an app (with require)?
    The module must be installed separately for each app. Example: 
    # install grunt for use by lab-kit-js (optionally add --save-dev to auto-update the package.json file).
cd /Users/George/Projects/html5/lab-kit-js
sudo npm install grunt --save-dev

# install grunt for use by css-lab (optionally add --save-dev to auto-update the package.json file).
cd /Users/George/Projects/html5/css-lab
sudo npm install grunt --save-dev
    Note: npm is not Maven. Released packages are not stable. Until just recently, you could force publish a released packaged module (i.e., a v1.2 module behaved like a maven v1.2-SNAPSHOT).
  • How do I uninstall a module? 
    npm uninstall <module> [-g] [--save|--save-dev|--save-optional]
  • How do I clean the npm cache? 
    sudo npm cache clean -f
  • How do I upgrade npm to the latest version? 
    npm update npm -g
