Terminal: npm

Working in the terminal with web development, you’ll likely be running into Node and the Node Package Manager (npm) sooner or later. It’s a standardized way to install and use JavaScript-based software — here’s a summary of some useful commands.

Packages can be installed globally or per project.

Global packages

• List all globally installed packages
  npm list -g --depth=0

• You can check for a particular module installed globally. This is particularly useful when checking what version of a module you are using globally (remove the -g flag if checking a local module):
  npm list -g --depth=0 | grep <module_name>

Packages

• If you’d like to see all available (remote) versions for a particular module, then do:
  npm view <module_name> versions.
  Note that versions is in the plural. This will give you a complete listing of versions to choose from.

• For the latest remote version:
  npm view <module_name> version  
  Note that the 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  npm outdated -g --depth=0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 install -g <package>

• To update all global packages, you can use:
  npm update -g

Another way would be to use npm-check-updates (or ncu for short).
