To see the latest version of all the npm packages installed, including their dependencies:

npm list

Example:

❯ npm list
/Users/flavio/dev/node/cowsay
└─┬ cowsay@1.3.1
  ├── get-stdin@5.0.1
  ├─┬ optimist@0.6.1
  │ ├── minimist@0.0.10
  │ └── wordwrap@0.0.3
  ├─┬ string-width@2.1.1
  │ ├── is-fullwidth-code-point@2.0.0
  │ └─┬ strip-ansi@4.0.0
  │   └── ansi-regex@3.0.0
  └── strip-eof@1.0.0

You can also just open the package-lock.json file, but this involves some visual scanning.

npm list -g is the same, but for globally installed packages.

To get only your top-level packages (basically, the ones you told npm to install and you listed in the package.json), run npm list --depth=0:

❯ npm list --depth=0
/Users/flavio/dev/node/cowsay
└── cowsay@1.3.1

You can get the version of a specific package by specifying the name:

❯ npm list cowsay
/Users/flavio/dev/node/cowsay
└── cowsay@1.3.1

This also works for dependencies of packages you installed:

❯ npm list minimist
/Users/flavio/dev/node/cowsay
└─┬ cowsay@1.3.1
  └─┬ optimist@0.6.1
    └── minimist@0.0.10

To see the latest version available on the npm registry, run npm view <package_name> version:

❯ npm view cowsay version

1.3.1
