npm: Find the installed version of an npm package

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

npm list

Example:

❯ npm list
/Users/flavio/dev/node/cowsay
└─┬ [email protected]
  ├── [email protected]
  ├─┬ [email protected]
  │ ├── [email protected]
  │ └── [email protected]
  ├─┬ [email protected]
  │ ├── [email protected]
  │ └─┬ [email protected]
  │   └── [email protected]
  └── [email protected]

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
└── [email protected]

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

❯ npm list cowsay
/Users/flavio/dev/node/cowsay
└── [email protected]

This also works for dependencies of packages you installed:

❯ npm list minimist
/Users/flavio/dev/node/cowsay
└─┬ [email protected]
  └─┬ [email protected]
    └── [email protected]

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

❯ npm view cowsay version
