node.js check available - Find the version of an installed npm package

10 Answers

Another quick way of finding out what packages are installed locally and without their dependencies is to use:

npm list --depth=0

Which gives you something like

├── bower@0.8.6
├── grunt@0.4.1
├── grunt-bower-requirejs@0.4.3
├── grunt-contrib-clean@0.4.1
├── grunt-contrib-coffee@0.7.0
├── grunt-contrib-copy@0.4.1
├── grunt-contrib-imagemin@0.1.4
├── grunt-contrib-jshint@0.1.1
├── grunt-contrib-livereload@0.1.2
├── grunt-contrib-requirejs@0.4.1
├── grunt-regarde@0.1.1
└── grunt-svgmin@0.1.0

Obviously, the same can be done globally with npm list -g --depth=0.

This method is clearer in case you have installed a lot of packages.

To find out which packages need to be updated, you can use npm outdated -g --depth=0.

How to find the version of an installed node.js/npm package?

This prints the version of npm itself:

npm -v <package-name>

This prints a cryptic error:

npm version <package-name>

This prints the package version on the registry (i.e. the latest version available):

npm view <package-name> version

How do I get the installed version?

npm info YOUR_PACKAGE version


npm info grunt version

From the root of the package do:

node -p "require('./package.json').version"

EDIT: (so you need to cd into the module's home directory if you are not already there. If you have installed the module with npm install, then it will be under node_modules/<module_name>)

EDIT 2: updated as per answer from @jeff-dickey

If you agree to install jq, you can use the JSON output of npm list.

npm -j ls <package-name> | jq -r .version

or, if you want to be verbose

npm --json list <package-name> | jq --raw-output '.version'

For instance:

$ npm -j ls ghost | jq -r .version

Also, the JSON format is slightly different for global packages, so you'll need to change the query.

For instance:

$ npm -j -g ls | jq -r .dependencies.ghost.version

You can use npm view [module] version, npm info [module] version, npm show [module] version or npm v [module] version to check the version on an installed npm module.

Let's suppose my grunt module version is the 0.4.5:

npm view grunt version => 0.4.5
npm info grunt version => 0.4.5
npm show grunt version => 0.4.5
npm v grunt version    => 0.4.5

To see all the installed packages locally or globally, use these commands:

  1. npm list for local packages or npm list -g for globally installed packages.
  2. npm list --depth=0
  3. npm list | sls <package name>
  4. node -v

Combining some of the above answers and produces a super simple and super quick lookup.
Run from project root. No need to cd into any folder, just 1 line:

node -p "require('SOMEPACKAGE/package.json').version"

You may try this: npm show {package} version shows the latest package version. And if your package is outdated, npm outdated will show it with version info.

I added this to my .bashrc

function npmv {
    case $# in # number of arguments passed
    0) v="$(npm -v)" ; #store output from npm -v in variable
        echo "NPM version is: $v"; #can't use single quotes 
                                   #${v} would also work
    1) s="$(npm list --depth=0 $1 | grep $1 | cut -d @ -f 2)";
       echo "$s";
    2) case "$2" in # second argument
        g) #global|#Syntax to compare bash string to literal
             s="$(npm list --depth=0 -g $1 | grep $1 | cut -d @ -f 2)";
        echo "$s";
        l) #latest
             npm view $1 version; #npm info $1 version does same thing
       *) echo 'Invalid arguments';
    *) echo 'Invalid arguments';
export -f npmv

Now all I have to do is type:

  • npmv for the version of npm eg: NPM version is: 4.2.0
  • npmv <package-name> for the local version eg: 0.8.08
  • npmv <package-name> g for global version eg: 0.8.09
  • npmv <package-name> l for latest version eg: 0.8.10

Note -d on cut command means delimit by, followed by @, then f means field the 2 means second field since there will be one either side of the @ symbol.

We can use npm view any-promise(your module name) -v
