Find the version of an installed npm package

Question

How can I find the version of an installed Node.js or 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?

Answer 1

Use npm list for local packages or npm list -g for globally installed packages.

You can find the version of a specific package by passing its name as an argument. For example, npm list grunt will result in:

projectName@projectVersion /path/to/project/folder
└── [email protected]

Alternatively, you can just run npm list without passing a package name as an argument to see the versions of all your packages:

├─┬ [email protected]
│ └── [email protected]
├── [email protected]
├── [email protected]
├─┬ [email protected]
│ ├── [email protected]
│ └── [email protected]
└── [email protected]

You can also add --depth=0 argument to list installed packages without their dependencies.

Answer 2

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

├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
└── [email protected]

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

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

To find out which packages need to be updated, you can use npm outdated -g --depth=0.

Answer 3

npm view <package> version - returns the latest available version on the package.

npm list --depth=0 - returns versions of all installed modules without dependencies.

npm list - returns versions of all modules and dependencies.

And lastly to get the Node.js version: node -v

Answer 4

Use

npm info YOUR_PACKAGE version

E.g.,

npm info grunt version

0.4.5

Answer 5

From the root of the package do:

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

(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>.)

Answer 6

I just used

npm list | grep <package name>

and it worked great.

On Windows, run:

npm list | find <package name>

In PowerShell run:

npm list | sls <package name>

Answer 7

For local packages:

npm list --depth=0

For global packages:

npm list -g --depth=0

Answer 8

You can see file package.json to see installed packages versions.

To get the list on the command line,

npm ls

It will give you all installed packages in a project with their respective versions.

For a particular package version,

npm ls <package-name>

For example,

npm ls next

It will return version

-- [email protected]

Answer 9

WARNING: This answer shows the latest available version of a module in npm, not the currently installed version locally.

---

It's very simple.. Just type the below line

npm view <package-name> version

Example

npm view redux version

I have version 7.2.0 of Redux.

Answer 10

Combining some of the above answers and produces a super simple and super quick lookup.

Run from the project root. There isn’t any need to cd into any folder, just one line:

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

Answer 11

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

Output:

0.4.2

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

Output:

0.4.2

Answer 12

You can also check the version with this command:

npm info <package name> version

Answer 13

I've seen some very creative answers, but you can just do this (for global packages add the --global switch):

npm ls package

Example:

npm ls babel-cli

Output:

`-- [email protected]

The npm documentation says that npm -ls

This command will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure.

NPM documentation

Answer 14

If you are brave enough (and have Node.js installed), you can always do something like:

echo "console.log(require('./package.json').version);" | node

This will print the version of the current package. You can also modify it to go insane, like this:

echo "eval('var result='+require('child_process').execSync('npm version',{encoding:'utf8'})); console.log(result.WHATEVER_PACKAGE_NAME);" | node

That will print the version of WHATEVER_PACKAGE_NAME package, that is seen by npm version.

Answer 15

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

Answer 16

To list local packages with the version number use:

npm ls --depth=0

To list global packages with the version number use:

npm ls -g --depth=0

Answer 17

npm list --depth 0 is the command which shows all libraries with version, but you can use npm-check.

npm-check is a good library to manage all those things regarding the version system event. It will show libraries versions, new version updates, and unused versions, and many more.

To install it, just run:

npm install -g npm-check

And simply run

npm-check

Check the screenshot. It is showing everything about the package versions, new version updates, and unused versions.

It works globally too. Give it a try.

Answer 18

I've built a tool that does exactly that - qnm.

qnm - A simple CLI utility for querying the node_modules directory.

Install it using:

npm i --global qnm

And run:

qnm [module]

For example:

qnm lodash

Output:

lodash
├── 4.17.5
├─┬ cli-table2
│ └── 3.10.1
└─┬ karma
  └── 3.10.1

Which means we have lodash installed in the root of the node_modules folder folder and two other copies in the node_modules folder of cli-table2 and karma.

It's really fast and has some nice features, like tab completion and match search.

Answer 19

npm list package-name gives the currently installed version

Answer 20

Try with:

npm list --depth 1 --global packagename

Answer 21

Here's a portable Unix (using grep and sed) one-liner that returns the version string of a globally-installed npm package (remove the g from -pg to query local packages instead):

npm ll -pg --depth=0 grunt | grep -o "@.*:" | sed 's/.$//; s/^.//'

Output:

0.4.5

• the npm ll outputs a parsable string formatted like: /usr/lib/node_modules/npm:[email protected]:;
• the grep command extracts the value between @ and :, inclusive;
• the sed command removes the surrounding characters.

Answer 22

I added this to my .bashrc file:

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 the same thing
       ;;
       *) echo 'Invalid arguments';
       ;;
       esac;
    ;;
    *) echo 'Invalid arguments';
    ;;
    esac;
}
export -f npmv

Now all I have to do is type:

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

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

Answer 23

This is a simple question and should have a simpler answer than what I see in previous answers.

To see the installed npm packages with their version, the command is npm ls --depth=0, which, by default, displays what is installed locally. To see the globally installed packages, add the -global argument: npm ls --depth=0 -global.

--depth=0 returns a list of installed packages without their dependencies, which is what you're wanting to do most of the time.

ls is the name of the command, and list is an alias for ls.

Answer 24

If you'd like to check for a particular module installed globally, on Unix-like systems use:

npm list -g --depth=0 | grep <module_name>

Answer 25

To get only the installed version number, try:

npm list --depth=0 packagename | grep packagename | cut -d'@' -f2

E.g., the installed version number of PM2:

npm list --depth=0 pm2 | grep pm2 | cut -d'@' -f2

And to list globally installed packages, add the -g flag to the npm list command, eg:

npm list -g --depth=0 packagename | grep packagename | cut -d'@' -f2

Answer 26

I am using

npm list --depth=0 | grep module_name@

It brings me results like this:

[email protected]

Answer 27

Access the package.json file

You can access the package.json or bower.json file of the package with:

Windows (with notepad installed):

notepad ./node_modules/vue-template-compiler/package.json`

This will open the package.json in Notepad which has the version number of the packageName you included in the command.

Mac/Linux:

cat node_modules/prettier/package.json | grep version

This will output something like this:

Answer 28

Run the following command to list the installed packages and their versions:

For a specific project (locally):

npm list

For a global package (globally installed):

npm list -g

If you want to find the version of a specific package, you can specify its name:

For a specific project (locally):

npm list <package-name>

For a global package (globally installed):

npm list -g <package-name>

This will display a tree-like structure of all the installed packages and their versions in your project or globally. Look for the package you're interested in, and its version should be displayed next to its name.

Answer 29

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.

Answer 30

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
