How do I get current package's version using only npm

Question

How do I get the current version from package.json using npm?

I know that npm version will output my package's version along with npm and other dependencies. But I need a short command to get only my package version to use on a CI. So ideally, no extra input as the CI doesn't know what project it's dealing with.

npm version from-git --allow-same-version would also work, if it didn't try to tag the new version on Git.

Answer 1

Using npm:

npm -s run env echo '$npm_package_version'

from npm v7.2:

npm pkg get version

Answer 2

There is no direct npm command to show only your package version, but you can use this hack from your project folder:

node -e "console.log(require('./package.json').version);"

If you want to use an npm command you can wrap it into a "script" in your package.json file :

"scripts": {
    "version": "node -e console.log(require('./package.json').version);"
}

Now you can launch npm run version to get your package version
