Get package.json version from CLI

Using Node

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

The -p argument prints the result and the -e argument expects executable JS to follow it. This one is also helpful for getting specific properties from any JSON file.

Using jq

cat ./package.json | jq '.version'

Use the cat program to read the contents of the file and pipe it to the jq program to parse the JSON.
