version

version

Semantic Version (semver) of either the Command or, most often, the CLI or utility it resides in.

For more information on semantic versioning, see their docs at semver.org.

--version Flag​

If version is set and the autoVersion property isn't set to false, running your command with the --version (or its alias, -v) will output the version:

new Command({
  name: 'my-command',
  version: '0.6.2'
})
$ my-command --version
0.6.2

Common Usage​

When building a CLI or a command that contains subcommands, the version is set in the primary command. This will give users an indication of the version of the entire command structure. A common practice is to import/require the project's package.json and apply the version from there, so it doesn't have to be manually updated in the code.
