"Upgradable" runs in a background child process and checks for updates in your CLI package. If there's a new version available - at end of interaction, when user sends interrupt signal (ctrl+c), it will prompt your users to upgrade your node CLI tool.
Use
const upgradable = require('upgradable');
const { name, version } = require('./package.json');
upgradable({name, version});Shorthand
require('upgradable')(require('./package.json'));
upgradable({name, version, message: 'This is my own inspirational message'});
