autoupdater is a small Node.js library that lets command‑line npm packages automatically check for and install newer versions in the background. By wrapping a package’s package.json with the `AutoUpdate` class, CLI tools can receive `update` and `finish` events to inform users when an update starts and completes, using the proven `update-notifier` under the hood. It’s aimed at developers building CLI npm modules who want seamless self‑updating functionality.
