CLI Update Notifier (CommonJS)

update-notifier-cjs is a JavaScript library designed to provide non-intrusive update notifications for Command Line Interface (CLI) applications. Currently at version 5.1.7, it is specifically maintained for CommonJS (CJS) environments, providing a direct alternative to `update-notifier` for projects that do not use ES Modules. The library works by asynchronously checking for package updates against the npm registry in a detached child process, ensuring no impact on the CLI tool's startup performance. It persists the check results and displays notifications only after a configurable interval (defaulting to one day), preventing frequent interruptions to the user. This design choice aims to be user-friendly by avoiding immediate notifications on first run or every execution.
