esbuild OS Notifier Plugin

esbuild-os-notifier (v1.1.1) is a plugin for esbuild that triggers native OS notifications when builds finish, error, or warn. It wraps node-notifier to support macOS, Windows, and Linux. Allows customization of notification content, sound, timeout, and selective enabling of success/error/warning alerts. Currently stable with monthly releases. Differentiators: minimal config, built-in TypeScript types, and simple API compared to alternatives like esbuild-plugin-notify.
