node-notifier is a Node.js module for sending cross-platform native notifications to macOS, Windows, and Linux systems.
The module solves the problem of displaying system notifications from Node.js applications without requiring platform-specific code. It abstracts away the differences between notification systems across operating systems by automatically selecting the appropriate native notification mechanism for each platform: Notification Center on macOS, notify-osd or libnotify-bin on Linux, and Toasters or taskbar balloons on Windows, with Growl as a fallback when native options are unavailable. The tool wraps existing system notification tools and exposes their capabilities through a unified JavaScript API.
Developers should choose this module when building Node.js applications that need to alert users through system notifications without managing platform-specific implementations. It works particularly well with Electron applications. The module supports advanced features including interactive actions on Windows notifications and fine-grained control over individual platform reporters, allowing developers to customize notification behavior per system if needed. The API mirrors terminal-notifier's parameter structure, so any capability available in that tool can be accessed by passing corresponding properties to the notify method.
The project maintains active engagement with cross-platform compatibility concerns, evidenced by its detailed decision flow documentation for reporter selection and explicit handling of version requirements across different operating systems. Development activity shows responsiveness to community contributions through participation in organized contribution events. The codebase demonstrates sustained attention to both the primary notification use case and secondary features like listing and activating notifications, though these remain undocumented as they fall outside the module's primary focus.
