OS support
It works on macOS 10.14+, Linux, and Windows 7+.
Note: On Windows, there isn't a clear notion of a "Window ID". Instead it returns the memory address of the window "handle" in the id property. That "handle" is unique per window, so it can be used to identify them. Read more…
Linux support
Wayland is not supported. For security reasons, Wayland does not provide a way to identify the active window. Read more…
Electron usage
If you use this package in an Electron app that is sandboxed and you want to get the .url property, you need to add the proper entitlements and usage description.
