This tracker can be used to listen to active window changes on any platform (MacOS, Windows, and Linux)

Add this git repository to your project as a git submodule

git submodule add https://github.com/HASEL-UZH/PA.WindowsActivityTracker

Install the package by adding to package.json and running npm install

npm i ./PA.WindowsActivityTracker/typescript

The simplest example looks as follows

import { WindowsActivityTracker } from "windows-activity-tracker";

const tracker = new WindowsActivityTracker(function (activeWin) {
  console.log(activeWin);
});

tracker.start();

The url field on the ActiveWindow class is currently only supported on MacOS.
