描述

I imagine it would be something like:

const activeWin  = require('active-win');

activeWin.on('change', win => {
    console.log(win.title);
});

With win being the same as activeWin() returns.

No idea how to achieve this though as it would have to communicate with the binary somehow. Maybe spawn the native binary when someone subscribes to the events, and have the binary push to stdout for each event.

PR welcome 😀

研究方向
Examine the existing native binary used by the module to understand its output format. Investigate how the binary could be run in a long lived process and emit events when the active window changes. Consider using child process.spawn to start the binary and parse its stdout for changes. Look at the existing source code for how activeWin() works to replicate the data structure. The issue's PR welcome indicates maintainer openness, but the approach is unclear.
