Node.js - 监听系统进程

Question

我正在寻找一种方法来检测何时使用 node.js 在我的计算机上启动特定进程。

我想要像 discord 一样的东西：当我开始游戏时，我希望我的应用程序能够检测到该游戏。

我在 child_process 环境和 Discord API 中进行了搜索，但没有发现任何可利用的东西

你可以使用chokidar:

const chokidar = require('chokidar');

// Initialize watcher.
const watcher = chokidar.watch('path/to/folder', { persistent: true });
 
// Add event listeners.
watcher
  .on('add', path => log(`File ${path} has been added`))
  .on('change', path => log(`File ${path} has been changed`))
  .on('unlink', path => log(`File ${path} has been removed`));
 
// More possible events.
watcher
  .on('addDir', path => log(`Directory ${path} has been added`))
  .on('unlinkDir', path => log(`Directory ${path} has been removed`))
  .on('error', error => log(`Watcher error: ${error}`))
  .on('ready', () => log('Initial scan complete. Ready for changes'))
