事件：'resize'

¥Event: 'resize'

每当 writeStream.columns 或 writeStream.rows 属性发生更改时，则会触发 'resize' 事件。当调用时，没有参数传给监听器回调。

¥The 'resize' event is emitted whenever either of the writeStream.columns or writeStream.rows properties have changed. No arguments are passed to the listener callback when called.

process.stdout.on('resize', () => {
  console.log('screen size has changed!');
  console.log(`${process.stdout.columns}x${process.stdout.rows}`);
}); 拷贝
