node.js怎么监听程序强制退出？

Question

java中可以用Runtime.getRuntime().addShutdownHook();来监听退出事件，所以可以在退出前做一些状态清理的工作,在IDE中强制退出也能捕捉到；

在node.js中我用process.on('exit')为什么不能捕捉到IDE中退出事件呢？

Answer 1

https://nodejs.org/api/process.html#process_event_exit

This event is only emitted when node exits explicitly by process.exit() or implicitly by the event loop draining.

Answer 2

Cannot monitor
Forced exit semaphore cannot add callback function in node

Answer 3

I don’t know what command is sent to force exit in the IDE
In nodejs, you can listen to the exit of the program by listening to the semaphore
For example, SIGINT listens to ctrl-D/Control-C to exit the program

process.on('SIGINT', function() {
  console.log('Got SIGINT.  Press Control-D/Control-C to exit.');
});
