process.on('exit', async () => {
    require('fs').writeFileSync('./tmp.js', 'crash', 'utf-8')
});

Async-exit-hook似乎是处理这个问题的最新解决方案。它是退出钩子的分叉/重写版本，在退出前支持异步代码。

"exit"是一个在节点内部完成它的事件循环时触发的事件，当你在外部终止进程时不会触发。

你要做的是在SIGINT上执行一些东西。

http://nodejs.org/api/process.html#process_signal_events上的文档给出了一个例子:

监听SIGINT的例子:

// Start reading from stdin so we don't exit.
process.stdin.resume();

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

注意:这似乎会中断sigint，当你完成代码时，你需要调用process.exit()。

更新:

You can register a handler for `process.on('exit')` and in any other case(`SIGINT` or unhandled exception) to call `process.exit()`

process.stdin.resume();//so the program will not close instantly

function exitHandler(options, exitCode) {
    if (options.cleanup) console.log('clean');
    if (exitCode || exitCode === 0) console.log(exitCode);
    if (options.exit) process.exit();
}

//do something when app is closing
process.on('exit', exitHandler.bind(null,{cleanup:true}));

//catches ctrl+c event
process.on('SIGINT', exitHandler.bind(null, {exit:true}));

// catches "kill pid" (for example: nodemon restart)
process.on('SIGUSR1', exitHandler.bind(null, {exit:true}));
process.on('SIGUSR2', exitHandler.bind(null, {exit:true}));

//catches uncaught exceptions
process.on('uncaughtException', exitHandler.bind(null, {exit:true}));

只有在处理程序内部调用同步代码时，这才有效，否则它将无限期地调用处理程序

function fnAsyncTest(callback) {
    require('fs').writeFile('async.txt', 'bye!', callback);
}

function fnSyncTest() {
    for (var i = 0; i < 10; i++) {}
}

function killProcess() {

    if (process.exitTimeoutId) {
        return;
    }

    process.exitTimeoutId = setTimeout(() => process.exit, 5000);
    console.log('process will exit in 5 seconds');

    fnAsyncTest(function() {
        console.log('async op. done', arguments);
    });

    if (!fnSyncTest()) {
        console.log('sync op. done');
    }
}

// https://nodejs.org/api/process.html#process_signal_events
process.on('SIGTERM', killProcess);
process.on('SIGINT', killProcess);

process.on('uncaughtException', function(e) {

    console.log('[uncaughtException] app will be terminated: ', e.stack);

    killProcess();
    /**
     * @https://nodejs.org/api/process.html#process_event_uncaughtexception
     *  
     * 'uncaughtException' should be used to perform synchronous cleanup before shutting down the process. 
     * It is not safe to resume normal operation after 'uncaughtException'. 
     * If you do use it, restart your application after every unhandled exception!
     * 
     * You have been warned.
     */
});

console.log('App is running...');
console.log('Try to press CTRL+C or SIGNAL the process with PID: ', process.pid);

process.stdin.resume();
// just for testing
