[nodejs] How to catch unknown exception and shutdown the express instance on low level layer

server.js

var express = require('express');
var app = express();
var fs = require('fs');

app.get('/', function(req, res) {
  res.send("hello");
  // Notice: Make any uncaughtException happend on purpose
  fs.readFile('no_such_file.txt', function(err, data) {
    if (err) throw err;
    console.log(data);
  });
});

app.listen(3000, function() {
  console.log('Example app listening on port 3000!');
});

//
// write an uncaught error log just before the system is shut down: 
//
process.on('uncaughtException', (err) => {
  console.error("uncaughtException: err:", err, "\nerr.stack:", err.stack);
  // Here, app instance must be killed for system consistency.
  // if use any process managemer such as Forever, app is restarted perfectly 
  process.abort(); 
});

/*
# start server:
$ node server.js 
or
$ forever start server.js
