如何使用nodejs和express记录应用程序崩溃和系统崩溃？

npm install express

const express = require('express');
const fs = require('fs');

const logFile = fs.createWriteStream('crash.log', { flags: 'a' });

process.on('uncaughtException', (err) => {
  console.error('应用程序崩溃:', err);
  logFile.write(`应用程序崩溃: ${err}\n`);
  logFile.end();
  process.exit(1);
});

process.on('exit', (code) => {
  console.log(`应用程序退出，退出码: ${code}`);
  logFile.write(`应用程序退出，退出码: ${code}\n`);
  logFile.end();
});

const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(port, () => {
  console.log(`应用程序正在监听端口 ${port}`);
});
