需要创建Excel文件并在客户端浏览器中下载-是否可以创建文件流并在Node Express响应中发送它？

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

const app = express();

app.get('/download-excel', async (req, res) => {
  const workbook = new exceljs.Workbook();
  const worksheet = workbook.addWorksheet('Sheet 1');

  // 添加数据到工作表
  worksheet.addRow(['Name', 'Age']);
  worksheet.addRow(['John Doe', 30]);
  worksheet.addRow(['Jane Smith', 25]);

  // 生成Excel文件流
  const filePath = 'temp.xlsx';
  await workbook.xlsx.writeFile(filePath);

  // 发送Excel文件流到客户端浏览器
  res.setHeader('Content-Type', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
  res.setHeader('Content-Disposition', 'attachment; filename=example.xlsx');
  fs.createReadStream(filePath).pipe(res);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
