使用运行nodejs的javascript在事件发生前发送通知

const nodemailer = require('nodemailer');

// 创建一个SMTP传输对象
const transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  port: 587,
  secure: false,
  auth: {
    user: 'your-email@example.com',
    pass: 'your-password'
  }
});

// 创建邮件对象
const mailOptions = {
  from: 'your-email@example.com',
  to: 'recipient@example.com',
  subject: 'Notification',
  text: 'An event is about to happen!'
};

// 发送邮件
transporter.sendMail(mailOptions, (error, info) => {
  if (error) {
    console.log('Error occurred:', error.message);
  } else {
    console.log('Email sent:', info.response);
  }
});
