我已经创建了一个简单的react
redux应用程序（使用webpack），带有联系表单，当用户单击“提交”时，我想生成并发送电子邮件。为此，我一直试图nodemailer像这样使用：

import nodemailer from 'nodemailer';

//...

sendEmail () {

    const emailInfo = {
        to: 'foo@bar.com',
        from: 'bar@foo.com',
        subject: 'Message from bar',
        text: 'Hello world!'
    };

    const connectionInfo = {
         host: '...',
         port: 123,
         secure: true,
         auth: {
              user: 'foo@bar.com',
              pass: 'foo123'
         }
     };

     const transporter = nodemailer.createTransport('SMTP', connectionInfo);
     transporter.sendMail(emailInfo, function(error){
          if(error){ console.log('error'); }
          console.log('sent');
     });
}

…但是我在nodemailer导入过程中遇到了很多错误。

我是否在这里缺少某些东西，或者nodemailer根本不是为在浏览器中使用而设计的？如果是这种情况，我应该考虑其他选择吗？
