Nodemailer with email-templates not sending email

I'm using nodemailer with npm package email-templates. I'm not getting email. Template is working when i set preview:true. Getting error on console Error: No recipients defined.Why this error coming? Tried many things but nodemailer is sending empty email every time. Hope you understand my issue.

Error:

My directory structure:

├── app.js
└── emails
    └── forget-password
        ├── html.pug
        ├── subject.pug

Node mailer with template:

const nodemailer = require('nodemailer');
var generator = require('generate-password');

const Email = require('email-templates');

exports.sendNodeForgotPasswordMail = function (email, GeneratePassword) {
    var transporter = nodemailer.createTransport({
        host: 'smtp.gmail.com',
        port: 587,
        secure: false,
        auth: {
            user: 'my_email',
            pass: 'my_password'
        },
        tls: {
            rejectUnauthorized: false
        }

    });

    const emailVar = new Email({
        message: {
            from: 'testing@gmail.com'
        },
        preview: true,
        send: true,
        transport: {
            jsonTransport: true
        }
    });

    emailVar.send({
        template: 'forget-password',
        message: {
            to: email
        },
        locals: {
            password: GeneratePassword
        }
    }) .then(res => {
        console.log('res.originalMessage', res.originalMessage)
    }).catch(console.error);


    return transporter.sendMail(emailVar, function (err, info) {
        if (err)
            console.log(err);
        else
            console.log(info);
    });
};

Html.pug:

p Your new password is: #{password}

subject.pug

= `Password reset request`

the reason is that you dont need to require nodemailer instead of make your transporter with nodemailer you need to pass it in JSON like so.

exports.sendNodeForgotPasswordMail = function (email, GeneratePassword) {
    var transporter = nodemailer.createTransport({
        host: 'smtp.gmail.com',
        port: 587,
        secure: false,
        auth: {
            user: 'my_email',
            pass: 'my_password'
        },
        tls: {
            rejectUnauthorized: false
        }

    });

becomes:

transport: {
        host: 'smtp.gmail.com',
        port: 587,
        secure: false,
        auth: {
            user: 'my_email',
            pass: 'my_password'
        },
        tls: {
            rejectUnauthorized: false
        }

    }

const Email = require('email-templates'); <-- with this is enough.

If anyone else is looking how to solve this, i manage to make it work based on @Irving Caarmal answer and the code is the following:

function sendTokenEmail(userEmail, token, templateName) {
  const email = new Email({
    message: {
      from: 'someemail@gmail.com',
    },
    preview: true,
    send: true,
    transport: {
      host: process.env.MAIL_HOST,
      port: process.env.MAIL_PORT,
      auth: {
        user: process.env.MAIL_USER,
        pass: process.env.MAIL_PASS,
      },
    },
  })

  return email
    .send({
      template: templateName,
      message: {
        to: userEmail,
      },
      locals: {
        token,
      },
    })
    .then((res) => {
      console.log('res.originalMessage', res.originalMessage)
    })
   }

**得分**: 1

如果有人在获取生成的邮件时遇到问题，您应该在级别上添加`send: true`以及选项`preview: false`（PS：这对我有效），否则即使文档说：

如果您想在开发或测试环境中发送电子邮件，请将options.send设置为true。

**示例：**

```javascript
const email = new Email({
  message: {
    from: process.env.SMTP_USER,
  },
  send: true,
  preview: false,
  transport: {
    host: process.env.SMTP_HOST,
    auth: {
      user: process.env.SMTP_USER,
      pass: process.env.SMTP_PASS,
    },
  },
})

await email.send({
  template: 'template-of-choice',
  message: {
    from: 'email-address',
  },
  locales: {},
})

希望对您有所帮助

const email = new Email({
  message: {
    from: process.env.SMTP_USER,
  },
  send: true,
  preview: false,
  transport: {
    host: process.env.SMTP_HOST,
      auth: {
             user: process.env.SMTP_USER,
             pass: process.env.SMTP_PASS,
   },
  },
})

await email.send({
  template: 'template-of-choice', 
  message: {
    from: 'email-address'
  },
  locales: {}
})
