Sending email using Gmail in NodeJS

Using nodemailer package in NodeJS we can use gmail credentials to send emails programatically.

Following code shows how to do that

const nodemailer = require('nodemailer');

// one time configuration
let mailTransporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: '[email protected]', // repalce this with your email
    pass: 'sender_password'         // replace this with your password
  }
});

function sendEmail(toEmail, subject, body){

  let mailDetails = {
    from: '[email protected]', // repalce this with your email
    to: toEmail,
    subject: subject,
    text: body
  };  
	
  mailTransporter.sendMail(mailDetails,function (err, data) {
    if (err) {
      console.log('email sending failed', err);
    } else {
      console.log('email sent successfully!');
    }
  });
}
