Send Emails With Node.js. In this article, I will discuss sending e-mail with Node.js. I’ve covered Express.js tutorials and I will also use NodeMailer in this article. For the verification, password recovery and promotion of account, many forums and blogs asked people about the sending of emails with Node.js. So let’s start with a tutorial and at the end there is a node app that can send e-mails to any account.

Nodemailer is a Node.js module for easy to send e-mail like cake. The project started in 2010, when it wasn’t possible to send E-mails, today it’s the default solution for the majority of Node.js users.

Step -1: You need to install NodeMailer package to your node application

npm install --save nodemailer

Step-2: You need to require nodeMailer in your route file

const nodeMailer = require('nodemailer');

Now, use the standard SMTP transport to generate transporter object that can send messages. In this example, I will use gmail SMTP to send Emails With Node.js

Step-3: Create transporter object using the default SMTP transport 

let transporter = nodemailer.createTransport({
service: ‘gmail’,
host: ‘smtp.gmail.com’,
secure: ‘true’,
port: ‘465’,
auth: {
user: 'youremail@gmail.com',
pass: 'yourpassword'
     }
});

In auth object replace details with your email address and password.

Step-4: We now need to configure the information of our email.



// setup email data 

        let mailOptions = {

            from: '"Your Name" ', // sender address
            to: 'myfriend@gmail.com', // list of receiver
            subject: 'Sending Email using Node.js', // Subject line
            text: 'Hello world', // plain text body
          
        };

At the last we will ‘sendMail()’ method provided by the transporter object we created to send the email.

To send HTML formatted text in your email, use the “html” property instead of the “text” property: 

// setup email data 

        let mailOptions = {

            from: '"Your Name" ', // sender address
            to: 'myfriend@gmail.com', // list of receiver
            subject: 'Sending Email using Node.js', // Subject line
           html: '
Hello World
That was easy!
' // html body
          
        };

To send an email to more than one users, add them to the “to” property of the mailOptions object, separated by commas:

 to: ‘myfriend@gmail.com, myotherfriend@gmail.com‘,

Step-5: Sending the email using ‘sendMail()’ method provided by the transporter object 

transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
});

‘sendMail()’ method requires two argument mailOptions and a callback function which will be called when the mail is sent. The callback function will be called when either email sent successfully or an error occurred.

Complete Code: send Emails With Node.js

var nodemailer = require('nodemailer');

let transporter = nodemailer.createTransport({
service: ‘gmail’,
host: ‘smtp.gmail.com’,
secure: ‘true’,
port: ‘465’,
auth: {
user: 'youremail@gmail.com',
pass: 'yourpassword'
     }
});

let mailOptions = {

            from: '"Your Name" ', // sender address
            to: 'myfriend@gmail.com, // list of receivers
            subject: 'Sending Email using Node.js', // Subject line
            text: 'Hello world', // plain text body
          
        };

transporter.sendMail(mailOptions, function(error, info){
  if (error) {
    console.log(error);
  } else {
    console.log('Email sent: ' + info.response);
  }
