How to Send e-mail using NodeJS

In this tutorial i am going to discuss about How to Send e-mail using NodeJS. Sending an email in nodejs is a breeze thanks to NodeMailer. Let me walk you through the process of sending an email using NodeMailer.

Nodemailer is a module for Node.js applications to allow easy as cake email sending. The project got started back in 2010 when there was no sane option to send email messages, today it is the solution most Node.js users turn to by default.

Nodemailer is licensed under MIT license. See license details in the License page. If you are upgrading from Nodemailer v2 or older, then see the light migration guide here.

Nodemailer features

• A single module with zero dependencies – code is easily auditable, as there are no dark corners
• Heavy focus on security, no-one likes RCE vulnerabilities
• Unicode support to use any characters, including emoji 💪
• Windows support – you can install it with npm on Windows just like any other module, there are no compiled dependencies. Use it hassle free from Azure or from your Windows box

How to Send e-mail using NodeJS

In this tutorial i am going to discuss about sending e-mail with Node.js. We will use Nodemailer and Gmail account so create a gmail account for this tutorial..

firstly install nodemailer in your node application.

npm install --save nodemailer

after installing the nodemailer, in your main node.js file require the nodemailer

var nodemailer = require('nodemailer');

Nodemailer needs a transport service using which it can send emails. So we use gmail.

Inside your node.js file write

var transporter = nodemailer.createTransport({
 service: 'gmail',
 auth: {
        user: 'youremail@address.com',
        pass: 'yourpassword'
    }
});

The next up is our auth object in which we have to specify our email address and password of Gmail for allowing Nodemailer to login and send email using our gmail account. Now we need a second configuration object where we will be configuring our email details.

const mailOptions = {
  from: 'sender@email.com', // sender address
  to: 'to@email.com', // list of receivers
  subject: 'Subject of your email', // Subject line
  html: '<p>Your html msg here</p>'// plain text body
};

Before sending your email using gmail you have to allow non secure apps to access gmail you can do this by going to your gmail settings here.

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