Let’s start!

Assuming you’ve already installed Node.js. For checking use node -v

Step 1

install pakage.json in your project file with this command

npm init

Step 2

For sending mail with node.js we use Nodemailer which is

(Nodemailer is a module for Node.js applications to allow easy as-cake email sending)

for more visit - nodemailer.com/about

npm install nodemailer

Step 3

File Require the nodemailer

Let's code

const nodemailer = require('nodemailer')
const transporter  = nodemailer.createTransport({
service:'gmail',
auth:{   
      user:'Your emalil', // Your Gmail ID
      pass:'Your password'  // Your Gmail Password
      }
})

transporter is going to be an object that can send mail.

Create Transporter Object: A createTransport method in nodemailer that accepts an object with some configurations and finally returns a transporter object.

// Deifne options like Sender Email and Receiver.
const mailOption = {
   from:"sender mail address",
   to:"receiver address", //also add multiple receiver 
   Subj:"",  
   text:"Helo wold",  // Mail Subject
   html: "<b>Hello world?</b>", // html body
   attachments: [
    {
      filename: 'text.txt',
      content: 'Hello world !',
      path: 'https:....' 
  }]
  }

// Send an Email 

transporter.sendMail(mailOption,(err)=>{
     if(err) console.log(err);
     else console.log(info);
 });

Deliver the message object using the sendMail() method
Open your terminal and run your project file and see the Output.
