Nodemailer Security

How to secure the mail address and Password:

Environment Variables (Recommended)

It's good practice to keep your email credentials secure by using environment variables. You can use the dotenv package to manage these variables.

1. Install the dotenv package:

   npm install dotenv

2. Create a .env file in your project root and add your credentials:

   EMAIL=your-email@gmail.com
   PASSWORD=your-email-password

3. Modify your sendEmail.js file to use dotenv:

   const nodemailer = require('nodemailer');
   require('dotenv').config();
   
   // Create a transporter object
   let transporter = nodemailer.createTransport({
       service: 'gmail',
       auth: {
           user: process.env.EMAIL,
           pass: process.env.PASSWORD
       }
   });
   
   // Define email options
   let mailOptions = {
       from: process.env.EMAIL,
       to: 'recipient@example.com',
       subject: 'Test Email',
       text: 'Hello, this is a test email sent using Nodemailer!',
       html: '<b>Hello, this is a test email sent using Nodemailer!</b>'
   };
   
   // Send the email
   transporter.sendMail(mailOptions, (error, info) => {
       if (error) {
           return console.log(error);
       }
       console.log('Email sent: ' + info.response);
   });
