Sending an Email with Nodemailer in Node.js | Watch Hindi Tutorial on Nodemailer Email Sending

Nodemailer is a popular Node.js module that allows you to send emails from your Node.js application. In this tutorial, we will learn how to send an email using Nodemailer in Node.js.

Step 1: Install Nodemailer
First, you need to install Nodemailer in your Node.js application. You can do this by running the following command in your terminal:

npm install nodemailer

Step 2: Set up your email configuration
Next, you need to set up your email configuration. You will need to provide your email service provider’s SMTP (Simple Mail Transfer Protocol) server details, username, and password. In this tutorial, we will use Gmail as our email service provider.

const nodemailer = require('nodemailer');

// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: 'your_email@gmail.com',
        pass: 'your_email_password'
    }
});

Step 3: Create and send the email
Now, you can create an email message and send it using the sendMail method of the transporter object.

// setup email data with unicode symbols
let mailOptions = {
    from: 'your_email@gmail.com', // sender address
    to: 'recipient_email@example.com', // list of receivers
    subject: 'Hello ✔', // Subject line
    text: 'Hello world?', // plain text body
    html: '<b>Hello world?</b>' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
        return console.log(error);
    }
    console.log('Message %s sent: %s', info.messageId, info.response);
});

Step 4: Test your email sending functionality
You can now run your Node.js application and test if the email is being sent successfully using Nodemailer.

node app.js

If everything is set up correctly, you should see a message in the console indicating that the email has been sent successfully.

In this tutorial, we learned how to send an email using Nodemailer in Node.js. Nodemailer is a powerful module that allows you to send emails from your Node.js application easily. You can customize your email message further by setting various options such as subject, text, and html body.
