Sending Emails with Node.js using Nodemailer

What is Nodemailer ?

Nodemailer is a module for Node.js that simplifies the process of sending emails from a Node.js application. It provides an easy-to-use API for composing and sending emails using various email services and transport methods. With Nodemailer, you can send plain text emails, HTML emails, and even attachments.

Install Nodemailer

Use the following command to install nodemailer :

npm install nodemailer
Enter fullscreen mode Exit fullscreen mode

Configure Nodemailer 

Below is an example of configuring Nodemailer with Gmail using the SMTP (Simple Mail Transfer Protocol).

const nodemailer = require('nodemailer');

// Create a transporter object using Gmail SMTP
const transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        user: 'your-email@gmail.com',
        pass: 'your-email-password'
    }
});

// Additional configuration options
const mailOptions = {
    //...
};

// Send email
transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
        console.error('Error:', error);
    } else {
        console.log('Email sent:', info.response);
    }
});
Enter fullscreen mode Exit fullscreen mode

Additional Configuration Options

You can customise the email further by adding options to the mailOptions object.

const mailOptions = {
    from: 'your-email@gmail.com',
    to: 'recipient-email@example.com',
    subject: 'Test Email',
    text: 'This is a test email sent from Node.js using nodemailer.',
    html: '<p>This is a <b>test</b> email sent from Node.js using nodemailer.</p>',
    attachments: [
        {
            filename: 'attachment.txt',
            content: 'Attachment content'
        }
    ]
};
Enter fullscreen mode Exit fullscreen mode

These options allow you to specify the sender, recipient, subject, email body (both plain text and HTML), and even attachments.

Conclusion 

To wrap it up, Nodemailer is a handy tool in Node.js for sending emails easily. Whether you're just sending simple messages or dealing with more complex email tasks, Nodemailer is flexible enough to handle it. As you use Nodemailer, keep an eye on any updates and best practices to keep your email communication smooth and trouble-free. Enjoy coding!
