How to Send Emails with Node.js and Nodemailer – Tutorial by Mailtrap

Sending emails in Node.js is a common task for many developers. Whether you want to send automatic notifications, newsletters, order confirmations, or any other type of message, Node.js offers a powerful feature set for handling email communications. In this tutorial, we will show you how to use Nodemailer, a popular email sending library, and Mailtrap, an email testing tool, to send emails with Node.js.

Getting Started

First, you’ll need to have Node.js and NPM (Node Package Manager) installed on your machine. You can check if you have them installed by running the following commands in your terminal:

    
      node -v
      npm -v
    
  

If you don’t have them, you can download and install them from the official Node.js website.

Installing Nodemailer and Mailtrap

Once you have Node.js and NPM installed, you can create a new Node.js project and install Nodemailer using the following commands:

    
      mkdir send-email-tutorial
      cd send-email-tutorial
      npm init -y
      npm install nodemailer
    
  

Next, you’ll need to sign up for a Mailtrap account and obtain your SMTP credentials. Once you have your credentials, you can configure Nodemailer to use Mailtrap as your SMTP server. Now, let’s write some code to send an email using Nodemailer:

Sending Emails with Nodemailer

    
      const nodemailer = require('nodemailer');

      // Create a transporter using Mailtrap SMTP settings
      let transporter = nodemailer.createTransport({
        host: 'smtp.mailtrap.io',
        port: 2525,
        auth: {
          user: 'your-mailtrap-username',
          pass: 'your-mailtrap-password'
        }
      });

      // Define the email message
      let mailOptions = {
        from: 'your-email@example.com',
        to: 'recipient@example.com',
        subject: 'Hello from Nodemailer',
        text: 'This is a test email from Nodemailer and Mailtrap!'
      };

      // Send the email
      transporter.sendMail(mailOptions, (error, info) => {
        if (error) {
          console.log(error);
        } else {
          console.log('Email sent: ' + info.response);
        }
      });
    
  

That’s it! You have successfully sent an email using Nodemailer and Mailtrap. You can now use this code as a basis for sending different types of emails in your Node.js applications.
