Introduction to NodeMailer and React Email
Sending emails is a common feature in modern web applications, and tools like NodeMailer and React Email make it simple and efficient. NodeMailer handles backend email delivery, while React Email helps you create beautiful, reusable email templates with React components. Together, they provide a powerful solution for managing emails in a Next.js application. Let’s explore how to use them!
Setting Up Your Next.js Project
Before we dive into email functionality, let’s get your Next.js project ready. Start by creating a new Next.js application if you don’t already have one:
Installing NodeMailer and React Email
To enable email functionality, you need to install NodeMailer for handling email delivery and React Email for creating templates. Run the following command in your project directory to install them:
- NodeMailer: Manages email transport and delivery.
- @react-email/components: Provides pre-built React components for designing and rendering email templates.
With these libraries in place, you’re ready to build email-sending logic and design templates directly in your Next.js application!
Configuring NodeMailer
To configure NodeMailer in your Next.js project, create a file named email.ts
inside the server
directory. This file will contain the logic for sending emails.
Creating the Email Configuration
Set Up Environment Variables
Add the following environment variables to your .env
file:
Replace the values with your SMTP server details.
How It Works
- The
getTransporter
function initializes and reuses a single NodeMailer transporter instance for sending emails. - The
sendEmail
function takes in the recipient’s email address, subject, and a React component to render as the email body. - It uses
render
from@react-email/components
to convert the React component into HTML for the email.
With this setup, you’re ready to send beautifully designed emails directly from your Next.js application!
Creating Email Templates with React Email
React Email simplifies building email templates with React components. Let’s create a basic template for testing purposes.
Create a Test Email Template
Create a file named TestEmail.tsx
in a components/emails
folder:
Integrating React Email Components in the Frontend
To trigger email sending via the frontend, integrate React Email with a server action.
Frontend Code
Create a simple form to send a test email.
Testing Email Functionality
Setting Up the Server Action
Create test-email.action.ts
Testing
- Start the Next.js development server:
npm run dev
. - Visit the page with the form and click the "Send Email" button.
- Check the recipient’s inbox for the test email.
This process ensures your email-sending functionality is fully operational!
