If you need to send dynamic HTML emails, consider using templating engines like Handlebars or EJS. Here’s how you might use Handlebars with Nodemailer:
Install the required packages:
npm install handlebars nodemailer-express-handlebars
Set up Nodemailer with Handlebars:
const nodemailer = require('nodemailer');
const path = require('path');
const hbs = require('nodemailer-express-handlebars');
// Create a transporter object
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: process.env.EMAIL_USER,
pass: process.env.EMAIL_PASS
}
});
// Set up Handlebars
transporter.use('compile', hbs({
viewEngine: {
extName: '.hbs',
partialsDir: path.resolve('./views/'),
layoutsDir: path.resolve('./views/'),
defaultLayout: 'email'
},
viewPath: path.resolve('./views/'),
extName: '.hbs'
}));
// Email options
let mailOptions = {
from: '"Your Name" <[email protected]>',
to: '[email protected]',
subject: 'Hello with Handlebars',
template: 'email', // Name of the template file (email.hbs)
context: { // Data to pass to the template
name: 'Recipient',
message: 'This is a test email using Handlebars!'
}
};
// Send email
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.error('Error sending email:', error);
}
console.log('Email sent successfully:', info.response);
});
Template file (views/email.hbs):
<!DOCTYPE html>
<html>
<head>
<title>{{subject}}</title>
</head>
<body>
<h1>Hello, {{name}}!</h1>
<p>{{message}}</p>
</body>
</html>
