Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine, and Node.js provides an easy way to send emails using its built-in library called nodemailer.
To use nodemailer, you will need to install it first. You can do this by running the following command in your terminal:
npm install nodemailer
Once nodemailer is installed, you can use it to send emails in your Node.js application by requiring the library and creating a transporter object.
const nodemailer = require('nodemailer');
// create a transporter object
const transporter = nodemailer.createTransport({
service: 'gmail', // use a service that allows you to send emails (e.g. Gmail, Outlook, etc.)
auth: {
user: 'your@email.com', // your email address
pass: 'yourpassword' // your email password
}
});
Next, you can use the transporter object to send an email by calling the sendMail function and passing it an object with the email details.
const mailOptions = {
from: '"Your Name" <your@email.com>', // sender address
to: 'recipient@email.com', // list of receivers
subject: 'Subject Line', // Subject line
text: 'Plain text content', // plain text body
html: '<b>HTML</b> content' // html body
};
// send the email
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
That's it! You can now send emails using Node.js and nodemailer.
Here is the full code example:
const nodemailer = require('nodemailer');
// create a transporter object
const transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'your@email.com',
pass: 'yourpassword'
}
});
const mailOptions = {
from: '"Your Name" <your@email.com>',
to: 'recipient@email.com',
subject: 'Subject Line',
text: 'Plain text content',
html: '<b>HTML</b> content'
};
// send the email
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
Here is an example of how you can use nodemailer with
Reactto send emails from a form:
import { useState } from 'react';
import nodemailer from 'nodemailer';
function ContactForm() {
const [formState, setFormState] = useState({
name: '',
email: '',
subject: '',
message: ''
});
const [errorMessage, setErrorMessage] = useState('');
const handleChange = event => {
setFormState({
...formState,
[event.target.name]: event.target.value
});
};
const handleSubmit = event => {
event.preventDefault();
if (!formState.name || !formState.email || !formState.subject || !formState.message) {
setErrorMessage('All fields are required.');
return;
}
// create a transporter object
const transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'your@email.com',
pass: 'yourpassword'
}
});
// create the email options
const mailOptions = {
from: `"${formState.name}" <${formState.email}>`,
to: 'recipient@email.com',
subject: formState.subject,
text: formState.message
};
// send the email
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
};
return (
<form onSubmit={handleSubmit}>
<label htmlFor="name">Name:</label>
<input
type="text"
name="name"
value={formState.name}
onChange={handleChange}
/>
{errorMessage && <div>{errorMessage}</div>}
<label htmlFor="email">Email:</label>
<input
type="email"
name="email"
value={formState.email}
onChange={handleChange}
/>
<label htmlFor="subject">Subject:</label>
<input
type="text"
name="subject"
value={formState.subject}
onChange={handleChange}
/>
<label htmlFor="message">Message:</label>
<textarea
name="message"
value={formState.message}
onChange={handleChange}
/>
<button type="submit">Send</button>
</form>
);
}
export default ContactForm;
I hope this helps! Let me know if you have any questions.
