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.
