This article discusses how to configure nodemailer in your code. Quickly understand the code and implement your code. Let's start
Setup folder structure like this
Packages
express
nodemailer
dotenv
colors
npm i express nodemailer dotenv colors
Create backend folder and inside folder create file is server.js,
Like this backend/server.js
backend/server.js
In this section, we create the express app server, and listen port is 5000.
import express from 'express'; import dotenv from 'dotenv'; import colors from 'colors'; import Router from './router.js'; dotenv.config(); const app = express(); app.use(express.json()); app.use(express.urlencoded({ extended: false })) app.use('/api/contact', Router); const PORT = process.env.PORT || 5000; app.listen(PORT, () => { console.log(`server running ${process.env.NODE_ENV} mode on port ${process.env.PORT}`.yellow.underline); }) backend/router.js
In this section configure the nodemailer and post your email, to email, subject, and message in the route http://localhost:5000/api/contact. Using the Postman really helps test your API. Easily find errors and nodemailer working or not
import express from 'express'; const router = express.Router(); import nodemailer from 'nodemailer'; router.post('/', (req, res) => { const { fromEmail, toEmail, subject, message } = req.body; const output = ` <div style="font-family:'Sen',sans-serif;"> <h3>Subject</h3> <p style="margin-left: 1rem;">${subject}</p> <h3>Message</h3> <p style="margin-left: 1rem;">${message}</p> </div> `; // create reusable transporter object using the default SMTP transport let transporter = nodemailer.createTransport({ service: 'gmail', port: 465, secure: true, // use SSL // true for 465, false for other ports auth: { user: `${fromEmail}`, // generated ethereal user pass: '---------' // generated ethereal password }, tls:{ rejectUnAuthorized:true } }); // setup email data with unicode symbols let mailOptions = { from: `"Contact" <${fromEmail}>`, // sender address to: `${toEmail}`, // list of receivers subject: `${subject}`, // Subject line text: `${message}`, // plain text body html: output // html body }; // send mail with defined transport object transporter.sendMail(mailOptions, (error, info) => { if (error) { return res.status(401).json({ msg: error }); } // console.log('Message sent: %s', info.messageId); // console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info)); if (info) { return res.status(200).json({ msg:`Message has been sent ${toEmail}` }); } }); }) export default router; I trust this article helps your code and understand the configure the nodemailer.
