To implement SMTP and IMAP in Node.js, you can use libraries like nodemailer for sending emails using SMTP and imap for accessing emails using IMAP. Here is a basic example of how you can implement SMTP and IMAP in Node.js:

  1. Install nodemailer and imap libraries:
1
npm install nodemailer imap

const nodemailer = require('nodemailer');

// create a nodemailer transporter
let transporter = nodemailer.createTransport({
    service: 'Gmail',
    auth: {
        user: '[email protected]',
        pass: 'your_password'
    }
});

// setup email data
let mailOptions = {
    from: '[email protected]',
    to: '[email protected]',
    subject: 'Hello from Node.js',
    text: 'This is a test email sent from Node.js'
};

// send mail with defined transport object
transporter.sendMail(mailOptions, (error, info) => {
    if (error) {
        return console.log(error);
    }
    console.log('Message sent: %s', info.messageId);
});

const Imap = require('imap');

// create an IMAP connection
let imap = new Imap({
    user: '[email protected]',
    password: 'your_password',
    host: 'imap.gmail.com',
    port: 993,
    tls: true
});

imap.connect();

imap.once('ready', () => {
    imap.openBox('INBOX', false, (error, mailbox) => {
        if (error) {
            console.log(error);
            return;
        }

        // search for all emails
        imap.search(['ALL'], (error, results) => {
            if (error) {
                console.log(error);
                return;
            }

            let f = imap.fetch(results, { bodies: '' });
            f.on('message', (msg, seqno) => {
                console.log('Message #%d', seqno);

                msg.on('body', (stream, info) => {
                    let buffer = '';
                    stream.on('data', (chunk) => {
                        buffer += chunk.toString('utf8');
                    });
                    stream.once('end', () => {
                        console.log(buffer);
                    });
                });
            });
        });
    });
});

imap.once('error', (error) => {
    console.log(error);
});

imap.once('end', () => {
    console.log('Connection ended');
});


Please note that you should replace [email protected] and your_password with your own Gmail credentials. Additionally, you may need to enable less secure apps access in your Gmail account settings for this code to work.
