EN

const nodemailer = require('nodemailer');
const ejs = require('ejs');

const user = 'xxx'
const pass = 'xxx';

const transporter = nodemailer.createTransport({
    service: 'gmail',
    auth: { user, pass }
});

const emailPasswordChange = (email, uuid) => {
    ejs.renderFile("./mail/forgot-password.ejs", { uuid }, (err, data) => {

        if (err) return console.log(err)

        let mailOptions = {
            from: 'xxx',
            to: email,
            subject: "Forgot My Password",
            html: data
        };

        transporter.sendMail(mailOptions, (error, info) => {
            if (error) return console.log(error);
        });
    })
}

module.exports.emailPasswordChange = emailPasswordChange;
