Generally, you'd want some kind of emailing api; I personally use Twilio's SendGrid api (very easy to set up and implement). Using this api, you'd construct and send a url (the email verification url) from the back end register route. The implementation is as simple as: 

const sgMail = require('@sendgrid/mail');


sgMail.setApiKey(process.env.SENDGRID_API_KEY);

const link = 'http://'+req.headers.host+'/api/users/register/verifyEmail/'+token;

const htmlContent = 'some html content';

const msg = {
    to: newUser.email,
    from: process.env.VALIDATION_EMAIL_SENDER,
    subject: 'Some email subject',
    html: htmlContent,
};

sgMail.send(msg, (err) => {
    if(Object.entries(err).length > 0) {
            return res.status(500).json({success: false, msg: "Something went wrong; can't send validation email.", err});
    }

    res.status(200).json({success: true, msg: "Check your email and verify account to 
    proceed.", user: {newUser});
});

then you'll have another backend route which verifies the validity of the link by which ever criteria you decide.

Outside router function

function validateEmail(email) {

 var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
  return re.test(email);
}

Inside router function

if (validateEmail(req.body.email)) {
   console.log('valid email');
  } else {
   console.log('invalid email');
  }

You can use alternative libraries like express validator that do the same job.
