How to use html files externally in nodejs (Not internal html)?

I want to send multiple mails by using nodejs. Currently I am using the html code inside the Nodejs script of Route. But when html is going large the Nodejs file also going huge and it is not maintainability.

So how can I use html files externally ?

I am using nodemailer code externally. Like that I also want to use html file externally (/api/htmls/registerEmail.html). But the html file also using body data also (req.body.fname)

mailSender.js (/api/routes/r_msg/)

var nodemailer = require('nodemailer');

function sendMail(to, msg, subject)    
{

  var transporter = nodemailer.createTransport({

  host: 'smtp.zoho.com',
    port: 465,
    secure: true,
    auth: {
      user: '[email protected]',
      pass: 'password'
    }
});

var mailOptions = {
  from: '[email protected]',
  to:to,
  subject: subject,
  html: msg,
};

transporter.sendMail(mailOptions, function(error, info)
{
  if (error)
  {
    console.log(error);
  } 
})

}

module.exports.sendMail = sendMail;

register.js (/api/routes/)

const express = require('express');
const router = express.Router();
const app = express();
const sendMail = require("../api/routes/r_msg");

router.post("/register/new", (req, res) =>
{
    const newStudent = new Student(
    {
        fname: req.body.fname,
        lname: req.body.lname,
        contact_no: req.body.lname,
        email : req.body.email
    });

    newStudent.save()
    .then(student =>
    {
        if (student)
        {
            //This line want to change
            var html = `<html> <body> Hello ` + req.body.fname + `Welcome </body> </html>`;

            sendMail.sendMail(req.body.email, html, 'Success');
            res.status(200).send(setting.status("Success")
            console.log('Email sent: ' + info.response);
        }

    });
}

As mentioned in the comment, you can solve it with ejs.

Add this to your register.js:

const ejs = require('ejs');
const promisify = require('util').promisify;
const renderFile = promisify(ejs.renderFile);

// inside route handler:

renderFile(__dirname + "/api/htmls/registerEmail.html", {fname: req.body.fname})
    .then(html => {
        sendMail.sendMail(req.body.email, html, 'Success');        
    })
    .catch(error => {
        // handle error
    })

Email template registerEmail.html

<html> <body> Hello <%= fname %> Welcome </body> </html>
