I have Created a Visual Force Page. When I preview it I could see the what I have created. I am trying to use the VF page to NodeJs .Wanted to see the same functionality in local server. I created a server running on port 3000. When I run the server, the page keeps on loading. Can someone help what is wrong in my code? Thanks in advance.
app.js
const express = require('express')
const jsforce = require('jsforce')
var fs = require('fs');
require('dotenv').config()
const app = express()
const PORT = 3000
const {SF_LOGIN_URL,SF_USERNAME,SF_PASSWORD,SF_TOKEN} = process.env
const conn = new jsforce.Connection({
    loginUrl : SF_LOGIN_URL
})
conn.login(SF_USERNAME,SF_PASSWORD+SF_TOKEN,(err, userinfo)=>{
if(err){
    console.log(err)
}else{
    console.log("user id : "+userinfo.id)
    console.log("Org id : "+userinfo.organizationId)
}
})
app.get('/',(req,res)=>{
    fs.readFile('./index.html', function (err, html) {
        if(err){
            console.log('Script Error'+err)
        }else{
            res.write(html);  
        }
       
    })
 
 
   
})
app.listen(PORT,()=>{
    console.log(`Server is Running at http://localhost:${PORT}`)
})
