hello.js

var express = require('express');
var app = express();

var engine = require('ejs-locals');

app.engine('ejs', engine);
app.set('view engine', 'ejs');
app.set('views', __dirname + '/views');


app.get('/', function(req, res){ 
res.render('index',{user:"John Smith"}) 
 });

app.get('/helo', function(req, res){
  res.send({'data':'hello'});
});


var server = app.listen(3000, function () {

  var host = server.address().address;
  var port = server.address().port;

  console.log('Example app listening at http://%s:%s', host, port);

});

index.ejs in the directory called views---path appname/views/index.ejs

$(document).ready(function(){

            var result = data
