I am using [rekuire](https://www.npmjs.com/package/rekuire) npm package instead of [require](https://www.npmjs.com/package/require) just to not mess up with paths and its configuration. So dont get confuseUsage
global.rekuire = require("rekuire");
var express = rekuire("express");
var app = express();
var json2xl = rekuire('json2xl');
var port = 8000;
app.use(express.static(__dirname + '/public'));
app.listen(port, function(err, res){
if(err){
throw err;
}
else{
port = process.env.port || port;
console.log("application running in port " + port);
}
});
app.get('/json2xl', function (req, res) {
