app.get('/',function(req,res){
res.sendFile(path.join(__dirname+'/index.html'));
//__dirname : It will resolve to your project folder.
});
// port must be set to 8080 because incoming http requests are routed from port 80 to port 8080
app.listen(3000, function () {
console.log('Node app is running on port 3000');
