Nodejs / Express - Launching my app: express.createServer() is deprecated

Question

I downloaded a node app to test and play around with. I have googled around and found that Express is found to be a little outdated. Can someone help me to fix the implement

Answer 1

I am already using the following snippet and it is working fine:

var express =require("express");
var http = require("http");

var app = express();
//app routers here 
...
var httpServer = http.Server(app);

httpServer.listen({PORT}, function(err){

});
