but following code still errors when starting server:

var express = require('express'); var app = express();  app.use(express.static('resources')); app.use(express.static(__dirname)); app.use(express.bodyparser.urlencoded());  app.get('/', function (req, res) {    res.sendfile( __dirname + "/" + "index.html" ); })  app.post('/java_preview', function (req, res) {     console.log("request java_preivew:");    console.log(req.body.url); })  var server = app.listen(3000, function () {   console.log("server started...")   var host = server.address().address   var port = server.address().port    console.log("listening @ http://%s:%s", host, port) })

any suggestions please

bodyparser not part of express anymore. install dependency npm, , include in project.

var bodyparser = require('body-parser'); app.use(bodyparser.urlencoded({extended : false}));
