新手初入nodejs, 有些配置問題請各位指教

index.js
var server = require("./server");
var router = require("./router");
server.start(router.route);

router.js

function route(pathname) {
    console.log("About to route a request for " + pathname);
  }
  
  exports.route = route;

server.js

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

function start(route) {
  function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");

    route(pathname);

    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
  }

  http.createServer(onRequest).listen(8888);
  console.log("Server has started.");
}

exports.start = start;

我要在command prompt 上執行 node index.js ,才可以在chrome 運行 http://localhost:8888

請問如何WEB SERVER 上運行,而不需要輸入 node index.js
可否在IIS 上運行? 因為書本上沒有教如何發行到網上,所以例子都是LOCAL, 謝謝
