http  伺服器 

建 server.js 檔案 -  node server.js  跑起來 -  瀏覽器訪問  http://localhost:8888/  （伺服器控制台觀看訪問次數）

var http = require("http");var count=(function(){  var num=0;  return function(){    num++;    return num;  }}());http.createServer(function (request, response) {  response.writeHead(200, {    "Content-Type": "text/plain"  });  response.write("Hello World");  response.end();  console.log(‘server‘+count());}).listen(8888);

http  伺服器   模組化方式實現

建主檔案 入口  index.js   -   寫模組化功能並匯出對應介面 server.js  -   運行 node index  -  訪問 http://localhost:8888/ 

index.js

var start=require(‘./server‘);start.start();server.js

function handle(request, response) {  response.writeHead(200, {    "Content-Type": "text/plain"  });  response.write("Hello World");  response.end();  console.log(‘server‘ + count());}var count = (function () {  var num = 0;  return function () {    num++;    return num;  }}());var http = require("http");function start(){  http.createServer(handle).listen(8888);  console.log("Server working.");}exports.start = start;
