建立myserver.js檔案：

myserver.js:

const http = require('http');

const hostname = '127.0.0.1';

const port = 3000;

const server = http.createServer((req,res) => {

res.statusCode = 200;

res.setHeader('Content-Type','text/plain');

res.end('Hello Node.js World.\n');

});

server.listen(port,hostname, () => {

console.log('Server running at http://${hostname}:${port}/');

});

開啟瀏覽器輸入：http://127.0.0.1:3000/

頁面內容：
