用 Express 框架寫一個 Hello World server

提醒：Node.js 的模組採用的是 CommonJS 規範，所以不能寫 import xxx from 'xxx'，要寫 const xxx = require('xxx')。除此之外，因為 Nodejs 更新很快，所以只要是符合 ES 標準的語法都可以使用，不用 babel 轉譯。

Express 是 Nodejs 目前最流行的 web 框架，可以很簡單的架起 API server，試著用 express 架一個 server 監聽 port 3000，直接在 nodejs-basic-practice 裡面建一個 002 的專案，完成以下幾個 API。

GET /api/testing

Response:

"Hello World GET"

POST /api/testing

Response

"Hello World POST"

寫完可以用 Postman 或是 curl 之類的工具測測看
