檔案解釋

• jsconfig.json 是用來設定 import 的路徑，這樣就不用一層一層的找檔案了
• package.json 是用來設定套件的版本，以及一些指令
• package-lock.json 是用來記錄套件的版本，不用管他
• public 資料夾是放靜態檔案的地方，例如圖片、網頁的 icon
• src 資料夾是放程式碼的地方
• src/App.js 是 root component，也就是整個網頁的最外層
• src/index.js 是整個網頁的進入點，也就是從這裡開始執行程式
• src/components 資料夾是放 component 的地方，component 是可以重複使用的元件，例如按鈕、表格、輸入框等等
• src/pages 資料夾是放 page 的地方，page 是網頁上的一個頁面，例如首頁、登入頁、註冊頁等等
• src/utils 資料夾是放工具的地方，例如跟伺服器溝通的 API、驗證資料的函式等等
• src/pages/xxx/index.js 是一個頁面的進入點，也就是從這裡開始執行程式

Getting Started with Create React App

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
