ESlint + StyleLint + Prettier 己經現今前端開發協作相當重要的工具，他可以讓團隊有一致的程式碼風格及規範，並透過 Vscode 開發工具，能夠協助修正一些錯誤。

• ESlint : 程式碼撰寫風格校驗，開發階段找到很多潛在問題。
• StyleLint : CSS 自動校驗是不是符合團隊規範，自動調整成團隊規範的 CSS。
• Prettier: 讓團隊有一致的，自動整理程式碼格式。

建立 next js 應用程式

npx create-next-app@latest --typescript
npm run dev

自動化安裝相關的套件( 專在案目錄執行，可以寫成 powershell )

code --install-extension dbaeumer.vscode-eslint 
code --install-extension [email protected]
code --install-extension esbenp.prettier-vscode
code --install-extension rvest.vs-code-prettier-eslint
cd ..
npm i --save-dev @typescript-eslint/eslint-plugin @typescript-eslint/parser eslint-config-prettier eslint-plugin-prettier eslint-plugin-react prettier prettier-plugin-organize-imports prettier-plugin-tailwindcss  stylelint-config-standard-scss
