React（Tailwindcss + TypeScript）の構成でアプリを作成しました【Movie App】

環境の準備

①ターミナルでreactアプリケーションを作成する。

$ npx create-react-app <プロジェクト名> --template typescript
% cd <プロジェクト名>
% yarn start

② 必要な環境を整える。

ESLintとPrettierとを基本からまとめてみた【React＋TypeScriptのアプリにESLintとPrettierを導入】

$ npm i -D tailwindcss postcss autoprefixer
$ npm i tailwind-scrollbar-hide
$ npx tailwindcss init -p

$ yarn add axios
$ yarn add react-router-dom
$ yarn add react-paginate

③不要なファイルを削除する。
