(react) Todo List App 단계별 만들기

React 관련 주변 기본적인 지식은 어느정도 둘러봤으니 이제 투두리스트 앱을 만들어보면서 감을 올려보도록 해보겠음~

사용할 에디터는 마소에서 만들어준 vscode! ㅎㅎ

 

 

1. 프로젝트 설정

1-1. "todo-app"이라는 이름의 프로젝트를 생성

npx create-react-app todo-app

 

 

 

 

1-2. "todo-app" 폴더로 이동

cd todo-app

 

 

 

 

1-3. 개발서버 구동

npm start

 

 

 

 

1-4. 브라우저에 기본 react app 시작페이지 표시됨.

 

 

 

 

 

 

2. src/App.js 파일 수정

"src폴더 ＞ App.js파일"에 있는 App()함수를 모두 지우고 아래 코드를 복붙해줌~

function App(props) {
  return (
    <div className="todoapp stack-large">
      <h1>TodoMatic</h1>
      <form>
        <h2 className="label-wrapper">
          <label htmlFor="new-todo-input" className="label__lg">
            What needs to be done?
          </label>
        </h2>
        <input
          type="text"
          id="new-todo-input"
          className="input input__lg"
          name="text"
          autoComplete="off"
        />
        <button type="submit" className="btn btn__primary btn__lg">
          Add
        </button>
      </form>
      <div className="filters btn-group stack-exception">
        <button type="button" className="btn toggle-btn" aria-pressed="true">
          <span className="visually-hidden">Show </span>
          <span>all</span>
          <span className="visually-hidden"> tasks</span>
        </button>
        <button type="button" className="btn toggle-btn" aria-pressed="false">
          <span className="visually-hidden">Show </span>
          <span>Active</span>
          <span className="visually-hidden"> tasks</span>
        </button>
        <button type="button" className="btn toggle-btn" aria-pressed="false">
          <span className="visually-hidden">Show </span>
          <span>Completed</span>
          <span className="visually-hidden"> tasks</span>
        </button>
      </div>
      <h2 id="list-heading">3 tasks remaining</h2>
      <ul
        role="list"
        className="todo-list stack-large stack-exception"
        aria-labelledby="list-heading">
        <li className="todo stack-small">
          <div className="c-cb">
            <input id="todo-0" type="checkbox" defaultChecked={true} />
            <label className="todo-label" htmlFor="todo-0">
              Eat
            </label>
          </div>
          <div className="btn-group">
            <button type="button" className="btn">
              Edit <span className="visually-hidden">Eat</span>
            </button>
            <button type="button" className="btn btn__danger">
              Delete <span className="visually-hidden">Eat</span>
            </button>
          </div>
        </li>
        <li className="todo stack-small">
          <div className="c-cb">
            <input id="todo-1" type="checkbox" />
            <label className="todo-label" htmlFor="todo-1">
              Sleep
            </label>
          </div>
          <div className="btn-group">
            <button type="button" className="btn">
              Edit <span className="visually-hidden">Sleep</span>
            </button>
            <button type="button" className="btn btn__danger">
              Delete <span className="visually-hidden">Sleep</span>
            </button>
          </div>
        </li>
        <li className="todo stack-small">
          <div className="c-cb">
            <input id="todo-2" type="checkbox" />
            <label className="todo-label" htmlFor="todo-2">
              Repeat
            </label>
          </div>
          <div className="btn-group">
            <button type="button" className="btn">
              Edit <span className="visually-hidden">Repeat</span>
            </button>
            <button type="button" className="btn btn__danger">
              Delete <span className="visually-hidden">Repeat</span>
            </button>
          </div>
        </li>
      </ul>
    </div>
  );
}

 

 

 

3. public/index.html 파일 수정

기본으로 작성되있는 <title>React App</title>을 아래 코드로 복붙해줌~

<title>TodoMatic</title>

 

 

 

그럼 위와 같이 스타일이 적용이 안 된 날것 그대로 브라우저에 나옴~
