over-dismissableLayer

DismissableLayer는 모달 컴포넌트의 닫히는 동작을 위해 만들어진 레이어 컴포넌트 입니다 모달을 만들 때 마다 처리에 대한 반복되는 부분이 발생하기때문에 관심사의 분리를 위해 구현하게 됐습니다 모달의 content가 되는 부분을 감싸서 dismissableLayer가 아닌 부분을 클릭하거나, 포커스를 내보내거나, escape 키를 눌렀을 경우 onDismiss 함수를 실행시켜 모달을 닫는 방법으로 사용할 수 있습니다

Usage

import * as React from 'react';
import { Poly } from '@over-ui/core';
import { DismissableLayer } from '@over-ui/dismissableLayer';
