react spinners for loading layer 본문
반응형
axios data fetch시에 loader를 표시해 보고자 찾아 봤다.
세상엔 좋은 사람들이 많다.ㅎㅎ
https://github.com/davidhu2000/react-spinners
Example을 보고 따라서 만들어 봤다.
App()내어서 사용할 state를 선언하고, axios interceptor를 구현했다. axios실행시 동작한다.
const [loading, setLoading] = useState(false);
useEffect(() => {
axios.interceptors.request.use((config) => {
console.log('loading layer open');
setLoading(true);
return config;
}, (error) => {
console.log('loading layer close caused by request error');
setLoading(false);
return Promise.reject(error);
});
axios.interceptors.response.use((config) => {
console.log('loading layer close');
setLoading(false);
return config;
}, (error) => {
console.log('loading layer close caused by response error');
setLoading(false);
return Promise.reject(error);
});
return () => {
}
}, []);
Loader 콤포넌트를 만들고 ( @emotion/css, @emotion/react 설치 필요 )
import { css } from "@emotion/react";
import ClipLoader from "react-spinners/ClipLoader";
const override = css`
display: block;
margin: 0 auto;
border-color: rgba(255,255,255,0.7);
border-width: 10px;
`;
export default function Loader(props) {
return (
<>
<div className={'axios-loading'} style={{display:props.loading===true?'block':'none'}}>
<div className={'axios-loading-indicator'}>
<ClipLoader color={props.color} loading={props.loading} css={override} size={150} />
</div>
</div>
</>
)
}
css추가
.axios-loading {
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: 999;
overflow: auto;
display: block;
position: fixed !important;
background-color: rgba(0, 0, 0, 0.1);
}
.axios-loading-indicator {
top: 45%;
left: calc(50% - 75px);
position: fixed;
}
App render에 컴포넌트 부착(?)
<Loader loading={loading} color={color} onClick={setLoading}/>
bootstrap 5에는 Spinner가 자체적으로 있다. 물론 react-bootstrap v2에도 있다.
import React, {JSX} from 'react';
import {Spinner} from "react-bootstrap";
interface LoaderProps {
loading: boolean
}
const Loader = (props: LoaderProps): JSX.Element => {
return (
<div
className={`${props.loading === false && 'd-none'} d-flex align-items-center justify-content-center top-0 vw-100 vh-100 mw-100 mh-100 full position-absolute bg-black bg-opacity-50`}>
<Spinner variant={"light"} animation={"border"} as={"span"}/>
</div>
);
}
export default Loader;
state로 관리하면 된다.
