React实现一个通用骨架屏组件示例

npm install obiusm-react-components

import { Skeleton } from 'obiusm-react-components';

    <div className="wrapper">
      <div className="content1"></div>

      <div className="content2"></div>

    </div>
  </Skeleton>

function Skeleton(props: Props) {
  if (!props) {
    return <div />;
  }
  if (props.isVisible) {
    return createModal(props.children, props.depth || 4, 0);
  } else {
    return props.children ? props.children : <div />;
  }
}

  if (
    depth === current ||
    (child && child.props && child.props['data-skeleton-ignore'])
