react打包脚本和example, 这里的版本请忽略

import notificationDOM from './notification';
import './icons';

let notification;
const notice = (type, content, duration = 2000, onClose) => {
    if (!notification) notification = notificationDOM;
    return notification.addNotice({type, content, duration, onClose});
};
