import React from 'react';
class AdminPageLoader extends React.PureComponent {
    constructor(props) {
         super(props);    
         this.state = {      AdminPage: null,    }  
  }  

  componentDidMount() {    
    import('./AdminPage').then(module => {      
      this.setState({ AdminPage: module.default });    
    }); 
   }  
   
   render() {   
     const { AdminPage } = this.state;
     return AdminPage ? <AdminPage {...this.props} /> : <div>Loading...</div>;
