16.13.0中的响应延迟加载问题

Question

import React, { Component,lazy,Suspense} from 'react';
import LayoutComponent from './components/layout/Layout'
import BurgerBuilderContainer from './Containers/BurgerBuilder/BurgerBuilder'
import CheckoutContainer from './Containers/CheckOut/Checkout'
import { Route, Switch,withRouter } from 'react-router-dom'
 const OrdersContainer = lazy(()=> {
  return import('./Containers/Orders/Orders')
 })

render(){
return (
  <div>
    <Suspense fallback={<div>Loading...</div>}>
    <LayoutComponent>
      <Switch>
      <Route path="/Logout" component={LogoutContainer}></Route>
      <Route path="/Auth" component={AuthContainer}></Route>
        <Route path="/Orders" component={OrdersContainer}></Route>
        <Route path="/checkout" component={CheckoutContainer}></Route>
        <Route path="/" component={BurgerBuilderContainer}></Route>
      </Switch>
    </LayoutComponent>
    </Suspense>
  </div>
);
}

在使用延迟加载应用程序之前，错误的延迟加载在导入时显示错误，应用程序运行正常。

Answer 1

您可以尝试使用

const OrdersContainer= React.lazy(() => import('./Containers/Orders/Orders'));

如果错误仍然存​​在，请尝试

const OrdersContainer= React.lazy(() => require('./Containers/Orders/Orders'));

如果仍然继续

React.lazy(() => import("./Containers/Orders/Orders").then(x => x.default))

最后

导入@babel/plugin-syntax-dynamic-import
