我正在使用Webpack3.7.1和React 15.6.1,并尝试动态加载不同的组件

我想做什么
  • 从代码拆分时创建的不同块Web包异步加载组件
我所做的
  • 使用getComponent()import()生成块
  • 正确配置webpack.config文件,以便创建块(代码拆分)
问题
  • 访问路由时,生成块,但未正确加载块
  • getComponent()似乎不起作用
我的Webpack.config文件 My index.js文件(我的react应用程序的根目录)
从“React”导入React;
从“react dom”导入react dom;
从“react redux”导入{Provider};
从“redux”导入{createStore,applyMiddleware};
从“react router dom”导入{BrowserRouter,Route,Switch};
从“redux承诺”导入承诺;
从“/reducers”导入减速机;
从“/containers/AppInit”导入AppInit;
从“/containers/modals/register\u prof\u exploration\u model”导入ProfRegisteringModel;
const createStoreWithMiddleware=applyMiddleware(promise)(createStore);
函数错误加载(err){
控制台错误(“动态页面加载失败”,错误);
}
功能加载路径(cb){
返回module=>cb(null,module.default);
}
console.log(“testst”);
ReactDOM.render(
{
进口(
“/components/registing/registing_landing_page.js”
)
.然后(装载路线(cb))
.捕获(错误加载);
}}
/>
{
进口(
“/components/registing/registing_landing_page.js”
)
.然后(装载路线(cb))
.捕获(错误加载);
}}
/>
{
导入(“./containers/registing/signing_in.js”)
.然后(装载路线(cb))
.捕获(错误加载);
}}
/>
{
导入(“./components/team_pres.js”)
.然后(装载路线(cb))
.捕获(错误加载);
}}
/>
{
导入(“./containers/app_container.js”)
.然后(装载路线(cb))
.捕获(错误加载);
}}
/>
,
document.querySelector(“.root”)
);
这个index.js文件加载正确,因为我可以看到控制台中出现的console.log(“test”)

访问任何路由时,没有一个组件正确加载。

非常感谢你的帮助 更新
一定要有Babel polyfill!!我就是这样解决的

您的webpack.config文件似乎很好。我所做的工作是在中创建异步组件

import React,{Component}来自“React”;
导出默认函数asyncComponent(导入组件){
类AsyncComponent扩展组件{
建造师(道具){
超级(道具);
此.state={
组件:空
};
}
异步组件didmount(){
const{default:component}=wait importComponent();
这是我的国家({
组件:组件
});
}
render(){
const C=this.state.component;
返回C?:空;
}
}
返回异步组件;

}
谢谢您的回答!你确定你能写render:props=>我刚做的组件={RegisterPage},效果很好,谢谢!!我的主要问题是因为我错过了babel polyfill!!
