使用 dva 如何配置异步加载路由组件

-----------------------------------------------------

普通方式 文件目录：src/route.js

import React from 'react' import { Router, Route, Switch } from 'dva/router' import IndexPage from './routes/IndexPage'; import Category from './routes/Category'; function RouterConfig({ history, app }) { return ( <Router history={history}> <Switch> <Route path="/" exact component={IndexPage} /> <Route path="/category" exact component={Category} /> </Switch> </Router> ) } export default RouterConfig 

1. 使用异步路由加载组件 在文件头部引入

import dynamic from 'dva/dynamic' 

而后删除如下代码

import IndexPage from './routes/IndexPage'; import Category from './routes/Category'; 

在RouteConfig函数中添加如下代码便可

const CompontentPage = dynamic({ component: () => import('./routes/CompontentPage') }) const CompontentPage1 = dynamic({ component: () => import('./routes/CompontentPage1') }) 

完整实例

import React from 'react' import { Router, Route, Switch } from 'dva/router' import dynamic from 'dva/dynamic' function RouterConfig({ history, app }) { const IndexPage = dynamic({ app, component: () => import('./routes/IndexPage') }) const Category = dynamic({ app, component: () => import('./routes/Category') }) return ( <Router history={history}> <Switch> <Route path="/" exact component={IndexPage} /> <Route path="/category" exact component={Category} /> </Switch> </Router> ) } export default RouterConfig 

很简单把~~
