React@16.x（40）路由v5.x（5）常见应用场景（2）- 实现类似 vue 的路由模式

1，vue-router

vue 的路由配置文件，

// src/router/index.ts
const routes = [{path: "/news",children: [{ path: "", component: NewsView },{ path: "detail", component: NewsDetail },{ path: "search", component: NewsSearch },],},{path: "/goods",component: GoodsView,children: [{ path: "detail", component: GoodsDetail },{ path: "search", component: GoodsSearch },],},{ path: "/", component: HomeView },
];

在 App.vue 中使用 RouterView 即可渲染匹配到的路由：

<template><RouterView></RouterView>
</template>

另外，注意 news 和 goods 路由的区别：

• news 相关的3个路由页面是相互独立的，只是逻辑上有关系。
• goods 路由的写法，需要在 GoodsView 组件内也使用 RouterView 才能访问到路由 goods/detail 和 goods/search 对应的页面。

<template><div>goods主页面</div><RouterView></RouterView>
</template>

2，React 模拟实现

使用和 vue 相同的配置文件，routeConfig.js

App.jsx

import { BrowserRouter as Router, Switch, Link } from "react-router-dom";
import RootRoute from "./RootRoute";export default function App() {return (<Router><Link to="/">首页</Link><Link to="/news">新闻页</Link><Link to="/goods">商品页</Link><Switch><RootRoute></RootRoute></Switch></Router>);
}

关键实现：RootRoute.js

import React from "react";
import { Route } from "react-router-dom";
import routeConfig from "./routeConfig";export default function RootRoute() {return getRoutes(routeConfig, "");
}function getRoutes(routes, basePath) {if (!Array.isArray(routes)) {return null;}return routes.map((route) => {const { path, component: Component, children, ...rest } = route;const newPath = `${basePath}${path}`;// 适配 news 路由的方式if (Component) {return (<Routekey={newPath}path={newPath}exact={["", "/"].includes(path)}{...rest}render={(values) => {return <Component {...values}>{getRoutes(children, newPath)}</Component>;}}></Route>);} else {return getRoutes(children, newPath);}});
}

News.jsx

export default function News() {return (<div><div>News页面</div><Link to="/news/detail">详情</Link><Link to="/news/search">查询</Link></div>);
}

Goods.jsx，其中 props.children 是 RootRoute.js 遍历子路由渲染出对应的 <Route> 组件。

export default function Goods(props) {return (<div><div>Goods页面</div><Link to="/goods/detail">goods详情</Link><Link to="/goods/search">goods查询</Link><div>{props.children}</div></div>);
}

效果：
