Vue3开发：简单实例说明路由VueRouter4的应用。
vue-router4保持了大部分API不变，我们只关注变化部分即可。一起来学习下吧。
安装
执行如下命令：
yarn add vue-router@4
使用
router.js
import { createRouter, createWebHistory } from "vue-router";
import Home from "./views/Home.vue";
const routes = [
{ path: "/", component: Home },
{ path: "/about", component: () => import("./views/About.vue") }
];
const router = createRouter({
history: createWebHistory(),
routes
});
export default router;
main.js
import { createApp } from "vue";
import App from "./App.vue";
import router from "./router";
const app = createApp(App);
app.use(router);
app.mount("#app");
App.vue
<h1>Hello App!</h1>
<p>
<router-link to="/">Go to Home</router-link>
<router-link to="/about">Go to About</router-link>
</p>
<router-view></router-view>
</template>
<script>
export default {};
</script>
一个小提示
如果你的 App.vue 模板只有 <router-view></router-view> 时， 可以吧 <router-view> 直接放入 index.html 中。
例如：
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<link rel="icon" href="/favicon.ico" rel="external nofollow" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Vite App</title>
</head>
<body>
<div id="app">
<router-view></router-view>
</div>
<script type="module" src="/src/main.js"></script>
</body>
</html>
之后 main.js 内移除 App.vue
main.js
import { createApp } from "vue";
// import App from "./App.vue";
import router from "./router";
// const app = createApp(App);
const app = createApp({});
app.use(router);
app.mount("#app");
