vue3使用vue-router构建SPA

标签：npm vue import vue3 axios router SPA pages

使用自动化构建工具vite搭建新项目

#某个目录下执行
npm create vite@latest

 按照提示初始化项目，并按照提示：

cd vite-project
npm install
npm run dev

生成目录结构如下：

  安装常用的类库

npm install vue-router --save 
npm install axios --save 
npm install bootstrap --save

定义路由

新建src/router/index.js

import { createRouter, createWebHistory } from "vue-router";
import Home from "../pages/Home.vue";

const router = createRouter({
    history: createWebHistory(),
    routes: [
        {
            path: "/",
            name: "home",
            component: Home,
        },
        {
            path: "/reg",
            name: "reg",
            component: () => import("../pages/Reg.vue"),
        },
        {
            path: "/login",
            name: "login",
            component: () => import("../pages/Login.vue"),
        },
    ],
});
export default router;

 修改main.js

import router from "./router";

createApp(App).use(router).mount("#app");

 使用vue-router组件

Vue Router 是 Vue.js 的官方路由。它与 Vue.js 核心深度集成，让用 Vue.js 构建单页应用变得轻而易举。

修改App.vue

<script setup>
import "bootstrap/dist/css/bootstrap.min.css";
import { RouterLink, RouterView } from "vue-router";
</script>

<template>
  <div class="container-fluid">
    <nav class="navbar navbar-expand-lg navbar-light bg-light rounded" aria-label="Eleventh navbar example">
      <div class="container-fluid">
        <a class="navbar-brand" href="#">LOGO</a>

        <div class="collapse navbar-collapse">
          <ul class="navbar-nav me-auto mb-2 mb-lg-0">
            <li class="nav-item">
              <RouterLink to="/" class="nav-link active">Home</RouterLink>
            </li>
          </ul>

          <ul class="navbar-nav ms-auto mb-2">
            <li class="nav-item">
              <RouterLink to="/reg" class="nav-link ms-3">Register</RouterLink>
            </li>
            <li class="nav-item">
              <RouterLink to="/login" class="nav-link ms-3">Login</RouterLink>
            </li>
          </ul>
        </div>
      </div>
    </nav>
    <RouterView />
  </div>
</template>
<style>
a {

 src/pages/Home.vue
