Vue3+Element Plus+TS开发企业管理后台(二)

使用vite初始化项目

确保你的开发环境中已经安装了Node.js，而且有npm，yarn等包管理工具，然后可以按照vite官方提供的方式初始化项目：

bash 复制代码

yarn create vite

跟随提示选择即可：

或者可以直接克隆下面的仓库

安装项目依赖

bash 复制代码

➜  vat yarn add vue-router element-plus echarts nprogress

新增router、layouts目录

在src目录下新增router用于配制项目路由，layouts用于存放项目的布局组建。

在layouts中新增login.vue文件用来处理登录页面的样式和登录、注册校验等逻辑。

html 复制代码

<template>
  <div class="login-container">
    <div class="login-form" v-if="mode === 'login'">
      <h1>Hello!</h1>
      <h2>欢迎来到 Vue Admin TS!</h2>

在router中新增index.ts管理项目路由

bash 复制代码

import { createRouter, createWebHistory } from "vue-router";
import LoginLayout from "../layouts/login.vue";
import NProgress from "nprogress";
import "nprogress/nprogress.css";

const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: "/login",
      name: "Login",
      component: LoginLayout,
    },
  ],
});

NProgress.configure({
  easing: "ease",
  speed: 500,
  trickleSpeed: 200,
  showSpinner: false,
});

export default router;

现在我们启动项目访问http://localhost:5174/login，你本地的端口可能不是5174，按你自己的实际情况访问。

这样登录注册页面就完成了，并且在移动端浏览器中访问也有不错的样式。

OK，下一篇做一下首页的页面布局。
