vue3+TS+Pinia+Vite项目实战之一

---

一、创建项目

1.1 使用脚手架创建项目

npm init vue@latest

1.2 初始化项目

App.vue

<template>
  <RouterView />
</template>

<script setup lang="ts"></script>

<style scoped></style>

删除多余不要的组件

创建路由
src/router/index.ts

import { createRouter, createWebHistory } from 'vue-router'

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/login',
      name: 'Login',
      component: () => import('../views/LoginView.vue')
    }
  ]
})

export default router

在src/views/LoginView.vue

<template>
  <div>Logindiv>
template>

<script setup lang="ts">script>

<style lang="scss" scoped>style>

引入element-plus 可去官网查看如何引入
安装normalize.css

npm install normalize.css

二、登录页面的开发

安装sass

npm install sass

登录页的静态页面

<template>
  <div class="login-container">
    <h2>登录h2>
    <el-form ref="ruleFormRef" :model="formData" status-icon :rules="rules">
      <el-form-item prop="userName">
        <el-input v-model="formData.userName" placeholder="userName" />
      el-form-item>

      <el-form-item prop="password">
        <el-input v-model="formData.password" placeholder="password" type="password" />
      el-form-item>

      <el-form-item>
        <el-button type="primary" @click="submitForm(ruleFormRef)">登录el-button>
      el-form-item>
    el-form>
  div>
template>

<script setup lang="ts">
import { ref, reactive } from 'vue'
import type { FormInstance, FormRules } from 'element-plus'
const ruleFormRef = ref<FormInstance>()
const formData = reactive({
  userName: '',
  password: ''
})

const rules = reactive<FormRules>({
  userName: [{ required: true, message: '请输入用户名', trigger: 'blur' }],
  password: [{ required: true, message: '请输入密码', trigger: 'blur' }]
})

const submitForm = (formEl: FormInstance | undefined) => {
  if (!formEl) return
  formEl.validate((valid) => {
    if (valid) {
      console.log('submit!')
    } else {
      console.log('error submit!')
      return false
    }
  })
}
script>

<style lang="scss" scoped>
.login-container {
  // 要加上100%
  height: 100%;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  .el-form {
    width: 300px;
    .el-button {
      width: 100%;
    }
  }
}
style>

三、使用vite-plugin-mock模拟后台接口返回数据

安装方法

npm i  mockjs -S
npm i vite-plugin-mock -D

配置vite-plugin-mock

开始使用mock使其返回数据

四、前端调用后端接口使用axios

安装axios

npm i axios -S

简单封装一下axios




在mock中添加逻辑返回真实的数据
/mock/user.ts

import type { MockMethod } from 'vite-plugin-mock'

// 模拟用户账户
const tokens = {
  admin: 'admin-token',
  editor: 'editor-token'
}

export default [
    {
      // 请求到这里的路径我来接收处理
      url: '/user/login',
      method: 'post',
      // 响应回去请求的数据
      // {body} 解构出来body的数据
      response({body}){
        const userName = body.userName
        const token = tokens[userName]
        if(token){
          return {
            code: 200,
            data: token
          }
        }else{
          return {
            code: 400,
            message: '账号或密码不正确'
          }
        }
      }
    }
] as MockMethod[]

在axios响应拦截器中处理接口错误在页面提示

登录成功跳转到首页

添加首页路由

在src/views/HomeView.vue

五、首页layout

调整路由


调整layout的样式

现在可以在element-plus中去复制一个菜单贴过来了。
LayoutSidebar.vue

<template>
  <div class="container">
    <el-menu
      background-color="#545c64"
      active-text-color="#ffd04b"
      text-color="#fff"
      default-active="1"
    >
      <el-menu-item index="1">首页el-menu-item>
      <el-menu-item index="2">菜单2el-menu-item>
    el-menu>
  div>
template>

<script setup lang="ts">script>

<style lang="scss" scoped>
.container {
  width: 200px;
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  :deep(.el-menu) {
    height: 100%;
  }
}
style>

六、动态菜单

现在的菜单是写死的，我们需要根据路由动态生成菜单。
将路由导出来使其在别的文件中能够使用。
调整src/router/index.ts

import { createRouter, createWebHistory } from 'vue-router'

export const constantRoutes = [
  {
    path: '/login',
    name: 'Login',
    component: () => import('../views/LoginView.vue')
  },
  {
    path: '/',
    name: 'Home',
    component: () => import('../components/LayoutIndex.vue'),
    redirect: '/dashboard',
    children: [
      {
        path: 'dashboard', 
        component: () => import('@/views/DashboardView.vue')
      }
      
    ]
  }
]

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: constantRoutes
})

export default router

调整 src/components/LasyoutSidebar.vue




当只有一个子路由，我们只显示子路由的调整



点击菜单并没有跳转，继续调整…

总结动态菜单：就是通过递归组件将路由中数据展示在动态菜单上。

七、设置需要登录才能访问某些页面

登录成功将token存起来

设置前置路由守卫，没token你就去/login页面吧

退出登录
LayoutNavbar.vue

<template>
  <div class="layout-navbar">
    <el-button @click="handleLogout" style="margin-left: auto" type="primary">退出登录el-button>
  div>
template>

<script setup lang="ts">
import { useRouter } from 'vue-router'
const router = useRouter()
function handleLogout() {
  localStorage.removeItem('token')
  router.push('/login')
}
script>

<style lang="scss" scoped>
.layout-navbar {
  height: 50px;
  border-bottom: 1px solid #ccc;
  box-sizing: border-box;
  padding: 0 16px;
  display: flex;
  align-items: center;
}
style>
