vite+ts+vue3+router4+Pinia+ElmPlus+axios+mock项目基本配置

1.vite+TS+Vue3

npm create  vite
Project name:... yourProjectName
Select a framework:>>Vue
Select a variant:>>Typescrit

2. 修改vite基本配置

配置 Vite {#configuring-vite} | Vite中文网 (vitejs.cn)

vite.config.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path';   // 编辑器提示 path 模块找不到，可以cnpm i @types/node --dev 即可

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],     // 默认配置

  resolve: {
    alias: {
      '@': resolve(__dirname, 'src')    // 配置别名；将 @ 指向'src'目录
    }
  },

  server: {
    port: 3000,       // 设置服务启动的端口号；如果端口已经被使用，Vite 会自动尝试下一个可用的端口
    open: true,       // 服务启动后自动打开浏览器
    proxy: {          // 代理
      '/api': {
        target: '真实接口服务地址',
        changeOrigin: true,
        rewrite: (path) => path.replace(/^\/api/, '')     // 注意代理地址的重写
      },
      // 可配置多个...
    }
  }
})

3.安装vue-router

cnpm install vue-router@4 --save

创建src/router/index.ts文件，使用路由懒加载，优化访问性能。

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

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    name: 'Home',
    component: () => import('@/views/home.vue') // 建议进行路由懒加载，优化访问性能
  },
  {
    path: '/about',
    name: 'About',
    component: () => import('@/views/about.vue')
  }
]

const router = createRouter({
  // history: createWebHistory(),    // 使用history模式
  history: createWebHashHistory(),	 // 使用hash模式
  routes
})

export default router

main.ts 里面引入router

import { createApp } from 'vue'
import App from './App.vue'
import router from './router/index'

createApp(App).use(router).mount('#app')

在App.vue 文件中使用router-view 组件，路由匹配到组件会通过router-view 组件进行渲染。

<template>
	<div id="nav">
    	<router-link to="/">Home</router-link> |
    	<router-link to="/about">About</router-link>
	</div>
	<router-view />
<template>

4.安装vuex 安装pinia

npm install vuex@next --save

创建src/store/index.ts文件。

import { createStore } from 'vuex'

const defaultState = {
  count: 0
}
const store = createStore({
  state () {
    return {
      count: 10
    }
  },
  mutations: {
    increment (state: typeof defaultState) {
      state.count++
    }
  }
})
export default store;

main.ts 里面引入vuex

import { createApp } from 'vue'
import App from './App.vue'
import router from './router/index'
import store from './store/index'

const app = createApp(App);

// 将store、router挂载到全局变量上, 方便使用
import { useStore } from "vuex";
import { useRoute } from "vue-router";
app.config.globalProperties.$store = useStore();
app.config.globalProperties.$router = useRoute();

app.use(router).use(store).mount('#app')

<template>
  <div>
    首页 {{count}}
    <p @click="handleSkip">点我</p>
  </div>
</template>

<script>
import { getCurrentInstance, computed, ref } from 'vue';
export default {
  name: 'Home',
  setup() {
    const { proxy } = getCurrentInstance();
    // 使用store
    const count = computed(() => proxy.$store.state.count);

    const handleSkip = () => {
      // 使用router
      proxy.$router.push('/about');
    }

    return {
      count: ref(count),
      handleSkip
    }
  }
}
</script>

pinia

yarn add pinia
# 或者使用 npm
npm install pinia

main.ts

import { createApp } from 'vue'
import './style.css'
import router from './router'
import { createPinia } from 'pinia'
import App from './App.vue'

createApp(App).use(router).use(createPinia()).mount('#app')

@/store/counter.ts

import { defineStore } from 'pinia'

export const useCounterStore = defineStore('counter', {
  state: () => ({ count: 0 }),
  getters: {
    double: (state) => state.count * 2,
  },
  actions: {
    increment() {
      this.count++
    },
  },
})

Home.vue

<template>
  <div><p>home</p>

  <button @click="increment">count:{{count}};double:{{double}}</button>

  </div>
</template>

<script setup lang="ts">
import { storeToRefs } from 'pinia';
import { useCounterStore } from '../store/counter';
const counter = useCounterStore()

const {count, double}  = storeToRefs(counter)//这样才是响应式的
const {increment } = counter
</script>

<style scoped></style>

5.安装 UI库

1.Element UI Plus

一个 Vue 3 UI 框架 | Element Plus

NPM

$ npm install element-plus --save

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'

const app = createApp(App)

app.use(ElementPlus)
app.mount('#app')

volar插件支持 获取对Element UI Plus 的提示 需要在tsconfig.json做如下设置

新增"types": ["element-plus/global"]

{
  "compilerOptions": {
    // ...
    "types": ["element-plus/global"]
  }
}

2.Ant Design Vue

Ant Design of Vue - Ant Design Vue (antdv.com)

$ npm install ant-design-vue@next --save

$ yarn add ant-design-vue@next

import { createApp } from 'vue';
import Antd from 'ant-design-vue';
import App from './App';
import 'ant-design-vue/dist/antd.css';

const app = createApp(App);

app.use(Antd).mount('#app');

3.Iview

npm install view-ui-plus --save

import { createApp } from 'vue'
import ViewUIPlus from 'view-ui-plus'
import App from './App.vue'
import router from './router'
import store from './store'
import 'view-ui-plus/dist/styles/viewuiplus.css'

const app = createApp(App)

app.use(store)
  .use(router)
  .use(ViewUIPlus)
  .mount('#app')

4.Vant 移动端

npm i vant -S

import Vant from 'vant'
import 'vant/lib/index.css';
createApp(App).use(Vant).$mount('#app)

6.安装axios

npm install axios --save

封装公共请求方法

新建工具类 src/utils/request.ts

import axios from 'axios'

interface ApiConfig {
  body: object;
  data: object
}

async function request(url: string, options: ApiConfig) {
  // 创建 axios 实例
  const service = axios.create({
    baseURL: "", // api base_url
    timeout: 6000 // 请求超时时间
  });
  // 请求拦截
  service.interceptors.request.use(config => {
    // 这里可设置请求头等信息
    if (options && options.body) {
      config.data = options.body;
    }
    return config;
  });
  // 返回拦截
  service.interceptors.response.use(response => {
    // 这里可进行返回数据的格式化等操作
    return response.data;
  });
  return service(url, options);
}
export default request;

使用方法

<script>
import request from "@/utils/request.ts"

export default {
  setup() {
    request('/api/getNewsList').then(res => {
        console.log(res);
        // to do...
    });
  }
}
</script>

7.安装mockjs

安装

mock 模拟数据我们选用 mockjs 插件，vite 中需要安装 vite-plugin-mock 插件。

npm install mockjs --save

npm install vite-plugin-mock --save-dev

vite.config.ts 中引用插件

import { viteMockServe } from 'vite-plugin-mock'

export default defineConfig({
  plugins: [
    vue(),
    viteMockServe({
      supportTs: true,
      mockPath: './src/mock'
    })],
})

使用mock

新建文件src/mock/index.ts，编写一下代码：

import { MockMethod } from 'vite-plugin-mock'
export default [
  {
    url: '/api/getNewsList',
    method: 'get',
    response: () => {
      return {
          code: 0,
          message: 'success',
          data: [
          	{
          		title: '标题111',
          		content: '内容1111'
          	},
          	{
          		title: '标题222',
          		content: '内容2222'
          	}
          ]
      }
    }
  },
  // more...
] as MockMethod[]

然后我们就可以在工程中进行 mock 数据的访问了，这里我们使用之前创建公共 api 请求方法 request。

<script>
import request from "@/utils/request.ts"

export default {
  setup() {
    request('/api/getNewsList').then(res => {
        console.log(res);
        // to do...
    });
  }
}
</script>
