二. 第三方库集成 
2.1. vue.config.js配置 
vue.config.js有三种配置方式:
- 方式一:直接通过CLI提供给我们的选项来配置: - 比如publicPath:配置应用程序部署的子目录(默认是 /,相当于部署在https://www.my-app.com/);
- 比如outputDir:修改输出的文件夹;
 
- 比如publicPath:配置应用程序部署的子目录(默认是 
- 方式二:通过configureWebpack修改webpack的配置: - 可以是一个对象,直接会被合并;
- 可以是一个函数,会接收一个config,可以通过config来修改配置;
 
- 方式三:通过chainWebpack修改webpack的配置: - 是一个函数,会接收一个基于 webpack-chain 的config对象,可以对配置进行修改;
 
js
const path = require('path')
module.exports = {
  outputDir: './build',
  // configureWebpack: {
  //   resolve: {
  //     alias: {
  //       views: '@/views'
  //     }
  //   }
  // }
  // configureWebpack: (config) => {
  //   config.resolve.alias = {
  //     '@': path.resolve(__dirname, 'src'),
  //     views: '@/views'
  //   }
  // },
  chainWebpack: (config) => {
    config.resolve.alias.set('@', path.resolve(__dirname, 'src')).set('views', '@/views')
  }
}2.2. vue-router集成 
安装vue-router的最新版本:
shell
npm install vue-router@next创建router对象:
ts
import { createRouter, createWebHashHistory } from 'vue-router'
import { RouteRecordRaw } from 'vue-router'
const routes: RouteRecordRaw[] = [
  {
    path: '/',
    redirect: '/main'
  },
  {
    path: '/main',
    component: () => import('../views/main/main.vue')
  },
  {
    path: '/login',
    component: () => import('../views/login/login.vue')
  }
]
const router = createRouter({
  routes,
  history: createWebHashHistory()
})
export default router安装router:
ts
import router from './router'
createApp(App).use(router).mount('#app')在App.vue中配置跳转:
html
<template>
  <div id="app">
    <router-link to="/login">登录</router-link>
    <router-link to="/main">首页</router-link>
    <router-view></router-view>
  </div>
</template>2.3. vuex集成 
安装vuex:
shell
npm install vuex@next创建store对象:
ts
import { createStore } from 'vuex'
const store = createStore({
  state() {
    return {
      name: 'coderwhy'
    }
  }
})
export default store安装store:
ts
createApp(App).use(router).use(store).mount('#app')在App.vue中使用:
html
<h2>{{ $store.state.name }}</h2>2.4. element-plus集成 
Element Plus,一套为开发者、设计师和产品经理准备的基于 Vue 3.0 的桌面端组件库:
- 相信很多同学在Vue2中都使用过element-ui,而element-plus正是element-ui针对于vue3开发的一个UI组件库;
- 它的使用方式和很多其他的组件库是一样的,所以学会element-plus,其他类似于ant-design-vue、NaiveUI、VantUI都是差不多的;
安装element-plus
shell
npm install element-plus2.4.1. 全局引入 
一种引入element-plus的方式是全局引入,代表的含义是所有的组件和插件都会被自动注册:
js
import ElementPlus from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'
import router from './router'
import store from './store'
createApp(App).use(router).use(store).use(ElementPlus).mount('#app')2.4.2. 局部引入 
也就是在开发中用到某个组件对某个组件进行引入:
vue
<template>
  <div id="app">
    <router-link to="/login">登录</router-link>
    <router-link to="/main">首页</router-link>
    <router-view></router-view>
    <h2>{{ $store.state.name }}</h2>
    <el-button>默认按钮</el-button>
    <el-button type="primary">主要按钮</el-button>
    <el-button type="success">成功按钮</el-button>
    <el-button type="info">信息按钮</el-button>
    <el-button type="warning">警告按钮</el-button>
    <el-button type="danger">危险按钮</el-button>
  </div>
</template>
<script lang="ts">
import { defineComponent } from 'vue'
import { ElButton } from 'element-plus'
export default defineComponent({
  name: 'App',
  components: {
    ElButton
  }
})
</script>
<style lang="less">
</style>但是我们会发现是没有对应的样式的,引入样式有两种方式:
- 全局引用样式(像之前做的那样);
- 局部引用样式(通过babel的插件);
1.安装babel的插件:
shell
npm install babel-plugin-import -D2.配置babel.config.js
js
module.exports = {
  plugins: [
    [
      'import',
      {
        libraryName: 'element-plus',
        customStyleName: (name) => {
          return `element-plus/lib/theme-chalk/${name}.css`
        }
      }
    ]
  ],
  presets: ['@vue/cli-plugin-babel/preset']
}但是这里依然有个弊端:
- 这些组件我们在多个页面或者组件中使用的时候,都需要导入并且在components中进行注册;
- 所以我们可以将它们在全局注册一次;
ts
import {
  ElButton,
  ElTable,
  ElAlert,
  ElAside,
  ElAutocomplete,
  ElAvatar,
  ElBacktop,
  ElBadge,
} from 'element-plus'
const app = createApp(App)
const components = [
  ElButton,
  ElTable,
  ElAlert,
  ElAside,
  ElAutocomplete,
  ElAvatar,
  ElBacktop,
  ElBadge
]
for (const cpn of components) {
  app.component(cpn.name, cpn)
}2.5. axios集成 
安装axios:
shell
npm install axios封装axios:
ts
import axios, { AxiosInstance, AxiosRequestConfig, AxiosResponse } from 'axios'
import { Result } from './types'
import { useUserStore } from '/@/store/modules/user'
class HYRequest {
  private instance: AxiosInstance
  private readonly options: AxiosRequestConfig
  constructor(options: AxiosRequestConfig) {
    this.options = options
    this.instance = axios.create(options)
    this.instance.interceptors.request.use(
      (config) => {
        const token = useUserStore().getToken
        if (token) {
          config.headers.Authorization = `Bearer ${token}`
        }
        return config
      },
      (err) => {
        return err
      }
    )
    this.instance.interceptors.response.use(
      (res) => {
        // 拦截响应的数据
        if (res.data.code === 0) {
          return res.data.data
        }
        return res.data
      },
      (err) => {
        return err
      }
    )
  }
  request<T = any>(config: AxiosRequestConfig): Promise<T> {
    return new Promise((resolve, reject) => {
      this.instance
        .request<any, AxiosResponse<Result<T>>>(config)
        .then((res) => {
          resolve((res as unknown) as Promise<T>)
        })
        .catch((err) => {
          reject(err)
        })
    })
  }
  get<T = any>(config: AxiosRequestConfig): Promise<T> {
    return this.request({ ...config, method: 'GET' })
  }
  post<T = any>(config: AxiosRequestConfig): Promise<T> {
    return this.request({ ...config, method: 'POST' })
  }
  patch<T = any>(config: AxiosRequestConfig): Promise<T> {
    return this.request({ ...config, method: 'PATCH' })
  }
  delete<T = any>(config: AxiosRequestConfig): Promise<T> {
    return this.request({ ...config, method: 'DELETE' })
  }
}
