一、使用pnpm新建项目

可以使用npm 或yarn或pnpm来初始化Vite项目

pnpm create vite xxx(项目名称)
#选择vue
#选择js
cd xxx (进入项目目录)
#安装依赖
pnpm install  

二、使用vue router

1、安装

pnpm install vue-router@4

2、新建router/index.js

在src目录下创建router文件夹，在router文件夹内创建index.js文件。

import { createRouter,createWebHistory } from "vue-router";

const router = createRouter({
    history: createWebHistory(),
    routes: [
        // {
        //     path: '/HelloWorld',
        //     name: 'HelloWorld',
        //     component: () => import('@/components/HelloWorld.vue')
        // },
        {
            path: '/HelloWorld',
            name: 'HelloWorld',
            component: () => import('../components/HelloWorld.vue')
        },
    ]
})

export default router;

如果要使用上面那个路由的@/components/HelloWorld.vue写法，需要去vite.config.js文件配置如下，才能使用@写法

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  resolve: {
    alias: {
      '@': resolve(__dirname, 'src')
    }
  },
})

3、在main.js引入router

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

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

4、App.vue中添加

<template>
  <div id="app">
    <router-view />
  </div>
</template>

<style scoped>

</style>

三、集成pinia

1、安装依赖

pnpm i pinia

2、使用示例 store/user.js

import { loginAction } from '@/api/user'
import { defineStore } from 'pinia'

export const useUserStore = defineStore('user', {
  state: () => {
    return {
      username: '',
      avatar: ''
    }
  },

  actions: {
    update_username(username) {
      this.$patch((state) => {
        state.username = username
      })
    },

    login(data) {
      return new Promise((resolve, reject) => {
        loginAction(data).then(res => {
          if (res.code === 200) {
            resolve(null)
          } else {
            reject(res)
          }
        }).catch((error) => {
          reject(error)
        })
      })
    }
  }
})

3、挂载

在main.js中引入

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

const app = createApp(App)

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

四、集成element-plus

1、安装依赖

pnpm i element-plus

2、完整引入

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import locale from 'element-plus/lib/locale/lang/zh-cn'
import 'element-plus/dist/index.css'
import App from './App.vue'

const app = createApp(App)
// locale是为了汉化
app.use(ElementPlus, { locale })
app.mount('#app')

3、图标库配置

main.js中引入如下代码

import { createApp } from 'vue'
import App from './App.vue'
import * as ElementPlusIconsVue from '@element-plus/icons-vue'

const app = createApp(App)

for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
    app.component(key, component)
}

五、配置alias

一般使用@去引入某些文件，需要在vite.config.js中配置

import { defineConfig } from 'vite'
import path from 'path'

export default defineConfig({
  // ...
  define: {
    // path库报错修复
    'process.platform': null,
    'process.version': null
  },
  resolve: {
    alias: {
      '@': path.resolve(__dirname, 'src'),
    },
  },
})

六、

1、安装依赖

pnpm i axios

2、封装axios

import axios from 'axios'
import router from '@/router'
import { ElLoading, ElMessage, ElMessageBox } from 'element-plus'
import { getToken } from '@/utils/auth'
import { useUserStore } from '@/store/user'
let reqConfig
let loadingE

const service = axios.create()

// 请求拦截
service.interceptors.request.use(
  (request) => {
    // token setting
    request.headers['AUTHORIZE_TOKEN'] = getToken()
    /* download file*/
    if (request.isDownLoadFile) {
      request.responseType = 'blob'
    }
    /* upload file*/
    if (request.isUploadFile) {
      request.headers['Content-Type'] = 'multipart/form-data'
    }
    reqConfig = request
    if (request.bfLoading) {
      loadingE = ElLoading.service({
        lock: true,
        text: '数据载入中',
        background: 'rgba(0, 0, 0, 0.1)'
      })
    }
    /*
     *params会拼接到url上
     * */
    if (request.isParams) {
      request.params = request.data
      request.data = {}
    }
    return request
  },
  (err) => {
    Promise.reject(err)
  }
)
// 响应拦截
service.interceptors.response.use(
  (res) => {
    if (reqConfig.afHLoading && loadingE) {
      loadingE.close()
    }
    // 如果是下载文件直接返回
    if (reqConfig.isDownLoadFile) {
      return res
    }
    const { code } = res.data
    const successCode = '0,200,20000'
    if (successCode.includes(code)) {
      return res.data
    } else {
      //返回错误信息
      //注：如果没有return 则，会放回到请求方法中.then ,返回的res为 undefined
      return Promise.reject(res.data)
    }
  },
  (err) => {
    /*http错误处理*/
    if (loadingE) loadingE.close()
    ElMessage({
      message: err,
      type: 'error',
      duration: 2 * 1000
    })
    const errObj = {
      msg: err.toString(),
      reqUrl: reqConfig.baseURL + reqConfig.url,
      params: reqConfig.isParams ? reqConfig.params : reqConfig.data
    }
    return Promise.reject(JSON.stringify(errObj))
  }
)

export function axiosReq({
  url,
  data,
  method,
  isParams,
  bfLoading,
  afHLoading,
  isUploadFile,
  isDownLoadFile,
  baseURL
}) {
  return service({
    url: url,
    method: method ?? 'get',
    data: data ?? {},
    isParams: isParams ?? false,
    bfLoading: bfLoading ?? false,
    afHLoading: afHLoading ?? true,
    isUploadFile: isUploadFile ?? false,
    isDownLoadFile: isDownLoadFile ?? false,
    baseURL: baseURL ?? import.meta.env.VITE_APP_BASE_URL
  })
}

export default request

3、使用

import request from '@/utils/request'

export function loginAction(data) {
  return request({
    url: 'xxx',   // 请求地址
    data,
    method: 'post'
  })
}
