想了解vite+vue3+element-plus项目搭建的方法步骤的相关内容吗,wkArtist在本文为您仔细讲解vite搭建vue3+ElementPlus的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:vite搭建vue3+ElementPlus,vite,vue3,element-plus,下面大家一起来学习吧。

使用vite搭建vue3项目

通过在终端中运行以下命令,可以使用 Vite 快速构建 Vue 项目。

$ npm init vite-app <project-name>
$ cd <project-name>
$ npm install
$ npm run dev

引入Element Plus

安装Element Plus:

npm install element-plus --save

main.js中完整引入 Element Plus:

import { createApp } from 'vue'
import ElementPlus from 'element-plus';
import 'element-plus/lib/theme-chalk/index.css';
import App from './App.vue';

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

引入SCSS

执行命令安装sass, npm i sass -D, 然后在vue文件的style标签下加入lang="scss"即可,这些与以前vue2都是一样的。

npm i sass -D

引入eslint

安装eslint

npm i eslint -D

使用eslint对本项目进行初始化

npx eslint --init

按照提示进行设置,这是我选择的设置

引入vue-router

安装Vue Router 4

npm install vue-router@4

在src目录下新建router文件夹,并在router下新建index.js进行路由配置

import * as VueRouter from 'vue-router'

const routes = [
  {
    path: '/',
    component: () => import('../page/Home.vue')
  }, {
    path: '/login',
    component: () => import('../page/Login.vue')
  }
]

export default VueRouter.createRouter({
  history: VueRouter.createWebHashHistory(),
  routes
})

在main.js下使用该中间件

import router from './router'
//...
app.use(router)

引入vuex

安装vuex

npm install vuex@next --save

在src下创建store路径,并在store下创建index.js

import { createStore } from 'vuex'

export default createStore({
  state () {
    return {
      username: ''
    }
  },
  mutations: {
    setUserName (state, payload) {
      state.username = payload
    }
  }
})

在main.js下使用store

import vuex from './store'
//...
app.use(vuex)

引入axios

对于网络请求,这里使用axios,首先安装axios

npm i axios

在src目录下创建api目录,并在api路径下创建axios.js,配置axios实例

// axios.js
import axios from 'axios'
// import config from '../../config'
import { useRouter } from 'vue-router'

export default function () {
  // 1. 发送请求的时候,如果有token,需要附带到请求头中
  const token = localStorage.getItem('token')
  let instance = axios

  if (token) {
    instance = axios.create({
      // baseURL: config.server,
      headers: {
        authorization: 'Bearer ' + token
      }
    })
  }

  const router = useRouter()
  instance.interceptors.response.use(
    (resp) => {
      // 2. 响应的时候,如果有token,保存token到本地(localstorage)
      if (resp.data.data.token) {
        localStorage.setItem('token', resp.data.data.token)
      }
      // 3. 响应的时候,如果响应的消息码是403(没有token,token失效),在本地删除token
      if (resp.data.code === 403) {
        localStorage.removeItem('token')
        localStorage.removeItem('username')
        router.push({ name: 'Login' })
      }
      return resp
    },
    (err) => {
      return Promise.reject(err)
    }
  )

  return instance
}

在api路径下创建index.js编写api

import request from './axios.js'
import config from '../../config'
export default {
  // 登录
  login (params) {
    return request().post(`${config.server}/login`, params)
  },
  // 获取用户列表
  getUserList (params) {
    return request().get(`${config.server}/user/list`, {
      params: params
    })
  },
  // 添加一个用户
  createUser (params) {
    return request().post(`${config.server}/user/`, params)
  },
  //...

接下来使用vue3的composition api进行组件的开发,这里列举一个User模块的开发:

<template>
  <div class="user-wrap">
      <el-button
        class="create-btn"
        type="success"
        size="small"
      @click="handleCreate">新增用户 +</el-button>
      <el-table
        :data="tableData"
        style="width: 100%">
        <el-table-column
            label="用户名"
            prop="username">
        </el-table-column>
        <el-table-column
            label="密码"
            prop="password">
        </el-table-column>
        <el-table-column
            align="right">
            <template #header>
                <el-input
                v-model="search"
                @blur="searchUser"
                size="mini"
                placeholder="输入用户名搜索"/>
            </template>
            <template #default="scope">
                <el-button
                size="mini"
                @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
                <el-button
                size="mini"
                type="danger"
                @click="handleDelete(scope.$index, scope.row)">删除</el-button>
            </template>
        </el-table-column>
    </el-table>
    <el-pagination
      :hide-on-single-page="hideOnSinglePage"
      class="page-wrap"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[10, 20, 30, 40]"
      :page-size="pageSize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="totalCount">
    </el-pagination>
    <el-dialog title="用户信息" v-model="dialogFormVisible">
        <el-form :model="form">
            <el-form-item label="用户名" :label-width="formLabelWidth">
                <el-input v-model="form.username" autocomplete="off"></el-input>
            </el-form-item>
            <el-form-item label="密码" :label-width="formLabelWidth">
                <el-input v-model="form.password" autocomplete="off"></el-input>
            </el-form-item>
        </el-form>
        <template #footer>
            <span class="dialog-footer">
                <el-button @click="dialogFormVisible = false">取 消</el-button>
                <el-button type="primary" @click="confirmUser">确 定</el-button>
            </span>
        </template>
    </el-dialog>
  </div>
</template>
