vue可以用vite打包吗
vite+vue3+element-plus项目搭建的方法步骤使用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
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')
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
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
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)
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)
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(`${config.server}/user/`, params)
},
//...
接下来使用vue3的composition api进行组件的开发，这里列举一个User模块的开发:
<template>
<li class="user-wrap">
<el-button
class="create-btn"
type="success"
size="small"
@click="handleCreate">新增用户 +</el-button>
<el-table
:data="tableData"
style="width: 100%">
<el-table-column
label="用户名"
prop="username">
</el-table-column>
<el-table-column
label="密码"
prop="password">
</el-table-column>
<el-table-column
align="right">
<template #header>
<el-input
v-model="search"
@blur="searchUser"
size="mini"
placeholder="输入用户名搜索"/>
</template>
<template #default="scope">
<el-button
size="mini"
@click="handleEdit(scope.$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>
</li>
</template>
