1.下载管理node版本的工具nvm(Node Version Manager)
2.安装node(vue工程的环境管理工具):nvm install 16.13.0
3.安装vue工程的脚手架:npm install -g @vue/cli
4.在合适的路径下创建工程:vue create back-manage
5.项目最终打包:npm run build
,生成dist文件夹就是打包文件。
1.安装:npm install element-plus --save
和图标安装:npm install @element-plus/icons-vue
2.全局引入:
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')
3.按需引入:
首先安装插件:npm install -D unplugin-vue-components unplugin-auto-import
npm install babel-plugin-component --save-dev
然后修改工程的babel.config.js文件
module.exports = {
presets: [
'@vue/cli-plugin-babel/preset',
["@babel/preset-env",{"modules":false}]
],
"plugins": [
[
"component",
{
"libraryName": "element-ui",
"styleLibraryName": "theme-chalk"
}
]
]
}
最后在main.js里面按需引入
import { createApp } from 'vue'
import { ElButton, ElRow } from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'
const app = createApp(App)
app.use(ElButton)//按需引入
app.use(ElRow)
app.mount('#app')
因为之后使用element组件,但element很多代码都用到了ts(typescripte)语法,因此需要安装相关依赖并配置:npm install @types/element-ui --save-dev
搞了好久没成功,干脆在最初创建项目时手动选择,然后选择到typescript。
1.安装:npm install vue-router
2.在工程的src目录下新建router/index.js作为路由配置文件
3.在工程的src目录下新建views目录作为视图组件,然后在里面创建自己的组件文件(Home.vue和User.vue)
4.在工程的vue.config.js中关闭eslint代码风格规范校验:lintOnSave:false
5.开始在router/index.js里面将路由和组件进行映射,并创建router示例导出
import { createRouter, createWebHistory } from 'vue-router';
import Home from '../views/Home.vue';
import User from '../views/User.vue';
const routes=[
{path:"/home",component:Home},//1.将路由和组件进行关系映射
{path:"/user",component:User},
];
const router = createRouter({
history: createWebHistory(),//2.使用vue-router创建router实例
routes: routes,//缩写:routes
});
export default router;//3.导出router示例
6.在main.js中将上面导出的router挂载到根节点上。
import { createApp } from 'vue'
import App from './App.vue'
import router from './router' // 导入你的路由配置文件
const app = createApp(App)
app.use(router) // 使用 Vue Router 插件
app.mount('#app')
7.在App.vue里面写路由出口,将路由匹配到的组件渲染在此位置:
8.嵌套路由:
创建main组件,然后在index.js里面进行路由和组件的映射:
const routes=[
{
path:"/",//主路由
component:Main,
children:[
{path:"/home",component:Home},//子路由
{path:"/user",component:User},
]
}
];
而组件的渲染位置除了主路由在App.vue里面渲染,子组件也在主组件的vue里面渲染,所以要在主组件里面添加
1.使用element组件搭建Main.vue的主要框架(Container 布局容器,Menu 菜单,Icon 图标)
icon用到了element的icon,需要下载npm install @element-plus/icons-vue
并在main.ts里面导入使用
import { createApp } from 'vue'
import App from './App.vue'
import './registerServiceWorker'
import router from './router'
import store from './store'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
// createApp(App).use(store).use(ElementPlus).use(router).mount('#app')
import * as ElementPlusIconsVue from '@element-plus/icons-vue'
const app = createApp(App)
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
app.component(key, component)
}
app.use(store).use(ElementPlus).use(router).mount('#app')
2.使用到了less的css解析器,所以要下载npm i less less-loader
,然后在style里面加上
我的CommentLeft.vue文件如下

<el-row class="tac">

const noChildren = computed(() => menuData.filter(item => !item.children));
const hasChildren = computed(() => menuData.filter(item => item.children));
const router = useRouter();
const clickMenu = (item) => {
if (router.currentRoute.value.path !== item.path && !(router.currentRoute.value.path === "/home" && item.path === "/")) {
router.push(item.path);
}
};
</script>
<style lang="less" scope>

</style>
1.使用到了icon和Dropdown 下拉菜单。
2.使用到了Vuex进行状态管理模式,就是在一个父组件下面有的好多子组件,然后这些子组件共享某些数据,下载:npm install vuex@next --save
在我这里面现在left和header这两个子组件共享了isCollapse这个值。
