Vue3 + TS + Antd + Pinia 从零搭建后台系统(四) ant-design-vue Layout布局，导航栏，标签页

书接上回

本篇主要介绍： Layout布局，导航栏，标签页

继续填充

按需引入组件

使用unplugin-vue-components插件完成ant-design-vue组件的按需加载。
前文中已处理过，详情见前文

此处还需在tsconfig.json同级添加文件 components.d.ts。
tsconfig.json文件配置如下：

{
  "compilerOptions": {
    "target": "es2019",
    "module": "esnext",
    "strict": true,
    "jsx": "preserve",
    "allowJs": true,
    "importHelpers": true,
    "moduleResolution": "node",
    "outDir": "temp",
    "resolveJsonModule": true,
    "experimentalDecorators": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "paths": {
      "@/*": ["src/*"]
    },
    "types": [
      "@intlify/unplugin-vue-i18n/types",

      "element-plus/global",
      "@types/qrcode",

    ],
    "baseUrl": "./",

  },
  "include": [

    "src/plugin/index.js"
  ],
  "exclude": ["dist", "node_modules"]
}

Layout布局，导航栏，标签页

这里统一写在layout文件夹下面
此处用到的图标为iconfont图标库中的图标，可替换为ant-design-vue中的图标

index.vue文件：


  <Layout style="height: 100%; width: 100%">
    <!-- 左侧菜单栏 -->
    <Layout-sider
      :class="collapsed ? 'side-logo' : 'side-title'"
      v-model:collapsed="collapsed"
      :trigger="null"
      collapsible
    >
      <div style="height: 50px">
        <img class="logo-style" src="../../assets/images/logo.png" />
        <div v-if="!collapsed" class="title-style">管理平台</div>

css样式

style文件夹下，创建index.css 、antd.css、 layout.css

index.css

@import './antd.css';

a {
  font-weight: 500;
  color: #646cff;
  text-decoration: inherit;
}
a:hover {
  color: #535bf2;
}

body {
  margin: 0;
  display: flex;
  place-items: center;
  min-width: 320px;
  min-height: 100vh;
}

h1 {
  font-size: 3.2em;
  line-height: 1.1;
}

.card {
  padding: 2em;
}

#app {
  margin: 0 auto;
}

.main-content {
  margin: 10px;
  height: 100%;
  overflow-y: auto;
}

layout.css 样式

.side-logo {
  min-width: 60px !important;
  flex: 0 0 60px !important;
}
.side-title {
  flex: 0 0 180px !important;
  min-width: 180px !important;
}
.logo-style {
  float: left;
  margin: 4px;
  width: 40px;
}
.title-style {
  color: white;
  font-size: 18px;
  line-height: 48px;
  float: left;
  margin: 4px;
  font-weight: 700;
}
.trigger {
  width: 32px;
  font-size: 18px;
  line-height: 40px;
  padding: 0px;
  cursor: pointer;
  transition: color 0.3s;
  margin: 0 6px;
}

.trigger:hover {
  color: #5487eae0 !important;
}
.content-style {
  margin: 8px;
  padding: 4px;
  background: #fff;
  min-height: 280px;
}
.loginOut {
  margin: 6px 0px 0;
  font-size: 15px;
  cursor: pointer;
  border-radius: 50% !important;
  padding: 0px 0px !important;
  width: 30px;
}
.loginOut:hover {

}
.msg-style {
  background-color: #5487eae0;
}
.collased-menu-dropdown {
  transition: background 0.2s ease-in-out;
}

antd.css 调整组件库中的样式

.ant-btn {
  font-size: 14px !important;
  height: 28px !important;
  padding: 0px 10px !important;
  border-radius: 4px !important; 
  margin: 2px 8px 2px 0px;
}
.ant-btn::before {
  margin: 4px;
}
.ant-btn:hover { 
  opacity: 0.8;
}
.ant-form-inline .ant-form-item {
  margin: 0 8px 0 0 !important;
}
.ant-menu-dark .ant-menu-item-selected {
  border-radius: 4px !important; 
}
.ant-layout .ant-layout-header {
  padding-inline: 3px !important;
  background: #fff;
}
.ant-breadcrumb {
  padding: 8px 0 !important;
  font-size: 15px !important;
  width: calc(100% - 80px) !important;
  height: 50px;
}
.ant-tabs {
  width: calc(100% - 80px);
}
.ant-tabs-nav {
  height: 32px !important;
  margin-bottom: 8px !important;
}
.ant-tabs-nav .ant-tabs-nav-wrap {
  border-bottom: 1px solid #e6ebf3;
}
.ant-tabs-nav .ant-tabs-tab {
   border-top-right-radius: 4px !important;
   border-top-left-radius: 4px !important;
   padding: 8px 8px !important;
}
.ant-tabs .ant-tabs-tab-remove {
  margin: 2px -4px 0px 4px !important;
}
.ant-modal .ant-modal-header {
  margin-bottom: 20px;
}
