JeecgBoot实战 - 按需加载方案
一、Ant-Design-Vue 按需加载
1.创建js文件 src/components/lazy_antd.js
import Vue from 'vue'
// base library
import {
ConfigProvider,
Layout,
Input,
InputNumber,
Button,
Switch,
Radio,
Checkbox,
Select,
Card,
Form,
Row,
Col,
Modal,
Table,
Tabs,
Icon,
Badge,
Popover,
Dropdown,
List,
Avatar,
Breadcrumb,
Steps,
Spin,
Menu,
Drawer,
Tooltip,
Alert,
Tag,
Divider,
DatePicker,
TimePicker,
Upload,
Progress,
Skeleton,
Popconfirm,
PageHeader,
Result,
Statistic,
Descriptions,
message,
notification,
Empty,
Tree,
TreeSelect
} from 'ant-design-vue'
import Viser from 'viser-vue'
Vue.use(ConfigProvider)
Vue.use(Layout)
Vue.use(Input)
Vue.use(InputNumber)
Vue.use(Button)
Vue.use(Switch)
Vue.use(Radio)
Vue.use(Checkbox)
Vue.use(Select)
Vue.use(Card)
Vue.use(Form)
Vue.use(Row)
Vue.use(Col)
Vue.use(Modal)
Vue.use(Table)
Vue.use(Tabs)
Vue.use(Icon)
Vue.use(Badge)
Vue.use(Popover)
Vue.use(Dropdown)
Vue.use(List)
Vue.use(Avatar)
Vue.use(Breadcrumb)
Vue.use(Steps)
Vue.use(Spin)
Vue.use(Menu)
Vue.use(Drawer)
Vue.use(Tooltip)
Vue.use(Alert)
Vue.use(Tag)
Vue.use(Divider)
Vue.use(DatePicker)
Vue.use(TimePicker)
Vue.use(Upload)
Vue.use(Progress)
Vue.use(Skeleton)
Vue.use(Popconfirm)
Vue.use(PageHeader)
Vue.use(Result)
Vue.use(Statistic)
Vue.use(Descriptions)
Vue.use(Empty)
Vue.use(Tree)
Vue.use(TreeSelect)
Vue.prototype.$confirm = Modal.confirm
Vue.prototype.$message = message
Vue.prototype.$notification = notification
Vue.prototype.$info = Modal.info
Vue.prototype.$success = Modal.success
Vue.prototype.$error = Modal.error
Vue.prototype.$warning = Modal.warning
process.env.NODE_ENV !== 'production' && console.warn('[jeecg-boot-vue] NOTICE: Antd use lazy-load.')2.修改配置文件 babel.config.js增加插件配置
plugins: [
[ "import", {
"libraryName": "ant-design-vue",
"libraryDirectory": "es",
"style": "css"
} ]
]参考图
3.修改main.js 引入配置文件 src/components/lazy_antd.js，同时注释掉原来的 ant-design-vue引入。
src/main.js
// 按需引入所需组件，统一引入文件
import './components/lazy_antd'
4.package.json引入依赖babel-plugin-import
"babel-plugin-import": "^1.13.0"
备注： 组件如果有缺少，需手工添加。

二、Icon按需加载
- 创建js文件 src/icons.js
// src/icons.js
// export what you need
export {
default as SmileOutline
} from '@ant-design/icons/lib/outline/SmileOutline';
export {
default as MehOutline
} from '@ant-design/icons/lib/outline/MehOutline';
// export what antd other components need
export {
default as CloseOutline
} from '@ant-design/icons/lib/outline/CloseOutline';
// and other icons...2.修改配置文件 vue.config.js
在 chainWebpack: (config) => { config.resolve.alias 新增一个配置
.set('@ant-design/icons/lib/dist$',resolve("src/icons.js"))参考图
备注： 图标如果有缺少，需手工添加。
