# VantUI 组件按需加载
|
|
|
|
项目采
|
|
用[Vant 自动按需引入组件 (推荐)](https://youzan.github.io/vant/#/zh-CN/quickstart#fang-shi-yi.-zi-dong-an-xu-yin-ru-zu-jian-tui-jian)下
|
|
面安装插件介绍:
|
|
|
|
[babel-plugin-import](https://github.com/ant-design/babel-plugin-import) 是一款 `babel` 插件,它会在编译过程中将
|
|
`import` 的写法自动转换为按需引入的方式
|
|
|
|
## 安装插件
|
|
|
|
```bash
|
|
npm i babel-plugin-import -D
|
|
```
|
|
|
|
在`babel.config.js` 设置
|
|
|
|
```javascript
|
|
// 对于使用 babel7 的用户,可以在 babel.config.js 中配置
|
|
const plugins = [
|
|
[
|
|
"import",
|
|
{
|
|
libraryName: "vant",
|
|
libraryDirectory: "es",
|
|
style: true,
|
|
},
|
|
"vant",
|
|
],
|
|
];
|
|
module.exports = {
|
|
presets: [
|
|
["@vue/cli-plugin-babel/preset", { useBuiltIns: "usage", corejs: 3 }],
|
|
],
|
|
plugins,
|
|
};
|
|
```
|
|
|
|
## 使用组件
|
|
|
|
项目在 `src/plugins/vant.js` 下统一管理组件,用哪个引入哪个,无需在页面里重复引用
|
|
|
|
```javascript
|
|
// 按需全局引入 vant组件
|
|
import Vue from "vue";
|
|
import { Button, List, Cell, Tabbar, TabbarItem } from "vant";
|
|
Vue.use(Button);
|
|
Vue.use(Cell);
|
|
Vue.use(List);
|
|
Vue.use(Tabbar).use(TabbarItem);
|
|
```
