VantUI 组件按需加载

项目采 用Vant 自动按需引入组件 (推荐)下 面安装插件介绍:

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

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);
`,10),e=[o];function t(c,r,D,y,F,C){return a(),n("div",null,e)}const u=s(p,[["render",t]]);export{A as __pageData,u as default};
