Vue3注册全局组件

1. Vue3全局组件注册

• components文件夹下新建index.js文件，统一引入需要注册的组件

import CustomCheck from "./CustomCheck.vue";
import CustomDialog from "./CustomDialog.vue";
const components = {
  install(app) {
    app.component("CustomCheck", CustomCheck);
    app.component("CustomDialog", CustomDialog);
  },
};
export default components;

• main.js中引入并使用

import { createApp } from "vue";
import App from "./App.vue";
const app = createApp(App);

// 引入使用
import commonUi from "./components/index.js";
app.use(commonUi);

2. Vue2全局组件注册

• 前面引入方法与Vue3一致，区别是使用

import Vue from "vue";

// 使用组件
import commonUi from "./components/index.js";
Vue.use(commonUi);
