UniApp+vue3微信小程序怎么定义全局组件

import { createSSRApp } from "vue";
import  Vue from "vue";
import App from "./App.vue";
import store from "./store";

import newRequestLoading from '@/components/ccloading/ccloading.vue';

export function createApp() {
  const app = createSSRApp(App);
  app.use(store);
app.component('new-loading', newRequestLoading);

  return {
    app,
  };
}

然后就可以再任意的页面使用

<new-loading/>
