vue3推荐使用依赖注入，而不是绑定全局变量

[cvpv]

我看到在示例demo中使用绑定全局属性来使得子组件this获取相关功能

// #ifdef VUE3
import {
	createSSRApp
} from 'vue'
export function createApp() {
	const app = createSSRApp(App)
	app.use(store)
	app.config.globalProperties.tui = tui;
	return {
		app
	}
}
// #endif

这在组合式api的调用中，必须使用内部方法getCurrentInstance 获取，具有风险
Because the instance is an internal instance that exposes non-public APIs. Anything you use from that instance can technically break between any release types, since they are not subject to semver constraints.

建议改为依赖注入写法

  app.provide('tui', tui) // vue3的推荐用法
