Global mounting in Vue.js 3
When you open main.js in the about project, you’ll notice something different. We no longer use the Global Vue instance to install plugins and other libraries.
Instead, you can see createApp method:
import { createApp } from 'vue'
import App from './App.vue'
const myApp = createApp(App)
myApp.use(/* plugin name */)
myApp.use(/* plugin name */)
myApp.use(/* plugin name */)
myApp.mount('#app')
The advantage of this feature is that it protects the Vue application from third party libraries/plugins we use which might override or make changes to the global instance — mostly by using Mixins.
Now with the createApp method, we install those plugins on a particular instance and not the global object.
