Export App in Vite?

Question

Vue.js

In Vue I did something like this:

const app =
     createApp(App)
         .use(store)
         .use(router)
         .use(plugin1)
         .use(plugin2)
         .mount('#app')
 export default app

in order to use the progressbar plugin in some Axios, for example.
In Vite, it is no longer possible to export the App, it gives errors like "cannot access router before initalization". How can you export a constant from app?

Through Window it seems to work:

const app =
    const app = createApp(App)
         .use(store)
         .use(router)
         .use(plugin1)
         .use(plugin2)
         .mount('#app')
window.app = app

if someone has better options, then write
