The onNuxtReady composable allows running a callback after your app has finished initializing. It is ideal for running code that should not block the initial rendering of your app.

export default defineNuxtPlugin(() => {
onNuxtReady(async () => {
const myAnalyticsLibrary = await import('my-big-analytics-library')
// do something with myAnalyticsLibrary

It is 'safe' to run even after your app has initialized. In this case, then the code will be registered to run in the next idle callback.

onNuxtReady only runs on the client-side.
