+---
+
+# `onNuxtReady`
+
+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.
+
+```ts
+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.
