+like [`shallow: false{:ts}`](./options#shallow) will have no effect.

+updating query state configured with `shallow: false{:ts}`, to notify the web server
+that the URL state has changed, if it needs it for server-side rendering other
+parts of the application than the static React bundle:
+
+```tsx title="src/main.tsx" /reloadPageOnShallowFalseUpdates/
+createRoot(document.getElementById('root')!).render(
+  <NuqsAdapter reloadPageOnShallowFalseUpdates>
+    <App />
+  </NuqsAdapter>
+)
+```
+

+Rails (Ruby), Laravel (PHP), Phoenix (Elixir) etc...
