title: Entire page deopted into client-side rendering
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
During static rendering, the entire page was deopted into client-side rendering by `useSearchParams` as there was no [Suspense boundary](/docs/app/api-reference/functions/use-search-params#static-rendering) that caught it.
|
|
|
|
If a route is statically rendered, calling `useSearchParams()` will cause the tree up to the closest [Suspense boundary](/docs/app/api-reference/functions/use-search-params#static-rendering) to be client-side rendered.
|
|
|
|
This allows a part of the page to be statically rendered while the dynamic part that uses `searchParams` can be client-side rendered.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
You can reduce the portion of the route that is client-side rendered by wrapping the component that uses useSearchParams in a Suspense boundary.
|
|
|
|
For example if `app/dashboard/search-bar.tsx` uses `useSearchParams` wrap the component in a [Suspense boundary](/docs/app/api-reference/functions/use-search-params#static-rendering) as shown in `app/dashboard/page.tsx`.
|
|
|
|
```tsx filename="app/dashboard/search-bar.tsx"
|
|
'use client'
|
|
|
|
import { useSearchParams } from 'next/navigation'
|
|
|
|
export default function SearchBar() {
|
|
const searchParams = useSearchParams()
|
|
|
|
const search = searchParams.get('search')
|
|
|
|
// This will not be logged on the server when using static rendering
|
|
console.log(search)
|
|
|
|
return <>Search: {search}</>
|
|
}
|
|
```
|
|
|
|
```tsx filename="app/dashboard/page.tsx"
|
|
import { Suspense } from 'react'
|
|
import SearchBar from './search-bar'
|
|
|
|
// This component passed as fallback to the Suspense boundary
|
|
// will be rendered in place of the search bar in the initial HTML.
|
|
// When the value is available during React hydration the fallback
|
|
// will be replaced with the `<SearchBar>` component.
|
|
function SearchBarFallback() {
|
|
return <>placeholder</>
|
|
}
|
|
|
|
export default function Page() {
|
|
return (
|
|
<>
|
|
<nav>
|
|
<Suspense fallback={<SearchBarFallback />}>
|
|
<SearchBar />
|
|
</Suspense>
|
|
</nav>
|
|
<h1>Dashboard</h1>
|
|
</>
|
|
)
|
|
}
|
|
```
