title: useSearchParams
description: API Reference for the useSearchParams hook in the Pages Router.
---
`useSearchParams` is a hook that lets you read the current URL's **query string**.
`useSearchParams` returns a **read-only** version of the [`URLSearchParams`](https://developer.mozilla.org/docs/Web/API/URLSearchParams) interface.
```tsx filename="pages/dashboard.tsx" switcher
import { useSearchParams } from 'next/navigation'
export default function Dashboard() {
const searchParams = useSearchParams()
if (!searchParams) {
// Render fallback UI while search params are not yet available
return null
}
const search = searchParams.get('search')
// URL -> `/dashboard?search=my-project`
// `search` -> 'my-project'
return <>Search: {search}>
}
```
```jsx filename="pages/dashboard.js" switcher
import { useSearchParams } from 'next/navigation'
export default function Dashboard() {
const searchParams = useSearchParams()
if (!searchParams) {
// Render fallback UI while search params are not yet available
return null
}
const search = searchParams.get('search')
// URL -> `/dashboard?search=my-project`
// `search` -> 'my-project'
return <>Search: {search}>
}
```
## Parameters
```tsx
const searchParams = useSearchParams()
```
`useSearchParams` does not take any parameters.
## Returns
`useSearchParams` returns a **read-only** version of the [`URLSearchParams`](https://developer.mozilla.org/docs/Web/API/URLSearchParams) interface, or `null` during [prerendering](#behavior-during-prerendering).
The interface includes utility methods for reading the URL's query string:
- [`URLSearchParams.get()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/get): Returns the first value associated with the search parameter. For example:
| URL | `searchParams.get("a")` |
| -------------------- | --------------------------------------------------------------------------------------------------------------- |
| `/dashboard?a=1` | `'1'` |
| `/dashboard?a=` | `''` |
| `/dashboard?b=3` | `null` |
| `/dashboard?a=1&a=2` | `'1'` _- use [`getAll()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/getAll) to get all values_ |
- [`URLSearchParams.has()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/has): Returns a boolean value indicating if the given parameter exists. For example:
| URL | `searchParams.has("a")` |
| ---------------- | ----------------------- |
| `/dashboard?a=1` | `true` |
| `/dashboard?b=3` | `false` |
- Learn more about other **read-only** methods of [`URLSearchParams`](https://developer.mozilla.org/docs/Web/API/URLSearchParams), including the [`getAll()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/getAll), [`keys()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/keys), [`values()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/values), [`entries()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/entries), [`forEach()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/forEach), and [`toString()`](https://developer.mozilla.org/docs/Web/API/URLSearchParams/toString).
> **Good to know**: `useSearchParams` is a [React Hook](https://react.dev/learn#using-hooks) and cannot be used with classes.
## Behavior
### Behavior during prerendering
For pages that are [statically optimized](/docs/pages/building-your-application/rendering/automatic-static-optimization) (not using `getServerSideProps`), `useSearchParams` will return `null` during prerendering. After hydration, the value will be updated to the actual search params.
This is because search params cannot be known during static generation as they depend on the request.
```tsx filename="pages/dashboard.tsx" switcher
import { useSearchParams } from 'next/navigation'
export default function Dashboard() {
const searchParams = useSearchParams()
if (!searchParams) {
// Return a fallback UI while search params are loading
// This prevents hydration mismatches
return
Sort By
> ) } ``` ```jsx filename="pages/dashboard.js" switcher import { useRouter } from 'next/router' import { useSearchParams } from 'next/navigation' import { useCallback } from 'react' export default function Dashboard() { const router = useRouter() const searchParams = useSearchParams() const createQueryString = useCallback( (name, value) => { const params = new URLSearchParams(searchParams?.toString()) params.set(name, value) return params.toString() }, [searchParams] ) if (!searchParams) { return null } return ( <>Sort By
> ) } ``` ### Sharing components with App Router `useSearchParams` from `next/navigation` works in both the Pages Router and App Router. This allows you to create shared components that work in either context: ```tsx filename="components/search-bar.tsx" switcher import { useSearchParams } from 'next/navigation' // This component works in both pages/ and app/ export function SearchBar() { const searchParams = useSearchParams() if (!searchParams) { // Fallback for Pages Router during prerendering return } const search = searchParams.get('search') ?? '' return } ``` ```jsx filename="components/search-bar.js" switcher import { useSearchParams } from 'next/navigation' // This component works in both pages/ and app/ export function SearchBar() { const searchParams = useSearchParams() if (!searchParams) { // Fallback for Pages Router during prerendering return } const search = searchParams.get('search') ?? '' return } ``` > **Good to know**: When using this component in the App Router, wrap it in a `
