You are currently viewing documentation for the canary channel of Next.js.
usePathname
usePathname
is a Client Component hook that lets you read the current URL's pathname.
app/example-client-component.tsx
'use client'
import { usePathname } from 'next/navigation'
export default function ExampleClientComponent() {
const pathname = usePathname()
return <p>Current pathname: {pathname}</p>
}
usePathname
intentionally requires using a Client Component. It's important to note Client Components are not a de-optimization. They are an integral part of the Server Components architecture.
For example, a Client Component with usePathname
will be rendered into HTML on the initial page load. When navigating to a new route, this component does not need to be re-fetched. Instead, the component is downloaded once (in the client JavaScript bundle), and re-renders based on the current state.
Good to know:
- Reading the current URL from a Server Component is not supported. This design is intentional to support layout state being preserved across page navigations.
- Compatibility mode:
usePathname
can returnnull
when a fallback route is being rendered or when apages
directory page has been automatically statically optimized by Next.js and the router is not ready.- When using
usePathname
with rewrites innext.config
orMiddleware
,useState
anduseEffect
must also be used in order to avoid hydration mismatch errors. See the rewrites example for more information.- Next.js will automatically update your types if it detects both an
app
andpages
directory in your project.
Parameters
const pathname = usePathname()
usePathname
does not take any parameters.
Returns
usePathname
returns a string of the current URL's pathname. For example:
URL | Returned value |
---|---|
/ | '/' |
/dashboard | '/dashboard' |
/dashboard?v=2 | '/dashboard' |
/blog/hello-world | '/blog/hello-world' |
Examples
Do something in response to a route change
app/example-client-component.tsx
'use client'
import { usePathname, useSearchParams } from 'next/navigation'
function ExampleClientComponent() {
const pathname = usePathname()
const searchParams = useSearchParams()
useEffect(() => {
// Do something here...
}, [pathname, searchParams])
}
Version | Changes |

v13.0.0 | usePathname introduced. |
