Hi @strange juniper. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In Next.js, you can refresh the current route using the router.refresh() method from the useRouter hook. This method makes a new request to the server, re-fetches data requests, and re-renders Server Components. The client will merge the updated React Server Component payload without losing unaffected client-side React (e.g. useState) or browser state (e.g. scroll position) source (https://nextjs.org/docs/app/api-reference/functions/use-router).
However, if you want to refresh the route upon query string change, you can watch for URL changes via componentDidUpdate as shown below:
componentDidUpdate(prevProps) {
const { pathname, query } = this.props.router
// verify props have changed to avoid an infinite loop
if (query.counter !== prevProps.router.query.counter) {
// fetch data based on the new query
}
}
source (https://nextjs.org/docs/pages/building-your-application/routing/linking-and-navigating)
Please note that the useRouter hook imported from next/router is not supported in the app directory but can continue to be used in the pages directory. In the app directory, you should use the new hooks imported from next/navigation: useRouter(), usePathname(), and useSearchParams() source (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration).
Also, keep in mind that these new hooks are only supported in Client Components. They cannot be used in Server Components.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Let me check the knowledge base for you. One moment! :books:
In Next.js 13, the useRouter hook from next/router is not supported in the app directory. Instead, you should use the new hooks imported from next/navigation: useRouter(), usePathname(), and useSearchParams() source (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration).
To listen for changes in the query string, you can use the useSearchParams hook. Here's an example:
'use client'
import { useEffect } from 'react'
import { usePathname, useSearchParams } from 'next/navigation'
export function NavigationEvents() {
const pathname = usePathname()
const searchParams = useSearchParams()
useEffect(() => {
const url = `${pathname}?${searchParams}`
console.log(url)
// You can now use the current URL
// ...
}, [pathname, searchParams])
return null
}
source (https://nextjs.org/docs/app/api-reference/functions/use-router)
This code will log the current URL whenever the pathname or search parameters change. You can replace the console.log statement with your own logic to refresh the component or perform other actions.
