Router.refresh() refreshes the current route, makes a new request to the server, re-fetches data requests, and re-renders server components. Then what to do in case of client components?
server components gets cached and reflects the new data but if we have api call is in client components then that component is not showing updated data
#how to use router.refresh() for client components

Hi @rapid zenith. 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, the router.refresh() function is part of the useRouter hook and can be used to manually refresh a route. This function clears the Router Cache and makes a new request to the server for the current route. However, it does not affect the Data or Full Route Cache. The rendered result will be reconciled on the client while preserving React state and browser state. Here's an example of how to use it:
import { useRouter } from 'next/router'
export default function Page() {
const router = useRouter()
return (
<button type="button" onClick={() => router.refresh()}>
Click here to refresh
</button>
)
}

However, if you need to fetch data in a client component, you can call a Route Handler from the client. Route Handlers execute on the server and return the data to the client. This is useful when you don't want to expose sensitive information to the client, such as API tokens.
// Example of a Route Handler
export default function handler(req, res) {
res.status(200).json({ text: 'Hello' })
}

If you're facing issues with router.refresh() not invalidating the cache on the current page, it might be due to a known issue with Next.js as discussed in this Github Issue (https://github.com/vercel/next.js/issues/47812). A workaround suggested by a user is to use router.push('?${new Date().valueOf()}') to append a query string which effectively refreshes the data.
