Why Do I Need to Refresh Routes in Next.js 14?
Before we dive into the how-to, let’s understand why route refreshing is essential in Next.js 14. When you navigate between routes in your app, Next.js uses client-side routing to render the new page. This approach provides a seamless user experience, but it can lead to issues when your routes rely on dynamic data or dependencies. If these dependencies change, your route might not update accordingly, resulting in a stale or outdated view.
In such cases, refreshing the route ensures that your app re-renders the page with the latest data, guaranteeing a consistent and accurate representation of your app’s state. So, let’s explore the ways to refresh routes in Next.js 14.
Method 1: Using router.refresh()
The most straightforward way to refresh a route in Next.js 14 is by using the router.refresh()
method. This approach is particularly useful when you need to re-render a page after a specific action, like updating a user’s profile information.
import { useRouter } from 'next/router'; function UserProfile() { const router = useRouter(); const handleUpdateProfile = async () => { // Update user profile logic here await updateProfile(); // Refresh the route to reflect the updated profile router.refresh(); }; return (); }User Profile
In this example, we use the useRouter
hook to access the router
object. Then, we call the refresh()
method after updating the user’s profile to re-render the page with the latest information.
Method 2: Using router.replace()
Another way to refresh a route is by using the router.replace()
method. This approach is similar to router.refresh()
, but it has a slight difference. router.replace()
replaces the current URL in the browser’s history, whereas router.refresh()
preserves the current URL.
import { useRouter } from 'next/router'; function ProductDetails() { const router = useRouter(); const { id } = useParams(); const handleUpdateProduct = async () => { // Update product logic here await updateProduct(id); // Refresh the route to reflect the updated product router.replace(`/products/${id}`); }; return (); }Product Details
In this example, we use router.replace()
to refresh the route after updating a product. This approach ensures that the URL in the browser’s history is updated, which can be useful when you need to preserve the URL structure.
Method 3: Using getStaticProps
with revalidate
If you’re using server-side rendering (SSR) or static site generation (SSG) in your Next.js 14 app, you can leverage the getStaticProps
method with the revalidate
option to refresh routes. This approach is particularly useful when you need to refresh a route based on external data or dependencies.
import { getStaticProps } from 'next'; function ProductList() { const products = getStaticProps({ async getStaticProps() { const res = await fetch('https://api.example.com/products'); const products = await res.json(); return { props: { products }, revalidate: 60, // Revalidate every 60 seconds }; }, })['props']; return (); }Product List
{products.map((product) => (
- {product.name}
))}
In this example, we use getStaticProps
to fetch a list of products from an external API. We also specify the revalidate
option to instruct Next.js to revalidate the route every 60 seconds. This ensures that the route is refreshed automatically when the external data changes.
Method 4: Using a Custom Hook
If you need more control over route refreshing or want to encapsulate the logic in a reusable hook, you can create a custom hook using the useEffect
hook and router.refresh()
.
import { useState, useEffect } from 'react'; import { useRouter } from 'next/router'; const useRefreshRoute = (delay = 5000) => { const router = useRouter(); const [refresh, setRefresh] = useState(false); useEffect(() => { const timeoutId = setTimeout(() => { setRefresh(true); }, delay); return () => clearTimeout(timeoutId); }, [delay]); useEffect(() => { if (refresh) { router.refresh(); setRefresh(false); } }, [refresh, router]); return () => setRefresh(true); }; function Dashboard() { const refreshRoute = useRefreshRoute(10000); // Refresh every 10 seconds return (); }Dashboard
In this example, we create a custom hook called useRefreshRoute
that takes an optional delay parameter. The hook uses useState
and useEffect
to implement a timer that triggers a route refresh after the specified delay. We then use this hook in our Dashboard
component to refresh the route every 10 seconds.
Best Practices for Route Refreshing in Next.js 14
When it comes to route refreshing in Next.js 14, there are some best practices to keep in mind:
- Use
router.refresh()
sparingly: Avoid usingrouter.refresh()
excessively, as it can lead to performance issues and slow down your app. - Optimize your route refreshing logic: Use caching, memoization, or other optimization techniques to minimize the number of times your route refreshing logic is executed.
- Test your route refreshing logic: Ensure that your route refreshing logic works as expected by testing it thoroughly in different scenarios.
- Monitor your app’s performance: Keep an eye on your app’s performance metrics to identify any issues related to route refreshing and optimize accordingly.
Conclusion
In conclusion, refreshing routes in Next.js 14 is a crucial aspect of building a robust and up-to-date app. By using the methods outlined in this article, you can ensure that your app stays fresh and accurate, even in the face of changing data or dependencies. Remember to follow best practices, test your logic, and monitor your app’s performance to provide the best possible experience for your users.
Method | Description |
---|---|
router.refresh() |
Re-renders the current page with the latest data. |

Frequently Asked Question
Get ready to learn the secrets of refreshing routes in Next.js 14 app router!
What is the best way to refresh routes in Next.js 14 app router?
You can use the `router.reload()` method provided by Next.js to refresh the current route. This method reloads the current page, which can be useful when you want to refresh the data or reset the state of the page.
How do I refresh a specific route in Next.js 14 app router?
To refresh a specific route, you can use the `router.replace()` method and pass the route path as an argument. For example, `router.replace(‘/dashboard’)` will reload the `/dashboard` route.
Is it possible to refresh all routes in Next.js 14 app router at once?
Yes, you can use the `router.refresh()` method to refresh all routes in your Next.js app. This method reloads the entire app, which can be useful when you want to reset the state of the entire app.
What is the difference between `router.reload()` and `router.replace()` methods?
The main difference is that `router.reload()` reloads the current page, while `router.replace()` replaces the current route with a new one. `router.replace()` is useful when you want to navigate to a new route, while `router.reload()` is useful when you want to refresh the current route.
Can I use `window.location.reload()` to refresh routes in Next.js 14 app router?
While `window.location.reload()` can be used to refresh the page, it’s not recommended in a Next.js app. This method can cause issues with client-side routing and may not work as expected with server-side rendering. Instead, use the `router` methods provided by Next.js to ensure proper routing and page reloads.
