How to Refresh Routes in Next.js 14 App Router? A Comprehensive Guide

Are you tired of stuck routes in your Next.js 14 app? Do you find yourself wondering why your routes aren’t updating as expected? Well, wonder no more! In this article, we’ll dive into the world of route refreshing in Next.js 14 and explore the various ways to tackle this common issue.

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 If these dependencies change, your route might not update accordingly, resulting in a stale or outdated view.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
      Update 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
      Update Product
    
  );
}

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
      Refresh Route
    
  );
}

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 using router.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.
