Fixing the Favicon Not Working Issue in Next.js Dynamic Routed Pages

When building applications with Next.js, you might encounter a common issue where the favicon doesn't display properly on dynamically routed pages. This can be frustrating, especially when static pages seem to work fine. If you've recently found yourself grappling with this problem, you're not alone! In this post, we will dive into the root cause of this issue and provide you with a simple solution to ensure your favicon is visible across all pages of your Next.js application.

The Problem Explained

You may have set up your _document.js file for your Next.js application correctly, as shown in the snippet below:

You've noted that your favicon is showing perfectly fine on static pages; however, for your dynamically routed pages (for instance, /folder/[id]), the favicon is missing. This creates an inconsistent user experience, and you're understandably seeking a resolution.

The Solution

The primary issue here lies in the link path to your icon file. In Next.js, any assets that you place within the public directory must be referenced using an absolute path that starts with a /. This means you need to correct the path in your _document.js file to properly access your favicon.

Steps to Fix the Favicon Path

Locate the Link to the Favicon in your _document.js file.

Modify the Path to start with a slash (/) like so:

Save Your Changes and rerun your application.

Test Across All Pages to confirm that the favicon now appears on both static and dynamic routes.

Why This Works

By using a leading slash in your path, you're ensuring that the browser looks for the favicon in the root of your public folder. This change informs Next.js to accurately locate the favicon associated with your application, irrespective of the routing type being utilized.

Conclusion

If you've found yourself battling with the frustrating issue of having a favicon that only appears on static pages, don't fret! Simply ensure that the path to your icon starts with a /, and you'll be back to having a consistent favicon across all pages in your Next.js application.
