Next.js Favicon Not Showing – Solution
When a favicon is not showing in a Next.js application, there are a few possible reasons and solutions:
1. Incorrect Favicon Path
Ensure that the favicon file is located in the correct directory and that the path specified in the HTML is correct.
Example:
<link rel="icon" href="/favicon.ico" />
2. Clearing the Cache
If you previously had a different favicon, try clearing the browser cache to ensure that the updated favicon is displayed.
3. Favicon Generation
Make sure that the favicon file is in the proper format and has been correctly generated. It is recommended to use a favicon generator tool to ensure compatibility across different browsers.
4. Favicon Size and Format
Verify that the favicon has the correct size and format. The standard favicon size is 16×16 pixels for most browsers and 32×32 pixels for high-density displays (e.g., Retina). The favicon file should be in ICO or PNG format.
5. Next.js Configuration
Check the Next.js configuration files to ensure that the proper favicon configuration is set.
Example:
In the Next.js project root, create a next.config.js file if it doesn’t exist. Add the following code:
module.exports = {
images: {
favicon: 'path/to/your/favicon.ico',
}
}
Replace 'path/to/your/favicon.ico' with the actual path to your favicon file.
Additional Tips:
- Ensure that the favicon file is accessible and not restricted by any server-side or CDN configuration.
- Verify that the HTML code for the favicon is placed correctly within the
headsection of your HTML page.
