How to Interchange Between Two Unique Favicons in Your Gatsby Project

As web developers, one of the small yet significant aspects of creating an engaging user experience is the favicon—that little icon displayed in the browser tab. If you're working on a Gatsby project and want to interchange between two unique favicons, you may find yourself facing a few challenges.

In this guide, we’ll dive into how you can achieve this functionality effectively.

Understanding the Favicon Challenge in Gatsby

Gatsby projects often utilize the gatsby-plugin-manifest to manage favicons easily. This plugin generates a single favicon for your site, simplifying the setup process. However, it has its limitations:

Static Configuration: gatsby-plugin-manifest does not support dynamic behavior. Therefore, you cannot swap favicons using the settings defined in your gatsby-config.js file.

Client-Side Logic: If you want to toggle between favicons based on user interaction, you will need to implement additional client-side logic, which this plugin alone does not facilitate.

Solution: Using React Helmet to Manage Favicons

Fortunately, you can leverage the power of the react-helmet library to create a dynamic favicon swapping mechanism. react-helmet allows you to manage the head tag of your document, enabling you to change the favicon on the fly. Here’s how you can implement it.

Step-by-Step Implementation

Install React Helmet:

If you haven't already installed react-helmet, you can do so via npm:

Set Up Your Component:

Now, create your component where you want the favicon swapping logic to reside. You will need to use local state to manage which favicon is currently active.

Integrate into Your Application:

Now, simply add the FaviconSwitcher component into your application wherever you need the favicon toggle feature to be.

Summary

To recap, while gatsby-plugin-manifest provides a straightforward way to set a favicon, it lacks the capability for dynamic swaps based on user interaction. By incorporating react-helmet, you can manage your favicons effectively. This approach allows you to:

Dynamically switch between favicons using client-side logic

Present a more engaging user experience with minimal additional overhead

If you're exploring the option of a secondary or alert favicon during your development, this method can significantly simplify the implementation.
