Solving the Caching Issue in Gatsby JS: A Comprehensive Guide

Introduction

If you have developed a Gatsby JS application, you might have encountered the issue of components not reloading their data upon navigation. One common scenario involves the Testimonials component, which does not display its content when users navigate back to the homepage from another page. Users often see a blank area where the Testimonials section should be. This can detrimentally affect the user experience, and resolving this caching issue is essential.

In this guide, we will dive into the problem, analyzing what's happening behind the scenes in your Gatsby application and how you can effectively address it.

Understanding the Issue

In your situation, it appears that the Testimonials data, fetched from Strapi and displayed on your Gatsby app, is not rehydrating correctly when navigating back to the homepage. This is primarily caused by direct interactions with the DOM without integrating with React's virtual DOM. Specifically, jQuery is being used, which manipulates the document without React's mediation, leading to issues in rehydrating the component correctly.

Solution Overview

Identifying the Problem

The culprit behind the blank Testimonials section on return to your homepage is likely due to reliance on global objects like window or document, combined with the way jQuery interacts with the DOM. When React attempts to rehydrate these components, it has difficulties because they are not correctly referenced in the React environment.

Recommended Solution: Avoid jQuery and Utilize React-Friendly Approaches

Remove jQuery: The first recommendation is to eliminate jQuery from your project. Utilizing jQuery for DOM manipulation contradicts React’s design and leads to complications with hydrating React components once they are mounted.

Implement a Loader Across the Site: To ensure a seamless user experience while data is loading, consider implementing a loader that manages state and renders accordingly. Below is an example implementation of a simple loader using React hooks:

Implementing the Changes

Step-by-Step Guide

Start by removing any jQuery code or libraries from your project.

Ensure all component communication flows through React state management.

Replace the existing layout with the updated loader logic as shown above. This will give users a smooth experience while data is fetched.

Test Your Changes

After implementing the solutions, navigate through your application and ensure that everything works as expected. Check the Testimonials section by moving between pages and confirming that data is consistently displayed without the need to refresh.

Conclusion

By following the steps outlined in this guide, you can effectively eliminate the caching issues you're experiencing with your Gatsby JS application. Adopting a React-centric approach while avoiding jQuery will enhance not only the user experience but also the performance of your application as a whole.
