How to Prevent Data Loss During Page Refresh in React Applications

If you're developing a product detail page using React and encounter data loss when refreshing the page, you're not alone. This is a common issue developers face—especially when relying solely on client-side state management or routing for data retrieval. In this guide, we’ll explore the reasons behind this issue and the solutions you can implement to prevent data loss effectively.

Understanding the Problem

When a user navigates to a product page by clicking on a product card, the product's details are displayed based on the provided ID in the URL. However, upon refreshing the page, React may not retain the product data as expected, leading to an error due to the loss of context. This happens because the relevant data might only exist in memory (i.e., state), which gets cleared on a page reload.

Key Observations:

The product ID is lost during the refresh.

The application cannot fetch the corresponding product details.

Users experience errors or blank pages instead of the intended product information.

Solutions to Prevent Data Loss

There are two primary approaches you can take to effectively handle this issue during page refreshes.

1. Using Session Storage/Local Storage

One way to retain state across refreshes is by saving the required data in the browser’s session storage or local storage. Here’s how you can implement it:

Steps to Implement:

When the data changes (for instance, when the product is loaded), store it in session storage or local storage.

Retrieve data from storage when the component mounts.

2. Making Another API Call on Detail Page Load

This approach involves fetching the product data from your backend API each time the detail page is loaded. This way, even if the session is cleared, the application can continue retrieving necessary data seamlessly.

Steps to Implement:

Check if data is already loaded.

If not, make a request to your backend service to fetch the product details based on the ID in the URL.

Example Code:

Conclusion

Preventing data loss during page refresh in React applications is crucial for maintaining a smooth user experience. By utilizing session storage/local storage or making API calls to retrieve the data, you can ensure that your application behaves as expected even when users refresh their browsers. Choose the approach that best fits your application’s architecture and user experience goals.
