Fixing Page Refresh Issues with React Router DOM in Your Online Store

When developing an online store using React and react-router-dom, you may encounter a frustrating issue where updating search parameters does not reflect changes in the catalog after a page refresh. This problem can lead to poor user experience as the catalog does not register updated search queries.

In this post, we will explore the root of this issue and demonstrate an effective solution to ensure your search functionality behaves as expected.

Understanding the Problem

The crux of the issue is that your application is duplicating URL search parameters into local React state. This creates a synchronization challenge—whenever the URL is updated, the local state doesn't refresh accordingly, leading to discrepancies between the visually displayed state and the URL state.

In your catalog implementation, the search parameters should automatically update based on user inputs. However, introducing a local state alongside the URL state creates an unnecessary layer of complexity.

The Solution

We will refactor your components to eliminate any redundant local state and directly read and update the search parameters using useSearchParams from react-router-dom. This will simplify your components and ensure they react dynamically to changes in the URL.

Step 1: Update the SearchInput Component

The SearchInput component should use useSearchParams directly for reading and setting the searchTerm query parameters.

Here is the revised code:

Step 2: Revise the useFilters Hook

Next, adjust the useFilters hook to utilize useSearchParams. This will enable it to read from and manage the search parameters effectively.

Here’s how your updated useFilters hook will look:

Conclusion

By following the steps outlined above, you can effectively fix the page refresh issue in your online store. The key takeaway is to avoid duplicating search parameters into local state; instead, manage them directly from the URL state. This not only reduces potential bugs and inconsistencies but also enhances the clarity and maintainability of your code.

With these adjustments, your application will now properly react to URL changes, improving the user experience and functionality of your online store.

Remember, when using React, keeping your component state in sync with the URL is paramount for creating a seamless user experience.
