Refreshing Data Fetched with a Custom Hook after Closing a Modal in React

In modern web applications, especially those built with React, user interaction is key to providing a great experience. Imagine a scenario where a user can select options from a dropdown menu, but they also need the ability to add new options on the fly. This is common for forms that rely on dynamic data.

The Problem: Data Refresh After Modal Closure

In your React application, you've implemented a custom hook to fetch data and populate a dropdown. You have a modal that allows users to add new options, but after successfully adding an option, you find that there’s no way to refresh the existing data without reloading the page. This becomes a hindrance to user experience.

Typical Implementation Challenge:

Using a Custom Hook: You have a custom hook called useGetFetch that fetches data based on the user's information.

Modal for Adding Options: Upon clicking a button, a modal opens, allowing users to submit new options.

Need for Refresh: After the modal closes post-submission, you want the dropdown to reflect the newly added options without a page refresh.

Solution: Implement a Refresh Mechanism

The core of the solution lies in enhancing the useGetFetch hook to support a "refetch" functionality. This essentially allows you to trigger the hook to re-fetch the data under certain conditions.

Step 1: Update Your useGetFetch Hook

You’ll adjust the custom hook to include a state variable that you can utilize to trigger a rerender.

Step 2: Use the Refetch Function in Your Parent Component

Next, you'll configure your parent component to utilize this refetching mechanic effectively.

How It Works

Refetch State: A new state variable shouldRefetch is added, which acts as a trigger to re-fetch data when you call the refetch function.

Dependency Management: The useEffect hook now listens for changes not just to user, but also shouldRefetch. When you call the refetch function, it will cause the effect to run again and fetch the new data.

User Experience: After submitting a new option through your modal and closing it, the dropdown will now automatically refresh to show newly added options, enhancing the overall user experience.

Conclusion

This approach allows you to implement a cohesive workflow in your React application where users can add options dynamically, and have the UI reflect those changes instantaneously without the need for page refreshes. Optimizing user interactions through intuitive data management is key to enhancing the usability of your applications.
