How to Redirect to Homepage Using React Router and React Query

When developing applications, especially those that manage and display data, ensuring a seamless user experience is crucial. A common scenario arises when users delete an item, such as an invoice. After confirming the deletion, the interface should promptly reflect this change, ideally redirecting them back to a homepage or main list of items. However, a common problem occurs: the redirect happens before the data has been updated, leading to inconsistencies where deleted items still appear until the page is refreshed.

In this post, we will tackle this issue, showing you how to properly redirect to the homepage after deleting an item using React Router and React Query.

The Problem

You have an application displaying a list of invoices. Users can click on an invoice to view its details, and they are provided with an option to delete that invoice. Upon clicking delete, a modal appears to confirm their action. After confirming the deletion, users should be redirected to the homepage where they can see the updated list of invoices.

However, the code you currently have struggles with the redirect happening too early, causing the deleted invoice to still show up on the list until the entire page is refreshed. This situation is frustrating, and it can lead to confusion for users.

The Solution

Understanding useMutation

React Query provides a powerful useMutation hook that allows us to perform mutations (like deletions) while also keeping our UI in sync with the application state. It even supports callback functions that can provide more control after an operation succeeds.

Here are the key steps involved in the solution:

Set Up the Mutation: We will configure our useMutation to handle the deletion while using the onSuccess callback to invalidate the previous queries related to invoices.

Control the Redirect Based on Success: Instead of setting a redirect state immediately after the delete operation, we will check if the mutation was successful before redirecting.

Step-by-Step Implementation

Import Necessary Hooks

First, ensure you have all necessary imports at the beginning of your component:

Define the Mutation

Set up your mutation using useMutation. The key is including the onSuccess callback where you will invoke invalidateQueries.

Handle the Remove Action

Modify the removeInvoice function to only call mutation.mutate(id) without immediately redirecting.

Control the Redirect Logic

Now, we will check the mutation’s success status to determine if we should redirect:

Conclusion

By following the steps outlined above, you can effectively manage state changes within your application using React Router and React Query. This way, you ensure that your users have a seamless experience without confusion when an item is deleted and subsequently navigate back to view the updated list.

Implementing this pattern not only improves the UX but also leverages the powerful features of React Query to keep your UI state in sync with your server data effortlessly.

Remember, small adjustments can significantly enhance the user experience, and this one addresses a common challenge faced in many applic
