Handling Form Status in Next.js with useFormStatus()

In the realm of web development, creating dynamic user experiences during form submission is crucial for maintaining user engagement and satisfaction. One common challenge that developers face with Next.js is effectively using the useFormStatus() hook to manage the state of forms during user submissions. If you've encountered situations where useFormStatus() always returns false in your application, you're not alone.

In this guide, we will explore the problem with useFormStatus(), why it fails to function correctly, and how to implement a more robust solution for form management using useTransition().

The Problem: useFormStatus() Returns False

When attempting to dynamically change the UI during a form submission process, you might have set up a form component like this:

The intent here is straightforward: show a "Processing..." text on the button when the form is submitted. However, many developers have reported that the useFormStatus() hook fails to update as expected, leaving the button's text stuck on "Submit".

A Closer Look at the Current Implementation

When you incorporated the Button component within a separate file using the following code:

You likely noticed that despite the submission, the button label does not change to "Processing...".

Finding the Solution: Using useTransition()

An alternative approach to solving the issue without sticking strictly to the action keyword in your form is to utilize the useTransition() hook. Here's how you can implement it:

Utilizing useTransition()

Set Up the Hook: Begin by importing the useTransition from React. You'll create a state that defines whether the form submission is pending or not.

Update the Form Submission Logic: Modify your onSubmit function to ensure that it executes within the startTransition callback.

Conclusion

By leveraging useTransition(), you can effectively manage the state of your forms in Next.js. This solution not only resolves the issue of useFormStatus() always returning false but also enhances the user experience during form submissions by providing real-time feedback.

If you’re building dynamic user interfaces within Next.js, consider implementing the strategies mentioned in this guide. They'll allow for smoother form handling and robust state management that enriches your application's interactivity.
