How to Use setTimeout in React Hooks

When building interactive applications with React, one common requirement is to provide feedback to users, such as displaying messages based on server responses. For instance, you might want to show a message that disappears after a few seconds. In this post, we’ll discuss how to implement the setTimeout function within React Hooks to achieve this functionality effectively.

The Problem

You may have encountered situations where you need to inform users about the result of their actions, like form submissions. For example, you might want to show a success or error message based on the server’s response, and automatically clear that message after a specified time.

Let's take a look at a typical scenario where this is needed: you send a form submission to a server and display a message based on the response. Here’s a sample snippet of the code you might be using:

While this code does a great job of handling the form submission, it falls short in clearing the message after a preset time. Let’s dive into how we can enhance this code with setTimeout.

The Solution: Implementing setTimeout

To automatically clear a message after a few seconds, you can add setTimeout in your handleSubmit function. Here's how to do it step-by-step:

Step 1: Update the handleSubmit Function

You need to modify the handleSubmit function to include setTimeout right after setting the message. This way, once the message is set, setTimeout will trigger and clear the message after 5 seconds.

Here’s the updated handleSubmit function:

Step 2: Clear Error Messages (Optional)

Sometimes, you may also want to clear error messages after the same duration. You can implement a similar setTimeout for error messages. Just ensure you position the timeout appropriately within your catch block if you want them cleared as well.

Alternative Approach

If you only want to clear the success message after 5 seconds but leave the error message intact, you can structure your handleSubmit function like this:

Conclusion

By incorporating the setTimeout function in your React Hooks, you can create a smooth user experience by providing timely feedback. It is straightforward and can be easily integrated into your existing logic. Remember to handle both success and error messages as needed based on your specific requirements.

Now you know how to properly utilize setTimeout with React Hooks to manage user feedback effectively. Happy coding!
