Changing Button State in React During API Calls: A Simple Solution

Creating dynamic and responsive user interfaces in React often involves making API calls. One common scenario is changing the state of a button while waiting for a response. In this guide, we’ll tackle an issue faced by many React developers: How do you change the state of a button from Write to Loading... while making an API call?

The Problem

You're working on a React application and need the button to show Loading... while waiting for data from the server. You want the button to revert back to Write once the data is retrieved. This behavior enhances the user experience by providing feedback during the request period.

The Solution

Let’s dive into the solution, broken down into manageable steps. The key components of your implementation will include updating component state appropriately and displaying the correct button text based on that state.

Step 1: Modify the HandleApiCall Function

First, we need to ensure that you properly set the loading state. Your HandleApiCall function should update the state at the beginning of the function and reset it after the API call completes. Here's how to structure it:

Step 2: Implement the Button Rendering Logic

Instead of having two separate button elements, we can simplify the JSX by using a single button. This way, it will dynamically display the text based on the loading state. Here’s the updated rendering logic for your button:

Step 3: Understand the Changes

Now let's break down these changes to understand why they are effective:

Asynchronous Handling: The async keyword before the HandleApiCall function allows us to use await for the Axios call. This makes your code easier to read and manage by eliminating the "then" chaining.

Error Handling: Including a try-catch block ensures that your application gracefully handles any errors that may arise during the API call.

State Management: The setState method updates the loading state; the button dynamically changes its label based on this state without needing separate button elements.

No Await on setState: You don't need to use await with setState, as it does not return a promise, meaning you can call it directly without awaiting.

Conclusion

By following these steps, you can easily change the button state in your React app to enhance user interaction during API calls. This solution is straightforward and leverages React's powerful component state management. Implementing this effectively will not only improve your app's responsiveness but also provide a better experience for your users.

Now, go ahead and implement this in your code! You'll find that handling button states during asynchronous operations can be both simple and efficient.
