Troubleshooting React-Native Fast Refresh in Version 0.70.3

If you're a React-Native developer, you may have been excited about the Fast Refresh feature, enabling you to see your code changes instantly without losing the component state. However, it can be frustrating when Fast Refresh suddenly stops working, as reported by many users using version 0.70.3. If you're facing this issue and the page is not reloading automatically after code changes, don't worry! In this post, we’ll guide you through several troubleshooting steps to get your Fast Refresh back on track.

Understanding the Problem

When Fast Refresh stops functioning as expected, it can hinder your development process by not automatically reflecting your changes. This often causes delays and can be quite disruptive to your workflow. Let’s break down the solution into actionable steps so you can quickly restore seamless code reloading.

Quick Fix Steps to Restore Fast Refresh

Step 1: Clear the Cache

One of the most common solutions when facing issues in React-Native is to clear the cache. This step ensures that any corrupted or outdated cached data is removed, which can interfere with Fast Refresh functionality.

Step 3: Access the React-Native Dev Menu

Once the application is running, you need to access the React-Native Dev Menu on your mobile device. This can be done by shaking your device. Once the menu pops up, you’ll see options for enabling or disabling Fast Refresh.

Step 4: Enable Fast Refresh

In the Dev Menu, ensure that the Fast Refresh option is enabled. If it's already enabled, you may want to toggle it off and back on again. This can reset its state and potentially fix any lingering issues.

Conclusion

Fast Refresh is a remarkable feature that enhances your React-Native development experience, and it is important to address any issues you may encounter promptly. By following these structured steps — clearing the cache, running the app again, and managing the Dev Menu settings — you’ll be able to restore Fast Refresh in version 0.70.3 and get back to rapid iteration with your code.

If these steps didn’t fix the issue, consider checking your project setup or updating to a newer version if available. Happy coding!
