How do I troubleshoot issues after upgrading React?
An example of an AI chatbot conversation about troubleshooting React upgrades.
I just upgraded my React app to the latest version, but now it's throwing errors. What should I do?
First, check the console for specific error messages. They can give you clues about what's wrong.
I see an error about 'React is not defined'. What does that mean?
This usually means that React is not properly imported in your files. Make sure you have 'import React from "react";' at the top of your components.
I fixed that, but now I'm getting a warning about deprecated lifecycle methods.
You might need to refactor your components to use the new lifecycle methods or hooks. Check the React documentation for guidance.
Thanks! Is there a way to test my app for compatibility with the new version?
Yes, you can use the React Upgrade Helper tool or run your app's tests to identify compatibility issues.
