Debugging and error tracking are crucial aspects of React Native app development. Developers spend most of their time debugging existing code rather than writing new code. Debugging strategies include using a dedicated debugging tool, such as the React Native Debugger, which provides additional features like a built-in UI inspector, Redux debugger, network inspector, and performance profiler. The Expo Debugger is also a useful tool that displays error messages, marks erroneous parts of the code, and shows a cleaner stack trace on emulators. The React Developer Tools Chrome extension or npm install command can be used to debug React Native apps in a browser. These tools help developers inspect UI elements, debug component state and props, and view network requests. Moreover, they provide features like performance monitoring and profiling. Error tracking is also essential, as it helps identify faulty plugin errors, crashes, and other issues that may occur during runtime. Tools like Sentry can be used to track live production errors, providing deep actionable insights to fix them early in release cycles. By using these tools and strategies, developers can effectively debug and track errors in their React Native apps.
