React Error Boundaries: Containing UI Crashes
An Error Boundary is like a try...catch block for React components, preventing a single UI crash from breaking your whole app. Use it to wrap components that might fail, showing a fallback UI instead of a white screen.
Think of an Error Boundary as a try...catch block for your component tree. It contains rendering errors within a specific part of the UI, preventing a single component's crash from taking down the entire application. Wrap it around features like a complex data grid or a third-party widget to gracefully handle failures by displaying a fallback UI. The main footgun is that they only catch errors during rendering, not in event handlers or async code, which still require standard JavaScript error handling.
