Building an Error Handling Layer in React

React applications can encounter errors, and by default, React handles these errors by rendering a blank page, which negatively impacts user experience. To address this, developers can implement an error handling layer that centralizes error detection and handling, displaying helpful error messages instead of causing the application to crash. This can be achieved through error boundaries, which are React components that catch errors within their child component tree and display a fallback UI, or by using the react-error-boundary library, which simplifies error handling and supports both synchronous and asynchronous errors. React-error-boundary also allows error boundaries to be functional components and provides features like the useErrorHandler() hook for handling errors in asynchronous code. An effective error handling layer not only improves user experience by providing clear error messages but also consolidates error logic, making it easier to log, track, and fix errors in the application.
