Centralizing API error handling in React involves using an Axios interceptor to normalize responses into a typed ApiError shape, automatically triggering global toasts and mapping field-level errors to forms via a dedicated hook.

RFC 7807 Problem Details integration standardizes frontend error management by normalizing API error responses into a safe, typed ApiError shape with an optional errors array, ensuring consistent error mapping across the React application.

Mapping server API errors to React form fields is handled by a useFormErrorHandler hook, which takes the normalized ApiError array and automatically maps the server validation errors directly to their corresponding form fields.

Displaying global API errors while keeping field errors localized requires wrapping the React app in an ErrorBoundary and using an ErrorAlert component for global display, alongside the useFormErrorHandler hook for field-specific mapping.

Yes, the centralized React error handling approach requires Axios, as it implements a generic Axios interceptor specifically to intercept and normalize API error responses into the RFC 7807 Problem Details format.

Handling both global toast notifications and form-level errors simultaneously is achievable through a single centralized setup that enables automatic global toasts for server errors while routing field-specific errors through the useFormErrorHandler hook.
