Stop Rewriting This React Form UX Logic

React form libraries like React Hook Form and Formik handle validation well but leave post-validation DOM behavior (focusing, scrolling, error summaries) to developers, who end up reimplementing the same logic repeatedly. The author created react-form-ux, a headless open-source package providing primitives like focusFirstError(), scrollToError(), and an ErrorSummary component that work with any form library.
