Functional Programming in React Practical patterns for React apps. No jargon, just code that works. --- Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. When to Use What Situation Use ----------- ----- Value might not exist Option<T> Operation might fail (sync) Either<E, A> Async operation might fail TaskEither<E, A> Need loading/error/success UI RemoteData<E, A> Form with multiple validations Either with validation applicative Dependency injection Context + ReaderTaskEither Prevent re-renders with fp-ts useMemo or fp-ts-react-stable-hooks --- Limitations Use this skill only when the task clearly matches the scope described above. Do not treat the output as a substitute for environment-specific validation, testing, or expert review. Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
