fp-ts-react
Helps your agent show functional patterns with fp-ts in React apps. Useful for state, forms, and data.
What it does
This tool helps build web applications with React using a more organized and safer programming style, especially for managing information and data. It offers practical patterns for handling states, forms, and data loading.
When to use it
- ✓When building React apps and wanting more safety in data management.
- ✓When needing to show different loading, error, or success states while fetching information.
- ✓When implementing forms that need to validate multiple pieces of information simultaneously.

When to Use This Skill
- When building React apps with fp-ts for type-safe state management
- When handling loading/error/success states in data fetching
- When implementing form validation with error accumulation
- When using React 18/19 or Next.js 14/15 with functional patterns
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.
FAQ
What is 'fp-ts'?
It's a library that brings functional programming concepts to JavaScript, helping to write safer and more organized code.
