When should I use Either instead of Option?

Use Either when you need to represent a failure reason or error; use Option when a value is simply present or missing.

What is the main purpose of the fp-types-ref skill?

It provides a quick reference for the fp-ts library to help you choose the right types and implement functional patterns in TypeScript efficiently.

Does this skill help with async operations?

Yes, it provides patterns for Task and TaskEither, which are designed for handling asynchronous computations with or without error handling.

How do I handle null values using this skill?

The skill provides patterns like O.fromNullable to wrap potentially null or undefined values into safe Option types.

Is this a replacement for the official fp-ts documentation?

No, it is a quick-reference tool designed to speed up development by providing the most common types, imports, and patterns directly within Claude.

Aprendizaje y Documentación

Provides quick-reference guidance and decision-making logic for fp-ts types and functional programming patterns in TypeScript.

This skill serves as a concise documentation companion for developers using the fp-ts library in TypeScript. It assists in selecting the appropriate abstraction—such as Option, Either, Task, or TaskEither—based on operation characteristics like synchronicity and error handling. By offering common import snippets and one-line implementation patterns, it helps streamline the adoption of functional programming paradigms, reducing boilerplate and ensuring type safety in complex data flows.
