fp-ts-errors

This skill teaches you how to handle errors without try/catch spaghetti using fp-ts. It provides practical patterns for type-safe error handling in TypeScript, replacing try/catch with Either and TaskEither patterns. Ideal for building APIs or services that need explicit error types and accumulating multiple validation errors by treating errors as data instead of exceptions.

What It Does

Provides patterns for handling errors as values in TypeScript using the fp-ts library. It enables type-safe error handling, chaining operations that might fail, collecting multiple errors, and handling async operations with error handling.

When To Use

- When you want type-safe error handling in TypeScript
- When replacing try/catch with Either and TaskEither patterns
- When building APIs or services that need explicit error types
- When accumulating multiple validation errors
