What is the benefit of using tagged error types?

Tagged error types enable pattern matching and exhaustive type checking, ensuring that developers handle every possible error case defined in the application's domain.

When should I use Effect.either instead of catchAll?

Use Effect.either when you want to transform the result into an Either type to handle the error as a value (Left) in your logic without immediately exiting the Effect pipeline.

How do I handle specific error types using this skill?

The skill guides you in using tagged unions for errors, allowing you to use operators like catchTag to selectively handle specific errors based on their unique _tag identifier.

What is the difference between Expected Errors and Defects in Effect?

Expected errors are tracked in the type system and represent recoverable failures, while defects are unexpected bugs or programming errors that cause the program to crash or fail unexpectedly.

Does this skill support retrying failed network requests?

Yes, it provides implementation patterns for Effect.retry, including linear and exponential backoff schedules to handle transient failures gracefully.

API開発

Implements type-safe error management patterns for Effect TS applications to ensure robust and predictable code logic.

This skill provides specialized guidance for managing errors within the Effect ecosystem, distinguishing between expected domain errors and unexpected defects. It enables the implementation of advanced functional patterns like tagged error unions, selective error recovery using catchTag, and transformations using Either and Option types. By leveraging these patterns, developers can eliminate unhandled exceptions and create self-documenting, resilient applications that treat failures as first-class citizens in the type system, significantly improving code reliability and developer experience.
