Can I use this skill to manage side effects like logging?

Yes, it includes patterns for Effect.sync and Effect.tap, which allow you to perform synchronous side effects or observe values without altering the main logic flow of your application.

Why should I use Effect.gen instead of standard piping?

Effect.gen uses JavaScript generator syntax to allow developers to write functional code that looks like imperative code, making complex sequential logic much easier to read and maintain while keeping full type safety.

How does this skill handle existing asynchronous code?

It provides patterns for Effect.promise and Effect.tryPromise to wrap existing Promises, ensuring that rejections are either handled as defects or converted into typed, recoverable errors.

What is the Effect type used in this skill?

The Effect type is a data structure with three parameters: Success (A), Error (E), and Requirements (R). it represents a program that can succeed with a value, fail with an error, or require specific dependencies to run.

API 开发

Simplifies the implementation of type-safe, composable functional programming patterns using the Effect library in TypeScript.

Effect Core Patterns provides Claude with the foundational knowledge and implementation patterns needed to build robust, production-grade applications using the Effect ecosystem. It enables the creation of highly composable, type-safe effects while managing errors, dependencies, and asynchronous logic through standardized constructors and generator-based composition. This skill is essential for developers moving away from traditional Promise-based error handling toward a more resilient functional architecture, ensuring that side effects are handled predictably and requirements are tracked at the type level.
