effect-patterns

What problem does it solve?

This Skill demystifies Effect-TS development by providing canonical patterns and best practices for services, schemas, and state management with effect-atom. It helps developers build robust, type-safe, and maintainable applications, avoiding common pitfalls and ensuring architectural consistency.

Core Features & Use Cases

• Service Definition: Guides on choosing the right Effect-TS service pattern (Effect.Service, Context.Tag) for various scenarios.
• Atom-as-State: Enforces the Atom.make() pattern for React state, avoiding Effect.Ref complexity and ensuring reactive, performant UIs.
• Schema & Observability: Provides patterns for Schema.TaggedStruct, Schema.TaggedClass, and Effect.withSpan for robust domain modeling, data validation, and tracing.
• Use Case: When designing a new backend service or a complex state management system in a React application, invoke this Skill to get the recommended Effect-TS service definition, Atom-based state management, and error handling patterns, ensuring your architecture is sound from the start.

Quick Start

Explain the recommended Effect-TS service definition pattern for a new data fetching service that uses effect-atom for state.
