effect-patterns-error-handling

What problem does it solve?

This Skill addresses the challenge of implementing robust, domain-aware error handling in Effect-TS applications, enabling precise recovery strategies and clear error context.

Core Features & Use Cases

• Domain-aware error types with tagged errors
• Per-error recovery strategies and context-rich error propagation
• Patterns for propagation, retry, and user-friendly fallbacks across network, validation, and business logic

Quick Start

• Define custom error classes (e.g., NetworkError, ValidationError) and decide recovery strategy for each
• Use Effect.mapError, Effect.catchTag, and Effect.catchAll to transform and recover
• Apply retry/backoff and fallback strategies in end-to-end flows
