effect-and-errors

What problem does it solve?

Composes and propagates domain errors and HTTP-aware errors in Effect programs, enabling reliable failure handling across services.

Core Features & Use Cases

• Define domain errors with Data.TaggedError and implement HttpError for HTTP-boundaries.
• Standardize error propagation through Effect streams, with observability integration via spans.
• Use typed errors at boundaries to prevent leakage of internal state and to drive consistent HTTP responses.

Quick Start

Write a simple use case that defines a domain error with HttpError, and propagate it through an Effect-based workflow.
