What problem does it solve?

Effect-based portable patterns address the fragility of raw promises in complex async code, providing self-contained utilities with predictable boundaries.

Core Features & Use Cases

• Wrap promises with try-based control and tagged errors for type-safe failure handling.
• Compose timeouts, retries, caching, and concurrency into robust flows that always resolve to a plain Promise.
• Instrument with tracing and pattern matching to improve observability and error diagnosis.

Quick Start

Create an Effect.fn-based function and execute it at the boundary with Effect.runPromise to obtain a standard Promise.
