What problem does it solve?
This Skill helps developers understand and use the core Effect type in Effect-TS.
Core Features & Use Cases
- Understand the Effect<Success, Error, Requirements> type and why effects are descriptions, not executions.
- Create effects from synchronous and asynchronous sources (Effect.succeed, Effect.fail, Effect.promise, Effect.try, Effect.tryPromise).
- Compose effects with pipe and Effect.gen for readable sequential code and generator syntax.
- Run effects with runtime methods like Effect.runPromise, Effect.runSync, Effect.runPromiseExit.
- Follow best practices: typed errors, avoid throwing, use typed schemas for input data, and exploit dual APIs (data-first and data-last).
Quick Start
Create a small program that succeeds with a value and run it using Effect.runPromise to observe the result.
