effect-patterns-concurrency

What problem does it solve?

This Skill provides a curated set of Effect-TS concurrency patterns to help developers design robust, scalable, and maintainable concurrent applications. It tackles the complexity of coordinating many fibers, controlling resource usage, and reacting to asynchronous events.

Core Features & Use Cases

• Race and timeout patterns for fastest result and deadline enforcement
• Semaphore-based rate limiting to cap concurrent tasks
• Shared state coordination with Ref and atomic updates
• Parallel work with Effect.all and forEach using controlled concurrency
• Fan-out/fan-in and barrier synchronization with Latch
• Event distribution via PubSub and robust producer-consumer pipelines with Queue
• Lifecycle and background task patterns using runFork, Scope, and graceful shutdown

Quick Start

Run a minimal script that imports Effect and uses Effect.race to compare two tasks, then applies a bounded concurrency pattern to limit parallel executions. This demonstrates the core primitives of the concurrency patterns in this skill and lets you tweak latency and concurrency to observe behavior.
