Effect Concurrency

Master concurrent execution in Effect using fibers. This skill covers forking, joining, interruption, parallel execution, and advanced concurrency patterns for building high-performance Effect applications.

Fibers Fundamentals

What are Fibers?

Fibers are lightweight virtual threads that execute effects concurrently:

import { Effect, Fiber } from "effect"

// Every effect runs on a fiber
const effect = Effect.succeed(42)
// When run, this executes on a fiber
