Effect-TS/effect

Build production-ready applications in TypeScript

Effect is a TypeScript library for building production-grade, type-safe applications. It tackles hard problems at scale with typed errors, dependency injection, structured concurrency, scheduling, tracing/OpenTelemetry observability, and unified schema validation. It's a monorepo shipping the core effect package plus integration packages (e.g., SQL drivers) in synchronized versions.

Why now: Effect 4.x has just been released as a long-term support (LTS) release with a three-year support guarantee and a migration guide for teams coming from 3.x.

Who it is for: TypeScript teams building large, long-lived production applications who want robust error handling, concurrency, and observability in their codebase.
