{"library":"effect","type":"library","category":null,"description":"Effect-TS is a robust, type-safe functional programming library for TypeScript, providing a \"missing standard library\" for building highly concurrent, resilient, and performant applications. It centers around the `Effect` data type, which represents a description of a computation that may require resources (R), may fail with an error (E), and may succeed with a value (A). The library promotes a functional-first approach, emphasizing immutability, explicit error handling, and structured concurrency, leveraging TypeScript's type system to ensure correctness at compile-time. Currently stable at version 3.x (e.g., 3.21.1), `effect` maintains a regular release cadence with frequent patch and minor updates, reflecting active development and continuous improvement. It differentiates itself through its comprehensive ecosystem of modules (e.g., `Effect.Layer`, `Effect.Schema`, `Effect.Stream`) that integrate seamlessly, offering a complete solution for complex application logic, asynchronous operations, and resource management without runtime exceptions.","language":"javascript","status":"active","version":"3.21.1","tags":["javascript","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install effect","imports":["import { Effect } from 'effect'","import { Layer } from 'effect'","import { pipe } from 'effect'","import { Effect } from 'effect'; const program = Effect.gen(function* () { /* ... */ });"]},{"cmd":"yarn add effect","imports":[]},{"cmd":"pnpm add effect","imports":[]}],"homepage":"https://effect.website","github":"https://github.com/Effect-TS/effect","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/effect","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/effect/compatibility"}}
