purify

What problem does it solve?

Purify provides ergonomic, production-ready primitives for functional programming in TypeScript, reducing boilerplate and improving type safety with algebraic data types, codecs, and async workflows.

Core Features & Use Cases

• Codecs for runtime validation: define and decode external data safely.
• Monadic data types: Maybe, Either, EitherAsync, MaybeAsync for robust error handling.
• Composable utilities: List, Tuple, Function aids for cleaner code.
• Use Case: Build a resilient API client that validates responses, handles errors, and composes async tasks declaratively.

Quick Start

Install the purify-ts package and import the modules in your TypeScript project:

• npm install purify-ts
• Then in your code: import { Maybe, Just } from 'purify-ts';
