Practical, Tree-Shakeable implementation of Either (Result) and Option (Maybe) in TypeScript

Explore opportunities of functional programming through the prism of typescript and `fp-ts`

A tiny, zero-dependency library for handling synchronous and asynchronous results with robust error handling

A library for people with options and results.

Monad library for TypeScript. 🚀

🧩 Independent and decoupled Domain Layer, developed following the principles of DDD, to model business rules in a clear, consistent and reusable way.

@duplojs/utils is the TypeScript utility toolbox used across the DuploJS ecosystem. It focuses on strong typing, good DX, and small composable primitives that scale from simple helpers to full validation pipelines.

Fat Arrow is a library for Typed Functional Programming in TypeScript compatible with Node.js and all major browsers.

4th in-class project from the rocketseat nodejs course. In this one, it was approached the DDD approach for software developing. It was also implemented techniques like clean architecture, either for functional error handling, factory pattern, SOLID, etc.

This is an API that handles errors using the either pattern.
