A lightweight TypeScript/JavaScript library providing easy-to-use monads, interfaces, and lazy iterators.
Sweet-monads is a lightweight library that provides implementations of common monads (like Maybe and Either), interfaces, and lazy iterators for TypeScript and JavaScript. It solves the problem of handling optional values, errors, and asynchronous data flows in a functional, type-safe manner without introducing dependencies.
TypeScript and JavaScript developers working on applications that benefit from functional programming patterns, especially those needing robust error handling, optional value management, or efficient data iteration.
Developers choose Sweet-monads for its simplicity, zero dependencies, and ease of auditability—each monad is implemented in a single small file with clear TypeScript types, making it a reliable and minimal addition to any project.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Each monad is implemented in a single small file with no external dependencies, reducing bundle size and audit complexity, as highlighted in the README.
Provides well-defined TypeScript interfaces for all monads, ensuring consistent and safe type usage in TypeScript projects, as noted in the key features.
The code is clean and dependency-free, making it easy to audit and integrate into existing projects, aligning with the philosophy of simplicity and practicality.
Enables on-demand iteration over data sequences with minimal memory overhead, offering performance benefits for large datasets, as described in the key features.
Only includes basic monads (Maybe, Either, Identity, Iterator) and lacks advanced functional programming utilities like async monads or monad transformers, which might require additional libraries.
The README is minimal with few examples, and users must navigate to separate package directories for details, potentially slowing down onboarding and usage.
Does not offer out-of-the-box support for popular frameworks, meaning developers must handle integration manually for reactive or component-based architectures.
