    Cats Effect

    Cats Effect

    The pure asynchronous runtime for Scala

    Cats-Effect is a high-quality functional programming library for Scala that provides a principled way to represent and manage side effects, particularly asynchronous and concurrent computations. It is part of the broader Typelevel ecosystem and builds on the abstractions from Cats (such as Functor, Monad, etc.). The core abstraction is the IO type (or effect types more generally), which encodes effectful computations in a pure, referentially transparent way.

    koka

    koka

    Koka language compiler and interpreter

    Koka is a strongly typed functional-style language with effect types and handlers. The core of Koka consists of a small set of well-studied language features, like first-class functions, a polymorphic type- and effect system, algebraic data types, and effect handlers. Each of these is composable and avoid the addition of “special” extensions by being as general as possible. Koka tracks the (side) effects of every function in its type, where pure and effectful computations are distinguished. ...

    A practical functional library for JavaScript programmers

    ...We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data. The primary distinguishing features of Ramda are: Ramda emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code. Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters. The parameters to Ramda functions are arranged to make it convenient for currying. ...

    Ponyfill is an explanatory project that defines and promotes a side-effect-free alternative to traditional polyfills. A ponyfill implements the behavior of a standard feature without modifying the native environment or pretending to be the built-in API. In JavaScript, this means importing and calling a normal module instead of patching globals such as Object, Array prototypes, or window. The approach reduces conflicts when specifications change or when multiple libraries implement the same feature differently. ...

    Laravel Sharp

    Laravel Sharp

    Laravel 10+ Content management framework

    Sharp is a content management framework, a toolset that provides help to build a CMS section in a website, with some rules in mind. The public website should not have any knowledge of the CMS, the CMS is a part of the system, not the center of it. In fact, removing the CMS should not have any effect on the project. Content administrators should work with their data and terminology, not CMS terms. I mean, if the project is about spaceships, space travels, and pilots, why would the CMS talk about articles, categories, and tags? Developers should not have to work on the front-end development for the CMS. Because life is complicated enough, Sharp takes care of all the responsive / CSS / JS stuff.

Each node sends it's output to another node, and so on and so forth to produce all kinds of effects. You can even implement your own custom nodes and plug them in however you like. Plug multiple nodes into the same input node for mixing and use the splitter node for complex routing.
