ReactiveCocoa is a functional reactive programming framework and Cocoa UI binding layer. It provides a library for composing asynchronous data streams and managing application state through signals and functional operators. The framework functions as an Objective-C data binding library that links object properties and method calls to reactive streams using runtime dynamism and swizzling. It includes a utility to convert traditional key-value observation notifications into composable streams for synchronized state tracking. The project covers reactive UI programming by connecting interface el

Cycle.js is a functional reactive web framework and observable-driven UI library used for building web applications. It employs a reactive stream architecture that treats the document object model and side effects as continuous data streams, coordinating state and logic through a functional cycle. The framework distinguishes itself by isolating side effects from core logic using a system of drivers. This architecture maps external events to internal commands through a symmetric input-output pipeline, ensuring that the application remains a cycle of pure functions. The project provides capabi

ReactiveUI is a .NET MVVM framework and functional reactive programming library designed to decouple application state from the user interface. It functions as a reactive state management tool that uses observable streams to handle mutable data and asynchronous event-driven logic. The framework provides a cross-platform UI toolkit that abstracts business logic from platform-specific views. This enables the creation of consistent user interfaces across multiple .NET platforms by utilizing platform-agnostic abstractions. The system focuses on application state management and decoupled UI testi

Rx.NET is a reactive programming framework and library for the .NET ecosystem used to compose asynchronous and event-based programs. It provides an observable data stream API that treats live sequences of information as collections, allowing developers to coordinate asynchronous event workflows using a declarative syntax. The project functions as an extension of language integrated query patterns to asynchronous streams. This allows for the filtering and transformation of asynchronous notifications and event sequences through the application of query operators. The framework covers asynchron

Om is a frontend state management library and reactive user interface framework that integrates ClojureScript functional programming with the React virtual DOM rendering engine. It provides a bridge to build responsive web interfaces where visual elements automatically update when underlying application data changes. The project centers on a normalized state store that flattens complex data structures into a relational format. This data is accessed through a reader-based querying system, which decouples the user interface from the state by allowing components to declare specific data requirem

Bacon.js is a JavaScript functional reactive programming library used for coordinating complex asynchronous data flows. It functions as an observable event stream framework and an asynchronous data flow orchestrator, allowing developers to model events as declarative streams and properties. The library distinguishes itself through its ability to manage reactive state and synchronize timing across multiple sources. It provides specialized mechanisms for atomic state synchronization to prevent glitches in derived properties and offers advanced coordination strategies such as asynchronous stream

Azul ist ein nativer Desktop-Anwendungs-Builder und ein UI-Toolkit zur Erstellung leistungsstarker grafischer Benutzeroberflächen. Es nutzt ein funktionales und reaktives Programmiermodell zur Verwaltung von Layout und Zustand und ermöglicht die Entwicklung nativer Software durch ein CSS-basiertes Toolkit. Das Framework zeichnet sich durch die Verwendung der WebRender-Engine aus, um GPU-beschleunigtes Rendering bereitzustellen. Dies ermöglicht es dem System, komplexe Benutzeroberflächenelemente mit hoher Effizienz und Geschwindigkeit durch Hardwarebeschleunigung darzustellen. Das Projekt ermöglicht das Design von Desktop-Oberflächen unter Verwendung eines Document Object Models (DOM) und einer Styling-Syntax, die HTML und CSS ähnelt. Die Funktionalität deckt plattformübergreifendes Interface-Design und die Erstellung von Desktop-Oberflächen auf Basis von Webtechnologien ab.

Lettuce is a Redis client library for Java that provides synchronous, asynchronous, and reactive programming models for interacting with Redis databases. It supports standalone, cluster, sentinel, pub/sub, and search operations through a single thread-safe connection model that handles command execution without blocking the calling thread. The library distinguishes itself through its reactive streams integration with Project Reactor, enabling non-blocking, backpressure-aware data processing with Mono and Flux types. It offers cluster slot routing that transparently handles MOVED and ASK redir

RxGo is a functional reactive programming library and an implementation of ReactiveX for the Go language. It serves as an asynchronous stream processing toolkit designed to coordinate event-based programs and data flows using the observable pattern. The library enables the construction of asynchronous processing pipelines that transform, filter, and combine event sequences. It distinguishes itself through the use of functional operators to compose these pipelines and provides mechanisms for managing concurrent execution. The toolkit covers a broad range of stream orchestration capabilities,

RxPY ist eine Bibliothek für funktionale reaktive Programmierung und eine ReactiveX-Observable-Bibliothek für Python. Sie dient als asynchroner Stream-Prozessor und ereignisgesteuertes Koordinations-Framework zum Aufbau von Datenpipelines, die auf Zustandsänderungen oder Ereignisströme im Zeitverlauf reagieren. Die Bibliothek bietet ein Toolkit zur Komposition asynchroner und ereignisbasierter Programme mittels beobachtbarer Sequenzen und Operatoren. Sie zeichnet sich durch konfigurierbare Scheduler aus, die Nebenläufigkeit, Timing und Abonnement-Lebenszyklen verwalten. Das Projekt deckt ein breites Spektrum an Stream-Processing-Funktionen ab, einschließlich Datenaggregation, Filterung und Kombination. Es bietet Mechanismen für Event-Broadcasting, Sequenz-Buffering und Fehlerbehandlung sowie Werkzeuge zur Koordination beobachtbarer Streams mit asynchronen Event-Loops. Tests und Qualitätssicherung werden durch virtuelle Zeitsimulation, Marble-Diagramm-Modellierung und Emissionsverifizierung unterstützt.

Helidon is a Java microservices framework designed for building cloud-native applications.
