Functional Reactive Programming in Scala

Scala Problem Overview

Are there any libraries written for Scala enabling Functional Reactive Programming?

Scala Solutions

Solution 1 - Scala

See also Odersky et al.'s paper "Deprecating the Observer Pattern". It explains the library Scala.React, which was developed for the paper.

Solution 2 - Scala

There's reactive -- http://github.com/nafg/reactive. The repository currently contains two projects. reactive-core is a standalone FRP library. reactive-web builds on it to make it very easy to make very dynamic and interactive Lift webapps.

Solution 3 - Scala

https://github.com/Netflix/RxJava Functional Reactive Programming library for the JVM, developed by Netflix.

Solution 4 - Scala

There is Scala.Rx by Li Haoyi. In short, it aims to be a simpler, easy-to-use and more interoperable reimagination of (parts of) Scala.React.

Don't be misled by the Rx suffix. Scala.Rx has little to do with Reactive Extensions from .NET. Scala.Rx does not focus so much on asynchrony and event streams as rather time-varying values and the expression of functional dependencies with automatic change propagation.

Solution 5 - Scala

I don't Scala so don't know how good these are but here is a blog with comments that talk about FRP in scala: Functional Reactive Programming (FRP) in Scala (Fresca, ScalaFX) and here is the reddit that shows a stackoverflow conversation that led me to the above link.

Solution 6 - Scala

Coursera Principles of Reactive Programming course promotes RxScala.

> RxScala brings Reactive Extensions to Scala. Rx was first implemented > for .NET, and is now being implemented in Java. The RxScala project is > an adaptor for RxJava. Its code is in a subdirectory the RxJava > repository. > > This library is not yet finished. You have to expect breaking changes > in future versions.

Solution 7 - Scala

There is scala-reactive: http://github.com/erikrozendaal/scala-reactive

It is inspired by Microsoft's Reactive Extensions library, with an Observable trait taking the place of IObservable, and tailored to the Scala collections API as much Rx is to the LINQ API.

You have many many libraries. Here you have a list of many of them https://github.com/politrons/reactiveScala
