Top 23 Functional Reactive Programming Open-Source Projects

  • ios-oss

    Kickstarter for iOS. Bring new ideas to life, anywhere.

  • ReactiveUI

    An advanced, composable, functional reactive model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming. ReactiveUI allows you to abstract mutable state away from your user interfaces, express the idea around a feature in one readable place and improve the testability of your application.

    ReactiveUI is based on Rx and very popular in the .Net world: https://www.reactiveui.net/.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • mobius

    A functional reactive framework for managing state evolution and side-effects.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • reflex

    Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. (by reflex-frp)

    • Project mention: On inheritance and why it's good Rust doesn't have it | /r/rust | 2023-12-08

    There's other people around here who would like to know your opinion about these GUI frameworks! I haven't written a GUI in Rust personally, but my favorite GUI framework is not at all OOP: https://reflex-frp.org/

  • Scala.Rx

    An experimental library for Functional Reactive Programming in Scala

  • githut

    Github Language Statistics

    • Project mention: Include <Rules> | news.ycombinator.com | 2024-02-04

    This is the best measure I've found:

    https://madnight.github.io/githut/#/pushes/2023/4

    Unfortunately it doesn't have new projects, but it does seem like C++ peaked a couple of years ago and is starting to trend down. "Plummeting" is clearly an exaggeration though.

  • RxScala

    RxScala – Reactive Extensions for Scala – a library for composing asynchronous and event-based programs using observable sequences

  • signia

    Reactive signals that scale, by tldraw.

    • Project mention: Which state management library should I use? | /r/reactjs | 2023-05-18

    For signals, Signia or Legend State.

  • reflex-platform

    A curated package set and set of tools that let you build Haskell packages so they can run on a variety of platforms. reflex-platform is built on top of the nix package manager.

    We used reflex-frp, so our app was a webview that worked on localhost and Android. The docs say it also works on iOS but we don't have an iPhone.

    The process was learning Functional Reactive Programming, then learning reflex-frp, then getting a contract with obsidian (creators of reflex) for one hour a week where we could ask questions.

    ( https://github.com/reflex-frp/reflex-platform )

    We had a grant requirement to create a phone client for Tahoe-LAFS, a Python application with a bunch of dependencies, including ZFEC, a forward error correction library.

    ( https://tahoe-lafs.readthedocs.io/ )

    ( https://github.com/tahoe-lafs/zfec/ )

    We needed bug for bug compatibility with the Python codebase, so I ran Tahoe on localhost and tested the Haskell client against the Python server. We used servant to build the API, since it builds both client and server side from the same description.

  • Laminar

    Simple, expressive, and safe UI library for Scala.js (by raquo)

    • Project mention: Ask HN: Those making $500/month on side projects in 2024 – Show and tell | news.ycombinator.com | 2024-01-23

    My quite niche open source project broke this threshold last year, via Github sponsorships. Of course, I put a lot of time into it, so it's not "passive income" or even "market rate income", but still, without these sponsorships I wouldn't be able to work on it so much.

    The project is Laminar, a UI library for Scala.js https://laminar.dev

  • turbine

    Purely functional frontend framework for building web applications (by funkia)

  • precept

    A declarative programming framework

  • wick

    Functional, reactive WebAssembly with a twist

    • Project mention: Was Rust Worth It? | news.ycombinator.com | 2023-10-25

    Good lord, that is an INCREDIBLE number of lints to disable, and for... what? If you have to disable lints telling you about things like unused/dead code, intentional validation of the language's conventional style, unused/unnecessary allocations, useless/trivial type casts, ... then I really wonder what kind of code is actually being written.
