I'm trying to write a MVVM with RxSwift and comparing to what I was used to do in ReactiveCocoa for Objective-C it's been a little hard to write my service in the right way. An exemple is a Login...

I’m starting with RxJava, and I would like to create an observable that can save the last state… In RxSwift, that would be Variable (https://github.com/ReactiveX/RxSwift/blob/master/Documentation...

I have been experimenting with RxJS for two weeks now, and although I love it in principle I just cannot seem to find and implement the correct pattern for managing state. All articles and question...

I need to model following in RAC. I have a tabBarController which will subscribe to a notification signal. Say push notification. Also say currently active view controller may also be want to sub...

From ReactiveX introduction page: It is sometimes called “functional reactive programming” but this is a misnomer. ReactiveX may be functional, and it may be reactive, but “functional reac...

Since sodium has been deprecated by the author I'm trying to port my code to reactive-banana. However, there seem to be some incongruencies between the two that I'm having a hard time overcomming. ...

I'm brand new to Rx and am finding it difficult to find documentation on composing promises such that data from the first promise is passed into the second and so on. Here's three very basic promis...

I am currently trying to observe any changes to a given object including all of it's elements. The following code only fires when an object[x] is updates, but not if individually updating object[x...

Since subjective answers are to be avoided on SO, I'm specifically asking: What are the functional and/or performance differences between these three functional/reactive libraries that would make m...

Here's code that used to work (truncated appropriately I hope) makeNetworkDescription :: forall t . Frameworks t => Parameters -> Moment t () makeNetworkDescription params = do eInput <-...

I'm trying to get into Netwire, I've dug to find documentations, introductions, tutorials and whatnot, but just about every tutorial & existing-code is outdated as to Netwire 5 and uses functio...

I'm getting started with Netwire version 5. I have no problem writing all the wires I want to transform my inputs into my outputs. Now the time has come to write the IO wrapper to tie in my real-...

I am testing with the Netwire haskell library and made it work with a simple time wire: import Control.Wire import Prelude hiding ((.), id) import Control.Monad.IO.Class import Data.Functor.Ident...

I am trying to create a game using Haskell + Netwire 5 (+ SDL). Now I am working on the output part, where I would like to create wires that read in some game state and output the SDL surfaces to b...

Is it safe to trigger the fire action in (addHandler, fire) <- newAddHandler from a different thread from which the reactive-banana graph was compiled?

I have a form, which has many image urls - the back-end persists url strings and the images are uploaded directly to S3. I'd like to use Bacon.js streams to handle disabling/enabling the form's sub...

In reactive-banana, I am trying to run reactimate :: Event (IO ()) -> Moment () with some actions of Arduino in hArduino package, an instance of MonadIO. There seems no function of Arduino a -&g...

I feel like I have a good handle on functional reactive programming (FRP) "in the small", e.g. composing mouse events together into a "drag" event stream or mapping and filtering WebSocket events i...

I want to study FRP in Haskell, but it's a bit difficult to decide on a library to use. Many seem to be dead attempts, some seem to have been resurrected (such as recent activity on Yampa). From wh...

UPDATE: there is a issue in ghcjs: https://github.com/ghcjs/ghcjs/issues/296 i play with ghcjs and sodium but after 3 seconds my application doesn't emit events anymore. a minimal example: a ...

I am currently trying to understand arrows and FRP, and I came upon a question, which I cannot seem to map to FRP, namely how to model a road network. I thought I could model a road network as Arr...

The Mousetrap.js library lets you bind a callback function to keys like so: Mousetrap.bind('space', function, 'keydown'); What's the best way to attach a stream to this without using the Bus of D...

For the task I'm working on, the signal system of the Elm programming language seems to be an appropriate solution. But my pure computational functions are implemented in Haskell. Is there a Haske...

I've read about FRP and was very excited. It looks great, so you can write more high-level code, and everything is more composable, and etc. Then I've tried to rewrite my own little game with a fe...

I seem to be a little bit confused when comparing Clojure's core.async to the so called Reactive Extensions (Rx) and FRP in general. They seem to tackle similar problem of async-hronicity, so I won...
