reflex-platform

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 an

Reflex Platform supports native mobile builds to some extent: * https://github.com/ElvishJerricco/reflex-project-skeleton * https://github.com/reflex-frp/reflex-platform/blob/develop/d...

Haskell on web, Android, iOS, desktop (and shared code with the server of course) with https://github.com/reflex-frp/reflex-platform It's pretty hard to beat the productivity of one codebase for every platform with a powerful type system catching errors across every part of system.

If you are interested in Haskell I'd suggest starting with Elm (quite easy to get started) and then move into GHCJS by trying https://haskell-miso.org/ ... and if you will still be motivated try http://docs.reflex-frp.org .. and eventually you use Haskell to write both backend and frontend: https://github.com/reflex-frp/reflex-platform/blob/develop/d...

Haskell + Nix is the best environment I've ever used for any development. My go-to project manager is this script in the reflex-platform, which is a bit poorly named (it will change eventually), because it's actually an environment for doing general cross-platform full stack Haskell development: https://github.com/reflex-frp/reflex-platform/blob/develop/p... The learning curve is definitely, shamelessly high. We've been slowly polishing it to make it easy for complete beginners to fully up-to-speed on a project in minutes, but it's a lot of work that happens mostly on weekends. Watch this space!

My shop specializes in multiplatform FRP applications via the reflex haskell library [0]. After many years of wrangling FRP my biggest learned lesson is certainly this: not everything is a stream! You need to be able to mix streams (also called events), which embody push semantics and behaviors (things you can sample), which embody pull semantics. This is important for performance and for the structure of large applications. Coming up with a set of primitives to efficiently combine events and behaviors in expressive ways is really difficult but worth it. [0] https://github.com/reflex-frp/reflex-platform

Has anyone tried Reflex? Really interesting concept in Haskell + GHCJS https://github.com/ryantrinkle/try-reflex I liked Elm but I felt the language was a bit limited coming from Haskell, ex no type classes so you have List.map, Signal.map, Set.map, etc Overall Elm is great in terms of tooling, setup, error messages, performance, js interop though

Don't forget about reflex[0], you can try it here[1]. I also use purescript[2] with purescript-halogen[3] as does slamdata[4]. There's also a video on Purescript halogen[5] that's very interesting. Purescript is great because the JavaScript it generates is so readable, that if you really need to you can understand the output and make micro-optimizations. 0: https://github.com/ryantrinkle/reflex 1: https://github.com/ryantrinkle/try-reflex 2: http://purescript.org/ 3: https://github.com/slamdata/purescript-halogen 4: http://slamdata.com/ 5: https://www.youtube.com/watch?v=AbDX-wRigAo

> I'm hoping that we can find a GHCJS-based FRP solution at some point soon. Have you tried Reflex (also there is a try-reflex[1])? Purescript generates really concise javascript code, have you checked out Thermite[2]? 0: https://github.com/ryantrinkle/reflex 1: https://github.com/ryantrinkle/try-reflex 2: https://github.com/paf31/purescript-thermite

Oh, there is the try-reflex readme. https://github.com/ryantrinkle/try-reflex/blob/master/README...
