elmish VS ionide-vscode-fsharp

For those interested in .NET languages with alternative compilation targets, Elmish (https://elmish.github.io/elmish/) is pretty unique.

We use F# on the front end (instead of TS), and thanks to the Fable compiler (which transpiles F# to JS, Python, Dart, PHP and Rust), most of the benefits of an Elm-style model in the UI can be ported to all sorts of different outputs languages. The rust target is in beta, but its promising because the WASM bundle size stands to be dramatically lower.

While the default is reactivity library for Elmish is React, you can swap in Avalonia/FuncUI (https://github.com/fsprojects/Avalonia.FuncUI) pretty easily as well.

Naturally I’d recommend using a better language such as ReScript or Elm or PureScript or F#‘s Fable + Elmish, but “React” is the king right now and people perceive TypeScript as “less risky” for jobs/hiring, so here we are.

Since you're familiar with React + Reframe, you can try Elmish! You can use F# to write [Elmish](https://elmish.github.io/elmish/) apps. It takes the Elm approach to building apps.

Try F# with Elmish.

I never tried Elm directly, but I have used the F# equivalent Elmish - super productive idea.

You can also get nested templates, bind inputs, and radios for example by the way don't be scared by the mutable keyword right there is just to show a brief example in a normal situation you would likely be using Elmish

Comet promotes a variation of the Model-View-Update pattern popularized by The Elm Architecture, Elmish, Fabulous and others. The major parts of MVU are:

I'd love to see something similar to Microsoft's Ionide project or for JetBrains to invest in IDE support.

It pains me to admit it because I really like F# but, with due respect to the developers, Ionide and its related projects are the most unstable toolchain I've ever used.

Spend half a day reloading the editor because the extension keeps hanging on non-trivial MSBuild only to discover that the formatter has truncated in half one of the files you worked on due to a soundness bug. (OCaml's editor support, in contrast, is quite stable.)

Rider is the best editing experience I've had with F#, by far.

I know it's a recurring topic but it's reaching a high level of pain *again* (see NET SDK 6.0.400 and 7.0.100 previews don't currently work with Ionide).

I don't disagree but it owes a lot of that to OCaml. That said, since we're talking about C#, F# and VS Code I'm gonna talk about a pet peeve I have. If you open a C# project in VS Code when the "Ionide" (basically the F# plugin for Code) is installed then Ionide thinks it's a F# project and will open some F# stuff after a few seconds (or prompt you to setup some F# stuff in its gitignore). The root cause has been identified (plugin activates when it sees a ".sln" file), a PR have been opened and rejected with no mention as to why (https://github.com/ionide/ionide-vscode-fsharp/pull/1401) and the developers behind it are frustratingly non-communicative about it, closing issues about it (https://github.com/ionide/ionide-vscode-fsharp/issues/1701). Usual rules about OSS maintainers apply, they don't technically owe us users anything ... but man it feels like we're being trolled by now :D

F# doesn't have a hard dependency on vscode. Resources from MS will obviously encourage using MS tooling, but ionide [1] is really good. The lsp+neovim workflow is not as good but getting better.

Important thread about this: https://github.com/ionide/ionide-vscode-fsharp/issues/1693

Perf Avore was developed on VSCode using the ionide plugin and dotnet cli.

I was on .Net 5 but same issue on 6. I tried the fix here- setting FSharp.dotnetRoot explicitly in settings.json and so far it seems better.

Make sure to keep an eye on this MR for that very capability :)
