Does Elmish works on Wasm ?

[PawelStadnicki]

First of all, this is an excellent project! I will work with it in the following weeks and twitt about it. I still don't know too much about Blazor, and when I run Elmish code in Wasm it does not hit the update function. The init() is called that return Cmd.of Msg.Something but update never runs.

If I change the component attribute to FunInteractiveServer it works as expected. Are you seeing the same or I have something wrong on my side?

Thanks in advance

What is the setup of your project? (also maybe trying with FunInteractiveWebAssembly could help) In a plain wasm project (or an interactive auto project) it should work just fine.

If you have code/repo where one can take a look at it would be nice

@PawelStadnicki my simple demo like below is working as expected:

open Microsoft.AspNetCore.Components
open Elmish
open Fun.Blazor

module Counter =
    type Model = { Count: int }

    type Msg =
        | Increase
        | Decrease

    let init () = { Count = 0 }, Cmd.none

    let update msg model =
        match msg with
        | Increase -> { Count = model.Count + 1 }, Cmd.none
        | Decrease -> { Count = model.Count - 1 }, Cmd.none

    let view (model: Model) (dispatch: Msg -> unit) = div {
        p { $"Count = {model.Count}" }
        button {
            onclick (fun _ -> dispatch Increase)
            "Increase"
        }
    }

[<Route "/counter">]
// [<FunInteractiveAuto>]
[<FunInteractiveWebAssembly>]
type Counter() =
    inherit FunComponent()
    override _.Render() = html.elmish (Counter.init, Counter.update, Counter.view)

Pls provide your code, so we can investigate it.
