Elm support

[ArthurFleischman]

I tried this once, and besides some tweaks here an there is viable since the language generates a SPA by itself, Im talking about using Elm language with tauri to generate a desktop reactive app. The idea came when I was(and still am) using Yew + tauri for a freelance desktop app, since yew has a very similar routine of building pages(creation, event handling, render) as elm(and I think inspired on) I tried for once to mix these to very different universes, and worked very well, is a great DX and elm reactor is awesome like mamas heart, I recommend you trying it. So I came to my mind, why not give support? not that alm really needs much since it has backward compatibility with JS so the invoke still viable, but add it to the create-tauri-app command line.

import Browser
import Html exposing (Html, button, div, text)
import Html.Events exposing (onClick)



-- MAIN


main =
  Browser.sandbox { init = init, update = update, view = view }



-- MODEL

type alias Model = Int

init : Model
init =
  0


-- UPDATE

type Msg = Increment | Decrement

update : Msg -> Model -> Model
update msg model =
  case msg of
    Increment ->
      model + 1

    Decrement ->
      model - 1


-- VIEW

view : Model -> Html Msg
view model =
  div []
    [ button [ onClick Decrement ] [ text "-" ]
    , div [] [ text (String.fromInt model) ]
    , button [ onClick Increment ] [ text "+" ]
    ]

Basic example of counter with button

for those whom already used any rust based frontend app, looks alike

but add it to the create-tauri-app command line.

We want to keep create-tauri-app fairly minimal. We made the mistake in its v2 version to add too many templates to it and ended up not being able to maintain them. We do would like to see community template support at some point though, but until them adding templates to https://github.com/tauri-apps/awesome-tauri/ is the way to go. When our new docs go live they will also have a place for community templates :)

Nice! thanks

Supporting other languages than JavaScript is actually the main intention behind the tauri-bindgen project (maintaining all these language bindings manually would be impossible) but adding elm support is a bit trickier (specifically because reactor doesn't let us specify ports in development mode) so elm will likely not be supported first-class for a while.

In the meantime however, there are templates out there (and as @FabianLars said submit your own if you have created one!) that can serve as a starting point for an elm+tauri setup
