The Elm Architecture 🍵

See original GitHub issue

Maybe it would be better if effects shouldn’t be called directly by user but go along with result of updating model as a second element in an array or some other structure and that second element should be handled by runtime so it will be look more like TEA:

update : Msg -> Model -> (Model, Cmd Msg)
update msg model =
  case msg of
    MorePlease ->
      (model, getRandomGif model.topic)

    NewGif (Ok newUrl) ->
      ( { model | gifUrl = newUrl }, Cmd.none)

    NewGif (Err _) ->
      (model, Cmd.none)

I agree that the example now seems a bit more complex. Maybe all we need to do is state in the docs that the effects do not cause a re-render to occur. Essentially, that is the only difference currently between effects and reducers.
