What is the correct way of initializing an elm application

Question

The documentation for Elm\'s Random module states:

A good way to get an unexpected seed is to use the current time. http://package.elm-

Answer 1

Just an update for people who got here from Google like I did: the recommended way to do this now is with flags instead of ports. The code in the other answers will not even compile now.

Elm

type alias Model = {
  mySeed : String
}

type alias Flags = {
  myRandomValue : String
}

init : Flags -> ( Model, Cmd Msg )
init flags =
  {
    mySeed = flags.myRandomValue
  }

...

main : Program Flags Model Msg
main = programWithFlags
  {
    view = view,
    init = init,
    update = update
  }
