Messages

First let's create the messages we need for fetching players. Add a new import and message to src/Msgs.elm

module Msgs exposing (..)

import Models exposing (Player)
import RemoteData exposing (WebData)


type Msg
    = OnFetchPlayers (WebData (List Player))

OnFetchPlayers will be called when we get the response from the server. This message will carry a WebData (List Player).

WebData is a type that provides four constructors: NotAsked, Loading, Success and Failure. These four possible constructors describe all states in which an HTTP resource could be. Read more about this here.
