In Elm module names and file names should start from a capital letter. Just rename your module to Hello and your file to Hello.elm.

Module1.OneMsg is a type. Html.map expects a function as its first parameter. The way you typically bubble up messages would be something like this (in Module2):

Elm is a pure language where side effects are relegated to the framework. Calling the update function does not actually perform any work itself. It simply returns a value that can be handed off to the Elm framework directing it to interact with the outside world. That means when you call update from within the page function and discard the result, nothing happens.

One thing that can cause confusion is that Debug.log actually does get called and prints to the console, which violates the aforementioned purity of the language. It's just a magic function which exists only for debugging so hopefully it doesn't cause too much confusion.

You should instead be handling the RemoteData.Success case in the update function after parsing the route in the OnLocationChange case and returning a result which includes the getArticles result Cmd.

If this is inside the file List.elm in your Players folder, maybe you should change it to a lowercase list. That function is defined in that same file.
