Hi,

I am confused. I have code like this:

BannersView.elm:

> module Banners.View exposing (view)  
> – …

Main.elm:

> – …  
> import Banners.View  
> – …  
> Banners.View.view …

This produces the following error at compile time:

> I cannot find module ‘Banners.View’.
> 
> Module ‘ZKMain’ is trying to import it.
> 
> Potential problems could be:
> 
> - Misspelled the module name
> - Need to add a source directory or new dependency to elm-package.json

However, if I remove the dot from the module name (i.e. name it BannersView), everything compiles fine.

Is there some trick in elm-package.json to make the name with a dot work correctly?

Best,  
Michal

In Elm, the module name needs to be the same as the file name, and the prefixes need to be the same as the path of the file within a source directory.

If you want your module to be named `Banners.View`, you’ll need to name the file `View.elm` and place it in a folder named `Banners` within a source directory:

```auto
   .
   | - src
   | | - Banners
   | | | - View.elm
   | | 
   | | - Main.elm
   |
   | - elm-package.json

```

Hi,

Thanks! I expected something of the kind, but couldn’t find any documentation.

So it won’t work even if I name the file Banners.View.elm?

I’ll just keep the name without the dot, then, because the file resides in directory called Pages which makes more sense to me 🙂

Best,  
Michal
