elm-media-type

elm-media-type lets you parse and handle media types like text/html; charset=UTF-8 and application/javascript in Elm.

Here is an example of how it works:

MediaType.fromString "application/javascript"
  == Just
      { parameters = Dict.fromList []
      , registrationTree = Nothing
      , subtype = "javascript"
      , suffix = Nothing
      , type_ = Application
      }
