Transformers

Elixir library for transforming keys and values in nested maps or list of maps.

Installation

Package can be installed by adding transformers to your list of dependencies in mix.exs:

def deps do
  [
    {:transformers, "~> 0.1.0"}
  ]
end

Examples

Take a nested map or list of maps:

iex> data = %{
  "nested_map" => [
    %{"some_map" => "One"},
    %{"another_map" => "Two"},
    ["Three"]
  ]
}

Camelize keys:

iex> Transformers.transform_keys(data, &Macro.camelize/1)
%{
  "NestedMap" => [
    %{"SomeMap" => "One"},
    %{"AnotherMap" => "Two"},
    ["Three"]
  ]
}

Upcase values:

iex> Transformers.transform_values(data, &String.upcase/1)
%{
  "nested_map" => [
    %{"some_map" => "ONE"},
    %{"another_map" => "TWO"},
    ["THREE"]
  ]
}
