# Casefy

## Usage

# camel_case

```elixir
  Casefy.camel_case(%{camel_case: 1, nested_case: %{ another_case: 1 }}) 
  # returns  %{ "camelCase" => 1, "nestedCase" => %{ "anotherCase" => 1 } }
```

# snake_case

```elixir
  Casefy.snake_case(%{snakeCase: 1, nestedCase: %{anotherCase: 1}}) 
  # returns  %{ "snake_case" => 1, "nested_case" => %{ "another_case" => 1 } }
```

# Plug

On your Router, use:

```elixir
  pipeline :api do
    plug :accepts, ["json"]
    ...
    plug Casefy.Plug, fields: [:query_params, :params, :body_params] # parses all camelCase input to snake_case inside your controller
  end
```

# View
On your View, use:
```elixir
  use Casefy.View, parse: :camel_case

  def render("index.json", %{snake_case: snake_case}) do
    renderer(%{data: snake_case}) # by default, applies deep camel_case parsing
  end
```

Or directly on your Controller, use:
```elixir
  use Casefy.View, parse: :camel_case

  renderer(render(MyView, "index.json", %{snakeCase: %{anotherNested: %{caseFy: 1}}}), :snake_case)
  # returns %{ "snake_case" => %{ "another_nested" => %{ "case_fy: 1 } }}
```
