Transforms the keys of an HTTP response to the case requested by the client.

A client can request what case the keys are formatted in by passing the case as a header in the request. By default the header key is Accent. If the client does not request a case or requests an unsupported case then no conversion will happen. By default the supported cases are camel, pascal and snake.

Options

• :header - the HTTP header used to determine the case to convert the response body to before sending the response (default: Accent)
• :json_encoder - module used to encode JSON. The module is expected to define a encode!/1 function for encoding the response body as JSON. (required)
• :json_decoder - module used to decode JSON. The module is expected to define a decode!/1 function for decoding JSON into a map. (required)
• :supported_cases - map that defines what cases a client can request. By default camel, pascal and snake are supported.

Examples

plug Accent.Plug.Response, header: "x-accent",
                           supported_cases: %{"pascal" => Accent.Transformer.PascalCase},
                           json_encoder: Poison,
                           json_decoder: Poison
