NAME

       Dancer::Serializer::Mutable - Serialize and deserialize content using the appropriate HTTP
       header

VERSION

       version 1.3521

SYNOPSIS

           # in config.yml
           serializer: Mutable

           # in the app
           put '/something' => sub {
               # deserialized from request
               my $name = param( 'name' );

               ...

               # will be serialized to the most
               # fitting format
               return { message => "user $name added" };
           };

DESCRIPTION

       This serializer will try find the best (de)serializer for a given request.  For this, it
       will pick the first content type found from the following list and use its related
       serializer.

       •   The content_type from the request headers

       •   the content_type parameter from the URL

       •   the accept from the request headers

       •   The default is application/json

       The content-type/serializer mapping that "Dancer::Serializer::Mutable" uses is

           serializer               | content types
           ----------------------------------------------------------
           Dancer::Serializer::YAML | text/x-yaml, text/html
           Dancer::Serializer::XML  | text/xml
           Dancer::Serializer::JSON | text/x-json, application/json

EXPORTABLE FUNCTIONS

   template_or_serialize( $template, $data, $options )
       For instances where you want to render a template for normal browser requests, and return
       serialized content for AJAX calls.

       If the requested content-type is text/html, "template_or_serialize" returns the rendered
       template, else it returns $data unmodified (which will then be serialized as usual).

       "template_or_serialize" is not exported by default.

           use Dancer::Serializer::Mutable qw/ template_or_serialize /;

           get '/greetings' => sub {
               ...;

               return template_or_serialize 'greetings' => {
                   title => $title,
                   name  => $name,
               };
           };

   INTERNAL METHODS
       The following methods are used internally by "Dancer" and are not made accessible via the
       DSL.

   serialize
       Serialize a data structure. The format it is serialized to is determined automatically as
       described above. It can be one of YAML, XML, JSON, defaulting to JSON if there's no clear
       preference from the request.

   deserialize
       Deserialize the provided serialized data to a data structure.  The type of serialization
       format depends on the request's content-type. For now, it can be one of YAML, XML, JSON.

   content_type
       Returns the content-type that was used during the last "serialize" / "deserialize" call.
       WARNING : you must call "serialize" / "deserialize" before calling "content_type".
       Otherwise the return value will be "undef".
