DESCRIPTION

• The content_type from the request headers
• the accept from the request headers
• The default is application/json

The content-type/serializer mapping that "Dancer2::Serializer::Mutable" uses is

    serializer                  | content types
    ----------------------------------------------------------
    Dancer2::Serializer::YAML   | text/x-yaml, text/html
    Dancer2::Serializer::Dumper | text/x-data-dumper
    Dancer2::Serializer::JSON   | text/x-json, application/json

A different mapping can be provided via the config file. For example, the default mapping would be configured as

    engines:
        serializer:
            Mutable:
                mapping:
                    'text/x-yaml'        : YAML
                    'text/html'          : YAML
                    'text/x-data-dumper' : Dumper
                    'text/x-json'        : JSON
                    'application/json'   : JSON

The keys of the mapping are the content-types to serialize, and the values the serializers to use. Serialization for "YAML", "Dumper" and "JSON" are done using internal Dancer mechanisms. Any other serializer will be taken to be as Dancer2 serialization class (minus the "Dancer2::Serializer::" prefix) and an instance of it will be used to serialize/deserialize data. For example, adding Dancer2::Serializer::XML to the mapping would be:

    engines:
        serializer:
            Mutable:
                mapping:
                    'text/x-yaml'        : YAML
                    'text/html'          : YAML
                    'text/x-data-dumper' : Dumper
                    'text/x-json'        : JSON
                    'text/xml'           : XML
