NAME

Dancer2::Core::Role::Serializer - Role for Serializer engines

VERSION

version 1.1.0

DESCRIPTION

Any class that consumes this role will be able to be used as a serializer under Dancer2.

In order to implement this role, the consumer must implement the methods serialize and deserialize, and should define the content_type attribute value.

ATTRIBUTES

content_type

The content type of the object after being serialized. For example, a JSON serializer would have a application/json content type defined.

METHODS

serialize($content, [\%options])

The serialize method need to be implemented by the consumer. It receives the serializer class object and a reference to the object to be serialized. Should return the object after being serialized, in the content type defined by the content_type attribute.

A third optional argument is a hash reference of options to the serializer.

The serialize method must return bytes and therefore has to handle any encoding.

deserialize($content, [\%options])

The inverse method of serialize. Receives the serializer class object and a string that should be deserialized. The method should return a reference to the deserialized Perl data structure.

A third optional argument is a hash reference of options to the serializer.

The deserialize method receives encoded bytes and must therefore handle any decoding required.

CONFIGURATION

The serializer configuration variable tells Dancer2 which engine to use.

You can change it either in your config.yml file:

#Set JSON engine
serializer: "JSON"

# Prettify JSON output
engines:
  serializer:
    JSON:
      pretty: 1

To know which engines are availables please see "Serializers" in Dancer2::Manual
