NAME

       Dancer::Serializer - serializer wrapper for Dancer

DESCRIPTION

       This module is the wrapper that provides support for different serializers.

USAGE

   Configuration
       The serializer configuration variable tells Dancer which serializer to use to deserialize request and serialize response.

       You change it either in your config.yml file:

	   serializer: "YAML"

       Or in the application code:

	   # setting JSON as the default serializer
	   set serializer => 'JSON';

       In your routes you can access parameters just like any route.

       When in a route you return a Perl data structure, it will be serialized automatically to the respective serialized engine (for instance,
       "JSON").

       For "PUT" and "POST" methods you can access the "request-"body> as a string, and you can unserialize it, if you really need. If your
       content type is recognized by the serializer, "request-"body> will be unserialized automatically, and it will be available as a standard
       parameter.

       For instance, if you call

	curl -X POST -H 'Content-Type: application/json -d "{'id':'bar'}" /foo

       your "foo" route can do something like:

	 post "/foo" => {
	    my $id = param('id'); # gets "bar"
	    #  ...
	 }

NAME

       Dancer::Plugin::REST - A plugin for writing RESTful apps with Dancer

SYNOPSYS

	   package MyWebService;

	   use Dancer;
	   use Dancer::Plugin::REST;

	   prepare_serializer_for_format;

	   get '/user/:id.:format' => sub {
	       User->find(params->{id});
	   };

	   # curl http://mywebservice/user/42.json
	   { "id": 42, "name": "John Foo", email: "john.foo@example.com"}

	   # curl http://mywebservice/user/42.yml
	   --
	   id: 42
	   name: "John Foo"
	   email: "john.foo@example.com"

DESCRIPTION

       This plugin helps you write a RESTful webservice with Dancer.

KEYWORDS

   prepare_serializer_for_format
       When this pragma is used, a before filter is set by the plugin to automatically change the serializer when a format is detected in the URI.

       That means that each route you define with a :format token will trigger a serializer definition, if the format is known.

       This lets you define all the REST actions you like as regular Dancer route handlers, without explicitly handling the outgoing data format.

   resource
       This keyword lets you declare a resource your application will handle.

	   resource user =>
	       get    => sub { # return user where id = params->{id}   },
	       create => sub { # create a new user with params->{user} },
	       delete => sub { # delete user where id = params->{id}   },
	       update => sub { # update user with params->{user}       };

	   # this defines the following routes:
	   # GET /user/:id
	   # GET /user/:id.:format
	   # POST /user
	   # POST /user.:format
	   # DELETE /user/:id
	   # DELETE /user/:id.:format
	   # PUT /user/:id
	   # PUT /user/:id.:format

   helpers
       Some helpers are available. This helper will set an appropriate HTTP status for you.

       status_ok

	   status_ok({users => {...}});

       Set the HTTP status to 200

       status_created

	   status_created({users => {...}});

       Set the HTTP status to 201

       status_accepted

	   status_accepted({users => {...}});

       Set the HTTP status to 202

       status_bad_request

	   status_bad_request("user foo can't be found");

       Set the HTTP status to 400. This function as for argument a scalar that will be used under the key error.

       status_not_found

	   status_not_found("users doesn't exists");

       Set the HTTP status to 404. This function as for argument a scalar that will be used under the key error.
