DESCRIPTION

37       This plugin helps you write a RESTful webservice with Dancer2.
38

CONFIGURATION

40   serializers
41       The default format serializer hash which maps a given ":format" to a
42       "Dancer2::Serializer::*" serializer. Unless overriden in the
43       configuration, it defaults to:
44
45           serializers:
46             json: JSON
47             yml:  YAML
48             dump: Dumper
49

KEYWORDS

51   prepare_serializer_for_format
52       When this pragma is used, a before filter is set by the plugin to
53       automatically change the serializer when a format is detected in the
54       URI.
55
56       That means that each route you define with a :format param or captures
57       token will trigger a serializer definition, if the format is known.
58
59       This lets you define all the REST actions you like as regular Dancer2
60       route handlers, without explicitly handling the outgoing data format.
61
62       Regexp routes will use the file-extension from captures->{'format'} to
63       determine the serialization format.
64
65   resource
66       This keyword lets you declare a resource your application will handle.
67
68           resource user =>
69               get    => sub { # return user where id = params->{id}   },
70               create => sub { # create a new user with params->{user} },
71               delete => sub { # delete user where id = params->{id}   },
72               update => sub { # update user with params->{user}       };
73
74           # this defines the following routes:
75           # GET /user/:id
76           # GET /user/:id.:format
77           # POST /user
78           # POST /user.:format
79           # DELETE /user/:id
80           # DELETE /user/:id.:format
81           # PUT /user/:id
82           # PUT /user/:id.:format

152           status_504    status_gateway_timeout
153           status_505    status_http_version_not_supported
154           status_506    status_variant_also_negotiates

161           status_599    status_network_connect_timeout_error
162
163       All 1xx, 2xx and 3xx status helpers will set the response status to the
164       right value and serves its argument as the response, serialized.
165
166           status_ok({users => {...}});
167           # set status to 200, serves the serialized format of { users => {... } }
168
169           status_200({users => {...}});
170           # ditto
171
172           status_created({users => {...}});
173           # set status to 201, serves the serialized format of { users => {... } }
174
175       For error statuses ( 4xx and 5xx ), there is an additional dash of
176       syntaxic sugar: if the argument is a simple string, it'll be converted
177       to "{ error =" $error }>.
178
179           status_not_found({ error => "file $name not found" } );
180           # send 404 with serialization of { error => "file blah not found" }
181
182           status_not_found("file $name not found");
183           # ditto
