This plugin helps you write a RESTful webservice with Dancer.
KEYWORDS
prepare_serializer_for_format
When this pragam 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 defintion, if the format is known.
This lets you define all the REST action you like aas regular Dancer route handlers, without taking care of 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/create
# POST /user/create.:format
# DELETE /user/:id
# DELETE /user/:id.:format
# PUT /user/:id
# PUT /user/:id.:formathelpers
