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 => {...}});

    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
