      version: "1.0"
    basePath: /api
    paths:
      /welcome:
        get:
          operationId: my_controller
          responses:
            200:
              description: success

Then on the terminal run:

    perl my_app.pl

MIGRATING FROM DANCER1

If you've been using Dancer1 before you might know Dancer::Plugin::Swagger. Please note that that module's workflow is completely different! It is about creating the spec from the app. The module described in this text is about reading the spec and creating parts of the app for you.

DEBUGGING

To see some more debug messages on STDERR set environment variable SWAGGER2_DEBUG to a true value.

METHODS

swagger2( url => $url, ... )

Import routes from Swagger file. Named arguments:

  • url: URL to passed to Swagger2 module

  • controller_factory: custom callback generator/finder that returns callbacks to routes

  • validate_spec: boolish value (default: true) telling if Swagger2 file shall be validated by official Swagger specification

  • validate_requests: boolish value (default: same as validate_spec) telling if HTTP requests shall be validated by loaded specification (needs validate_spec to be true)

  • validate_responses: boolish value (default: same as validate_spec) telling if HTTP responses shall be validated by loaded specification (needs validate_spec to be true)

default_controller_factory

Default method for finding a callback for a given operationId. Can be overriden by the controller_factory argument to swagger2 or config option.

The default uses the controller argument/config option or the name of the app (possibly with ::Controller appended). If the operationId looks like a Perl module the module name is tried under the namespace mentioned above and as a top level module name.

The module warns as long as controller modules or methods can't be found and returns a coderef on the first match.
