NAME

       Mojolicious::Plugin::OpenAPI - OpenAPI / Swagger plugin for Mojolicious

SYNOPSIS

         # It is recommended to use Mojolicious::Plugin::OpenAPI with a "full app".
         # See the links after this example for more information.
         use Mojolicious::Lite;

         # Because the route name "echo" matches the "x-mojo-name", this route
         # will be moved under "basePath", resulting in "POST /api/echo"
         post "/echo" => sub {

           # Validate input request or return an error document
           my $c = shift->openapi->valid_input or return;

           # Generate some data
           my $data = {body => $c->req->json};

           # Validate the output response and render it to the user agent
           # using a custom "openapi" handler.
           $c->render(openapi => $data);
         }, "echo";

         # Load specification and start web server
         plugin OpenAPI => {url => "data:///swagger.yaml"};
         app->start;

       See Mojolicious::Plugin::OpenAPI::Guides::OpenAPIv2 or
       Mojolicious::Plugin::OpenAPI::Guides::OpenAPIv3 for more in depth information about how to
       use Mojolicious::Plugin::OpenAPI with a "full app".  Even with a "lite app" it can be very
       useful to read those guides.

       Looking at the documentation for "x-mojo-to" in
       Mojolicious::Plugin::OpenAPI::Guides::OpenAPIv2 can be especially useful. (The logic is
       the same for OpenAPIv2 and OpenAPIv3)

DESCRIPTION

       Mojolicious::Plugin::OpenAPI is Mojolicious::Plugin that add routes and input/output
       validation to your Mojolicious application based on a OpenAPI (Swagger) specification.
       This plugin supports both version 2.0 and 3.x, though 3.x might have some missing
       features.

       Have a look at the "SEE ALSO" for references to plugins and other useful documentation.

       Please report in issues <https://github.com/jhthorsen/json-validator/issues> or open pull
       requests to enhance the 3.0 support.

HELPERS

   openapi.spec
         $hash = $c->openapi->spec($json_pointer)
         $hash = $c->openapi->spec("/info/title")
         $hash = $c->openapi->spec;

       Returns the OpenAPI specification. A JSON Pointer can be used to extract a given section
       of the specification. The default value of $json_pointer will be relative to the current
       operation. Example:

         {
           "paths": {
             "/pets": {
               "get": {
                 // This datastructure is returned by default
               }
             }
           }
         }

   openapi.validate
         @errors = $c->openapi->validate;

       Used to validate a request. @errors holds a list of JSON::Validator::Error objects or
       empty list on valid input.

       Note that this helper is only for customization. You probably want "openapi.valid_input"
       in most cases.

   openapi.valid_input
         $c = $c->openapi->valid_input;

       Returns the Mojolicious::Controller object if the input is valid or automatically render
       an error document if not and return false. See "SYNOPSIS" for example usage.

HOOKS

       Mojolicious::Plugin::OpenAPI will emit the following hooks on the application object.

   openapi_routes_added
       Emitted after all routes have been added by this plugin.

         $app->hook(openapi_routes_added => sub {
           my ($openapi, $routes) = @_;

           for my $route (@$routes) {
             ...
           }
         });

       This hook is EXPERIMENTAL and subject for change.

RENDERER

       This plugin register a new handler called "openapi". The special thing about this handler
       is that it will validate the data before sending it back to the user agent. Examples:

         $c->render(json => {foo => 123});    # without validation
         $c->render(openapi => {foo => 123}); # with validation

       This handler will also use "renderer" to format the output data. The code below shows the
       default "renderer" which generates JSON data:

         $app->plugin(
           OpenAPI => {
             renderer => sub {
               my ($c, $data) = @_;
               return Mojo::JSON::encode_json($data);
             }
           }
         );

ATTRIBUTES

   route
         $route = $openapi->route;

       The parent Mojolicious::Routes::Route object for all the OpenAPI endpoints.

   validator
         $jv = $openapi->validator;

       Holds either a JSON::Validator::Schema::OpenAPIv2 or a JSON::Validator::Schema::OpenAPIv3
       object.

METHODS

   register
         $openapi = $openapi->register($app, \%config);
         $openapi = $app->plugin(OpenAPI => \%config);

       Loads the OpenAPI specification, validates it and add routes to $app. It will also set up
       "HELPERS" and adds a before_render hook for auto-rendering of error documents. The return
       value is the object instance, which allow you to access the "ATTRIBUTES" after you load
       the plugin.

       %config can have:

       coerce

       See "coerce" in JSON::Validator for possible values that "coerce" can take.

       Default: booleans,numbers,strings

       The default value will include "defaults" in the future, once that is stable enough.

       default_response

       Instructions for "add_default_response_schema" in JSON::Validator::Schema::OpenAPIv2.
       (Also used for OpenAPIv3)

       format

       Set this to a default list of file extensions that your API accepts. This value can be
       overwritten by "x-mojo-to" in Mojolicious::Plugin::OpenAPI::Guides::OpenAPIv2.

       This config parameter is EXPERIMENTAL and subject for change.

       log_level

       "log_level" is used when logging invalid request/response error messages.

       Default: "warn".

       op_spec_to_route

       "op_spec_to_route" can be provided if you want to add route definitions without using
       "x-mojo-to". Example:

         $app->plugin(OpenAPI => {op_spec_to_route => sub {
           my ($plugin, $op_spec, $route) = @_;

           # Here are two ways to customize where to dispatch the request
           $route->to(cb => sub { shift->render(openapi => ...) });
           $route->to(ucfirst "$op_spec->{operationId}#handle_request");
         }});

       This feature is EXPERIMENTAL and might be altered and/or removed.

       plugins

       A list of OpenAPI classes to extend the functionality. Default is:
       Mojolicious::Plugin::OpenAPI::Cors, Mojolicious::Plugin::OpenAPI::SpecRenderer and
       Mojolicious::Plugin::OpenAPI::Security.

         $app->plugin(OpenAPI => {plugins => [qw(+Cors +SpecRenderer +Security)]});

       You can load your own plugins by doing:

         $app->plugin(OpenAPI => {plugins => [qw(+SpecRenderer My::Cool::OpenAPI::Plugin)]});

       renderer

       See "RENDERER".

       route

       "route" can be specified in case you want to have a protected API. Example:

         $app->plugin(OpenAPI => {
           route => $app->routes->under("/api")->to("user#auth"),
           url   => $app->home->rel_file("cool.api"),
         });

       skip_validating_specification

       Used to prevent calling "errors" in JSON::Validator::Schema::OpenAPIv2 for the
       specification.

       spec_route_name

       Name of the route that handles the "basePath" part of the specification and serves the
       specification. Defaults to "x-mojo-name" in the specification at the top level.

       spec, url

       See "schema" in JSON::Validator for the different "url" formats that is accepted.

       "spec" is an alias for "url", which might make more sense if your specification is written
       in perl, instead of JSON or YAML.

       Here are some common uses:

         $app->plugin(OpenAPI => {url  => $app->home->rel_file('openapi.yaml'));
         $app->plugin(OpenAPI => {url  => 'https://example.com/swagger.json'});
         $app->plugin(OpenAPI => {spec => JSON::Validator::Schema::OpenAPIv3->new(...)});
         $app->plugin(OpenAPI => {spec => {swagger => "2.0", paths => {...}, ...}});

       version_from_class

       Can be used to overridden "/info/version" in the API specification, from the return value
       from the "VERSION()" method in "version_from_class".

       Defaults to the current $app. This can be disabled by setting the "version_from_class" to
       zero (0).
