Yii Swagger

OpenAPI Swagger for Yii Framework.

Requirements

• PHP 8.0 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/yii-swagger

Configuration

1. Add route configuration to config/routes.php

use Yiisoft\DataResponse\Middleware\FormatDataResponseAsHtml;
use Yiisoft\DataResponse\Middleware\FormatDataResponseAsJson;
use Yiisoft\Router\Group;
use Yiisoft\Router\Route;
use Yiisoft\Swagger\Middleware\SwaggerUi;
use Yiisoft\Swagger\Action\SwaggerJson;

// Swagger routes
Group::create('/swagger', [
    Route::get('')
        ->middleware(FormatDataResponseAsHtml::class)
        ->action(fn (SwaggerUi $swaggerUi) => $swaggerUi->withJsonUrl('/swagger/json-url')),
    Route::get('/json-url')
        ->middleware(FormatDataResponseAsJson::class)
        ->action(SwaggerJson::class),
]),

2. Add annotations to default API controller

use OpenApi\Annotations as OA;

/**
 * @OA\Info(title="My first API", version="1.0")
 */
class DefaultController {
    // ...
}

and before actions

/**
 * @OA\Get(
 *     path="/api/endpoint",
 *     @OA\Response(response="200", description="Get default action")
 * )
 */
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
    // ...
}

See Swagger-PHP documentation for details on how to annotate your code.

3. Configure SwaggerJson action

For annotations to be registered you need to configure SwaggerJson.

You can use the parameters in config/params.php to configure SwaggerJson:

//...
'yiisoft/yii-swagger' => [
    'annotation-paths' => [
        '@src/Controller' // Directory where annotations are used
    ],
    'cacheTTL' => 60 // Enables caching and sets TTL, "null" value means infinite cache TTL.
],
//...

4. (Optional) Add config for aliases and asset manager

use Yiisoft\Definitions\Reference;
use Yiisoft\Assets\AssetManager;

return [
    //...
    'yiisoft/aliases' => [
        'aliases' => [
            //...
            '@views' => '@root/views',
            '@assets' => '@public/assets',
            '@assetsUrl' => '@baseUrl/assets',
        ],
    ],
    'yiisoft/view' => [
        'basePath' => '@views',
        'defaultParameters' => [
            'assetManager' => Reference::to(AssetManager::class),
        ]
    ],
    //...
];

5. (Optional) Configure SwaggerUi action

You can use the parameters in config/params.php to configure SwaggerUi.

For example, you can enable persisting authorization by setting the persistAuthorization parameter to true.

//...
'yiisoft/yii-swagger' => [
    'ui-params' => [
        'persistAuthorization' => true,
    ],
],
//...

You can find a complete list of parameters by following the link.

6. (Optional) Configure SwaggerService

You can specify options for generation an OpenApi\Annotations\OpenApi instance in config/params.php to configure SwaggerService:

//...
'yiisoft/yii-swagger' => [
    // Default values are specified.
    'open-api-options' => [
        'aliases' => OpenApi\Generator::DEFAULT_ALIASES,
        'namespaces' => OpenApi\Generator::DEFAULT_NAMESPACES,
        'analyser' => null,
        'analysis' => null,
        'processors' => null,
        'logger' => null,
        'validate' => true,
        'version' => OpenApi\Annotations\OpenApi::DEFAULT_VERSION,
    ],
],
//...

For more information about generation an OpenApi\Annotations\OpenApi instance, see the documentation of the zircote/swagger-php package.
