Swagger Documentation Provider for Laminas API Tools

Introduction

This module provides Laminas API Tools the ability to show API documentation through a Swagger UI.

The Swagger UI is immediately accessible after enabling this module at the URI path /api-tools/swagger.

In addition to providing the HTML UI, this module also plugs into the main Laminas API Tools documentation resource (at the path /api-tools/documentation) in order to allow returning a documentation payload in the application/vnd.swagger+json media type; this resource is what feeds the Swagger UI. You can access this representation by passing the media type application/vnd.swagger+json for the Accept header via the path /api-tools/documentation/:module/:service.

Requirements

Please see the composer.json file.

Installation

Run the following composer command:

$ composer require laminas-api-tools/api-tools-documentation-swagger

Alternately, manually add the following to your composer.json, in the require section:

"require": {
    "laminas-api-tools/api-tools-documentation-swagger": "^1.2"
}

And then run composer update to ensure the module is installed.

Finally, add the module name to your project's config/application.config.php under the modules key:

return [
    /* ... */
    'modules' => [
        /* ... */
        'Laminas\ApiTools\Documentation\Swagger',
    ],
    /* ... */
];

laminas-component-installer

If you use laminas-component-installer, that plugin will install api-tools-documentation-swagger as a module for you.

Routes

Assets: /api-tools-documentation-swagger/

Various CSS, images, and JavaScript libraries required to deliver the Swagger UI client application.

Configuration

System Configuration

The following is required to ensure the module works within a Laminas and/or Laminas API Tools-enabled application:

Laminas Events

Listeners

Laminas\ApiTools\Documentation\Swagger\Module

This listener is attached to the MvcEvent::EVENT_RENDER event at priority 100. Its purpose is to conditionally attach a view strategy to the view system in cases where the controller response is a Laminas\ApiTools\Documentation\Swagger\ViewModel view model (likely selected as the content-negotiated view model based off of Accept media types).

Laminas Services

View Models

Laminas\ApiTools\Documentation\Swagger\ViewModel

This view model is responsible for translating the available Laminas\ApiTools\Documentation models into Swagger-specific models, and further casting them to arrays for later rendering as JSON.

Images in the documentation, and the API Tools Admin UI itself, still refer to Apigility. This is due to the fact that we only recently transitioned the project to its new home in the Laminas API Tools. Rest assured that the functionality remains the same.
