This package makes it easy to make your project's Swagger (OpenAPI v3 JSON or YAML) file accessible in a Swagger UI right in your Laravel application.

The Swagger UI will automatically use your current project environment. It will set your api's base url to the active base url. Possible oauth2 configuration, such as urls and client-id/client-secret, can also be injected in Swagger UI via the configuration file.

## Installation

You can install the package via composer:

```bash
composer require wotz/laravel-swagger-ui
```

After installing Laravel Swagger UI, publish its service provider and configuration file using the `swagger-ui:install` Artisan command.

```bash
php artisan swagger-ui:install
```

## Usage

### Customize authentication and authorization

The Swagger UI is exposed at `/swagger`. By default, you will only be able to access it in the local environment. Within your `app/Providers/SwaggerUiServiceProvider.php` file, there is a `gate` method. This authorization gate controls access to Swagger UI in non-local environments. You can modify this gate as needed to restrict access to your Swagger UI and Swagger (OpenAPI v3) file:

```php
/**
 * Register the Swagger UI gate.
 *
 * This gate determines who can access Swagger UI in non-local environments.
 *
 * @return void
 */
protected function gate()
{
    Gate::define('viewSwaggerUI', function ($user = null) {
        return in_array(optional($user)->email, [
            //
        ]);
    });
}
```

### Customize locations of Swagger (OpenAPI v3) files

In the published `config/swagger-ui.php` file, you edit the path to the Swagger UI and the location of the Swagger (OpenAPI v3) file. By default, the package expects to find the OpenAPI file in 'resources/swagger' directory. You can also provide an url if the OpenAPI file is not present in the Laravel project itself.
This is also where you can define multiple versions for the same api.

```php
// in config/swagger-ui.php

return [
    // ...

'path' => 'swagger',

'versions' => [
        'v1' => resource_path('swagger/openapi.json')
    ],

// ...
];
```

### Customize modifications to Swagger (OpenAPI v3) files and SwaggerUI

By default the package will customize the server url and the oauth urls in the OpenAPI file to the base url of the Laravel application. This can be disabled in the config.

```php
// in config/swagger-ui.php

return [
    // ...

'modify_file' => true,

// ...
];
```

You can also set what variables that should be customizable for the server url in Swagger UI. Variable must be present with the same key (case-sensitive) in the url surrounded by curly brackets.

```php
// in config/swagger-ui.php

return [
    // ...

'server_url' => 'http://foo.bar/{Language}/api',

'server_variables' => ['Language' => ['default' => 'en']],

// ...
]
```

You can also set an oauth client ID and client secret. These values will be automatically prefilled in the authentication view in Swagger UI.

```php
// in config/swagger-ui.php

return [
    // ...

'oauth' => [
        'token_path' => 'oauth/token',
        'refresh_path' => 'oauth/token',
        'authorization_path' => 'oauth/authorize',

'client_id' => env('SWAGGER_UI_OAUTH_CLIENT_ID'),
        'client_secret' => env('SWAGGER_UI_OAUTH_CLIENT_SECRET'),
    ];

// ...
];
```

### Enable and configure MCP Server based on Swagger (OpenAPI v3) files

If you want to use the mcp server that returns info about your swagger files, then you need to install the `laravel/mcp` composer package and enable the swagger server in the config:

```php
// in config/swagger-ui.php

return [
    // ...

'mcp' => [
        'enabled' => true,
    ],

// ...
];
```

By default, the MCP server is protected by the `auth:api` middleware and the `viewSwaggerUI` gate. If you are using Laravel Passport, then you still have to enable the MCP OAuth routes by adding `Mcp::oauthRoutes()` and a Passport authorization view to your codebase.

### Testing

```bash
composer test
```
