Simple to use OpenAPI 3 compatible documentation generator.
Also includes OpenAPI UI.

About

1. OAS3 support
2. Automatic generation (assuming relevant configuration option is turned on)
3. Includes of OpenAPI UI
4. Uses PHP 8 Attributes

Requirements

This package developed on Laravel 8.19.0, but it might work on the previous releases.
All other requirements are inherited from the Laravel 8.
###PHP 8 is required for this package to work

Installation

Install package through composer

composer require freedomcore/laravel-openapi

Publish configuration files and views

php artisan vendor:publish --provider "FreedomCore\OpenAPI\OpenAPIServiceProvider"

Edit the openapi.php configuration file for your liking

What is included

Out of the box this package can work with FormRequest, it is also able to generate valid code for the method parameters when they are included in query | path, so there will be no duplicates and in: **** will also be assigned correctly.

Usage

FreedomCore\OpenAPI\Attributes\Controller

Controller attribute allows you to mark class as a Controller.
This will help generator to recognize classes and create appropriate tags for routes.

/**
 * Class User
 * @package App\Http\Controllers\User
 */
#[FreedomCore\OpenAPI\Attributes\Controller(
    name: 'User',
    description: 'User related endpoints'
)]
class User extends Controller {

}

FreedomCore\OpenAPI\Attributes\Request\*

There are total of 5 types of requests currently supported by this package.

• FreedomCore\OpenAPI\Attributes\Request\Delete

/**
 * Delete constructor.
 * @param string $description
 * @param bool $deprecated
 */
public function __construct(string $description = '', bool $deprecated = false) {
    parent::__construct('DELETE', $description, $deprecated);
}

• FreedomCore\OpenAPI\Attributes\Request\Get

/**
 * Get constructor.
 * @param string $description
 * @param bool $deprecated
 */
public function __construct(string $description = '', bool $deprecated = false) {
    parent::__construct('GET', $description, $deprecated);
}

• FreedomCore\OpenAPI\Attributes\Request\Patch

/**
 * Patch constructor.
 * @param string $description
 * @param bool $deprecated
 */
public function __construct(string $description = '', bool $deprecated = false) {
    parent::__construct('PATCH', $description, $deprecated);
}

• FreedomCore\OpenAPI\Attributes\Request\Post

/**
 * Post constructor.
 * @param string $description
 * @param bool $deprecated
 */
public function __construct(string $description = '', bool $deprecated = false) {
    parent::__construct('POST', $description, $deprecated);
}

• FreedomCore\OpenAPI\Attributes\Request\Put

/**
 * Put constructor.
 * @param string $description
 * @param bool $deprecated
 */
public function __construct(string $description = '', bool $deprecated = false) {
    parent::__construct('PUT', $description, $deprecated);
}

You dont have to use these Attributes unless you want to add description to the resource, possible request types will be inferred from Laravel routing system.

FreedomCore\OpenAPI\Attributes\Response\*

There are total of 18 types of responses currently supported by this package.
They do come with the correct response codes attached to them, so the only thing you have to do (or not) is add description.

This is the base class:

<?php namespace FreedomCore\OpenAPI\Attributes\Response;

use Attribute;

/**
 * Class Response
 * @package FreedomCore\OpenAPI\Attributes\Response
 */
#[Attribute(Attribute::TARGET_METHOD)]
class Response {

    /**
     * Response code
     * @var int
     */
    public int $code;

    /**
     * Response description
     * @var string
     */
    public string $description;

    /**
     * Response constructor.
     * @param int $code
     * @param string $description
     */
    public function __construct(int $code, string $description) {
        $this->code = $code;
        $this->description = $description;
    }

}

And this is the example of FreedomCore\OpenAPI\Attributes\Response\Ok response:

<?php namespace FreedomCore\OpenAPI\Attributes\Response;

use Attribute;

/**
 * Class Ok
 * @package FreedomCore\OpenAPI\Attributes\Response
 */
#[Attribute(Attribute::TARGET_METHOD)]
class Ok extends Response {

    /**
     * Ok constructor.
     * @param string $description
     */
    public function __construct(string $description = '') {
        parent::__construct(200, $description);
    }

}
