OpenAPI Laravel

About

Validate HTTP Requests and Responses with OpenAPI Specs.

Install

Require the package with composer.

composer require rogervila/openapi-laravel

Laravel will autodiscover the service provider located in \LaravelOpenAPI\ServiceProvider.

Setup

The package handles HTTP requests via Specification and Request classes.

OpenAPI Specifications

First, create a Specification class.

# The namespace is optional, you can place specification classes anywhere.
php artisan openapi:make-specification Specifications/PetsSpecification

<?php

namespace App\Specifications;

use LaravelOpenAPI\Specification\YamlSpecification;
use LaravelOpenAPI\Specification\JsonSpecification;

// The Specification class must implement YamlSpecification or JsonSpecification interface.
class PetsSpecification implements YamlSpecification
{
    public function __invoke(): string
    {
        // As long as it returns a yaml or json string, you can resolve it as needed.
        return file_get_contents(storage_path('openapi/pets.yml'));
        
        // Another example (JSON in this case)
        // return \Cache::rememberForever(self::class, fn () => \Http::get('https://petstore3.swagger.io/api/v3/openapi.json')->body());
    }
}

OpenAPI Requests

Once a Specification is set, You can create OpenAPI Request and define which specification it should use.

The package will handle the request validation based on the specification.

• If it does not match, it will return a "422 validation error".
• If the specification is missing, it will return a "501 not implemented" error.

# Requests are placed on \App\Http\Requests\OpenAPI namespace
php artisan openapi:make-request PetRequest

OpenAPI Requests extend from \Illuminate\Foundation\Http\FormRequest, so you might implement additional rules and authorization as defined on laravel docs

<?php

namespace App\Http\Requests\OpenAPI;

use LaravelOpenAPI\Request;

class PetRequest extends Request
{
    /** {@inheritDoc} */
    public function getSpecification(): string
    {
        return \App\Specifications\PetsSpecification::class;
    }
}

Usage

The package includes the \LaravelOpenAPI\OpenAPI class as an accessor for all the package features.

Check this repository's laravel folder to see the package usage on a real laravel project.

Example

This example defines a FindPetByIdController controller which uses the package to handle the request and the response.

<?php

namespace App\Http\Controllers\Pet;

use App\Http\Controllers\Controller;
use App\Http\Requests\OpenAPI\PetRequest;
use App\Http\Resources\PetResource;
use App\Models\Pet;
use Illuminate\Http\JsonResponse;
use LaravelOpenAPI\OpenAPI;

// GET /api/pet/{petId}
class FindPetByIdController extends Controller
{
    public function __invoke(PetRequest $request, int $petId): JsonResponse
    {
        if (is_null($pet = Pet::find($petId))) {
            OpenAPI::abort(JsonResponse::HTTP_NOT_FOUND)->forRequest($request);
        }

        return OpenAPI::response(new PetResource($pet))->forRequest($request);
    }
}
