bchalier/laravel-openapi-autodoc

Laravel OpenAPI Autodoc

Generates OpenAPI v3 documentation from your Laravel routes, FormRequests and API Resources.

Compatible with Laravel 10–12 and PHP 8.1–8.4.

Install

1. Require the package in your app (Composer path repo supported):

2. Publish the config if you need to customize:

php artisan vendor:publish --tag=config --provider="Bchalier\LaravelOpenapiDoc\App\Providers\LoadingServiceProvider"

Usage

• Generate the JSON file:
  • php artisan documentation:generate
• Output file:
  • Stored on the public disk at storage/app/public/documentation/openapi.json.
  • If you’ve run php artisan storage:link, it’s available at /storage/documentation/openapi.json.

How it works

• Parses route list and filters via config/documentation.php.
• Infers request schemas from FormRequest validation rules.
• Infers response schemas from return types: JsonResource, ResourceCollection, JsonResponse.
• Uses docblocks for operation summary/description and @throws to add error responses.

Notes

• Models instantiated for resources must use Illuminate\Database\Eloquent\Factories\HasFactory.
• When route names are missing, operationId falls back to <method>_<uri>.
