laravel-validation

Attribute-based validation for Laravel. You declare validation rules directly on a class's properties or on a method's parameters, then validate in one call. The rules live next to the data they describe, so a data object carries its own validation contract.

use Illuminate\Support\Facades\Validator;
use NielsJanssen\Laravel\Validation\Rule\{Email, Max, Min};

final class Registration
{
    #[Min(2), Max(255)]
    public string $name = '';

    #[Email]
    public ?string $email = null;
}

$registration = new Registration();
$registration->name = 'Anouk de Vries';
$registration->email = 'anouk@example.nl';

Validator::validateObject($registration);

Requirements

• PHP 8.5+
• Laravel 13+ (illuminate/validation ^13.15)

Installation

composer require nielsjanssen/laravel-validation

The service provider registers itself through package discovery. It replaces the bound validator factory with a subclass that adds the object and method entry points, keeping the original factory's behaviour intact. There is nothing to publish.

Documentation

• Validation: entry points, type inference, messages, conditional rules, nested objects, iterables, and custom rule attributes.
• Validation rules: every attribute, the generic #[Rule], and ValidationContext.
• GraphQL argument validation: these attributes applied to #[Query] and #[Mutation] parameters.
• Full documentation for the rest of the monorepo.
