Laravel gRPC Validation

A Laravel package for gRPC validation inspired by friendsofhyperf/grpc-validation. This package provides a seamless way to validate gRPC requests in Laravel applications using Attributes.

Features

• Attribute-based Validation: Utilize PHP Attributes to define validation rules directly on your gRPC service methods.
• Flexible Rule Definition: Supports passing validation rules as an array or using a Laravel FormRequest class for more complex validation logic.
• PHP Compatibility: Designed to work with PHP 8.0 and above, ensuring modern PHP features and compatibility.
• Strict Standards: Adheres to PSR standards and passes PHPStan at the strictest level for robust code quality.
• Unit Tested: Comprehensive unit tests are included to ensure reliability and maintainability.
• Final Classes and Strict Types: Uses final classes and strict type declarations for better code integrity and predictability.

Installation

You can install the package via Composer:

composer require hungthai1401/laravel-grpc-validation

Usage

First of all, you need to set up your gRPC server.

use Spiral\RoadRunner\GRPC\InvokerInterface;

$worker = Worker::create();
$invoker = $this->container->make(InvokerInterface::class);
$server = new GrpcServer($invoker);

$server->registerService(..., ...);

// The server will use the configuration from .rr.yaml or environment
$server->serve($worker);

return 0;

Then you need to define your gRPC service methods with validation attributes. Here's an example:

use HT\GrpcValidation\Validation;
use GoodByeFormRequest;

#[Validation(
    rules: [
        'name' => 'required|string|max:10',
        'message' => 'required|string|max:500',
    ],
    messages: [
        'name.required' => 'Name is required',
        'name.string' => 'Name must be a string',
        'name.max' => 'Name must not exceed 10 characters',
        'message.required' => 'Message is required',
        'message.string' => 'Message must be a string',
        'message.max' => 'Message must not exceed 500 characters',
    ],
    attributes: [
        'name' => 'Name',
        'message' => 'Message',
    ],
)]
public function sayHello(HiUser $user) 
{
    $message = new HiReply();
    $message->setMessage("Hello World");
    $message->setUser($user);
    return $message;
}

#[Validation(formRequest: GoodByeFormRequest::class)]
public function sayGoodBye(GoodByeUser $user) 
{
    $message = new GoodByeReply();
    $message->setMessage("Goodbye World");
    $message->setUser($user);
    return $message;
}
