README

A Laravel package that provides a flexible lifecycle management system for your application operations. This package helps you implement consistent patterns for handling events, transactions, logging, authorization, caching, and rate limiting across your Laravel application.

Features

• 🛡️ Authorization Management: Control access with configurable authorization strategies
• 🔄 Transaction Management: Wrap operations in database transactions
• 📊 Logging: Automatically log actions, results, and errors
• 📡 Event Dispatching: Dispatch events before and after operations
• 💾 Caching: Cache operation results for improved performance
• 🚦 Rate Limiting: Protect against abuse with configurable rate limiting
• 🔁 Retry Handling: Automatically retry failed operations with backoff
• 🧩 Strategy Pattern: Choose which features to enable for each operation
• 🔌 Extensible: Create custom strategies for your specific requirements

Installation

You can install the package via composer:

composer require kwidoo/lifecycle

Configuration

Publish the configuration file:

php artisan vendor:publish --provider="Kwidoo\\Lifecycle\\LifecycleServiceProvider"

This will create a config/lifecycle.php file where you can configure default behaviors.

Usage

Basic Usage

use Kwidoo\Lifecycle\Data\LifecycleContextData;
use Kwidoo\Lifecycle\Data\LifecycleOptionsData;
use Kwidoo\Lifecycle\Contracts\Lifecycle;

class YourService
{
    public function __construct(protected Lifecycle $lifecycle) {}

    public function performAction($context)
    {
        $contextData = new LifecycleContextData(
            action: 'create',
            resource: 'users',
            context: $context
        );

        return $this->lifecycle->run($contextData, function ($contextData) {
            // Your business logic here
            $result = $this->createUser($contextData->context);

            return $result;
        }, new LifecycleOptionsData());
    }
}

Customizing Strategy Options

You can use the fluent interface to customize which strategies are enabled:

// Configure strategies with fluent interface
$result = $this->lifecycle->run(
    $contextData,
    function ($contextData) {
        // Business logic
        return $result;
    },
    (new LifecycleOptionsData())
        ->withoutTrx()       // Disable transactions
        ->withEvents()       // Enable events
        ->withoutLogging()   // Disable logging
        ->withCache()        // Enable caching
        ->withRetry()        // Enable retry on failure
);

Lifecycle Data

The package now uses separate data objects for input and output:

// Input context data - immutable
$contextData = new LifecycleContextData(
    action: 'update',      // The action being performed (create, update, delete, etc.)
    resource: 'products',  // The resource being operated on
    context: $product,     // The contextual data for the operation
);

// Execute with lifecycle
$resultData = $this->lifecycle->run($contextData, function($contextData) {
    // Business logic - process the context
    $result = processData($contextData->context);

    // Return the result
    return $result;
});

Events

Events are dispatched with the following naming pattern:

• Before operation: before.{resource}.{action}
• After operation: after.{resource}.{action}
• On error: error.{resource}.{action}

Advanced Usage

Custom Authorizers

You can create custom authorizers for specific resources:

namespace App\Authorizers;

use Kwidoo\Lifecycle\Authorizers\DefaultAuthorizer;

class ProductAuthorizer extends DefaultAuthorizer
{
    public function authorize(string $action, $context): bool
    {
        // Custom authorization logic for products
        if ($action === 'delete' && !$this->userCanDeleteProduct($context)) {
            return false;
        }

        return true;
    }

    protected function userCanDeleteProduct($product): bool
    {
        return auth()->user()->hasPermission('delete-products');
    }
}

Custom Strategy Implementations

You can create custom strategies by implementing the respective interfaces:

namespace App\Strategies\Logging;

use Kwidoo\Lifecycle\Contracts\Strategies\LogStrategy;
use Kwidoo\Lifecycle\Data\LifecycleContextData;

class EnhancedLogStrategy implements LogStrategy
{
    public function execute(LifecycleContextData $data, callable $callback): mixed
    {
        // Custom pre-execution logging
        $this->logWithMetadata($data, 'before');

        // Execute the callback
        $result = $callback();

        // Custom post-execution logging
        $this->logWithMetadata($data, 'after', $result);

        return $result;
    }

    public function logPhase(LifecycleContextData $data, string $phase, string $level = 'info'): void
    {
        // Your custom logging implementation
    }

    protected function logWithMetadata(LifecycleContextData $data, string $phase, $result = null): void
    {
        // Enhanced logging with additional metadata
    }
}

Using Caching

Enable caching for frequently-used operations:

$result = $this->lifecycle->run(
    $contextData,
    function ($contextData) {
        // Expensive operation that will be cached
        return $this->repository->fetchExpensiveData($contextData->context);
    },
    (new LifecycleOptionsData())
        ->withCache()  // Results will be cached
);

Rate Limiting

Protect your application from abuse:

$result = $this->lifecycle->run(
    $contextData,
    function ($contextData) {
        // Operation that needs rate limiting
        return $this->processSensitiveOperation($contextData->context);
    },
    (new LifecycleOptionsData())
        ->withRateLimit()  // Apply rate limiting
);

Testing

composer test

The package includes comprehensive test coverage for all components including:

• Unit tests for all service components
• Strategy implementation tests
• Feature/integration tests demonstrating real-world use cases

Tests are automatically run via GitHub Actions when code is pushed to the repository.
