README

A general-purpose modular architecture framework for PHP. Build applications where each module has its own dependency injection container, with carefully controlled sharing through explicit import/export contracts.

💡 Versatile: Works well for CLI tools, data pipelines, background processors, APIs, and complex PHP applications that benefit from clear module boundaries.

✨ Why Modular Framework?

• 🔒 True Encapsulation: Each module has its own isolated DI container
• ⚡ PowerModuleSetup: Extend module functionality without breaking encapsulation
• 🚀 Microservice Ready: Isolated modules can easily become independent services
• 📋 Explicit Dependencies: Import/export contracts make relationships visible
• 🧪 Better Testing: Test modules in isolation with their own containers
• 👥 Team Scalability: Different teams can own different modules
• 🔌 Plugin-Ready: Third-party modules extend functionality safely

🚀 Architectural Vision

This framework is not just another option; it introduces a new architectural paradigm to the PHP ecosystem. It is built on a foundation of runtime-enforced encapsulation and true modularity, inspired by the principles of mature systems like OSGi.

To understand the core innovations and how this framework differs from established solutions like Symfony and Laravel, please read our Architectural Vision Document.

Quick Start

composer require power-modules/framework

use Modular\Framework\App\ModularAppBuilder;

$app = new ModularAppBuilder(__DIR__)
    ->withModules(
        \MyApp\Auth\AuthModule::class,
        \MyApp\Orders\OrdersModule::class,
    )
    ->build();

// Get any exported service
$orderService = $app->get(\MyApp\Orders\OrderService::class);

⚡ PowerModuleSetup Extension System

The framework's most powerful feature - PowerModuleSetup allows extending module functionality without breaking encapsulation:

$app = new ModularAppBuilder(__DIR__)
    ->withModules(UserModule::class, OrderModule::class)
    ->addPowerModuleSetup(new RoutingSetup())    // Adds HTTP routing to modules implementing HasRoutes interface
    ->addPowerModuleSetup(new EventBusSetup())   // Pulls module events and handlers into a central event bus
    ->build();

Available extensions:

• power-modules/router - HTTP routing with PSR-15 middleware
• power-modules/plugin - Plugin architecture for third-party modules
• power-modules/dependency-graph - Visualize module dependencies
• power-modules/dependency-graph-mermaid - Mermaid plugin for dependency graph rendering
• power-modules/console - PowerModuleSetup extension that auto-discovers and registers Symfony Console commands from Power Modules

Coming soon:

• power-modules/events - Event-driven architecture
• Your own! - Create custom PowerModuleSetup implementations for your needs

🚀 Microservice Evolution Path

Start with a modular monolith, evolve to microservices naturally:

Today: Modular monolith

class UserModule implements PowerModule, ExportsComponents {
    public static function exports(): array {
        return [
            UserService::class,
        ];
    }
}

class OrderModule implements PowerModule, ImportsComponents {
    public static function imports(): array {
        return [
            ImportItem::create(UserModule::class, UserService::class),
        ];
    }
}

Later: Independent microservices

class UserModule implements PowerModule, HasRoutes {
    public function getRoutes(): array
    {
        return [
            Route::get('/', UserController::class, 'list'),
        ];
    }

    public function register(ConfigurableContainerInterface $container): void
    {
        $container->set(UserController::class, UserController::class)
            ->addArguments([UserService::class]);
    }
}

class OrderModule implements PowerModule, ImportsComponents {
    // Uses User HTTP API instead of direct service import
}

Your modules are designed with clear boundaries. When you're ready to scale, the module structure supports splitting them into separate services.
