🧱 Laravel Brick

Build modular Laravel applications with a solid foundation. Each module is an independent, self-contained unit (a "brick") that can be composed into robust, scalable applications using Domain-Driven Design principles.

"Each module is a brick. Stack them wisely."

✨ Features

📋 Requirements

• PHP 8.1 or higher
• Laravel 9.x, 10.x, or 11.x

📦 Installation

composer require andrebhas/laravel-brick

The package uses Laravel's auto-discovery. The service provider is registered automatically.

Publish Configuration

php artisan vendor:publish --tag=brick-config

Publish Stubs (optional, to customise scaffolding)

php artisan vendor:publish --tag=brick-stubs

🗂 Module Structure

Layer-Driven Architecture (Default)

After running php artisan brick:make, each module follows this structure:

bricks/
└── Hotel/
    ├── module.json                  # Module manifest
    ├── Actions/
    │   └── CreateHotelAction.php
    ├── Models/
    │   └── Hotel.php
    ├── Repositories/
    │   ├── HotelRepositoryInterface.php
    │   └── EloquentHotelRepository.php
    ├── Services/
    │   └── HotelService.php
    ├── Bridge/                      # Optional: inter-module communication
    │   └── HotelBridge.php
    ├── Http/
    │   ├── Controllers/
    │   └── Requests/
    ├── Database/
    │   ├── Migrations/
    │   └── Seeders/
    ├── Routes/
    │   ├── api.php
    │   └── web.php
    ├── Resources/
    │   ├── views/
    │   ├── lang/
    │   └── assets/
    ├── Config/
    │   └── config.php
    ├── Providers/
    │   └── HotelServiceProvider.php
    ├── tests/
    │   ├── Pest.php
    │   ├── Feature/
    │   └── Unit/
    └── README.md

Feature-Driven Architecture

If you prefer to organizer your module by business features rather than technical layers, you can use the --features flag (or answer yes during the interactive prompt). This replaces the Actions directory with a Features directory:

bricks/
└── Hotel/
    ├── Features/
    │   └── CreateHotel/                     # A cohesive, isolated feature
    │       ├── CreateHotelAction.php        # Core logic
    │       ├── CreateHotelRequest.php       # Specific validation
    │       ├── CreateHotelResponse.php      # Formatting Output
    │       └── CreateHotelFeatureTest.php   # Feature tests lives here
    ├── Models/
    ├── Http/
    └── ... (other standard directories)

🚀 Quick Start

1. Create a Module

php artisan brick:make

Interactive flow:

Nama modul:
 > Hotel

Deskripsi modul (opsional):
 > Modul manajemen hotel

Versi modul [1.0.0]:
 >

Buat jembatan (bridge)? (yes/no) [no]:
 > yes

Buat rute API? (yes/no) [no]:
 > yes

Buat rute web? (yes/no) [no]:
 > no

Buat tes (Pest)? (yes/no) [yes]:
 > yes

Gunakan struktur Feature-Driven? (yes/no) [no]:
 > yes

Membuat modul...
✓ Module [Hotel] created successfully

Or non-interactively:

php artisan brick:make Hotel --with-bridge --with-api --with-tests --features

2. Register the Module's Namespace

Add to composer.json:

{
    "autoload": {
        "psr-4": {
            "Bricks\\Hotel\\": "bricks/Hotel/"
        }
    }
}

Then regenerate autoload:

composer dump-autoload

3. Enable the Module

php artisan brick:enable Hotel

4. Run Migrations

php artisan brick:migrate Hotel

📄 Module Manifest (module.json)

{
    "name": "Hotel",
    "description": "Modul manajemen hotel",
    "version": "1.0.0",
    "namespace": "Bricks\\Hotel",
    "active": true,
    "order": 0,
    "dependencies": ["Auth"],
    "bridge": {
        "class": "Bricks\\Hotel\\Bridge\\HotelBridge"
    },
    "author": {
        "name": "Andre Bhaskoro"
    }
}

🌉 Bridge: Cross-Module Communication

1. Implement the Bridge

namespace Bricks\Hotel\Bridge;

use AndreBhas\Brick\Brick\Bridge\Contracts\Bridgeable;

class HotelBridge implements Bridgeable
{
    public static function getBridgeName(): string
    {
        return 'Hotel';
    }

    public static function getExposedMethods(): array
    {
        return ['getById', 'checkAvailability'];
    }

    public function getById(int $id): array
    {
        // Fetch hotel data...
        return ['id' => $id, 'name' => 'Grand Hotel'];
    }

    public function checkAvailability(int $hotelId, string $date): bool
    {
        return true;
    }
}

2. Synchronous Call (from another module)

use AndreBhas\Brick\Brick\Bridge\InternalGateway;

$gateway = app(InternalGateway::class);

// Goes through middleware pipeline (logging, circuit breaker, etc.)
$hotel = $gateway->call('Hotel', 'getById', 42);

3. Asynchronous Call

// Dispatch to queue, get a job ID
$jobId = $gateway->callAsync('Hotel', 'getById', 42);

// Later, poll for the result
$result = $gateway->getAsyncResult($jobId);
// ['status' => 'success', 'result' => [...], 'completed_at' => '...']
// or
// ['status' => 'pending', 'queued_at' => '...']
// or
// ['status' => 'failed', 'error' => '...']

4. Generate Bridge for Existing Module

php artisan brick:make-bridge Hotel

🛡 Circuit Breaker

The circuit breaker prevents cascading failures when a module's bridge is unreliable.

States

• Closed 🟢 — Normal operation; calls pass through
• Open 🔴 — Failures exceeded threshold; calls rejected immediately
• Half-Open 🟡 — Testing recovery with limited trial calls

Configuration (config/brick.php)

'circuit_breaker' => [
    'default' => [
        'threshold'              => 5,  // failures before opening
        'timeout'                => 30, // seconds before half-open
        'half_open_max_attempts' => 3,
    ],
],

Status Command

php artisan brick:bridge:status

+--------+------------+---------------+
| Bridge | State      | Failure Count |
+--------+------------+---------------+
| Hotel  | ● CLOSED   | 0             |
| Auth   | ● OPEN     | 7             |
+--------+------------+---------------+

Manual Reset

php artisan brick:bridge:status --reset=Hotel

🧪 Testing

Package Tests

composer test

Module Tests (Pest)

Each generated module includes its own tests directory with Pest setup:

# Run a specific module's tests
./vendor/bin/pest bricks/Hotel/tests/

Testing Helpers

BridgeFake – Mock bridge calls in tests

use AndreBhas\Brick\Brick\Testing\BridgeFake;
use AndreBhas\Brick\Brick\Bridge\InternalGateway;

$fake = new BridgeFake(
    container: app(),
    cache: app('cache')->store(),
    queue: app('queue'),
);

// Register a fake response
$fake->shouldReceive('Hotel', 'getById', fn ($id) => ['id' => $id, 'name' => 'Test Hotel']);

// Swap in the container
app()->instance(InternalGateway::class, $fake);

// ... run your code ...

// Assert calls
$fake->assertCalled('Hotel', 'getById', 1);
$fake->assertNotCalled('Hotel', 'delete');
$fake->assertNothingCalled(); // if no calls expected

CircuitBreakerFake – Simulate circuit states

use AndreBhas\Brick\Brick\Testing\CircuitBreakerFake;
use AndreBhas\Brick\Brick\Bridge\CircuitBreaker;

$fake = new CircuitBreakerFake();
$fake->forceOpen('Hotel');    // simulate open circuit
$fake->forceHalfOpen('Payment');
$fake->forceClose('Auth');

app()->instance(CircuitBreaker::class, $fake);

Environment Variables

🔧 Adding Custom Middleware

Create a middleware class:

namespace App\Brick\Middleware;

use Closure;

class RateLimitMiddleware
{
    public function handle(Closure $next, string $bridge, string $method, array $args): mixed
    {
        // Rate limiting logic...
        return $next($bridge, $method, $args);
    }
}

Register in config/brick.php:

'middlewares' => [
    \AndreBhas\Brick\Brick\Bridge\Middleware\LoggingMiddleware::class,
    \AndreBhas\Brick\Brick\Bridge\Middleware\CircuitBreakerMiddleware::class,
    \App\Brick\Middleware\RateLimitMiddleware::class, // <-- add here
],

🧩 Module Dependencies

Declare dependencies in module.json:

{
    "name": "Booking",
    "dependencies": ["Hotel", "Auth"]
}

When enabling:

php artisan brick:enable Booking
# Error: Cannot enable [Booking]. Missing dependencies: Hotel (inactive).
# Use --force to override.

php artisan brick:enable Hotel
php artisan brick:enable Booking  # Now works
