The Laravel Modular Architecture Implementation in Brief

Laravel, by default, follows the Monolithic Architecture where all application logic (controllers, models, services, etc.) resides in the app/ directory. However, as projects grow, maintaining a large codebase within a monolithic structure becomes challenging.

To solve this, Laravel supports Modular Architecture, where your application is split into multiple independent modules. Each module contains its own controllers, models, views, routes, and configurations, thus making it more scalable, maintainable, and reusable.

This approach is ideal for complex applications, such as an Office Furniture Online System, where we can separate functionalities like Inventory Management, Orders, Payments, and User Accounts into different modules.

What is Modular Architecture?

Modular architecture is a software design approach where an application is divided into self-contained modules, each handling a specific feature. Each module operates independently while interacting with others when needed.

For instance, in an online office furniture system, we can have separate modules for:

• Product Management (Handling office furniture products)
• Order Management (Processing orders and tracking deliveries)
• User Management (Customer accounts or admins, and vendors)
• Payment Gateway (Managing transactions securely)
• Warehouse Management (Tracking inventory across locations)

Each module will have its own controllers, models, views, and routes, ensuring better separation of concerns.

Why Use Modular Architecture in Laravel?

Traditional monolithic applications store everything inside Laravel’s default MVC (Model-View-Controller) structure, making it hard to scale as the codebase grows. Modular architecture solves this by grouping related features into separate modules.

Modular Architecture Key Benefits:

✔ Scalability: Adding new features doesn’t affect the entire system, you only need to concentrate on one module at a time.
✔ Code Reusability: Modules can be reused across multiple projects. For instance; the payments or authentication modules can be reused in other projects.
✔ Team Collaboration: Different teams can work on separate modules without conflicts.
✔ Easy Maintenance: Bugs or updates in one module don’t impact others, they’re accommodated and solved in isolation. Each module is self-contained with reduced dependencies.
✔ Better Organization: The project remains structured and easy to navigate.
✔ Easy Testing — Modules can be tested independently.

Implementing Modular Architecture in Laravel (Step-by-Step Guide)

Laravel doesn’t provide built-in modular support, but we can implement it using custom modules or packages like nwidart/laravel-modules. Below is a step-by-step guide using nwidart/laravel-modules.

Step 1: Install Laravel & Nwidart Package

Ensure you have a Laravel project ready. If not, install Laravel:

composer create-project laravel/laravel office-furniture-system
cd office-furniture-system

Now install the nwidart/laravel-modules package:

composer require nwidart/laravel-modules

Step 2: Generate a Module

Let’s create a Product module for managing office furniture products:

php artisan module:make Product

This creates a new module inside Modules/Product, which contains:

Modules/
  ├── Product/
  │   ├── Config/          # Configuration files  
  │   ├── Database/        # Migrations, factories, seeders  
  │   ├── Http/            # Controllers, middleware  
  │   ├── Models/          # Eloquent models  
  │   ├── Routes/          # Module-specific routes  
  │   ├── Resources/       # Views, translations  
  │   ├── Services/        # Business logic (optional)

Step 3: Define Routes for the Product Module

In Modules/Product/Routes/web.php:

use Modules\Product\Http\Controllers\ProductController;
Route::prefix('product')->group(function () {
    Route::get('/', [ProductController::class, 'index']);
    Route::get('/{id}', [ProductController::class, 'show']);
});

Step 4: Create a Product Controller

Generate a controller inside the Product module:

php artisan module:make-controller ProductController Product

Modify Modules/Product/Http/Controllers/ProductController.php:

namespace Modules\Product\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Routing\Controller;
use Modules\Product\Models\Product;

class ProductController extends Controller
{
    public function index()
    {
        return response()->json(Product::all());
    }

    public function show($id)
    {
        return response()->json(Product::findOrFail($id));
    }
}

Step 5: Define the Product Model

In Modules/Product/Models/Product.php:

namespace Modules\Product\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = ['name', 'description', 'price', 'stock'];
}

Step 6: Create Migrations for Products

Generate a migration:

php artisan module:make-migration create_products_table Product

Modify Modules/Product/Database/Migrations/xxxx_xx_xx_xxxxxx_create_products_table.php: — replace the “xxxx_xx_xx_xxxxxx" with your directory file path details.

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->text('description')->nullable();
        $table->decimal('price', 10, 2);
        $table->integer('stock');
        $table->timestamps();
    });
}

Run the migration:

php artisan module:migrate Product

Step 7: Load Module Automatically

To ensure Laravel loads modules dynamically, add this to config/app.php:

'providers' => [    
    Nwidart\Modules\LaravelModulesServiceProvider::class,
],

And in composer.json, add:

"autoload": {
    "psr-4": {
        "App\\": "app/",
        "Modules\\": "Modules/"
    }
}
}

Run:

composer dump-autoload

Now, visiting /product returns all products, and /product/{id} fetches a specific product using the id.

Modularizing an Online Office Furniture System in Laravel

For our online office furniture system, we can create multiple modules:

1. Product Module

• Manages office furniture items (desks, chairs, cabinets)
• Routes: /product, /product/{id}

2. Order Module

• Handles customer orders and status tracking
• Routes: /order, /order/{id}

3. User Module

• Manages customers, admins, and vendors
• Routes: /user/profile, /user/orders

4. Payment Module

• Integrates payment gateways (PayPal, Stripe)
• Routes: /payment/process, /payment/status

Each module is independently developed and deployed.

Challenges of Laravel Modular Architecture

❌ Initial Setup Complexity — Requires extra configuration compared to the usual monolithic approach.
❌ Inter-Module Communication — Sharing data between modules needs APIs or event-based communication.
❌ Code Duplication Risk — If not managed properly, common logic might be duplicated across modules.

Best Way to Use

Use Laravel’s modular architecture for large-scale applications as its a powerful approach to splitting features into independent modules. With this strategic system design, the system becomes scalable, maintainable, and team-friendly.

With tools like nwidart/laravel-modules, implementing modularity is seamless, making Laravel an ideal framework for structured, efficient application development.
