Laravel Directory Structure Explained: Complete Guide for Beginners and Advanced Developers (2025)

Laravel has established itself as the most popular PHP framework in 2025, powering millions of web applications worldwide. With its elegant syntax, robust features like Eloquent ORM, Blade templating, and Artisan CLI, Laravel simplifies modern web development. However, understanding the Laravel directory structure is fundamental to building scalable, maintainable applications.

Whether you're a complete beginner learning Laravel MVC architecture or an experienced developer looking to master Laravel project structure best practices, this comprehensive guide covers everything you need to know about Laravel's folder organization, including the latest changes in Laravel 11 and Laravel 12.

Why Does Laravel Have a Specific Directory Structure?

Laravel follows the Model-View-Controller (MVC) architectural pattern, a proven design paradigm that separates your application into three interconnected components:

• Model: Handles data logic, database interactions via Eloquent ORM
• View: Manages presentation layer using Blade templates
• Controller: Processes HTTP requests, coordinates between Models and Views

This Laravel MVC architecture provides several critical benefits:

Understanding the Laravel folder structure is essential whether you're building a simple REST API, a complex SaaS application, or learning Laravel for beginners.

Laravel Directory Structure: Complete Breakdown (2025)

When you create a fresh Laravel project using composer create-project laravel/laravel my-app, you'll see a well-organized directory structure. Let's explore each folder in detail:

1Root Directory Files

The root directory contains essential configuration and bootstrapping files:

2app/ Directory - The Heart of Your Application

The app/ directory contains your application's core business logic and is where you'll spend most of your development time. This is the "M" and "C" in the MVC pattern.

3bootstrap/ Directory

The bootstrap/ directory initializes the Laravel framework. It contains:

• app.php - Creates the application instance and binds the Service Container
• cache/ - Framework-generated cache files for performance optimization (routes, config, services)

⚠️ Note: You rarely need to modify files in this directory unless you're customizing framework behavior.

4config/ Directory - Application Configuration

The config/ directory houses all configuration files for your Laravel application. Each file returns an array of configuration options:

// Example: Accessing configuration values
$appName = config('app.name');
$dbConnection = config('database.default');

// Setting configuration at runtime
config(['app.timezone' => 'America/New_York']);

5database/ Directory - Database Management

The database/ directory manages all database-related operations following version-controlled schema management:

# Create a new migration
php artisan make:migration create_posts_table

# Run all pending migrations
php artisan migrate

# Rollback last migration
php artisan migrate:rollback

// database/factories/UserFactory.php
public function definition(): array
{
    return [
        'name' => fake()->name(),
        'email' => fake()->unique()->safeEmail(),
        'password' => Hash::make('password'),
    ];
}

# Create a seeder
php artisan make:seeder ProductSeeder

# Run all seeders
php artisan db:seed

# Run specific seeder
php artisan db:seed --class=ProductSeeder

6public/ Directory - Web Root (Critical for Security)

The public/ directory is the ONLY folder that should be web-accessible. This is Laravel's document root and a critical security feature.

# Create symbolic link for public file storage
php artisan storage:link

# This creates: public/storage -> storage/app/public

7resources/ Directory - Frontend Assets and Views

The resources/ directory contains raw, uncompiled assets and Blade templates (the "V" in MVC):

php artisan make:view posts.index

{{ __('messages.welcome') }}

npm run dev
npm run build

8routes/ Directory - Application Endpoints

The routes/ directory defines all HTTP endpoints for your application. Understanding routing is crucial for Laravel MVC architecture:

// routes/web.php - Example web routes
Route::get('/', function () {
    return view('welcome');
});

Route::get('/posts', [PostController::class, 'index'])->name('posts.index');
Route::resource('products', ProductController::class);

// routes/api.php - Example API routes (prefixed with /api)
Route::get('/users', [UserController::class, 'index']);
Route::post('/posts', [PostController::class, 'store'])->middleware('auth:sanctum');

9storage/ Directory - Generated Files and Logs

The storage/ directory stores application-generated files, caches, and logs. This directory must have write permissions.

# View latest logs
tail -f storage/logs/laravel.log

# Clear old logs
php artisan log:clear

10tests/ Directory - Automated Testing

Laravel encourages Test-Driven Development (TDD) with built-in PHPUnit support. The tests/ directory contains your test suite:

php artisan make:test PostControllerTest

php artisan make:test UserTest --unit

# Run all tests
php artisan test

# Run specific test file
php artisan test --filter=PostControllerTest

# Run tests with coverage
php artisan test --coverage

11vendor/ Directory - Third-Party Dependencies

The vendor/ directory is managed by Composer and contains all third-party PHP packages including the Laravel framework itself.

Laravel 11 vs Laravel 12: Directory Structure Changes

Laravel 11 introduced significant structural improvements focused on minimalism and developer experience. Laravel 12 continues this philosophy while adding new features.

// bootstrap/app.php (Laravel 11+)
return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        commands: __DIR__.'/../routes/console.php',
    )
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->web(append: [
            HandleInertiaRequests::class,
        ]);
    })->create();

php artisan config:publish database

Understanding Service Container and Service Providers

The Service Container (also called IoC Container) and Service Providers are fundamental concepts in Laravel architecture that power dependency injection and application bootstrapping.

What is the Laravel Service Container?

The Service Container is Laravel's dependency injection container that manages class dependencies and performs automatic resolution. Think of it as a powerful factory that knows how to build objects.

// Automatic dependency injection in controller
class PostController extends Controller
{
    // Laravel automatically resolves and injects PostRepository
    public function __construct(
        protected PostRepository $repository
    ) {}
    
    public function index()
    {
        return $this->repository->all();
    }
}

// Manual container binding in AppServiceProvider
public function register(): void
{
    $this->app->bind(PostRepositoryInterface::class, EloquentPostRepository::class);
    
    // Singleton binding (single instance)
    $this->app->singleton(CacheManager::class, function ($app) {
        return new CacheManager($app['config']['cache']);
    });
}

What are Service Providers?

Service Providers are the central place for configuring your application. They register bindings in the Service Container and bootstrap services. Located in app/Providers/.

// app/Providers/AppServiceProvider.php
class AppServiceProvider extends ServiceProvider
{
    // Register bindings into the Service Container
    public function register(): void
    {
        $this->app->bind(PaymentGateway::class, StripeGateway::class);
    }
    
    // Bootstrap any application services
    public function boot(): void
    {
        // Configure View composers
        View::composer('profile', ProfileComposer::class);
        
        // Extend validators
        Validator::extend('strong_password', function($attribute, $value) {
            return preg_match('/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).+$/', $value);
        });
    }
}

Laravel Project Structure Best Practices (2025)

// Controller with too much logic
public function store(Request $request)
{
    $user = User::create($request->all());
    Mail::to($user)->send(new Welcome());
    event(new UserRegistered($user));
    Cache::forget('users_count');
    Log::info('User registered: '.$user->email);
    return redirect('/dashboard');
}

// Thin controller using service
public function store(
    StoreUserRequest $request,
    UserService $service
) {
    $user = $service->register($request->validated());
    return redirect('/dashboard');
}
