Install Laravel Auth (if not installed)

 Good question 👍

I’ll show you step by step logout system in Laravel 10 using 4-Layer Architecture with proper structure.

We will follow this structure:

Controller → Service → Repository → Model

---

✅ Step 1: Install Laravel Auth (if not installed)

If you don’t have authentication installed:

composer require laravel/breeze --dev
php artisan breeze:install
npm install
npm run build
php artisan migrate

Now login/register system is ready.

---

✅ Step 2: Create 4-Layer Structure

If you don’t already have layers, create them.

Create folders:

app/
 ├── Http/Controllers
 ├── Services
 ├── Repositories
 │     ├── Contracts
 │     └── Eloquent

---

✅ Step 3: Create Repository Interface

📁 app/Repositories/Contracts/AuthRepositoryInterface.php

<?php

namespace App\Repositories\Contracts;

interface AuthRepositoryInterface
{
    public function logout();
}

---

✅ Step 4: Create Repository Implementation

📁 app/Repositories/Eloquent/AuthRepository.php

<?php

namespace App\Repositories\Eloquent;

use App\Repositories\Contracts\AuthRepositoryInterface;
use Illuminate\Support\Facades\Auth;

class AuthRepository implements AuthRepositoryInterface
{
    public function logout()
    {
        Auth::logout();
    }
}

---

✅ Step 5: Bind Repository in AppServiceProvider

Open:

📁 app/Providers/AppServiceProvider.php

Add inside register():

use App\Repositories\Contracts\AuthRepositoryInterface;
use App\Repositories\Eloquent\AuthRepository;

public function register(): void
{
    $this->app->bind(AuthRepositoryInterface::class, AuthRepository::class);
}

---

✅ Step 6: Create Auth Service

📁 app/Services/AuthService.php

<?php

namespace App\Services;

use App\Repositories\Contracts\AuthRepositoryInterface;

class AuthService
{
    protected $authRepository;

    public function __construct(AuthRepositoryInterface $authRepository)
    {
        $this->authRepository = $authRepository;
    }

    public function logout()
    {
        return $this->authRepository->logout();
    }
}

---

✅ Step 7: Create Controller

php artisan make:controller AuthController

📁 app/Http/Controllers/AuthController.php

<?php

namespace App\Http\Controllers;

use App\Services\AuthService;
use Illuminate\Http\Request;

class AuthController extends Controller
{
    protected $authService;

    public function __construct(AuthService $authService)
    {
        $this->authService = $authService;
    }

    public function logout(Request $request)
    {
        $this->authService->logout();

        $request->session()->invalidate();
        $request->session()->regenerateToken();

        return redirect('/login');
    }
}

---

✅ Step 8: Add Route

📁 routes/web.php

use App\Http\Controllers\AuthController;

Route::post('/logout', [AuthController::class, 'logout'])->name('logout');

---

✅ Step 9: Add Logout Button in Blade

<form method="POST" action="{{ route('logout') }}">
    @csrf
    <button type="submit">Logout</button>
</form>

⚠️ Logout must be POST request (not GET).

---

🔥 Flow Explanation

When user clicks logout:

Blade Form
   ↓
Route
   ↓
AuthController
   ↓
AuthService
   ↓
AuthRepository
   ↓
Auth::logout()

Then session invalidated → user redirected to login.

---

🎯 Important (Security)

This is important:

$request->session()->invalidate();
$request->session()->regenerateToken();

It protects from session fixation attack.

---

🎉 All Commands Used

composer require laravel/breeze --dev
php artisan breeze:install
npm install
npm run build
php artisan migrate
php artisan make:controller AuthController

If you want, I can also show:

• ✅ Login in 4-layer architecture

• ✅ Register in 4-layer

• ✅ API logout (Sanctum)

• ✅ Livewire logout

• ✅ Complete Auth 4-layer project structure

Just tell me 👍
