🎯 Generated Code Examples

Role-Based Middleware

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class AdminMiddleware
{
    /**
     * Handle an incoming request.
     * 
     * @param  string  $role  Required role
     */
    public function handle(Request $request, Closure $next, string $role = 'admin'): Response
    {
        // Check if user has role = $role
        if ($request->user() && $request->user()->role === $role) {
            return $next($request);
        }

        return response()->json([
            'message' => 'Administrator access required',
            'code' => 403
        ], 403);
    }
}

Permission-Based Middleware

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class CanEditMiddleware
{
    /**
     * Handle an incoming request.
     * 
     * @param  string  $permission  Required permission
     */
    public function handle(Request $request, Closure $next, string $permission = 'edit-posts'): Response
    {
        // Check if user has permission: $permission
        if ($request->user() && $request->user()->can($permission)) {
            return $next($request);
        }

        return response()->json([
            'message' => 'Insufficient permissions',
            'code' => 403
        ], 403);
    }

class InternalMiddleware
{
    /**
     * Handle an incoming request.
     */
    public function handle(Request $request, Closure $next): Response
    {
        // Check if request IP is in allowed list: 192.168.1.1,127.0.0.1
        if (in_array($request->ip(), ['192.168.1.1', '127.0.0.1'])) {
            return $next($request);
        }

        return response()->json([
            'message' => 'IP address not allowed',
            'code' => 403
        ], 403);
    }

    /**
     * Get allowed IP addresses
     */
    protected function getAllowedIps(): array
    {
        return ['192.168.1.1', '127.0.0.1'];
    }
}

🧪 Generated Test Example

<?php

namespace Tests\Unit\Middleware;

use Tests\TestCase;
use Illuminate\Http\Request;
use App\Http\Middleware\AdminMiddleware;
use Illuminate\Foundation\Testing\RefreshDatabase;

class AdminMiddlewareTest extends TestCase

    /** @test */
    public function it_allows_access_when_condition_met()
    {
        // TODO: Implement test based on your middleware logic
        $request = new Request();
        $middleware = new AdminMiddleware();
        
        $response = $middleware->handle($request, function ($req) {

3. Auth Configuration - Updated config/auth.php for roles
4. Route Examples - Added to routes/api.php or routes/web.php
5. Test Files - Generated in tests/Unit/Middleware/

💡 Best Practices

Use Boolean Fields for Single Roles

php artisan middleware:generate SuperAdmin --boolean --field=is_super_admin

Custom HTTP Status Codes

php artisan middleware:generate Auth --code=401 --message="Authentication required"

API-Focused Middleware

php artisan middleware:generate ApiAuth --guard=api --test

Internal API Protection

php artisan middleware:generate InternalApi --type=ip --ip="10.0.0.0/8" --log

🐛 Troubleshooting

Middleware not found in routes?

• Run php artisan route:list to see registered middleware
• Check Kernel.php for proper registration

Authentication not working?

• Verify guard configuration in config/auth.php
• Check user model field names match middleware configuration

Tests failing?

• Implement actual test logic in generated test files
• Mock user authentication in tests
