What is Laravel 12

Laravel 12 is the latest major release of the Laravel PHP framework, built for modern, high-performance web applications. It introduces a restructured project layout, enhanced query and ORM features, asynchronous caching, AI-assisted debugging, and improved developer tools for faster and more secure development.

Laravel Versions and Support Timeline

Each Laravel release receives bug fixes for 18 months and security fixes for 2 years. This predictable cycle ensures applications remain stable and secure:

1. New Application Structure: Cleaner and Organized

Laravel 12 simplifies the project structure for faster navigation:

• app/Models is optional: Models can live directly in app/.
• Config files centralized: All configuration now in config/*.
• Routes grouped by type: Separate folders for API, web, and console routes.

  Before (Laravel 11):
  app/
  ├── Console/
  ├── Exceptions/
  ├── Http/
  │   ├── Controllers/
  │   └── Kernel.php
  routes/
  ├── web.php
  ├── api.php

  After (Laravel 12):
  app/
  ├── Http/
  │   └── Controllers/
  ├── Models/          # Optional
  └── Kernel.php
  routes/
  ├── web/
  │   └── web.php
  ├── api/
  │   └── v1.php       # Built-in API versioning
  

2. Advanced Query Builder: nestedWhere()

Nested conditions are simpler with nestedWhere():

  // Before Laravel 12
  Order::where(function ($q) {
      $q->where('status', 'pending')
        ->orWhere(function ($q) {
            $q->where('amount', '>', 100)
              ->where('priority', 'high');
        });
  })->get();

  // After Laravel 12
  Order::nestedWhere(function ($q) {
      $q->where('status', 'pending')
        ->orWhere('amount', '>', 100)
        ->where('priority', 'high');
  })->get();
  

3. Stronger Security: secureValidate()

Secure password policies are enforced automatically:

  // Before
  $request->validate([
      'password' => ['required', 'min:12', 'regex:/[A-Z]/', 'regex:/[0-9]/']
  ]);

  // After
  $request->secureValidate(['password' => 'required|secureValidate']);
  

4. Native GraphQL Support for APIs

Laravel 12 supports first-party GraphQL integration, making API development faster and cleaner. You can define schemas and query endpoints without third-party packages.

5. AI-Powered Debugging: debug()

Debugging is now smarter with real-time AI suggestions, including contextual fixes for common errors.

  debug($product->load('reviews'));
  // Outputs the product with reviews + SQL query log
  

6. Asynchronous Caching

Cache heavy operations without blocking user requests:

  // Before
  $topProducts = Cache::remember('top-products', 3600, function () {
      return Product::popular()->get();
  });

  // After
  $topProducts = Cache::async()->remember('top-products', 3600, function () {
      return Product::popular()->get(); // Runs in background
  });
  

7. Real-Time Features: WebSocket Support

Build live features like chat or dashboards without external services:

  php artisan websocket:serve

  class ChatMessage implements ShouldBroadcast {
      public function broadcastOn() {
          return new Channel('room');
      }
  }
  

8. Smarter Artisan CLI

Interactive commands reduce boilerplate and speed up development:

  php artisan make:controller
  ❓ Controller type? > API
  ❓ Generate CRUD? > Yes
  ✅ Controller created at app/Http/Controllers/Api/UserController.php
  

9. Enhanced Eloquent ORM

Conditional eager loading, filtered relationships, and constraints simplify database interactions:

  User::withFiltered('orders', ['status' => 'completed'])->get();
  

10. Job & Queue Management

Dynamic prioritization and delayed retries improve background task orchestration:

  dispatch(new SendInvoice($invoice))->prioritize('high');
  

11. Modern DevOps Integration

Automated deployment commands like deploy:prepare streamline cache clearing, migrations, and asset compilation.

Deprecated Functions in Laravel 12

• Removal of restore() in global scopes.
• Route helper supports only string-based routes.
• Array-based relationship definitions in models are deprecated.
• Validation rule same replaced with compare.
• Old helper functions like parse_url() replaced with Url facade.

Conclusion:

Laravel 12 delivers a faster, more secure, and developer-friendly framework. From improved performance and asynchronous caching to AI-assisted debugging and WebSocket support, it equips developers to build scalable modern applications efficiently.
