20 Laravel Features You Should Know in 2023

Laravel is a popular PHP framework that continuously evolves, adding new features and improvements to simplify and accelerate web development. This article explores twenty Laravel features you should be aware of in 2023.

1. Blade Components

Blade components allow you to encapsulate UI logic and reuse it throughout your application, providing a clean, modular way to organize views and make your code easier to maintain.

<code>&lt;x-alert type="success"&gt;
    Welcome to my website!
&lt;/x-alert&gt;</code>

2. Livewire Integration

Livewire is a full‑stack framework for Laravel that lets you build interactive UI components without writing JavaScript, enabling real‑time, responsive user interfaces.

<code>class Counter extends Component
{
    public $count = 0;

    public function increment()
    {
        $this->count++;
    }

    public function render()
    {
        return view('livewire.counter');
    }
}
</code>

3. Laravel Sanctum

Sanctum provides a lightweight authentication system for SPAs, mobile apps, and simple token‑based APIs, making it easy to protect your API and authenticate users.

<code>use Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;
}
</code>

4. Laravel Airlock

Airlock (now part of Sanctum) offers another token‑based authentication system designed for SPAs and mobile apps, allowing simple API token issuance without session overhead.

<code>use Laravel\Airlock\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;
}
</code>

5. Job Batching

Job batching lets you group multiple jobs into a single batch and execute them together, improving performance when handling large numbers of jobs.

<code>Batch::dispatch([
    new ProcessPodcast($podcast1),
    new ProcessPodcast($podcast2),
    new ProcessPodcast($podcast3),
])->then(function (Batch $batch) {
    // All jobs completed successfully...
})->catch(function (Batch $batch, Throwable $e) {
    // An error occurred while processing the batch...
});
</code>

6. Model Factories

Model factories let you define blueprints for generating fake data, useful for testing or seeding large amounts of realistic data during development.

<code>use Illuminate\Database\Eloquent\Factories\Factory;

class UserFactory extends Factory
{
    protected $model = User::class;

    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'email' => $this->faker->unique()->safeEmail,
            'password' => bcrypt('password'),
            'remember_token' => Str::random(10),
        ];
    }
}
</code>

7. Laravel Telescope

Telescope is a powerful debugging assistant that lets you inspect requests, view database queries, monitor jobs, and more, providing valuable insight for debugging and optimizing Laravel applications.

8. Laravel Echo

Echo is a JavaScript library that simplifies using WebSockets in Laravel applications, offering an elegant API for sending and receiving real‑time events such as chat messages and notifications.

<code>Echo.channel('chat-room')
    .listen('MessagePosted', (e) => {
        console.log(e.message);
    });
</code>

9. Queued Event Listeners

Event listeners can now be queued, allowing them to run asynchronously in the background, which improves response times and makes applications more responsive.

<code>class SendWelcomeEmail implements ShouldQueue
{
    use Queueable;

    public function handle(UserRegistered $event)
    {
        // Send welcome email to the user...
    }
}
</code>

10. Laravel Mix

Mix is an asset compilation tool that provides a clean API for defining Webpack builds, simplifying the compilation, optimization, and inclusion of CSS and JavaScript assets.

<code>mix.js('resources/js/app.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css')
    .sourceMaps();
</code>

11. Laravel Dusk

Dusk is Laravel's first browser automation testing tool, enabling expressive, easy‑to‑read tests that simulate user interactions and verify application behavior.

<code>public function testLogin()
{
    $this->browse(function ($browser) {
        $browser->visit('/login')
                ->type('email', '[email protected]')
                ->type('password', 'secret')
                ->press('Login')
                ->assertPathIs('/dashboard');
    });
}
</code>

12. Route Model Binding Improvements

Laravel 8 enhances route model binding with custom resolvers, giving you finer control over how models are retrieved and bound to route parameters.

<code>public function boot()
{
    Route::bind('user', function ($value) {
        return User::findBySlug($value) ?? abort(404);
    });
}
</code>

13. Laravel Horizon

Horizon provides a beautiful dashboard and code‑based configuration for monitoring and managing Laravel queues, offering real‑time insight into queue workers and performance.

14. Route Caching

Route caching compiles your route definitions into a single file, dramatically speeding up route registration and improving application performance, especially for large route sets.

<code>php artisan route:cache</code>

15. Laravel Scout

Scout is a full‑text search package that integrates seamlessly with Laravel, offering a simple, elegant way to search Eloquent models using drivers such as Algolia or Elasticsearch.

<code>use Laravel\Scout\Searchable;

class Product extends Model
{
    use Searchable;
    // ...
}
</code>

16. Laravel Cashier

Cashier provides a smooth interface for handling subscription billing, invoices, and other payment‑related tasks, simplifying the integration of subscription services into Laravel apps.

<code>use Laravel\Cashier\Billable;

class User extends Authenticatable
{
    use Billable;
    // ...
}
</code>

17. Eloquent Subquery Enhancements

Laravel 8 adds subquery capabilities to Eloquent, allowing you to define and reuse subqueries directly within the query builder for more complex data retrieval.

<code>latestPosts = DB::table('posts')
    ->select('title')
    ->where('created_at', '>', function ($query) {
        $query->select('created_at')
              ->from('posts')
              ->orderByDesc('created_at')
              ->limit(1);
    })
    ->get();
</code>

18. Eloquent Dynamic Relationships

Dynamic relationships let you define relationships at runtime without declaring them in the model class, offering greater flexibility for handling dynamic data structures.

<code>public function products()
{
    return $this->hasManyThrough(
        $this->category->productModel,
        $this->category,
        'shop_id',
        'category_id',
        'id',
        'id'
    );
}
</code>

19. Eloquent Automatic Date Casting

Automatic date casting converts date columns to Carbon instances automatically, simplifying date manipulation within Eloquent models.

<code>protected $casts = [
    'created_at' => 'datetime',
    'updated_at' => 'datetime',
];
</code>

20. Laravel API Resources

API resources provide a convenient way to transform Eloquent models into JSON responses, allowing you to customize the output and include additional data.

<code>class UserResource extends JsonResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
        ];
    }
}
</code>

Conclusion

Laravel continues to evolve, delivering new features and improvements that help developers build higher‑quality applications more efficiently.
