Laravel 10 & 11: New Features and Their Impact on PHP Development

Share this post on:

Laravel has always been at the forefront of PHP development, offering elegant syntax and robust functionality. With the release of Laravel 10 and the upcoming Laravel 11, the framework introduces exciting features and improvements that promise to revolutionize the way developers build modern web applications.

In this guide, we’ll explore Laravel 10 and 11 new features, their benefits, and how they impact PHP development. You’ll also find practical coding examples to help you get started.

Laravel 10: Key Features and Enhancements

Released in February 2023, Laravel 10 focuses on developer experience, code quality, and modernization of PHP frameworks.

1. Native Type Declarations in Skeleton Code

Laravel 10 has introduced native type declarations for method arguments and return types in the default skeleton code. This ensures better type safety and improves code readability.

Example: Before and After Type Declarations

Before (Laravel 9):

public function handle($data) {
    return $data;
}

After (Laravel 10):

public function handle(array $data): array {
    return $data;
}

Impact:

  • Reduces bugs caused by type mismatches.
  • Improves IDE auto-completion and static analysis.

2. Process Abstraction Improvements

Laravel 10 introduces a new Process Abstraction layer, making it easier to execute and manage system commands.

Example: Process in Laravel 10

use Illuminate\Support\Facades\Process;

$result = Process::run('ls -la');

if ($result->successful()) {
    echo $result->output();
}

Impact:

  • Simplifies system command execution.
  • Provides a clean and testable API for managing processes.

3. Invokable Validation Rules

Laravel 10 refines validation by introducing Invokable Validation Rules. This approach allows rules to be defined as single-action classes.

Example: Custom Validation Rule

namespace App\Rules;

use Illuminate\Contracts\Validation\InvokableRule;

class Uppercase implements InvokableRule
{
    public function __invoke($attribute, $value, $fail)
    {
        if (strtoupper($value) !== $value) {
            $fail("The $attribute must be uppercase.");
        }
    }
}

Use the rule in a request:

$request->validate([
    'name' => [new Uppercase],
]);

Impact:

  • Encourages reusable and clean validation logic.
  • Simplifies the process of creating custom validation rules.

4. Deprecated Methods Removal

Laravel 10 removes deprecated methods to ensure cleaner code and reduce legacy baggage.

For example, assertDirectoryExists() is now removed in favor of the PHPUnit-native method.

Impact:

  • Encourages developers to adopt modern practices.
  • Reduces maintenance overhead.

Laravel 11: What’s Coming Next?

Laravel 11 is expected to launch in February 2024, building upon the innovations of Laravel 10. Here are the key features expected in Laravel 11.

1. Typed Enum Validation Rules

Laravel 11 introduces native support for typed Enum validation rules, making it easier to work with enums in requests.

Example: Enum Validation Rule

use App\Enums\UserRole;

$request->validate([
    'role' => ['required', new Enum(UserRole::class)],
]);

Impact:

  • Eliminates manual enum validation.
  • Provides stricter type safety for data validation.

2. Enhanced Job Batching

Job batching improvements allow better management of queued tasks. Laravel 11 adds more granular control over batches, making them more robust for large-scale applications.

Example: Enhanced Job Batching

use Illuminate\Bus\Batch;
use Illuminate\Support\Facades\Bus;

Bus::batch([
    new FirstJob(),
    new SecondJob(),
])->then(function (Batch $batch) {
    // All jobs completed successfully
})->catch(function (Batch $batch, Throwable $e) {
    // Handle failed batch
})->dispatch();

Impact:

  • Increases scalability and flexibility for queue management.
  • Simplifies error handling in batch processing.

3. Modern PHP Practices

Laravel 11 is built on PHP 8.2, leveraging features like readonly properties, null safety, and improved performance.

Example: Readonly Properties

class User
{
    public readonly string $email;

    public function __construct(string $email)
    {
        $this->email = $email;
    }
}

Impact:

  • Encourages modern PHP coding standards.
  • Reduces boilerplate code and potential bugs.

4. Built-In Rate Limiting Improvements

Rate limiting gets smarter with Laravel 11, enabling dynamic limits based on user roles or API keys.

Example: Dynamic Rate Limiting

use Illuminate\Support\Facades\RateLimiter;

RateLimiter::for('api', function ($request) {
    return $request->user()->isPremium()
        ? Limit::perMinute(100)
        : Limit::perMinute(20);
});

Impact:

  • Enhances security and performance for APIs.
  • Customizes limits based on user tiers.

Impact on PHP Development

1. Faster Development Cycles

With features like native type declarations and modern validation, Laravel 10 and 11 streamline coding workflows, reducing the time spent on debugging.

2. Higher Code Quality

By enforcing type safety and adopting modern PHP practices, Laravel ensures robust, maintainable codebases that are easier to scale.

3. Improved Developer Experience

Features like Process Abstraction and enhanced job batching reduce complexity, allowing developers to focus on building functionality rather than managing infrastructure.

Practical Coding Examples

Building a Laravel 10 API Endpoint

Here’s an example of a clean and modern API endpoint using Laravel 10.

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\User;

class UserController extends Controller
{
    public function getUser(Request $request, int $id): JsonResponse
    {
        $user = User::findOrFail($id);

        return response()->json($user);
    }
}

Using Laravel 11 Enum Validation

Enums simplify handling predefined values in Laravel 11.

namespace App\Enums;

enum UserRole: string
{
    case Admin = 'admin';
    case User = 'user';
    case Guest = 'guest';
}

Validation Example:

$request->validate([
    'role' => ['required', new Enum(UserRole::class)],
]);
