Conclusion

Structuring the application

Avoid complex logic in controllers. Move business logic into dedicated classes to keep the code organized.

Example:

class OrderService {
    public function createOrder(array $data) {
        return Order::create($data);
    }
}

Service classes and the repository pattern

Separating data-access logic helps with testing and maintenance.

class UserRepository {
    public function findByEmail($email) {
        return User::where('email', $email)->first();
    }
}

Form Request Validation

Use Form Requests for validation:

php artisan make:request StorePostRequest

public function rules() {
    return [
        'title' => 'required',
        'content' => 'required'
    ];
}

Eager loading and performance

Avoid multiple queries by using relationships:

Post::with('comments')->get();

Configuration and environment variables

Don't use env() directly in the application — use config files instead.

Logging and debugging

Laravel offers built-in logging:

Log::info('Order created');

For local debugging you can use dd() and dump().

Conclusion

Following Laravel best practices leads to applications that are more scalable, easier to test, and easier to maintain.
