Core Concepts

Understanding the Basics

The foundation of Laravel 13 rests on several key principles:

• Simplicity: Start small and iterate
• Composability: Build reusable components
• Convention over Configuration: Sensible defaults

Code Example

Here is a typical example of how you might structure your code:

<?php

namespace App\Services;

class ExampleService
{
    public function process(array $data): array
    {
        return array_map(
            fn ($item) => $this->transform($item),
            $data
        );
    }

    private function transform(mixed $item): mixed
    {
        // Transform the item
        return $item;
    }
}

Best Practices

1. Write tests first — Red, green, refactor
2. Keep methods small — Single responsibility
3. Use type hints — Clarity and safety
4. Document your APIs — Your future self will thank you

Summary

Laravel 13 provides a powerful yet elegant approach to building modern applications. Start with the basics, experiment often, and gradually explore more advanced features as your confidence grows.
