Understanding Service Classes in Laravel

# Understanding Service Classes in Laravel

Service classes are a powerful pattern for organizing business logic in Laravel applications.

## What Are Service Classes?

Service classes encapsulate business logic that doesn't belong in controllers or models. They:

- Keep controllers thin
- Make logic reusable
- Improve testability

## When to Use Services

Use service classes when:

- Logic spans multiple models
- Operations have multiple steps
- You need to reuse logic across controllers

## Example: PostService

```php
class PostService
{
public function create(User $user, array $data): Post
{
$slug = $this->slugs->generate($data['title']);

return $user->posts()->create([
'title' => $data['title'],
'slug' => $slug,
'status' => $data['status'],
]);
}
}
```

## Best Practices

1. **Inject dependencies** via constructor
2. **Return meaningful types** (Model, Collection, bool)
3. **Throw exceptions** for errors, don't return null
4. **Keep them focused** on one domain

## Conclusion

Service classes are essential for maintainable Laravel applications. Start using them today!
