# DI and actions

The package has two equivalent entry points. The Translatable facade is the shortest and the recommended default. The manager, RoundlyConsulting\\Translatable\\Support\\TranslationManager, is the facade’s root: bound as a singleton and injected through the constructor, it exposes the identical API as an explicit dependency, with no static calls:

```php
use RoundlyConsulting\Translatable\Support\TranslationManager;

final class UpdateTopicTranslations
{
    public function __construct(private TranslationManager $translations) {}

    public function handle(Topic $topic, array $input): void
    {
        $topic->setTranslations('name', $this->translations->fromInput($input['name'] ?? []));
    }
}
```

Both paths reach the same singleton:

```php
use RoundlyConsulting\Translatable\Facades\Translatable;
use RoundlyConsulting\Translatable\Support\TranslationManager;

app(TranslationManager::class) === Translatable::getFacadeRoot(); // true — one singleton
```

## No action classes

There are no action classes to compose into your own jobs or commands: the package does pure locale-map computation — no database write, queue, mail, event or HTTP call — and the manager serves it directly. Call the manager (or the facade) from your own actions instead.

## Swapping the manager

TranslationManager is deliberately not final — it’s the package’s one designed extension seam. Extend it, override a method and swap it in: its sibling methods observe the override polymorphically, and facade calls and every HasTranslations model observe the subclass:

```php
use RoundlyConsulting\Translatable\Facades\Translatable;
use RoundlyConsulting\Translatable\Support\TranslationManager;

Translatable::swap(new class extends TranslationManager
{
    public function supported(): array
    {
        return ['en', 'sk', 'de'];
    }
});

Translatable::supported();                        // ['en', 'sk', 'de']
Translatable::fromInput(['de' => 'Investieren']); // ['de' => 'Investieren']
$topic->missingLocales('name');                   // now also reports 'de'
```

## Internals

Support\\FallbackResolver and Support\\LocaleGuard are @internal building blocks — call Translatable::resolve(), ensureLocale() or isSupported() instead. The locale-key format check stays a fixed floor on every write path and scope; it never depends on a method you override.
