# Using tenant specific facades

Facades behave like singletons. They only resolve once, and each use of the facade is against the same instance. For multitenancy, this may be problematic if the underlying instance behind a service, is built using tenant specific configuration.

If you only have a couple of tenant specific facade, we recommend only clearing them when switching a tenant. Here's a task that you could use for this.

```php
namespace App\Tenancy\SwitchTasks;

use Illuminate\Support\Facades\Facade;
use Illuminate\Support\Str;
use Spatie\Multitenancy\Contracts\IsTenant;
use Spatie\Multitenancy\Tasks\SwitchTenantTask;

class ClearFacadeInstancesTask implements SwitchTenantTask
{
    public function makeCurrent(IsTenant $tenant): void
    {
        // tenant is already current
    }

    public function forgetCurrent(): void
    {
        $facadeClasses = [
            // array containing class names of faces you wish to clear
        ];

        collect($facadeClasses)
            ->each(
                fn (string $facade) => $facade::clearResolvedInstance($facade::getFacadeAccessor);
            );
    }
}
```

Should you want to clear out all defined facades, you can use this code (provided by [Adrian Brown](https://github.com/spatie/laravel-multitenancy/discussions/240#discussion-3354768)) which will loop through all defined classes.

```php
namespace App\Tenancy\SwitchTasks;

use Illuminate\Support\Facades\Facade;
use Illuminate\Support\Str;
use Spatie\Multitenancy\Contracts\IsTenant;
use Spatie\Multitenancy\Tasks\SwitchTenantTask;

class ClearFacadeInstancesTask implements SwitchTenantTask
{
    public function makeCurrent(IsTenant $tenant): void
    {
        // tenant is already current
    }

    public function forgetCurrent(): void
    {
        $this->clearFacadeInstancesInTheAppNamespace();
    }

    protected function clearFacadeInstancesInTheAppNamespace(): void
    {
        // Discovers all facades in the App namespace and clears their resolved instance:
        collect(get_declared_classes())
            ->filter(fn ($className) => is_subclass_of($className, Facade::class))
            ->filter(fn ($className) => Str::startsWith($className, 'App') || Str::startsWith($className, 'Facades\\App'))
            ->each(fn ($className) => $className::clearResolvedInstance(
                $className::getFacadeAccessor()
            ));
    }
}
```
