Spiral does provide ViewModel implementation by default, but rather simply access to rendering functions of view templates.
By default your application view templates are located in 'app/views' directory and can be invoked by file name.
Read more about view component to understand how to configure view namespaces and connect more rendering engines.
You can render any of your template using ViewsInterface dependency or shortcut views:
public function indexAction()
{
return $this->views->render('template', [
'variable' => 'Some value'
]);
}
Be free to implement your own buffer class between rendering engine and controllers when needed:
class ViewModel extends Service
{
private $name;
public function __construct(string $name)
{
$this->name = $name;
}
public function __toString()
{
return $this->views->render('template', [
'name' => $this->name
]);
}
}
public function indexAction()
{
return new ViewModel('some name');
}
