If you want to install Magis as symfony bundle you should use MagisBundle
composer require pjpawel/magis-bundle
If you want raw view service and view classes use (this repository)
composer require pjpawel/magis
\pjpawel\Magis\ViewDispatcherService::class // service to dependency injection
\pjpawel\Magis\View\DirectView::class // simple view class that has method render() to ... render template :)
\pjpawel\Magis\View\MagicView::class // rich view class
You should use ViewDispatcherService
as dependency injection service.
You can create custom service to render view or use create Views directly.
