Do not cache Twig template

Twig compiled templates are cached by default. To auto refresh teh compiled template, in settings.php, add this line:

defined('AT_DEBUG', TRUE);

Do not enable this on production sites.

Get available variables

{{ attribute(get_defined_vars(), 'context')|kpr }}

Render View with template:

{{ 'view_name'|drupalView({template: '@my_module/templates/views/view_name.html.twig'}) }}

To minimize your time on view template, just extends to default view template:

{% extends '@at_base/templates/views_view.html.twig' %}

{% block debug %}
  {{ attribute(get_defined_vars(), 'context')|dsm }}
{% endblock %}
