Drupal 8 offers developers many exciting new features to use in building websites. Have you tried configuration management? How about the new Symfony based routing system? Twig? Cache tags? Each of these systems is extremely powerful and will let you build websites like never before.

4. Drupal 8: On It’s Own Terms
Drupal 8 is ready for production
(and has been so for awhile)
There isn’t always “a module for that”
(but the architecture makes that OK)
“Content Management Features” are A+
(this makes site architecture much easier)

5. As a developer:
I never want to use Drush Make again

6. Composer for Patch Management
https://github.com/cweagans/composer-patches.git
"patches_applied": {
"remote video URLs": "https://www.drupal.org/files/issues/2728241-2.patch",
"default ref ID from logic to base fields": "https://www.drupal.org/files/issues/2731915-4.patch",
"IEF form handler": "https://www.drupal.org/files/issues/2743289-2.patch",
"Add a field formatter for the player": "https://www.drupal.org/files/issues/2803173-8.patch",
"Add AMP video player integration": "https://www.drupal.org/files/issues/2817233-4.patch"
}

7. As a Site Owner:
I want to ensure nobody can
change configuration on
production.

8. Config Read Only
https://www.drupal.org/project/config_readonly
To enable read only mode, enable this module
and add this to your settings.php:
$settings['config_readonly'] = TRUE;

9. As a Developer:
I want to have better test
coverage for my Drupal code.

10. Testing Improvements
public function testSessionExpiration() {
$this->drupalGet('<front>');
$session_assert = $this->assertSession();
$page = $this->getSession()->getPage();
for ($i = 0; $i < 25; $i++) {
$page->clickLink('Link to front page');
$session_assert->statusCodeEquals(200);
}
}
}

11. As a Themer:
I want to hide the sidebar...
but only on a few pages.

13. Twig Blocks
“Blocks are used for inheritance and act as placeholders and replacements at
the same time.”
- http://twig.sensiolabs.org/doc/2.x/tags/block.html

14. Twig Blocks
{#
/**
* @file
* Theme override to display a 404 page.
....
*/
#}
{% extends 'page.html.twig' %}
{% block sidebar_first %} {% endblock %}

15. Twig Blocks
{% block sidebar_first_wrapper %}
{% if page.sidebar_first %}
<aside class="column-sidebar sidebar" role="complementary">
<div class="container">
{% block sidebar_first %}
{{ page.sidebar_first }}
{% endblock %} {# /sidebar_first #}
</div> <!--/.column-sidebar-container -->
</aside> <!--/.column-sidebar -->
{% endif %}
{% endblock %} {# /sidebar_first_wrapper #}
