Next Level Twig: Extensions

By Will Long

Drupal 8 features many enhancements, one of the most-prominent being the implementation of the Twig templating system. But are you really getting the most out of your Twig? If you’re not using Twig extensions, then no--you’re not.

Twig extensions allow developers to add processing capabilities to Twig’s template rendering via via custom filters and functions. The Twig Tweak module is a popular solution for adding common functionality to Twig, and as developers we can provide even more power to the folks working with our templates.

This session will cover:

* Functionality provided by the core and contrib extensions
* Implementing custom Twig extensions
* Practical examples of functionality possibly through Twig extensions
