Custom configured Drupal Theme with Twig Pattern Lab

Here's a collection of the tools used to build this site; go make something cool with them!

  • Pattern Lab 2.0 - Drupal Edition - this collection of tools super charges what could be done with Pattern Lab 1.0 and is made up of these pieces:
    • Twig Engine for Pattern Lab - instead of the traditional Mustache engine in Pattern Lab 1.0, this uses Twig, which is much more powerfule, and is template language in Drupal 8!
    • Drupal Twig Components plugin - this adds extra functionality to Pattern Lab's Twig Engine, and let's use the essential link & trans Twig Functions; among many more!
    • Data Transform plugin - this super charges the JSON/YAML Pattern Sidecar data files to effectively let you pre-process data before rendering Twig templates. Incredibly powerful & flexible. Made by the awesome Aleksi Peebles.

The above tools give us a Twig powered, Drupal-aware Pattern Lab and can be spun up with:

	composer create-project pattern-lab/edition-drupal-standard

We've made a Drupal theme called Pattern Lab Starter that integrates the above Pattern Lab Drupal Edition along with Gulp tasks for common theme needs.


After making changes, run ../vendor/bin/drupal config:export -y and commit the files. If you just pulled or are deploying, run ../vendor/bin/drupal config:import -y to pull configuration changes present in the yaml files in web/sites/default/config/sync/ into the database. Very similar to Features in Drupal 7.

Install Drupal Modules

To install a new Drupal module, run this:

composer require drupal/MODULE_NAME:8.*

After enabling, do a ../vendor/bin/drupal config:export -y.

Who's behind this?

Built with love at Phase2 by Evan Lovely, Anne Sturdivant, and Chris Bloom. Most of the work to make this possible happened over at the Pattern Lab GitHub org with collaboration from Dave Olsen & Aleksi Peebles. Special thanks to Kellye Rogers and Frank Febbraro for supporting this internal project and wanting to share it with the community!
