Lightning provides developers with a lightweight framework for building advanced authoring experiences in Drupal 8. Developers gain a massive head-start when building great authoring experiences with Lightning, but it has not been a simple development roadmap. In this webinar, learn about some of the decisions we had to tackle, including: -Which modular functionality should be considered core to the authoring experience? -How will developers extend Lighting to create their own corporate or vertical distributions that leverage our authoring capabilities? -Should Lighting be divisible into its components? -How do we give developers the best upgrade experience possible? <spoiler> Composer </spoiler> We will also share more of the roadmap for Lightning including the Workplace Preview System, a Higher Education Scenario, and Decoupled Blocks integration. Also included will be a demo of all 18 of our user stories so you understand the intent and operation of the features we have implemented.

Build on Lightning
● Add dependencies
$ composer require drupal/MODULE_NAME:^8.0.0
● Dependency version constraints
○ Loose constraints when possible
○ Still have ability to patch

Build on Lightning (continued)
● Lightning is modular (turn off functional area)
● Doesn’t prevent you from using other solutions (Display
suite/Paragraphs)
● Non-drupal dependencies (e.g. php-twitter-api)

Extend Lightning
● Extend (released ~15 July)
● Givesa site-builders the ability to
override, delete and add to the
configuration that Lightning ships
with, during the installation process
● Enable additional extension
● Redirect path
● https://www.drupal.org/node/273450

# Defines additional tasks for Lightning
to perform after initial profile
# installation.
# List of additional modules to enable
after Lightning is installed.
modules:
- features
- acme_custom
- acme_product_content_type
- acme_theme_settings
- acme_lightning_settings
# A system path to redirect to once
installation is complete.
redirect:
path: /acme-install-complete
# Optional query string parameters.

Extend Lightning (continued)
● Consume
● High effort - edge case. Use Lightning’s modules in your
own profile
● Requires core patch: https://www.drupal.org/node/2743197
(Needs Work)
● Inherit (vision) Issue
o Five year old issue - might not be available… ever?

Lightning Components
• Tight coupling of functionality
• Standard authoring experience
• Future expectations
• Testing

Updates provided by Lightning
● Offloading maintenance
● Dependency (core and non-drupal)
● Composer update + composer.lock
○ Lock file (project, not Lightning’s) guarantees that all of
your devs are working from the same codebase within a
project
○ Running `update` allows you to get non-breaking updates
(e.g. core and contrib security updates) without needing
to wait for Lightning to make a new release
