Creating and Applying Drupal Patches

Creating a Drupal patch can be a confusing process. Here are my own notes for helping out my future self. The core solution has some other concepts around it that all work together to patch a module.

The Solution

The key to the solution, and described aptly as a 'good [best] practice' by Stef VanLooveren. The core of the solution has three basic steps: 

Drupal Lenient Module Support Installation

1. Install Development Composer Packages

   composer require --dev mglaman/composer-drupal-lenient composer require --dev drupal/backward_compatibility

2. Configure Lenient Module Allowed List

   composer config extra.drupal-lenient.allowed-list '["drupal/responsive_menus"]'

3. Update Composer Dependencies

   composer update

4. Enable Backward Compatibility Module

   ddev drush en backward_compatibility
