Since Drupal 9.3, entity bundle subclasses can be created (see change record).
This module provides a Drush command that attempts to work similarly as barryvdh/laravel-ide-helper (it creates a file with all the fields of each bundle subclass).
Normal installation with composer:
TEMPORARY NOTE: The module is not yet uploaded to drupal.org.
composer require --dev drupal/subclass_ide_helper
drush en -y subclass_ide_helper
The ide helper file can be generated using the following command:
drush subclass_ide_helper:generate [entity,types] [--result-file=/foo/bar] [--excluded-classes=ClassName,AnotherClassName]
Or using the alias:
drush sih [entity,types] [--result-file=/foo/bar] [--excluded-classes=ClassName,AnotherClassName]
By default, the file generates docblocks for node bundles subclasses. Additional or different entity types can be specified, separated with a comma. Example:
drush subclass_ide_helper:generate node,media
By default, the file is created at the project root. The path and filename can be customized using the result-file option. Example:
drush subclass_ide_helper:generate --result-file=/foo/bar
To exclude a class (example, if there is a base node class extending the original for all nodes except for some):
drush subclass_ide_helper:generate --excluded-classes=ClassName,AnotherClassName
