  3. 10 core/lib/Drupal/Core/Extension/module.api.php \hook_module_preinstall()

Perform necessary actions before a module is installed.

Parameters

string $module: The name of the module about to be installed.

bool $is_syncing: TRUE if the module is being installed as part of a configuration import. In these cases, your hook implementation needs to carefully consider what changes, if any, it should make. For example, it should not make any changes to configuration objects or configuration entities. Those changes should be made earlier and exported so during import there's no need to do them again.
