Customer Reorder plugin is based on two processes:

• reorder processing
• reorder eligibility checking

They are both based on Symfony's compiler passes and configured in services.xml file.

ReorderProcessing and EligibilityChecking are independent processes - once a Reorder is created using Processors (services tagged as sylius_customer_reorder_plugin.reorder_processor), the created entity is passed to Eligibility Checkers (services tagged as sylius_customer_reorder_plugin.eligibility_checker).

Hence, both processes can be extended separately by adding services that implement ReorderEligibilityChecker and are tagged as sylius_customer_reorder_plugin.eligibility_checker or implement ReorderProcessor and are tagged as sylius_customer_reorder_plugin.reorder_processor.

Both Reorder button layout and action performed on clicking it are defined in reorder.html.twig template which is declared in config.yml file.

What's more, since Order is a Resource, major part of its configuration is placed in *.yml files. Without using the plugin, Order had Show and Pay actions. Adding Reorder action required extending order-related behaviours in config.yml file.
