To add a new field to the customers module, the module extension system injects the UI component and data structure through UMES. This requires knowledge of the application's module configuration to map the extension correctly.

To intercept and transform API requests, API interceptors within the module extension system validate, enrich, or modify payloads before they reach core logic. This allows developers to alter request flows without changing base endpoints.

To customize UI components, the module extension system allows developers to wrap or replace existing UI elements. This enables adding new fields or filters to forms and tables directly through the extension configuration.

To react to domain events, event subscribers in the extension system listen to emissions from other modules. This allows your custom extensions to trigger logic automatically when specific system actions occur.

Using the Universal Module Extension System requires knowledge of the application's module structure and configuration. This understanding is necessary to correctly target core modules for extension and UI customization.

To block or validate mutations before entity persistence, mutation guards intercept data changes and enforce validation rules. This prevents unauthorized or invalid data from saving to the database within the extended module structure.
