A method for automating updates to configuration data includes coding a builder method within a source file for an application component and running the source file through a transformer engine configured to implement an interface within the source file. The builder method is implemented to construct an in-memory data structure representing one or more configuration data elements of a configuration object provided by a configuration service for the application component. The interface provides a mapping between one or more configuration data elements represented in the in-memory data structure and one or more corresponding data elements of a listener object representing changes to the configuration object. The mapping is implemented to update the in-memory data structure at runtime whenever a change to the configuration object is signaled to the listener object.
