Logger Service

class LoggerService

This service is a wrapper for communicating with window.console, which manages the browser logger.

It is explicitly integrated with all classes for logging instantiations. It also allows logging errors, warnings and messages. The filters in the browser console can be adjusted to hide or show specific logs.

Browser console with verbose logging disabled

Browser console with verbose logging enabled

Recipe: Integrate this service with an APM (Application Performance Management) or observability service to upload logs for analysis.
