Metal.js AOP Utility

metal-aop is a utility package that provides Aspect-Oriented Programming (AOP) capabilities specifically for applications built with the Metal.js framework. AOP allows developers to modularize cross-cutting concerns such as logging, security, and transaction management, by defining advice (code to be executed) and applying it at specific join points (execution points) in the application's flow. The package's latest stable version is 3.0.0, released approximately eight years ago. However, the underlying Metal.js framework has been officially deprecated by Liferay, its primary maintainer, with no active staffing for open-source support and no future plans to use the framework. Consequently, metal-aop is effectively an abandoned project, meaning it receives no new features, bug fixes, or security patches. Its differentiators were primarily its tight integration with Metal.js's component model, which is no longer actively developed.
