Processor Pattern with Angular Dependency Injection
summary
Claim: implement the Processor (Command) pattern inside Angular by registering multiple implementations under one InjectionToken and multi provider and injecting an array with @Inject to pick one by name. Concrete builds include ninja weapon processors and chart processors that replace a monolithic service of ~30 functions with small classes, strong-typed names, and private transform/draw methods. Integration with NgRx caching prevents repeated API calls so charts load from store after the first fetch; demo shows it works and simplifies unit testing.
