Processor Pattern with Angular Dependency Injection
summary
Shows how Angular DI uses InjectionToken plus multi provider to register multiple implementations and @Inject to receive them as an array so code picks one by name at runtime — demonstrated with four processors (sword, short stick, nunchucks, sake) and a real dashboard of chart processors. Replaces a monolithic service of about 30 functions with per-chart classes, and integrates with NgRx so data fetches once and uses NgRx caching from the store.
