Smart and Dumb Components
summary
Argues that splitting UI into dumb components (pure view, receive props, emit events) and smart components (inject app-level services, hold state) makes large Angular apps more reusable and testable. Shows live human-demo of events flowing up to a dispatcher, demonstrates Redux-style dispatch and an RxJS/observable stream analogy, and reports that the pattern reduces cross-tree plumbing compared with passing root state everywhere. Recommends extracting reusable dumb pieces early and keeping service logic in container components.
