React Patterns & Best PracticesEntry 10 of 10
Summary
| Concept | React | Angular |
|---|---|---|
| Compound components | Parent + Context + children | Parent component + ng-content + inject() |
| Shared state | useState in parent context | Signals on parent component |
| Per-item context | Nested AccordionItemContext | Inject AccordionItemComponent |
| Grouping parts | Object.assign(Root, { Item, ... }) | Exported component array |
| Misuse error | Context hook throws | NullInjectorError |
| Prop forwarding | ...props + ComponentPropsWithoutRef | Host attributes / button[appButton] |
| Render props | children: (item) => ReactNode | ng-template + ngTemplateOutlet |
| Generic lists | <T> + itemKeyFn | Generic class + track itemKeyFn()(item) |
| Debouncing | useRef timer / useDebouncedValue | debounceTime via toObservable/toSignal |
Compound components, render props, and prop forwarding all serve one goal: reusable components that give the consumer control without a bloated props API. Angular reaches the same goals with content projection, DI between parent and child components, ng-template, and host attributes, plus RxJS for timing concerns like debouncing.
