RxJS Advanced Patterns – Operate Heavily Dynamic UIs
summary
A concrete recipe for managing highly dynamic UIs with RxJS: build a counter app with multiple controls, background intervals and restart behavior, and implement custom operators (scan/scan‑like, latestFrom, worker/collector) to separate reads and writes. Uses Event Sourcing and CQRS to store streams of changes, centralizes side effects for lifecycle-safe teardown, and provides copy‑paste‑ready code that reduces subscriptions and simplifies state updates for a performant implementation.
